hi everybody my name is alicia in this

lesson

i'm going to talk about the differences

between

can and could this lesson is going to

include a lot of information and some

example sentences

if you want to know more about any of

these points

try searching our youtube channel for a

lesson with some more detail

okay let's get started with the first

point number one

up here the first way to use can

and could that i want to talk about is

to express

abilities so an ability that refers to

something we are

able to do or not

able to do when we want to talk about

a present ability something we can do

now i just used can to express that

something we have the ability to do

now we use can plus

a present tense verb this

expresses a present ability something we

can do now it's possible for us to do

that now

to make the negative form we use can not

or can't can't i can't do something

when we want to talk about a past

ability

for example something in our childhood

or something when we were

in school we use could

plus a present tense verb again so this

verb

in past and present form uses a present

tense in this position this verb here

we always use a present tense verb in

this position

this expresses a past ability we know

this because we're using

could in this pattern let's take a look

at a couple

of examples of this first

a pair of present tense statements the

first one here is

i can speak english

i can speak english so a very basic

pattern

hopefully many of you can use here we

see

can plus speak in this case

speak is a present tense verb and then

we have the language here

so a reminder we use speak when we're

talking about our language abilities not

i can talk

or i can say but i can speak english

of course we could change this to a

negative i can't

speak french for example we can use the

same pattern

just replacing can with the negative

can't

i can't let's look at a different one

though she

can't swim she can't swim

so here my subject has changed yes to

she

there's no change here to reflect the

subject

and swim my verb following

can't remains in the present tense so

these are very basic examples

of how to express our abilities with can

and can't in present so let's compare

this then

to using could to make past tense

expressions

so as i said could will change from can

to could

but the verb does not change let's see

how we use this

he could speak spanish

when he was a kid he could speak

spanish when he was a kid this is a

past tense ability statement and

something you'll notice is very common

in these past ability statements

is a point in time or like a time period

when so he could speak spanish

when when he was a kid

so you'll notice this is also in past

tense not when he is a kid

when he was a kid at that point in time

in the past it's finished now

so we'll often include a time period or

a point in time in the past

to help us understand this ability

one more example here this is a negative

example

we couldn't watch the movie

it was too violent we couldn't watch the

movie

it was too violent so here this is a

past

tense negative couldn't is the reduced

form

of could and not we could not watch the

movie

so we could say yes this is kind of like

a possibility statement

which i'll talk about a little bit later

but we can also

use this kind of expression to explain

it was not

possible for us to watch the movie like

i didn't have

the ability to watch that movie we might

use an expression like this

so the reason here instead of a point in

time

which we probably understand from the

situation like we couldn't watch the

movie last night or we couldn't watch

the movie last weekend

instead of a point in time i included

a reason so why

couldn't i watch the movie or why

couldn't we watch the movie

it was too violent so it

is the movie the movie itself this was

past

tense a past situation violent violent

so this means there's

like maybe like action people attacking

other people hurting other people

maybe very graphic scenes extreme or

intense

images it's too violent so

we can use couldn't to talk about these

kinds of things too

i'll explain a little bit more when i

talk about point number three

in this lesson so this is how we use can

and could for present and past tense

abilities all right let's continue on to

point number two for this lesson

point two is using can and could for

requests and for

offers so this is actually

a bit simpler than this point i think

the difference here when you're making

requests and offers with can

and could it's just that can sounds more

casual it sounds a little bit more

friendly

good sounds a bit more polite so both of

these

are okay to use in most situations

if you want to sound a little bit more

formal a little bit more polite

you can use could in most everyday

situations we use

can so we begin our request

or our offer usually with can and we

make a question with it

there are a couple of other variations

too i'll show you

a couple examples so let's look at using

can first so let's begin our sentence

our question with

can here can you help me

with my homework can you help me with my

homework

this is a request please help me in

other words

so instead of please help me with my

homework which sounds

like a word desperate maybe please help

me

using can you is kind of like

asking do you have the ability to

help me with my homework is it possible

would it be okay

so it's a bit softer than using please

so please help me

it's okay there's not a communication

problem

but can you help me with my homework

sounds a bit nicer

a little bit more friendly now let's

look at using

can to make an offer i

can buy you a coffee if you like

so if you like is like if you want one

if it's okay do you want one if you like

a nice offer expression i can buy you a

coffee

so here in the offer pattern can

comes before the verb so again

we can think of this a little bit like

an ability so it's like the speaker is

saying

right now i have the ability to buy you

a coffee

would you like a coffee but that doesn't

sound natural

it's like saying right now this is

possible i can buy you one

so is that okay i can buy you a coffee

if you like

so this is a nice friendly way to make

an

offer let's compare this then to using

could in similar patterns so as i said

could is going to sound a little bit

more formal a little more polite

first example is a request could you

please send me the files

could you please send me the files so

i've added please here to show again

it's a little more formal

and in this case perhaps it's a business

situation

maybe it's a business situation send me

the files

so this is a work request perhaps

maybe that's why the speaker is using

could and

please you'll also notice that when i'm

using

could or can to create a request

question i'm following the word can or

could

with the person i want to help me

so in this case i'm using you for both

of my sentences

but you might hear some sentences where

the speaker

asks for someone else to do something so

this person is not in the conversation

i'm talking to someone else

i would like ask this person please ask

that person to do something like

can he join the meeting later for

example

that's something that you might hear too

for these requests and for

probably a lot of requests though we use

you

after can or could but you may hear he

or she or they used in these patterns

too

okay let's finish this part with an

offer

using could if it's helpful

we could teach your staff about

the new software if it's helpful

if it's helpful so again it's a

softening expression

kind of like if you like but this sounds

a little more formal

if it's helpful if you like we could

teach your staff about the new software

so this is an

offer we are offering to teach your

staff

about the new software we use could

to do that we could do this like again

we have this ability yes but in this

case

could is not referring to a past tense

situation

we're using could to make a polite offer

we could teach your staff so this is one

example of how to do it

okay so this is how we use can

and could to make requests and to make

offers let's continue then i want to

move back to this side of the board

to point three for this lesson so i

talked a little bit about this

in point number one but we also use uh

could to talk about present and

past possibility so first let's look at

a couple of sample patterns this is

probably i think these two

the most common patterns you might hear

they use could and could not so

first an explanation in many of these

possibility statements we use could

plus the verb be plus

often some kind of like adjective phrase

when we make the negative form we use

could not

plus the verb be plus our adjective

phrase

so when we make a past tense possibility

statement

we follow a similar pattern but we use

have been instead of be

so this pattern is our present

tense possibility statement a present

situation

have been this could have been pattern

refers to a past possibility so let's

take a look at some example sentences

that use these patterns first

[Music]

the meeting starts at 2 but

nobody's here i could be

in the wrong place so here is my

could be so i included this part

to show the situation situation and

context are quite important

for these kinds of statements so in this

case

the speaker is waiting for a meeting

that starts at

two and the speaker is thinking to

himself or herself hmm

the meeting starts at 2 but nobody's

here

so i could be

in the wrong place another way to say

that is

it's possible i am in the wrong

place wrong means incorrect i'm in the

incorrect place

the meeting is somewhere else so could

be expresses this possibility there's a

possibility

i'm in the wrong place you might also

hear

might used here instead of could i might

be in the wrong

place so the difference between might

and could

is very small in this situation i could

be

in the wrong place is very neutral it's

not like positive or negative

there's not a high chance or low chance

just it's

possible if i said i might be in the

wrong place

it sounds like there's a higher chance

like maybe uh 50 or 60

it's not a rule but there's a higher

chance i'm

in the wrong place like i might be in

the wrong place

sounds a little bit more certain than

i could be in the wrong place so it's

just the level of certainty there

so i could be in the wrong place let's

look at another example

this one is a past situation a past

situation

it's a conversation person a says hey

was that michael so you're on the street

was that michael over there

in that coffee shop for example b says

no that couldn't have been michael

he's out of town out of town so out of

town means away from the city

so here i'm using couldn't have

been michael so that means that guy

over there you pointed to that couldn't

have been michael could not have been

this means it's impossible that was

michael

it is there's no chance absolutely no

chance that was michael

i know because he's out of town

he's out of town he's not here so

couldn't have been

means impossible that couldn't have been

michael

he's out of town so we use these two

patterns to express

possibility and yes please keep in mind

that this negative

i've used here couldn't have been

means not possible not possible

so couldn't be as well the negative in

the present form

is also reflective of an impossible

situation

so here i used the positive could be

meaning it's just possible but when you

use the negative form it means something

is

impossible so for example let's imagine

the speaker in this situation

came to the correct place so the speaker

looks at his or her watch and says hm

the meeting starts

at two o'clock and everybody is here

i couldn't be in the wrong place it's

impossible

i'm in the wrong place because everybody

is here

i know i'm in the correct place so i

couldn't be

in the wrong place i'm in the correct

room so impossibility

is reflected with use of the negative

form

with the positive form it's just simple

possibility very neutral

final point here we make questions with

this

same kind of pattern so we do this

often when we're thinking like

thinking to ourselves so i'm alone and

i'm thinking to myself about something

or when i need to confirm something

with someone else so an example could

this be

the correct building so could this be

the correct building

i would use this if i'm like checking my

phone checking the gps

on my phone searching for a place i have

a meeting

something i'm looking around and i think

this building is correct i think to

myself

um could this be the correct building

so that's a that's a sentence or a

question

a native speaker might say um i feel

in most situations though we just say is

this the correct building

we just say it with is could this

sounds more like is it possible this is

the correct building

so it might sound a little bit more

formal i feel like

in everyday speech more commonly we say

is this the correct building

but you might sometimes hear could used

in this kind of pattern let's look at

one more

example could i have made the wrong

decision could i have made the wrong

decision

so again the speaker is thinking about

something in the past

or maybe they're speaking to a friend

could i

have made we know this is a past

expression because of this grammar right

here

could i have made have made

shows us that this is something the

speaker chose

chose to do in the past so could i have

made the wrong decision

could be the speaker thinking out loud

to himself

or herself is it possible i made the

wrong decision

or the speaker could be asking someone

else could i have made the wrong

decision

and they're expecting some kind of

opinion so

we're using these patterns to talk about

possibility

so you might hear some questions that

use could

in this way but keep in mind these are a

little bit different

from these offer type questions we

talked about

okay let's move along then to point

number four

for this lesson point number four is

about

unreal situations unreal situations

so when we use could with unreal

situations there are

quite a few patterns that we can use

but i wanted to introduce just a couple

of very

um kind of simple ways that we use this

so i've i've made just this very simple

um pair of if clause and main clause

and i've got here main clause with could

so a point to be careful of is when

you're making

your unreal statement and you're using

this

if something something main clause

something something pattern

make sure your could

is in your main clause we do not use

could in the if clause so no could goes

here

your modal verbs in general don't put

them in the if clause

put them in the main clause so that

means like will won't may might

all those words put them in your main

clause could as well

so there are a few different patterns

that we use with unreal situation

so i want to talk about these two they

have a little bit of challenging grammar

so let's take a look

first one if i won the lottery

i could buy a house if i won the lottery

i could buy a house here's my if clause

if i won the lottery

comma i could buy a house so here is

could

so could is used yes to talk about this

unreal situation so we know it's not

real

because of this if right here so that

means i have not won the lottery

uh by the way lottery is a game so we

can

win a large money prize uh

by chance so we buy a card or a ticket

and maybe we get a large prize for that

it's a game kind of gambling anyway

if i won the lottery meaning i have not

won the lottery but if i did

i could buy a house so this could

is reflective of this possibility point

or kind of you can think of it as

disability point too

a little bit but it means i would be

able to

so i would have lots of money so it

would be

possible to buy a house so we use

could to reflect that if i won the

lottery

i could buy a house possibility here

so we do not use can in this case

we use could because it's an unreal

situation

we don't use this can to talk about

these unreal situations please use

could here let's upgrade a little bit

more challenging grammar here

if clause again if we had finished

work earlier today if clause if we had

finished work earlier today

we could have gone to the movie theater

we could have gone to the movie theater

so this is a very challenging sentence

to understand

let's take a look if we had finished

work earlier

earlier today earlier than we did so we

finished work at

8pm but if we

had finished so this is referring to a

past

action it's complete if we finished work

or if we had finished work

at 5 pm for example earlier

then we finished we actually finished at

8 but if we had finished earlier

maybe 5 we could have gone to the movie

theater

so could have gone this use of could

refers to an activity in the past

a possible past activity that would have

been possible

if this part were true so again

to recap we finished work at eight we

could not go to the movie theater

in this situation but if we finished

work

earlier if we had finished work earlier

for example

5 pm in that situation which is not real

did not happen we could have gone to the

movie theater

it would have been possible so we use

these kinds of sentences to talk about

all this stuff in the past that did not

happen

but we just want to dream about it so

this is an example of how we use

could and again we use could here not

can we make a past tense examples

or past tense pattern rather by using

have

plus the past participle form of the

verb so again a challenging grammar

point but this is one we use a lot to

dream

about past situations okay

let's finish this lesson with point

number five kind of a small point

so i want to go back to point two here

we talked about using

can and could to make requests and

offers

another thing you might hear is using

can't

and couldn't to make suggestions

so you'll notice all of these use the

negative

form so the difference here

is that when you use the positive as we

talked about

in point two positive form sounds a bit

more like a request

it's like you want something when you

use the

negative though it's like you're giving

something you're giving a suggestion

so using the can is a little more like

you're pulling

maybe information or you're pulling

something using

can't is like you're you're giving a

suggestion or you're giving advice

so we use can't or couldn't in the same

way that we use can

and could to sound a bit more polite

and we often pair this we often use this

together

with just just as like a is a modifier

it changes the feeling

to sound like simpler or a little more

gentle like just a simple suggestion

just a small suggestion

so can't you for example you is very

common here

as i talked about in these patterns

but we can use he she they we and so on

um plus for present tense uh situations

for present tense

um sentences suggestions we use a

present

tense verb here for couldn't we can talk

about

again present tense situations or we can

imagine as we did here we can imagine a

past tense situation

and you want to give advice you want to

give a suggestion

about that past situation you can do

that with

couldn't plus past participle verb form

as we did here so some examples of this

first can't you just leave earlier

can't you just leave earlier so someone

who's always late for example

can't you just leave earlier you could

remove just that's okay

can't you leave earlier but just softens

it it's like

this is a small suggestion can't you

just leave earlier

another one couldn't you just call to

confirm

couldn't you just call to confirm it's a

small suggestion

so sounds a little more polite because

we're using couldn't here

finally couldn't you have created

a bigger budget for the project couldn't

you have created a bigger budget for the

project

so this is another past tense situation

so we're dreaming here again

so couldn't you have created shows us

this was a past

thing that someone did the listener did

so the speaker created or sorry the

listener

created a budget for the project the

speaker is saying

couldn't you have created a bigger

budget

for the project so this is giving a

suggestion

or rather the speaker's opinion about a

choice

or a decision the listener made in the

past

so we use these negative forms to give

suggestions to give advice to give

opinions

uh not so much requests or offers

okay so that's a lot of information

a lot of different ways to use can and

could and also there are some patterns

there are many patterns

that i did not talk about in this lesson

so you can

try to i think use these five points

maybe

to understand a little better the

different uses of

can and could as you listen and as you

read as well so i hope that this is

helpful for you

again if you want to know more about any

of these points

you can try searching our youtube

channel to see if there's another

whiteboard video

想从第一堂课开始说真正的英语

在

englishclass101.com 注册您的免费终身帐户 大家好，我的名字是本课中的艾丽西亚，

我将讨论

can 和could 之间的区别本课将

包括很多内容 信息和一些

例句

如果您想了解更多关于

这些要点的信息，请

尝试在我们的 youtube 频道中搜索

更详细的课程，

好的，让我们从

这里的第一点开始第一种使用方法 can

and could that 我想谈论的

是表达

能力，所以

当我们想

谈论目前的能力时，我们可以做或不能做的事情，我们现在可以做的事情，

我只是用来表达

我们拥有的东西 能力

现在我们用 can 加上

一个现在时动词 这

表示现在能力 某事我们

现在可以做 我们现在可以这样

做 使我们使用的否定形式 can not

或 can't can 'ti can't do something

当我们想谈论过去的

能力

时，例如我们童年

时的某事或我们在学校时的某事，

我们再次使用 can

加上现在时态动词，所以这个

过去和现在形式的动词使用现在

时态 在这个位置这个动词在这里

我们总是使用现在时动词在

这个位置

这表达了过去的能力我们知道

这是因为我们

在这个模式中使用了可能让我们看

一下这个的

几个例子首先

一对现在时 陈述

这里的第一个是

我会说英语

我会说英语所以一个非常基本的

模式

希望你们中的许多人可以在这里使用我们

看到

可以加上在这种情况下

说说话是现在时态动词然后

我们在这里有语言

所以提醒 当我们

谈论我们的语言能力时，我们使用 speak not

i can talk

or I can say but I can speak English

当然我们可以将其改为

否定我不会

说法语 例如我们可以使用

相同的模式

只是 r 用否定代替 can

我不能让我们看一个不同的，

虽然

她不会

游泳 后面的

can't 保持现在时，所以

这些

是如何用 can 和 can't 现在表达我们的能力的非常基本的例子，

所以让我们比较

一下

然后用 can 做过去时

表达，就像我说的那样，可能会从 can

to can

但动词没有改变 让我们

看看我们如何使用它

他小时候会说

西班牙语 他小时候会说西班牙语 这是

过去时的能力陈述，

你会注意到这很

常见 这些过去的能力陈述

是一个时间点或一个时间段

，所以他小时候可以说西班牙语

，

所以你会注意到这也是过去

时态，而不是

他小时候的时候

过去的时间点现在已经完成

所以我们 '通常会包含过去的时间段或时间

点，

以帮助我们理解这种能力

这里再举一个例子这是一个反面

例子

我们不能看电影

它太暴力了我们不能看

电影

它是 太暴力了，所以这是

过去

式否定，can't 是

can 和 not 的简化形式，我们不能看

电影，

所以我们可以说是，这有点像

一个可能性陈述

，我稍后会谈到

但是我们也可以

用这种表达方式来

解释我们不可能像

我

没有能力看那部电影一样看电影我们可能会

使用这样的表达方式

所以这里的原因而不是时间点

我们可能从这种

情况中了解到，比如我们昨晚不能看

电影，或者我们

上周末不能看电影，

而不是某个时间点，我包括

了一个原因，所以

我为什么不能看电影或为什么

不能看电影 我们看

电影太暴力了 所以这

是电影 电影本身 这是

过去

式 过去的情况 暴力 暴力

所以这意味着

可能像动作 人们攻击

他人 伤害他人

可能是非常生动的场景 极端或

激烈的

图像 它太暴力了所以

我们可以使用 不能 也谈论这些

类型的事情，

当我在本课中谈论第三点时，我会稍微解释一下，

所以这就是我们如何使用 can

和 could 来表示现在和过去时的

能力 好吧，让我们继续第二

点 对于本课，第二

点是使用 can 和 could 来表示

请求和

提供，所以这实际上

比这一点简单

一点 听起来更

友好

好 听起来更有礼貌 所以这两个

都可以在大多数情况下使用

如果你想听起来更

正式一点 更

有礼貌 你可以 n 在我们使用 can 的大多数日常

情况下都使用

can，因此我们通常使用 can 开始我们的请求

或报价，然后我们

用它提出问题

还有其他一些

变化我将向您展示

几个示例，所以让我们看看使用

can 首先，让我们开始我们的句子，

我们的问题

可以在这里，

你能帮我做作业吗？你能帮我做作业吗？

也许请帮助

我

使用你能不能有点像

问你有能力

帮助我完成我的家庭作业是否可以

这样它比使用请更柔和

所以请帮助我

没关系没有沟通

问题

但是 你能帮我做作业吗

听起来

更好一点 更友好一点

想 一个如果你喜欢

一个不错的报价表达我可以给你买

一杯咖啡

所以在报价模式中可以

出现在动词之前所以

我们可以再次把这看作

是一种能力所以就像说话者现在

说

我有 给你买

咖啡的能力

你想要一杯咖啡，但这听起来不

自然

，就像说现在这是

可能

的 提出

要约的方式 让我们将其与

在类似模式中使用 can 进行比较，所以正如我所说的那样，

can 听起来会

更正式一点 更有礼貌

第一个例子是请求 你可以

把文件

发给我吗 你可以发给我吗 文件，所以

我添加了请在这里再次显示

它更正式一点

，在这种情况下，也许这是一个业务

情况，

也许这是一个业务情况给我发送

文件，

所以这是一个工作请求，

也许这就是演讲者

使用 can 和

p 租约您还会注意到，当我

使用 can 或 can 创建请求

问题时，我正在使用 can 或

could

与我想帮助我的人一起使用这个词，

因此在这种情况下，我将您

用于我的两个 句子，

但您可能会听到一些句子

，说话者

要求其他人做某事，因此

此人不在对话

中 例如，稍后会面

，对于这些请求和可能的很多请求，您也可能会听到

这些请求，

尽管我们

在可以或可能之后使用您，但您可能会听到他

或她或他们在这些模式中使用

过，

好吧，让我们用一个结束这部分

如果它有帮助，

我们可以向您的员工

介绍新软件，如果它有帮助，我们可以向您的员工提供使用，

如果它有帮助，那么它再次是一种

软化的表达

方式，如果您愿意，但

如果它有帮助，这听起来更正式一些，如果您愿意，我们可以

向您的员工介绍新软件，

所以这

是我们向您的

员工

介绍我们使用的新软件的提议 可以

这样做 我们可以再次这样做

我们有这种能力 是的，但在这种

情况下

可能不是指 过去式

我们使用 can 来提供礼貌的报价

我们可以教您的员工，所以这是一个

如何做到的例子

回到董事会的这一边，

回到本课的第三点，所以我

在第一点中谈到了一点，但我们也用呃

可以谈论现在和

过去的可能性，所以首先让我们

看几个示例模式 这

可能是我认为这

两种最常见的模式，你可能会听到

他们使用 can 和 could not 所以

首先在

我们使用的许多可能性陈述中进行解释 can

加上动词 be 加上

当我们经常使用某种形容词短语时 使我们使用的否定形式

could not

加上动词 be 加上我们的形容词

短语，

所以当我们做出过去时的可能性

陈述时，

我们遵循类似的模式，但我们使用

has been 而不是 be

所以这个模式是我们现在

时的可能性陈述一个现在的

情况

一直这可能是模式

指的是过去的可能性所以让我们

先看一些使用这些模式的例句

[音乐

] 会议从 2 点开始，但

没有人在

这里 所以我把这部分包括在内是

为了说明情况和

上下文

对于这类陈述非常重要，所以在这种

情况

下，演讲者正在等待

从两点开始的会议，

而演讲者正在思考

自己，

嗯，会议从 2 点开始 但是没有人在

这里

所以我可能

在错误的地方另一种

说法是

我可能在错误的

地方错误的意思是不正确的我在

错误的

地方我 eting 在其他地方，所以

可以表达这种可能性，有

可能

我在错误的地方，你也可能

听到

可能在这里使用，而不是我

可能在错误的

地方，所以

在这种情况下可能和可能之间的差异非常小 我可能

在错误的地方是非常中性的 这

不是正面或

负面的 没有高或低的机会

只是

如果我说我可能在

错误的地方是

可能的 听起来可能有更高的机会

呃 50 或 60

这不是规则，但

我

在错误的地方的可能性更高，就像我可能

在错误的地方

听起来比

我可能在错误的地方更确定，所以这

只是那里的确定性水平，

所以我可能是 在错误的地方让我们

看另一个例子

这个是过去的情况

b

说不，那不可能是迈克尔，

他不在城外，所以在

城外意味着远离城市，

所以我在这里使用的不可能

是迈克尔，所以这

意味着你指的那个人可以 't

have been michael 不可能

这意味着不可能是

michael

这是不可能的 绝对

不可能是 michael

我知道因为他不在城里

他不在城里 他不在这里所以

不可能是不可能的 不可能是

迈克尔，

他不在城里，所以我们使用这两种

模式来表达

可能性，是的，请记住

，

我在这里使用的这个否定不可能

意味着不可能，不可能，

所以也不可能

目前形式

的否定也反映了不可能的

情况，

所以在这里我使用肯定可能

意味着它只是可能的，但是当你

使用否定形式时，它意味着某事

是

不可能的，所以例如让我们想象一下

说话者在这种情况下 ion

到了正确的地方，所以演讲者

看了看他或她的手表，然后说

嗯，会议

从两点开始，每个人都在这里

在这里

我知道我在正确的地方所以我

不能

在错误的地方我在正确的

房间所以

通过使用否定

形式

和肯定形式来反映不可能这只是简单的

可能性非常中性

最后一点 在这里，我们用

同样的模式提出问题，所以我们经常这样做，

当我们像在

思考自己一样思考时，我独自一人，

我在思考某事，

或者当我需要

与其他人确认某事时 例如，

这可能

是正确的建筑物吗？这可能

是正确的建筑物

吗？如果我想检查我的手机检查我手机上的 gps 寻找一个我开会的地方我正在环顾四周，我想

这个 建筑是正确的我 想一想，

嗯，这是否是正确的建筑，

所以这是

一个以母语为母语的人可能会

说的

句子或问题 有没有可能这

是正确的建筑，

所以听起来可能更

正式一些我觉得

在日常讲话中更常见的是我们

说这是正确的建筑，

但你有时可能会听到 can

在这种模式中使用让我们再看

一个

例子 我会不会做出错误的

决定 我会不会做出错误的

决定

所以说话者又在想

过去的事情，

或者他们正在和朋友说话

我

可以让我们知道这是一个过去的

表达，因为这个语法是正确的

在这里

，我是否可以

向我们展示这是

演讲者

过去选择做的事情，所以我是否

做出了错误的决定

可能是演讲者

对他自己大声思考 f

或她自己是否有可能我做出了

错误的决定，

或者说话者可能会问其他

人 我是否做出了错误的

决定

，他们期待某种

意见，所以

我们使用这些模式来讨论

可能性，

所以你可能会听到 一些问题

可以

以这种方式使用，但请记住，这些

问题与我们

讨论过

的这些提议类型的

问题

有点不同 可以在不真实的

情况下

使用，我们可以使用很多模式，

但我只想介绍

几种非常

简单的方法，我们使用它，

所以我已经做了这个非常简单的

um 对 if 子句和主子句

，我在这里有主子句，

所以要小心的是，当

你在做

你的虚幻陈述时，你正在使用

这个

if something 主子句

something something 模式

确保你的can

在你的主子句中我们不在

if子句中使用can，所以没有可能在

这里

你的情态动词一般不要把

它们放在if子句中

把它们放在主句中，这样就

意味着like will won 可能

所有这些词也可能将它们放在您的主

句中，

所以我们在不真实的情况下使用了一些不同的模式，

所以我想谈谈这两个它们

有一些具有挑战性的语法

所以让我们来看看

第一个 如果我中了彩票

我可以买房子 如果我中了彩票

我可以买房子 这是我的 if 条款

如果我中了彩票

逗号我可以买房子 所以这里是

can

so could 用来谈论这个

不真实的情况，所以我们知道这不是

真实的，

因为如果就在这里，那

意味着我没有中过彩票

也许我们会因为

这是一种游戏而获得大奖

如果我中了彩票，无论如何都要赌博，这意味着我没有中

过彩票，但如果我中了彩票，

我可以买房子，所以这

可能反映了这个可能性点，

或者你也可以将其视为

残疾点，

但这意味着 我

可以，

所以我有很多钱，所以

可以买房子，所以我们用

can来反映如果我中了

彩票，

我可以在这里买房子，

所以我们不使用can在这种情况下

我们 使用 can 因为这是一个不真实的

情况

我们不使用 this can 来谈论

这些不真实的情况 请

在此处使用 can let's 在这里升级

更具挑战性的

语法 今天早些时候

我们本来可以去电影院的

我们本来可以去电影院的

所以这是一个非常难以理解

的句子 让我们看看我们

今天早些时候是否比我们更早完成了工作所以我们

完成了 ed 在

晚上 8 点工作，但如果我们

已经完成，那么这是指

过去的

动作，如果我们完成了工作，

或者如果我们

在下午 5 点完成了工作，例如

早些时候我们完成了，我们实际上在 8 点完成了，

但如果我们更早完成了

可能 5 we could have going to the cinema

so could have going 这种用法 can

指的是过去的一项活动

在这种情况下去电影院，但

如果我们提前完成工作，如果我们提前完成工作

，例如

下午 5 点在那种不真实的情况下

没有发生，我们本来可以去

电影院

，所以我们使用

这些句子用来谈论

过去没有发生的所有这些事情，

但我们只是想梦想它，所以

这是我们如何使用

can 和再次使用 could 在这里 not

我们可以做一个过去式 exa 的例子 mples

或过去时模式，而不是使用

have

加上动词的过去分词形式，

所以这又是一个具有挑战性的语法

点，但这是我们经常用来

梦想过去的情况，好吧，

让我们以第五点结束本课

所以我想回到第二点，

我们谈到了使用

can 和 could 提出请求和

提供

您可能听到的另一件事是使用

can't

和 can't 提出建议，

所以您会注意到所有这些都使用

否定

所以这里的不同之处

在于，当你使用我们

在第二点中谈到的积极形式时，积极形式听起来

更像是一个请求

，当你使用消极形式时，就像你想要一些东西一样，

虽然它就像你正在给予你正在给予的

东西 一个建议，

所以使用罐头更像是

你在提取

信息，或者你在提取

一些东西

或者不能在

与我们使用 can

和 could 听起来更礼貌的方式相同

，我们经常将它配对，我们经常将它

与就像 a 是修饰符一样

它改变

感觉听起来更简单或更

温和，就像只是一个简单 建议

只是一个小建议，

所以你不能，例如，你

在这里很常见，

正如我在这些模式中谈到的，

但我们可以使用他她他们我们等等，

嗯，加上现在时，嗯

，现在时，

嗯句子我们使用的建议

这里的现在时动词 forcould we can't we can't talk

again now time situation or we can

Imagine as we did here we can想象

过去时的情况

用can't加上过去分词动词形式来做，

就像我们在这里做的那样，这样的一些例子，

你不能早点

离开，你不能早点离开，所以

总是迟到的人，例如，

你不能早点离开 你可以

删除

没关系 你不能早点离开 但只是软化

它就像

这是一个小建议 你

不能早点离开

另一个 你不能打电话

确认

你不能打电话确认这是一个

小建议，

所以听起来更有礼貌，因为

我们使用can't here

finally could you have created

a more budget for the project

你是否已经为项目创建了更大的预算，

所以这是另一个过去时态，

所以 我们又在这里做梦了，

所以你不能创造吗？向我们展示

这是过去的

事情，有人做过听众这样做，

所以演讲者创造了或抱歉

听众

为演讲者所说的项目制定了预算，

你不能创造吗？ 为项目提供更大的

预算

，所以这是给出一个

建议，

或者更确切地说是演讲者

对听众过去做出的选择或决定的看法，

所以我们使用这些负面形式来给出

建议，给出建议，给出

意见 h 没有太多的要求或提议

好的 所以这是很多

信息 很多不同的使用方式 can 和

could 并且还有一些模式

在本课中我没有讨论很多模式

所以你可以

尝试我认为 使用这五点

也许

可以更好地理解 can 和 can 的

不同用途，

因为你在听和

读的时候也是如此，所以我希望这

对你再次有帮助，
