Oh.

Hello.
3
I should have prepared for this lesson, and I guess now I don't know what to say.
4
Whoops.
5
Martin, you could have at least warned me.
6
Now what are we going to do?
7
I would have done it, but I was just so busy.
8
I could have done it if you told me.
9
Don't you have some notes or something we can use?
10
I had some notes, but I can't find them.
11
Well, think about it.
12
Where could they be?
13
Not sure.
14
I could have left them on the bus.
15
I should have never agreed to do this video.
16
Hi, I'm Martin.
17
Welcome to Oxford Online English!
18
In this lesson, you can learn how to use would have, should have, and could have.
19
These verbs would, should, could, etc. are modal verbs, so they don't have past forms like normal verbs do.
20
Instead, you can talk about the past by adding have plus a past participle after the verb.
21
In this lesson, you'll learn to use those modal verbs to talk about the past in English, what they mean, and how they're different.
22
Sometimes you have moments when your life could go in very different ways.
23
For example, maybe you take an important exam, and your result decides where you can go to university.
24
Maybe you're thinking about moving to another country.
25
Do you stay where you are, or do you leave?
26
Perhaps you're in a relationship, and things aren't going so well.
27
Do you stay and try to make it work, or do you move on?
28
Life is full of these important moments and decisions.
29
Try to think of something like this from your past.
30
Now ask yourself.
31
You made the choices you made.
32
You passed the exam or you failed it.
33
You moved to another country or you didn't.
34
That's reality, but what if things had gone the other way?
35
This is the imaginary past.
36
You're imagining a different version of the past.
37
You're asking yourself questions like, what if I had worked a bit harder and passed that exam?
38
What if I had taken that job and moved to Italy?
39
What if I had told her how I feel?
40
This is where you use would have.
41
Use would have to talk about the imaginary past.
42
For example, if I had got better exam results, I would have got into Harvard.
43
I wouldn't have met my wife if I had moved to Italy seven years ago.
44
If I hadn't forgotten my pen that day, I wouldn't have asked to borrow yours, and we wouldn't have become friends!
45
Think about your important moment from the past when your life could have gone in two very different directions.
46
What would have happened if things had gone the other way?
47
So you can use would have to talk about the imaginary past.
48
What about our other verbs?
49
Where do you suppose they are?
50
I don't know.
51
They're usually so reliable.
52
I guess they could have mixed up the date.
53
Shall we try calling them again?
54
We can't wait forever.
55
When will it be ready?
56
I think next Thursday.
57
You said you'd have it finished by the end of this week.
58
Now what am I going to do?
59
Sorry.
60
You could have told me sooner that you weren't going to finish on time.
61
Doctor, is it serious?
62
No, it's just a scratch.
63
But be more careful next time.
64
You could have really hurt yourself.
65
You can also use could have to talk about the imaginary past.
66
If I'd had more time, I could have finished everything.
67
He could have won it if he hadn't slipped at the start.
68
When you use could have to talk about the imaginary past, you're talking about possibilities.
69
We're talking about opportunities and chances which you didn't have in reality,
70
but in your imaginary version of the past, you would have had these chances.
71
However, could have can also have different meanings.
72
Let's look!
73
Here you saw three more ways to use could have.
74
that you can go back and review the dialogues if you need to.
75
Can you explain how could have is used in each of these dialogues?
76
Could have can mean that you aren't sure about something in the past.
77
You're talking about a possibility.
78
They could have mixed up the date.
79
I've lost my keys.
80
I could have left them at work. Where are they?
81
I guess they could have missed the train.
82
In these examples, you aren't sure about something that happened in the past.
83
You use could have to make a guess about what happened.
84
You can also use could have to criticise someone.
85
You could have told me sooner.
86
You could have tidied up a bit.
87
You could have worn something a bit nicer.
88
In these examples, you want to criticise the other person for something they didn't do.
89
Finally, you can use could have to mean that somebody was lucky to avoid a bad situation in the past.
90
It's just a scratch, but you could have really hurt yourself.
91
We were really late, and we could have missed our plane, but luckily we just made it!
92
Let's review quickly.
93
Could have has four different meanings. Can you remember them?
94
You can use could have to talk about the imaginary past, to guess about something in the past which you aren't sure about,
95
to criticise someone for something they didn't do, and to say that someone was lucky to avoid a bad situation.
96
Next, what about should have?
97
You just saw that could have can be used to criticise someone.
98
Could have is similar, but you can use it in a wider variety of ways.
99
Like could have, you can use it to criticise something that someone didn't do in the past.
100
You should have called me like you promised.
101
He should have checked the recipe before he started cooking.
102
They should have practised penalties before the match.
103
You can also use it to criticise something that someone did.
104
You shouldn't have drunk so much at the wedding.
105
She shouldn't have left everything to the last minute.
106
You can even use it to criticise yourself.
107
If you regret something which you did in the past, I should have realised what was going on.
108
I shouldn't have said that.
109
You can also use should have to apologise to someone.
110
If you say, I shouldn't have said that, you're admitting that you made a wrong choice and that you regret it.
111
This is the most common use of should have, criticizing others or yourself and talking about things you regret in the past.
112
However, it has one more meaning.
113
Look at three examples.
114
Can you work out what should have means here?
115
Here, you use should have to talk about something which you expected to happen, but it didn't happen.
116
They should have been here by now means that you expected them to have arrived before now, but you're still waiting.
117
It should have been ready an hour ago means that you expected everything to be ready earlier.
118
Maybe you're cooking something, and it's taking much longer than you thought it would.
119
The plane should have landed at 7.30.
120
Means you expected the plane to land then, but it didn't.
121
Probably you mean that the plane is late, and you're still waiting for it.
122
Now, you should have learned two different ways to use should've.
123
Let's practice using would have, could have, and should have together.
124
You should have told me your friends were coming.
125
I would have made some extra food.
126
Sorry, I would have called you, but I had no phone credit.
127
I should have topped up before we went out.
128
What are we going to eat?
129
We don't have much in the fridge.
130
I should have stopped and got a takeaway on the way.
131
Not to worry, we'll order something.
132
Where's the food?
133
I'm so hungry!
134
They should have come by now, right?
135
They're probably just busy.
136
They could have forgotten.
137
They would have called if there was a problem, don't you think?
138
Relax.
139
You should have had a snack when you got in.
140
It'll be here soon. That was delicious!
141
I've never had such a good meal.
142
You could have left some for me.
143
What am I supposed to eat?
144
Oh, I'm sorry.
145
I would have left some if I'd known you'd wanted some.
146
I should have asked.
147
Yeah, you should have.
148
Oh well, there's half a cucumber in the fridge, I think.
149
Look at three sentences from the dialogues.
150
Can you explain what they mean?
151
The first sentence is talking about the imaginary past.
152
It means that if I had known you were bringing guests, I would have made some more food.
153
But, in reality, I didn't know, so I didn't make enough food.
154
The second sentence is talking about something you aren't sure about in the past.
155
Do you remember the situation?
156
We were waiting for our takeaway to arrive.
157
It was late and we didn't know what happened.
158
You use could have here to make a guess about something in the past when you don't know what happened.
159
The third sentence is a criticism, or an expression of regret.
160
If you say this, you mean that you made a mistake in the past.
161
Think back to the dialogues.
162
Did we use should have or could have in any other ways?
163
Look at two more sentences.
164
They should have come by now.
165
It could have left some for me.
166
What do should have and could have mean here?
167
Here should have means that something didn't happen the way you expected.
168
You expected the food to be here by now, but it isn't.
169
Could have is used to criticise something which someone else didn't do.
170
Now, hopefully you understand how to use would have, could have, and should have.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
