would语法点大全（语法小课堂Shouldcould）

今天我们继续语法知识啦，相信很多小伙伴都有点疑惑Should/could/Would这三个情态动词到底是怎么区分的呢？那接下来咱们就跟着老师一起来逐个解析哦。

这几个情态动词又称为 “modals of lost opportunity” 因为它们指说话人但愿过去实情不同。

要掌握这几个情态动词的现在完成式

1

首先我们复习一下，情态动词should, could, would的一般规律

1.Should 表建议 (advice)

• If you want to lose weight, you should eat healthy food.

  如果你想减肥，你应该吃健康的食物。

• You shouldn’t spend so much time watching TV.

  你不应该花这么多时间看电视。

• My tooth has been hurting for a week already.

  ---You should go to the dentist.

2.Could 表可能性 (possibility)

• I have the day off tomorrow.

  明天我放假。

• Great! We could spend the day at the beach. Or we could go shopping.

  太棒了！我们那天可以去海边。或者去逛街。

• Could I use your phone, please?（礼貌用语）

  请让我用一下你的电话可以吗？

3.Would 表假设意愿 (willingness)

• If she had more time, she would spend it with her children.

  如果她有更多的时间，她会和孩子们一起度过的。

• They would make a lot of changes if they had enough money.

  如果他们有足够的钱，他们会做出很多改变。

经常用语提建议

• Would you like anything to eat?

• Would you like to see some new pictures?

同样的规律也适用于should have, could have, and would have。

表示对于过去的假设

1.Should Have

过去情况的假设，并且也表示“我应该......”，即“过去那个时候，我应该......”

• I should have left my house earlier.

  我该早点出门。

• I shouldn’t have yelled at you yesterday. I’m sorry.

  我昨天不该吵你吼。对不起。

• You should have studied. You shouldn’t have played video games all weekend.

  你该学习。你不应该整个周末都玩电子游戏。

2.Could Have done

用于描述可能性。即“过去如果怎样/不怎样，现在情况可能有所不同。”

（1）是一种虚拟语气的用法，条件从句是过去完成时，主句could 现在完成时

If I had gone to college, I could have gotten a better job.

如果我上了大学的话，我可能会找到了更好的工作。

（2）Could have 一般与 “if 过去完成时” (If I had gone)连用-这里的条件句是一种虚拟语气的用法。

She could not have been on that flight because I just saw her at work.

她不可能

（3）有时候，could have 也可不接条件句，单独出现。

Are you crazy? We could have gotten into an accident.

3.Would Have

表示对于过去的一种假设。即“过去某种情况可能会不同。” 也经常与表示虚拟if条件句连用。

I would have called, but there was no phone service.

我本来要打电话的，但是没有信号。

I would have loaned you the money, but I didn’t have any.

我本来要借钱给你的，但是我当时没钱。

If we had arrived earlier, we would have caught our flight.

如果我们早点到，我们就赶上飞机了。

4.Would have 比could have 更确定

If I had worked harder,I could have gotten a promotion.

如果我之前工作努力点儿，我可能就升职了。

I got a 58 on the test. If I had gotten two more points, I would have passed.

我考了58分。如果我多考两份，我就通过了。

接下来就是练习环节啦，赶紧来检测下吧：

1. I was really anxious about you. You_________have left home without a word.

2. — I’ll tell Mary about her new job tomorrow.

— You________ have told her last week.

3.I _______ have been more than six years old when the accident happened.

4.If you didn't call me ,I _______have finished my work.
