Step 1 Revision

Review the usage of the modal verb in Unit 1.

Step 2 Modals(2)

Activity 1

1.       T asks Ss to read the sentences in the box in Activity 1 and answer questions.
2.       Ss figure out the levels of possibility indicated by different modals by analysing the sentences in Activity 1.

Questions:①What do the words in blue indicate: an order, a request, ability or possibility?

②Will the meaning of sentence (a) change it we replace “could” with “must”?

③What happens if we change “must”and “might” in sentence (b) and (c) into “could”?

3.Ss share their answers with class.

Q1:The words in bold indicate possibility.

Q2 If we replace "could" with "must", the meaning of sentence (a)will change. It means the speaker is quite sure about the statement. If we replace"could"with "might", the meaning of sentence (a) will remain more or less the same. "Could” and "might" in affirmative sentences have a similar meaning when indicating possibility.

Q3.If we change"must" in sentence (b) into “could", it means the speaker is not sure about the statement, and it's only a possibility. If we change "might" in sentence (c) into "could", it means it's impossible for the children to receive their presents.

4.T asks Ss to read the passage again and find out more sentences with modals and figure out the usage of these modals.

The children must have been very excited as they opened it.

The children could have been very excited as they opened it.

… they might not receive their presents if they were not good.

… they could not receive their presents if they were not good.

Step 3 Summary

情态动词表示推测的具体用法如下

情态动词+动词原形

1)can+动词原形

A.用于肯定句,表示客观可能性,意为“可能”,即从理论上看是可能的,但不一定会发生。例如:

As a human being, anyone can make a mistake(作为人类,任何人都有可能犯错。)

B.用于否定句或疑问句,表示对现在的动作或状态进行主观的猜测,意为“可能”,或表示惊异、怀疑等态度。例如:

a. He can't have a lot of money(他不可能有很多钱。)

b Can it be that it was l, not he, who was mistaken?(难道是我弄错了,而不是他弄错了?)

2)may+动词原形,表示主观的推测,意为“或许”,用于肯定句和否定句均可。例如:

a. He may be very busy now(他现在可能很忙。)

b. He may not be at home(他可能不在家。)

注意:表示可能性时,can't语气较强,表示“不可能”; may not语气较弱;表示“可能不,或许不”。3) might+动词原形,表示推测,意为“可能",可以指过去的情况,也可以指现在的情况,但语气比may更加不肯定。用于肯定句或否定句均可。例如:

a. They might have a lot of work to do now but I'm not sure.

(他们现在可能有很多活儿要干,不过我不确定。b. She was afraid they might not like the idea(她担心他们可能不喜欢这个想法。)

4)could+动词原形,意为“可能”,可以指过去的情况,也可以指现在的情况,语气缓和。多用于否定句或疑问句。例如：

a. He looks young. He couldn't be over 50.(他看起来很年轻,不可能超过50岁。)

b. Could it be true(那可能是真的吗?)

5)must+动词原形,表示猜测,意为“准是,一定”,通常用于肯定句。例如：

a. This must be your room(这一定是你的房间。)

b Look at his new car. He must have a lot of money(瞧他那辆新车。他肯定很有钱。)

情态动词+完成式

1)must+完成式,表示对已发生情况的推测,通常用于肯定句。例如:

She must have gone home(她肯定已经回家了。)

2)can+完成式,表示对已发生情况的推测,主要用于否定句或疑问句。例如：
