Unit 3  Language in use

1. can, could

1)表示能力(体力, 知识, 技能) , 常用情态动词can和could表达。

  Can you lift this heavy box? (体力)

  Mary can speak three languages. (知识)

  Can you skate? (技能)

此时可用be able to代替。can只有一般现在时和一般过去时；而be able to则有更多的时态。

I’ll not be able to come this afternoon.    (一般将来时)

当表示“经过努力才得以做成功某事”时应用be able to, 不能用can。如：

He was able to go to the party yesterday evening in spite of the heavy rain. 

2) 表示请求和允许

     ---Can I go now?

     ---Yes, you can. / No, you can’t.

    此时可与may互换。在疑问句中还可用could, might代替，但could, might 并不表示过去式，只是语气更委婉。它们不能用于肯定句和答语中。

    --- Could I come to see you tomorrow?
    --- Yes, you can. (No, I’m afraid not.)

3) 表示客观可能性 (客观原因形成的能力)。

    They’ve changed the timetable, so we can go by bus instead.

    This hall can hold 500 people at least.

4) 表示推测 (惊讶、怀疑、不相信的态度) ，用于疑问句、否定句和感叹句中。

    Can this be true?

    This can’t be done by him.

    How can this be true?

2. may, might

1) 表示请求和允许。might比 may语气更委婉，而不是过去式。否定回答时可用can’t 或mustn’t，表示“不可以，禁止”。 例如：

---- Might/ May I smoke in this room?  ---- No, you mustn’t.

 ---- May/Might I take this book out of the room?
---- Yes, you can. (No, you can’t / mustn’t. )

 用May I...？征徇对方许可时比较正式和客气，而用Can I...？在口语中更常见。

2) 用于祈使句，表示祝愿。 例如：May you succeed!

3) 表示推测、可能性 (不用于疑问句)。might不是过去式，它所表示的可能性比may小。 例如：He may /might be very busy now.

    Your mother may /might not know the truth.

3. must, have to

 1) 表示必须、必要。例如：You must come in time.

    在回答引出的问句时, 如果是否定的, 不能用mustn’t (禁止, 不准)，而用needn’t, don’t have to (不必)。

---- Must we hand in our exercise books today?
---- Yes, you must.
---- No, you don’t have to/you needn’t.

2) must是说话人的主观看法，而have to则强调客观需要。must只有一般现在时，have to 有更多的时态形式。 例如：
    His play isn’t interesting, I really must go now.

    I had to work when I was your age.

3) 表示推测、可能性 (只用于肯定的陈述句)   例如：

     You’re Tom’s good friend, so you must know what he likes best.

     Your mother must be waiting for you now.

4. shall和should

1) shall 征求对方意见

 Shall we go out for a walk?\What shall we drink?

2) should 劝告﹑义务﹑责任

We should protect our environment.

You should do it better next time.

5. will, would

1) 表示请求、建议等，would更委婉。例如: Will / Would you pass me the ball, please?

2) 表示意志、愿望和决心。例如: I will never do that again.\They asked him if he would go abroad.

3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式，且没有“现已无此习惯”的含义。

     During the vacation, he would visit me every other day.

     The wound would not heal.

4) 表示估计和猜想

    It would be about ten o’clock when she left home.

6. should, ought to

1)should, ought to表示“应该”，ought to 表示义务或责任，比should语气重。

   I should help her because she is in trouble.

   You ought to take care of the baby.

2) 表示劝告、建议和命令。should, ought to可通用，但在疑问句中常用should。

     You should/ought to go to class right away.

     should, ought to (客观),  must(主观)

四、阅读单选

On April 2, we said goodbye to Tiangong I, China's first space lab. According to the China Manned Space Agency（中国载人航天）, Tiangong I re-entered the Earth's atmosphere（大气层）and some of its debris（碎片）fell into the South Pacific Ocean.

There are many spacecraft（宇宙飞船）that are still in orbit（轨道）above the Earth. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong I.

There are two types of re-entries: controlled re-entry and uncontrolled re-entry.

Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate（计算）the path of the falling spacecraft and its speed. They can guide the spacecraft to fall in a chosen area.

Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.

During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.

22．The debris from Tiangong 1       .

A．fell into the South Pacific Ocean B．fell in western Australia

C．fell in the central part of the US D．fell into the North Pacific Ocean

23．When the spacecraft finishes its trip, it will       .

A．burn up and disappear B．speed up and fly back to the Earth

C．enter another orbit and stay in space D．re-enter the Earth's atmosphere

24．From the passage, we know there are        types of re-entries.

A．one B．two C．three D．four

25．Which of the following is TRUE about the US space station Skylab?

A．It came back in a controlled re-entry.

B．Some people were hurt by its debris.

C．Parts of it fell in western Australia.

D．It was directed to fall into the ocean.

26．This story most probably comes from       .

五、短文汉语提示填空
