【专题一】:can和could的用法
【例1】Can you lift this heavy box (体力)
【解析】表示能力(体力、知识、技能)
【练习】
1.Mary___________speak three languages.(知识)
2. ___________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式;而be able to则有更多的时态。
I’ll not be able to come this afternoon.
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。
【例2】
-----Can I go now
----- Yes, you can. / No, you can’t.
【解析】表示请求和允许。此时可与may互换。在疑问句中还可用could,might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
【练习】
---- ___________I come to see you tomorrow
---- Yes, you___________.
----No, you___________ /I’m afraid not.
【例3】Can this be true
【解析】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。
【练习】
This___________be done by him.
How___________this be true
【专题二】may和might的用法：
【例1】----Might/ May I smoke in this room
---- No, you mustn’t.
【解析】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”。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。
【练习】
----___________I take this book out of the room
---- Yes, you___________. No, you
【例2】He may /might be very busy now.
【解析】表示推测、可能性(不用于疑问句)。might非过去式,它所表示的可能性比may小。
【练习】
1.Your mother___________not know the truth.
2.He ___________very busy now.他现在可能很忙。
【专题三】must和have to的用法：
【例 1】The man___________be our teacher。那个人一定是我们的老师。
【例 2】I___________study hard because of my dream .为了我的梦想我必须努力学习。
【例 3】1.You___________come in time.你必须准时过来
【解析】：must表示必须、必要。表示主观对事物的推测时，意为想必、一定，只用于肯定句中;表推测时，情态动词与动词原形(常为be动词)连用。而have to强调客观需要。
【练习】:
1.Her play is boring, I___________go now.
2.Your mother___________be waiting for you now.
3.I___________go home, because my father is ill.
【例4】---Must we hand in our exercise books today
---Yes, you___________.
---No, you___________.
【解析】：在回答由must引出的问句时，如果是否定的，不能用mustn’t,而用needn’t,don’t have to.must是说话人的主观看法,而have to则强调客观需要。
【练习】:
---Must he go to school now
---Yes, he___________.
---No, he___________.
【专题四】should的用法

三、阅读短文，根据短文内容选择正确的答案。
Long ago, many people lived on farms. Sometimes farmers would need a new barn(谷仓). So they asked their neighbours(邻居) to come and help build it. This was called a barn raising. People from all around came a long way to a barn raising. Usually the whole family got to go.
Everyone worked together to build a barn. It was a lot of hard work because it was a very heavy job to build a big barn. Some people, mostly women or the old, could not help build the barn, but they had other jobs, like watching the children, cooking all the food. Everyone on the farm was busy.
Why neighbors helped at a barn raising First, people wanted to help those people in need. If they could help, they would. Their help was a gift to their neighbors. Also, building a barn was hard work. The job was easier when more people came together. Farmers loved to travel a long way to help their neighbours with the hard jobs. Finally, and the most importantly, the neighbors knew that they might need a new barn someday. If they helped a farmer build a barn, the farmer would return the same work someday.

A. Farmers lived far away.
B. Farmers asked the neighbours to come and build a new barn.
C. Farmers came a long way to build a new barn.
( )2. Who would go for a barn raising

( )4. Why did neighbours love to help at a barn raising
A. They could help each other with big heavy jobs.
B. It’s an easy job.
C. They wanted to meet friends.
( )5. What is NOT right about a barn raising
A. People wanted to help those people in need.

C. Building a barn was easier when more people came together.
四、阅读短文，判断下列句子是否符合短文内容，如符合，写“T”，否则写“F”。
Being polite is very important. If you are polite to others, they will be polite to you.
In English there are many workds to show you are polite. Many visitors don’t know when to use “please”. When they go into a cafe and say “A coffee.” or “I want a coffee.” These might be OK for the English people. But they can be very impolite to an English ear if you are a visitor. So adding a simple “please” would make it better. “A coffee, please.” Or “I would like a coffee, please.” will make you a polite visitor.
In fact, you can be even more polite: “Sorry, could you tell me the way to Oxford Street, please ” Sorry, could you tell me your name again, please ” It’s very common to start a request(请求) with the word “sorry”.
If you ask for help, try “I’m sorry to bother you.” or “But could you possibly help me, please ” And you might say to a friend “Hey, John. Lend(借) me＄100, will you ” But you couldn’t say this to somebody you do not know well.
( )1. It’s OK for a visitor to say “I want a coffee.” when they are in a cafe.
( )2. “I would like a coffe, please.” is a polite way to say.
( )3. “Sorry, could you tell me your name again, please ” is an impolite way to say.
( )4. In England, people seldom start a request with the word “sorry”.
( )5. You can say to a friend “Hey, Xiaoling. Lend me 100 yuan.”
