【重点难点解析】
1. They hit us with their sticks over and over again and put some of us in prison.
他们一再用警棍打我们，还把我们中的一些人关进监狱。
①句中的over and over again=again and again/over and over/repeatedly
②put. . . in prison或put/throw/last/put sb. into prison
把…关进监狱。在prison前不用冠词。比较：
go to prison入狱，蹲监狱
go to the prison 去监狱(也许去看望犯人)
in prison 在狱中，被监禁着
in the prison 在监狱中(也许在监狱中工作)
out of prison 出狱
out of the prison 在监狱外
be taken to prison 被关进监狱
break (out of) prison 越狱
escape from prison 逃出监狱
与此类似的还有：go to school 上学
go to the school 到学校去(可能有事)
be at hospital 在住院
be at the hospital 在医院里(也许工作)
be at table 在用餐
be at the table 在桌子旁边
2. She refused to move and was taken away by the police.
①句中的refuse to do sth. 表示不肯做某事，refuse不可接动名词。也不可接sb. to do sth. , 但可接双宾语。例：
They refused me permission. 他们拒绝了我的请求。
②the police表示警察群体。单数形式，复数概念，动词用复数形式。在英语中有一些像police这样不以s结尾的复数名词，无单数形式，常见的有cattle, people, police, youth, public等，表达这些词的单数概念要用a cow, a person, a policeman, a young person等 。
3. For years we've been demanding better housing and jobs.
许多年来，我们一直在要求较好的住房和工作。
句中的We've been demanding是现在完成进行时态，表示从过去某一时间开始，一直持续到目前的动作，常用句型为“have/has been+现在分词”。e. g.
I think we should have a rest. We've been working for three hours.
我想我们应休息一会儿。我们一直干了三个小时了。
4. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
我梦想有一天，我的四个孩子将在一个不以他们的肤色，而是以他们的品格优劣来评价他们的国度里。
(1)这是一个复合句，由that引导的从句作dream的同位语。在这个同位语从句中， 有一个由where引导的定语从句，修饰先行词a nation。
(2)judge by意为“以……来判断；以……来看”，其中的by用来说明手段或方式。
(3) not. . . but. . . 意为“不是……而是……”，引出两个对等成份。若连接两个主语，谓语动词的数应和就近一个主语一致。e. g.
①A man should be judged not by his words, but by his deeds.
不应该从言语上而应从行动上去判断一个人。
②Not the teacher but the students are interested in the film.
不是老师而是学生对该电影感兴趣。

【阅读分析点拨】
We walked in so quietly that the nurse at the desk didn't even lift her eyes from the book. Mum pointed at a big chair by the door and I knew she wanted me to sit down. While I watched mouth open in surprise, Mum took off her hat and coat and gave them to me to hold, She walked quietly to the small room by the lift and took out a wet mop. She pushed the mop past the desk and as the nurse looked up , Mum nodded and said, “Very dirty floors. ”
“Yes. I'm glad they've finally decided to clean them, ” the nurse answered. She looked at Mum strangely and said, “But aren't you working late? ”
Mum just pushed harder, each swipe(拖一下) of the mop taking her farther and farther down the hall. I watched until she was out of sight and the nurse had turned back to write in the big book.
After a long time Mum came back. Her eyes were shining. She quickly put the mop back and took my hand. As we turned to go out of the door, Mum bowed politely to the nurse and said, “Thank you”.
Outside, Mum told me: “Dagmar is fine. No fever”.
“You saw her, Mum? ”
“Of course. I told her about the hospital rules, and she will not expect us until tomorrow. Dad will stop worrying as well. It's a fine hospital. But such floors! A mop is no good. You need a brush. ”
1. When she took a mop from the small room what Mum really wanted to do was .
A. to clean the floor B. to please the nurse
C. to see a patient D. to surprise the story teller
解析 这是一道推断题。从妈妈拿起拖布越过护士的视线到告诉作者“Dagmar is fine. No fever. ”这一系列情节中可以断定，C为该题的最佳答案。
2. When the nurse talked to Mum she thought Mum was a .
A. nurse B. visitor C. patient D. cleaner
解析 这也是一道推断题。护士之所以没有拦住妈妈，她一定是以为妈妈是位清扫工。故D为最佳答案。
3. After reading the story what can we infer about the hospital?
A. It is a children's hospital
B. It has strict rules about visiting hours
C. The conditions there aren't very good
D. The nurses and doctors there don't work hard
解析 这仍然是道推断题。妈妈装扮成清洁工正是由于医院有着严格的探视制度，故B为最佳答案。
4. From the text we know that Dagmar is most likely .
A. the story teller's sister B. Mum's friend
C. the story teller's classmate D. Dad's boss
解析 该题的最佳答案为A。从“You saw her, Mum? ”和“…Dad will stop worrying as well. …”这组对话中可以推断出，病人是作者的妹妹。
5. Which of the following words best describes Mum?
A. strange B. warm hearted
C. clever D. hard working
解析 妈妈之所以能成功地躲过护士的监视，在非探视时间内走入病房，正说明了她的聪明。故C为最佳答案。

5)或：It has been more than 20 years since my father joined the Party.
Lesson 74
3. voter, banker, broadcaster, ruler, actor, marcher, listener, builder, keeper, sailor, supporter, organizer

使用情态动词要注意的问题
下面是同学们在使用情态动词时经常出现的问题，也是情态动词中的难点，而且又是近来高考的热点。
一、要注意一些同义、近义的情态动词的区别
1 . 表示可能性的 can't 与 may not 的区别。
can't 常常表示“不可能”、“一定不”，may not 表示“可能不、或许不”。很明显，can't 比 may not 语气强，把握性大。如：
The man standing over there _____ be Jack . He's gone to Hong Kong .
A . mustn't B . can't C . won't D . may not
说话者既然知道“He's gone to Hong Kong”，那么对“The man 不是 Jack”一定满有把握，故正确选项为 B。
2 . 表示“能够”意义的 can 与 be able to 的区别。
凡表示“经过努力、设法做成某事”时不用 can，须用 be able to。如：
The fire spread through the hotel very quickly , but everyone _____ get out . ( NMET97 )
A . had to B . would C . could D . was able to
句意为：大火弥漫整个旅馆，但人位学是设法逃了出来。故正确选项为D。
3 . 表示“不能”意义的 can't 与 mustn't 的区别。
can't 表示“不能”，是指无能力；mustn't 表示“不能”则指的是“禁止，不允许”。在口语里，can't 也可表示“禁止，不允许”，但语气不如 mustn't 强。如：
( 1 ) 他年纪小，不能上学。
【 正 】He is so young that he can't go to school .
( 2 ) 里边正在开会，不能吵闹。
【 正 】There's meeting inside . You mustn't make any noise .
【 误 】There is a meeting inside . You can't make any noise .
二、要注意几个使用的特定范围
1 . 表示推测时，can 不能用在肯定句中 ( 但 could 能 ) ；may 和 might 不能用在疑问句中。如：
( 1 ) Peter _____ come with us tonight , but he isn't very sure yet . ( MET93 )
A . must B . may C . can D . will
句意为：Peter 有可能同我们一块儿来，但还不肯定。正确选项为 B。
( 2 ) _____ it be a sunny day tomorrow?
A . Can B . May C . Shall D . Should
句意为：明天可能是睛天吗?正确选项是 A。
2 . 作为情态动词，need 和 dare 不能用在肯定句中 ( 条件状语从句除外 ) 。肯定句中，须把它们用作实义动词，后接带 to 的不定式。如：
【 误 】We need hold a meeting to discuss the matter .
【 正 】We need to hold a meeting to discuss the matter .
【 正 】If you need hold a meeting to discuss the matter , I'll give you a help .
3 . 在回答由 could 和 might 引起的表示请示的一般疑问句时，不能用 could 和 might ( 应分别用 can 和 may ) 回答。如：
- Could I borrow your dictionary?
- Yes , of course you _____ . ( MET92 )
A . might B . will C . can D . could
正确选项为 C。
三、要注意一些“形意不一致”的现象
1 . 过去式 could 或 might 后接动词原形可以表示对现在或将来 ( 不是对过去 ) 的推测。如：
I'm afraid it _____ snow tonight .
A . can B . should C . might D . must
2 . may ( not ) 和 can't 后接动词的完成式，表示对过去 ( 不是对现在或将来 ) 的推测。如：
- There were already five people in the car but they managed to take me as well .
- It _____ a comfortable journey .
A . can't have been B . couldn't be C . mustn't have been D . shouldn't be
四、要注意情态动词的常用形式的反常使用。
1 . should 和 ought to 后接动词原形，常表示“应该……”；但也可用来表示推测，意为“想必会……”。如：
( 1 ) It's nearly seven o'clock . Jack _____ be here ar any moment . ( NMET95 )
A . must B . need C . should D . can
句意为：“快七点钟了，想必杰克随时会到的”。正确选项为 C。
( 2 ) - When can I come for the photos? I need them tomorrow afternoon .
- They _____ be ready by 12∶00 . ( NMET98 )
A . can B . should C . might D . need
句意为“ - 我什么时候来取像片呢?我可是明天下午需要这些像片。”“ - 像片想必会在 ( 明日中午 ) 十二点以前洗出的。”正确选项为 B。情态动词表示推测，语气由强到弱的是：must ( 一定会 ) →ought to / should ( 想必会 ) →can / could ( 可能 ) →may / might ( 也许，或许 ) 。
2 . could 后接完成式常表示“ ( 过去 ) 可能……”，但也可用来表示责备语气，意为 “过去 ) 本来能够……， 而实际上却未…… ”。如：
- We could have walked to the station ; it was so near .
- Yes . A taxi _____ at all necessary . ( NMET92 )
A . wasn't B . hadn't been C . wouldn't be D . won't be
该题虽是一道考查动词时态的考题，但从“We could have walked to the station”可知，实际不是步行去火车站的。结合下句可知是坐了出租车去的，时间是过去，故正确答案是 A。
