【重点难点解析】
1. 舒特一家正在洗衣服。
误：Shutes are doing the washing.
正：The Shutes are doing the washing.
析：英语中在表示姓氏的复数形式前加定冠词the，指一家人或夫妇俩。
2. 今天天气怎么样?
误：What's a weather like today?
正：What's the weather like today?
析：weather(天气)一般用作不可数名词，不能用不定冠词修饰，如表示特指，可用定冠词，也可用形容词来修饰。
3. 汤姆是你个子最高的弟弟。
误：Tom is the your taller brother.
正：Tom is your tallest brother.
析：在“the+形容词最高级”结构中，the不能省略，如形容词有指示代词、物主代词、名词所有格修饰时，定冠词就必须省去。另外，副词最高级前的the可以省略。如：Which day do you like best?
4. 她是两个女孩中年龄较小的。
误：She is younger of the two girls.
正：She is the younger of the two girls.
析：比较级前一般不使用定冠词，但如果给定了比较范围仅有两个比较对象时，就要加定冠词。
5. 我们正在欣赏一部非常精彩的电影。
误：We are seeing the most wonderful film.
正：We are seeing a most wonderful film.
析：此句不表示比较， 译为“很、非常”。
6. 老师的桌子在教室的前面。
误：The teacher's desk is in front of the classroom.
正：The teacher's desk is in the front of the classroom.
析：in front of指在某人或某物范围之外的前面；in the front of指在某一物体范围之内的前部。
7. 第一课。
误：The lesson one.
正：Lesson one.
析：基数词用在名词后起序数词作用时，所构成的词组不用定冠词。
另外，还需注意“有无冠词意不同”。如：
young年轻的，the young年轻人；in hospital生病住院，in the hospital住在具体哪家医院，go to bed 上床睡觉，go to the bed到床那儿去；go to school 上学，go to the school 到学校去；other指不定范围中的另一个，the other指两者中的另一个。

4. -Will you please us a story, Miss Gao?

A. make B. let C. ask D. keep
8. The ticket is on the floor. Please . (吉林)
A. pick up it B. pick up them
C. pick it up D. pick them up
答案及简析：1. A。stop to do sth. 意为“停下来去做某事”。let后接不带to的不定式，故C错了。2. D。“Why not+动词原形”意为“为什么不……? ”。3. D。tell sb. not to do sth. 结构意为“叫某人不要做某事”。4. C。这四个动词中，只有tell后可接双宾语；“用某种语言说某事”应用“say sth. in+语言名词”表达。5. A。“听音乐”即listen to the music。6. C。根据情景，只有look around(环顾四周)符合题意。7. C。ask sb. to do sth. 意为“请某人做某事”。let，make的宾语后用不带to的不定式作宾补，keep后应接v-ing形式。8. C。指代前句中的单数名词ticket时，显然只能用it，故排除B、D；pick up的宾语为代词时，代词只能位于动词后、副词前。

D。回答表示有无必要的must问句时，否定回答用needn't。7. D。前句中的needs明显属 行为动词，不是情态动词，故排除A、B。8. C。Let's…shall we? 意为“让我们……好吗? ” 9. D。have(has)to意为“必须”，其否定式用don't/doesn't have to，故本题变反意疑问句时应先排除A、B。10. B。enjoy后接v-ing形式。
【阅读分析点拨】
Last year I went to America. I stayed there for half a year. I found most Americans had three meals(餐) a day. They had breakfast in the morning, a light lunch at noon, and a big dinner in the evening. They often had breakfast and lunch in a hurry, but they had more time for dinner. Americans usually drank a lot of water, a lot of milk, and a lot of coffee, but they did not drink much tea.
Some Americans liked to have meals in a cafeteria(自助餐厅). They could go there for breakfast, lunch, or dinner. In the cafeteria a person(人) first took a knife, a fork(叉)， a spoon(勺), and a napkin(餐巾). Then he went to a long counter( 柜台). He could see all the food there. He chose his meal and put it on his big plate. Then he paid (付账)for it and carried his big plate to a table. People liked this self-service, for the meals were not very expensive in a cafeteria; they were more expensive in a restaurant.
