【重點難點解析】
1. 舒特一家正在洗衣服。
誤：Shutes are doing the washing.
正：The Shutes are doing the washing.
析：英語中在表示姓氏的復數形式前加定冠詞the，指一家人或夫婦倆。
2. 今天天氣怎么樣?
誤：What's a weather like today?
正：What's the weather like today?
析：weather(天氣)一般用作不可數名詞，不能用不定冠詞修飾，如表示特指，可用定冠詞，也可用形容詞來修飾。
3. 湯姆是你個子最高的弟弟。
誤：Tom is the your taller brother.
正：Tom is your tallest brother.
析：在“the+形容詞最高級”結構中，the不能省略，如形容詞有指示代詞、物主代詞、名詞所有格修飾時，定冠詞就必須省去。另外，副詞最高級前的the可以省略。如：Which day do you like best?
4. 她是兩個女孩中年齡較小的。
誤：She is younger of the two girls.
正：She is the younger of the two girls.
析：比較級前一般不使用定冠詞，但如果給定了比較范圍僅有兩個比較對象時，就要加定冠詞。
5. 我們正在欣賞一部非常精彩的電影。
誤：We are seeing the most wonderful film.
正：We are seeing a most wonderful film.
析：此句不表示比較， 譯為“很、非常”。
6. 老師的桌子在教室的前面。
誤：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指在某人或某物范圍之外的前面；in the front of指在某一物體范圍之內的前部。
7. 第一課。
誤：The lesson one.
正：Lesson one.
析：基數詞用在名詞后起序數詞作用時，所構成的詞組不用定冠詞。
另外，還需注意“有無冠詞意不同”。如：
young年輕的，the young年輕人；in hospital生病住院，in the hospital住在具體哪家醫院，go to bed 上床睡覺，go to the bed到床那兒去；go to school 上學，go to the school 到學校去；other指不定范圍中的另一個，the other指兩者中的另一個。

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
答案及簡析：1. A。stop to do sth. 意為“停下來去做某事”。let后接不帶to的不定式，故C錯了。2. D。“Why not+動詞原形”意為“為什么不……? ”。3. D。tell sb. not to do sth. 結構意為“叫某人不要做某事”。4. C。這四個動詞中，只有tell后可接雙賓語；“用某種語言說某事”應用“say sth. in+語言名詞”表達。5. A。“聽音樂”即listen to the music。6. C。根據情景，只有look around(環顧四周)符合題意。7. C。ask sb. to do sth. 意為“請某人做某事”。let，make的賓語后用不帶to的不定式作賓補，keep后應接v-ing形式。8. C。指代前句中的單數名詞ticket時，顯然只能用it，故排除B、D；pick up的賓語為代詞時，代詞只能位于動詞后、副詞前。

【閱讀分析點撥】
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(自助餐廳). 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( 柜臺). He could see all the food there. He chose his meal and put it on his big plate. Then he paid (付賬)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.
