1. _______ born in China, the boy was brought up in the USA.

　　A. Although B. Since C. As D. When

　　【精析】 A 分析句意可知，本句應(yīng)為although引導(dǎo)的讓步狀語從句，表示“雖然，即使”的意思。因為主從句主語和謂語一致，所以從句中although后省略了“the boy was”。although與but不能同時出現(xiàn)。since和as均引導(dǎo)原因狀語從句，as也可引導(dǎo)讓步狀語從句，但是需用倒裝形式;when引導(dǎo)時間狀語從句。

　　2. _______ is known to all, haste makes waste.

　　A. What B. That C. As D. Which

　　【精析】 C 常用搭配“As is known to all”意思“眾所周知”，是as引導(dǎo)的非限制性定語從句，as指代逗號后面的整個主句，并在從句中充當(dāng)主語。如：As is known to all, war is serious.眾所周知，戰(zhàn)爭是殘酷的。

　　3. That is the very old woman _______ house was burned down last night.

　　A. which B. her C. of whom D. whose

　　【精析】 D whose為關(guān)系代詞，指人，是先行詞old woman的所有格，在從句中充當(dāng)house的定語。

　　4. Hardly had he finished his speech _______ the audience started cheering.

　　A. than B. then C. when D. as soon as

　　【精析】 C 固定搭配“Hardly...when...”表示“一……就……”，另有“no sooner...than”和“Scarcely...when”均表示相同的意思。

　　5. _______ the book, he found out some answers to this question.

　　A. As he reading B. At his reading

　　C. As reading D. On reading

　　【精析】 D on doing意為“一……就……”。此處的on相當(dāng)于as soon as,引導(dǎo)狀語從句。表示從句中的動作的時間比主句中動作的時間稍提前一點。

　　6. The spacecraft will send back _______ on surface winds and temperatures.

　　A. many new information B. some new information C. a new information D. a few new information

　　【精析】 B information為不可數(shù)名詞，所以不能用many、a和a few修飾，排除A、C、D項。some既可修飾可數(shù)名詞又可修飾不可數(shù)名詞，故選B項。

　　7. The reason for my refusal is _______ you’re unreliable.

　　A. because B. that C. due to D. for

　　【精析】 B 在復(fù)合句中做表語的從句叫做表語從句，它位于主句中的連系動詞之后�？捎脧膶龠B詞that,whether,as if引導(dǎo)。所以本題應(yīng)選B，其余選項不引導(dǎo)表語從句。

　　8. He came all the way to China for promoting friendship _______ for making money.

　　A. other than B. instead C. apart from D. rather than

　　【精析】 D other than:除了;instead：作為替代，反而;apart from：除……以外;rather than：而不是。

　　9. If you don’t mind, I _______ do my homework than play cards with you.

　　A. had better B. would rather C. prefer D. would like

　　【精析】 B “would rather...than...”意為“寧可(愿)……而不要(愿)……”用以表達(dá)主觀的意愿，強調(diào)經(jīng)過選擇后做一件事，而不愿做另一件事。had better表示“最好”，后跟動詞原形;prefer sth. to sth.表示“喜歡……而不喜歡……”would like to do sth.表示“寧愿、愿意做某事”。

　　10. No one, except his two best friends, _______ where he is.

　　A. know B. to know C. knows D. knowing

　　【精析】 C 當(dāng)主語部分為“主語+后置定語”時，謂語動詞只看主語，不看后置定語部分。引起這種后置定語的單詞有：with, along with, together with, as well as, except, besides等。由于本句主語為不定代詞no one,所以謂語動詞應(yīng)用第三人稱單數(shù)形式，與主語保持一致。

　　11. _______, you would have seen your favorite movie star.

　　A. If you arrived earlier B. If you had arrived earlier

　　C. Unless you arrived earlier D. Unless you had arrived earlier

　　【精析】 B 本句是If引導(dǎo)的條件狀語從句表示對過去情況的假設(shè)。其形式為從句：if+主語+had+過去分詞+其他，主句：主語+should/would/could/might+have+過去分詞，根據(jù)題中主句的結(jié)構(gòu)可知選B。

　　12. The driver’s carelessness _______the death of three passengers.

　　A. resulted from B. resulted in C. came across D. came about

　　【精析】 B result from:因為，由于;result in:導(dǎo)致，致使;come across:(偶然)遇見，被理解;come about:發(fā)生。根據(jù)句意選B。

　　13. In England,tea_______with milk and sugar.

　　A. is serving B. is served C. serves D. served

　　【精析】 B serve sth.with sth.意為“某物搭配某物一起提供”。本句中tea(茶)是被提供的，因此用被動語態(tài)。

　　14. Written in great haste,_______.

　　A. the secretary made a lot of mistakes in the report

　　B. there were a lot of mistakes in the report

　　C. we found a lot of mistakes in the report D. the report was full of mistakes

　　【精析】 D Written in great haste 在本句中作獨立主格，其邏輯主語應(yīng)與主句的主語保持一致。因為用的是被動語態(tài)。Written，很明顯其主語應(yīng)該是report,故主句主語也應(yīng)該是report,用排除法可知答案為D。

　　15. It’s suggested that each one of us_______the training classes for English.

　　A. takes part in B. take part in

　　C. took part in D. would take part in

　　【精析】 B 在 It’s suggested/advised/demanded...表建議、要求、命令等意義的詞引導(dǎo)的主語從句中，謂語需用should+動詞原形，should可以省略，故選B。

　　16. The only thing _______interests me is the progress of my students.

　　A. what B. that C. which D. it

　　【精析】 B 定語從句中的先行詞有only、形容詞最高級等詞修飾時，引導(dǎo)詞要用that,故選B。

　　17. People do not realize the importance of good health _______ they have lost it.

　　A. until B. when C. since D. as

　　【精析】 A not...until意為“直到……才”，因為句中有not,只能選until。

　　18. If there were no homework at weekends,students would have _______at home.

　　A. the happiest time B. much happiest time

　　C. a more happier time D. a much happier time

　　【精析】 D have a happy time“玩得愉快”，其比較級形式應(yīng)為“have a much happier time”。

　　19. The reason he won the election is _______he is honest and confident of himself.

　　A. why B. what C. that D. which

　　【精析】 C 本句是that 引導(dǎo)的從句作表語，用來對先行詞the reason作進(jìn)一步的解釋和說明。

　　20. Mr.and Mrs.Brown _______ a small restaurant in China Town in New York.

　　A. serve B. start C. open D. run

　　【精析】 D 表“經(jīng)營餐館、公司等”，動詞要用run,故選D。
