3、ield.The police drove the crowds back.I drove my car into the garage.B1 home  2 houses  3 house  4 home3多項選擇題答案1. c根據(jù)課文第3-4行Last year, however, it came into use, 只有c. came into use recently 比較接近課文的實際內(nèi)容，而其他3個選擇都不符課文內(nèi)容。2. d根據(jù)課文第8行but I am determined to stay here, 只有d. has refused to lea

4、ve his house 與課文內(nèi)容相符，其他3個選擇都與事實不符。3. c只有選c. can hear  才能使這個句子同前一句Passing planes can be heard night and day 的含義相同，只是語態(tài)不同。 而其他3個選擇a. can heard, b. can to hear, d. can be heard 都不符合語法，在意思上都講不通。4. d只有d. possible 才能使句子同前一句It couldn't be used then 意思最接近。a. able （能）需要人作主語，本句的主語是it 形式主語;b. allowed（

5、允許）不符合題目的意思， c. impossible（不可能的）與句子意思相反。5. a前面句子Over a hundred people must have been driven away 中的must 表示說話人的一種主觀推測。 b. Im sure(我確信) 語氣比較肯定，不表示推測；c. Certain(肯定的)是形容詞，缺主語和謂語，不符合語法和題目意思。； d. Of course(當然) 表示“肯定”的意思，也不夠準確； 只有a. I think(我想，我認為) 表示推測，所以應該選a. 6. c只有c. are some left 才能使這個句子比較接近前一句I am one

6、 of the few people left,因為few(少數(shù)幾個)同some(一些)意思比較接近, a. are none left(一個沒剩)不等于the few. b. is one left(剩下一個)也不等于the few; d. are a lot left(剩下很多)與the few 意思相差懸殊. 所以選c.7. b這是一個疑問句，需要主謂倒置語序。 a. have you been offered, C. you have offered, d. they offered you 這三個選擇都是陳述句語序，只有b. have you been offered 是疑問句語序，

7、因此選b.8. b只有b. give(給)出同前面的動詞offered 詞意思相近， 而a. serve(服務，服侍)， c. take(拿，帶)， d. make(做，制造) 這3個選擇都與offered 意思不同。9. ab. number 只能修飾人，不能修飾不可數(shù)名詞money, c. some不符合語法，意思不成立； d. piece 只能修飾不可數(shù)名詞，但是不能修飾money.只有a. amount(很多，一大筆)表示金額，可以修飾money. a large amount of很多，一大筆,表示金額，a number of是只用于可數(shù)名詞10. d只有d. am going to 才比較接近前一句I am determined to stay here.(我決定留在這里)的含義。其他3個選擇中：a. am will to 不符合語法； b. want to(想要)與be determined to 的含義有些差距；c. may (可以) 詞意思更不正確。11. c只有c. Perhaps 才能與前一句中的they are probably right(他們可能是對的)意思相吻合，表示“可能”，“也許”（不肯定的推測）， 而a. Of course(當然)， b. Its certain( 肯定)， d. Its sure(一定) 這3
