新概念英語第二冊(cè)課后習(xí)題Lesson 48
    1. c
    根據(jù)課文第3-4行 I tried to say something, but my mouth was full of cotton wool 可判斷只有c. There was something in his mouth 符合課文的真實(shí)情況,這也是作者不能講話的原因,其他3個(gè)選擇都不是原因,所以只能選c.
    2. b
    根據(jù)課文第8-10行I suddenly felt very worried,…when the dentist at last removed the cotton wool… I was able to tell him that he had pulled out the wrong tooth 可以判斷b. he thought the dentist had pulled out the wrong tooth 是作者著急的原因,其他3個(gè)選擇都不是他著急的原因,所以選b.
    3. c
    只有選c. cannot 才能使句子同前一句It is impossible for him to answer.(他是不可能回答的)意義相同,所以c.是正確答案.a. might not 與d .may not 都不符合題目意思. b. could not 時(shí)態(tài)不對(duì).
    4. b
    本句是將前一句中表示命令請(qǐng)求的間接引語變成了直接引語(祈使句)。
    a. To rest 是動(dòng)詞不定式,不能做祈使句的謂語;
    c. Do you rest是疑問句,不能表示請(qǐng)求;
    d. Resting 是動(dòng)名詞也不能做祈使句的謂語;
    只有b. Rest 可以做祈使句的謂語,所以選b.
    5. a
    本句是將前一句中的間接疑問句...how my brother was 變成直接疑問句,因此時(shí)態(tài)和語序都要作相應(yīng)改變。
    b. your brother was, c. your brother is 都不是疑問句語序,所以都不對(duì)。
    d. was your brother 語序正確,但時(shí)態(tài)不對(duì):間接引語是過去時(shí),直接引語應(yīng)該是現(xiàn)在時(shí)才正確。只有a. is your brother 語序和時(shí)態(tài)都正確,所以應(yīng)該選a.
    6. c
    這是一個(gè)疑問句,a. It likes you , b. Does it like you 和d. Like you 這3個(gè)選擇都意思不通,不符合題目意思,只有c. Do you like 意思通順,符合疑問句語序,因此只能選c.
    7. b
    介詞by 后面加動(dòng)名詞可以表示方式。 本句只能選b. nodding(點(diǎn)頭),因?yàn)樗莿?dòng)名詞,可以放在by 后面作方式狀語。 其他3個(gè)選擇都不能放在介詞by 后面,所以選b.
    8. b
    本句需要選一個(gè)同前一句中時(shí)間短語for a while (一會(huì)兒)意義相同的短語。a. quietly (安靜地),c. while he spoke to me (當(dāng)他跟我說話時(shí)),d. for a long time (很久)這3個(gè)選擇都與for a while 的意義不符。 只有b. for a short time (短時(shí)間)同for a while 的含義相同,因此選b.
    9. d
    a. assembly (集會(huì),聚會(huì)),b. gathering (聚集,收集抽象的東西,如消息等),c. congregation (聚集,聚合) , d. collection (收集,收藏如郵票,硬幣等),只有d適合這個(gè)句子,其他3個(gè)選擇都不能與火柴盒連用,所以選d.
    10. a
    前一句 I nodded(我點(diǎn)頭)表示同意,只有a. agreed (同意)才是這一動(dòng)作所表達(dá)的含義。b. said no (說不),c. shouted (高喊),d. whispered (耳語) 這3個(gè)選擇都不是nodded所表達(dá)的含義,所以選a.
    11. b
    本句需要選出同前一句中的Meanwhile(同時(shí))意義相同的詞或短語。
    a. However(不過,然而);b. In the mean time(同時(shí));c. Never the less(盡管如此,不過);d. Although(雖然);這4個(gè)選擇中只有b.同Meanwhile 的意義相同,所以選b.
    12. c
    a. took it off (脫下),b. took it in (理解),c. took it out (取出),和d. took it up (從事于)4個(gè)選擇中只有c. took it out 同前一句He removed the cotton wool from my mouth(他將藥棉從我嘴里取出)的含義相同,所以選c.
