❺ 求21世纪大学英语应用型综合教程3答案,要完整的.

Ⅰ. ADCDBBCBCAAACDB Ⅱ. 1. A 题意：“棒球在哪里？”“它在床底下。”根据答语under the bed可知是提问地点,所以应是where; how是表示 “怎么样”； What是“什么”，提问事物; Where is= Where‟s，由于句中已有is，故选A。 2. A 题意：请带我到学校。take是“带走”，bring是“带来”，call是“打电话”，need是“需要”，另外“take…to+地点”是“带„„到某地”，故选A。 3. C 题意：“我的书在梳妆台上吗？”“是的，它在。我能看见。”根据答语可推知是肯定回答，由于在简短的肯定答语中it is不能缩写，故选C。 4. D 题意：“铅笔在哪里？”“它们在桌子上。”由于pencils是复数，所以应用they，them是宾格，不能做主语。故选D。 5. B 题意：“那些是什么？”“是我们的足球。”soccer balls是复数，故排除A项，C项和D项分别提问人物和地点，所以答案为B。 6. C 题意：“我的钢笔在哪里？”“很抱歉，我不知道。”pens为复数形式，所以谓语动词应是are；I know的否定形式需加助动词，所以应是I don‟t know。故选C。 7. A 题意：这是一支钢笔。这支钢笔很漂亮。a用于辅音音素之前，an用于元音音素之前，

两者均用于泛指。the指上文提到过的人或事物，所以答案为A。 8. B 题意：“书包在桌子上吗？”“不，它不在桌子上。”本句是is引导的一般疑问句，A、D项都涉及地点，故排除，C项为复数形式，与问句不符，所以答案为B。 9. C 题意：“他的铅笔在哪里？”“我不知道。”where引导特殊疑问句, A项和D项是一般疑问句的答语，故排除;句中pencils是复数，所以B项单数形式不对。只有C项符合题意。 10. A 题意：光盘在哪里？由于CDs是复数，所以答案应为A。 11. D 题意：“棒球在哪里？”“在地板上面的桌子底下。”under意为“在„„的下面”，on意为 “在„„上面”，根据题意应选D。 12. B 题意：我妈妈在房间里。in意为“在„„里面”，on意为“在„„上面”，is是本句的谓语动词，不能省略，所以答案为B。 13. C 题意：请把这些东西带给你妈妈。短语take…to…意为“把„„带给„„”。too意为“也”， at是“在（点刻）”，to是“朝、向、至、达”，in是“在……里面”，根据题意和固定短语应选C。 14. B 题意：“你的夹克衫在沙发上吗？”“是的，它在沙发上。”is引导一般疑问句，由于your jacket是单数，并且是物，所以正确答案为B。 15. A 题意：“我的钥匙在哪里？”“它们在床上。”根据答语on the bed可知是提问地点，由于they是复数，故选A。Ⅲ. 1. my 2. and 3. is 4. under 5. some Ⅳ. 1. Where is 2.Where are 3. are not 4. Is; your；No; isn‟t 5. are; bags Ⅴ. 1. take; to 2.on; dresser 3. Where; under 4. bring; to 5. on; floor Ⅵ. 1. D 根据题意是吉姆的房间，所以用名词所有格，即在名词后加“‟s”。 2. B 由于old以元音音素开头，又表示“一”，所以用an。 3. A there be 结构意思是“有”，并使用就近原则，所以谓语动词与a clock保持一致。 4. B 表示在墙的表面用介词on，表示镶嵌在墙的里面用介词in。根据题意应选B。 5. B 由于谓语动词是is, 所以主语应是单数形式。 6.A 本题意为：背包在椅子上。on意为“在„„上面”，in 意思为“在„„里面”，between“在两者之间”，out“在外面”，根据句意应选on。 7. B 表示特指，所以用定冠词the。 8. A 本句意为：棒球在门的后面。其它三项都不与door搭配，故选A。 9. D it指代上文的that，谓语动词用is，缩写为It‟s。 10. C 本句意为：它看起来像一顶帽子。look like意为“看起来像”，look意为“看起来”，look after意为“照看，照顾”，又由于主语是it，所以谓语动词用第三人称单数。Ⅶ. A) 1. C 根据文中第一句话There is a library(图书馆) in our school.可知答案为C。 2. C 根据文中第四句话Our school library is not very big,可知答案为C。 3. D 根据文中第五句话There are many books in the library.可知答案为D。 4. B 根据文中第七句话Some are in English.可知答案为B。 5.
