新概念英语第二册课后习题答案详解_and_单元测试答案(全)

新概念英语第二册课后习题答案详解Lesson 11. b 选 b 最为正确。

因为 a.d.都与课文内容不符合，也不合乎逻辑； c.的意思是“他们没有注意他”，而作者的意图并不是想让他们注意他，而是想让他们停止谈话。

所以选 b. 最能表达作者当时心里的感受。

2． c 其余 3 个答案都与原句意思不符合。

3． b 因为 a. to 不对，可以是 He went to the theatre;c. into 也不对，可以是He went into the theatre;d. on 更不符合语法，表示在某一个地方用介词 in 或 at, in 表示在大的空间，如国家，城市等，at 则表示在小的地点或空间，如atthe office, at the theatre 等 , 所以选 b.是正确的。

4．db. above(在,, 上方)；c. ahead of (在,,的前面，在 ,, 之前) 不和 behind对应，也不强调位置的前后顺序。

a. before和 d. infront of都是和behind 对应的，都有“在 ,, 前面”的意思。

但in front of 更具体的强调位置，而before 则包含更宽泛的意思，即时间上，空间，次序，登记，重要性方面的“在 ,, 前面”5． c 因为用 a. Where, b. why, d. when提问都不符合逻辑，都不是针对状态提问的，只有How 提问，才能用 Angry 回答。

6． ab. they 只做主语； c. their 只能做定语；d. us 虽然可以做宾语，但与前一句意思不符合。

7．da. none 是代词，很少用在名词前面； b. any 只能用在否定句或疑问句中； c. not any 不符合语法，因为前面没有助动词did.8.ba. chair( 椅子 ) ， c. armchair( 手扶椅 ) d. class(班级 ) 这 3 个选择都和seat 的意思不符合。

After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say. 'It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all! New words and expressions 生词和短语catch v. 抓到(caught, caught)fisherman n. 钓鱼人，渔民boot n. 靴子waste n. 浪费realize v. 意识到参考译文钓鱼是我特别喜爱的一项运动。

我经常一钓数小时却一无所获，但我从不为此烦恼。

有些垂钓者就是不走运，他们往往鱼钓不到，却钓上来些旧靴子和垃圾。

新概念英语第二册第二十课课后习题答案详解
Lesson 20
1. b根据课文第4行I never catch anything---not even old boots, 只有b. nevercatches anything 与课文实际内容相同，而其他3个选择都与课文内容不符。

根据课文最后一句I am only interested in sitting in a boat and doing nothingat all! 只有c. doing nothing 是正确答案，而其他3个选择都不符合课文内容。

本句是对主语提问的，回答是. who (谁)是对主语提问的；c. whom(谁)是对宾语提问的；d. whose(谁的)确是对定语提问的；只有b. which 是对做主语的事物提问的，所以选b.
本句是带never的否定句，只有b. anything 可以用在否定句中。

而a. nothing若用在否定句中，就会使原句变成肯定意义的句子，不符合题目意思；c. something 只能用于肯定句中；d. everything也不能用在否定句中。

前面句子I am even less lucky 中的less(不及)是表示否定意义的比较级,只有c. not so是表示否定意义的,而其他3个选择都没有否定的意思.
只有b. an empty bag 最符合语法。

而其他3个选择都有语法错误。

a. a empty bag 中empty是以元音开头的，前面不能用a 而应该用an;
c. empty bag 中bag 是可数名词，需要用an 来修饰；
d. oneempty bag 不符合习惯用法，单数可数名词前通常用不定冠词a 或an 修
饰，除非表示强调才用one 修饰。

因此应该选b.
只有 c. all 才能使这个句子同前一句I am only interested in doingnothing.的含义相符合，all等于the things that ，可以代替doing nothing. 而其他3个选择中a. only 和d. the only 不符合语法，b. the one 不符合题目意思，不能完全表达清楚。

只有a. the one I like best 才能解释前一句的my favourite sport(我最喜爱的一项运动)，而b. cd.都不符合题目的意思。

只有c.triestocatch(设法捕获)才是afisherman(钓鱼人)通常做的，而其他3个选择a.buys(买)，b.sells(卖)，
d.keeps(保存)都不符合题目意思，所以应该选c.
只有c.catches(fish)有“钓鱼”的意思，而其他3个选择a.holds(握，拿)，b.takesholdof(抓住，捉住)，d.takes(拿，带)都不能同fish构成固定短语，表示钓鱼。

只有d.gohome是固定短语，意思是“家”。

a.tohome不符合习惯用法，不能说gotohome;b.tohouse和c.tothehouse也不符合习惯用法。

只有a.stop同前面的giveup(放弃，停止)意思相近，而其他3个选择b.begin(开始)，c.surrender(投降)与d.end(结束)都不符合题目意。
