新概念英语第二册第二十课课后习题答案详解 Lesson 20教学内容
新概念英语第二册第二十课课后习题答案详解Lesson 201. 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。
2.c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。
3.b 本句是对主语提问的，回答是Fishing.a. 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.4.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。
5.c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.6.b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.7.c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。

一、词汇catch v. 抓到fisherman n. 钓鱼人，渔民boot n. 靴子waste n. 浪费realize v. 意识到★catch v. 抓到①vt. 捉住，逮住，捕获The police have caught the thief.②vt. 抓住，握住Can you catch the ball?③vt. 及时赶到，赶上catch up with 赶上，跟上Go ahead please.I’ll soon catch up with you.★boot n. 靴子a pair of boots 一双靴子★waste n. 浪费①n. 浪费a waste of… 浪费……It is a waste of time/money/food/water.②vt. 浪费You are wasting time.★realize v. 意识到①v. 认识，知道，明白，意识到I went into the wrong room without realizing it. 我无意中走错了房间。
I realized that I was wrong.②v. 实现（希望、目标、愿望等）realize one's dream 实现某人的梦想She has realized her hope to be an actress.③使变为事实，使发生（常用于被动语态）This plan can never be realized.二、课文讲解1、Fishing is my favourite sport.fishing是一个动名词，由动词+ing组成，动名词可以作主语或宾语，如eating，reading等等★fish①n. 鱼（不可数名词），鱼的种类（可数）There are a lot of fishes(表示种类)in the sea.②v. 钓鱼, 捕鱼2、I often fish for hours without catching anything.for+时间表示一段时间for hours=for some hours 数小时without catching anything作为状语而出现, 表示结果状语。
without 是介词，后面一定要加宾语, 动名词catching作 without 的宾语，without 后面的动作是主语来做的。
动名词也有动词的特性，可以有自己的宾语。
without 通常表示“缺乏、没有”；当它位于动名词前时，表示“不曾、不”I can’t repair the car without your help.They tried to leave the restaurant without paying.He went out without saying any words.3、But this does not worry me.★worryv. ①烦恼，担扰worry sb. 某人为……烦恼，担扰adj. 担心be worried about ……为……担心I was worried about my little daughter.4、Instead of catching fish, they catch old boots and rubbish.instead of… 我原准备做……但是后来做了……（instead of 后面的词一定是没有做的）I went to school instead of staying at home. 我没呆在家里而是去上学了I bought books instead of buying dresses.without强调没有做某件事, instead of强调这件事没做成而做成了另外一件事副词instead“作为替代，反而”，单独使用时一般出现在句尾If you don’t want a holiday in England, why don’t you go to Australia instead?5、I am even less lucky.less是little的比较级，意为“不及，不如，更少”I spend less time on English than on French.less+原形A is less…thanB A不如B6、After having spent whole mornings on the river, I always go home with an empty bag.spend+时间+在某地在某地度过……时间after <conj.>+从句在……之后after <prep.>+名词/动词的ing形式……之后（从句主语必须是主句的主语时两种形式可互换）After I go to school, I learned a lot of knowledge. (用一般式表示一个事实, 不用“went to” ) After going to school, I learned a lot of knowledge.介词after的宾语的动名词having spent所表示的动作发生在谓语动词go 之前，所以动名词用完成形式。
with an empty bag 注意连读with sth. 有……的，持有……的，随身带着……(状语)Who’s the man with the beard?without sth. 没带……I always go home without angthing. 什么都没带回家7、'You must give up fishing!' my friends say.give up doing sth. = stop doing sth. 放弃做某事Give up smoking.8、I'm not really interested in fishing.be intersted in sth. / doing sth. 对……感兴趣I’m interested in collecting stamps.三、语法动名词动词+ing 作名词时称为动名词，它仍有动词的属性，可以接宾语，动名词可以代替名词做主语和宾语或介词宾语。
1、动名词作主语Watching television is my favourite pastime. 看电视是我最喜爱的业余爱好.2、动名词作宾语Do you mind turning on the TV?Betty enjoys listening to pop music.3、利用介词/副词+动名词可以把两个句子连成一个句子apologize for (not) doing sth. 为什么事情而道歉I must apologize. I interrupted you. 我得表示道歉. 我打断了你的说话(工作).I must apologize for interrupting you.由于打断了你的说话(工作), 我得表示道歉. （for interrupting强调interrupt这个动词）I must apologize for having interrupted you.（for having interrupted 强调interrupt这个动词先发生，强调时间 (having done)）以上两者为时间概念不同，意思相同congratulate (sb.) on doing sth. 因……祝贺（某人）He congratulated me. I won the competition. 他向我道贺. 我赢得了这次比赛.He congratulated me on winning the competition. 在我赢得这次比赛之际, 他向我祝贺.He congratulated me on having won the competition.thank you for listening/attending动名词用表示完成时的 having+过去分词结构往往强调动名词的动词发生在前面。
4、跟动名词的短语be keen on doing sth.（热忠于……）,be fond of,be interested in,enjoy doing sth.（喜欢做某事）， congratulations on doing sth. （祝贺……）be afraid of可以带动名词的介词有：before，after，without，instead of等I can’t watch TV without falling asleep. 我看电视时必定会睡着。
Exercises C(用括号中的词来连接下列句子, 如需要可对原句进行必要的改动)2.She bought a pair of boots. (instead of) She did not get a pair of shoes.She bought a pair of boots instead of getting a pair of shoes.＝She bought a pair of boots instead of a pair of shoes.4.(After) She heard the news. She fainted.after+从句； after prep.+doingAfter hearing the news,she fainted. （faint vi.昏晕, 昏倒）四、特殊难点Interested and Interesting. Excited and Exciting.大多数现在分词和许多过去分词都可以作形容词用。
以-ed结尾的形容词常与人称主语连用，表示人的情绪、状态、喜好等；以-ing结尾的形容词则常与非人称主语连用，表明事物的某种特征、性质等。
Fishing is not interesting. I am not really interested in fishing.钓鱼没意思. 我对钓鱼并不真正感兴趣.The match was very exciting. The crowd got very excited.比赛非常激动人心. 观众非常激动.。
