新概念英语第二册第二十课课后习题答案详解 Lesson
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。
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。

语法 Grammar in use
动名词 (The Gerund)(1)
动名词和现在分词的形式完全一样，都是由动词 +-ing 构成。
- ing 形式作名词时称为动名词。
从广义上讲，动名词能够代替名词，
即使它像动词一样可带宾语。
像名词一样，它能够作主语：
Dancing is fun. I love it.
跳舞有意思，我喜欢跳舞。
Walking quickly is difficult.
走快是很难的。
( 动名词 +副词作主语 )
Washing the car makes him dirty.
擦洗汽车把他身上弄脏了。
( 动名词 +宾语作主语 )
动名词也能够作宾语或介词宾语：
Mary is keen on cooking.
玛丽热衷于烹调。
( 介词宾语 )
Congratulations on passing your exams!
祝贺你通过考试 !
能够带动名词的介词通常有before, after, instead of,
without 等。
用介词 +动名词结构能够将两个短句合为一句话，或者将一个从句变为动名词结构。
动名词的否定式是在它前面直接加not ：
Tom always knocks before entering a room.
汤姆在走进一个房间前总要敲门。
He apologized for not writing to you.
他为没给你写信而表示道歉。
动名词也能够用表示完成时的having +过去分词结构：
You can't leave the restaurant without having paid the
bill.
在没有付账之前你不能离开饭店。
