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。
