Ⅰ.单句语法填空(代词)
1.Health experts believe that even a little exercise is far better than ________ at all.
答案：none 解析：考查代词。句意：健康专家认为即使是一点点的锻炼也比没有锻炼好得多。根据句意可知，此处应用none，表示“没有”。
2.Come on! Anybody here can learn to do a rock climb. There is ________ to it really.
答案：nothing 解析：考查不定代词。句意：加油!这儿的任何人都能学会攀岩。真的很简单。There is nothing to it“(做某事)没有困难”，为习惯用语。
3.No matter how busy he is, Tom makes ________ a rule to see his parents every week.
答案：it 解析：考查代词。句意：不论自己多忙，汤姆每周都要去看望父母，这是他的一贯做法。此处用it作形式宾语，后面的不定式短语作真正的宾语。
4.Air quality today is much worse than ________ in the 1980s because of too much air pollution.
答案：that 解析：考查替代词。句意：由于空气污染严重，现在的空气质量比20世纪80年代的空气质量差多了。本空用that代替前面的不可数名词air quality表示同一类别中的不同事物。
5.As the two dictionaries are useful, I'll take ________ and ________ of them is very important to me.
答案：both; either 解析：考查不定代词。句意：由于这两本词典都有用，我会把它们都带走，每一本对我来说都非常重要。根据句意可知，说话人对这两本词典都很满意，故第一空用both;第二空所在句的谓语动词为单数，故空处应用either，表示“(两者中的)任何一个”。
6.If you don't build your dream, someone will hire you to build ________.
答案：theirs 解析：考查代词。句意：如果你不构建自己的梦想，那么就会有人雇用你去构建他们的梦想。所填空在句中作build的宾语，与前面的build your dream呼应，表示build their dreams，因此应用名词性物主代词theirs代替their dreams。
7.—Who is standing over there?
—It must be ________ from an express company.
答案：somebody 解析：考查不定代词。句意：——谁站在那儿?——肯定是快递公司的某个人。表示不确定的某人要用不定代词somebody。
8.—How much bread is there?
—________. I wish you could offer me some.
答案：None 解析：考查不定代词。根据“I wish you could offer me some.”可知，此处表示没有面包了，所以选None。
