答案与解析
1. It。It可以用来指时间，距离，天气。该句的两部分之间没有连词，所以第一部分只能用非谓语动词，构成独立主格结构。
2. to be。It 作形式主语，形容词（如good, important等）或名词（如a pity; a shame; an honor等）作表语，真正的主语往往为不定式短语to do。
3. applying。It is worth后面接doing sth. It 为形式主语。（注意：It is worthwhile visiting [to visit] the place.
4. doing。It 为形式主语，真正的主语是doing。（注意：It is no use/no good/no pleasure后面通常接doing做真正的主语。）
5. it。该题考查的是一种常见句型，find/feel/think/consider/make it adj/n (如important, right等或名词如a pity; a shame; an honor等) to do sth。
6. talking。find/feel/think/consider it no use/no good/no pleasure doing sth.
7. it。特定句型。其含义是：能即刻回复， 将不胜感谢. 常用于这个句型中的动词还有like, love, hate, prefer等。如：I hate it when people speak with a full mouth.我讨厌人们满口食物的讲话。
8. It。该句考查的是强调句型。
9. it。Make it 是固定搭配，意思是“到达，成功，约定时间”如：Stick to it and you"ll make it. 坚持下去， 就会成功。I wonder if we could make it some other time. 我想知道我们可否把它安排在其他时间。
10. it。it 代指前面的this house。注意：如果是I like ahouse with a small garden very much, but I can’t afford_____.的话，答案最好是one，意思是“一类中的某一个”。
