答案與解析
1. It。It可以用來指時間，距離，天氣。該句的兩部分之間沒有連詞，所以第一部分只能用非謂語動詞，構成獨立主格結構。
2. to be。It 作形式主語，形容詞（如good, important等）或名詞（如a pity; a shame; an honor等）作表語，真正的主語往往為不定式短語to do。
3. applying。It is worth後面接doing sth. It 為形式主語。（注意：It is worthwhile visiting [to visit] the place.
4. doing。It 為形式主語，真正的主語是doing。（注意：It is no use/no good/no pleasure後面通常接doing做真正的主語。）
5. it。該題考查的是一種常見句型，find/feel/think/consider/make it adj/n (如important, right等或名詞如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。其含義是：能即刻回復， 將不勝感謝. 常用於這個句型中的動詞還有like, love, hate, prefer等。如：I hate it when people speak with a full mouth.我討厭人們滿口食物的講話。
8. It。該句考查的是強調句型。
9. it。Make it 是固定搭配，意思是「到達，成功，約定時間」如：Stick to it and you'll make it. 堅持下去， 就會成功。I wonder if we could make it some other time. 我想知道我們可否把它安排在其他時間。
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_____.的話，答案最好是one，意思是「一類中的某一個」。
