答案解析
1.C【解析】第一空填形式主语，真正的主语是其后的不定式 to play with fire。第二空填 what，what is difficult 是主语从句，注意 what is difficult 后的谓语动词 is。故选C。
2.C【解析】因为在通常情况下，like 是及物动词，其后应有宾语(句中 it 即为其宾语)。句中的 when 从句不是宾语从句，而是时间状语从句，其中的 when 的意思是“当……的时候”。其实，也有的词典将 I don’t like it when (if) … 作为一个句型来处理。能这样用的动词不多，主要的有enjoy, like, dislike, love, hate, prefer, appreciate等表示喜好的动词。故选C。
3.D【解析】it 用以指身份不明的人。若指身份明确的人，则不宜用it。故选D。
4.A【解析】it 和 one 的区别可简单地概括为：it = the + 名词，one = a + 名词。如：I haven’t got any pens, and I want to borrow one. 我没有钢笔，我想借一支。(one = a pen) 故选A。
5.A【解析】it 为形式宾语，真正的宾语是空格后that引导的宾语从句。see to 意为“负责”、“注意”，其中的 to 为介词，不宜直接跟that引导的宾语从句，遇此情况可借助代词 it。故选A。
6.C【解析】one 指 a coat。比较：it = the +名词，one = a+名词，换句话说，it 是特指的，而one 则是泛指的。故选C。
7.B【解析】it 为形式宾语，真正的宾语是 that he didn’t want to enter politics。故选B。
8.D【解析】it 为形式主语，此句为 People used to think that the Earth was flat 的被动语态形式。故选D。
9.B【解析】it 指前面提到的 new house。注意不能选D，因为其前有并列连词but。故选B。
10.A
【解析】it 为形式主语，其后的that从句为主语从句。故选A。
