参考答案及详解
16.C。it作形式主语。
17.A
18.D。
19.A。该题考查it作形式宾语的用法。四个选项均为代词,只有it作先行代词时,本身没有具体意义,而只是帮助把真正的宾语移到句子后部去,句中it的作用是代替它后面宾语从句when people talk with their mouths full。
20.B。注意:此句不是由that引导的定语从句,而是由It is...that构成的强调句。被强调部分是the ability to do the job(作句子的主语)。matters为谓语。整个句子是将the ability to do the job与where you come from和what you are相比较哪一个更重要。译为:至关重要的是工作能力而不是你是哪里人或是干什么的。类似的例子:It was on Sunday that I saw him,not on Saturday.
