疑问句改装的名词从句

典型的名词从句是外加连接词 that ,表示“那件事情”( that thing)。另外,以疑问词( who、what、when 等)引导的疑问句,也可以改装成名词从句,代表一个问题( the question )。例如:

  1. I know the question.

    S V O

  2. Who are you?

    → (A) I know who you are.(我知道你是谁。) S V O

例2中 Who are you? 只要改写为非疑问句的顺序 who you are 即成为名词从句,以疑问词 who 当连接词用,不必再加连接词,直接把这个从句放人例1中 the question 的位置,作为 know 的宾语,即成为(A)的复句。再看一个例子:

1.The question is anybody's guess. S 2.When will the bomb go off?

→ (A) When the bomb will go off is anybody's guess. S (炸弹什么时候会爆炸没有人知道。)

例2的疑问句只要改成非疑问句的顺序 when the bomb will go off 就成了代表一个问题的名词从句,不必加连接词,可以直接放入例1的主语位置构成(A)的复句。
