The
principal's inbox has been flooded with emails from students wondering whether to be hopeful
about a new teacher.
whether 引导名词性疑问分句时,可以使用省略形式:whether to do...。whether to be hopeful about
a new teacher. 等于:whether they should be hopeful about
a new teacher.
其实,引导名词性从句的其他疑问代词或副词,也可以使用省略形式:wh-word + 不定式。
如:what to do, where to go, how to find it, whom to meet
等。
