一、that与whether/if引导的名词性从句
1．that引导的名词性从句
that在名词性从句中不作任何成分，本身无意义，可引导所有的名词性从句。that 引导主语从句、表语从句和同位语从句时通常不能省略，引导宾语从句时有时可以省略。
That Tu Youyou had been awarded the 2015 Nobel Prize in Physiology or Medicine made us very proud.

【温馨提示】 that引导宾语从句时通常不能省略的情况
(1)从句作learn、request、insist、suggest、explain、agree、wonder、prove、feel等动词的宾语时，that往往不省略；
(2)宾语从句前有插入语时；
(3)动词后跟有多个 that 引导的宾语从句时，只有第一个 that可以省略，从第二个从句开始that 不可省略。

2．whether/if引导的名词性从句
(1) whether和 if本身有意义，意为“是否”，在从句中不充当句子成分。
(2)whether可引导所有名词性从句，if主要引导宾语从句或不在句首的主语从句。
(3)whether与 if引导宾语从句时大多数情况下可以互换，但下列情况下宜用whether：
①后面直接跟or not 时； ②位于介词后引导宾语从句时。
