Question

Everybody can learn ______ well. You have no _____ to be worried about that.

A.how do it; reason B.how to do it; reason

C.what to do; excuse D.what to do it; excuse

Answer

B

【解析】

句意：每个人都能学会如何做好它。你没有理由担心那个。

考查动词不定式和名词。how to do sth如何做某事；what to do sth做什么。这两种结构符合疑问词+to do sth结构，在句中可以做learn的宾语，相当于省略了主语的宾语从句，不能缺少to，排除A。what to do中，what为关系代词，做do的宾语，所以不需要it作宾语，排除D。reason名词，理由；excuse名词，借口。 根据“You have no _____ to be worried about that.”可知，此处表示“理由”，reason符合题意，故选B。
