Question

【题目】My biggest challenge is _______how to behave at the dinner table.

A.learnB.to learnC.learns

Answer 1

【答案】B

【解析】

句意：我最大的挑战是学会如何在餐桌上举止得体。

考查非谓语动词。learn 动词原形；to learn动词不定式；learns动词三单；此处是不定式作表语，表示目的、内容和将来，结合“My biggest challenge is _______how to behave at the dinner table.”此处是动词不定式，表目的。故选B。
