Question

【题目】He has a habit of keeping his arms___when talking to others,which___impolite to his audience

A.to be folded;is

B.being folded;are

C.folded;is

D.folded;are

Answer 1

【答案】C

【解析】句意：他有一个和别人谈话时交叉双臂的习惯，这对他的听众是不礼貌的。fold one’s arms交叉双臂，fold和his arms之间构成逻辑上的动宾关系，所以要用fold的过去分词作宾语补语，在which引导的非限制定语从句中，which指代前面的内容，故用is，不用are。
