Question

【题目】My sister hardly ever eat junk food_____ keep healthy.

A. so thatB. in order toC. forD. in order that

Answer 1

【答案】B

【解析】

句意：我妹妹几乎从不吃垃圾食品以便保持健康。A. so that以便，其后跟句子；B. in order to为了，跟动词原形；C. for为了；D. in order that为了（后面跟句子）。根据keep healthy可知，keep是动词原形，因此排除A/D；for是介词后跟动名词，所以选项C不对。故选B。
