题目内容
4.-Can't you make any good friends if youaren't(not be) polite enough?-I must make the change.
分析 如果你不够礼貌,难道就不能交到好朋友吗?
--我必须做出改变.
解答 答案:aren't.
根据Can't you make any good friends if you--(not be) polite enough,可知如果你不够礼貌,难道就不能交到好朋友吗?这里if引导的条件状语从句,主句是can't引导的句子,从句应该用一般现在时.故填aren't.
点评 单词填空类型题要充分理解句意,再根据单词提示完成试题,注意时态,单复数,词性等变化.
