选哪个说下原因?

Answer 1

C 此处policy是不可数名词,表示“（针对某一问题或某国的）政策,态度,行动”,所以不用a;是泛指,保持身体健康是好的态度,无论是冬天或夏天.所以也不用定冠词the



  2.C--用unless引导的条件状语从句,要遵循“主将从现”的时态---主句将来时,从句就用一般现在时.


   3.C--pass time"消磨时光"


   4.D---assure"向.保证"；A和B都是说服某人的意思,不合题意；C虽然也有向.保证之意,但guarantee是保证做到某事,还有正面意义,而句子中可看出已经冒犯了,所以不适当.


   5.C--fame和popularity都是不可数名词,前面不能加a;impression一般指粗略的印象和感觉,侧重于对别人留下的某种印象,而这里for fair dealing 是supermarket发出的,所以用impresssion也不适当.name在这里做可数名词“名声”讲.
