题目内容
15.The air quality in the city,asis shown in the report,has improved over the past two months.分析 在过去的两个月中这座城市的空气质量得到了改善,正如报告中显示的.
解答 答案是as;本题考查as引导的非限制性定语从句;as引导的非限制性定语从句指代的是整个主句的内容,可以放在主句前、主句中或主句之后;which也可以引导非限制性定语从句指代整个主句的内容,但是which从句只能放在主句之后;本题中的关系词指代的是主句"The air quality in the city has improved over the past two months.",并且位于主句中,故答案用as.
点评 本题考查as引导的非限制性定语从句;用理解as引导的非限制性定语从句与which引导的非限制性定语从句指代主句的区别的基础上结合具体语境判断.
