题目内容
1. is reported in the newspaper,the air pollution in some big cities,such as Beijing and Wuhan,has become more and more serious.( )A. | That | B. | Which | C. | As | D. | What |
分析 正如报纸中报道的那样,一些大城市比如北京、武汉等里的空气污染已经变得越来越严重.
解答 答案:C.
本句属于对非限制性定语从句的考查.定语从句中缺少主语,且位于句首,that和what均不能引导非限制性定语从句,which引导非限制性定语从句时不能位于句首,故选C.
点评 在as引导的非限制性定语从句中,连接代词as在句子中可以作主语、宾语或表语等,可以指人或物.其在定语从句中的位置比较灵活,即可以在句子 前面,在句子中间或句子末尾.常用的结构有:as we all know; as is well known to…; as is often the case; as is said/mentioned/reported above; as I told you before; as often happens; as is/was expected; as I can remember等.
