题目内容
【题目】—Ma Long won the men's singles final match at the 2017 Word Table Teanis Championship. exciting news it is!
A.What
B.What a
C.What an
D.How
【答案】A
【解析】句意:—马龙赢得了2017年世界乒乓球锦标赛男子乒乓球单打冠军。—多么令人激动的消息呀!本题主要考查感叹句。由于 news 是不可数名词,所以可排除B和C。若用 how 来引导,这句话应该是 How exciting the news is,因为 how 引导的感叹句的结构是“how + adj./adv.+主语+谓语”。用what引导的感叹句来修饰不可数名词的结构是“what+adj. +不可数名词+主语+谓语”,符合题意。故选A。
