题目内容
13.-I didn't invite him to the party but he came anyway and got completely drunk.-_________ he hadn't come!The party could have been a success.( )
A. | How come | B. | Only if | C. | What if | D. | If only |
分析 -我没有邀请他参加聚会但他还是来了并且喝得大醉.
-要是他没来就好了!聚会一定很成功.
解答 答案:D
题干he hadn't come用的是过去完成时态,句中没有参照时间,用在从句中对过去事实的相反假设,是虚拟语气;The party could have been a success情态动词加完成时态,表示对过去事实的相反假设;how come怎么了,only if只有在某种条件下,what假若,if only要是怎样该多好;句意表达的是虚拟条件,故选D.
点评 从属连词是连词的一种,用来引导名词性从句和状语从句.大致可分为三大类:that (无词义,不做成分)if,whether (表达是否的意义,但不做句子成分); 连接代词:who,whom,whose,what,which,whatever,whoever,whichever(有词义,在句子中可作主语、表语、宾语);连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语).
