My mother was cooking _______ I got home yesterday.A.whileB.asC.whenD.after
题型:不详难度:来源:
My mother was cooking _______ I got home yesterday. |
答案
C |
解析
when, while和as的区别:when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。并且when有时表示“就在那时”。 While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。 As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。 After表示主句动作发生在从句动作之后。根据题意,当我昨天到家时母亲正在做饭,也许母亲早已开始做饭了,这里强调的是那个时候,所以选C。 |
