题目内容
10.I along the street looking for a place to park the accident happened.( )| A. | went;when | B. | went;while | C. | was going;when | D. | was going;while |
分析 当事故发生的时候我正在街上找地方停车.
解答 答案:C.结合the accident happened这里用when引导的时间状语从句,主句用过去进行时,从句应用一般过去时,主句主语I,故was,故答案是C.
点评 when,while都有"当…时候"的意思.when既可表示某一点时间,也可以表示某一段时间.在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,可与主句中的谓语动词同时发生,也可在其后发生.例如:1、I was just reading a book when she came into my room.她走进我房间时,我正在看书.2、Were you writing when the teacher came in?老师进来的时候,你在写信吗?3、When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想.
