I ________ along the street looking for a place to park when the accident ________.
A.went; was occurring
B.went; occurred
C.was going; occurred
D.was going; had occurred
试题答案
C
解析:句意:我沿着街道找停车位,这时发生了事故。occur是瞬间动词,此处不用进行体,可排除A项;且沿街行车与车祸几乎是同时发生,可排除D项;车祸发生时,车是在行进中,因此C项最佳。此处是when(这时,突然)句式之一。如:①I was watching TV when someone knocked at the door.②I was about to go out when someone knocked at the door.③I had just finished my homework when someone knocked at the door.
