英语一般过去时讲解和相关解析(2)
17. 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
解析：答案选 C。第一空用过去进行时，表示过去正在发生的情况; 第二空用一般过去时，表示过去突然发生的一件事。
18. My cousin went to Canada two yours ago. He ______ there for a few months and then went to America.
A. worked B. would work C. would be working D. has been working
解析：答案选 A。注意句中的三个动作：去加拿大→在那儿住了几年→然后去了美国。由于前后两个动作用的都是一般过去时，显然中间的“在那儿住了几年”应用一般过去时。
19. As the years passed, many occasions—birthdays, awards, graduations — ______ with Dad’s flowers.
A. are marked B. were marked C. have marked D. had marked
解析：答案选 B。由于句中增加了插入成分birthdays, awards, graduations，使得句子的主语与谓语were marked分离，从而增加了考生对句子理解的难度。根据句意，空格处应填被动语态; 再根据句中的passed的时态特点可知，空格处也应用一般过去时，故选B。
20. —Ouch! You hurt me!
—I am sorry. But I ______ any harm. I ______ to drive a rat out.
A. didn’t mean; tried B. don’t mean; am trying
C. haven’t meant; tried D. didn’t mean; was trying
解析：答案选 D。对于刚刚发生的情况，要用一般过去时或过去进行时。答语的意思是：对不起。但我不是有意要弄伤你，我是在把一只老鼠赶出去。
