英語一般過去時講解和相關解析***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：答案選 C。第一空用過去進行時，表示過去正在發生的情況; 第二空用一般過去時，表示過去突然發生的一件事。
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：答案選 A。注意句中的三個動作：去加拿大→在那兒住了幾年→然後去了美國。由於前後兩個動作用的都是一般過去時，顯然中間的“在那兒住了幾年”應用一般過去時。
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：答案選 B。由於句中增加了插入成分birthdays, awards, graduations，使得句子的主語與謂語were marked分離，從而增加了考生對句子理解的難度。根據句意，空格處應填被動語態; 再根據句中的passed的時態特點可知，空格處也應用一般過去時，故選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：答案選 D。對於剛剛發生的情況，要用一般過去時或過去進行時。答語的意思是：對不起。但我不是有意要弄傷你，我是在把一隻老鼠趕出去。
