A. knew B. have known C. had known D. know
分析：C。根據(jù)主句中的felt可知，其后的賓語(yǔ)從句應(yīng)用過(guò)去時(shí)態(tài)，故可排除B和D；再根據(jù)語(yǔ)境和句中的for years可知用過(guò)去完成時(shí)比用一般過(guò)去時(shí)更佳。
22. The moment I got home, I found I ______ my jacket on the playground.
A. had left B. left C. have left D. was leaving
分析：A。因?yàn)椤鞍褗A克上衣落在操場(chǎng)上”這一動(dòng)作發(fā)生在“發(fā)現(xiàn)”這一過(guò)去動(dòng)作之前，所以要用過(guò)去完成時(shí)。
23. Mary went to the box office at lunchtime, but all the tickets ______ out.
A. would sell B. had sold C. have sold D. was selling
分析：B。句意為：瑪麗午餐時(shí)間去售票處，但所有的票都已售罄。很顯然，票在瑪麗到達(dá)前已售完，屬于過(guò)去的過(guò)去，故用過(guò)去完成時(shí)。又如：I finally had to sell the car, but it had served its turn. 我最后只好把汽車(chē)賣(mài)了，不過(guò)也算是物盡其用了。
24. John was given the same suitcase his father and grandfather ______ with them to school.
A. took B. had taken C. were taking D. would take
分析：B。根據(jù)句意，約翰的爸爸和爺爺用這個(gè)皮箱是發(fā)生在約翰得到這個(gè)皮箱之前，所以空格處應(yīng)填過(guò)去完成時(shí)。句意為：約翰的爸爸和爺爺以前上學(xué)用的皮箱現(xiàn)在被拿給約翰用了。
25. She stared at the painting, wondering where she ______ it.
A. saw B. has seen C. sees D. had seen
分析：D。因動(dòng)詞see所表示的動(dòng)先于stare和wonder之前，所以它要用過(guò)去完成時(shí)。答案D。句意為：她盯著那幅畫(huà)，琢磨著在哪看過(guò)這幅畫(huà)。
26. —Were you surprised by the ending of the film?
—No, I ______ the book, so I already knew the story.
A. was reading B. had read C. am reading D. have read
分析：B。由于問(wèn)句中用的時(shí)態(tài)是一般過(guò)去時(shí)(were)，說(shuō)明對(duì)話(huà)雙方是在談?wù)撘徊窟^(guò)去看過(guò)的電影；而根據(jù)so I already knew the story（所以我已經(jīng)知道故事情節(jié)了）可知，說(shuō)話(huà)者“看這本書(shū)”應(yīng)該是在“看電影”之前，故用過(guò)去完成時(shí)。
27. It took me a long time before I was able to fully appreciate what they ______ for me.
A. had done B. did C. would do D. were doing
分析：A。比較主句中的動(dòng)詞take與從句中的動(dòng)詞do，很顯然do在先，take在后，而take在句中用的是一般過(guò)去時(shí)，故do要用過(guò)去完成時(shí)。
28. I was just going to cut my rose bushes but someone ______ it. Was it you?
A. has done B. had done C. would do D. will do
分析：B。根據(jù)句意可知，“有人給玫瑰剪枝”發(fā)生在“我去給玫瑰剪枝”之前，而“我去給玫瑰剪枝”用的是I was just going to cut my rose…這樣的過(guò)去時(shí)態(tài)，故“有人給玫瑰剪枝”發(fā)生在這一過(guò)去時(shí)間之前，也就是“過(guò)去的過(guò)去”，故用過(guò)去完成時(shí)。
29. —Peter, where did you guys go for the summer vacation?
—We ______ busy with our work for months, so we went to the beach to relax ourselves.
A. were B. have been C. had been D. will be
分析：C。根據(jù)句意可知，“很忙”在“去海邊放松”之前，而“去海邊放松”用的是一般過(guò)去時(shí)went，所以“很忙”應(yīng)用過(guò)去完成時(shí)had been。
