过去完成时
过去完成时是很重要的动词的时态，也是学生在使用中常常出错的语法项目，教师应引导学生在了解其基本概念和用法的基础之上，深刻理解“过去的过去”的含义，并在活动中加以体会，最终掌握并灵活运用。
一、过去完成时的基本用法：
（1）表示在过去的某一时间或某一动作之前完成的动作或存在的状态，即“过去的过去”。例如：
a. Before we got to the train station, the train had already left.
我们到达火车站之前，火车就已经离开了。
b. Before I could say "thank you", he had run away.
我还没来得及说谢谢，他就跑开了。
（2）表示从过去某一时间开始，一直延续到过去的另一个时间的动作，常用的时间状语有by then, by the end of, by the time。例如：
a. By the end of last term, we had learnt 2,000English words.
到上学期期末为止，我们已经学习了2,000个英语单词了。
b. They had lived there for ten years by then.
到那时为止，他们已经在那里住了10年了。
（3）表示愿望、打算等的动词，如hope, want, expect, think, mean, suppose, intend, plan等后接从句时,一般用过去完成时表示本打算实现而未实现的愿望和计划。例如：
a. I had intended to meet him at the airport, but I had an important meeting to attend.
我本打算去机场接他，但是我有个重要的会议要参加。
b. I had hoped to take a holiday this year but I was not able to get away.
我原打算今年去度假，可是我离不开。
（4）在句型hardly…when和no sooner…than中，主句用过去完成时，从句用一般过去时，表示“一……就……”。例如：
a. Hardly had I left when it began to rain.
我刚离开就开始下雨了。
b. No sooner had he sat down than the telephone rang.
他刚坐下，电话铃就响了。
练习：
1.I _________(think) you would come the next day, but you didn't.
2.He _________(learn) English for five years before he moved to Australia.
3.It was the second time that he _________(come) to Wuhan.
4.By the end of last term we _________(finish) reviewing six books.
5.They stole my wallet, because I _____(forget) to lock the locker.
答案：

The Miracle of Love
A college professor had his sociology class go into slums（贫民窟）to get case histories (个案史) of 200 young boys. They were asked to write an ①_____ (evaluate) of each boy's future.
In every case the students wrote, “He hasn't got ②_____ chance.” Twenty-five years later another sociology professor came across the ③_____ (early) study. He had his students follow up on the project to see ④_____ had happen to these boys. With the exception of 20 boys who ⑤_____ (move) away or died, the students learned that 176 of the ⑥_____ (remain) 180 had achieved more than ordinary success as lawyers, doctors and businessmen. The professor was ⑦_____ (shock) and decided to pursue the matter further.
⑧_____ (fortunate), all the men were in the area and he was able to ask each one, “How do you account ⑨_____ your success？”In each case the reply came with feeling, “There was a teacher.” The teacher was still alive, so he sought her out and asked the old but still alert (思维敏捷的) lady what magic formula（方法）she had used ⑩_____ (pull) these boys out of the slums into successful achievement. The teacher's eyes sparkled and her lips broke into a gentle smile.
“It's really very simple,” she said. “I loved those boys.”
答案：①evaluation ②a ③earlier ④what ⑤had moved ⑥remaining ⑦shocked ⑧Fortunately⑨for⑩to pull
解析：①考查名词。由句意可知，他们被要求对每个男孩的未来写一份评价，故此处应该使用其名词形，式evaluation。
②考查不定冠词。根据语境可知，此处应用不定冠词，意思是“他没有机会”。
③考查形容词的比较级，这里应该用形容词的比较级形式，表示“更早的那个研究”。
④考查名词性从句。根据语境可知，他让他的学生继续研究这个项目，看看这些男孩到底出了什么事。故what引导宾语。
⑤考查动词时态。根据语境可知“move”所表示的动作发生在过去的过去，因此这里应使用过去，完成时。
⑥考查现在分词作定语。由语境可知，这里用现在分词形式作定语，修饰后边的180。
⑦考查非谓语动词的过去分词形式作表语。设空处与空前的was构成系表结构，且主语是The professor，因此此处应填shocked。
⑧考查副词。根据语境可知，此处表示“幸运的是”，故应使用副词形式Fortunately。
⑨考查介词。account for为固定搭配，意思是“解释”，本句意思：你如何解释你的成功？
⑩考查非谓语动词不定式作目的状语。句意：她用了什么神奇的方法把这些男孩从贫民窟拉出来，取得了成功。故填to pull。
