They had planted six hundred trees before last Wednesday.It was the third time that he had been out of work that year.I had finished reading the novel by nine o'clock last night.We had learned over two thousand English words by the end of last term.They had planted six hundred trees before last Wednesday.表示“一就”的几个句型Hardly/No sooner/Scarcely had +主语+过去分词+ when/than/before +一般过去时We had no sooner been seated than the bus started. = No sooner had we been seated than the bus started.“时间名词 + before”在句子中作状语,谓语动词用过去完成时；“时间名词+ago”在句中作状语,谓语动词用一般过去式；He said his first teacher had died at least 10 years before.Xiao Hua left school 3 years ago.过去完成时表示“”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时.这种用法常出现在：（1）中当宾语的主句为,且从句的动作先于主句的动作时,从句要用过去完成时.在told, said, knew, heard, thought等动词后的宾语从句.（2）中在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时.（3）表示意向的,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示过去未曾实现的想法,希望,打算或意图.意为"原本,未能"（4）根据上、下文来判定（1）中She said that she had seen the film before.她说她已经看过这部电影了（2）中After he had finished his homework, he went to bed. 做完作业后,他上床睡觉了注意： before, after 引导的时间状语中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,用一般过去时表示过去完成时,则主、从句都用.After he closed the door, he left the classroom.After he (had)left the room, the boss came in.We arrived home before it snowed.（3）表示意向的We had hoped that you would come, but you didn't.我们原本希望你来,但你没有来.（4）根据上、下文来判定I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.我昨天在街上遇见了王滔.自从他去北京,我们都没有见过面四 与现在完成时的区别现在完成时过去完成时表示的动作发生在过去,以now的时间为基点,但侧重对now产生的结果或造成的影响过去完成时则是一个相对的时态,以过去时间为基点,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动作相比较时,才用到它比较：I have learned 1000 English words so far.到目前为止我已经学会了1000个英语单词I had learned 1000 English words till then.到那时为止我已经学会了1000个英语单词 I'm sorry to keep you waiting.对不起,让你久等了 Oh, not at all. I have been here only a few minutes.没什么,我只等了几分钟五 与一般过去时的区别1.时间状语不同：过去完成时在时间上“过去的过去”；而一般过去时只强调过去某一特定的时间.比较：They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday.2. 过去完成时表示过去的过去,不单独使用,一般和一般一起使用When I got to school,I realized I had left my backpack at home.3.当两个或两个以上接连发生的动作用 and 或 but 连接时,按时间顺序,只需用一般过去时来代替过去完成时；另外,在before,after,as soon as引导的中,由于这些本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时.He entered the room, turned on the light and read an evening paper.【大展身手】1When I got to the cinema，the film for the minutes Ahas begun Bhad begun Chad been on Dwas on2He to the lab than he set out to do the experiment Ahas no sooner got Bwas supposed to Cwill no sooner get Dhad no sooner got3He stepped into the office， down and began to fill in the forms Asitting Bto sit Csat Dhaving sat4The little girl her heart out because she her toy bear and believed she wasnt ever going to find itAhad cried；1ost Bcried；had loseChas cried；has lost Dcries；has 1ost5 The pen I I is on my desk，right under my nose Athink；lost Bthought；had lost Cthink；had lost Dthought；have 1ost6.
