过去完成时态
过去完成时态学习目标1.了解过去完成时定义、构成、用法。
2.掌握过去完成时与现在完成时的区别及用法。
3.进一步学习延续性动词与非延续性动词的区别及转变。
定义：过去完成时是一个相对的时态，表示的时间是过去的过去。
只有和过去某时或某动作相比较时才用到这个时态。
这个时态常常用于宾语从句中。
构成：主+had+过去分词我们可以用time line来比较过去完成时与一般过去时的不同，也比较两种时态。
1.He said he had been to Hawaii twice.2.They wondered if the bus had gone.3.By the end of last year, he had learned 1000 English words .4.He had gone to England before 2000.5.When I got there, Mr. Li had left .一．过去完成时的判断依据1. 由时间状语来判定一般说来，各种时态都有特定的时间状语。
与过去完成时连用的时间状语有：（1 ）by + 过去的时间点。
如：I had finished reading the novel by nine o'clock last night.（2 ）by the end of + 过去的时间点。
如：We had learned over two thousand English words by the end of last term.（3 ）before + 过去的时间点。
如：They had planted six hundred trees before last Wednesday.2. 由“过去的过去”来判定。
过去完成时表示“过去的过去”，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 ）宾语从句中当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。
过去完成时态
过去完成时态1.过去完成时态表示的含义：表示一个动作在过去某一时间或动作之前已经发生或完成（既一个动作发生在过去的过去）。
2.过去完成时态构成形式：had+过去分词3.过去完成时态的使用范围：✧出现在主从复合句中，常与that引导的宾语从句连用.例如：He said that he had never seen such a beautiful place before.(先看见过,再说)Lucy told me that she had been to Beijing twice.(先去过,再告诉我)✧出现在主从复合句中，常于when \ before \ after\as soon as 引导的时间状语从句连用.注意:主句和从句应各自拥有主\谓\宾的结构.例如: You had cleaned the classroom when I got here.My mother had cooked supper before I went home.Mr Liu had taught in the school for 38 years before I came here.I went to bed after I had finished my homework.注意: 在以上两种主从复合句中,经常存在两个动作,先发生的用过去完成时态,后发生的用一般过去时态.✧出现在简单句中, 常于by(表示在…之前\ 到…的时候) \ before 构成的时间状语连用.by, before +过去的时间点；例如: I had finished my homework by 11 last night.I had reached school before 7 o’clock this morning.✧出现在简单句中, 常于by the end of (到…末为止)引导的时间状语连用.例如:By the end of the match, we had scored 3 goals.We had learned 1000 English words by the end of last term.(到上学期末为止,既单词是在上学期末之前学的)✧与by the time (表示在…之前\ 到…的时候) 构成的短语连用,例如:By the time we got there, the bus had already gone.(当我们到那的时候, 车已经开走了).By the time they called, I had left.✧与as (表示象\ 按照) 引导的从句连用.例如;We did as he had told us.(我们按照他告诉我们的去做)4.过去完成时态的各种句式:否定句: had + not +过去分词或hadn’t +过去分词一般疑问句: 把had 提到句首.特殊疑问句: 疑问词+ 一般疑问句语序I had finished my homework by 11 last night. He had learned 1000 words by the end of last term.I hadn’t finished my homework by 11 last night. He hadn’t learned 1000 words by the end of last term.Had you finished your homework by 11 last night? Had he learned 1000 words by the end of last term?Yes, I had. No, I hadn’t. Yes, he had. No , he hadn’t.I had learned 4 songs by the end of last term. How many songs had you learned by the end of last term?5.过去完成时态应注意的几个问题:●在主从复合句中,如有after, before 引导的时间状语从句,由于从句的动作和主句的动作发生的顺序已经非常明显,有时可用一般过去时态代替过去完成时态.例如: He called me after he had come back..=== He called me after he came back.●对于一连串的过去动作,相互之间衔接十分紧密, 可以全部使用一般过去时态,不用过去完成时态.例如:He got up at six yesterday, washed, brushed his teeth, went downstairs and then did morning exercises.1)Peter told us that he＿＿＿＿（finish）the work already.2)They＿＿＿＿＿(wait) for two hours when he＿＿＿＿＿(come).3)When we got to the station, the train＿＿＿＿＿(leave) already.4)She made a lot of friends after she＿＿＿＿＿(study) in this school for three months.5)He said that he＿＿＿＿＿＿(not go)on the trip with us because he ＿＿＿＿＿(be) there twice.6)We＿＿＿＿＿＿(learn) more than 700 words by the end of last year.7)Ted went to the class again to get the book he ＿＿＿＿＿(leave) there.8)By the end of last week we＿＿＿＿＿(plant) 400 trees in our school.9)He said that Mary ＿＿＿＿＿(go) to London next month.。
