I/You/He/We/They had finished the work. 3、否定形式： had + not + 过去分词 例：She had not (hadn't) seen the film before. 4、疑问形式： Had + 主语 + 过去分词 + 例：Had you learned English before you came here 三、使用情景 1. 表示“过去的过去” By the end of last term, we had learned 2,000 English words.（到上学期末为止） He told me that he had read the book twice.（告诉我之前） 2. 与一般过去时动作对比（常与when, before, after等连用） When I got home, my parents had already had dinner. The film had already begun when we arrived at the cinema. 3. 用于宾语从句中（主句为一般过去时） He said (that) he had never been to Beijing. I thought I had seen her somewhere before. 4. 表示“原本打算/希望做但未做成”（had hoped/planned/intended等） I had hoped to see you, but I was too busy. They had planned to go hiking, but it rained. 四、时间状语特征 1、by短语（到...为止） by the end of last year/month by yesterday/then 例：By 2020, he had worked here for 10 years. before短语（在...之前） 2、before yesterday before 9 o'clock last night 例：He had finished his homework before dinner. 3、when/before/after引导的时间状语从句 When I called him, he had gone out. After they had left, we cleaned the room. 4、already, yet, just, ever, never等副词 She had already left when I arrived. I had never seen such a beautiful place before. 五、句法要点 1. 与一般过去时的区别 一般过去时 过去完成时 表示过去发生的动作 表示过去某一时间之前已发生的动作 有明确的过去时间 时间相对模糊，是“过去的过去” 例：I saw the film yesterday. 例：I had seen the film before yesterday. 2. 在复合句中的应用 When从句： When I arrived, the meeting had started.（我到时会议已开始） When I arrived, the meeting started.（我到后会议开始） Before从句： He had left before I arrived.（我到之前他已离开） After从句： After he (had) finished his work, he went home.（过去完成时可省略） 3. 与现在完成时的对比 现在完成时 过去完成时 与现在有关 与过去有关 have/has + p.p. had + p.p. 例：I have read the book. 例：I had read the book before last week. 六、常见错误提醒 1、滥用过去完成时 He had finished his work yesterday.（有明确过去时间yesterday） He finished his work yesterday. 2、had与would混淆 I would finished the work before he came. I had finished the work before he came. 3、忘记用过去分词 They had finish their homework by 9 pm. They had finished their homework by 9 pm. 4、时间先后顺序错误 After he had gone to bed, he read a book.（逻辑错误） After he had read a book, he went to bed. 1．When I got up early the next morning, John and his wife_____ to work. A．went B．has gone C．have g ... ...
