八年级英语练习题 Unit 4—Unit 7 Grammar: Tense时态： （1） 时态 常与之连用的词或短语 动词形式 例句 The Past last night, was +doing What were you Continuous Tense at this time were doing at this time yesterday, yesterday? 过去进行时态 I was watching （表示在过去某at 6:00 yesterday. TV. 一时刻或某一般morning, from 4:00 to 6:00 时间内正在进行yesterday 等 或发生的动作） when 与 while 引导的时间状语从句中，主从句的几种时态搭配关系。 主句时态 连词 从句时态 was((were)doing when did did when was((were)doing did while was((were)doing was((were)doing while was((were)doing 例句：1.My mother was washing clothes when I got home yesterday. 2.Tom came to my house when I was doing my homework. 3.While some of the students were stopping the traffic the boys carried the man to the gate keeper’s room 4.Mary was dancing while Peter was playing the piano. 过去进行时态与一般过去时的区别在于：前者表示一个动作正在进行，后者表示一个动作已经完成。例如： 1. I was reading a book last night. 2. I read a book last night. 句1译为“昨晚我在读一本书”（可能没有读完），而句2的意思是“昨晚我读了一本书”（显然已经读完了）。 (2) 常与之连用的词或时态 动词形式 例句 短语 The Have +done Have you finished 1.表示过去发生just, yet , already, Present your homework yet? 或已经完成的ever, never, before has Perfect Yes, I have already 动作对现在造等 Tense finished it. 成的影响或结现在完成时态 果。 Have + done I have lived in Tianjin 2.表示过去已经from then on, has for three years. 开始持续到现all one’s life, He has worked in this 在的动作或状these days, factory since 1990. for+一段时间 态。 since+时间点或从句 注：1. 现在完成是与一般过去时的区别： 现在完成是与一般过去时都是动作发生在过去，但前者强调发生的动作对目前的影响，后者则只是对动作发生的叙述而已。例如： He went to his brother at 3 in the afternoon. 他是在下午三点钟去他兄弟那里的。（强调下午三点发生的动作） 1 / 3 He has gone to his brother for his book. 他已经上他兄弟那里拿书去了。（强调现在他不在这里） 2．与for 介词短语和since 介词短语或状语从句连用的现在完成时，其谓语动词也必须是持续性的。 非持续性动词的处理：将其改为表示状态的形式 如：come back 改为be back He has come back. He has been back for three days. 其他非持续性动词的处理方法： leave—be away from open—be open die—be dead close—be closed fall asleep—be asleep join—be a member of begin—be on get up —be up arrive(get, reach) —be in buy—have borrow—keep 现在完成时的否定形式可与for或since连用。 例如：I haven’t seen him for a long time.
