I was watching TV. 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 was((were)doing did did was((were)doing 连词 when when while while 从句时态 did was((were)doing was((were)doing 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. 过去举行时态与一般过去时的识别在于：前者表示一个动作正在举行，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”（鲜明已经读完了） (2) 时态 The Present Perfect Tense 现在完成时态 1.表示过去发生或已经完成的动作对现在造成的影响或结果 2.表示过去已经开头持续到现在的动作或状态 常与之连用的词或短语 just, yet , already, ever, never, before 等 动词形式 Have +done has 例句 Have you finished your homework yet? Yes, I have already finished it. I have lived in Tianjin for three years. He has worked in this factory since 1990. from then on, all one’s life, these days, for+一段时间 since+时间点或从句 Have + done has 注：1. 现在完成是与一般过去时的识别： 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，后者那么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） 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，其谓语动词也务必是持续性的 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 现在完成时的否决形式可与for或since连用。
