中考网整理了关于2021年中考英语复习之过去完成时的语法判定,希望对同学们有所帮助,仅供参考。 过去完成时 3. 过去完成时的语法判定 (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: ①by + 过去的时间点 I had finished reading the novel by nine o’clock last night. ②by the end of + 过去的时间点 We had learned over two thousand English words by the end of last term. ③before + 过去的时间点 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。如told,said,knew,heard,thought等动词后的宾语从句。 She said that she had seen the film before. ②状语从句中 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。 After he had finished his homework, he went to bed. 注意:before,after 引导的时间状语从句中,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,则主、从句都用一般过去时。 After he closed the door, he left the classroom. ③表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本……,未能……"。 We had hoped that you would come, but you didn’t. (3)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. (责任编辑:admin) |
