卓越教育老师为大家整理了相关资料,以供参考。 时态问题在英语中并不那么容易让人区分,而丢分项绝对离不开这里面的“布局”。初中所学的八大时态较之于以下提及的几点来讲,只有抓重点,难点,才能将此项的分囊括手中。一起来学习下昝翼的语法课吧~ 对于搅乱自己思绪的时态而言,做题的时候就像是丈二和尚——摸不着头脑。如何掌握好易混的时态?首先还是来看看易混的症结点在哪,才可以对症下药呀。 易混的时态无非是一般过去时和现在完成时,一般过去时和过去完成时的比较罢了。这有何难?看看下面的分析,你会发现一切'as easy as A B C'。 一般过去式和现在完成时:一般过去式只是表示事情发生在过去,陈述一个事实,它可以和确定的表示过去的时间状语如:last night, in 1999, three days ago等连用。而现在完成时表示某一完成的动作对现在造成的影响或结果,强调的是现在的情况,所以它不能和确定的表示过去的时间状语连用。 如: We have seen that film. 我们已看过那部电影。 对现在造成的影响是我们对影片已有所了解。 We saw the film last night. 昨天晚上我们看了那部电影。只说明昨天晚上看电影这一事实。注意:有些时间状语,如this morning,tonight, this month 等,既可用于一般过去时,又可用于现在完成时,但所表达的意义有所不同。用于现在完成时表示包括现在在内,而用于一般过去式则与现在无关。如: I have read this book this April.(说话时仍然为四月。) I read this book this April. (说话时四月份已过。) 一般过去式和过去完成时的比较: 一般过去式表示过去时间发生的动作或存在的状态,而过去完成时在过去某一时间或动作之前已完成的动作或状态,即'过去的过去'。当强调过去某一动作发生在某一动作之前时,常用此时态。 如: He had finished his homework before nine o'clock. 九点之前他已经完成了作业。实际上,一般现在时和过去完成时常搭配使用。如: When he got home, his daughter had already gone to bed. 当他到家的时候,他的女儿早已去睡觉了。 在带有after和before引导的时间状语从句的复合句中,由于从句的动作和主句的动作发生的先后顺序已经非常明确,所以可以用一般过去时代替过去完成时。 如:He called on me soon after he had finished his homework. 他做完作业后不久便来拜访我。也可以说: He called on me soon after he finished his homework. 练习: 1.
