第二篇:各种时态归纳总结
容易混淆的几个时态归纳总结
一. 一般过去时
一般过去时:主要表示过去的动作或状态。构成:主语+动词过去式 基本用法:
A:带有确定的过去时间状语时,要用过去时。也就是一些标志词:
yesterday, last year, once upon a time (过去曾经), in the old days, when I was 8 years old= at the age of 8, 时间段+ ago (two hours ago), just now (刚才), before two days, the other day (几天前)
B:表示过去一段时间内经常或反复的动作。常与always, never 等连用。
1. Mr Peter always carried an umbrella. (只是说明他过去的动作,不表明他现在是否常带雨伞)
2. I never drank wine. (我以前从不喝酒。)
二.现在完成时
现在完成时:表示过去发生的动作,并对现在有影响。
构成:have/has +动词过去分词
基本用法:
A:标志词:already, yet (用在疑问句或否定句中), just, recently, ever, never, before, these days, all this year, for+时间段, so far, since then, in the last few years, up to now, until now (直到现在) , since+时间点(高频考词) I have worked in our school for 8 years.
I have worked in our school since 20xx. = Since 20xx, I have worked in our school.
He has worked in the hospital since he came to Chengdu. = Since he came to Chengdu, he has worked in the hospital.(注意since前后的时态、位置和标点符号。)
B:注意:have been to 和 have gone to 的区别
have been to: 指“曾到过某地”,说话时此人已经回来,在说话现场,而侧重指经历 I have ever been to America. It’s a developed country.
have gone to: 指“已经去了某地”,说话时此人不在说话现场,或在去的途中或是已到达目的地。A: Excuse me. Where is Mr Green? B: He is not in the office. He has gone to library. C: 注意该时态在近几年的中考题里喜欢考瞬间动词和延续性动词的转换。
