动词时态
动词的时态
备考要点:英语中常用的时态有12种。在英语(一)考试的词形填空题中,经常被测试的动词时态有:一般现在时、一般过去时、一般将来时、现在进行时、现在完成时、过去完成时,且题目中一般都有明显的时间暗示。
特别提示:
1)特殊记忆一些不规则动词的过去式和过去分词。
2)特殊记忆一些暗示一般现在时、一般过去时、现在完成时和过去完成时等时态的时间状语。具体如下:
一般现在时
1) 一般现在时常与often, always, usually, sometimes, everyday, once a week等时间状语连用。
2) 一般现在时表示客观事实或普遍真理。
3)第三人称单数作主语时,动词后要加-s
标志词:often, always, usually, every day, once a week

1)现在完成时不能使用明确表示过去时间的状语,例如:yesterday, last week, in 1993等。

3)现在完成时常和since引导的短语或从句,或由for引导的表一段时间的短语连用。
