高中英语时态 专题讲解

时态是英语谓语动词的一种形式,表示动作发生的时间和所处的状态.英语中的时态是通 过动词形式本身的变化来实现的.英语有16种时态,但中学阶段较常用的有十种:一般现在时,一般过去时,一般将来时,过去将来时,现在进行时,过去进行时,将来进行时,过去完成时,英在完成时和现在完成进行时. 1.一般现在时的用法 1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用。时间状语: every..., sometimes, at..., on Sunday。例如: I leave home for school at 7 every morning. 每天早上我七点离开家。 2) 客观真理,客观存在,科学事实。例如: The earth moves around the sun. 地球绕太阳转动。 Shanghai lies in the east of China. 上海位于中国东部。 3) 表示格言或警句。例如: Pride goes before a fall. 骄者必败。 注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。 例:Columbus proved that the earth is round. 哥伦布证实了地球是圆的。 4) 现在时刻的状态、能力、性格、个性。例如: I don't want so much. 我不要那么多。 Ann writes good English but does not speak well. 安英语写得不错,讲的可不行。 比较:Now I put the sugar in the cup. 把糖放入杯子。 I am doing my homework now. 我正在做功课。 第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
