初中英语语法总结——动词的时态

英语的时态主要体现在谓语动词上,用谓语动词的不同形式来表示。其意义主要是说明动作、状态发生的时间。下面我们分别来讲解:

(一) 一般现在时

1、一般现在时的用法

一般现在时主要用在以下几种情况下:

1) 表示经常性或习惯性的动作,常与表示频度的时间状语连用。如时间状语: every …, sometimes, at …, on Sunday等,例如:

I leave home for school at 7 every morning. 每天早上我七点离开家。

2) 表示客观真理、客观存在或科学事实。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。

(注:这种情况不会随时间的变化而变化,是客观存在的真理,所以用一般现在时就可以,不必使用其他时态。)

3) 表示格言或警句。例如:

Pride goes before a fall. 骄者必败。

注意:2)、3)的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。(分析:此句中that the earth is round是一个句子,作为大句子中proved的宾语,因此这个句子叫做宾语从句,而Columbus proved……为主句。可以看出,主句是用的过去时,而从句却用了一般现在时,因为从句是描述的一个永恒不变的真理,不随时间变化。)

4)表示现在时刻的状态、能力、性格、个性。例如:

I don't want so much. 我不想要那么多。

Ann writes good English but does not speak well.安英语写得不错,讲的可不行。

2、一般现在时在使用时要注意“三单形式”的变化。

即动词的主语为第三人称“他、她、它或针对一个人的人名、称呼等”(如he、she、it、Li Ming、My sister等) 的时候,动词要用第三人称单数形式。

三单动词的变化规则:

(1)一般情况下,直接加-s。

(2)以s. x. sh. ch. o结尾,加-es。

(3)以“辅音字母+y”结尾,变y为i, 再加-es。

3、一般现在时用法专练:

(1) 写出下列动词的第三人称单数

drink ________ go _______ stay ________ make ________

look _________ have_______ pass_______ carry ____

come________ watch______ plant_______ fly ________

study_______ brush________ do_________ teach_______

(2)用括号内动词的适当形式填空。

1)He often ________(have) dinner at home.

2) Daniel and Tommy _______(be) in Class One.

3)We _______(not watch) TV on Monday.

4) Nick _______(not go) to the zoo on Sunday.

5) ______ they ________(like) the World Cup?
