一般现在时基本用法

1.一般现在时的构成形式如下:

肯定式疑问句否定式疑问否定式

I work Do i work ? I do not work Do i not work?

We work Do we work? We do not work Do we not work? You work Do you work? You do not work Do you not work? They work Do they work? They do not work Do they not work?

2.一般现在时的基本用法

①一般现在时常表示经常发生的动作或经常存在的状态

如:I go to school every day.

我每天上学。

②表示此状态时,常和always,often,usually,everyday,sometimes等表示时间的状语连用,有时候时间状语可以不表示出来

如:Where do you live?

你住在哪里?

③由when ,while,before,after,until,as soon as 等引导的时间状语从句亦可用一般现在时态表示经常发生的动作或是状态。

如:Make hay while the sun shines.

要趁热打铁

一般现在时常用于以下情况

表日常行为:

如:The boy wake up at seven a'clock,wash ,dress quickly and run into

the dining room for breakfast. They wait until they hear the bell and then go to school.

这些男孩7点起床,洗漱完毕,很快地穿好衣服,就到食堂去用早餐,然后等上课铃一响就去上课。

表习惯,能力等:

如:Do you drive, Joho?

Joho,你会开车吗?

表客观存在:

如:Fire burns

火会燃烧(表客观事实)

The earth moves round the sun.

地球围绕太阳旋转(表客观真理)

报纸,杂志,书籍不强调过去时间,单纯表示客观事实(即所载文字依然存在)时候,也可用一般现在时态

如:What does the newspaper say? (是什么时候的练习题目吧)今天报纸说些什么?

二、单三人称形式易出错

例:1 He plaies (play) football very well.

2 Danny gos (go) to school at 7:10.

答案:1 plays 2 goes

解析:1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es;2与名词变复数不同,变单三人称形式以o结尾的词要加es.

三、在句式变换时易出错

例:1 Does Jenny has (has) a good friend?

2 Brian doesn’t lives (not live) in China.

答案:1 Does have 2 doesn’t live

解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:“见助动,用原形”。此口诀也可推广用于一般过去时态中。e.g. He didn't go home yesterday.

四、对do的理解易出错

例:We don’t (not do) our homework in the afternoon.

答案:don’t do

解析:do是一个比较难理解的词,它有三个含义:

a)是所有行为动词的总称;b)是助动词,无实义;c)是一个具体的行为动词“做,干”。此句中给出的do指“做,干”,not指把此句变为否定句,故须在do 前加助动词don’t。

五、对主语的数判断有误

例:Li Ming with me are (be) in Beijing.

答案: is

解析:表面一看是“我和李明两个人在北京”,但with在此做伴随状语,不能做主语,故用is.

另外,宾语从句中,从句部分若是表示客观真理,不管主句是何时态,从句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般现在时。
