一、一般现在时:

概念:经常、反复发生的动作或行为及现在的某种状况。

时间状语:always, usually, often, sometimes, every week (day, year, month…),

once a week, on Sundays, etc.

基本结构:①be动词;

②行为动词

否定形式:①am/is/are+not;

②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。

一般疑问句:

①把be动词放于句首;

②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。

在中,当主语是时,谓语动词要用形式,即常在后加-s或-es。

一、he, she, it是第三人称单数。如:

He likes watching TV. 他喜欢看电视。

She has lunch at twelve. 她十二点吃午餐。

It looks like a cat. 它看起来像只猫。(口诀:I用am,you用are,is用于它,单数名词用is,都用are)

二、单个人名、地名或称呼作主语;是第三人称单数。如:

①Han Mei looks like her mother. 看起来像她的母亲。

②Beijing is in China. 北京在中国。

2 / 37

③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。

三、单数可数名词或"this / that / the+单数可数名词"作主语时,是第三人称单数。如:

①A horse is a useful animal. 马是有用的动物。

②This book is yours. 这本书是你的。

四、someone, somebody, nobody, everything, something等及指示代词this,

that作主语时,是第三人称单数。如:

①Everyone is here. 大家到齐了。

②There is something wrong with the watch. 这块手表有毛病。

五、作主语时为第三人称单数。如:

①The milk is in the glass. 牛奶在里。

②The bread is very small. 那面包很小。

六、当数字或字母作主语时,看作第三人称单数。如:

时间状语:ago, yesterday, the day before yesterday, last week(year, night,

month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a

time, etc.

一般过去时的结构(可分三类不同的结构)

3 / 37

1.Be动词的一般过去时 在没有实义动词的句子中使用be动词, am is 的过去式为was; are的过去式为were

肯定句式:主语 + be(was , were) + 其它.

否定句式:主语 + be(was , were) + not + 其它.

一般疑问句:Be(was , were) + 主语 + 其它?

注:在这种构成中,be动词有人称和数的变化,即要根据主语选用was /

were。Be动词分为单数和复数,was是表示单数,were是表示复数。

2.实义动词的一般过去时态 肯定句要使用动词的过去式,否定句和疑问句要使用助动词do和 does 的过去式 did.

肯定句式:主语 + 动词(过去式)+ 其它

否定句式:主语 + didn’t + 动词(原形)+ 其它 【did not = didn’t】

一般疑问句:Did + 主语+ 动词(原形)+ 其它【do , does的过去时均为did】?

注:1. did和didn’t是构成一般过去时的助动词,其特点是要在其后跟动词的原形。

2. 实意动词do的一般过去时

I do my homework every day.(用yesterday改写句子)

I did my homework yesterday.

I didn’t do my homework yesterday.(否定句)

Did you do your homework yesterday?Yes ,I did. /No, I didn’t.(一般疑问句)

3. 情态动词的一般过去时态 含有情态动词的一般过去时与含有Be动词的一般过去时,是十分相似,请注意观察。

4 / 37

肯定句式:主语 + 情态动词 + 其它

否定句式:主语 + 情态动词 + not + 其它.

一般疑问句:情态动词 + 主语 + 其它?

注:情态动词的过去式:can→could , may→might , must→must ,will-would,should-should。

4.特殊疑问句式: 特殊疑问词+be过去式+主语+其他?

特殊疑问词+情态助动词过去式+主语+动词原形+其他?

特殊疑问词+do/does过去式+主语+动词原形+其他?

What was your former name? 你以前叫什么名字?

Why was he late for school last Monday? 上星期一他为什么迟到?

What could she do twenty years ago? 20年前她能做什么?

规则动词的过去式
