发布时间:2014-01-28 13:47:19  

语法学习:复习一般现在时和现在进行时。

一般现在时:1. 区别含有be动词和行为动词的肯定句式。

I am at home.√ I stay at home.√ I am stay at home. × She stay at home. ×

Do you stay at home? I don’t stay at home. Does she stay at home? Yes, she does. No, she doesn’t. She doesn’t stay at home. 2. 一般疑问句、否定句表达的不同方式: Are you at home? I am not at home. Yes, I am. No, I am not. Yes, I do. No, I don’t.

3. 主语为第三人称单数时,谓语行为动词的变化。

1)She computer games on Sundays. 2)She English every morning.

3)She 4)She breakfast at 6:45.

4. 用法:(1) 表示现在的状况:I am a teacher. You are student. They are in London.

(2) 表示经常的或习惯性的动作:I usually go to school on foot. She plays tennis every morning.

(3) 表示主语具备的性格和能力等:He likes playing basketball. They do the cooking.

现在进行时:

1. 基本句式结构:I am playing with a computer.

2. 现在分词构成法:

go– going play – playing run– running have – having drive– driving swim – swimming begin – beginning

3. 用法:

(1)表示现在正在进行的动作:She is having dinner. 她正在用餐。

3. 与have的区别注:但在表示 "附属于某物/某处的东西"时,there be结构与have句型都可以用。如: There are four windows in the classroom =The classroom has four windows.

The house has eighteen floors.=There are eighteen floors in the house.

三、动词的一般过去时态

I. 一般过去时表示过去某个时间发生的动作或存在的状态。常和表示过去的时间状语连用。如:last year, yesterday等;也可表示过去经常反复发生的动作,常和often, always等频率副词连用。 例如:①I saw him in the street yesterday. 昨天我在街上看见他了。②Li Mei always went to school on foot last year. 去年李梅总是步行上学。

II.动词过去式的构成:(1)规则动词过去式的构成有四条规则:

①一般在动词原形末尾直接加上-ed。如:look-looked。

②以不发音的字母e结尾的动词,去e再加-ed。如:live-lived。

③末尾只有一个辅音字母的重读闭音节,先双写这个辅音字母,再加-ed。如:stop-stopped。

④末尾是辅音字母+y结尾的动词,先变y为i,然后再加-ed。如:study-studied。

(2)不规则动词的过去式需特殊记忆。如:am(is)-was, are-were, go-went, come-came, take-took,have (has)-had等。 III. 一般过去时的几种句型

:肯定句结构为:主语+动词的过去式+其它。如:He went to the toy store yesterday. 他昨天去玩具店了。

否定句结构为:主语+did not (didn't)+动词原形+其它:He didn't go to the toy storeyesterday. 他昨天没去玩具店。 一般疑问句的构成:Did+主语+动词原形+其它?如:

1) --Did you go to Beijing last week? --Yes, we did. (No, we didn't.)

2) --Did you meet the businessman before? --No, I didn't. (Yes, I did.)

特殊疑问句的构成: 疑问词+did+主语+动词原形+其它?如:

1) --What did you do last night? --I did my homework.

2) --Where did you go last week? --I went to Shanghai with my parents.

一般过去时口诀:一般过去时并不难,表示过去动作、状态记心间。 动词要用过去式,时间状语句末站。 否定句很简单,didn't 站在动词原形前,其它部分不要变。一般疑问句也好变,did放在句子前,主语、动词原

形、其它部分依次站。特殊疑问句也简单,疑问词加一般疑问句记心间,最后一条请注意,动词过去式要牢记。
