【篇一】

There be句型知识点

(1)There be句型主要用以表达“某处(某时)有某人(某物)。”其基本结构为“There be+某物(某人)+某地(某时)”其中there是引导词,没有词义;主语是be后面的名词, be是谓语动词,在一般现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构:

There be放句首,主语跟在后。地、时放句末,强调置前头。如:There is a book on the desk.有时为了强调地点,也可把介词短语放在句首。如:

On

the desk there is a book.

(2)There be句型中的be动词如何确定呢?请先看看下面这首歌诀:Be动词,有三个,am,is还有are。“There be”真特别,不留am只留俩,那就是is还有are。要用is还是are,须看其后的名词是单数还是复数。若是单数或不可数名词用is,否则就用 are。如:①There is a tree behind the house.②There is some water(水)in the bottle(瓶子).

③There

are some pears in the box.

(3)注意:如果“be”后的主语是由and连接的两个或两个以上的名词,那么be的形式要遵循“远亲不如近邻”的原则。也就是说,“be”的形式是 由与它最近的那个名词来确定的。若那个名词是单数或不可数名词要用is,是复数就用are。如:①There is a book and some pens on the floor.②There are some pens and a book on the floor.

【练习题】

用is或are填空

1.There________many monkeys in the mountain. 3. There _________some water in the glass. 5. _________there any maps on the wall? 7. There__________a bird in the tree. 9. ________there a cup of tea on the table? 11. There_____a bed and two chairs in Betty's room. 13. There __________some children in the park.

【篇二】

this,that和it用法

(1)this和that是指示代词,it是人称代词。

(2)距离说话人近的人或物用this, 距离说话人远的人或物用that。如: This is a flower. 这是一朵花。(近处)

That is a tree. 那是一棵树。(远处)

(3)放在一起的两样东西,先说this, 后说that。如:

This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。

(4)向别人介绍某人时说This is…, 不说That is…。如:

This is Helen. Helen, this is Tom. 这是海伦,海伦,这是汤姆。

(5)This is 不能缩写, 而That is可以缩写。如:

This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。

(6)打电话时,介绍自己用this, 询问对方用that。如:

-Hello! Is that Miss Green? 喂,是格林小姐吗?

-Yes, this is. Who’s that? 是的,我是,你是谁?

注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:I am…, Are you…?/Who are you?

(7)在回答this或that作主语的疑问句时, 要用it代替this或that。如:

①-Is this a notebook? 这是笔记本吗?

-Yes, it is. 是的,它是。

②-What’s that? 那是什么?

-It’s a kite. 是只风筝。
