初一英语需要补充的一个重要句式就是There be句型

一、There be句型

I. 定义与概念

定义：人或事物的存在，there作为引导词，无实际意义。There be句型属于倒装结构。

II. There be句型的转换

1、 否定句：在be动词后面加no或者not

I、关于no的否定：no后面可直接加名词

There is no water in the bottle.

There are no apples on the table.

II、关于not的否定：not后面不能直接加名词，必须要接冠词或形容词来修饰。

There isn’t a box in the room.

There are not any pens on the desk.

2、 疑问句：将be动词，助动词或情态动词提前，回答用yes或no，后接简单答语。

Is there a cake on the table?

Yes, there is. / No, there isn’t.

Will there be a party tonight?

Yes, there will. / No, there won’t.

III. 课堂过手练习

There ___ ___ boats on the lake. (否定句)

There ___ ___ ___ boats on the lake. （否定句）

There is some rice in the bag.

（改为一般疑问句）_______________________________

Ⅳ. There be 句型的两大原则

1、主谓一致：当be动词后所接名词是可数名词单数形式或不可数名词时，be应使用单数；当be动词后所接名词是可数名词复数形式时，be应使用复数。

There is a man at the door.

There is some milk in the cup.

There are many people in the classroom.

2、就近原则：当be动词后面有几个并列名词做主语时，动词be的形式和最靠近它的那个名词保持数的一致。

There is a pen and two books on the desk.

There are three singers, five workers and a teacher on the playground.

课堂知识过关

There _______ (be) two thousand students in our village.

There _______ (be) a writer and singer in our school last week.

There _______ (be) sheep and goats on the hill yesterday morning.

There _______ (be) some food in the box.

There _______ (be) five hundred dollars to pay.

There _______ (be) still another 20 miles to drive.

Ⅴ. There be 句型的时态

注意be动词的变化形式

There are some strangers in the street. （一般现在时）

There was a football match in our school yesterday. （一般过去时）

There stands a big tall apple tree in front of my house. （对其他动词的变形）

Once there lived an old fisherman near the sea. （对其他动词的变形）

There will be a meeting in three days.(一般将来时）

【过手知识过关】

Look! There _______ (come) the No.7 bus.

Once there _______ (live) some hard-working people in the forest.

_______ there _______ (stand) a statue (雕像) by the sea?

2、与情态动词连用：有时根据表达需要，可适当用些情态动词如can, may, must等，

构成There+ may/must/can/will +be

There must be something wrong with the computer.

There may be a meeting in the evening.

Ⅵ. There be与have的比较

1、区别：There be句型意为存在，强调某地有某物，不表示所属关系；而have表示所属关系，强调某人或某地有某物。

There are some trees in front of the house.

I have many friends in China.

2、相同点：在表示结构上的含有时，两者都可以用。

There are many long rivers in China. / China has many long rivers.

How many days are there in May? / How many days does May have?

特别要注意：没有there have 这样的结构。
