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) 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。
