Language Points

【知识考点一】
There be句型

 (一)：there be 句型基本认识

 1、 定义：There be句型表示某处存在某物或某人。

 2、结构：(1) There is +单数可数名词/不可数名词+ 地点状语.

          (2) There are +复数名词+地点状语.

注意事项：there是引导词，在句中不充当任何成分，翻译时也不必译出。句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。

e.g ①There is a bird in the tree. 树上有一只鸟。

   ②There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。

   ③There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。

 (二)：there be 句型的常考点

1：变成否定

There be句型的否定式的构成和含有be动词的其它句型一样，在be后加上not即可。

   e.g(1)： There are some pictures on the wall.（变为否定句）

           _______________________________________________________________   

   e.g(2)： There is a bike behind the tree.（变为否定句）

           _______________________________________________________________

2：变成一般疑问句

   There be句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可。但同时要注意：当肯定句中有some时，要将其改为any（否定变化也一样）。

some 用于肯定句， any用于否定或疑问句。

e.g(1).There is some water on Mars. → ______ ______any water on Mars?

   (2)There are some fish in the water. →______ _______ ______ fish in the water?

3：特殊疑问句

   对主语提问：当主语是人的时候，则用who 引导，当主语是物的时候，则用what 引导。注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。

e.g(1).There are many things over there. →What's over there?

  (2) There is a little girl in the room.→Who is in the room?

对地点状语提问：则用where 引导。

e.g (1)There is a computer on the desk. → Where ______ the computer?

   (2)There are four children on the playground. →Where _______the four children?

 对数量提问：般有两种句型结构：

 How many+复数名词+are there+介词短语？

 How much+不可数名词+is there+介词短语？

 e.g 你的教室有多少张桌子？

____________________________________________________________________________

桌子上有多少面包？

____________________________________________________________________________

【知识考点二】

 There be 句型与have / has 的区别

 1、There be句型表示某处存在某物或某人，而have / has 表示主观上的“拥有；持有”，表示

    某人拥有某物，是一种所属关系。

 2、结构：主语 + have（第三人称单数用has）+ 物品

    e.g：I have some apples.

        My mother has some friends.

 3、have/has跟主语的搭配

     第一人称：我，我们 I, we

     第二人称：你，你们 you

     第三人称：除第一、第二人称之外的其他人称

     第三人称单数：he, she, it, Kitty, Alice, Ben....

     have(第三人称单数)——has

 【试试看】

  请用“have, has”;“there is , there are”;“is there”;“are there”填空 。

  1. I________a good father and a good mother.

  2. ____________a telescope on the desk. 

  3. He_________a tape-recorder.

  4. _____________a basketball in the playground.

  5. She__________some dresses.

  6. They___________a nice garden.

  7. What do you___________?

  8. ______________a reading-room in the building?

  12. _______________a story-book on the table.

  13. _______________any flowers in the vase?

  14. How many students____________in the classroom?

  15. My parents___________some nice pictures.

Fun with Culture

    英文中的绕口令非常有趣，例如：A big black bug bit a big black bear and made the big black bear bleed blood.一只又大又黑的虫虫咬了一只又大又黑的熊，使得这只又大又黑的熊流血了。这句绕口令读起来是不是很有趣呢？试试这句：Fresh fried fish, fish fresh fried, fried fish fresh, fish fried fresh. 你知道这句话是什么意思吗？
