五年级上册第一、二单元语法there be句型专项讲解

there be句型的基本结构为：There + be ( is , are ) +主语+地点状语(在 ....... 地方)。意思是:在某个地方有某人或某物。

1肯定句形式为：

I is +可数名词单数/不可数名词+地点状语

There are +可数名词复数+地点状语

例: There ___ (be) some milk in the glass.

There ___ (be) some apples in the tree.

There _____ (be) a book on the desk.

There _____ (be) a lot of books on the desk.

There ___ (be) a pair of shoes un der the bed.

2、肯定句改为否定句分两步：

1) 在be (is/ are )动词后加not。即：is 改为is not (isn ') ；are 改为are not (aren't)

2) 若句子中有some 一定要改为any,其他内容不变。

例一：There is a dog in front of the house。(改为否定句)

There _____ a dog in front of the house。

例二：There are some dogs in front of the house。(改为否定句)

There _____ _____ dogs in front of the house。

练习：There are some build ings in the school. (改为否定句)

There _____________ buildi ngs in the school.

★ there be就近原则：如果there be句型中有几个并列主语时，be动词的形式要与离其最近的一个主语在数上保持一致。

例:There ____ (be) a pie and two hamburgers on the plate.

There ______ (be) two hamburgers and a pie on the plate.

There _____ (be) some milk and apples in the fridge.

There _____ (be) some apples and milk in the fridge.

3、there be句型的一般疑问句修改步骤(五步) ：

(3) 有some 变为any。

(4) 第一人称变为第二人称：I / we T you ; my / our 宀your ; me / us you

(5) 句号变问号(？)，肯定回答用：Yes, there is/are.否定回答用：No, there isn '/are n't. 例：There are some girls in the room .(改为一般疑问句，并作肯定回答与否定回答)

// / ,

Are there any girls in the room ? Yes, there are . / No , there aren t.

练习：1) There is an apple on the table.(改为一般疑问句，并作肯定回答与否定回答)
