六. There be结构

1. There be句型主要用以表达“某处有某人（某物），强调存在”其基本结构为“There be＋某物（某人）＋某地”，有时为了强调地点，也可把地点状语放在句首。

There is a book on the desk.

On the desk there is a book.

（1）肯定句：“There be+主语（某人/某物）+介词短语”

There are three people in my family. 我家有三口人。

There is a pen and two books on the desk. 书桌上有一支钢笔和两本书。

（2）否定式：“There be +not+主语+介词短语”

There isn’t a boy in the room.房间里没有一个男孩。

There aren’t any books on the desk.书桌上没有书。

注意：“There be句型”的否定式的构成和含有be动词的其他句型一样，在be后加not或no即可。the piano

注意not和no的不同：not是副词，no为形容词，所以not a/an/any+n，相当于no+n。

There aren’t any pictures on the wall.

=There are no pictures on the wall.

There isn’t a bike behind the tree.

=There is no bike behind the tree.

（3）疑问式：Be there+主语+介词短语？”

肯定回答是：“Yes, there be.”否定回答是：“No, there+be与not的缩写形式”。

—Is there a lamp in your bedroom?在你的卧室里有台灯吗？

—Yes, there is.是的，有。

—Are there any clock in the living room?客厅里有钟吗？

—No, there aren’t.不，没有。

（4）特殊疑问句：一般有两种句型结构

How many+复数名词+are/were there+介词短语？

There’re many children in the park.

How many children are there in the park?

How much+不可数名词+is/was there+介词短语？

There was little rain around the year.

How much rain was there around the year?

2. have表示“某人拥有某人或某物，强调拥有和所属关系”。

The man has two cars.

3. There be句型中的就近原则，即be和距其最近的主语保持一致。

There are some pens and a book on the floor. =There is a book and some pears on the floor.

七. 选择疑问句

选择疑问句是指说话人提出两种或以上的情况，让对方选择是哪一种，两个选择部分用or连接。选择疑问句不用yes或no来回答，直接在两个选择里选一个回答。
