1、对主语提问：当主语是人时，用 “Who’s + 介词短语?”；当主语是物时，用 “What’s + 介词短语?”。其中there在口语中常常省略。注意：无论原句的主语是单数还是复数，对其提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如：
There is a bird in the tree. →What’s in the tree?
There are some bikes over there. →What’s over there?
There is a little girl in the room. →Who is in the room?
2、对地点状语提问：用 “Where is \ are + 主语?”表示（注意其答语变化）：例如：
There is a computer in my office.
→ Where is the computer? ----It’s in my office.
There are four children in the classroom.
→Where are the four children?—They’ re in the classroom.
3、 对数量提问：一般有两种提问方式：
如果主语是可数名词，无论是单数还是复数，都用“How many +可数名词复数+ are there + 介词短语？”表示：
There are twelve months in a year.
→How many months are there in a year?
There is only one book in my bag.
→ How many books are there in your bag?
There is a cat in the box.
→ How many cats are there in the box?
如果主语是不可数名词，则用“ How much + 不可数名词 + is there + 介词短语？”表示：
There is some money in my purse. How much money is there in
your purse?
反意疑问句：There be或There加其它动词，其反意疑问句一律用…there?例如：
There is a beautiful girl in the garden, isn’t there?
There used to be no school here, used there \did there?

注意事项：
1、There be句型中be动词的形式要和其后的主语在人称和数上保持一致。
如果句子的主语是单数的可数名词，或是不可数名词，be动词用“is”“was”。例如：
There is a basketball in the box.
There is a little milk in the glass.
如果句子的主语是复数名词，be动词就用“are” “were”。例如：
There are many birds in the tree. There were many people in the street yesterday.
如果有两个或两个以上的名词作主语，be动词要和最靠近它的那个主语在数上保持一致，也就是我们常说的 “就近原则”。例如：
There is an orange and some bananas in the basket.
There are some bananas and an orange in the basket.
2、There与be中间可插入一些表推测的情态动词、表时态的短语和一些动词短语 (如和将来时be going to\ will、现在完成时 have\has + pp、used to结构等连用，注意其构成形式,这一内容在我们日常练习中经常出现错误,是一难点,也是历年中考试题中的一个考点.)。例如：
There must be a pen in the box.
There happened to be some money in my pocket.
There is going to be a meeting tonight.
There has been a big tree on the top of the hill.
There used to be a church across from the bank.
3、There be句型和have\has的区别：
There be句型表示 “存在有”, have\has表示 “拥有” “所有”,两者不能同时使用.例如：
桌子上有三本书. There are three books on the desk.
我有三本书. I have three books.
4、 There be + 主语 + doing +介词短语. 例如：
There is a truck collecting rubish outside.
There is a wallet lying on the ground.
举例
There are two dogs in the garden.
There weren't any people in the park yesterday.
There won't be another football match next Sunday.
There have been some changes since you left last week. There is a book on the desk.
There can't be anything new.
Must there be an indefinite article here?
Is there going to be a post office in the village?
There is a great Italian deli across the street.
There are some students in the dormitory.
