There be句型的用法
一、构成：There be ...句型表示的是“某处有(存在)某人或某物”，其结构为There be(is，are，was, were )+名词+地点状语。例如：
1)T h e r e a r e f i f t y-t w o s t u d e n t s i n o u r c l a s s.
2) There is a pencil in my pencil-case.
3) There was an old house by the river five years ago.
二、各种句式：
否定句：在be后加上“not”,也可用“no”来表示。即：no + n.（名词）= not a\an\any + n.（名词）。例如：
1) There is an orange in her bag.
→There isn’t an orange in her bag.
→There is no orange in her bag.
2) There are some oranges in her bag.
→There aren’t any oranges in her bag.
→There are no oranges in her bag.
3) There is some juice in the bottle.
→There isn’t any juice in the bottle.
→There is no juice in the bottle.
一般疑问句：There be结构的一般疑问句变化只需把be动词移到句首，再在句尾加上问号即可。例如：
4) There is some money in her handbag.
→Is there any money in her handbag (疑问句和否定句中，some改为any, something改为anything.)
5) There is something new in today’s newspaper.
→Is there anything new in today’s newspaper
特殊疑问句：There be句型的特殊疑问句有以下三种形式
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：
6) There is a bird in the tree. →What’s in the tree
7) There are some bikes over there.
→What’s over there
8) 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：
9) There is a computer in my office.
→Where is the computer ----It’s in my office.
10) 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：
11) There are twelve months in a year.
→How many months are there in a year
12) There is only one book in my bag.
→How many books are there in your bag
13) 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：
14) 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：
15）There is a beautiful girl in the garden, isn’t there
16）There used to be no school here, used there \did there
三、用法：
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。
1)There is a basketball in the box.
2)There is a little milk in the glass.
3)There are many birds in the tree.
4)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：
5) There is an orange and some bananas in the basket.
6) 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(如和将来时be going to\ will、现在完成时have\has + pp. ) 例如：
1) There must be a pen in the box.
2) Is there going to be a dancing party tonight
3) There is not going to be a meeting tonight.
4) There has been a big tree on the top of the hill.
3. 英语中有些动词或短语具有一定的情态含义，我们称之为半助动词。There be句型中的谓语动词be可与这些半助动词连用，表达更为复杂的意念。能用于There be句型中的这类词语主要有：happen to（碰巧），appear ／seem to（似乎），used to（曾经），have to（必须），be likely to（很可能），be bound to（必定）等。例如：
1)There happened to be an
old friend of mine in the club
在那个俱乐部碰巧有我的一个老朋友。
2)There appear to be several reasons for changing our
plans．
看来改变我们的计划有几个理由。
