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：
There are fifty-two students in our class.
There is a pencil in my pencil-case.
There was an old house by the river five years ago.
二、各种句式：
否定句：There be句型否定句式的构成和含有be动词的其它句型一样，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）。注意：no + n.（可数名词单数）= not a\an + n.（可数名词单数）；no + n.（可数名词复数）= not any + n.（可数名词复数）；no + n.（不可数名词）= not any + n.（不可数名词）。例如：
There is an orange in her bag.
→There isn’t an orange in her bag.
→There is no orange in her bag.
There are some oranges in her bag.
→There aren’t any oranges in her bag.
→There are no oranges in her bag.
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：
　　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.)
There is something new in today’s newspaper.
→There isn’t anything 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：
    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?
