There Be 结构
“There Be…”的结构表示“存在”的一个特殊句型。该句型在使用时必须注意以下几点
1 “There be…”结构表示“某时，某地存在着什么事物或人”这个句子结构中there本身没有词义，be是谓语动词，be动词后面的是主语，这两者的数必须一致。句子的最后是地点或时间状语。
   例如： There is a book on the desk. 主语是 a book 单数因此谓语动词用is on the desk在课桌上就是地点状语。这几句的意思就是   “在课桌上有一本书。”
2 “There be…”结构的谓语动词be在人称和数上应与其后的主语保持一致。（也就是主语是不可数名词或可数名词的单数形式，谓语动词用is，主语是复数，谓语动词用are）
如： There is some water in the bottle.
           一些水（不可数名词）
    There is a pencil box in my schoolbag.
          一个铅笔盒（可数名词的单数形式）
    There are some books on my chair.
           一些书（可数名词的复数形式）
3 若句子中有几个并列主语，be的形式要与力气最近的一个主语在人称和数的形式上保持一致，也就是“就近原则”
如： There is a river, a small house and some green trees in the picture.
     There are some trees, a river and a small house in the picture.

There Be 结构的句型转换
1 如何转换成否定句
“There be… ”句型的否定式通常在be动词后加上not即可。（be动词通常会与not缩写在一起 is not写成isn’t，are not写成aren’t，如果句中有some ，改为否定句时要把some变为any。
如： There are some children in the picture. 画上有些孩子。
改为否定句：
There are not （aren’t） any children in the picture. 画上没有孩子。因此 There be 句型的否定结构是：
  There is/are not + 主语+ 地点状语。

2 如何转换成一般疑问句并做肯定和否定回答
“There be… ”句型的一般疑问句是把be动词is或are调到there的前面，首字母改为大写，句末句号改问号。口诀为“一调三改”
一调：be动词is或are调到there的前面
三改： 一改  调前的be动词is或are首字母改为大写。
       二改  原来首字母大写的There改为小写there
       三改  句末句号改成问好。
如：There is a map on the wall.改为一般疑问句
Is there a map on the wall？
肯定回答 Yes， there is.
否定回答 No， there isn’t.
★特别注意 如果句中有some在改为一般疑问句时要多加一改，即把some改为any。句中有some口诀为“一调四改”
如：There are some reading rooms in the building. 改为一般疑问句
    Are there any reading rooms in the building？
肯定回答 Yes， there are. 或Yes，there are some.   
否定回答 No， there aren’t. 或Yes，there aren’t any.
★总之 some只在肯定句中出现，any则用在否定句或疑问句中。

2 如何转换成特殊疑问句并做回答
  A 如果是对主语进行提问，也就是对be动词后面的部分进行提问，句型一律用 What’s（What is）+地点/时间状语？
如 There are lots of classrooms in the building. 对划线主语部分提问
   What’s in the building?
★不管句型是单数还是复数，问句一定要用单数形式即用What’s…?
B 如果对可数名词（主语）前的数量提问时，用how many，句型结构为
How many +复数名词+are there +其他部分？（主语不管是单数还是复数，特殊疑问句中的be动词一定是are）
如 There is a bed in my bedroom. 改为特殊疑问句即对划线部分——主语a bed前表示数量的a进行提问
  How many beds are there in your bedroom？
