Unit3 There be 句型一、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 )+名词+地点状语。
例如：1) There are fifty-two students in our class.2) There is a pencil in my pencil-case.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：T here 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 somethin g 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?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.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 two bananas in the basket.6) There are two bananas and an orange in the basket.2．There be +名词+地点/时间状语There was a party in the hall last night.3．由there be构成的固定句型There is something wrong with … = Something is wrong with …There is something wrong with my bike. = Something is wrong with my bikeThere is\are sb \sth doing sth .There is a bird singing in the tree.4. 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：1)The tree has many apples on it.2)There are many apples on the tree.3)There have many apples on the tree.(×)4)There’s a picture on the wall.5)There are six rooms in this house.There be 句型专项练习一、用be的正确形式填空1.
