例如：What’s in your room?---There is a bed, a desk and a chair in my room.What’s in your bag?---There are some books and a pen.2）巧问颜色----What colour...?句型结构：What colour is/are + 物品？例如：What colour is your computer? ---It’s pink.What colour are they? ---They are green.3、方位介词On表示“在...上面”。

All the students were very excited.否定句：________________________________________________ 一般疑问句：____________________________________________肯、否定回答：__________________________________________二、There be(一)：there be 句型基本认识1、定义：There be句型表示某处存在某物或某人。

2、结构：(1) There is +单数可数名词/不可数名词+ 地点状语.(2) There are +复数名词+地点状语.注意事项：there是引导词，在句中不充当任何成分，翻译时也不必译出。

句子的主语是某人或某物，谓语动词be要与主语（某人或某物）的数保持一致。

当主语是两个或两个以上的名词时，谓语动词要与跟它最近的那个名词一致。

如：①There is a bird in the tree. 树上有一只鸟。

②There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。

③There are two boys and a girl under the tree. 树下有两个男孩，一个女孩。

(二)：there be 句型的常考点1：变成否定There be句型的否定式的构成和含有be动词的其它句型一样，在be后加上not即可。

例如：例1：There are some pictures on the wall.=There arent any pictures on the wall.例2：There is a bike behind the tree.= There isnt a bike behind the tree.2：变成一般疑问句There be句型的一般疑问句变化是把be动词调整到句首，再在句尾加上问号即可。

但同时要注意：当肯定句中有some 时，要将其改为any（否定变化也一样）。

some 用于肯定句，any用于否定或疑问句。

There is some water on Mars. → Is there any water on Mars?There are some fish in the water. →Are there any fish in the water?3：特殊疑问句对主语提问：当主语是人的时候，则用who 引导，当主语是物的时候，则用what 引导。

注意：无论原句的主语是单数还是复数，对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。

如：There are many things over there. →Whats over there?There is a little girl in the room.→Who is in the room?对地点状语提问：则用where 引导。

如：There is a computer on the desk. → Where is the computer?There are four children on the playground. →Where are the four children?对数量提问：般有两种句型结构：How many+复数名词+are there+介词短语？How much+不可数名词+is there+介词短语？二、Have / has1、定义：指的是主观上的“拥有；持有”，表示某人拥有某物，是一种所属关系2、结构：主语+ have（第三人称单数用has）+ 物品例如：I have some apples.My mother’s has some friends.3、have/has跟主语的搭配第一人称：我，我们I, we第二人称：你，你们you第三人称：除第一、第二人称之外的其他人称第三人称单数：he, she, it, Kitty, Alice, Benhave(第三人称单数)——has语法练习：一）、用“have, has” or “there is , there are”填空1.
