Unit 1 What’s in your room 1、 词汇 Want / next to.../ between 2、 重点句型 1〕询问某物里面有什么的句型----What’s in... 句型结构：What’s in + 其他？ 重点解析：此句型是由what引导的特殊疑问句。疑问词what意为“什么〞，几次in 意为“在...里面〞。答语为“There is/are + + in + 其他.〞，也可以直接答复 物品名称。 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〞。 〔强调两者互相接触〕例如：I put my pen on the desk. In表示“在...里面〞 例如：The ball is in the box. Near表示“在...附近〞 例如：He lives near the river. Over表示“在...上面〞. (不与物体接触〕例如：There is a bridge over the river. Under表示“在...下面〞 例如：There is a pair of shoes under the bed. Above表示“在...上面〞 例如：The picture is above the bed. Behind表示“在...后面〞 例如：There is a river behind the house. In front of表示“在...前面〞 例如：There is a big tree in front of the house. Next to...在旁边 例如：There is a bed next to the window. Between 在〔两者〕之间 例如：There is a chair between the door and the window. 4、 语法：be动词的用法和区别 there be句型和have/has的用法区别 一、 Be动词 Be动词：am、 is、 are 口诀：我用am, 你用are, is用在他她它，复数全用are。 例题： 1.

All the students were very excited. w W w . 否认句：________________________________________________ 一般疑问句：____________________________________________ 肯、否认答复：__________________________________________ 二、 There be (一) ：there be 句型根本认识 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. 本卷须知：  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： ① There is a bird in the tree.   树上有一只鸟。w W w .     ② There is a teacher and many students in our classroom.  我们教室里有一位老师和许多学生。      ③ There 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：变成否认 There be句型的否认式的构成和含有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 aren't any pictures on the wall. 例2：There is a bike behind the tree. = There isn't 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〔否认变化也一样〕。 some 用于肯定句， any用于否认或疑问句。 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，那么用who 引导，当主语是物的时候，那么用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(答复时却要根据实际情况来决定)。如： There are many things over there. →What's over there There is a little girl in the room.→Who is in the room 对地点状语提问：那么用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 / has 1、 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, Ben have(第三人称单数)——has 语法练习： 一） 、用“have, has〞 or “there is , there are〞填空 1. I________a good father and a good mother. 2. ____________a telescope on the desk. 3. He_________a tape-recorder. 4. _____________
