四年级英语 教科版 Unit 1 What

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. ”，也可以直接回答物品名称。 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.

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. I ______ a boy. ______ you a boy? No, I _____ not.

2. The girl______ Jack's sister.

3. The dog _______ tall and fat.

4.The jeans ______ on the desk.

(一）、有be 动词的肯定句和否定句

I am from London. I am not from London.

He is a teacher. He is not a teacher.

She is in the dining room. She is not in the dining room.

My hair is long. My hair is not long.

Her eyes are small. Her eyes are not small.

归纳：在有be 动词的句子中，改否定句时只要在be 动词______加上_____。

（二）、有be 动词的一般疑问句

Am I a Chinese? Yes, you are. No, you aren‟t.

Are they American? Yes, they are. No, they aren‟t.

Is the cat fat? Yes, it is. No, it isn‟t.

6. Whose dress ______ this?

7. Whose socks ______ they?

8. That ______ my red skirt.

9. Who ______ I?

10. Here ______ a scarf for you.

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：

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

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 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. →What's 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 / 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
