3、点句型1.I have a big nose = My nose is big. I have big eyes. = My eyes are big. She has a big nose. = Her nose is big. She has big eyes. = Her eyes are big. 2. Whos that boy?那个男孩是谁？这是由Who引导的特殊疑问句，询问某人的身份。如：Whos that girl over there?Whos 是Who is 的缩写形式。名词和代词和am ,is ,are ,have ,has 的连词都可以使用缩写形式。助动词和情态动词的否

4、定形式也可以缩写。如：Who is =Whos Who are =Whore What is =Whats What are = WhatreThat is =Thats can not=cant do not =dont does not =doesntTom is =Toms they are =theyre3. Where is he from? 他来自哪里？ 此句是where引导的特殊疑问句，旨在询问别人的家乡在哪里或对方的出生地。 询问“（某人）是哪里人”，常用 Where from? 结构。be from相当于come from ，因此上句可改为：Where does he com

5、e from?4. Thats right. 是的，你说的对。 Thats right 是对某一观点、判断或回答作评判的用语，或对对方的说法表示赞同，常用Thats right, 表示“是的，对了，你说的对”等意思。有时也可以用Youre right 或Right, OK来代替。如： Are you in Class One? 你在一班吗？ Thats right. 是的/ 没错。5. Im thirteen years old. = Im at the age of thirteen. 我13岁了。6.Please give this letter to Maria. She is in C

6、lass Four, Grade Seven. 请把这封信给玛丽亚，她在七年级四班。（1）give 动词， “给”。give sth. to sb. “把某物给某人”相当于give sb. sth. 。如：Please give this knife to Zhang Hua. Please give Zhang Hua this knife. (2) Class Four, Grade Seven “七年级四班”， 英语中一般先说小的地方，后说大的地方。这就是英语和汉语语序的区别。7. Sorry, I dont know her. 对不起，我不认识她。(1)Im sorry是英语中最常用的

7、交际礼貌用语之一，意为“对不起”，口语中也可直接用Sorry。(2) I dont know her.我不认识她。其中， know 有两种意思， 一是“知道”，二是“认识”。在此句中，就是第二个意思。如：I dont know how to do this work. 我不知道如何去做这项工作。 Do you know this man? 你认识这个人吗？8. What does she look like? 她长什么样子？ 这是用来询问人的外貌的句型,可根据人的外貌特征直接进行回答。如：What does he look like? He has a round face and big e

8、yes. 句中look like “看起来像”，look为连系动词, 意为“看起来”,“看上去”,like 为介词,意为“像” 如:I look like my mother. 辨析： look like / be like（1）look like“看起来像”“看上去像”， 指“外观像”。（2）be like“像一样”，指“品质、性格。”如：What does he look like? 他长什么样子？ What is he like? 他是一个什么样的人？三、重点语法have/has 的用法。动词have作为有使用时，表示某人(物)有用于第一、二人称单数I、you和复数主语，其单数第三人称形

9、式为has，用于第三人称单数he、she、it和单数主语。肯定句：主语have / has宾语。例如：1. I have an English book. 2. Lily has a dog. 3. They have many friends.否定句:在have、has后直接加not。主语have not / has not+宾语。例如：1. You have not a red car. 2. She has not a new bike. 3. Lily and lucy have not a big family.一般疑问句: 在英语中，要借助于助动词变为问句和否定句，但has要变为h

10、ave。在作回答时也要用do或does的形式。否定句中，用主语dont / doesnt+have+宾语。例如：1. I dont have an English book. 2. She doesnt have a new bike.一般疑问句中，用Do / Does+主语have+宾语。例如：1. Do you have an English book? Yes, I do. (No, I dont.)2. Does she have any friends? Yes, she does. (No, they doesnt.)特殊疑问句中，用特殊疑问词do/ does+主语+have+其它

11、。例如：1. What do they have? 2.

14、n blue pants is peter.定冠词the 的用法 I have a pen. The pen is red.六、重点讲解1.We both have black hair and black eyes.我俩都长着黑头发、黑眼睛。both pron（与复数名词连用）意为“两个，两个都”。Both 放在be 动词，助动词或情态动词后面，实义动词的前面。如：We are both from Sichuan.我俩都来自四川。They both work in Toronto. 他俩都在多伦多市工作。2 But you look the same. 但是你们看起来一样。 We dont

15、have the same looks, but we are good friends! 我们没有相同的外貌，但我们是好朋友！以上两句中出现了look the same 与 the same looks 两个短语。虽然是由三个同样的单词组成的两个短语，但是由于它们的位置不同，意思就不一样。look the same中的 look 是动词，意思是“看起来.”，而the same looks 中的look 为名词，常用复数，意思是外表，外貌，样子”。因此 look the same 意为“看起来很像”，而 the same looks意为 “相似的外貌”【链接】look at 看.； look

16、like看起来像。如：Please look at the blackboard.请看黑板。He looks like his father.他看起来像他的爸爸。【拓展】look the same 的反义词组是：look different.3.Please give this letter to Maria.请把这封信给玛丽亚。give 给 give sth to sb 或give sb sth把某物给某人。因此，此句也可改为：Please give Maria this letter.但是当用代词It（它）， them(他们)代替某物时，只能用于give it/them to sb结构中。

17、如：Please give it to him.请把它给他。4. What does she look like? 意为某人看上去是怎么样？该句常用来表示对某人相貌、身材等的提问。如：-What does your sister look like? 你姐姐看起来怎么样？-She is tall and thin她又瘦又高。-What do your parents look like? 你的父母看起来什么样？My mother is short but my father is tall.我的妈妈矮，但是我的爸爸高。（2） look like.意为看上去像”,like 为介词，意为“像.一样
