人教新目标英语：七年级上册unit3知识点总结

Unit3 Is this your pencil? 知识点复习

重点句子解析

1.Is that your schoolbag? 那是你的书包吗？在英语中，Is this / that…?

句型，肯定形式用Yes, it is.(不能缩写)否定形式用No, it isn’t.同样地，他们的复数形式：Are these/those…?回答，也只能用：Yes, they are. (不能缩写)No, they aren’t.

2.Are these your penc ils? No, they are Bob’s.这些是你的铅笔吗？不，

他们是鲍勃的。Bob’s是名词所有格。表示二者之间的所属关系。

其构成：

①一般情况下，在单数名词的词尾直接加“‘s”构成所有格。例如：

Li Ming’s football李明的足球；Kate’s cat凯特的猫

②以-s结尾的复数名词，在词尾直接加“‘”构成所有格。例如：

the teachers’ chairs老师们的椅子；the students’ books学生们的书

③不以-s结尾的复数名词在词尾加“‘s”构成所有格。例如：

Ch ildren’s Day儿童节；

★若表示两个人各自所有的两个东西，则应在两个名词后面分别加上“‘s”，而且后面要接复数名词；若表示两个人共同拥有的一个东西，则只能在后面那个名词后面加上“‘s”，而且后面要接单数名词。试比较：

Tom’s and Mike’s rooms汤姆和迈克的房间

（两人各有一间，共两个房间，不是共同拥有）

Tom and Mike’s room汤姆和迈克的房间（两人共同拥有的一个房间）3.What about this dictionary.这本字典怎么样？What about …?“……怎

么样？”, =How about …?后面可接名词、代词或动词-ing形式。用来询问对方的看法或提建议。如：

The blue jacket is Mike’s. What about the red jacket?

I’m in No.14 Middle School. What about you?

注意：dictionary变复数，改y为i加es，既dictionaries

4.Thank you for your help.谢谢你的帮助。Thank you for = Thanks for 为了。。。而感谢。其中for是介词，后可以接名词、代词，或动名词。这个句子中，help是不可数名词。这个句子还可以换成Thank you for

helping me.

5.Ask the teacher for it.向老师要它。ask sb. for sth. 向某人索要某物。例如，Ask the teacher for help. Ask my parents for money.联想：寻求帮助——

要钱——

关于ask的其它用法，见重点单词解析。

6.Some keys are in Classroom 7E.一些钥匙在7E教室里。

①Some既可以修饰可数名词复数也可以修饰不可数名词。

②通常来说，some用语肯定句，any用于否定和疑问句。但在表示请求的疑问句中用some。

③some keys做主语谓语动词用复数，A set of keys 做主语谓语动词用单数。联想：The price of the shorts ____ high.

④在教室里固定搭配in the classroom.但是，表示单位数量的名词提前，前不用冠词，且每个字母都要大写。In Classroom 7E. Unit One Lesson Two

⑤这个句子如果用there be 句型来做就是：

7.I lost my school ID card.我丢了我的学生证。Lost是lose的过去式。

school ID card学生证ID card 身份证。一张身份证----

你的身份证号码是多少？：

8. I must find it.我必须找到它。Must 是情态动词，必须。没有人称和数的变化。与can一样，后街动词原形。Find找到。它的过去式是found。区分：find与look for。

9.Call me at 685-6034。打电话685-6034给我。固定搭配：call sb. at 号码
