Unit 7  Grammar and Writing

单元语法专讲：一、how much 引导的疑问句

知识点01  how much询问价格

用法how much常用于询问某物的价格，其结构为“How much+be动词＋主语？”。当主语是可数名词单数或不可数名词时，be动词用is,答语为：“It's...”；当主语是可数名词复数或不仅仅是一种东西时，be动词用are,答语为：“They're...”上述两种情况都可直接回答钱数。

－How much is the salad?沙拉多少钱？

－It's five yuan./Five yuan.五元。

－How much are the apples?这些苹果多少钱？

－They're eight yuan./Eight yuan.八元。

【即学即练1】

－                is the schoolbag?

－60 yuan.

A.How often             B.How old             C.How much

解析：

由答语可知是询问书包的价格，应用how much提问。

知识点02 询问价钱的同义句

用法 询问商品价格时，还可以用“What's the price of..?”句型，意为“。·····的价格是多少？”；无论被询问的物品是不可数名词还是可数名词的单数或复数，be动词都用is,不能用are.其答语为：“It's...（价格是）······”这是由price决定的，用心哦！

－What's the price of the book?这本书的价格是多少？

－It's five yuan.5元。

－What's the price of these eggs?这些鸡蛋多少钱？

－It's ten yuan.10元。

知识点03【高频】辨析 how much 与how many

how much后接不可数名词,对不可数名词数量提问。单独使用，后不接名词提问物品价格。

how many后接可数名词复数,对可数名词数量提问。

How much meat do you want?你想要多少肉？

－How much are the pencils?这些铅笔多少钱？

－They are forty yuan.它们40元。

How many pears do you want?你想要多少梨？

－How many people are there in your family?你家有几口人？

－There are five(people).有五口人。

How much用法

1.“多少”，用来询问事物的数量，后接不可数名词。

How much bread is there on the table?桌子上有多少面包？

2.“多少钱”，可单独使用，用来询问某物的价格。

How much is your new computer?你的新电脑多少钱？

【即学即练2】

－                        Disneyland parks are there in China?

－Two.

A.How many         B.How often          C.How soon          D.How long

解析：

根据答语“Two.”可知是询问可数名词的数量，应当用how many提问。

单元语法专讲：二、基数词

知识点04定义

表示事物数量多少的数词叫作基数词，如one,two,three等。

知识点05基数词的拼写

（1)one-twelve,无规律可言，应当逐一记忆。

（2)thirteen-nineteen,表示“十几”，在个位数后加后缀－teen,读作／ti:n/,但要注意下面几个词的拼写：thirteen(13),fifteen(15),eighteen(18).

（3)twenty到ninety,表示“几十”，以－ty结尾，但需注意下面几个词的拼写：

twenty(20),thirty(30),forty(40),fifty(50),eighty(80).

（4)“几十几”的表达方法：用整十数加个位数表示，中间用连字符“－”把整十数和个位数连接起来。如：

twenty-five(25),sixty-eight(68).

（5）一百的表达方式为one hundred或a hundred.要表示“几百”，用具体数字加上hundred,如five hundred(500),

意此时的hundred是单数形式。表示“几百几”时，要在百位数和十位数（或个位数）之间加and.如：one hundred

and two(102).

数词记忆规则歌诀：

基数词词不难记，找出规律很容易：

一至十二形各异，加上－teen为十几，

thirteen.fifteen看仔细eighteen 只有一个t;

twenty却是很奇怪，forty 本身也不乖，

eighty一起搞例外，跟着也把规则坏；

十位后面是个位，表示数字“几十几”，

表示“几百几十几”，and常把百、十系。

勤学妙记加练习，hundred就是你的好成绩。

知识点06基数词的用法

1.用法

表示数量，置于名词之前。She has two brothers.她有两个弟弟。

表示编号，置于名词之后。They are in Class Five.他们在五班。

表示号码。His phone number is 337-5683.他的电话号码是337-5683.

表示时间。It's 10:00 now.现在是10点。

表示年龄。My sister is 8 years old.我妹妹8岁了。

用于计算。Two and four is six.2加4等于6.

2.基数词只能修饰可数名词，要注意基数词和名词在数上要保持一致。

one banana一根香蕉   five boys五个男孩

3【难点】hundred,thousand,million等与具体数字连用时，用单数形式，且后不接介词of;当其前面没有具体数字时，要用复数形式，且后面要加of.－s和字母f相伴出没！

three hundred teachers 三百位老师

hundreds of students 数百名学生

【即学即练3】

Today is Jack's birthday.He is               years old now.

A.fourteenth             B.fourteen            C.the fourteenth           D.the fourteen

解析：

句意为“今天是杰克的生日。他现在14岁了”。表示年龄用基数词，而且前面不加定冠词。

【即学即练4】

-Where were you born,Michael?

－I was born in a small village with only three             people.

A.hundred           B.hundreds          C.hundreds of

答案 A

【即学即练5】

There are               students in our school.

A.hundreds            B.hundreds of          C.hundred of

解析：

hundred前面没有具体数字时，要用复数形式，且后面要加of.答案B
