1、 七年級上英語講義Unit 7 How much are these socks?學(xué)生姓名 就讀學(xué)校 時 間 本章的知識清單知識框架表知識點重要性級別U 1重點句型-How much are these socks?-Theyre two dollars.-Can I help you?-Yes, please.Here you are.Come and buy your clothes at our great sale!We sell all our clothes at very good prices.語法How much的用法基數(shù)詞短語集萃161.how much 多少錢2.look

2、 nice 看起來很好3.a pair of 一條；一雙；一副4. clothes store 服裝店5. on sale 廉價出售6.at a price 以的價格7. come and buy 來買8. for only $22 僅售22美元9. $2 for three pairs 兩美元三雙10. come to 來單元語法一、how much的用法how much的意思是“多少”，常用來引導(dǎo)特殊疑問句，用于詢問價格。常用結(jié)構(gòu)有：“How much is+可數(shù)名詞單數(shù)或不可數(shù)名詞？”或“How much are+可數(shù)名詞復(fù)數(shù)？”，相當于“Whats the price of+名詞？”，

3、意為“多少錢？”。在回答這個問句時，若所詢問的東西是不可數(shù)名詞或可數(shù)名詞單數(shù)，謂語動詞用is；若所詢問的東西是可數(shù)名詞復(fù)數(shù)或不止一種，謂語動詞用are。常用“Its/Theyre+價格.”這個句型回答。How much is your sweater? 你的毛衣多少錢？ Its 50 dollars. 它50美元。How much is the coat?=Whats the price of the coat? 這件外套多少錢？How much are the socks? 這些短襪多少錢？ Theyre $20. 它們20美元。拓展：how much除詢問價格外，還可以詢問數(shù)量，意為“多少

4、”。但它一般只詢問不可數(shù)名詞的數(shù)量，且被詢問的物品名詞要跟在how much之后。其結(jié)構(gòu)為“How much+不可數(shù)名詞+一般疑問句？”How much water do you want? 你想要多少水？How much bread do you have? 你有多少面包？二、基數(shù)詞1.基數(shù)詞的構(gòu)成（1）基數(shù)詞從0到12是獨立的單詞，要逐個熟記，如zero, one, two, three, four, five, six, seven, eight, nine, ten,eleven, twelve。（2）1319均是由在個位數(shù)后加-teen構(gòu)成（13、15和18除外），如thirteen

5、, fourteen, fifteen, sixteen, seventeen,eighteen, nineteen。（3）2090中表示整十的數(shù)字，以-ty結(jié)尾。注意：twenty（二十），thirty（三十），forty（四十），fifty（五十），eighty（八十）。（4）2199等表示“幾十幾”的基數(shù)詞，由十位數(shù)和個位數(shù)之間加連字符“-”構(gòu)成。21twenty-one 32thirty-two 43forty-three 54fifty-four65sixty-five 77seventy-seven 88eighty-eight 99ninety-nine（5）101999等表示“

6、幾百幾”的基數(shù)詞，在百位數(shù)hundred之后加and，再加十位數(shù)和個位數(shù)。101one hundred and one 365three hundred and sixty-five 999nine hundred and ninety-nine助記：基數(shù)詞不難記，找出規(guī)律很容易。零至十二樣各異，一個一個單獨記。后加teen變十幾，thirteen，fifteen看仔細。十八需要看準確，eighteen只有一個t。二十到九十加ty，twenty，eighty重點記。forty去掉字母u，thirty，fifty重點記。十位數(shù)后接個位數(shù)，表示數(shù)字幾十幾。排列順序不費力，連字符號莫丟棄。寫到幾百幾

7、十幾，中間and莫忘記。巧學(xué)妙記加努力，hundred是你的好成績。2.基數(shù)詞的用法（1）表示數(shù)量、年齡等，在句中可作主語、定語或表語。Three will be enough. 三個就夠了。There are two cups on the table. 桌上有兩個杯子。Im twelve years old. 我12歲了。（2）表示編號，用“事物+基數(shù)詞”表示。Lesson One 第1課 Unit Two 第2單元 Room 101 101房間（3）表示號碼，按單個基數(shù)詞讀出。 698-7245讀作：six nine eight seven two four five（4）表示時刻 8:
