1、 七年級(jí)上英語(yǔ)講義Unit 7 How much are these socks?學(xué)生姓名 就讀學(xué)校 時(shí) 間 本章的知識(shí)清單知識(shí)框架表知識(shí)點(diǎn)重要性級(jí)別U 1重點(diǎn)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(yǔ)法How much的用法基數(shù)詞短語(yǔ)集萃161.how much 多少錢(qián)2.look

2、 nice 看起來(lái)很好3.a pair of 一條；一雙；一副4. clothes store 服裝店5. on sale 廉價(jià)出售6.at a price 以的價(jià)格7. come and buy 來(lái)買(mǎi)8. for only $22 僅售22美元9. $2 for three pairs 兩美元三雙10. come to 來(lái)單元語(yǔ)法一、how much的用法how much的意思是“多少”，常用來(lái)引導(dǎo)特殊疑問(wèn)句，用于詢問(wèn)價(jià)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(dāng)于“Whats the price of+名詞？”，

3、意為“多少錢(qián)？”。在回答這個(gè)問(wèn)句時(shí)，若所詢問(wèn)的東西是不可數(shù)名詞或可數(shù)名詞單數(shù)，謂語(yǔ)動(dòng)詞用is；若所詢問(wèn)的東西是可數(shù)名詞復(fù)數(shù)或不止一種，謂語(yǔ)動(dòng)詞用are。常用“Its/Theyre+價(jià)格.”這個(gè)句型回答。How much is your sweater? 你的毛衣多少錢(qián)？ 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(qián)？How much are the socks? 這些短襪多少錢(qián)？ Theyre $20. 它們20美元。拓展：how much除詢問(wèn)價(jià)格外，還可以詢問(wèn)數(shù)量，意為“多少

4、”。但它一般只詢問(wèn)不可數(shù)名詞的數(shù)量，且被詢問(wèn)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(wèn)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(dú)立的單詞，要逐個(gè)熟記，如zero, one, two, three, four, five, six, seven, eight, nine, ten,eleven, twelve。（2）1319均是由在個(gè)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(gè)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(gè)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(gè)一個(gè)單獨(dú)記。后加teen變十幾，thirteen，fifteen看仔細(xì)。十八需要看準(zhǔn)確，eighteen只有一個(gè)t。二十到九十加ty，twenty，eighty重點(diǎn)記。forty去掉字母u，thirty，fifty重點(diǎn)記。十位數(shù)后接個(gè)位數(shù)，表示數(shù)字幾十幾。排列順序不費(fèi)力，連字符號(hào)莫丟棄。寫(xiě)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(jī)。2.基數(shù)詞的用法（1）表示數(shù)量、年齡等，在句中可作主語(yǔ)、定語(yǔ)或表語(yǔ)。Three will be enough. 三個(gè)就夠了。There are two cups on the table. 桌上有兩個(gè)杯子。Im twelve years old. 我12歲了。（2）表示編號(hào)，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(hào)碼，按單個(gè)基數(shù)詞讀出。 698-7245讀作：six nine eight seven two four five（4）表示時(shí)刻 8:
