WhatcanIdoforyou?MayIhelpyou?IsthereanythingIcandoforyou?语法重点二：I'lltakeit.我买了。1.此句是选好商品并决定购买时的常用语。2.句中的I'll是Iwill的缩写形式，will是助动词，意思是“将要”，用来表示将来发生的动作。3.句子中的take意思是“买”，相当于buy。另外，I'llhaveit也可以表示同样的意思。3aMakesentencesinthechartwiththewordsinthethreeboxes.Howmuchis...thethisthatyellowpurplebrownwhitegreenblueredblackT-shirt.sweater.hat.skirt.jacket.bag.Howmuchare...thethosethesetrousers.shorts.socks.shoes.Lookatthepicturesandwritethequestionsandanswers.1.Howmuchisthehat?____________________2.Howmuchisthebag?____________________3.HowmuchistheT-shirt?________________4.___________________________They'rethreedollars.5._____________________________It'sninedollars.6.____________________________It'seightdollars.3bIt'sfivedollars.It'stendollars.It'ssixdollars.Howmucharethesocks?Howmuchisthesweater?Howmuchistheskirt?语法重点三：Howmuch...意为“......多少钱”，根据主语的单复数有两种句型：(1)---Howmuchis+单数主语+?---Itis+钱数.(2)---Howmuchare+复数主语+？---Theyare+钱数.

对价格进行询问时，还可用：What’sthepriceof...?使用这一句式时，无论被询问的商品是单数还是复数，be动词都用is，不能用are；其答语为：It's...“价格是......”。如：---What'sthepriceofthesebooks?---It'stenyuan.辨析howmany与howmuch

howmany和howmuch都可对数量词提问，表示“多少”。howmany后接可数名词复数，而howmuch后接不可数名词，即howmany用于提问可数名词的数量，而howmuch用于提问不可数名词的数量。如：Howmanyapplesdoyouhave?

Howmuchorangedoyouwant?语法重点三：They'rethreedollars.它们3美元。1.表示“美元”的dollar可使用单数和复数形式，但表示“人民币”的yuan不能用复数形式。如：fivedollar五美元符号：＄5.00fiveyuan五元符号：￥5.002.此句中They’re是Theyare的缩写形式。要注意简略答语中的Yes,itis.不可缩写为Yes,it’s.。当句子以theyare结尾时，也不可以缩写为they're。语法重点四：Howmucharethesocks?袜子多少钱？1.表示服装类的名词trousers,shorts,shoes,socks等常用复数形式。如果要表示数量，可使用量词apairof的相应形式来表述。如：apairofshoes一双鞋twopairsofsocks两双袜子threepairsofshorts三条短裤2.当它们和apairof连用作主语时，谓语动词要根据pair的数来变化。如：ThatpairofpantsisTom's.语法重点五：3c.StudentA,lookatthepicturesin3bforaminuteandthencloseyourbook.StudentB,askquestions.Howmucharethesocks?Umm,they'rethreedollars.小结训练用划线词的反义词或对应词填空。1.Ilike______hair.Idon'tlike_____hair.2.Thejacketistoo______forme.Givemea______one,please.3.Myschoolbagis______,butmyT-shirtis______.4.Ithinkthisbookisvery______andthatbookisvery________.5.Gina'ssweaterisinthe______and______case.shortlongbigsmallblackwhiteeasydifficultlostfound小结训练句型转换。1.ThewhiteT-shirtis15dollars.（对划线部分提问）___________isthewhiteT-shirt?2.Thathatisblack.（改为同义句）Thatis__________hat.3.Theyellowshoesare40yuan.（改为否定句）Theyel
