I'll take it./I'll take them.3.Here you are.4.buy sb.sth.=buy sth.for sb. 给某人买某物buy sth. from... 从...购买某物5.sell sb.sth.=sell sth.to sb. 把某物卖给某人6.at a great sale相当于on sale，意为“减价出售”。
7.辨析for sale与on salefor sale 表示“待售；供出售”on sale 表示“出售、减价出售”8. 介词for用来表示物品的价格：价格+for+具体物品;Eg：30 dollars for shirt.9.at very good prices 以很优惠的价格at a low/high price 以低价/高价10.the price of ...的价格；the price of+其它；作主语时,谓语动词用单数；Eg：The price of this car is very high.11.expensive/cheap/high/low的区别1)expensive 描述物品贵；2)cheap 描述物品便宜；3)high 表示价格高；4)low 表示价格低；12.hundred,thousand,million(百万),billion(亿)等词，与具体数字连用时，用单数形式，其后不加s和of；当前面没有具体数字时,s和of都加上；Eg: three hundred men teachersEg: hundreds of women teachers13.辨析：clothes与clothingclothes指衣服、服装，作主语时，谓语动词用复数；clothing 指衣服，尤其是某种类型的服装，不可数，作主语时，谓语动词用单数；clothes 指衣服、服装，作主语时，谓语动词用复数；不能直接与数词连；但可以用these/those/some等词语修饰，表示一套衣服用“a suit of clothes”，谓语动词的单复数由suit的单复数决定；拓展：和a suit of 用法相同的还有：a set of；a pair of；14.表示货币等度量单位作主语时，谓语动词用单数；Eg:100 dollars is quite a lot of for him.15.trousers,socks,shorts,shoes等物品常常成双成对出现，它们作主语时，谓语动词常用复数形式。

Unit 7 How much are these socks?
Section A
1.sock 短袜
sock/sɔk/ n.短袜eg:Does she like these socks?她喜欢这双短袜吗?
What color are your socks?你的短袜是什么颜色的?
2.shorts/ʃɔ: ts/ n.短裤eg:Are these your shorts?这是你的短裤吗?
3.trousers/‘trauzə(r)z/ n.(pl.)裤子eg:His trousers are green.他的裤子是绿色的。
How much are those trousers?那条裤子多少钱?
归纳：trousers只用复数形式,表述复数意义,作主语时,谓语动词用复数形式。
shorts(短裤),pa nts(裤子),jeans(牛仔裤),clothes(衣服)与其类似。
【注意】表示pants,shorts,trousers等的数量时,常用pair,a pair of可表示“一条……”。
(易错点)
4.shoe/ʃu:/ n.鞋eg:Where are my shoes?我的鞋子在哪儿?
Her shoes are $18.她的鞋18美元。
【注意】shoe常用复数。
5.SALE 出售,特价销售
sale/seil/n.出售,特价销售eg:What is on sale? 什么正在特价销售?
Some skirts,socks,shorts,pants and shirts are on sale.一些裙子、短袜、短裤、裤子和衬衫正在出售。
拓展：on sale表示“出售,特价销售”,可以用于be动词之后作表语,也可用于名词之后作定语。
注意sell为动词,表示“卖;出售”的含义。
被出售的物品通常是用作sell的宾语,而用作be on sale的主语。
eg:Some new cars are on sale.一些新车在出售。
The store sells different new cars.这家商店出售各种新车。
6.—How much is this T-shirt? 这件T恤衫多少钱?
—It‘s seven dollars.七美元。
使用语境：适用于询问单个物品的价格,答语用“It’s...”。
how much 多少钱
拓展：how much 意思为“多少钱”,询问某物的价格;how much 还有一个意思为“多少”,询问某物的数量。
辨析：how much 与how many
how much表示“多少钱”时,用于询问物品的价格;表示“多少”时,用于询问不可数名词的量,其后接不可数名词;how many表示“多少”时,用于询问可数名词的数量,其后接复数名词。
(易混点)
How mu ch are these socks?
也可用作不可数名词eg:Tha nks for something to drink?
—Red.红色的。
want/wɒnt/ v.想要;要eg:What do you want?你想要点什么?
Do you want some milk?你想要一些牛奶吗?
拓展：want表示想要某个物品,也可接动词不定式,表示“想做某事”,即want to do sth.。
eg:Tom wants to buy a green T-shirt.汤姆想买一件绿色的T恤衫。
Do you want to go shopping with me?你想和我去购物吗?
11.How about this one?这件怎么样?
使用语境“How about...?”多用于提出建议或向别人征求意见。
eg:—How about going for a walk?去散步怎么样?
—That‘s a good idea.真是一个好主意。
how about怎么样
拓展how about等同于what about,后跟名词或动词-ing形式作宾语。
eg:How about the book?这本书怎么样?
How about playing basketball with me?和我打篮球怎么样?
A.to take
B.takes
C.taking
12.It looks nice.它看起来很漂亮。
look /lʊk/ v.看;看上去eg:Please look at the picture.请看这幅图画。
The girl in red looks beautiful.那个穿红色衣服的女孩看上去很漂亮。
归纳：look意思为“看”时,是不及物动词。
后面跟宾语时需加介词at。
look意思为“看上去”时,用作系动词,后面跟形容词作表语。
此时,look无进行时态,无被动形式。
辨析look,see,watch与notice
①look意思为“看”,是指想看而投注目光,不管结果如何,表示看的动作。
②see意思为“看见”,指有意或无意地看到,强调看的结果。
③watch意思为“观看”,指特别留意地、感兴趣地看运动着的东西。
④notice意思为“注意到”,指偶尔看到细小但可能是重要的事情。
eg:The boy looks hard but can see nothing.这个男孩努力地看,却什么也没看到。
My father is watchi ng TV.我的爸爸正在看电视。
Do you notice anything different?你注意到什么不同的事情了吗?
13.I‘ll take it.我买了。
使用语境：当你选定商品,决定要买时,就可以说“I‘ll take it/them.”,而不说“I‘ll buy it/them.”。
这里的it/them指代的是上文提到的商品。
eg:—How much is the jacket?这件夹克衫多少钱?
—Forty dollars.四十美元。
—Oh,it‘s cheap.I‘ll take it.哦,很便宜。
我买了。
14.Two dollars for one pair and three dollars for two pairs.一双两美元,两双三美元。
pair/peə(r)/ n.一双,一对eg:I want a pair of trousers.我想买一条裤子。
This pair of socks is five dollars.这双短袜五美元。
拓展pair常用来表示成对出现的物品的数量,表示“一对,一双,一副,一把,一条”之意。
pair短语作主语时,谓语动词的人称和数要与pair保持一致。
eg:A pair of glasses is ten dollars.一副眼镜十美元。
15.Here you are.给你。
使用语境：这是英语中的一句常用口语,它的基本意思是“给你。
”、“你所要的东西在这儿。
”。
它在不同的场合,可以有不同的意思。
—I want a pair of socks.我想买一双短袜。
—Here you are.给你。
16.Thank you.谢谢你。
使用语境：“Thank you.”是得到了别人的帮助后而表示谢意的交际用语。
拓展:向别人表示感谢时除了用“Thank you.谢谢你。
”,还可用“Thanks a lot.多谢。
”,“Thank you very much.非常感谢你。
”,“Many thanks.多谢。
”等。
17.You’re welcome.不用客气。
使用语境：用于不同的语境,含义不同,可以表达“不用谢。
”、“你是受欢迎的。
”等含义。
welcome /’welkəm / adj.受欢迎的;可随意的
eg: —Thank you very much.非常感谢你。
—You‘re welcome.不用谢。
/不客气。
—Can I come over and visit you ? 我能顺便来拜访你吗?
—Ye s,you‘re always welcome.可以,随时欢迎你来。
