Unit 7 How much are these socks?知识点复习

1.How much is it?它多少钱?

①对价格提问,用how much.不用how much money. How much 后面的be动词随着主语的变化而变化。如:How much are these socks?

②How much is it? = What’s the price of it?注意回答的不同。如,How much are these socks?回答:                What’s the price of these socks?回答:

联想:The price of these socks ___ 5 dollars.

2.Can I help you?我能为你服务吗?

①这是在商店里购物常用的一句话。肯定回答:Yes, please.否定回答:No, thanks/thank you.

②Can I help you? = What can I do for you? 注意两者回答的不同。

3.I need a sweater for school.我需要一件毛衣上学穿。

①need…for… 固定搭配,需要…来…,其中for表目的,如I need some color pencils for this afternoon’s art class.注意这里的介词用for而不是to。又如:I need a sports bag= I need a bag for sports. I need a pair of black shoes for school.

②need的用法见重点单词解析。

4.What color do you want?你想要什么颜色?

对颜色提问,一律用what color,不用what colors.如:What color do you like? I like green and blue.(注意千万不要把blue写成bule)

5.It looks nice.它看起来很漂亮。

looks此处是系动词,看起来。后面接形容词做表语。如This pair of shoes looks great.

与look有关的短语:

look like看起来像。他看起来像他的爸爸。

look the same 看起来一样     look for 寻找    look after 照顾 照看

6.I will take it.我要买下来。

购物常用语。

①take 翻译成买下来。此处不用buy,因为buy是买。句型是buy sb sth. = buy sth. for sb.为某人买某物。请举例。

从某处买某物 buy sth. from sp 例句:他在酷先生服装店里买了一些衣服。

②it指代上文中的单身。如果是复数,记得要用them。

7.Two dollars for one pair and three dollars for two pairs.一双两美元两双三美元。

①此处for表示价格,用法是 价格+for+具体物品

②for的另一种用法是用在价格前,表示交换。如We have yellow sweaters for only 25 yuan.

8.Come and buy your clothes at our great sale.来买衣服吧! 我们在大甩卖.

① and此处表目的。Come的目的是来buy your clothes.

② clothes衣服,没有单数形式。不能用one two three 等具体数词修饰,但可用these some 等修饰。

at our great sale,在我们大甩卖的时候。

9.We sell all our clothes at very good prices.我们以非常好的价格出售我们所有的衣服。

①sell是动词,出售。而sale是名词,两者要区分清楚。sell sb sth.= sell sth. to sb.②all our clothes 我们所有的衣服,all 和 our都修饰名词clothes。注意,all与其他限定词连用,一起修饰名词时,放在最前面,又叫排头兵。如:all the students  all her clothes  all these rooms

③以…的价格,用介词at。at very good / high / low prices 以非常好/高/低的价格

具体的价格前可用for 如,We sell all our clothes for 10 yuan each.

10.For boys, we have black trousers for only $22.对于男孩们,我们有黑色的裤子仅售22美元。

①for 对于。For boys,对于男孩们。

②for 用在价格前表示交换,此处不能用are。比较:The black trousers are only $22.

11.For girls, we have skirts in purple for only $20.对于女孩们,我们有紫色的裙子仅售20美元。

skirts in purple,紫色的裙子。in purple,颜色前面用介词in,介词短语作定语用在所修饰词的后面。We have skirts in purple =We have purple skirts.但不能说成 We have in purple skirts.

12.Come to Mr. Cool’s Clothes Store now.现在就来酷先生服装店。

① come 来,来到。。。,用come to,如come to my home  come to school

② Mr. Cool’s Clothes Store 是专有名词,所以每个单词的开头字母都得大写。有名字的店铺前不加the。

13.How about these purple ones.这些紫色的怎么样?

这些紫色的,是复数形式,所以不能用one。需要在它的后面加复数。
