how much用于提问某物的价格，意为“多少钱”，其句式为“How much + be +主语?”
当主语是不可数名词或可数名词单数时，be动词用is，答语为It’s+数额；当主语是可数名词复数时，be动词用are，答语为They’re+数额。如：
—How much is this bag? 这个包多少钱?
—It’s six dollars. 六美元。
—How much are the apples? 这些苹果多少钱?
—They’re two dollars a kilo. 两美元一千克。
2. socks是sock的复数形式。在英语中，成双成对的物品常以复数形式出现。 例如：
shoes shorts trousers glasses chopsticks scissors
此类词作主语时，谓语动词用复数形式；但与a pair of …（一双、一对或一副）连用作主语时，谓语动词用单数形式。如：
My shoes are under the bed. 我的鞋在床下了。
That pair of shorts is Jack’s. 那条短裤子是杰克的。
3. Can I help you? 我能帮助您吗？
这是商店售货员或其他服务人员招呼顾客时的礼貌用语，相当于What can I do for you?。接受对方的帮助常回答“Yes, please.”；拒绝对方的帮助用“No, thanks.”作答。如：
—Can I help you? 我能帮助您吗？
—Yes, please. I want a pen. 是的。
我想要一支钢笔。
4. I need a sweater for school.
我需要一件毛衣上学穿。
need是实义动词，意为“需要”。常用于以下句式中：
1) need+sth.，表示“需要某物”。如：
I need some erasers. 我需要一些橡皮。
2) need +to do sth. 表示“需要做某事”，这时need的主语是“人”。如：
You need to put on your jacket.
你需要穿上我有夹克。
5. I’ll take it. 我要买下它。
此句是选好商品并决定购买时的常用语。若选定的物品是单数，可以说“I’ll take/have it”；若选定的物品是复数则应说“I’ll take/have them.”。如：
The sweater is cheap. I’ll take it.
这件毛衣很便宜。我买了。
—The oranges are 2 dollars. 这些桔子两美元。
—I’ll take them. 我买了。
Can I help you ?
服务员首先打招呼 May I help you?
What can I do for you?
I’m looking for …
顾客讲出要求 需要购买时 I’d like …
I want …
Can I have a look at…
只是闲逛时 Just have a look.
No, thanks. I’m just looking around.
询问顾客想买的商品时 What kind/color/size do you want?
