most表示“大部分，多半”的意思。

buy sth. for sb. 意为“给某人买某物”，相当于buy sb. sth. 例如：

2. Can I help you?
“Can I help you? /May I help you?/ What can I d o for you? / Is there anything I can do for you?”是商店售货员在招呼顾客的时候经常用的交际用语，用来很礼貌的招呼顾客。

不能用“What do you want to buy?或What do you want? ”，这样的句型是中国式的表达。

此时，顾客如果想买东西就会说：
Yes, please. I would like to＋要买的商品。

是的，我想买……
如果顾客不想买商品，就会说：
No, thanks. I just have a look.或No, thanks. I am just looking around.
不，谢谢。

我只是随便看看。

注意：May I help you?在不同的服务场所有不同的意思。

在商店里面，售货员说的时候就是：“你想买什么？”；在图书馆里，管理员说的时候就是：“你想借什么书？”；在饭店里，服务员说的时候就是：“你想吃什么？”；在车站里，售票员说的时候就是：“你买什么样的票？”。

本句中用了need to do sth. 的结构。

need to do sth. 意为“需要做某事”。

例如：
You need to come here early. 你需要早来这里。

【拓展】need后还可以直接接宾语，即need sb. / sth. 例如：
He needs some help. 他需要些帮助。

4. Take a look.
Take a look. 是一个以动词原形开头的祈使句，意为“看一看”。

Take a look.= Have a look.后面接某人或某物时要加at。

例如：
Take / Have a look at these card. 看一看这些卡片。

5. …a good place to meet friends and have fun.
句中不定式短语to meet friends and have fun作后置定语，修饰名词place。

在英语中，动词不定式（短语）作定语，要放在所修饰的词的后面。

例如：
Would you like something to eat? 来点吃的东西好吗？(to eat修饰something)
Mrs. Black has lots of clothes to wash. 布莱克夫人有许多衣服要洗。

(to wash修饰名词clothes) 【句式精练】
