三、Grammar points
1.How much does that pen cost?
= How much is that pen?
那支笔多少钱？
我们想要问某物品多少钱时，可以用下列句型：
How much does+单数物品/ do + 复数物品 cost?
=How much is+单数物品/ are + 复数物品?
例：How much do these pencils cost?
= How much are these pencils?
回答时用：
It costs ….或 It is …
2.cost 表示“价值（多少钱）”，使用这个字时，不可以用人做主语，
通常用物品，东西等做主语，表示某物品或东西价值多少。

例：The dress costs twenty dollars.
我们也可以在cost后接人，再加上金钱，表示话某人多少钱的意思。

例：This hat cost her thirty dollars.
3.That’s very expensive.
Expensive 是形容词，表示价格昂贵的，多用来修饰物品，而不能用来修饰价钱（price）.
例：The price of the car is expensive. (错误)
The car is expensive.(正确)
价钱的昂贵或便宜可以用high(高)或low（低）来表示。

The price of the house is high.
= The house is expensive.
Eggs are selling at a low price.
4.Do you have anything cheaper?
句中的anything 表示任何事物的意思，与something(某事，某物)及nothing(没有东西)均为代词，可以用来代替事情或物品。

Anything 使用于否定句及疑问句中，而something则使用于肯定句中，nothing 因本身具有否定意味，因此不可再用否定词（not,no等）连用，以避免形成双重否定。

例：The poor man doesn’t have nothing to eat.(错误)
The poor man has nothing to eat.(正确)
=The poor man doesn’t have anything to eat.
另外，当有形容词修饰something，anything，nothing时要至于这三个词后，不能至于其前。

例：Do you have anything important to tell me?
There is nothing nice to eat in that restaurant.
5.I’ll take it.我就把它买下了。

例：A: This book is very good. You should buy it.
B: All right. I’ll take it. = I’ll buy it.
6.change
change 做动词意思为变化
例：The lights changed from red to green.
但在这里意思是零钱, 和money一样是不可数名词。

例：How much change do you have?
I have change for ten dollars.
7. Here’s the money. 钱给你。

当我们要给别人东西时，可以用下面句型：
Here’s / Here is + 单数名词
Here’re / Here are + 复数名词
意为“…给你”
例：Here are the books.
但更常用的一句话是Here you are. 意为给你，拿去吧。

例：Can I have a look at that shirt?
Here you are.
Can you give me the invoice？
能不能给我一张发票？
常听到有人在问发票这个字的英文怎么讲？就是invoice 这个字啦！只可惜在美国买东西一般都只给收据receipt。
