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. changechange 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.四、 练习1.
