三、精讲课文

1、How much does it cost? = How much is it? 多少钱。 cost 花费，主语是物。例句：The book costs ten yuan.

2、It's the most expensive model in the shop. 形容词的最高级。多音节词：expensive-more expensive-the most expensive 单音节词：dear-dearer-the dearest

3、It costs five hundred pounds. 具体几百：two hundred students 大约数百：hundreds of students

几百元钱：five hundred pounds/dollars/yuan

4、That's too expensive for us.【回顾Lesson 103】

5、We can't afford all that money.

afford some money/time负担得起（金钱/时间），及物动词。例句：We can’t afford that television. He’s too busy and he even can’t afford an hour for lunch.

6、This model's less expensive than that one. 形容词的最高级。多音节词：expensive-less expensive-the least expensive 单音节词：cheap-cheaper-the cheapest

7、It's only three hundred pounds. 注意副词only的位置。

8、It's not as good as the expensive one.

as...as... 和…一样…；not as...as... 不如…那样…例句：The French test is as difficult as the English test.

He is not as tall as his brother. He doesn’t run as fast as his brother. 9、The other model's more expensive, but it's worth the money.

the other 两者之中的另一个。worth [adj.] 值得，后加金钱或时间。

10、Can we buy it on instalments?

buy sth. on instalments用分期付款的方式买东西。例如：He bought his house on instalments.

11、You can pay a deposit of thirty pounds, and then fourteen pounds a month for three years. pay 支付，主语是人。例句：I paid two yuan for a drink.

a deposit of... …的预付定金。a deposit of 30%。bank deposit 银行存款。

and then 然后。...a month 每月（付）多少，月供…。for + 时间段：持续多长时间。

12、Do you like it, dear?

这里的dear不是“贵”的意思，而是“亲爱的”= darling = honey

13、I certainly do, but I don't like the price.

certainly = of course 当然。这里的do代指的是like it，助动词相当于实义动词的影子。 price 价格，价钱。例如：The price is high/low.

What’s the price of the television? It’s worth the price.

14、You always want the best, but we can't afford it.

always 总是，一直。一般现在时的标志性频率副词。the best (television/thing)

15、Sometimes you think (that) you're a millionaire! 宾语从句。

sometimes 有时。一般现在时的标志性频率副词。think 想，以为。

16、Millionaires don't buy things on instalments! 故作严肃，英国人的小幽默。
