每课一句：新概念英语第1册第111课
接下来，我们就来看看第111课的“每课一句”。
一、课文原文
Lesson 111 The most expensive model
I like this television very much. How much does it cost?
It’s the most expensive model in the shop. It costs five hundred pounds.
That’s too expensive for us. We can’t afford all that money.
This model’s less expensive than that one. It’s only three hundred pounds. But, of course, it’s not as good as the expensive one.
I don’t like this model. The other model’s more expensive, but it’s worth the money.
Can we buy it on instalments?
Of course. You can pay a deposit of thirty pounds, and then fourteen pounds a week for three years.
Do you like it, dear?
I certainly do, but I don’t like the price. You always want the best, but we can’t afford it. Sometimes you think you’re a millionaire!
Millionaires don’t buy things on instalments!

二、每课一句
But, of course, it's not as good as the expensive one.
本课继续学习形容词和副词的比较关系，只是本课侧重学习的是同级比较（即原级比较）的用法。
同级比较主要用来表达“...与...相比，一样得...”，它主要有两种用法：
1、A+be+as+形容词+as+B
如：
He is as tall as Jack.
2、A+do+as+副词+as+B
如：
He jumps as high as Jack.
【注意】
其否定表达为：
not as/so ... as ...
如：
He is not as/so tall as Jack.
He does not jump as/so high as Jack.
三、更多拓展
It's the most expensive model in the shop.
本课出现了三音节及以上的形容词和副词的比较级和最高级的变化规则，这些形容词和副词的比较级是通过“more/less+形容词或副词的原形”来表达的，其最高级是通过“the most/least+形容词或副词的原形”来表达的。如：
expensive, more/less expensive, the most/least expensive
beautiful, more/less beautiful, the most/least beautiful
carefully, more/less carefully, the most/least carefully
大家可以参考我在第107-108课和第109-110课里有关比较关系的内容分享：
