比较级与最高级 · PET / B1
天天向上 · 原创语法学习讲义
比较真实选项：描述差距、相等与最突出者，并用信息支持选择。
形成比较级
短词常加 -er / -est；较长形容词常用 more / most；也有不规则变化。
good → better → best; bad → worse → worst
好、更好、最好；差、更差、最差。
不要同时使用 more 和 -er：more cheaper 错误。
比较级与最高级
than 引出比较对象；最高级通常加 the，并配合 in / of 说明范围。
It is the safest of the three routes.
这是三条路线中最安全的一条。
比较对象要一致，如 my bag 与 yours，而不是把包与人直接比较。
as…as 用原级
as + 形容词或副词原级 + as 表相等；not as…as 表不及。
Mia runs as quickly as her brother.
米娅跑得和哥哥一样快。
描述动作方式用副词 quickly；结构中不写 more quickly。
修饰差距
much、far、a lot 可加强比较；a bit、a little 表小差距；less / the least 表程度较低。
This option is less expensive, but the other one is far more comfortable.
这个选项价格较低，但另一个舒服得多。
very 修饰原级，不能直接说 very better。

参考表达
The photography club is more expensive than the art club, but it provides all the equipment. The art club is a little closer to my home, so travelling there is easier. Both clubs are as friendly as each other, but the photography club offers more outdoor activities. I think it is the better choice for me because I enjoy exploring new places and would like to learn to use a camera properly.
