比较级：more …than… 注意：
1) 比较形式是否正确，如是否有类似"more better"这样重复比较的错误;
2)两者之间是比较级，三者以上是最高级，看看是"两者"还是"三者或三者以上;
3)只有同类的人或物才能比较(可比性);比较不能包括"自己"， 常用other表示排除。
例如不能说：
He is taller than any students in this class.
而应说：
He is taller than any other student(s) in this class.
4)修饰比较级的词有：much, even, far, by far, still, a lot, a bit 等，例如：
John did badly in the sports meet. I did even worse (than John did).
你能看出下句的问题吗?
His salary as a bus driver is more higher than a teacher. ( 他是个公共汽车司机，他的工资要比教师高。)
该句有两个大错1)high的比较级为higher，2)主语his salary(他的工资)而比较对象是a teacher，两者不可比，怎样的表达才是对的呢?请选择：
His salary as a bus driver is much higher ______.
A.in comparison with a teacherB.than a teacher
C.than a teacher's D.than that of a teacher's
正确答案是C，也可以写成than that of a teacher(请联系名词格的概念想一想)
最高级the most of +比较范围 / 最高级+名词+that (不是which)定语从句，例如：
This is the most interesting film that I have ever seen. (这是我看过的最有趣的电影。)
the more…the more… The longer you wear glasses, the more you depend on them. (眼镜戴的时间越长越有依赖性。)
考试时，一般只要认准"the" 和比较级形式就不难判别。
其他表示比较意思的形式
A is superior / inferior to B(A 比B高级 / 低级)
注意：superior/ inferior前不能再加 more 或者less; 用to不是用 than.
例如：
Humans are superior to animals in that they can use languages to communicate.(人比动物高级在于人能用语言进行交际。)
prefer… rather than (宁可…而不…)
例如：
I preferred to stay out in the cold rather than spend the night there. (我宁可呆在外面受冷，也不在那儿过夜。)
Would rather…than… ……(用法和意思与上句型差不多)
