1. 表示两者之中“较...”，用the+比较级+of the two。
I'll give you the bigger of the two steaks; I'm not very hungry.
我要把这块比较大的牛排给你，我不怎么饿。
2. 定冠词或指示形容词+比较级+名词表示比较。
The taller man is the boss of the restaurant and the shorter one is his brother.
那个身材较高的男人是餐馆老板。较矮的那位是他弟弟。
3. 有少数以-ior结尾的属于拉丁语的形容词，如inferior(次于), junior(年幼的;下级的), posterior(之后), prior(之前), senior(年长的,上级的), superior(优于)等本身就有比较的意思，后面不接 than，常与介系词to连用，后面用宾格。
I am two years junior to you.
我比你小两岁。

I am two years your junior.
I am your junior by two years.
I am two years younger than you (are).

be senior to(年长于)+宾格 ?be older than+主格
be superior to(优于)+宾格 ?be better than+主格
be inferior to(劣于)+宾格 ?be worse than+主格
