① "as +原级形容词+as"的布局，暗示前后两者的环境一样
eg. Bill is as funny as his father.
My handwriting is as beautiful as yours. 我的书法和你的一样好。
eg. Lucy speaks Chinese as well as Lily.
② 在否认句中，用"not as/ so +原级形容词as"布局，暗示前者不如后者。
eg. These books aren't as interesting as those.
I am not as/ so busy as I used to be. 我没有已往那么忙了。
eg. She didn't sing so well that night as she usually does.
③ 如若第一个as/ so后的形容词作定语修饰名词，应将该名词及有关修饰语都放在第一个as/ so之后。
We have produced as many tractors as we did last year. 我们出产的拖拉机和去年一样多。
I don't make as/ so much money as you do. 我挣得钱不如你挣得多。
