二：表示对比，比较

1：以-ior结尾的形容词，后接介词to表示比较，如：superior ,inferior,prior,senior,junior

2: 一些本身就含有比较或比拟意思的形容词，如equal，similar，equivalent，analogous

3：表示一些先后顺序的形容词，如：second,subsequent,next,preliminary,preparatory

4: to也偶尔出现在个别动词之后,与动词形成固定词组,表示比较,如:prefer to,compare to,in contrast to

compare to sth.表示比喻或比拟,而compare with sth.表示比较,如:

World is usually compared to a stage

Compared with his past,he has changed a lot.

Prefer的正确句型是:prefer A to B或prefer doing A to doing B,但当prefer后接动词不定式时,表示比较的介

词to就要改成rather than ,如:

8: 另外还有一些名词符合这种用法,有的具有两者息息相关,缺一不可的含义.如:key to door,invitation to

party,

guide to action,limitation to life,accessory to school

be back to 是“回到......”的意思，如果用不定式to think 则是“回来做......"的意思。两者意思大不一样。

说实话，本人也十分不能理解这里的think为什么不用原形…这个to明显的不是介词啊！？还有前面的第一句话，spend和thinking用and连接？？楼主你有没有想过，这句话原本就是错的呢？
