prefer
1.I prefer this to that作“我喜欢这个而不喜欢那个”解，注意to的用法。
2.下面两句意思相同：
- I prefer going to staying.
- I prefer to go rather than stay.
下面几点该注意：
（1）第一句里的to是介词，后面的staying不可改作stay。
（2）第二句里的rather不可省去。
（3）第一句里的to不可改作rather than。
（4）第二句里的rather than stay改作to staying也通，但因为动名词staying和上面的不定式to go不相称，所以不好。
（5）在不说出那不被喜欢的行为的场合，说一次的事用不定式比用动名词普通，如I prefer to go this evening比I prefer going this evening普通。说经常的事用动名词比用不定式普通，如As a rule I prefer going in the evening比As a rule I prefer to go in the evening普通。
3.prefer后面可以接宾语和不定式。例如：Her parents prefer her to study Russian and English.
4.prefer后面可以接以that引导的从句，那从句里用should或虚拟现在式。例如：We prefer that each new student should take this course.和We prefer that each new student take（不用takes）this course.
5.prefer后面可以接宾语和表语。例如：I prefer my milk a little sweetened.
