prefer的用法是最灵活的

2 prefer to do A rather than do B 愿意去做A而不是去做B
3 prefer to do A rather than doing B 没有这种结构

这个是联接过来的用法
prefer的用法
1、后接不定式时与rather than 或instead of连用，如：He preferred to die rather than (to) steal. / He perferred to die instead of stealing. 他宁死也不去偷窃。
2、注意介词搭配，如： I prefer swimming to skating. (I like swimming better than skating.)我喜欢游泳胜过滑冰。prefer 因其本身含有比较之意，而不可再与more 或most连用。
3、prefer＋名词或动名词“宁愿”，“更喜欢”。He comes from Shanghai, so he prefers rice. 他是上海人，因此更喜欢吃米饭。I prefer going by bike.我宁愿骑单车去。I prefer the white one.我喜欢那个白的。
4、prefer to do “愿意做”。I prefer to go at once.我愿意马上就走。
5、prefer sb. to do “愿意某人做” I prefer you to go at once.我倒希望你马上就走。
6、prefer to sth.“宁愿做...而不做...”. I prefer tea to milk.我宁愿喝茶也不喝牛奶。I prefer watching TV to going out.
我宁愿看电视也不出去。
7、prefer to do sth. rather than do sth.“宁愿做...而不做...” I prefer to watch TV rather than go out.我宁愿呆在家里也不出去。
8、prefer＋ that从句“宁愿”（从句一般用虚拟语气）I prefer that you should do it.我宁愿你做这件事。

Answer 3

prefer后面加动词就两种：prefer doing sth. or prefer to do sth.

用在比较中也只有这两种，而且前后要一致（doing sth.跟to do sth.不可能同时出现在一个比较中。

prefer to do ... than to do...
or
prefer doing ... than doing ...
