prefer后是to 还是rather than

prefer sth
prefer sth to sth
二次做答
I prefer a policeman to a teacher.
第二句是对的.

prefer sth
prefer sth to sth
prefer sb. to doing sth

prefer A to B,A与B相比更倾向A
rather than也有这个意思

prefer to doing更乐意做。。。。prefer to sth
prefer to do --rather than do--更乐于做。。。比起做。。。

都可以啦!后者比前者强调语气更强

其实都有的
prefer sth to sth
prefer doing sth to doing sth
prefer doing sth rather than do sth
