prefer to do sth.& prefer doing sth.的区别
我想问问一道题什么时候用prefer to do sth.than do sth.
什么时候用 prefer doing sth than doing sth.
For example :
I prefer ( ) than ( ).
那是填 running ; swimming 还是填 to run ; swim

答案

prefer doing A to doing B
Even on holidays Mr.Wang preferred reading to doing nothing.即使在假日,王先生宁愿读书而不愿闲着.
prefer to do sth.rather than do sth.
These workers prefered to work extra hours at night rather than leave the work until the next week.这些工人宁愿加班干,也不愿把工作留到下一个星期.
所以你那句应该是填 to run ; swim
