like后面的动词如果是个都加ing?

看情况.如果是已完成的,或者是一般情况的,就要加.
例：I like running and swimming.
He likes playing computer games.
如果未完成,只是想法,就不必加.
例：I like swimming,but I like to play football with you this afternoon.
like doing 更强调爱好,也就是一贯的行为；
而like to do 则强调一次性的动作.
改疑问句：Do you like playing computer games?

只加一个

like running and swimming
