enjoy doing做什么都要加doning吗？

enjoy doing sth 固定搭配

其实就是enjoy +V-ing

V-ing 动名词

不是
enjoy sth/doing sth是固定用法，其他的不一定

The expression “enjoy to” (or “enjoyed to”) is nonstandard, influenced by “like to.” You don’t enjoy to jog; you either enjoy jogging or like to jog.
-------------
应该都是doing.
上面那句话 摘自这一本书 <Common Errors in English> by Paul Brians

Yes,enjoy doing sth,but enjoy sth. it's all right!
