一个英文句子中不能出现两个动词吗？

Question

我不知道哪个正确

i think (doing) something meaningful (is) better than stay at home

i think (do) something meaningful (is) better than stay at home

Answer 1

一个英文句子中能出现两个动词，只是动词不能直接开头或独立用，doing和staying是动名词，就可以当作买那个词来用，所以 I think doing something meaningful is better than staying at home才对

Answer 2

A正确，是的一个句子不能同时出现两个动词，今天我们英语老师说了，如果出现第二个动词就要变成动名词或过去分词了

Answer 3

两句都错, 应该是:
I think doing something meaningful is better than staying at home.
