takepartin后面加do还是doing

take part in 这是个动词词组。这个词组最后一个词in是一个介词，所以它的后面要求跟着使用的词为名词。即为take part in sth. 或take part in doing sth.

例如

We have come here to take part in a major game. 我们来这里参加一项重要比赛。

Did you take part in planting trees last week? 你上星期参加种树了吗

take part in 后面加doing. 例: I will take part in a basketball match this afternoon.
