英语的一个疑问

有点问题，take part in后面应该加一个名词才完整，如果没有名词，只要用take part或者participate就可以了
即：A new program called KatySat aims to get teenagers to take part / participate.

A new program called KatySat aims to get teenagers take part in.
个人认为应该去掉第二个to，get sb. do。

对

A new program called KatySat aims to get teenagers taking part in

句中有两个动词了

我的意见是：
A new program called KatySat aims at getting teenagers take part in.
