people claiming they are doing ancestry testing.可以这样写吗?

问题描述:

people claiming they are doing ancestry testing.可以这样写吗?
people 【who had claimed 】they are doing ancestry testing.

claiming =>claim 一般现在时,强调的是后面做的内容
然后加个that读起来会舒服点
people claim that they are doing ancestry testing.
或者
claiming =>hava been claiming 现在完成进行时,强调claim这个动作
people hava been claiming that they are doing ancestry testing.claiming 算是动名词吗people claimingthey are doing ancestry testing.

这个句子不对的,分不出主谓宾
语法上对也要这样people are claimingthey are doing ancestry testing.
而即使这样,claiming也不是动名词。
动名词是动词名词化,比如:Eating apples makes us healthy.
