问题：Therearetwelvepeopletakingpartin? 
There are twelve ople taking part in the experiment, four working as a group.为什么要用taking 这个分词做定语?直接take part 不可以吗?
回答：There are twelve people taking part in the experiment, four working as a group.

这句话的意思是与12个人参加这个实验,4个人一组.

现在分词做后置定语,因为people 和take part in 这个动词是主动关

系,所以就用现在分词形式.
