优质解答

要先确认,后半句
tell them (what) you concerns,中 you 是否为your?
如果是your,那么concerns,这里是名词,意思是：关心的事情
your concerns,你关心的事情,前面不可以加 what.
但是可以 加 what're = what are
you should talk it with your parents and then tell them (what're) you concerns
而 concern又可以作为动词,这里 如果 concerns不加s的话,应该加 what
you should talk it with your parents and then tell them what you concern
