以上他们说的这个句子本身的翻译是不正确的,
个人认为,用现在时就好:(或者,现在进行时也无妨~)
As I grow up,I find out (that)there are a lot of problems appearing because of this.(because of this可省略)
亦可是,As I grow up,I find out a lot of problems appearing.
如果你相信我的话~
一个句子里不可以有两个动词,如果没有连词在的话,所以,有了there are后,肯定不能有appeared的用法,因为它是一个动词~
我也有回答过其他这类似的问题,
