你說了三句話，每句都有語病：

首先，“Since your examples were poorly demonstrated due to the fact which you don\'t have a proper translation skill.”是一個不完全句，沒有主句。其中fact後只能用that,不能用which。為什麼呢？因為這裡的that 引起的是同位語。

其次，\"suggest\"後面，要麼跟that從句，要麼跟 doing，決不可跟不定式。

最後，\"One of the obvious mistake\" 里的“mistake\"應用複數“mistakes\"。
