整句改成
It shows the forests of the USA happed 350 years

what has happened to the forests of the USA in the last 350years: 宾语从句, 作shows的宾语。
I know what you are thinking now.
You did what you must do.
整句改成
It shows the forests of the USA happed 350 years
不行。

i dont konw what the hell are you talking

what引导的是宾语从句,表示所发生的事情.所以不能省略.
in the last引导的是时间状语.表示在过去的...时间里.
每个语种都有其习惯,人为地修改了就不是英语了,就像汉语中的:"红旗升起来了"为什么不说"升起来红旗了".
