news 不可数,不能直接加two,必须用 two pieces of news

不能这么改，news是不可数名词

口语中可以这样说，意思不会变。书面语及考试时，要避免使用。

news是不可数的，可以用两次表示吗？不可以的呀，所以你下面本来就存在语法错误

没有这种用法

如果英文很烂，这种说法还过得去。外国人应该能懂。只是，你的问号有点问题。从语法角度说，当然就错了。

不可改

意思不变,但语法角度看是错句.news虽然结尾有个S,但它是个固定的词语,意
思是"新闻",并且不可数的.诚如,要表达几则,一定要应固定搭配"
pieces of news"且news前不可用two之类的具体数词.
