推 aowen:因為後面是名詞...不是子句 用for吧
→ priv:#2 did 代替suffer所以不是was
→ priv:sorry回錯篇
→ chenzhishun1:people say that all the time, but it is not
→ chenzhishun1:considered proper english
→ chenzhishun1:replacing"why"with"for"is one way to correct it.
→ chenzhishun1:mm.. let me take it back... people probably don't
→ chenzhishun1:say it all the time...
→ chenzhishun1:aowen is right, sorry didn't see it
