一、要表達(dá)“還、仍然”的意思時(shí),肯定句和疑問句用still.

“還、仍然”的否定意思有兩個(gè).一是“不再”（指一種習(xí)慣或一種重復(fù)動(dòng)作的終止）.
用no longer (not any longer,no more ,not any more)
He isn't working here any more .I am no more tined.
一是“仍然不”（指無變化的持續(xù)）,用still+動(dòng)詞的否定形式

He still hasn't answered my question.
ever 一般用在疑問句中與完成時(shí)結(jié)合使用表示持續(xù)狀態(tài)
該句子是完成時(shí)態(tài) 與 ever連用 并且沒有持續(xù)到現(xiàn)在意思不用still
