As the curtain ____ ,the famous singer came out.The fans ____ and screamed with excitement .A. was raised,roseB. had been raised,were raisedC. rose,were raisedD. had risen,raised选哪个?为什么?rise和raise有什么区别?

回答：答案为A。此句句意为;幕布拉开，著名歌手走上舞台。歌迷们全体起立，狂欢起来。
rise和raise是同义词，但rise是不及物动词，而raise是及物动词。
另：rise有“升起”“站起来”的意思；raise有“举起某物”“升起某物”的意思。
又如：
The sun rises in the east.
The audience rose to welcome him.
If you have any questions, just raise your hands.

选A
raise & rise 都有升起,上升的意思.
raise 是及物动词即后面可以加名词 ,也有被动态.rise 是不及物动词,后不可以加名词,不能有被动态.
the curtain 被升起的时候,可以用升起.而粉丝站起来后面没有宾语.所以就要用rise
