2--No，it is the original one.
 
1--This is silver gray，while I remember your handset was black.
 
2--I have changed a case for it.
 
1--Can a handset case be changed
 
2--Of course. That's why I bought this type. I can change its case fre-quently，so it is novel to use it.
 
1--How  many cases are accessible?
 
2--There are two more，one is orange and the other is pink. I have bought them all.
 
1--It's really going to be fresh all the time.

1--哎，你又买了一部手机吗?
2--哪儿呀,是原先的那个。
1--怎么变银灰色了，我记得你的手机是黑色的。
2--我给手机换了个外壳。
1--手机的外壳能换?
2--那当然了，当初买的时候就看中了这一点，经常换个外壳，用着也觉得新鲜。
1--能换几种外壳?
2--还有两种，一种是橙色的，另一种是粉红色的，我全买了。
1--这可真是常用常新。
