由对话内容是 CD-ROM卖光了.而不是很好卖（sold well）.所以选择have sold out.然后说“新货到后请立即通知我' 一般期刊,版物发行选择”comes out ”它无被动时态
对话内容：
A（某公司销货员）：对不起,教学光盘已经被卖光了.你下周再来好吗?
B（顾客）………（留下了自己的联系电话）新货到后请立即通知我'

2.A
由题意知道 鼠标用来移动荧屏上的光标位置.“用作什么之用"选择use for 但mouse（鼠标）在这儿是物,作主语要用被动时态,所以为is used for .而for是介词.move要写成ing形式.
主要区分二个短语 used to 表示过去一向,过去时常;过去曾(暗含着而现在不再)做
be used to 习惯于做某事 be used for被用来做某事 后面常跟名词或V+ing.
A：.鼠标的功能是什么?
B: 它用来移动荧屏上的光标位置.
