问题 单项选择题

以下______不能实现窗口间的焦点切换操作。

A.在要变成活动窗口的任意位置单击
B.任务栏排列着所有窗口对应的按钮,用鼠标单击某个按钮,则该按钮对应的窗口成为活动窗口
C.利用Alt+Tab键在不同窗口之间切换
D.在桌面空白区域右击,选择“切换窗口”命令

答案

参考答案:D

解析:当多个窗口同时打开时,只有一个窗口是活动窗口,要把另一个窗口变成活动窗口,需要做焦点切换操作。
常用的焦点切换操作方法有:(1) 在要变成活动窗口的任意位置单击即可。(2) 任务栏上排列着所有窗口对应的按钮,用鼠标单击某个按钮,则该按钮对应的窗口成为活动窗口。(3)利用Alt+Tab组合键或Alt+Esc组合键在不同窗口之间切换。在桌面空白区域单击鼠标右键后,出现的快捷菜单中没有“切换窗口”的命令。

It was 1504,and Columbus was making another trip to the New World. Columbus and his men needed fresh water and food after three months at sea. They saw an island and went on shore. On the island there were unfriendly Indians who refused to give food to them. Columbus’ men were afraid of the Indians, but he had a clever plan. He used sign language to tell the Indians about his mysterious (神秘的) power to turn off the light in the sky. He knew about a lunar eclipse (月蚀) the next night because the information was in his almanac (天文历书). Columbus told the Indians, “ Tomorrow night I’ll turn off the light in the sky.” But they didn’t believe him . When the eclipse began the next night ,the Indians became very frightened . They begged Columbus to turn on the light again , and they quickly gave him all the food and water he wanted. Immediately Columbus and his men hurried back to the ship and sailed away in the moonless night.
