第六课 Important Keys for Controlling MS-DOS(2)MS-DOS重要控制键[2]
1.Pause "Pause" causes MS-DOS to halt a long display to give you time to read the words on the screen.
"Pause" 键能使一个长显示停下来让你有时间读一读屏幕上的内容。
2.Ctrl—Break "Ctrl—Break" cancels a command, but it also stops and cancels a command that you've already told MS-DOS to carry out.
"Ctrl—Break" 组合键能取消一条命令,并且它也能停止并取消已使MS-DOS开始执行的命令。
3.←Backspace "Backspace" moves the cursor one space to the left, at the same time erasing any character it moves over.
"Backspace"键将光标向左移一格,同时删除它移过的任何字符。
New Words & Terms
pause 中止;暂停
cause 导致, 引起
halt 使……停止
long 长的
display 陈列;显示
you 你
time 时间
screen 屏幕
brcak (broke brokon) 打断,中止
that 那个(可作关系代词)
backspace 倒空健
move 使……移动
cursor 光标
space 空,空间
left 左边;左边的
at the same time 同时
erase 擦;拭去
注:1.cancel a command that you've already told MS-DOS to carry out."That you've already told MS-DOS to carry out"是定语从句。在这个定语从句中,主语是you ,谓语动词have told 是完成式。tell MS-DOS to carry out a command “要MS-DOS执行一个命令”。"that" 在从句中作为
carry out 的宾语,这个that 可省去。
2....erasing any character it moves over.这是一个现在分词短语表示同时发生的情况。"it moves over"是定语从句,it 代表the cursor是主语,"moves over"是谓语,它的宾语就是any character,我们可以在这个定语从句前加上充当宾语的关系代词that.
Exercises
记住以下短语:
on the screen, cancel a command, tell MS-DOS to carry out a command, move the cursor, erase a charaier.
