问题 单项选择题

A.把该文档的内容从外存储器读入内存并显示出来

B.为该文档开设一个新的、空的文档窗口,准备编辑该文档

C.把该文档内容从内存中读出并显示出来

D.显示并打印该文档的内容

答案

参考答案:A

解析:文件一般都保存在外存储器上,而不是保存在内存中。因此在Word 2000中,一般意义上打开一个文件的含义是“把文档的内容从外存储器读入内存,并显示出来”。其他说法都不正确。

     What could be simpler than shaking fruit from a tree? Well, the job is a lot more difficult than you

might think. There is a right way and a wrong way to shake a fruit tree. And a person who is a good

apple tree shaker may not be a good cherry tree shaker. Different fruits take different shakes .

     As a rule, a slow hard shake is best. This makes the fruit fall much faster than a light; quick jiggle.

Most fruits have a set number of shakes per minute that will do the best job of getting them out of the

tree and onto the ground. To shake down plums, try shaking the tree four hundred times per minute,

moving the tree two inches at each shake. Experts say you'll get three times more fruit from the tree than

you will if you shake eleven hundred times per minute at one inch per shake. Cherries, because they are

smaller, need more shaking. A good rate of shaking seems to be about twelve hundred shakes per minute. Apples, like plums, need four hundred shakes.

     Of course, some people may choose to take no notice of all these expert directions for shaking fruit.

Keeping track of all the numbers can be enough to drive some people up a tree.
