问题 单项选择题

在窗体中添加了一个文本框和一个命令按钮(名称分别为tText和bCommand) ,并编写了相应的事件过程。运行此窗体后,在文本框中输入一个字符,则命令按钮上的标题变为“计算机等级考试”。以下能实现上述操作的事件过程是( )。

A.Private Sub bCommand Click() Caption="计算机等级考试" End Sub

B.Private Sub tText_Click() bCommanCaption="训算机等级考试" End Sub

C.Private Sub bCommand_Change() Caption=”计算机等级考试”End Sub

D.Private Sub tText_Change() bCommanCaption="计算机等级考试"End Sub

答案

参考答案:D

解析: 题干要求在文本框中输入一个字符的时候,就引发事件,则必须要选择文本框的更改事件,在更改事件代码中,要求改变命令按钮的Caption属性。选项A和选项B分别使用的是命令按钮和文本框的单击事件,不符合题目要求;选项c使用命令按钮的更改事件,也不符合要求:选顶 D使用了文本框的更改事件,并且修改了命令按钮的Caption属性,符合题目要求,故为正确答案。

We each have a memory(记忆力). That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got unusual memories.

A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.

But your memory will become better and better when you do more and more exercises.
