打开窗体Form1后,在Text1和Text2中分别输入5和10,然后单击命令按钮Comrnand1,则Text3中显示的内容为______。

答案

参考答案:510

解析: 本题考查运算符的使用。“+”运算符可以用于计算机两个数之和,也可以使用“+”运算符连接两个字符串,“+”运算符两端的表达式的基本类型决定了“+”运算符所做的操作,如果两个表达式都是数值或者一个表达式是数值,另一个表达式是字符串,则“+”代表相加;如果两个表达式都是字符串则“+”代表字符串,所以“+”运算符连接的是字符串“5”和字符串“10”,所以本题答案为510。

     English is fast becoming the language of science around the world, but what is its future among

everyday speakers? One expert points out that the percentage(比率) of native English speakers is

declining (降低) globally while the languages of other rapidly growing regions are being spoken by

increasing numbers of people. But English will continue to remain widespread and important.     

     However, British language scholar David Graddol says English will probably drop in dominance (主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. "The

number of people speaking English as a first language continues to rise, but it isn't rising nearly as fast as the numbers of many other languages around the world, simply because the main population group has been

largely in the less developed countries where languages other than English have been spoken,' he says.    

     In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the

top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay,

spoken in south and Southeast Asia.     

     David Crystal, the author of the Cambridge Encyclopedia of the English Language, says about 1.5

billion of the world's six billion people speak it as a second tongue compared to the 400 million native

speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future

of its dominance. "Nobody quite knows what's going to happen because no language has been in this

position before. But all the evidence (证据) suggests that the English language snowball is rolling down a

hill and is getting faster,' he said.
