问题填空题

本程序的功能是利用随机数函数模拟投币，方法是：每次随机产生一个0或1的整数，相当于一次投币，1代表正面，0代表反面。在窗体上有3个文本框，名称分别是Text1、Text2、Text3，分别用于显示用户输入投币总次数、出现正面的次数和出现反面的次数，如图16-12所示。程序运行后，在文本框Text1中输入总次数，然后单击“开始”按钮，按照输入的次数模拟投币，分别统计出现正面、反面的次数，并显示结果。以下是实现上述功能的程序，请填空。
Private Sub Command1_Click()
Randomize
n=CInt(Text1. Text)
n1=0
n2=0
For i=1 To 【14】
r=Int(Rnd*2)
If r= 【15】 Then
n1=n1+1
Else
n2=n2+1
End If
Next
Text2. Text=n1
Text3. Text=n2
End Sub

答案

参考答案：[14]n [15]1

解析：

[分析]：从填空[14]的位置来看，此处应该放置For循环的循环终值。根据题意，填空[14]为变量n。因变量n1的结果赋给Text2中，n1应放置正面的次数，所以填空[15]应为1。

But it is not easy now to find work. “    30   you speak the language of the country well, there will be very few openings,” says Althea Ellis, an adviser in     31       for students.
“If you work with a family in Italy, you’ll have to speak Italian. When you wash dishes in a restaurant in Pairs, the owner will expect you to speak   32    . British students only have a language     33     for jobs in the USA and Australia.”

The pay was     39     and it really was a 24-hour-a-day job. The kids never slept!”
“The troubles is, students expect to have a(n)     40    time of it.” Althea Ellis points out. “After all, they see it as a    41     .In practice,     42      ,you have to work hard. At the same time, all vacation work is casual (临时的) work. You’ll have a job when the hotel, the restaurant, or the campsite is busy.
