题目:

本程序的功能是利用随机函数模拟投币,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。在窗体上有三个文本框,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,如图所示。程序运行后,在文本框Textl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
r=Int(Rnd*2)
If r = Then
n1 = n1+1
Else
n2 = n2+1
End If
Next
Text2.Text = n1
Text3.Text = n2
End Sub

When I was 17, I read a quote that went something like:"If you live each day as if it were your last, someday you’ll most certainly be right." It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself, "If today were the last day of my life, would I want to do what I am about to do today "
Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life.
About a year ago I was diagnosed with cancer. The doctors told me this was almost certainly a type of cancer that was incurable, and that I would live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor’s code for preparing yourself to die.
I lived with that diagnosis all day. I was completely in despair. Later that evening I had another biopsy and my wife told me that tumor turned out to be curable with surgery. I had the surgery and I’m fine now.
This was the closest I’v been to facing death. To tell the truth, no one wants to die. And yet death is the destination we all share. No one has ever escaped it. It clears out the old to make room for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away.
Your time is so limited that you shouldn’t waste it repeating someone else’s life. Don’t be trapped by dogma-which is living with the results of other people’ s thinking. Don’ t let the noise of others’ opinions drown out your own inner voice. And most important, have the courage to follow your heart. It somehow already knows what you truly want to become. Everything else is secondary.

The doctor advised the author to go home and get his affairs in order because______.

A. he had to rest at home
B. his disease couldn’t be cured
C. his disease was not serious at all
D. he had to wait for the result of the rest
