小明同学在练习用电流表测电流的实验中，记录了测量结果是2.1A，同桌的小锋发现他的测量结果与小明的测量结果相差较大，于是寻找电路原因，终于发现小明是以0.6A的来量程测量，而问题出在读数时却按3A的量程读数，则小明的实际测量值应为（　　）

杭州市民卡是一张集成电路卡，具有信息储存、身份识别、电子支付等功能。每位市民卡的卡号是唯一的，卡内会记录每位市民的姓名、住址、金额等信息。

假设共有100000个市民，市民的卡号、姓名和金额分别存放在数组a、b和数组c中，a(i)是存放第i个市民的卡号，则对应的第i个市民的姓名存放在b(i)中，金额存放在c(i)中。

通过卡号查询其姓名和余额的程序界面如图所示。在文本框Text1中输入卡号，单击“开始查询”按钮，如果找到，就在Label1中显示卡内市民姓名和金额；否则显示“查无此人”。已知卡号按照从小到大排序。请按要求将下列程序补充完整。

Dim a (1 To 100000) As long

Dim b (1 To 100000) As string

Dim c (1 To 100000) As long

Private Sub Command1_Click()

Dim x As Long, i As Long, j As Long, m As Long, f As Boolean

x = Val(Text1.Text)

i = 1: j = 100000: f = False           、

Do While  i<=j and f=false       

          ①        

If x= a(m) Then

        f = True

    ElseIf x< a(m) Then

        j = m - 1

    Else

             ②       

    End If

 Loop

 If f=false Then

        Label1.Caption =”查无此人”

    Else

         Label1.Caption = b(i)+ "卡内余额为"+ Str(c(i)) + "元"

    End If

 End Sub

   About 21,000 young people in 17 American states do not attend classes in school buildings.
   Instead, they receive their elementary and high school education by working at home on computers. The center for Education Reform says the United States has 67 public “cyberschools(网络学校)” and that is about twice as many as two years ago.
   The money for students to go to a cyberschool comes from the governments of the states where they live. Some educators say cyberschools receive money that should support traditional public schools. They also say it is difficult to know if students are learning well.
Other educators praise this new form of education for letting students work at their own speed. These people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say learning at home by computer ends long bus rides for children who live far from school.
   Whatever the judgment of cyberschools, they are getting more and more popular. For example, a new cyberschools called Commonwealth Connections Academy will take in students this fall. It will serve children in the state of Pennsylvania from ages five through thirteen.
Children get free equipment for their online education. This includes a computer, a printer, books and technical services. Parents and students talk with teachers by telephone or by sending emails through their computers when necessary.
   Students at cyberschools usually do not know one another. But 56 such students finished studies at Western Pennsylvania Cyber Charter School recently met for the first time. They were guests of honor at their graduation.

小明在班内的人缘一直不好，为了改善这一状况，他找到比自己高一年级的表哥，表哥说：你别管了，这事包在我身上。事后，表哥带着几个好朋友到弟弟的班内，扬言谁要是不和他弟弟玩就有他的好看。班主任老师严肃地批评了小明，并耐心地教给他一些与人相处的方法。这一事例说明（   ）
