问题 填空题

程序执行结果S的值是 【11】
Private Sub Command1_Click()
i=0
Do
i=i+1
s=i+s
Loop Until i>=4
Print s
End Sub

答案

参考答案:J

解析:[评析] Do……Until语句是先执行循环体,再判断Until后面的条件表达式,当条件为True时,则结束循环。本题中的条件是大于等于4,所以当i=4时,结束循环,此时共执行了4次循环体。所以s=1+2+3+4-10。

     An increasing number of children are flying and traveling around China on their own.

     Eleven-year-old Guo Yongyi quickly finds her place in Row 38 on the three-houi morning flight

from Beijing to Shenzhen , Guangdong province. She takes the window seat and calls for the flight

attendant (乘务员) to ask for a blanket,places her purple backpack under the seat in front of her and

fastens her seat belt. Guo has just spent her summer vacation with a cousin in Beijing and is re-turning

home for the new school term. She is among a growing number of children, aged between 5and 12,

traveling on their own by air during their school holidays. Like Guo , many children make visits to see

family members , while others fly to attend vacation camps.

     Guo first traveled all by herself when she was 7. At that time she had no idea about security

checks or what a boarding gate was. In the plane she was too to ask for a drink or a blanket.

Now, everything is different. She behaves naturally as if she is at home.

    When Guo's flight returns from Shenzhen, it has two other children on the plane, 9-year-old He

Yinnan and 10-year-old Gong Hao.  He, a beautiful little girl with large clear eyes,needs more help.

After finding out He feels sick , Ma Ning , an attendant, gives He a cup of water and suggests that she

takes a walk. "We try our best to become helpful 'aunts' for children," she said.
