Across the Deserts

  The SaharaDesertis the largest desert in the world. It stretches across Africa fromSenegaltoEgypt. TheSaharaDesertis an unfriendly environment. During the day it"s very hot, and at night it’s sometimes very cold. It is also difficult to find water in theSahara.

  In 2006, Kevin Lin, Ray Zahab, and Charlie Engle decided to do something very difficult. They made the decision to run across the Sahara Desert 4,300 miles (6,920km). It seemed impossible to do, but they wanted to try. The three men liked to test themselves, and this would be a very big test.

  On the morning of November 2, Kevin, Ray, and Charlie started their trip across theSahara. Every morning they began running at 5:00. At11 a.m. they stopped and rested until 5 p.m. Then they ran again until 9:30 in the evening. Each day they ran about 40 miles (64 km). Every day it was the same thing. They got up and ran. They listened to music on their iPods, and they ran and ran.

  Kevin, Ray, and Charlie needed to eat a lot of food during their trip. Most people need about 2,000 calories of food each day. Kevin, Ray, and Charlie needed between 6,000 and 9,000 calories every day. That"s a lot of food! They also needed to drink a lot of water.

  The three men had some problems on their trip, and many times they wanted to quit and go home. It was often very hot (140°F/60°C) during the day, and the heat made them sick. Their legs and feet hurt. Sometimes it was very windy, and they couldn"t see. One time they got lost. But they didn"t quit. After 111 days, Kevin, Ray; and Charlie successfully finished their trip across theSaharaDesert. They hugged each other and put their hands in the water of theRed Sea. Then they ran to a hotel to take a long shower.

分辨率为1024×768的显示卡,显示64K种颜色,则该显示卡显示内存至少为()。

A:64K B:256M C:768K D:2048K

某人编写了下列程序,用来求10个整数(整数从键盘输入)中的最大值: Private Sub Command1_Click( ) Dim a(10) As Integer, max As Integer For k=1 To 10 a(k)=InputBox("输入一个整数") Next k max=0 For k=1 To 10 If a(k)>max Then max=a(k) End If Next k Print max End Sub 运行程序时发现,当输入10个正数时,可以得到正确结果,但输入10个负数时结果是错误的。程序需要修改。下列修改中可以得到正确运行结果的是( )。

A:把Ifa(k)>max Then 改为 If a(k)<max Then B:把max=a(k)改为a(k)=max C:把第2个循环语句For k=1 To 10改为For k=2 To 10 D:把max=O改为max=a(10)

下面程序的输出是______。 main( ) {int k=11; printf("k=%d,k=%x/n",k,k,k); }

A:k=11,k=12,k=11 B:k=-11,k=13,k=13 C:k=11,k=013,k=0xb D:k=11,k=13,k=B
