问题 共用题干Across the Desert
The Sahara Desert is the largest desert in the world. It stretches across Africa from Senegal to
Egypt. The Sahara Desert is 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 the Sahara.
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(6,920 km).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 the Sahara.
Every morning they began running at 5:00 .At 11 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 a-bout2,000 calories of food each day．Kevin,Ray，and Charlie needed between6,000 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(1 40°F/60℃）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 the Sahara Desert.They hugged each other and put their hands in the water of the Red Sea.Then they ran to a hotel to take a long shower.
选项 The Sahara Desert is not fit for people to live in because of its______.A: extreme weatherB: remotenessC: vastnessD: salty water
答案A
解析根据第一段“The Sahara Desert is an unfriendly environment. During the day it's very hot, and at night it's sometimes very cold.”可知，撒哈拉沙漠不适宜居住的原因是其极端的天气。故本题选A。 由于撒哈拉沙漠极端的天气和缺水因素，跑过撒哈拉沙漠的4, 300英里很显然是一种挑战。故本题选C。 根据第三段的“Every morning they began running at 5:00.”可知，文中的三个人每天早晨5点开始跑步。故C正确。他们是从上午11点到下午5点之间停下来休息，这是一个长时间的休息，故A和B错误。休息后他们继续跑到晚上9:30，故D错误。 由最后一段的“...successfully finished their trip across the Sahara Desert. They hugged each other and put their hands in the water of the Red Sea.”知道，A项正确。 最后一段提到，很多时候，他们想放弃跑步回家，但他们没有放弃。因此，他们成功跑过撒哈拉沙漠的原因是：从不放弃。故D项正确。
