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.

佛陀fótuó：

一位教育家曾这样讲过： “孩子需要鼓励，就如植物需要浇水一样。离开鼓励，孩子就 不能生存。” 周宏是一位普通的技术员， 但是他非常懂得怎样鼓励别人。 他女儿小时候特别不喜欢数 学， （8） 。有一天，周宏给女儿出了 10 道题，结果女儿竟然做错了 9 道。周宏并没有生气， 而是对女儿大加 （9） ：“这么难的题目，你竟然也能做对？我小时候可是一道都做不出啊！ ” 第二天晚上， 周宏（10） 准备了 10 道难度降低了的题目， 再让女儿做， 结果一下做对了 5 道。 他又鼓励女儿说： “天哪，你真是太（11）了！一天之内，你可以进步这么大！ ”第三天，女儿 自己主动要求： “爸爸，今晚我们还做数学题吧？” 半年之后，这个小女孩成了班里的数学课代表。

选项（11）应填（ ）。
