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.

参考答案
参考解析
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。

Health Education1.Health education is the part of health care that is concerned with promoting healthy behavior. A person's behavior may be the main cause of a health problem,but it can also be the main solution. This is true for the teenager who smokes, the mother with the poorly nourished（营养） child, and the butcher（屠夫，卖肉的人）who gets a cut on his finger. By changing their behavior these individuals can solve and prevent many of their own problems.2.Health education does not replace other health services,but it is needed to promote the proper use of these services. One example of this is immunization（免疫）:scientists have made many vaccines（疫苗）to prevent diseases,but this achievement is of no value unless people go to receive immunization.3.Health education encourages behavior that promotes health,prevent illness,cures disease and contributes to recovery. The needs and interests of individuals,families,groups,organizations,and communities are at the heart of health education programs.Thus there are many opportunities for practicing health education.4.Health education is not the same thing as health information.Correct information is certainly a basic part of health education,but health education must also address the other factors that affect health behavior such as availability（可获性）of resources, effectiveness of community leadership, social support from family members,and levels of self-help skills.Health education therefore uses a variety of methods to help people understand their own situations and choose actions that will improvetheir health. Health education is incomplete unless it encourages involvement and choice by the people themselves.5.Also,in health education we do not blame people if they do not behave in a healthy way. Often unhealthy behavior is not the fault of the individual.In health education we must work withfamilies,communities,and even regional authorities to make sure that resources and support are available to enable each individual to lead a healthy life.Individuals should be provided with necessary conditions for______.A:disease preventionB:health educationC:healthy behaviorD:unhealthy behaviorE:other health servicesF: many vaccines

In Sports,Red is the Winning ColorWhen opponents of a game are equally matched,the team dressed in red is more likely to win,accord- ing to a new study.British anthropologists Russell Hill and Robert Barton of the University of Durham reached that conclu- sion by studying the outcomes of one-on-one boxing,tae kwon do,Greco-Roman-wresting,and freestyle- wrestling matches at the 2004 Summer Olympics in Athens,Greece.In each event Olympic staff randomly assigned red or blue clothing or body protection to competitors. When otherwise equally matched with their opponent in fitness and skill,athletes wearing red were more likely to win the bout."Where there was a large point difference一presumably because one contestant was far superior to the other一color had no effect on the outcome,"Barton said."Where there was a small point difference,the effect of color was sufficient to tip the balance."In equally matched bouts,the preponderance of red wins was great enough that it could not be attributed to chance,the anthropologists say.Hill and Barton found similar results in a review of the colors worn at the Euro 2004 international soccer tournament.Their report will be published in tomorrow's issue of the journal Nature.Joanna Setchell,a primate researcher at the University of Cambridge in England,has found similar results in nature.Her work with the large African monkeys known as mandrills shows that red colorationgives males an advantage when it comes to mating.The finding that red also has an advantage in human sporting events does not surprise her,adding that "the idea of the study is very clever."Hill and Barton got the idea for their study out of a mutual interest in the evolution of sexual signals in primates一“red seems to be the color,across species,that signals male dominance and testosterone levels," Barton said.For example,studies by Setchell,the Cambridge primate researcher,show that dominant male man- drills have increased red coloration in their faces and rumps. Another study by other scientists shows that red plastic rings experimentally placed on the legs of male zebra finches increase the birds'dominance.Barton said he and Hill speculated that"there might be a similar effect in humans.And if so,it could be apparent in sporting contests."The pair say their results indicate that sexual selection may have influenced the evolution of humans' response to color.Setchell,the primatologist,agrees."As Hill and Barton say,humans redden when we are angry and pale when we're scared.These are very important signals to other individuals,"she said.The advantage of red may be intuitively known,judging from the prevalence of red uniforms in sports一 "though it is clearly not very widely appreciated,on a conscious level at least,"Barton said.He adds that the finding of red's advantage might have implications for regulations that govern sporting attire.In the Olympic matches he surveyed for the new study;for example,it is possible some medal winners may have reached the pedestal with an unintended advantage."That is the implication,though we cannot say that it made the difference in any specific case,"Bartonsaid.Meanwhile,Setchell noted一tongue-in-cheek一that a red advantage may not be limited to sports. "Going by the recent U.S.election results,red is indeed quite successful,"she said.Hill and Barton believe athletes in red are more likely to win.A:RightB:WrongC:Not mentioned

A Heroic WomanThe whole of the United States cheered its latest hero,Ashley Smith,with the Federal Bureau of Investigation saying it was planning to give a big reward to her for having a brave heart and wise mind._______(46)She was moving into her apartment in Atlanta,Georgia early on the morning of March 12,when a man followed her to her door and put a gun to her side."I started walking to my door,and I felt really,really afraid,"she said in a TV interview last week.The man was Brian Nichols ,33.
