If you are lost in the mountains, stay calm in the face of darkness, loneliness, and the unknown. It will greatly increase your chances of survival (生存). Many people think that preparing necessary equipment and knowing how to use it are very important, but actually eighty percent of mountain survival is your reaction to fear.
Find a hiding place.
Unnecessary labor will make you sweat and make you cold. Find a hiding place around you before trying to start your own construction. If you are in a snow-covered area, you may be able to dig a cave in deep snow for protection from the wind. You should try to hide yourself in the middle of the mountain if possible. Stay out of the valleys — cold air falls, and the valley floor can be the coldest area on the mountain.
Signal rescuers for help.
The best time to signal rescuers is during the day. Signal for help from the highest point possible — it will be easier for rescuers to see you, and any sound you make will travel farther. If you take a box of matches and a space blanket (a special blanket for traveling), build three smoky fires and put your blanket — gold side facing out — on the ground.
Do not walk away.
It will make finding you more difficult, as search teams will be trying to follow your path and may miss you if you have gone off in a different direction. Searchers often end up finding a car with no one in it.
If you get frostbite (冻伤), do not rewarm the affected area until you’re out of danger.
You can walk on frostbitten feet, but once you warm the area and can feel the pain, you will not want to walk anywhere. Try to protect the frostbitten area and keep it dry until you are rescued.

查看习题详情和答案>>A single night of taking the drug Ecstasy (摇头丸) can cause serious brain damage and speed up the start of Parkinson’s disease, scientists say. Just two or three Ecstasy tablets can permanently destroy brain cells that affect movement and reasoning, according to American research that links the drug to Parkinson’s for the first time.
A study by a team at Johns Hopkins University in Baltimore, Maryland, involving squirrel monkeys and baboons (狒狒) found that both species suffered permanent damage to key cells, which are lost in Parkinson’s, after receiving three low doses(剂量)of Ecstasy at three-hour periods.
The study is particularly important because baboons are one of the best animal models for the human brain. George Ricaurte, who led the research, said that the widespread abuse of drug might have caused severe damage. “The most troubling result is that young adults using Ecstasy may be increasing their risk of developing Parkinsonism as they get older.”
Alan Leshner, a former director of the US National Institute on Drug Abuse, said, “This study emphasizes the multi-aspect damage that Ecstasy causes to users. We’ve long known that repeated use damages brain cells. But this study shows that even very occasional use can have long-lasting effects on many different brain systems. It sends an important message to young people: don’t experiment with your own brain.”
Janet Betts, a mother whose teenage daughter Leah died after a single Ecstasy tablet in 1995, said, “This comes as no surprise. But people can’t see the effects at first, and they say it won’t happen to them. We’ll see the symptoms later, just as we have with smoking.”
The article is intended to ______.
A. explain the bad effects of drugs on people’s health
B. warn young people of the risk of taking the drug Ecstasy
C. persuade people out of such bad habits as smoking and using drugs
D. tell us the links between the drug Ecstasy and Parkinson’s disease
We know from the passage that a low dose of Ecstasy ______.
A. won’t cause serious brain damage
B. can permanently destroy one’s brain cells
C. will result in immediate symptoms
D. may bring on Parkinson’s at once
Why are squirrel monkeys and baboons involved in the experiments?
A. Because their brain is similar to human being’s.
B. Because these animals usually take drugs.
C. Because these animals will soon get well after the experiment.
D. Because there is a model in the animals’ brains.
The underlined word “This” in the last paragraph probably means that ______.
A. Leah died after a single Ecstasy tablet in 1995
B. taking drug has the same symptoms as smoking
C. occasional use of the drug can have long-lasting effects on the brain systems
D. people have long known that repeated use of the drug damages brain cells

查看习题详情和答案>>John Steinbeck once said, “All American believe they are born fishermen. For a man to admit to a distaste in fishing would be like speaking publicly against mother-love or hating moonlight”.
I can’t say I’m the biggest John Steinbeck fan. Actually, the only thing I can ever remember read by him was “The Pearl” when I was in middle school, but I couldn’t agree more with the man when it comes to fishing. When I am on a boat in the middle of the lay Lake, fishing off the shores of the Florida Keys for tarpon or catching rainbow trout in the Shoshone River of Wyoming. Fishing is my life.
According to the American Sports Fishing Association, the fishing industry brings in more than $ 116 billion per year from fishermen across the country.
However, fishing is much more than that. Fishing is a way of life for many people and a way to escape everyday stress. Being a fisherman makes me a member of a wonderful group of people extending to all walks of life. Even President Bush can be found fishing on his farm in Texas with his good friend Roland Martin when the jobs gets too stressful.
I can remember fishing with my grandfather when I was 5 years old on his boat at Lake Michel. Although I didn’t understand what I was doing, I did know that my grandfather was happy and that made me happy. Since then I’ve spent the past 16 years on the rivers and lakes of Alabama.
After days of practice, before and after work, I slowly developed an understanding of fishing. My boss, Ric Horst, took me back to the Shoshone, and I managed to bring in a 19-inch cutthroat trout. Fishing with Ric was a life-changing experience for me. He not only showed me how to fish correctly, but also told me how fishing could be a way to escape your problems.
Since then, prime-time season seems to take forever to arrive.
Now, with the ending of February and beginning of March in sight, the excitement of heading out to Lake Tus caloosa or Lake Lurleen before classes and catching something has finally returned.

查看习题详情和答案>>In the past ten years, America’s National Basketball Association (NBA) has grown increasingly dependent on the rest of the world to supply players.
When Michael Jordan and Larry Bird won gold in Barcelona in 1992, the Americans were praised for teaching the world how to play basketball. This season, however, 20 percent of NBA rosters(花名册) will be filled by non-Americans. NBA commissioner David Stem happily embraces the trend. On a visit to Paris in October, Stern outlined his vision for the future, which is likely to see Europe hosting NBA games by 2010.
The NBA is now planning to take China by storm.
“Our experience in China has been that it is going to be explosive in its growth,” said Stern. The strategy(战略,策略) in China is television. “We’ve made 14 deals in China with local and national networks on cable and satellite.” The success of Chinese centre Yao Ming has paved the way for the NBA marketing blitz in China. The NBA, which is broadcasted in more than 200 countries in 42 languages, will put that to the test in October 2004 when the Houston Rockets play two pre-season games against the Sacramento Kings in Beijing and Shanghai. The NBA knows that it needs a global market to compensate for tough times on home soil.
“It doesn’t matter where the players come from, all the NBA teams now know that they have to scout(寻找,觅得) internationally,” said Terry Lyons, the NBA’s vice-president of international public relations. “It has increased the level of competition here.” As Frenchman Tony Parker and Argentine Emanuel Ginobili showed in winning championship rings with the San Antonio Spurs last season, many people can earn the respect of their American peers. Others, such as the Houston Rockets’ Chinese centre Yao Ming — number one draft pick in 2002 — and the Detroit Pistons’ 18-year-old Serb Darko Milicic — number two overall in this year’s draft — are icons(偶像)in-waiting. It is the ultimate(最后的,根本的) revolution — the rest of the world teaching the US how to play basketball.
According to the report, .
A. Michael Jordan is still playing a very important role in NBA
B. the part played by the foreign players in NBA will be great
C. Yao Ming is to play two pre-season games in NBA
