American like to visit the national parks. In 1996, over 250,000,000 people visited areas run by the National Park Service. Experts predict that by 2010, 500,000,000 people per year will visit the parks. As a result, people are trying to think of ways to protect the parks from the crowds.

   The crowding of the parks has caused several problems. One is that there is not enough space for all of the people who want to use the parks. To cope with this problem, national parks may require reservations months in advance for some spots. The Park Service may also raise entrance fees at these places.

    Another problem caused by increased park use is pollution. Some garbage and waste can be cleaned up, and the cleanup can be paid for by increased entrance fees. To cut down on noise pollution and air pollution, officials may decrease the number of cars allowed in parks. If this happens, people may use buses to travel around the parks. Officials may also limit the use of jet-skis, snowmobiles (摩托雪橇), motorboats, and sightseeing helicopters and planes.

    The parks are also threatened by development that is going on around them. For example, around Yellow Stone Park, many motels (汽車旅館), golf courses, resorts, and other tourist attractions have been built. Some of these developments affect areas that are used by animals. People will have to learn to agree about ways to protect the parks. If they do not, there will soon be no reason to visit these national treasures.

By 2010, the number of visitors will rise by ______ per year.

A. 250 million              B. 500 million              C. 2.5 billion         D. 5 billion

Entrance fees may be increased _______.

   B. either to limit the number of visitors or to pay for the cleaner

C. not only to protect the animals but to reduce the noise pollution

D. merely for the development of the national parks

Almost all theme park accidents can be prevented．Here, based on coverage of theme park safety, are some tips to help you and your family stay safe on your next visit.

If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.

Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do． 

Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.

“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”

How to Be a Winner

Sir Steven Redgrave

Winner of 5 Olympic Gold Medals

       “In 1997 I was found to have developed diabetes （糖尿�。� ．Believing my career （職業(yè)生涯）was over, I felt extremely low．Then one of the specialists said there was no reason why I should stop training and competing．That was it----the encouragement I needed．I could still be a winner if I believed in myself．I am not saying that it isn’t difficult sometimes．But I wanted to prove to myself that I wasn’t finished yet．Nothing is to stand in my way．”

Karen Pickering

Swimming World Champion

       “I swim 4 hours a day, 6 days a week．I manage that sort of workload by putting it on top of my diary．This is the key to success—you can’t follow a career in any field without being well-organized．List what you believe you can achieve．“Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them．”

Kirsten Best

Poet ＆ Writer

       “When things are getting hard, a voice inside my head tells me that I can’t achieve something．Then, there are other distractions, such as family or hobbies．The key is to concentrate．When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind．It makes me feel more in control and increases my confidence．This is a habit that can become second nature quite easily and is a powerful psychological （心理的） tool．”

We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets. 

Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO₂）and other greenhouse gases that are trapping heat in our atmosphere.  21世紀(jì)We decided to try an experiment. For one month we recorded our personal emissions of CO₂^. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO₂ a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce? For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO₂ emissions by 80 percent,” he said. 

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary. 

Why did the author and his wife try a new diet?

A. To take special kinds of food          B. To respond to climate change. 

C. To lose weight                      D. To improve their health

The underlined words “tipping points” most probably refer to  .

A. freezing points       B. burning points       C. melting points     D. boiling points

It can be inferred from the passage that 2___.   ..

A. it is necessary to keep the air-conditioning on all the time ..

B. it seems possible for every household to cut emissions of CO₂

C. the average US household produces about 3,000 pounds of CO₂ a month.

D. the average European household produces about 1,000 pounds of CO₂ a month.

Which of the following would be the best title for this passage?

 A. Saving Energy Starts at Home         B. Changing Our Habits Begins at work

 C. Changing Climate Sounds Reasonable  D. Reducing Emissions of CO₂ Proves Difficult
