In summer, millions of people will head for the beach．And while the ocean can be a great place to swim and play, it may also be useful in another way．Some scientists think that waves could help make electricity．
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”
Scientists are working on using that energy to make electricity．
Most waves are created when winds blow across the ocean．“The winds start out by making little ripples （波纹） in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said．“Waves are one of nature’s ways of picking up energy and then sending it off on a journey．”
When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine （涡轮） ．The turbine can then power an electrical generator （发电机） ．
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．
The resource is huge．We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal．
Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．
Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．
With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically(心理上) and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
1.One psychological effect of diet products is that people tend to _____.
A. try out a variety of diet foods B. hesitate before they enjoy diet foods
C. pay attention to their own eating habits D. watch their weight rather than their diet
2.In Paragraph 3, “gain comes without pain” probably means ______.
A. losing weight is effortless B. it costs a lot to lose weight
C. diet products bring no pain D. diet products are free from calories
3.Diet products indirectly harm people physically because such products ______.
A. are over-consumed B. lack basic nutrients
C. are short of chemicals D. provide too much energy
A good heart
Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship(奖学金) to study medicine — but Coach(教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”
Success and kindness
After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children’s videos(录像) in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it’s the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”
Bravery and courage
A few weeks ago, Wesley Autrey was waiting at a Harlem subway station with his two little girls when he saw a man fall into the path of a train. With seconds to act, Wesley jumped onto the tracks, pulled the man into the space between the rails(铁轨), and held him as the train passed right above their heads. He insists he’s not a hero. He says: “We have got to show each other some love.”

At one time, people used to travel to foreign countries because they thought they would be different from home—the building, the food, the national dress. Nowadays, however, one large city is very like another. They all have their Hilton or Sheraton Hotels which look Hilton or Sheraton Hotels everywhere. They all have their McDonald’s, their KFCs, their Pizza Huts. Office buildings look the same everywhere, and most city centers are full of office buildings. And, of course, people are driving the same brands of Japanese or European cars, usually wearing the same kinds of clothing and the world’s airlines are all flying the same aircraft, Boeings or Airbuses.
What, therefore, is the purpose of foreign travel for people who are not on business? What do tourists hope to experience in a foreign country that they cannot experience at home? Why travel to foreign countries at all? The answer could be that people are very interested in the past. It is a nation’s history that is its main attraction. Most of today’s tourists travel overseas to find out what foreign countries and cultures used to be like, not what they are like today. The words “cultural tourism” are now part of the language of tourism, and it is the museums and works of art in many countries that are their main attractions.
If they are lucky—and have had sensible, strong governments—many countries also usually have at least a few beautiful places for tourists to visit.
Finally there is perhaps a nation’s greatest attraction: its people. A nation is not just its historical buildings, its works of art or beautiful places, it is also the people who live in it. This is why a country such as Thailand attracts millions of people every year. They come mainly because of the friendliness of the Thai people. It is why the Pacific Islands are also so popular. There may not be much to see or do in Fiji, but there are lots of friendly, smiling people to make visitors feel welcome.

Flying first class was a new experience for us. We were happy to join the other few passengers who 36 fly in such luxury（奢侈）. It was almost as if we had a sense of 37 to be sitting with the group of people that 38 us.
As we chatted away about our travel, I could hear people around us talked about 39 business meetings. It wasn’t long before I __40 that these people were used to flying in luxury. They are 41 people I thought.
We noticed that the stewardess（女乘务员）was working non-stop to ensure the 42 of the first class passengers. She could not walk by a seat without receiving a(n) 43 . I thought how much she must love her job, 44 she smiled kindly at each person while 45 to their needs.
As the stewardess walked by our seats near the 46 of the flight, I looked at her and said, “Thank you and I hope you’ll have a great night.”She stopped at our seats with a look of 47 , bent down, looked at me and said, “Excuse me?” I 48 my words and she smiled in a rather 49 way, almost as if I had asked her a question that she did not know how to answer. After a few moments she said, “I can 50 you work with the public.” “Why do you think so?” I asked. She answered very quietly, “Because you are the _51 passenger here to say thank you and I really 52 your kindess.
The sense of belonging to the elite（精英）group of people in first class 53 as we heard her words. Our seats in luxury offered us 54 a comfortable ride. We were reminded that without 55 we would be flying in no class.
