阅读下面的短文，根据短文后的要求答题(请注意问题后的字数要求)。
【1】Entering a study abroad program was a personal program for myself. College had not been fun up until that point. I was looking for excitement. After meeting a guy who loved to travel, he convinced me that studying abroad was one of the best decisions he had ever made and that I should try it. Immediately I visited my study abroad office and discovered many choices. I only spoke Spanish, but not fluently enough to feel comfortable in a program that was based in Spain or Mexico. This meant I needed a country that spoke English. Finally I chose the University of Central London.
【2】Many people hesitate before studying abroad because they think they__________. I went to college on loans(贷款), so a semester abroad would be no different. The additional expenses, such as food and travel, were the most expensive part of the trip. Any student travelling abroad received part of a grant donated to our school. This took almost $ 2,000 off the cost of my trip.
【3】Looking back on my experience years later, I am grateful that I took the chance and studied in London. I made a number of friends in London with locals, who are willing to help me anytime. I never felt unsafe because they would show me how to live in London, where to go and how to get anywhere I needed to go.
【4】My favorite memories in London is turn around my classwork. When studying abroad I took an English class that focused on British humor. During this class we watched British films and went to live performances. Before this class, I never understood British humor, and now I enjoy it more than American humor. My favorite class was art history. I cannot express to anyone how interesting it was to take art history in London.
【5】When people ask me if I would study abroad again, I exclaim, “yes!” You will never learn any lessons or information like you do when travelling abroad to a foreign country. As a person you will grow independent from everything. You will learn how to make friends and survive alone on your own. You will also learn to respect and understand other cultures.

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢)becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

D. giving up cooked and refined foods is a new lifestyle
