Tom was a clever boy, but his parents were poor, so he had to work in his spare time and during his holidays to pay for his education. In spite of this, he managed to get to the university, but it was so expensive to study there that during the holiday he found it necessary to get two jobs at the same time so as to make enough money to pay for his studies.

One summer he managed to get a job in a butcher's shop(肉店)during the day-time, and another in a hospital at night. In the shop, he learnt to cut meat quite nicely, so the butcher often left him to do all the serving while he went to the back room to do the accounts(账目). In the hospital, on the other hand, he was, of course, allowed to do the simplest jobs, like helping to lift people and to carry them from one part of the hospital to another. Both at the butcher's shop and at the hospital, Tom had to wear white clothes.

One evening at the hospital, Tom had to carry a woman from her bed to the place where she was to have an operation. The woman was already feeling frightened at the thought of the operation before he came to get her, but when she saw Tom, that finished her. "No! No!" she cried．"Not my butcher! I won't be operated on by my butcher!" and fainted away(昏厥).

    Soda is refreshing and delicious, but it is not part of a healthy, balanced diet. Most sodas are packed with sugar. In fact, a can of soda can be hiding up to 10 teaspoons of sugar! The sugar does make soft drinks delicious, but definitely not nutritious. Too much sugar in a person's diet can lead to diabetes (糖尿病), heart disease, and tooth problems. One of the biggest sugary soda problems is that drinking much can lead to weight gain and even obesity.

    There are diet options available for almost every kind of pop (汽水), which means that you don't have to drink all that sugar in order to enjoy a can of soda. Many studies have been done on whether or not aspartame (甜味剂), the sugar substitute in diet soda, is bad for you. Up to now, there are still conflicting opinions on this issue. The European Food Safety Authority recently concluded that aspartame is safe for most people, even in fairly large amounts. Aspartame still might not be good for you, though. Studies have shown that people who drink diet sodas may actually gain more weight than those who drink regular soda, perhaps because, strangely enough, drinks loaded with fake sugar may actually make you want to eat more.

    Maybe you've decided it's time to cut down on your soda drinking, but what should you drink instead? Water is absolutely the healthiest thing that you can drink. Your body needs water to stay hydrated (水合物) and function properly, and water contains no calories or fat. Drinking fruit juice occasionally is not a bad thing, but you should be careful what juice and how much juice you're drinking. Fruit juices can contain almost as much sugar as pop!

    As with most things to do with your health, moderation is really at the base of any healthy diet. You can totally drink soda, even the sugary kind just, make sure you're not drinking too much!

    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 programmer of electrification. Thanks to the programmer, 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 "worldwide 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.

    Can We Stop Food Longing Through Imaginary Eating?

    Are you fighting an urge to reach for chocolate? Then, let it melt in your mind, not in your mouth. According to the recent research, imagining eating a specific food reduces your interest in that food, so you eat less of it.

    This reaction to repeated exposure to food—being less interested in something because you've experienced it too much—is called habituation.

    The research is the first to show that habituation can occur through the power of the mind. "If you just think about the food itself—how it tastes and smells—that will increase your appetite," said Carey More wedge, a well-known psychologist. "It might be better to force yourself to repeatedly think about chewing and swallowing the food in order to reduce your longing.Visualizing yourself eating chocolate wouldn't prevent you from eating lots of cheese," he added.

    More wedge conducted an interesting experiment. 51 subjects were divided into three groups. One group was asked to imagine putting 30 coins into a laundry machine and then eating three chocolates.Another group was asked to imagine putting three coins into a laundry machine and then eating 30 chocolates. Lastly, a control group imagined just putting 33 coins into the machine—with no chocolates.When they said they had finished, these were taken away and weighed. The results showed the group that had imagined eating 30 chocolates each ate fewer of the chocolates than the other groups.

    Physical signals—that full stomach feeling—are only part of what tells us we've finished a meal. The research suggests that psychological effects, such as habituation, also influence how much a person eats. It may lead to new behavioral techniques for people looking to eat more healthily, or have control over other habits.

A. What's more, this only works with the specific food you've imagined.

B. People were advised to try different methods to perform the experiment.

C. For example, a tenth bite is desired less than the first bite, according to the study.

D. All of them then ate freely from bowls containing the same amount of chocolate each.

E. It meant those who repeatedly imagined eating would concern about some specific food.

F. This requires the same motor skills as eating small chocolates from a packet, the study says.

G. This study is part of the research looking into what makes us eat more than we actually need.

    In primary school, I 1 felt different or alone just for in a wheelchair. My life flowed like a river. I took part in lots of 2, like dance and music. I even went onstage in my wheelchair and performed dances and won prizes.

    Then came the 3 for surgery (外科手术) that might help me walk. 4 I went into the operating room, I was hopeful and shut my eyes, and the world 5 around me. After my surgery, I was in so much pain that stepped into state of 6, shutting out everybody. I even 7 having the surgery and nearly gave up on my lifelong 8— walking.

    My life began to turn back around when I went to an inpatient rehabilitation center (住院康复中心), along with my mom. At first, I didn't 9 staying there, with all kinds of therapies (疗法) and doctor visits. There was so much I couldn't do, like playing at the nearby playground when my dad and brother 10. What was worse, it was 11 to make friends.

    As I felt better, things began to get 12. I made a good friend, and the playground became a harbor for my 13. I could paint pictures with my mind and bring characters to life. I was 14 puzzle pieces of myself and putting them back together.

    Lately, I've been able to stand with help for five minutes straight. I feel 15 again and am dreaming big. I want to 16 companies to create role models for disabled kids to look up to — like maybe a disabled hero in a movie. I've also 17 the Just Say Hi campaign, which encourages everyone not to be afraid to accept and greet people who have a 18.

    This journey has changed my life. It's made me brave and 19. My message is: stay strong, stay determined, and don't ever think your 20 are out of reach.

    (Make) new friends means putting yourself out on a limb(孤立无援) and asking others not only to accept you, but to like you and want to be around you as well. (unfortunate), there is no magical solution to this part of process, so if you want to make friends, take a deep breath and jump right in.

    first step to making friends is figuring out what is holding you back. A lot of times people are interested in making new friends don't know why they don't have them already. They can't see that . (they) own working against them.

    Once you can identify what is keeping you from making new friends, you need to work through these concerns. This can be painful because you will need to put yourself outside of your comfort zones to see any real (difference) .

The next step is to shine in these social setting so that others will leave with a positive (impress). If you find social situations hard, just rely a few simple rules.

    When you feel (confidence) that you've made some great new friends, get out there and celebrate it with them! No matter what you decide (do), the important thing is to celebrate your new friends and hopefully continue cultivating (培养) more.
