Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment (营养).The old saying “An apple

a day keeps the doctor away” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy.
But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins, so why waste money on them?
In the modern western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening,

In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence（证据）does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate m

ore food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.
Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.
Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:
The more the men ran, the more fat they lost.
The more they ran, the more they ate.
Thus, those who ran the most ate the most, yet lost

the greatest amount of body fat.

I’m fat. I’m too skinny. I’d be happy if I were taller, shorter, had curly hair, straight hair, a

smaller nose, bigger muscles, longer legs. Do any of these statements sound familiar? Do you often put yourself down? If so, you’re not alone. As a teen, you’re going through a ton of changes in your body. And as your body changes, so does your image (形象) of yourself. Lots of people have trouble getting used to it and this can affect their confidence.
Some people think they need to change how they look or act to feel good about themselves. But actually all you need to do is change the way you see your body and how you think about yourself.
The first thing to do is recognize that your body is your own, no matter what shape, size, or color it comes in. If you’re very worried about your weight or size, go to your doctor to check that things are OK. But it’s no one’s business but your own what your body is like—finally, you have to be happy with yourself.
Nex

t, find which aspects (方面) of your appearance you can change and which you can’t change and need to accept—like their height, for example, or their shoe size.
If there are things about yourself that you want to change and can do this by making goals for yourself. For example, if you want to get fit, make a pan to exercise every day and eat nutritious foods.
When you hear negative comments coming from within yourself, tell yourself to stop. Try building your confidence by listing three things in your day that really gave you pleasure.

Health officials issued a waring over common energy-saving l一ghtbulbs(灯泡) after research showed some types could potentially harm the skin and may even raise the risk of cancer.
A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) (紫外线) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics.
John O’Hagan, a scientist at the HPA’s centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light.
The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were equivalent to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn.
The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs.
小题1:The underlined word “equivalent” in paragraph 4 most probably means ______.

A．equal

B．vital

C．relevant

D．harmful

小题2:In order not to be harmed by the UV radiation from some lightbulbs, people should ______.

A．stop using eco-friendly lightbulbs at home

B．avoid using open lightbulbs for long close work

C．take care not to expose their skin to direct sunlight

D．urge the government to ban the use of lightbulbs

小题3:In the next part, the author would most probably further explain _____.

A．why people needn’t remove the lightbulbs from their homes

B．how researchers have planned to sort out the problem

C．how the government has responded to HPA’s discovery

D．how long people should work close to the open lightbulbs

小题4:We can learn from the passage that ____.

A．health officials issued a warning over common lightbulbs.

B．jewellery makers should avoid working with the eco-friendly bulbs for more than one hour

C．John O’Hagan did tests on the lightbulbs with some patients

D．people are advised to avoid using open lightbulbs for long close work

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer（模糊的） than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.
When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.
The image you create for yourself has rather strange proportions（部分）; certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.
Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.
If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes （中风）which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.
小题1:According to the passage the “felt” image the mirror image.

A．is precisely the same as	B．is as clear as
C．often differens from	D．is always much smaller than

小题2:Which the following staterants is NOT true?

A．The felt Image is much more important because it helps you locate new feelings.

B．When you are in bed with your eyes closed, it is not easy to imagine your image.

C．When you move, the “felt” image of yourself starts to become clearer.

D．The “felt” image is not so important as the mirror image.

小题3:If a man loses the ability to recognize his right side, .

A．he can’t locate the doctor’s touch on his left side

B．he can’t locate the doctor’s touch on his right side

C．he loses his sense of touch on the left side

D．he loses feeling on both sides

小题4:What is this passage mainly about?

A．Stroke victims’“felt” images	B．Stroke victims’ mirror images.
C．The importance of “felt” images	D．The importance of mirror images.

More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons．Exercise strengthens the heart muscle，reduces blood pressure and help to prevent muscles from changing into fat．Physical exercise is just as important for children．
Exercise and food affect growing speed in young lab animals．Baby mice start running as soon as they are big enough to use an exercise wheel in their cage．If they get extra food and run a lot，they will grow as much as 1.5 times bigger than normal．
The same differences in growing speed might be found between active and inactive children．Physical exercise helps active children grow faster than inactive children．One experiment shows that the brains of the mice that had enough exercise weighed about 3％more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise．
The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected．
The good effects of physical exercise are not limited to children and middle-aged people．Exercise continues to be an important part of our lives after we grow old．For example，people over 50 years old begin to lose calcium(钙) from their bones，which get weaker and can break easily．Physical exercise，however，helps to strengthen the bones and to prevent them from losing calcium．Of course，old people can take medicines to prevent themselves from suffering from losing calcium．But the medicines they take increase the chance of developing some kind of cancer(癌)．So physical exercise is a much safer treatment(治疗)．
