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 and physically.
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 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 lees 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. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products my not be nutritional,and the chemicals 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.

试题答案走丢了
It just may be the world’s most costly vacuum cleaner ( 吸尘器). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine.
CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there.
Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere (大气层) and burn up. But when they do not, it creates big problems.
Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine.
CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction (摩擦) with the air.
Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below.
1.Space junk is created when .
A. unused spacecraft hit each other
B. people in space throw away rubbish
C. a new spaceship is sent up
D. an old spaceship creates friction with the air
2.What’s the danger of space junk?
A. It will pollute space.
B. It will hurt people on the Earth.
C. It will hit a spaceship.
D. It will burn in the atmosphere.
3.Unwanted objects will fall back to the Earth when .
A. they are made to move slowly
B. they meet other objects in space
C. they are not used for years
D. they are near the atmosphere
4.The passage is most probably a .
A. science research paper B. science fiction story
C. newspaper ad D. science news report
