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（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.From Paragraph 1, we learn that _________.
A. diet products fail to bring out people's potential
B. people have difficulty in choosing diet products

2.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
3.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

Let’s face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.
Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn’t drink diet sodas. ＂What we saw was that the more diet sodas a person drank, the more weight they were likely to gain,＂ said Sharon Fowler.
The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.
While the findings are surprising, they also offer some explanations.
Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don’t lose weight at all. "We weren’t seeing weight loss necessarily, and that was confusing to us,＂ said Rogers.
So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over-compensate(补偿) for the missing calories.
A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. ＂Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky,＂ said Helen P. Hazuda, professor at the University of Texas’s school of medicine. ＂They may be free of calories, but not of consequences.＂
1.People drink diet sodas to ____________.
A. enjoy its taste B. achieve weight loss
C. stay in fashion D. gain more energy
2.The new study suggests that drinking diet sodas ____________.
A. causes people to become heavier
B. helps people to be healthier
C. makes people much thinner
D. offers people more calories
3.We can learn from the passage that ____________.
A. regular sodas make people lose more weight
B. diet soda drinkers tend to eat more food
C. diet sodas do help reduce calories
D. most blood diseases come from diet sodas
4.The underlined word “They” in the last paragraph probably refers to “_________”.
A. sweeteners B. diet soda drinkers and sweetener takers
C. sodas D. diet sodas and artificial sweeteners

Is Your Diet Destroying the Environment?
A vegetarian diet is often praised for its health benefits. Studies have shown that vegetarians usually have lower levels of heart disease and a lower risk of diabetes than people who eat meat. What most people are less aware of, however, are the effects that a vegetarian diet can have on the environment.
Researchers from the Union of Concerned Scientists in the US recently studied how consumer behavior affects the environment. The study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicle.
Then, how can eating meat have a negative effect on the environment? For a start, all farm animals such as cows, pigs, and sheep give off methane (沼气) gas by expelling (排出) wind from their bodies. One cow can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide. Many environmental experts now believe that it is more responsible for global warming than carbon dioxide. It is estimated that 25% of all methane released into the atmosphere comes from farm animals.
Another way that meat production affects the environment is through the use of water and land. 2,500 gallons of water are needed to produce one pound of beef, whereas 20 gallons of water are needed to produce one pound of wheat. One acre of farmland used for crop production can produce 40,000 pounds of potatoes, 30,000 pounds of carrots, or 50,000 pounds of tomatoes.
Many people now see the benefits of switching to a vegetarian diet, not just for health reasons, but also because it plays a vital role in protecting the environment. However, some nutritionists advise against switching to a totally strict vegetarian, or vegan diet. They believe a vegan diet, which excludes all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.
Today, many people know it’s important to take better care of their bodies and to use the earth’s resources more efficiently. As this understanding spreads, more people may realize that to help the environment and for the human race to survive, more of us will need to become vegetarians.
1.The underlined word “it” in Para.3 refers to ___________.
A.methane gas B.carbon dioxide
C.expelling wind D.greenhouse gas
2.Many figures are used in Para.4 to show ___________.
A.growing tomatoes has the highest production
B.crop production is better than meat production
C.meat production consumes too much water and land
D.farm animals are the main producer of the methane gas
3.What message does the passage want to convey?
A.Our diet is destroying the surroundings.
B.Raising farm animals affects the environment.
C.A vegetarian diet helps to protect the environment.
D.More and more people are becoming strict vegetarians.
