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 brains 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. 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 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 and physical harm that comes from using them.

1. From Paragraph 1, we learn that __________.

   A. diet products are misleading people

B. people have difficulty in choosing diet products

   C. diet products fail to bring out people’s possibility

D. people are fed up with diet products

2.One psychological effect of diet products is that people tend to ______.

   A. try out a variety of diet foods   B. watch their weight rather than their diet

C. pay attention to their own eating habits            D. hesitate before they enjoy diet foods

3. In Paragraph 3, “gain comes without pain” probably means ________.

   A. diet products bring no pain       B. it costs a lot to lose weight

   C. losing weight is effortless       D. diet products are free from calories

4. Diet products indirectly harm people physically because such products ______.

   A. are over-consumed                 B. provide too much energy

C. are short of chemicals            D. lack basic nutrients

Farmer John and Farmer Bob were neighbours. For more than 30 years, they had been getting along very well.

The carpenter said, “I think I know what to do, sir, and I’ll be able to do a job that pleases you.”

Farmer John helped the carpenter get the materials ready and then he was off for the day.
