In recent years, temperatures in the polar areas are rising faster than anywhere else on Earth. As a result, the ice and the snow are melting at record-setting rates. One result is that sea levels are rising around the world, putting animals and people at risk.

A sheet of ice acts like a huge mirror, reflecting the sun’s energy. But ocean water, which is darker than ice, absorbs a lot of it. This causes the ocean to warm, which in turn speeds up ice melting and which leads to even more open waters. The cycle continues until all the ice is gone.

“As the ice melts, water flows into the oceans, making them less salty. That, along with warmer water temperatures, can harm the creatures that live in, under, and near the ice,” says zoologist Michael Stoddard. “Cold-adapted animals — including polar bears, foxes, hares, and seals — also need ice for travel and survival.”

“Most species of fish, sea spiders, and many other animals and plants that live in the waters of Antarctica don’t live anywhere else,” Stoddard says. “Many of them have special proteins in their bodies keeping them from freezing to death and have other adaptation to the cold that has yet to be explored.”

Therefore, experts are urging us to reconsider the way we live. The fuels that we burn in cars, power stations, and factories are largely to blame for the carbon dioxide and other greenhouse gases that are trapping overmuch heat in our atmosphere. If we can produce fewer of these gases, we can help save the polar ice. “Even small things would make a difference, if everyone did them.” Michael Stoddard says, “That’s what we have to figure out in the near future to help save the polar ice and thus protect the oceans and us.”

B. some of the cold-adapted animals mainly feed on ice

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（身体上）.

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 are fed up with diet products

C. people have difficulty in choosing diet products

D. diet products are misleading people

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

A. hesitate before they enjoy diet foods

B. pay attention to their own eating habits

C. watch their weight rather than their diet

D. try out a variety of diet foods

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

A. losing weight is effortless

B. diet products bring no pain

C. it costs a lot to lose weight

D. diet products are free from calories

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

A. lack basic nutrients B. are over-consumed

C. are short of chemicals D. provide too much energy
