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(心理上) 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.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

2.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

A. are over-consumed                       B. lack basic nutrients

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

 

　　Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion(混淆) over possible links to the country of the same name, but Sudan officials say there is no connection whatever.?

Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.?

Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.?

Last week Sudan's Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye's name.?

Omaima Mahmoud Al Sharief, a press official at Sudan's Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.?

“We want to keep an eye on every detail and avoid any misunderstanding there,” she said. “Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship.”?

The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.?

“They asked us why the dye is named Sudan, however, we also do not know how it got the name,” she said. “People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out.”?

The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on.

Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes(条形码) or designs that cannot be seen.

“The papers can be faxed, scanned(扫描) and reprinted without hidden data disappearing,” New Scientist magazine said last week.

Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model.

The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture.

“Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image,” the magazine said.

Several images that can be hidden in a single picture are scanned into a computer which does the work.

The hidden images or fingerprints cannot be shown until the picture is scanned again.

The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture.

The magazine said that if he model is used for passport checkpoints the picture can be unscrambled(解码) to show the fingerprint or signature and checked against the person holding the passport.

The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier.

1. The new passport photos will probably contain all EXCEPT _____.

A．one’s picture	B．one’s fingerprint

Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK.

The shoes- named Square Eyes- contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter (发射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves(应得), based on the day's efforts.

The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design."

Once a child has used up their daily allowance gained through exercise, the television automatically (自动地) switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time.

Existing pedometers(计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations."

1.According to Swan, the purpose of her design project is to _____.

A．keep a record of the steps of the wearer.

B．deal with overweight among teenagers.

C．enable children to resist (抵制) the attraction of TV.

D．prevent children from being tricked by TV programs.

2.Which of the following is true of Square Eyes shoes?

A．They control a child's evening TV viewing time.

B．They determine a child's daily pocket money.

C．They have raised the hot issue of overweight.

D．They contain information of the receiver.

3.Compared with other similar products, the new design ___.

A．sends teenagers' health data(数据) to the receiver.

B．counts the wearer's steps through shaking.

C．records the sudden movement of the wearer.

D．make it difficult for lazy teenagers to cheat

4.Which of the following would be the best title for the text?

A．Smart Shoes Stop Childhood Overweight

B．Smart Shoes Guarantee More Exercise

C．Smart Shoes Measure Time of Exercise

D．Smart Shoes Decide on Television Time
