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 (潜能) of diet products that we 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
53．One psychological effect of diet products is that people tend to ______．
A．try out a variety of diet food B．hesitate before they enjoy diet foods
C．pay attention to their own eating habits D．watch their weight rather than their diet
54．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
55．Diet products indirectly harm people physically because such products _____
A．are over- consumed B．are short of chemicals
C．lack basic nutrients D．provide too much energy
56．Which of the following shows the structure of the passage?

Dogs are known for their sense of smell．They can find missing people and things like bombs and illegal drugs．Now a study suggests that the animal known as man’s best friend can even find bladder（膀胱）cancer．
Cancer cells are thought to produce chemicals with unusual odors（气味）．Researchers think dogs have the ability to smell these odors, even in very small amounts, in urine（尿）．The sense of smell in dogs is thousands of times better than in humans．
The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner．The man was later found to be skin cancer．Carolyn Willis led a team of researchers at Amersham Hospital in England．They trained different kinds of dogs for the experiment．The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people．Each dog was tested 8 times．In each test there were 7 samples for the dogs to smell．The dog should signal the one from a bladder cancer patient by lying down next to it．Two cocker dogs were correct 56 percent of the time．But the scientists reported an average success rate of 41 percent．The British Medical Journal published the research．In all, 36 bladder cancer patients and 108 other people took part．During training, all the dogs reportedly even identified（认出）a cancer in a person who had tested healthy before the study．Doctors found a growth on the person’s right kidney（肾）．Carolyn Willis says dogs could help scientists identify the combined chemicals produced by bladder cancer．That information could then be used to develop machines to test for the chemicals．The team also plans to use dogs to help identify markers for other kinds of cancer．
49．What’s the general idea of the text?
A．Dogs have a good sense of smell B．Dogs can help cure cancer
C．Dogs can smell cancer D．Dogs help perform experiments
50．According to the text, people who suffer bladder cancer_____

A．showed B．used C．proved D．preferred
52．What can we conclude from the last paragraph?
A．Dogs can only smell bladder cancer．
B．Dogs have a good knowledge of cancer．
C．Cancer doesn’t have any sign in the beginning．
D．Scientists might invent some equipment to test cancer．

When Toyota’s president, Akio Toyoda, apologized for the recalls that have harmed Toyota’s reputation, he talked not just about his company’s fate, but also his nation’s.
“I hope to return Toyota to profit and contribute to the revitalization of Japan,” he said.
Once a leading symbol of Japan’s rise to global economic might, Toyota has become one of the most obvious signs of its decline. And even before the recalls, Japan’s rivals(竞争对手) from South Korea and China had started overtaking Japan in key industries from semi－conductors to flat-panel televisions. And Toyota on Tuesday issued another damaging recall, this time of its popular Prius car.
“At this rate, Japan will sink into the sea,” said Masatomo Tanaka, a professor at the Institute of Technologists. “If Toyota is not healthy, then Japan is not healthy.”
Many economists and business leaders say they hope that Toyota’s trouble will be the wake – up call that Japan needs to understand that its reliance on manufacturing(制造业) and industrial exports, which served the country so well after World War II, is no longer wise.
Yukio Noguchi, a professor of finance at Waseda University in Tokyo, said Japan must finally step into a post - industrial, service-based economy — a painful shift that the United States and Great Britain underwent in the 1980s. Others said Japan should focus on high-end, high-profit products, like robots and fuel cells, rather than mass-produced goods subject to quality-control issues.
“Even Toyota can fail. Even Lexus, even Prius,” said Mr. Noguchi. “Our world-leading manufacturing industry may no longer world-leading. This has a strong impact on the national psyche.”
According to the Cabinet Office, manufacturing accounted for 22% of Japan’s entire economic output in 2008, down from 28% in 1990. however, manufacturing’s share of the economy still remains far above the level of 12% in the US. And few economists or journalists here advocate abrupt shifting. Rather, the feeling is that Japan needs to find a new balance by replacing its traditional industries with more information technology and software industries in which it is weak.
Yet this shift will be hard for Japan, where many policy makers and experts still seem to cling to the old model of heavy industries and consumer goods. If Japan can pull it off, it could serve as a model for other export – dependent Asian nations, which will also eventually face the same choice.
“I hope that Toyota will change our way of looking at our economy,” Mr Noguchi said. “We cannot survive if we continue to stick to the old type of industries.”
67．Since the Second World War, have been contributing much to Japan’s economy.
A．high – end and high – profit products like robots and fuel cells
B．manufacturing and industrial exports
C．information technology and software industries
D．industries from semi – conductors to panel – televisions
68．Which of the following statements is TRUE according to the passage above?
A．Few Japanese economists advocate a rapid shift into a service – based economy.
B．Most journalists in Japan advocate an abrupt change into a post – industrial economy.
C．Many economists hold that it is too early for Japan to shift into a service – based economy.
D．No Japanese reporters think it high time for Japan to step into a post – industrial economy.
69．The underlined part “cling to” probably means in the passage.
A．hold on to B．keep up with C．turn to D．pick up
70．From the passage we know the way out for Japan to get itself free from its decline consists in
.
A．keeping up its reliance on manufacturing
B．continuing to focus on its industrial export
C．speeding up its shift into a post – industrial economy
D．increasing its manufacturing

An analysis by Mount Sinai researchers of over eight years of dietary data from more than 400,000 people has found that the relationship between high consumption of fruits and vegetables and a reduced risk of cancer is not as strong as commonly thought. The study is published online April 6, 2010 in the Journal of the National Cancer Institute. It is widely believed that a diet rich in fruits and vegetables can reduce the risk of cancer. In 1990, the WHO recommended eating five servings of fruits and vegetables a day to prevent cancer and other diseases. However, although many studies have been conducted since then, none have been able to confirm an association between fruit and vegetable intake and cancer resistance.
Paolo Boffetta, MD, MPH, lead author of the study and Deputy Director of The Tisch Cancer Institute at Mount Sinai School of Medicine, and colleagues analyzed data from the EPIC study to evaluate relationships between cancer risk and intake of total fruit and vegetables combined.
The EPIC followers, which are ongoing and organized by professor Elio Riboli at Imperial College in London, included 142,605 men and 335,873 women surveyed between 1992 and 2000 from 10 Western European countries. Detailed information on their dietary habits and lifestyle differences was obtained. After 8.7 years of follow – up, more than 30,000 of the study's participants were diagnosed with cancer.
Dr. Boffetta and colleagues found a small but significant opposite relationship between high intake of fruits and vegetables and overall cancer risk. In this population, an increase of 200 grams a day of fruits and vegetables resulted in a reduction of about 3 percent of cancer risk. Vegetable consumption by itself also afforded a modest benefit but was restricted to women. Heavy drinkers who ate many fruits and vegetables had a somewhat reduced risk, but only for cancers caused by smoking and alcohol.
"The bottom line here is that, yes, we did find a protective effect of fruit and vegetable intake against cancer, but it is a smaller connection than previously thought," said Dr. Boffetta. "Any cancer protective effect of these foods is likely to be modest, at best.
"However, eating fruits and vegetables is beneficial for health in general and the results of this study do not justify changing current recommendations aiming at increasing intake of these foods," said Dr. Boffetta.
63．A new study shows that .
A．eating fruits and vegetables is beneficial to health
B．a diet rich in fruits and vegetables can reduce the risk of cancer
C．eating five servings of fruits and vegetables a day can prevent cancer and other diseases
D．the association between fruit and vegetable intake and cancer resistance is small
64．Before this study, people would believe that.
A．high intake of fruits and vegetables can prevent cancer and other diseases
B．heavy drinkers have the slightest chance of cancer
C．the WHO’s recommendations were modest
D．the WHO’s recommendations aim at increasing intake of fruits and vegetables
65．The population who took part in this study amounted to .
A．142,605 B．335,873 C．more than 400,000 D．30,000
66．From this study, we can infer that .
A．the intake of fruits and vegetables will be no longer necessary
B．the connection between fruits and vegetables intakes and cancer resistance is smaller than originally thought
C．taking in fruits and vegetables will still be appreciated in spite of the new discovery
D．any cancer protective effect of these foods is likely to be modest
