An allergy is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen (花粉), which is usually produced by trees in the spring, grasses in the summer and weeds in the fall, as part of their reproductive process.
Other causes include organisms, chemicals, plants and dead skin particles from dogs and cats can also cause allergic reactions. So can insect stings and some food.
The most common kind of allergic reactions is itchy (癢的) , watery eyes and a blocked or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-threatening, for example, when breathing passages become blocked.
It is not always easy to avoid allergies. Drugs may offer an effective treatment. Another treatment used in some cases is called immunotherapy. A patient is injected with small amounts of the allergy-causing substance. The idea is that larger and larger amounts are given over time until the patient develops resistance in his body.
In the United States, experts estimate that up to 8% of young children have food allergies. Every year these allergies cause about 30,000 cases with severe reactions that require immediate treatment. It can result in breathing trouble and in some cases death. It is said that about 100 to 200 people will die. It is said that most of the reactions are caused by peanuts and tree nuts like walnuts.
People can also be allergic to medicines. The American Academy of Allergy, Asthma and Immunology says about 10％ of bad reactions to commonly used medicines are allergic. In other words, a person’s immune system overreacts and produces an allergic reaction. The most common reactions include skin rashes, itching, breathing problems and swelling in areas such as the face.

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.
The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.
So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.
There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （oppositely） affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.
So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不動的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?
【小題1】Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.
| A．beauty should be overweight |
| B．a(chǎn) fat man is usually a cheerful character |
| C．fatness was considered something good at one time |
| D．fatness leads to an increased risk of disease |
| A．go on a diet | B．do regular physical activity |
| C．give up smoking | D．go to the gym |
| A．people who help you do exercise | B．places where you can do exercise |
| C．a(chǎn) kind of shoes | D．a(chǎn) form of vehicles |
| A．a(chǎn)n increased risk of diseases | B．a(chǎn) happier life |
| C．a(chǎn) cheerful character | D．a(chǎn) beauty |
| A．how to keep fit and avoid fatness. | B．increased risks for overweight people. |

In today's fast-paced (快節(jié)奏) society, few people take time to enjoy the midday meal．Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch．
The development of technology hasn't done our eating habits much good either．We are constantly distracted by e-mail, social media, and 24 - hour news．Even when we do sit down for lunch, we are more connected to our hand - held electronic devices．
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break．These laws give employees the right to take a break during a long work shift, but it's up to them whether they do so or not．
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch．This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective（認(rèn)識）． A break from work allows us to think strategically and outside the box．It also puts our daily tasks into a broader context（背景）．
What we eat at lunch is also important．In Partnoy' s opinion, a fast food lunch is more harmful than not having lunch at all． And it's not just about calories and unhealthy food．Recent studies show that fast food also has negative effects on how we think．
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain．
Despite these benefits, some employees might still be unwilling to take time off for lunch．Partnoy's suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal．
【小題1】What does the underlined phrase "skip lunch" mean in the first paragraph?
| A．have a quick lunch | B．don't have lunch |
| C．work while having lunch | D．take a lunch break |
| A．Modern technology results in good diet habits． |
| B．Electronic devices make our life comfortable． |
| C．Many people are too busy to have a good lunch． |
| D．Laws have passed to make workers have lunch． |
| A．a(chǎn)re time for the workers to relax their mind |
| B．make the employees work longer hours |
| C．a(chǎn)re for employees to have a quick lunch |
| D．make the workers eat a proper lunch at home |
| A．saves a lot of time for a rest |
| B．a(chǎn)ffects people's way of thinking |
| C．is better than having no lunch |
| D．makes workers sit down and think |
| A．To warn us not to eat fast food． |
| B．To introduce Frank Partnoy's opinion． |
| C．To encourage us to work more efficiently． |
| D．To show the importance of a proper lunch． |

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism (新陳代謝) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious（惡性的）circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
【小題1】What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．a(chǎn)re difficult to digest |

Was the London Olympics a success? Many people hold different opinions. However one thing is certain, London could win a gold medal for hosting the “greenest” Games ever, BBC News reported.
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste. and transport. But things had to be different in London because seven years ago it bid for the Olympics through the concept of “a One Planet Olympics”.
What is most impressive is that London used the construction of the Olympic Park as an opportunity to clean up polluted areas — 2 million tons of contaminated (被污染的) soil were removed and 200 old factory buildings, were torn down, according to sustainablebusiness.com. But that’s not all —. 99 percent of the debris (廢瓦礫) were reused to build the Olympic Park. For example, part of the Olympic Stadium’s roof is made from 2,500 tons of steel tubes recycled from old gas pipelines.
As well as using recycled materials, all venues were built with green building techniques. The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed. Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent, according to sustainablebusiness.com.
The effort that London made to deal with waste also deserves praise. Water used for drinking and watering plants was from collected rainwater or recycled wastewater. In this way. about 30-40 percent less water was used in total. Waste food packages were either recycled or processed and turned into renewable energy.
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport. For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions.
The clean anti-doping (反興奮劑) result also added to the greenness of the Games. The International Olympics Committee (IOC) said that the devices used this time were the most accurate and advanced. Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games.
【小題1】To make the Olympic Park green, London _______.
| A．recycled 2 million tons of contaminated soil |
| B．removed 99 percent of the debris from the city |
| C．built the Olympic Stadium mostly with recycled materials |
| D．a(chǎn)pplied green building techniques to the construction work |
| A．increased as much as possible |
| B．reduced as much as possible |
| C．made good use of |
| D．took little notice |
| A．The London Olympics cost less than the other Olympics ever held. |
| B．London has possessed the most advanced techniques to deal with waste. |
| C．Public transport is made good use of in London during the Olympic games. |
| D．The anti-doping result in the London Olympics turned out to be dissatisfactory. |

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
While such vigilant(警覺的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(預(yù)期壽命).
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
【小題1】Why do doctors recommend routine cancer screening for elderly people?
| A．It is believed to contribute to long life. |
| B．It is part of their health care package. |
| C．The elderly are more sensitive about their health. |
| D．The elderly are in greater danger of tumor growth. |
| A．It adds too much to their medical bills. |
| B．It helps increase their life expectancy. |
| C．They are doubtful about necessity. |
| D．They think it does more than good. |
| A．It applies to women over 50. |
| B．It is a must for adult women. |
| C．It is optional for young women. |
| D．It doesn’t apply to women over 74. |
| A．They want to protect themselves against medical disputes. |
| B．They want to take advantage of the medical care system. |
| C．They want data for medical research. |
| D．They want their patients to suffer less. |
| A．The more, the better. |
| B．Prevention is better than cure. |
| C．Better early than late. |
| D．Better care, longer life. |

“Image is everything.” An entire industry has been built upon the concept that image is everything, but an appealing image isn’t enough when there’s no substance behind it.
First of all, one should consider how important image is in selling products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. But if the product or service doesn’t live up to it, customers will be very dissatisfied. The recent scandal (丑聞) about the Arthur Andersen accounting firm showed that behind that image, it had unfair business practices under the table. Despite the previous positive image, the firm is being accused of criminal actions. Although the image had been nearly perfect, the reality behind the image has led to its downfall.
Similarly, personal consultants(顧問) can build up a very positive public image for politicians and movie stars in the view of the general commons. But once again, history is filled with examples of both that fell from grace (體面) like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind it, failure is close.
To conclude, it’s clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation(等式). What lies behind that image is every bit as important as the image itself — the person or product must live up to that image or there’s little chance for long-term success.
【小題1】The downfall of the Arthur Andersen accounting firm is due to ______.
| A．its dishonesty in business |
| B．its bad management |
| C．its previous images |
| D．its poor service |
| A．their images were not well built up |
| B．they failed to live up to their images |
| C．they felt much pressure from the public |
| D．they paid little attention to fame and fortune |
| A．image is the basis of everything |
| B．truth and image are equally important |
| C．truth goes hand in hand with image |
| D．image holds the key to success |

科目：高中英語 來源： 題型：閱讀理解
People have wondered for a long time how their personalities and behavior are formed. It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are of course extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behavior. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between proponents of each theory. The controversy is often conveniently referred to as “nature and nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme，this theory states that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts(本能)．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic. They state that, like machines, humans respond to environmental stimuli (刺激) as the basis of their behavior.
Socially and politically, the consequences of these two theories are far-reaching. In the US，for example, blacks often score below whites on standardized intelligence tests. This leads some “nature” proponents to conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes and that the controversy will continue for a long time is certain.
【小題1】This passage is mainly concerned with ________.
| A．relation between personality and behavior |
| B．relation between behavior and environment |
| C．different accounts of patterns of human behavior |
| D．different theories of the formation of human behavior |
| A．creators | B．a(chǎn)dvisors | C．a(chǎn)dvocates | D．judges |
| A．the considerable influence of the two theories |
| B．differences between the blacks and whites |
| C．racial discrimination in the United States |
| D．different responds to intelligence tests |
| A．To call our attention to the changes of human behavior. |
| B．To urge scientists to do more research in social science. |
| C．To give us a detailed explanation of human behavior. |
| D．To present an argument in the field of social science. |
