How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的)tests，for everything from baldness to breast cancer，and the list is growing．Question is do you really want to know what might eventually kill you? For instance，Nobel Prize-winning scientist James Watson，one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your 1ife as you wait for that disease to hit you．It could really mess you up．”Said Dr．Robert Green，a Harvard geneticist.
“Every ache and pain，”Smith suggested，could be understood as“the beginning of the e nd．”“That’s right．If you ever worried you were at risk for Alzheimer's disease，then every time you can’t find your car in the parking lot，you think the disease has started．”
Dr．Green has been thinking about this issue for years．He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s．It was thought that people who got bad news would，for lack of a better medical term，freak out．But Green and his team found that there was “no significant difference”between how people handled good news and possibly the worst news of their lives．In fact，most people think they can handle it．People who ask for the information usually can handle the information，good or bad，said Green．

Cutting global warming pollution would not only make the planet healthier, it would make people healthier too, new research suggested.
Cutting carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies released Wednesday and published in a special issue of The Lancet, a British medical journal.
"Relying on fossil fuels leads to unhealthy lifestyles, increasing our chances of getting sick and in some cases takes years from our lives," US Health and Human Services Secretary Kathleen Sebelius said in a telecast briefing from her home state of Kansas. "As greenhouse gas emissions go down, so do deaths from cardiovascular（心血管） and respiratory（呼吸道） diseases. This is not a small effect."
Instead of looking at the health ills caused by future global warming, as past studies have done, this research looks at the immediate benefits of doing something about the problem, said Linda Birnbaum, director of the US National Institute of Environmental Health Sciences.
Some possible benefits seemed highly speculative, the researchers conceded, based on people driving less and walking and cycling more. Other proposals studied were more concrete and achievable, such as reducing cook stoves that burn dung（粪便）, charcoal and other polluting fuels in the developing world.
And cutting carbon dioxide emissions also makes the air cleaner, reducing lung damage for millions of people, doctors said.
"Here are ways you can attack major health problems at the same time as dealing with climate change," said lead author Dr. Paul Wilkinson, an environmental epidemiologist at the London School of Hygiene and Tropical Medicine.
Wilkinson said the individual studies came up with numbers of premature deaths prevented or extra years of life added for certain places.
For example, switching to low-polluting cars in London and Delhi, India, would save 160 lost years of life in London and nearly 1,700 in Delhi for every million residents, one study found. But if people also drove less and walked or biked more, those extra saved years would soar to more than 7,300 years in London and 12,500 years in Delhi because of less heart disease.
【小题1】What does the passage mainly talk about? _______.
| A．How can people live longer? |
| B．Cutting carbon dioxide emissions saves lives. |
| C．Global warming threatens people’s lives. |
| D．People should stop relying on fossil fuels. |
| A．it focuses on the immediate benefits of cutting carbon dioxide emissions |
| B．it studies the bad effects arising from future global warming |
| C．it is believed by more people |
| D．it mainly targets at developing countries |
| A．sometimes it takes years to see the bad effects caused by consuming fossil fuels |
| B．without greenhouse gas emissions, people would not die of cardiovascular and respiratory diseases |
| C．the main reason why people get sick is that they rely on fossil fuels |
| D．deaths from cardiovascular and respiratory diseases are closely related to greenhouse gas emissions |
| A．Driving less |
| B．Walking and cycling as much as possible. |
| C．Stopping using fossil fuels |
| D．Reducing the use of polluting fuels to cook. |
| A．London and Delhi have already benefited from reducing greenhouse gas emissions |
| B．switching to low-polluting cars would save 160 lives in London each year |
| C．walking and biking instead of driving will reduce the chance of heart disease |
| D．attacking health problems and dealing with climate change are contradictory |

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 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 （新陈代谢）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 circle in its tracks, people need to consume food and supplements that will neutralize 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.
【小题1】It can be inferred from Para. 2 that __________.
| A．foods with natural enzymes help people keep fit |
| B．we’d better be cautious about raw and whole foods |
| C．it is essential for people to protect their vital organs |
| D．giving up cooked and refined foods is a new lifestyle |
| A．destroy body’s cells | B．may lead to obesity |
| C．are difficult to digest | D．stop body’s metabolism |
| A．To warn people of the problem of obesity. |
| B．To advocate eating more raw and whole foods. |
| C．To inform people of the harm of processed foods. |
| D．To tell the differences between raw and processed foods. |
| A．Different causes of acid accumulation. |
| B．Correct ways to cook raw foods. |
| C．Suitable types of raw and whole foods. |
| D．Active approaches to avoid acid. |

Millions of Americans return from long-distance trips by air, but their luggage doesn’t always come home with them. Airline identification tags（标签） can come loose, and the bags go who-knows-where. And passengers leave all kinds of things on planes.
The airlines collect the items and, for 90 days, attempt to find their owners. They don’t keep them, since they’re not in the warehouse business. And by law, they cannot sell the bags, because the airlines might be tempted to deliberately misplace luggage.
So once insurance companies have paid for lost bags and their contents, and they no longer belong to passengers, a unique store in the little town of Scottsboro, Alabama, buys them. The “Unclaimed Baggage Center,” is so popular that the building, which is set up like a department store, is the number-one tourist attraction in all of Alabama. More than one million visitors stop in each year and take one of the store’s shopping carts on a hunt for treasures.
Each day, clerks bring out 7,000 new items, and veteran（老练的）shoppers rush to paw over them. You can find everything from precious jewels to hockey sticks, best-selling novels, leather jackets, tape recorders, surfboards, even half -used tubes of toothpaste.
The store’s own laundry washes or cleans all the clothes found in luggage, then sells them. The Unclaimed Baggage Center has found guns, illegal drugs and even a live rattlesnake.
The store has a little museum where some of its most unusual acquisitions（获得物） have been preserved. They include highland bagpipes, a burial mask from an Egyptian pharaoh's tomb, and a medieval suit of armor.
Statistics indicate that less than one-half of one percent of luggage checked on U.S. carriers is permanently lost and available to the store.
【小题1】 Paragraph1 shows that many passengers lose their luggage because______.
| A．they are forgetful |
| B．they are in a hurry |
| C．there is no lost and found office in many airports |
| D．the owners of some luggage can’t be identified |
| A．they have to find the owners |
| B．they are likely to make a profit on the bags on purpose |
| C．some bags are expensive |
| D．they have to keep the bags as long as possible |
| A．there's a large variety of goods. |
| B．all thethings there are very cheap. |
| C．visitors may purchase something undervalued. |
| D．Visitors will enjoy some amusing activities there. |
| A．A little museum will keep all the precious unclaimed baggage. |
| B．The percentage of passengers who lose their baggage for ever is small. |
| C．The things in the Unclaimed Baggage Center are articles for daily use. |
| D．People are not allowed to buy the illegal things in the store. |
| A．To introduce how the unclaimed baggage in the airports is handled in America. |
| B．To introduce an attractive place to tourists. |
| C．To remind passengers of taking care of their baggage. |
| D．To advise the airlines to find the owners of the unclaimed baggage. |

Everyone looks forward to progress, whether in one’s personal life or in the general society. Progress indicates a person’s ability to change the way he is living at the moment. Progress must lead a better way of doing things. All these, however, remains true only in so far as people want to accept technology and move forward by finding new and more efficient ways of doing things.
However, at the back of the minds of many people, especially those who missed the “good old days”, efficiency comes with a price. When communication becomes efficient, people are able to contact one another no matter where they are and at whatever time they wish to. The click of a button allows people miles apart to talk or to see each other without even leaving their homes. With the communication gadgets, such as mobile phones and ipads, people often do not take the effect to visit one another personally. A personal visit carries with it the additional feature of having to be in the person’s presence for as long as the visit lasts. We cannot unnecessarily excuse our selves or turn the other person off.
With efficiency also comes mass production. Such is the nature of factories and the success of industrialization today. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when making these products. For example, many handcrafts(手工艺品) are now produced in a factory. Although this means that supply is better able to increase demand, now that the supply is quick and efficient, the demand might fall because mass production lowers the quality of the handicraft and it is difficult to find unique designs on each item.
Nevertheless, we must not commit the mistake of analyzing progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.
It is people’s attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people’s attitude. The worst effects of progress will fall on those who are unable to rethink their attitudes and views of society. When we accept progress and adapt it to suit our needs, a new “past” is created.
【小题1】According to Paragraph 1, progress can benefit people when they are willing to _______.
| A．live a better life |
| B．look for better methods |
| C．change ways of living |
| D．accept technology and advance steadily |
| A．tools | B．messages | C．barriers | D．skills |
| A．describing a process | B．using examples |
| C．following time order | D．making classification |
| A．lack great accuracy | B．lack the personal touch |
| C．are of high value | D．are quite welcome |
| A．It can destroy old traditions. |
| B．It can lead to social progress. |
| C．It can be used to correct mistakes. |
| D．It can be used to preserve old products. |
| A．Progress can suit the needs of daily life. |
| B．People review the past with great regret. |
| C．Technology should be introduced in a fixed way. |
| D．People’s attitude decides the use of technology. |

China is a land of bicycles.At least it was back in 1992 when I traveled the country.Back then everyone seemed to be riding a bicycle.Millions of them, all black.Cars were rare.Yet since my arrival in Beijing last year.I've found the opposite is true.There are millions of cars.However, people still use their bicycles to get around.For many, it's the easiest and cheapest way to travel today.Bicycles also come in different colors—silver, green, red, blue, yellow, whatever you want.
It's fun watching people biking.They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks(人行道)．Bicycles allow people the freedom to move about that cars just can't provide.
Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle.Great weather accompanied my great buy.I immediately jumped up on my bicycle seat and started home.

A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.
By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation（诱惑）early on were more likely to be lonely, easily frustrated and inflexible.
Actually, the ability to delay reward is a sign of emotional intelligence which doesn’t show up on an IQ test.
The hardware of the brain and the software of the mind have long been scientists’ concerns. But brain theory can’t explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul.
Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people’s success, brain ability as measured by IQ may actually matter less than the qualities of mind once thought of as “character”.
EQ is not the opposite(相反) of IQ. What researchers have been trying to understand is how they work together; how one’s ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients(要素) for success, researchers now generally agree that IQ makes up about 20%; the rest depends on everything from social class to luck.
While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.
【小题1】The experiment with the four-year-olds makes it clear that .
| A．the age of 4 is a proper time for scientific experiment |
| B．emotional intelligence won’t show up until adolescence |
| C．the ability of self-control plays a role in personal success |
| D．candy can be used to measure a person’s emotional intelligence |
| A．kind | B．floating | C．excited | D．cheerful |
| A．To amuse both the children and readers. |
| B．To prove the scientist’s wisdom. |
| C．To introduce the topic of the text. |
| D．To show us how to do an IQ test. |
| A．Information about famous people with high EQ. |
| B．Examples showing the opposite voice about EQ. |
| C．Some reasons why EQ is a relatively new field. |
| D．Strong demand for basic emotional education. |

They like using the Internet. They have lots of pocket money to spend. And they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy－games, CDs and clothing－are easily sold on the Web.
But paying online is a troublesome business for consumers who are too young to own credit cards. Most have to use a parent’s card. They want a facility that allows them to spend money.
That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate online sales.
In general, teenagers spend huge amounts: $153bn (billion) in the US last year and ￡20bn annually in the UK. Most teenagers have access to the Internet at home or at school－88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online－mainly CDs and books.
In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing them to spend on the high street. They are more likely to ask “Why?” if you ask to spend some money online.
One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as￡20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account.
【小题1】What does the word “They” in paragraph 1 refer to?
| A．Sellers. | B．Buyers. | C．Teenagers. | D．Parents. |
| A．More than half of the teenagers in the US and the UK have Internet access. |
| B．Teenagers pay for goods online with their own credit cards. |
| C．Most teenagers in the US and the UK have bought something online. |
| D．Teenagers found it easier to persuade parents to buy online than in a shop. |
| A．a new machine | B．special coins and notes |
| C．prepaid cards | D．pay-as-you-go mobile phones |
| A．Online shopping traps. |
| B．Internet users in the US and the UK. |
| C．New credit cards for parents. |
| D．The arrival of cyber pocket money. |

Everyone hates to wait in lines. We get that anxious feeling that our precious life is slipping away while we’re doing something so meaningless. But it’s not always the length of the wait we find so unbearable. Some people camp outside Apple stores for an entire night just to get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it.
Our behavior when waiting is only partly decided by the length of the wait. “Often the psychology of queuing is more important than the statistics of the wait itself,” notes the MIT researcher Richard Larson.
One apparent aspect of queuing psychology is that we get bored when we wait in line. This issue is solved in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our appearance.
We really hate it when we expect a short wait and then get a long one. But studies show that we are much more patient when we are given an idea of how long we’ll be waiting.
Walt Disney Co knows this better than anyone else. It posts estimated waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more quickly than they expect. It keeps them happy.
But perhaps the biggest influence on our feelings about waiting in a line has to do with our sense of fairness. When it comes to queues, the universally acknowledged standard is first come, first served. Any departure from this principle is regarded as unfair and can lead to violent queue anger.
You’ve probably experienced mild queue anger yourself in fast food restaurants, watching people in the other line zoom ahead of you, cursing yourself for having chosen the “wrong” line. In order to solve this problem, the serpentine(蛇形) line was invented. The serpentine line guides all customers into one big snaking queue, separated by ropes or barriers. When you reach the head of the queue, you are directed to the next available server, or teller, or customs official. The serpentine line isn’t always faster than multi-lines before an array(排) of cash registers. But it offers important comfort: you absolutely never have to see someone arrive after you and get served before you.
In life, waiting is inevitable. But a better understanding of the psychology of waiting can help make it a bit more bearable. When all else fails, bring a book or a smart phone will also do.
【小题1】In the 1st paragraph, the author intends to tell us_____.
| A．why people are crazy about Apple’s products |
| B．people waste their precious time in queuing |
| C．waiting time is not the only cause for people’s hate in queuing |
| D．the psychology is the real reason why people hate to wait in lines |
| A．having people queue in serpentine line |
| B．letting people know how long they will wait exactly |
| C．making people queue shorter than they are informed |
| D．offering people magazines to read when waiting in lines |
| A．make the waiting line move faster |
| B．guarantee the first-come-first-served principle |
| C．solve the problem of feeling bored in queuing |
| D．guide all customers into one big snaking queue |
| A．to explain the advantages of serpentine line |
| B．to introduce ways of saving time in queuing |
| C．to offer an explanation of the psychology of queuing |
| D．to analyze the psychology of people queuing for Apple products |
