Tobacco is the second major cause of death in the world. It is responsible for the death of one in ten adults worldwide (about 5 million deaths each year). If current smoking patterns continue, it will cause some 10 million deaths each year by 2020. Half the people that smoke today, that is about 650 million people, will eventually be killed by tobacco.
Tobacco is the fourth most common risk factor for disease worldwide. The economic costs of tobacco use are equally devastating (破壞性的). In addition to the high public health costs of treating tobacco-caused diseases, tobacco kills people at the height of their productivity, depriving (剝奪) families of breadwinners(養(yǎng)家糊口的人) and nations of a healthy workforce. Tobacco users are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of 200 thousand million US dollars, a third of this loss being in developing countries.
Tobacco and poverty are closely linked. Many studies have shown that in the poorest households in some low-income countries as much as 10% of total household expenditure is on tobacco. This means that these families have less money to spend on basic items such as food, education and health care. It contributes to a higher illiteracy rate, since money that could have been used for education is spent on tobacco instead.

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize.
Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants（嬰兒）are able to quantify substances（物質(zhì)）—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food.
With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount.
“Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” vanMarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.”
This information further refutes（駁斥）the long-held idea that babies “know nothing of the world,” vanMarle said.
“Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” vanMarle said.
In the future, vanMarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study.
小題1:The quantifying ability refers to the ability to     .
A．choose between different substances
B．get much knowledge of the world
C．describe the quantity of something
D．obtain math-related skills
小題2: What is mainly talked about in Paragraph 4?
A．The process of doing research.
B．The scientific findings.
C．The final choice of infants.]
D．The observation of infants’ behavior.
小題3:Babies choose the larger amount of food     .
A．by saying numbersB．with the help of parents
C．on personal preferenceD．through their natural abilities
小題4:We can learn from the text that     .
A．some parents don’t care about their kids

C．little research has been done on infants
D．scholars disagree on baby-training programs

In much society, there is often greater acceptance of light skin than dark skin; Light skin may be seen as a mark of beauty, intelligence and success. These beliefs can lead to social pressures even within the same group, if some members are darker than others.
The result is that skin lightening has become very common across Africa, Asia and other areas of the world and more people with dark skin are using skin-lighting products, even if it means they may face health risks. They believe that having whiter skin will improve the quality of their lives. Many people think they will have a better family. Or they want to look like what their society generally considers beautiful.
Some beauty care（美容） products and soaps contain chemicals that make skin lighter. However, some of the chemicals are extremely dangerous. The chemicals in the products block and break down the natural barrier(障礙) to protect against sunlight. Then the skin can become thick and discolored. Usually the person will use more of the product in an effort to correct the problem, which just makes things even worse. Doctor Ly says some chemicals are so dangerous that they may lead to blackened fingernails, infections(感染) and serious skin damage.
And these are not the only problems. Experts say some people who change their skin color suffer emotional damage. They feel regretful and sad. They feel that instead of risking their health, they should have learned to live and accept their skin color as it was.

Younger adults who get either little sleep or a lot of it may see a greater expansion in their waistlines（腰圍）over time, a study published suggests. Researchers found that among black and Hispanic adults younger than 40, those who typically slept for five hours or less each night had a greater accumulation of belly fat over the next five years, versus（相比于） those who averaged six or seven hours. Those who slept eight hours or more in bed each night also showed a bigger fat gain - but it was less obvious than that seen in "short sleepers."
The study, reported in the Journal Sleep, does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration - particularly a lack of sleep - to weight gain and even to higher risks of diabetes(糖尿病) and heart disease. Among participants younger than 40, the study found, those who said they slept for five hours or less each night gained more belly fat than those who averaged six or seven hours of sleep. On average, short sleepers showed a 32 percent gain in visceral（內(nèi)臟的）fat, versus a 13 percent gain among those who slept six or seven hours per night, and a 22 percent increase among men and women who got at least eight hours of sleep each night. A similar pattern was seen with superficial abdominal（腹部）fat.
The findings, according to lead researcher Dr. Kristen G. Hairston, support the belief that sleep habits affect weight and health in general. "Sleep is an important part of your overall health - not just in whether you're tired during the day," she said.
There may be indirect effects; people who get too little sleep may be too tired during the day to exercise, while those who spend a lot of time in bed may spend less time being active, relative to people who sleep fewer hours. Research also suggests that sleep loss alters people's levels of appetite-regulating hormones（荷爾蒙）- which could, in theory, cause them to overeat. Depression, which often affects people's sleep and has been linked to weight gain, could also be a factor, Hairston noted.
小題1:Who may have the higher risk of being fat over the next five years?
A．Jack, a Hispanic man, aged 35, sleeps for 3 hours every night.
B．Candy, a black woman, aged 41, sleeps for about 5 hours every night.
C．Bob, an American, aged 50, sleeps for more than 12 hours every day.
D．John, a student in Africa, sleeps for more than 6 hours every week.
小題2:What does the study, reported in the Journal Sleep find?
A．Too little or too much sleep directly gives rise to the fat gain.
B．People are subject to heart disease due to the lack of sleep.
C．It is admitted that sleep plays an important part in our health.
D．Researchers find a longer sleep time is better for our health.
小題3:What does the lead researcher Dr. Kristen G. Hairston agree with?
A．People should do some exercise in their daily life.
B．There is a close link between sleep habits and health.
C．More nutrition is greatly needed when we lack sleep.
D．More and more people tend to sleep less than before.
小題4:What can we infer from the passage?
A．Younger adults getting little or much sleep may become fat.
B．We are supposed to do exercise as much as possible to keep fit.
C．We should keep a good sleep habit to improve our health.
D．We have to spare no efforts to drive depression away.
小題5:What’s the best title of the passage?
A．Sleep Habits Linked to Fat Gain in Younger Adults.
B．Doing Exercise Is the Best Way to Keep Fit.
C．Our Waistlines Can Be Driven Away Right Now.
D．Diabetes No Longer bother all of Young People.

The Touchstone
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man, who could read a little, bought it for very little money.
The book wasn’t very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the “Touchstone”! The touchstone was a small pebble that could turn any common metal into pure gold.
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea.
The days stretched into weeks and the weeks into months. One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are careful, it’s easy to fail to recognize an opportunity when it is in hand, and it’s just as easy to throw it away.
小題1:The man bought the book because _____________.
A．he wanted to read itB．it was very interesting
C．there was a secret in the book D．he wanted to find the touchstone
小題2:We can learn from the passage that the touchstone is _________.
A．pureB．coldC．magicD．big
小題3:Why did the man throw the pebbles into the sea?
A．Because he didn’t want to get the same pebbles.
B．Because he didn’t want others to pick them up.
C．Because he didn’t like their ordinary looks.
D．Because he didn’t like the cold feelings.
小題4:What does the author want to tell us in the passage?
A．We should offer opportunities in our life.
B．We should seek for opportunities in the world.
C．We may seize opportunities when we are watchful.
D．We may discover opportunities when forming habits.

The holiday's upon us. Finally, after months of study, you have some time to yourself. so, why not read a book? Well, some people will say, "Why bother with books? We have the Internet and other media that offer a lot more colorful entertainment. Books are history!" But don't be fooled. There's still a lot to be said for reading.
One clear reason is that a well-chosen book is a wonderful source of vocabulary, so long as you have a good dictionary, of course. Believe me, it's far easier to get new English words and phrases from a book or article than it is from the TV or the Internet.
But an even more important point is that books give you something that modern media simply can not. The average webpage is picture-heavy and the text is often designed to make it as easy to read as possible. While "easy" may be attractive, unfortunately it's little use for many long-term development of reading skills and the general language level. For that, there's still no substitute (替代品）of a book.
But perhaps the best single reason is that simply choosing what you read and doing it independently means that it's something you do by yourself. You can choose what you want to read. It's hard work, but something down the line, you will find that what once seemed like a duty is now a pleasure. We asked three bookworms -- an English teacher, a book editor and a film critic - to pick some favorite reads for you.
小題1: How many reasons for reading a book does the author mention in the passage?
A．OneB．TwoC．ThreeD．Four
小題2: According to this passage, we basically need a ______ in reading.
A．computerB．dictionaryC．notebookD．pencil
小題3:In the author's opinion, reading on the Internet may ________
A．develop long-term reading skillsB．improve the general language ability
C．not take the place of reading booksD．be an effective way of reading
小題4: The passage is written mainly to ____________.
A．share the pleasure of reading booksB．a(chǎn)dvise readers to read books
C．stress the importance of reading online.D．help readers to choose good books.

Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some kind, football, hockey, golf or tennis. It may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game. There are no manmade rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between teams of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously team work. The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment.
小題1:Which of the following can be the best title for the passage?
A．Differences between Golf and Mountaineering.
B．Sports and Games.
C．Mountaineering.
D．Why are so many people crazy about mountaineering?
小題2: The biggest difference between golf and mountaineering lies in ____.
A．team game
B．enjoyment
C．a(chǎn)ge
D．rules
小題3:The mountaineering can also be called a team sport because ____.
A．mountain climbers usually compete in groups
B．mountaineers depend on each other while climbing
C．mountaineering climbers are free to use their won rules to climb
D．mountaineering is a sport not a game
小題4: In the author’s opinion, one of the most important reason why so many people enjoy
mountaineering is that ____.
A．there are no man-made rules for mountaineers
B．mountaineering is a sport and not a game
C．it is one of the most dangerous sports
D．mountaineering brings us more enjoyment than other sports
