One of the most debated issues about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do.The standard Alcoholics Anonymous explanation for this finding is this：many of those who give up alcohol are actually former hard­core drunks who had already brought health problems associated with drinking.

    But a new paper suggests that abstaining(戒除)from alcohol does tend to increase one's risk of dying，even when you leave former problem drinkers out.The most shocking part—abstainers'(禁酒者)mortality rates(死亡率)are higher than those of heavy drinkers.

    Moderate(适度的)drinking，which is defined as one to three drinks per day，is associated with the lowest mortality rates.Moderate alcohol use is thought to improve heart health，circulation and sociability，which can be important because people who are cut off don't have as many family members and friends who can notice and help treat health problems.

    But why would abstaining from alcohol lead to a shorter life？It's true that those who abstain from alcohol tend to be from lower socioeconomic classes，since drinking can be expensive.And people of lower socioeconomic status have more life stressors(压力因素)．

    Though heavy drinking is associated with higher risk for many diseases，heavy drinkers are less likely to die than don't drink. One important reason is that alcohol strengthens social interactions，and social interactions are vital for maintaining mental and physical health.Nondrinkers show greater signs of depression.

    The authors of the new paper are careful to note that even if drinking is associated with a longer life，it can be dangerous：it can affect your memory severely and it can lead to falls and other troubles that can affect your life.There's also the dependency issue：if you become addicted to alcohol，you may spend a long time trying to get off the bottle.

    Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.

    {#blank#}2{#/blank#} people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products' safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.

    Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.

    {#blank#}3{#/blank#}The safety belt's main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.

    Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy.  {#blank#}4{#/blank#} Effective as they are, they can't take the place of safety belts.

    Drunk driving crashes are less likely to happen if you don't drink. {#blank#}5{#/blank#}Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.

A. How to drive safely?

B. You are safer in a large car

C. How to protect ourselves in the highway?

D. Air bags are not installed in all cars.

E. That's why safety belts should be worn.

F. Drunk driving is the most serious problem.

G. But the protection provided by air bags is limited in side or rear crashes.

    Throughout the history of the arts, the nature of creativity has remained constant to artists. No matter what objects they select, artists are to bring forth new forces and forms that cause change—to find poetry where no one has ever seen or experienced it before.

    Landscape is another unchanging element (元素) of art. It can be found from ancient times through the 17th­century Dutch painters to the 19th­century romanticists (浪漫主义艺术家 ) and impressionists. In the 1970s Alfred Leslie, one of the new American realists, continued this practice. Leslie sought out the same place where Thomas Cole, a romanticist, had produced paintings of the same scene a century and a half before. Unlike Cole who insists on a feeling of loneliness and the idea of finding peace in nature, Leslie paints what he actually sees. In his paintings, there is no particular change in emotions and he includes ordinary things like the highway in the background. He also takes advantage of the latest developments of color photography to help both the eyes and the memory when he improves his painting back in his workroom.

Besides, all art begs the age­old question: What is real? Each generation of artists has shown their understanding of reality in one form or another. The impressionists saw reality in brief emotional effects, the realists in everyday subjects and in forest scenes, and the Cro­Magnon cave people in their naturalistic drawings of the animals in the ancient forests. To sum up, understanding reality is a necessary struggle for artists of all periods.

    Over thousands of years the function of the arts has remained relatively constant. Past or present, Eastern or Western, the arts are a basic part of our immediate experience. Many and different are the faces of art, and together they express the basic need and hope of human beings.

    Alibaba, Bank of China and Huawei—these are the dream employers for Chinese students, according to a new survey.

    “The survey of more than 55,000 students, conducted by the research firm Universum, has found that roughly a quarter want to work for an international company, while only 9％ want to work for a start-up. Five percent want to start their own business.”

    The students said that work-1ife balance was the most important career goal, followed by job stability. When it comes to desirable companies, Bank of China has been named the top choice by business students for seven consecutive years, and the gigantic state-owned firm shows no signs of giving up its lead.

    William Wu, the China country manager for Universum, said that banking remains an attractive industry for young Chinese. “China's government is now emphasizing the revolution of the finance industry, which leaves the younger generation with the impression that although banking is a traditional industry, there are still a lot of development opportunities.” Wu said.

    E-commerce giant Alibaba (BABA, Tech30) improved six places from 2014, ranking second among business students. Alibaba's rise shouldn't come as much of a surprise—the company held a record-breaking $25 billion IPO in September.

    Among engineering students, Alibaba was once again a bridesmaid. Instead, Huawei—a telecoms infrastructure firm that now makes consumer products-took the top spot.

    “Both of these companies are pioneers in terms of local companies going international.” said Wu. “It shows that… an international development strategy has a positive influence among Chinese young talents.” Tech companies ruled the rankings for humanities students, with Alibaba—which was ninth in 2014 —landing at the top. Last year, Apple was the Number l choice of Chinese students.

    The English language has a lot of words which can be used in many different ways and in many different experiences.

    One such example is the word matter. In fact, matter can mean just about anything. It could be one of the most useful words in the English language.

Let's get to the heart of the matter —- a matter of principle(原则).

    If someone says that you owe(欠) him $50, but you don't, a friend might say, "Well, you could pay him the $50. It's not that much money. Then you won't have to hear him say it anymore." But if you do not owe him the money, do not pay him the money. It's a matter of principle.

    There is another way to use the word matter. But be careful with your choices of words.

    If you ask someone, "What's the matter?", it shows you are worried about the other person. But saying, "What's the matter with you?" has a completely different meaning. And it usually sounds rude. In fact, when you say, "What's the matter with you?", you are suggesting that the person did something wrong or stupid.

    Another expression that could sound rude is to say, "It doesn't matter to me." Here, it depends on the context, and how you say it.

    Let's say you tell someone that a friend just got a big raise at work. That person answers with, "It doesn't matter to me." Here, it means he or she does not care. And it sounds rude.

    But saying, "Oh, you pick where we eat dinner. It doesn't matter to me." does not sound rude. In the situation, "it doesn't matter" shows you are easy-going.

    No matter how you look at it and what you say, matter is a very useful word. And it's only a matter of time before you will become an expert on the use of matter.

    Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined (限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.

    At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic (器官的) disease, that destroys brain cells.

    Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, and then the patient's memory begins to fail. He may forget dates, numbers, names and plans.

    As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.

In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

    Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus (病毒). It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
