Unusual incidents are being reported across the Arctic. Inuit（因纽特人）families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud. There are also reports of sea ice breaking up earlier than usual, carrying seals beyond the reach of hunters. Climate change may still be a rather abstract（抽象的）idea to most of us, but in the Arctic it is already having great effect—if summertime ice continues to shrink at its present rate, the Arctic Ocean could soon become almost ice-free in summer. The knock-on effects（连锁反应）are likely to include more warming, cloudier skies and higher sea levels. Scientists are increasingly eager to find out what’s going on in the Arctic.
For the Inuit the problem is urgent. They live in unsteady balance with one of the toughest environments on earth. Climate change, whatever its causes, is a direct danger to their way of life. Nobody knows the Arctic as well as the locals, which is why they are not content simply to stand back and let outsider experts tell them what’s happening. In Canada, where the Inuit people are trying hard to guard their hard-won autonomy（自治权）in the country’s newest land, Nunavut, they believe their best hope of survival in this changing environment lies in combining their ancestral (祖先的) knowledge with the best of modern science. This is a challenge in itself.
The Canadian Arctic is a vast, treeless polar desert that’s covered with snow for most of the year. Adventure into this area and you get some idea of the hardships facing anyone who calls this home. Farming is out of the question and nature offers few pickings. Humans first settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea first. The environment tested them to the limits: sometimes the settlers were successful; sometimes they failed and disappeared. But around a thousand years ago, one group appeared that was uniquely well adapted to deal with the Arctic environment. These Thule people moved in from Alaska, bringing dogs, iron tools and the like. They are the ancestors of today’s Inuit people.

How long you live has a lot to do with your environment and lifestyle, but exceptional(特别的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因谱)that accurately predicts who may live to 100 and beyond.

Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(标志基因组). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”

Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.

It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.

1.Which of the following is TRUE according to Paragraph 2?

A. Most long-living people have special long-life-related genes.

B. Ninety percent of the participants lived to 100 years of age. 

C. All the long-living people have only one signature genetic cluster.

D. Scientists know how the integration of the genes helps people live long.

2. Perls may most likely agree that         .

A. most people living extremely long benefit from not smoking 

B. living longer just depends on certain genetic recipes

C. environmental factors play an important role in long-living

D. being mentally active has nothing to do with living an old age

3. Which of the following is FALSE according to the text?

A. Remaining socially engaged helps a person to live long.

B. A genetic recipe can accurately predict who may live to 100 and beyond.

C. Perls is the first to think living longer is just a matter of genes.

D. The older he gets, the more likely the genes contribute to his extended years.

4.Which of the following would be the best title for the text?

A. Genes May Predict Who Lives to 100         B. Environment And Genes

C. Genes, the Secret of Long Living           D. Lifestyle And Genes

From hitting the mall with your girl friends on a Saturday afternoon, to holiday spending on gifts that go under the tree, shopping could be called one of America’s favorite pastimes. For most people, it means some new clothes for work or a small trinket for a friend. For others, however, shopping is much more than an enjoyable pastime, and in some cases, it is a real and destructive addiction that can turn into a financial disaster. Compulsive shopping and spending are defined as inappropriate, excessive过度的, and out of control. Like other addictions, it basically has something to do with impulsiveness and lack of control over one’s impulses冲动. In America, shopping is embedded in our culture; so often, the impulsiveness comes out as excessive shopping. Sometimes this is referred to as “shopholism”. Shopping addiction can damage a person’s life, family, and finances. “No one knows what causes addictive behaviors, like shopping, alcoholism, drug abuse, and gambling”, says a professor of applied health science. Some of the new evidence suggests that some people, maybe 10%-15%, may have a genetic predisposition to an addictive behavior, coupled with an environment in which the particular behavior is triggered引发, but no one really knows why.” Individuals will get some kind of high from an addictive behavior like shopping.

What are the telltale signs that shopping has crossed the line and become and addiction? What should a concerned family member or friend look out for when they think shopping has become a problem? The behaviors can signal a serious problem:

·Shopping or spending money as a result of feeling angry, depressed, anxious, or lonely

·Having arguments with others about one’s shopping habits

·Feeling lost without credit cards — actually going into withdrawal without them

·Buying items on credit, rather than with cash

·Describing a rush or a feeling of euphoria with spending

·Feeling guilty, ashamed, or embarrassed after a spending spree(大买特买)

·Thinking obsessively about money

·Spending a lot time juggling accounts or bills to accommodate spending

“If someone identifies four or more of any of these behaviors, there may be a problem”, experts say. Treating a shopping addiction requires a multifaceted approach. There are no standard treatments for shopping addiction. Medications have been used, but with mixed results. Therapists also focus on cognitive-behavioral treatment programs. There is no quick and easy answer that will immediately cure a shopping addiction, and while treatment is a necessary part of solving the problem, so is behavior change on the part of the addict.

Some basic changes in behavior that will have a big impact on breaking a shopping addiction are recommended:

·Admit that you are a compulsive spender, which is half the battle.

·Get rid of checkbooks and credit cards, which fuel the problem.

·Don’t shop by yourself because most compulsive shoppers shop alone and if you are with someone you are much less likely to append more.

·Find other meaningful ways to spend time.

And keep in mind that while behavior change is clearly important to recovery, so is reaching out for professional help.(509)
