Your cell phone holds secrets about you. Besides the names and   50   that you’ve programmed into it, traces of your DNA remain on it, according to a new study.
　　DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you   51   you have an identical twin. Scientists today routinely analyze DNA in blood, saliva (唾液), or hair   52   behind at the scene of a crime. The results often help detectives identify   53   and their victims. Your cell phone can   54   more about you than you might think.
　　Meghan J. McFadden, a scientist at McMaster University1in Hamilton, Ontario, heard about a crime in which the suspect（嫌疑犯）bled onto a cell phone and later dropped the   55  . This made her wonder whether traces of DNA remained on cell phones ___ even when no blood was involved.　    56   she and colleague Margaret Wallace of the City University of New York analyzed the flip-open phones(翻盖手机) of 10 volunteers. They used swabs(药签) to collect   57   traces of the users from two parts of the phone: the outside, where the user holds it, and the   58  , which is placed at the user’s ear.
The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to   59   all detectable (可查明的) traces of DNA. The owners got their phones back for another week.   60   the researchers collected the phones and repeated the swabbing of each phone once more.
The scientists discovered DNA that   61   to the phone’s owner on each of the phones. Better samples were collected from the outside of each phone, but those swabs also   62    DNA of other people who had apparently also handled the phone.   63  , DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won’t remove all traces of evidence from a criminal’s device. So cell phones can now be added to the   64   of clues that can settle a crime-scene investigation.

Who owns the large American companies that produce cars, washing machines, and television sets? They are owned by a large group of people called stockholders.

　　A company must have money to build factories and to buy machinery. To get this money, it sells shares of stock（股份）. Each share of stock is a share in the ownership of the company. The person who buys a share of stock becomes a part owner of the company. He is called a stockholder. A company can have thousands of stockholders. Sometimes a very large company is owned by millions of stockholders.

　　Few persons can afford to buy a whole company, but the average individual can become part owner of a business. He can save his dollars and buy a share of stock in a large company. A person does not have to be wealthy to be a stockholder.

　　When a company makes money, each stockholder may receive a dividend(股息) check, which is his share of the profits（利润）. Parts of a company’s profits are not paid out to the stockholders. This money is used by the company so it can grow larger. If the company does well, its shares of stock become more valuable.

　　More than 20 million people own shares of stock in America’s companies. By owning stock, they are helping America’s businesses grow. They are also putting their money to work to earn more money.

As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.

         Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long hours work culture to make more money is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them. Six percent of workers in Britain took the decision to downshift last year.

         One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs, leaving their two children with a nanny. Most evenings Daniel wouldn’t get home until eight or nine o’clock and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by.

　　Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm then,” says Daniel, “and we took almost a year to make the decision to downshift. It’s taken some getting used to, but it’s been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it’s made us stronger as a family, and the children are a lot happier.

　　Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I’m not really a country girl, but I suppose I’m gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much or you might not do it at all.”
