At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse(粗糙的)wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have different exposures to environmental factors studying twins allows an “opportunity to control for genetic susceptibility(易受影响性),” Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.
But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.
Baron’s team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned(晒黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(异卵双生)and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status.
From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage.
Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors—such as smoking, being overweight, and unprotected overexposure to the sun’s damaging rays—may help motivate people to minimize these risky behaviors.

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register I said hello to an older couple who were also paying for gas.
I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.
I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holiday meaningful.
Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the lights on all day, and the battery was dead. Then I noticed that the Friendly Ford dealership --- a shop selling cars --- was right next door. I walked over and found two salesmen in the show room.
“Just how friendly is Friendly Ford?” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

The traditional distinction between products that satisfy needs and those that satisfy wants is no longer adequate to describe classes of products. In today’s prosperous societies, the distinction has become unclear because so many wants have been turned into needs. A writer, for instance, can work with paper and pencils. These are legal needs for the task. But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want.
In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main classes are convenience goods and shopping goods. Two lesser types are specialty goods and unsought(主动提供的) goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France (wine, for example) should be a specialty goods in the United States.
People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae(圣代) on a hot day. Or they may be purchased as emergency items.
Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores before making a decision. Buying an automobile is often done this way.
Shopping goods fall into two classes; those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially different include clothing, furniture, and dishes. Quality, style and fashion will either take precedence(优先) over price, or they will not matter at all.It can be learned from the first paragraph that ______.
| A．a writer needs a word processor |
| B．needs and wants can’t be separated clearly |
| C．the way to distinguish the products is unimportant |
| D．a computer is a need rather than a want |
The example of wine is used to illustrate that ______.
| A．goods are classified differently in different countries |
| B．the types of the product lie on the people rather than its nature |
| C．Frenchmen often drink but Americans sometimes do |
| D．one product may belong to many types |
Staples are items that ______.
| A．are convenient to purchase |
| B．are purchased without enough thinking |
| C．people “want but don’t need” |
| D．people are in constant need of |
Shopping goods that are considered as basically the same are those that ______.
| A．consumers don’t care where to buy them |
| B．consumers spend much time searching for |
| C．satisfy similar needs of the consumer |
| D．can be found in nearly every shop |
Downing the last drop of an expensive famous brand H2O as well as remembering to throw the empty bottle in the recycling bin, makes you feel pretty good about yourself, right? It shouldn’t. Even when the bottles are recycled, there are all kinds of other consequences of swallowing bottled water, says Melissa Peffers, the air-quality program manager for Environmental Defense.
The containers are often filled in faraway lands, then shipped from abroad, and stored in refrigerators at your local store. Compare that with the influence on environment of turning on your tap, filling a glass, and drinking up!
Anyone who is choosing bottled water for health reasons is misguided, says Peffers, “Most bottled water is just tap water.” And what comes out of your tap is carefully monitored to follow the strict rules. Consider another fact that bottled water is surprisingly expensive, especially when compared with the alternative, which is almost free, and it is astonishing that America’s desire for bottled water seems impossible to satisfy, reaching nearly 30 billion bottles a year.
“My parents’ generation never had bottled water,” says Isabelle Silverman, an Environmental Defense legal adviser. She has made a commitment to going bottle free. “You don’t need to fetch it home from the store, and it’s cheaper,” she adds.
Bottled water’s role as a status symbol needs to change, Peffers points out. So when a waiter at an expensive restaurant offers “And what’s your drink?” that’s no reason to forget your conviction(信念). “Don’t be afraid to say, ‘I’ll have tap.’ Say it loud enough that the other tables nearby can hear you,” Peffers says. “And then spend that money on a dessert.”In the first paragraph, the underlined sentence “It shouldn’t.” suggest that people _______.
| A．shouldn’t feel pleased with finishing the water in the bottle. |
| B．shouldn’t feel good about drinking an expensive brand H2O. |
| C．shouldn’t be pleased with just recycling empty bottles. |
| D．shouldn’t be satisfied with drinking only bottled water. |
According to the author, tap water is _______.
| A．as safe as bottled water | B．morel likely to be polluted |
| C．healthier than bottle water | D．less convenient than bottled water |
The underlined part “going bottle free” (in Para. 4) means “_______”.
| A．making bottled water free | B．giving up bottled water |
| C．recycling use water bottles | D．providing free water containers |
Why does Peffers ask people to say “I’ll have tap.” Loudly?
| A．To encourage them to set an example for others to follow. |
| B．To advise them to save the money for one more dessert. |
| C．To remind them to be aware of their social status. |
| D．To persuade them to speak confidently in public. |
John Blanchard was studying the crowd making their way through the station. He was looking for the girl whose heart he knew, but whose face he didn't, the girl with the rose.
When reading a book in a Florida library a year before, John became interested not in the contents of the book, but in the notes penciled in the margin. The handwriting reflected a thoughtful soul and beautiful mind. He discovered the former owner's name in the front of the book: Miss Hollis Maynell.
He located her address and wrote a letter introducing himself. The next day he was shipped overseas to serve in the army. During the next year, they grew to know each other through the mail and their friendship developed. John requested a photograph, but she refused, saying if he really cared, it wouldn't matter what she looked like. When the day finally came for him to return home, their first meeting was suggested — 7:00 p.m. at the Grand Central Station in New York.
She wrote, “You’ll recognize me by the red rose I wear on my coat.” So now John was in the station to meet the girl with a rose.
As a pretty and slim girl in green came over, John noticed her blue eyes like flowers in spring. He walked directly towards her, entirely forgetting she was not wearing a rose. As John came closer to her, he saw another woman with a red rose stood nearby. Well past 40, this woman had graying hair done under a worn hat. Seeing the girl in green walk quickly away, John felt as if he were split in two. He desired to follow that girl, but longed for the woman whose spirit had truly companioned and supported him.
The woman looked gentle and sensible. John went to her, saying, “I’m Captain John Blanchard. You must be Miss Maynell. I am glad to meet you here. May I take you to dinner?”
She replied with a smile, “I don’t know what this is about. But the lady in green who just went by, begged me to wear this rose on my coat. She said if you asked me out to dinner, I’d tell you she is waiting for you in the big restaurant across the street.

We often hear people talking about a generation gap (代沟). The name is new,but the idea is old. Young people and their parents don’t understand each other. The world has always kept changing. During the second century after Christ a wise man said, “Bury me on my face because in a little while everything will be turned upside down.” There has always been a gap between generations, but more people talk about it now. Old Mr. Ellis thinks he understands what has happened. “When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But when I was older, I learned about people who were treated badly, people who didn’t have enough to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to meetings and talked a lot, but it didn’t seem to make much difference. ”“Our children grew up in a world at war. They didn’t know when the fighting would stop. They wanted their children to have nice clothes and toys. They didn’t want to think about the future. They thought nothing could be done about it.” “Now I have grandchildren, and they have their own ideas. They are trying to make the world better. They are trying to help other people. They’re making people listen to them. I am proud of their generation.” The wise man mentioned in the text told people to bury him on his face so that when everything is turned upside down he will _____.
| A．lie on his stomach | B．lie on his back |
| C．stand quietly | D．sit in peace |
Which generation did NOT want to do anything to make the world a better one?
