The Come-back Coffeehouse   The sign in the window read "Carl's Coffee Shoppe," spelled the old-fashioned way. Hallie shook her head and wondered how many times she had suggested an alternative. She entered the shop and saw only one person.

    "I could help with the books, Dad", Hallie offered,"There's not much you could do." Her father signed. "How about if you clean the counters instead?" His statement made her feel like a little girl instead of a senior in high school. Hallie sprayed some cleanser and ran a cloth over the worn counter tops . After she had washed a few of the old eggshell-colored cups, she began her homework. At closing time, Hallie's parents sat beside her. "You know the shop has not been profitable lately," Mr. Rhodes began. "We need to decide if it is even worth keeping it open." "We're going to visit Uncle Harold over spring vacation." Mrs. Rhodes continued. "He can look over the books and tell us what our options are. You and AuntTess will run the shop for the week."

    By spring vacation Hallie was ready for an adventure. Hllie's parents gave some instructions, and said good-bye. Hallie stared absently out the window at the passersby: young people on their way to work, and kids on their school vacation. They were not the same people that her grandpa Carl had served. Suddenly Hallie had an idea. She confided in Aunt Tess, who approved. The two eagerly set to work.

At the end of the week, Hallie was coming out from the kitchen when she saw her parents standing in the shop, confused. She smiled asher parents stared at the teens around the counter and the young families seated at the tables.

    "Welcome back!" Hallie swept her arms to present there staurant's cheerful new decoration. Bright, attractive coverings spread over the tables, and modern posters hung on the walls, while, colorful mismatched dishes contributed to the pleasant atmosphere."

    "I brought board games from home," Hallie added excitedly, "and the bookstore down the street donated the posters. When we talked to our friends about what we were doing, they were happy to give us some dishes." Hallie held her breath as she waited for her parents' reaction.

    "Everyone certainly seems to like the changes," noted Mrs. Rhodes.

    "Speaking of changes," Mr. Rhodes said,"I see our name has changed, too."

    "Do you mind? I changed our name to 'Come-Back Coffeehouse'to make the shop sound welcoming, as in 'Please come back again'..."

    A smile spread across her father's face. "The newname is fitting. Thanks to you, this place certainly has made a come back!"

    The brain of an insect isn't very big. But insects are somehow still able to make lots of important decisions. Bees, ants and roaches(蟑螂) build hives(巢穴)with thousands of workers doing specialized work. The jobs are done without a head or even a plan. How do insects manage this?

    To solve the mystery, scientists in Belgium spent months building robotic roaches and then putting them among real roaches. The final goal of the research is to find out how the simple behavior of individuals gives rise to a collective decision. The roach is a good starting point for trying to answer the big question because its social system is simple enough for scientists to study.

    The first step was to build robots that real roaches would accept as their own. Although the robotic roaches don't look much like the real thing, they have similarities with them in three key ways: they naturally head toward dark areas, they are influenced by the behavior of other roaches, and even more importantly, they smell like roaches.

    The next step was getting the robotic and real roaches to work together on common tasks. In experiments, the robots would collectively head towards a dark place, copying the behavior of natural roaches. That got the researchers wondering: if you program the robotic roaches to go woward the lighted place, would the real roaches follow, going against their natural instincts.(本能) ?

    They will – it turned out. Many of the real roaches followed the robots to a lighter shelter. But influence turned out to be a two- way street. On occasion, the real roaches were able to override the programming of the robot roaches and get them to turn into dark hiding places. Being social creatures, both the robotic and natural roaches were paying attention to and following the example set by others.

    In theory, it would be possible to create a robot that could influence collective decision-making in humans. To do this, researchers would have to invent a robot that people would accept. Fortunately, the technology isn't there yet.

    Being less than perfectly well-dressed in a business setting can result in a feeling of great discomfort that may well require treatment to eliminate. And the sad truth is that “clothing mismatches” on the job can ruin the day of the person who is wearing the inappropriate attire(着装)—and the people with whom he or she comes in contact.

    Offices vary when it comes to dress codes. Some businesses have very high standards for their employees and set strict guidelines for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company's attitude is regarding what you wear, you are working in a business environment and you should dress properly. Certain items may be more appropriate for evening wear than for a business meeting, just as shorts and a T-shirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior vice president has a different image to maintain than that of a secretary or sales assistant. Like it or not, you will be judged by your personal appearance.

    This is never more apparent than on “dress-down days”, when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dress-down days than on “business professional ” days. Thus, when dressing in “business casual” clothes, try to put some good taste into your wardrobe choices, recognize that the “real” definition of business casual is to dress just one notch(等级) down from what you would normally wear of business-professional attire days.

    Remember, there are borders between your career and our social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress properly and you will discover the truth in the principle that clothes make the man—and the woman. When in doubt, always misjudge on the side of dressing slightly more traditionally than the situation demands.

    It's been a hard time for rhinos (犀牛) lately. Recently the International Union for Conservation announced the western black rhinos had died out in the wild. It was last seen in western Africa in 2006. Now, those who work to protect the animals are trying to make sure that won't happen to other rhinos.

    19 south-central black rhinos in South Africa were driven to an area nearly 1,000 miles away, which was said to be the gentlest and quickest way to transport the animals. They were taken to a new home that would keep them safe from hunters.

    Though it is not allowed to hunt rhinos, many are still killed for their horns, which can sell for as much as $ 30,000 each. Most of them are used to make drugs as traditional medicines in Asian countries. Some people believe that the horns work well in treating pain, fever and even cancer. However, there is no medical evidence yet.

    Black rhino population began falling rapidly in the second half of the 1900s because of poaching. In fact, some people still hunt the animals at the risk of being put into prison. And many of the places where the animals used to live in were destroyed when people started building farms on the grasslands. Until the 1960s, about 65,000 black rhinos lived throughout most of Africa. Today, fewer than 5,000 are left—most of them in zoos and wildlife reserves.

    South Africa has the largest population of rhinos in the world. Poaching is an especially big problem in that country. So far, more than 340 rhinos have been killed there. Since 2003, the Black Rhino Expansion Project has been helping the south-central black rhinos in South Africa. The group works with landowners to find areas where rhinos can live safely away from hunters.

    So far, the group has successfully saved about 120 rhinos. Leaders of the project say the south-central black rhinos have seen a rise in numbers. It is hoped that, with continued support, these rhinos can escape the unfortunate result of the western black rhinos.

How Important Is Fashion?

    Is looking fashionable more important than being comfortable? Many people seem to think so, judging by the things they wear. But fashion is not everything. It is more important to be a healthy and good person.

    People go to great lengths to be fashionable. Some people think they have to have a certain body type, so they go on extreme, unhealthy diets in order to change their bodies. In addition, many women wear uncomfortable fashions, such as high-heeled shoes that create blisters（水泡）, tight body shapers that limit blood flow, and sticky false eyelashes. Men and women alike spend time and money on products that change their natural hair color and use hot irons and blow dryers to curl or straighten their hair. Some people spend several hours a day in front of a mirror. Is fashion important enough to spend so much time and effort on changing how you look like?

    If the purpose of fashion is to make a person feel good, it does not make sense that he or she would go through so much discomfort to be fashionable. Fashion should not come first. People should prioritize（优先考虑）being healthy and positive. What people wear does not indicate anything about their personalities. Instead of spending hours choosing a suit, perhaps you should call your friends and do something together! Instead of going on strict diets and starving, why not eat some healthy foods and then exercise? By doing these things, you can keep a healthy lifestyle and truly grow as a person.
