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!"

    Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.

    So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don't we use them for collecting energy?

    The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?

    The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.

    Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.

    We just can't wait to see more of these roads all over the world in the near future.

When milk arrived on the doorstep

    When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn't take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.

    Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note-“Please add a bottle of buttermilk next delivery”-and place it in the box along with the empty bottles. And then, the buttermilk would magically appear.

    All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn't freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.

    There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.

    Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch （门廊）. Every so often my son's friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

    Nowadays, a new method is used to decide who are the top students in school. The best students are those who not only get high marks, but also follow the rules and the behavior standards for middle school students. Here are some of the new rules and standards.

    Tell the truth. Have you ever copied someone else's work in an exam? If you have, then don't do it again! That's not something an honest student should do. If you have played computer games for two hours in your room, don't tell your parents you were doing your homework.

    Learn to be loving and caring. Good students love animals and care about other people.

    Learn to work together with others. It would be more fun when more people work together. Did you quarrel(争吵) with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, instead of only yourself.

    Be open to new ideas. Have you ever thought that people could live on the moon? Perhaps you'll discover Earth II some day. Don't look down upon new ideas. Everyone's ideas are important. You should welcome them, because new ideas make life better for everyone.

    Use the Internet carefully. The Internet can be very useful for your study. Some websites on the Internet are not for kids, so make sure to visit the web pages that are good for you. You can use the web for fun or homework. Can't you find any good websites for children?

    Women in northern European nations are closest to equality with men on wages, education, health and education. That is the finding of a report by the World Economic Forum. The United States ranked 28th. On Friday, President Barack Obama announced the government will require large businesses to report how much they pay men and women. The data will be used to target companies that pay women less to do the same jobs.

    According to the World Economic Forum report, women worldwide continue to lag behind men on wages. Based on current trends, they will need 126 years to catch up, according to the report. Women are making progress. But they still only earn what men did 10 years ago, say the report's authors. The report measures the gender gap for women in 145 nations for health, education, economic opportunity, and political power. Women have not achieved equality in any of the 145 nations included in the survey, says the report.

    Women came closest to equality in four Northern European nations – Iceland, Norway, Finland and Sweden. Ireland ranks No. 5. At the bottom of the women's gender ratings are Yemen, Pakistan, Syria, Chad, Iran and Jordan.

    More women than men are attending colleges in 97 nations. But women make up a majority of skilled workers in only 68 nations. Women control the majority of government and political positions in only four.

    At last week's World Economic Forum in Davos, Switzerland, Sheryl Sandberg, chief operating officer at Facebook, spoke about gender equality. “The reason to work towards equality – whether woman or man – is that it is better for you,” Sandberg said. “We should be doing this not because it's the right thing, but because it's the smart thing. Do it because it will help you.” The World Economic Forum completed its worldwide 2015 gender gap survey in November.

    A society that lives by the plastic fork may very well die from it. That's how things are looking. Anyway, for a world so used to disposable(一次性的) habits, any hope for a solution(解决方案) also increasingly seems to be buried.

    Sure, there have been some hopeful ideas. Boyan Slat, the Dutch inventor developed a plan for Covering the Great Pacific Garbage Patch. Not long after it started, Slat's system experienced "material fatigue(疲劳)"-likely the result of being strained(使受到压力) by all that trash-and the task was delayed.

    All the while, the plastic increases. Its growth is very fast, according to Linda Wang, a professor of chemical engineering at Purdue University. She says, "We'll have more plastic than fish by 2050." Yet Wang, along with other researchers at Purdue, may have a solution not only to this plastic problem, but also to the growing need for clean energy.  Her team has developed a system that turns waste, a durable, lightweight material that accounts for about a quarter of all plastic waste, into a highly pure form of gasoline.

    Publishing their findings in the journal Sustainable Chemistry and Engineering, the scientists' state that instead of making plastic go away, they can break it down and reuse it, using chemistry to destroy what chemistry brought to the world when plastic was developed back in 1907.

    The process uses "supercritical" water-heated to around 450 degrees Celsius (842 degrees Fahrenheit),beyond the key point at which distinct liquid and vapor phases(气液态) exist-to boil plastic waste into an oil, the researchers explain. It takes a couple of hours for the supercritical water to complete the transformation, but the result is a kind of oil that can be used as gasoline or fuel. It can also be turned into other products.

    The researchers have only made the transformation in a laboratory setting so far, but they suggest turning the process to a commercial scale(规模) may not be far off. And considering the 300 million tons of plastic into the environment every year, that day can't come soon enough. But it will come in time.
