Hello. I'm Jan from Mrs. Lake's class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt（收养） a highway.

    Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road. This sign lets drivers know who is keeping that area of the road clean.

    The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

    We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake's room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we'll try to pick an area to adopt and clean.

    I look forward to seeing you at the meeting. Remember to keep our roads clean!

    The science fiction type of entertainment is considered by mot to be fathered by Jules Verne (A Journey to the Center of the Earth and Twenty Thousand Leagues Under the Sea) and H. G. Wells (The Time Machine and The War of the Worlds). Sei-Fi, as it is commonly shortened, is a fictional story in which science and technology have a significant influence on the characters and plot. Many such works are guesswork about what the future holds and how scientific findings and technological advances will shape humankind.

    Writing in the late 1800s, Jules Verne was remarkably successful in his 10 guesses about future technologies of air conditioning, automobiles, the Internet, television, and underwater, air, and space travel. Unbelievably, of all places from which to choose, Jules Verne guessed Tampa, Florida, USA as the launching site of the first project to the Moon, which was only 200 kilometers away from the actual 1969 location at Cape Canaveral, Florida.

    One of the best-known science fiction books is Nineteen Eighty-Four by George Orwell. Published in 1949, it was not meant as a prediction, but as a warning: Orwell was describing what he saw as the outcome of the ideas, trends, and emerging technologies of his time. Many invented terms from this novel have become common in everyday use, such as “big brother” and “doublethink”. Even the author's name has been made into an adjective—Orwellian—and has become a warning descriptor for situations where privacy is lost and the individual has no power and is completely controlled by the government. Nineteen Eighty-Four was translated into sixty-five languages within five years of its publication, setting a record that still stands.

    What helps bring science fiction into being is usually a new discovery or innovation. The author creates an analysis of the potential influence and consequences and then wraps it in a pleasant story. For example, the beginning of space exploration was followed a few years later by the Star Trek television program and movie series. The science fiction author's self-determined role is search the world of future possibilities upon the road which we are traveling.

    Lisa Pina never thought she would need the fire safety training she received during her apprenticeship(学徒期)as a union painter and dry waller(筑墙工). On Friday morning, she was thanking God she had it.

    On Thursday night, while Pina was babysitting her granddaughter, nephew and two nieces in her sister's apartment, she smelled smoke and realized the apartment building was on fire. When her 4-year-old granddaughter Ilean Garcia began saying, “We're going to die, ”she knew she had to act.Pina,39, first sealed the door, and then told all four children to get on the floor. After calling 911, she told the children to start singing and promised them all treats as soon as they reached safety. “I said, ‘OK, we're going to lie down and we're all going to play a game,'” Pina said. “We all started singing our ABCs and 123s.I was just trying to make it fun.” Pina patiently waited, and a few minutes later, Riverside County sheriff's deputies (治安官的助手) arrived. Pina, Ilean,8yearold Gabriel Parga,5-year-old Aubreyana Parga and 4-year-old Meriyah Parga were all trapped on the second floor as flames filled the first story.  Pina did the only thing she could. She opened the window and dropped the children, one-by-one, into the arms of the sheriff's deputies about 15 to 20 feet below. “I just needed to keep the kids calm so they wouldn't be afraid，”Pina said.“I was deathly afraid inside，but I couldn't let them know that.”[Not long after dropping the children out of the window, firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke, but nobody was seriously injured.

    From now, if all goes well, a high-tech spacecraft will land in the South Pole of the moon. There, it will drill 66 feet down into the surface(表面) and collect samples of the mantle(地幔样本) to bring back to the earth.

    But before it leaves, it will have a two-part time capsule(时光胶囊): a public part, full of the Earth's history, and a private part, full of digital(数码的) memory boxes created by individuals(个人). These memory boxes can hold digital files — records of family trees, videos or actual DNA in the form of human hair. Not everyone can have a digital memory box, though. The boxes are only delivered for the people who donate the money to the project.

    The project, called Lunar Mission One, has already raised more than half of its ￡600,000 goal since its launch(启动) just a few days ago. The founders thought that it would succeed because of the attraction of both exploring the moon surface and leaving a time capsule behind. The mission was a technical action, but it was also an emotional one, bringing the excitement of knowing that something humans built on the Earth reached somewhere else in space.

    Still, it does seem risky(冒险的) for a person to donate￡60 to keep a digital memory box for a project that won't come true until 2024. What if the project never takes off? What if the technology isn't good enough? What if those digital memory boxes break on the moon's surface? And how will anybody ever even know if that happens? Ian Crawford, a professor at Birkbeck College in London and scientific advisor to the mission, says it is not necessary to worry about these. The plan to leave a time capsule on the moon isn't really about physically leaving something on the moon — it's more an opportunity to encourage people's interest in space.

    Britain and France are two important countries in Europe. They are neighbors, separated only by the 20-mile seaway of the English Channel. And for most of the time that the two countries have existed, the French and the British have been rivals or even enemies. One conflict between the two countries lasted over 100 years, and the British and French were at war through the 18th century.

    There is no fighting now, of course. But there is still a strong sense of rivalry (敌对) between the two nations. That's why a recent survey in the UK caused a major shock.

It revealed (揭露) that one third of the British people would like to live in France. It also showed that twenty-one percent of British people would actually prefer to have been born in France.

    Many reasons were given. France has a better climate and a more relaxed lifestyle, with some of the longest holidays in Europe. It is thought to have better public services in every area from health to transport. People in France work shorter hours and enjoy longer vacations. And think of the food and wine!

    Estimates (估计) of the numbers of Britons living in France range from 100,000 to half a million. But it is not one-way traffic. Around 15,000 French people per year come to live in Britain, mainly settling in London. They are attracted by higher pay in Britain, lower taxes, a more dynamic lifestyle. Now it seems that people can go to the place that suits them best.
