"If there is one thing I'm sure about, it is that m a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.

    The nature of what is news may change .What basically makes news is what affects our lives - the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though .It's already happening in areas that may directly affect our lives, like genetic（基因的） engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do - as we develop a better understanding of how the brain operates and what our feelings really are.

    It's quite possible that in the next century newspapers will be transmitted（传送）electronically from Fleet Street and printed out in our own home. In fact ,I'm pretty sure how it will happen m the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read sports and international news, etc.

    I think people have got it wrong when they talk about competition between the different media（媒体）．They actually feed off each other.  Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet. it's never really pleasant to read something just on a screen.

    A new American weather satellite could save more lives by better predicting extreme weather conditions. It will be in orbit(轨道）some 36,000 kilometers above Earth's surface. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.

    NOAA officials are calling the new satellite GOES-R. That is short for a much longer name—the Geostationary Operational Environmental Satellite-R Series. NOAA said GOES-R could improve the nation's ability to observe weather conditions and make weather predictions. It said the satellite's operation would lead to more exact and timely weather forecasts watches and warnings.

    The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year."

    "The next generation of weather satellites is finally here." said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most complicated Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more detail than any other NOAA satellite currently in operation. She believes this will make the United States an even stronger, more “Weather-Ready" nation.

    A NOAA statement said the greater detail will help improve the agency's study of ocean storms, as well as “the prediction and warnings of severe weather. "In addition, GOES-R will be able to provide improved rainfall estimates (预计), which will lead to more timely and detailed flood warning. The statement also said that GOES-R will give better estimates of wind strength, as well as better measurement of fog, ice or lightning strikes.

    Craig Fugate serves as administrator of the Federal Emergency Management Agency. He says that the GOES-R satellite will improve the ability of people and organizations across America to prepare for, and react to, weather-related disasters.

    Soaping up your hands may do more than just get rid of germs. It may wash away the inner confusion you feel right after being forced to make a choice between two appealing choices, according to a new study. The study builds on past research into a phenomenon known as “the Macbeth effect”.

    It turns out that Shakespeare was really onto something when he imagined lady Macbeth trying to clean her conscience（良心）by rubbing invisible bloodstains from her hands. A few years ago, scientists asked people to describe a past wrong act. If people were then given a chance to clean their hands, they later expressed less guilt than people who hadn't cleaned.

    This finding fascinated W. S. Lee, a researcher. “Anything from the past, any kind of negative emotional experiences, might be washed away,” says Lee.

He decided to test hand washing's effect on one kind of bad feeling: the tension we feel after being forced to choose between two attractive choices, because picking one choice makes us feel that we've lose the other. People usually try to calm this inner conflict by later exaggerating（夸大）the positive aspects of their choice.

    He had students rank 10 different music CDs. Then be offered students one CD as a gift. Some students then use liquid soap. Others only looked at the soap or sniffed（噢）it. “Actually, you do not need water and soap,” says Lee.

    Later, the students again had to rank all the music. People who didn't wash their hands had the normal response — they scored their take-home CD higher. Suggesting that they now saw it as even more attractive than before. But this wasn't true for the hand washers. They ranked the music about the same. “they feel no need at all to justify the choice,” say Lee.

    But the implications of it just aren't clear. Schwarz says it's too soon to know whether people should head for a sink after making a tough choice. He says washing may help decision-makers by cleaning away mental disorder, but perhaps if they don't go through the usual post-decision process of justifying their choice, they might feel more sorrow in the long run.

    Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.

    One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.

    Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.

    Homer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.

    Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.

    Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer's theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.

    According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.

    The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK's University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”

    As is often the case, however, there are others who find the theory less convincing. Cambridge University's paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It's only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.

    Traveling can be a fun way to gain life experiences, especially during Spring Break-a week-long school vacation in the United States. But what if you're a student and don't have enough money for a trip？Don't worry. Here are some useful suggestions.

    Save：This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead：Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

    Do your homework：No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly：Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups：Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

    Work as you go：Need more money to support your trip？Look for work in the places you visit.

    Go off the beaten path：Tourist sites may be expensive. You may want to rethink your trip and go to a less﹣known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things：The most important things to take are not always clothes.

Remember medicine in case you get sick, and snacks in case you cannot find a cheap restaurant.

    Use the Internet：The net can help to save money. Some useful websites include www.travelcity.corn, www.bargainslowestfare.corn and www.economictravelcity.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

For nearly two decades, a thin, sun-burnt postal worker could frequently be seen carrying packages along a dangcrous mountain trail in the Taihang Mountains.

The 10-kilometer-long route, which is between 20 centimeters and 1 meter wide, is known as the "cat road" by locals, meaning that it is so dangerous that only cats could walk on it. Whereas, Zhao Yuefang, a postal worker in Ewu township in Huguan county, Shanxi province, had to walk the route every day to deliver mail.

Every day at the crack of dawn, he would start his journey along the "cat road". From picking up the day's post to delivering it to villagers and returning along the same route, it took Zhao four days. During rainy and snowy seasons, the mountain road, part of which hugs the cliffs, would become slippery and dangerous. One day in the winter of 2003, the "cat road" was covered in thick snow and he slipped off the trail. Fortunately, he was able to stop his sharp descent by grabbing a tree branch and slowly managed to climb to safety.

By 2012, Zhao had walked more than 300,000 km and delivered over 800,000 pieces of mail. Born and raised in the deep mountains, Zhao truly understands the significance of mail deliveries to villagers. "They depend on the mail to keep in touch with the outside world," he said. "Their sheer joy written on their face while receiving any post struck me," he added.

In 2012, a 67-km-long tourist highway was built and gone were those days when Zhao risked his life to walk on the "cat road". But Zhao was even busier than before. "The number of packages I handle daily now exceeds the number I used to deal with in the past," said Zhao, adding that villagers are turning to online shopping and ordering more and more goods by post.
