Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic (经济的) reasons—why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?

    In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate (影响) its surroundings too much, it often improves the attractiveness of the area.

    It is true that there are examples of new buildings which have spoilt (破坏) the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative(保守的)and do not like change.

Although we have to respect people's feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move things forward . If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different , even though that might be the more risky choice.

    Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.

    “I would never have said to my mom, 'Hey, the new Weezer album is really great. How do you like it?'” says Ballmer. “There was just a complete gap in taste.”

    Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.

    Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.

    No wonder greeting cards today carry the message, “To my mother, my best friend.”

    But family experts warn that the new equality can also result in less respect for parents. “There's still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College. “In the middle of that change, there is a lot of confusion among parents.”

    Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.

    “My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side,” explains Mr. Ballmer. “It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”

    At the age of seven, while his friends were spending their allowances on things like candy and toys, Jose Adolfo Quisocola was busy saving money for basic purchases. To try to get his peers（同龄人） to do the same, the boy from Peru came up with the idea of an eco-bank, the Bartselana

    Student Bank, which allows kids of all ages to become financially independent while also helping the environment.

    Set up in 2012, the bank is the world's first bank for kids. To become a member, a kid has to bring in at least 5 kilograms of solid waste and set a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram of recyclables on a monthly basis and observe other requirements, such as attending financial education and environmental management workshops.

    The waste accumulated is sold to local recycling companies, who, thanks to Jose's efforts, pay a higher-than-market rate for everything brought in by the bank members. The money received is placed in the personal account where they collect until the savings goal is reached. The account holder can then withdraw the money, or choose to leave it and continue to grow for a bigger target. “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project,” Jose recalls, “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school headmaster and an assistant in my class.”

    The boy's efforts paid off, and by 2013, the bank had over 200 members, who brought in one ton of recyclable waste. Today, the eco-bank, which now has the support of several local institutions, boasts ten educational centers. They are designed to teach the over 3,000 students, aged 10 to 18, to become financially independent, use their money wisely, and help the environment.

    Not surprisingly, Jose's efforts have earned him several national and international awards. On November 20, 2018, Jose won Children's Climate Prize, which comes with a medal and $5,500 in prize money and is given to a child or youth who has accomplished an extraordinary achievement for the climate or environment.

    If plastic had been invented when the Pilgrims sailed from Plymouth, England, to North America-and their Mayflower had been stocked with bottled water and plastic- wrapped snacks, their plastic waste would likely still be around four centuries later. Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world's oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us.

    Because plastic wasn't invented until the late 19th century, and its production only really took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a surprising 6.3 billion tons never made it to a recycling bin-the figure that shocked the scientists who published the numbers in 2017.

    No one knows how much unrecycled plastic waste ends up in the ocean, the earth's last sink. In 2015, Jenna Jam beck a University of Georgia engineering professor, caught everyone's attention with a rough estimate between 5.3 million and 14 million tons of plastic waste each year just come from coastal regions.

    Meanwhile, ocean plastic is estimated to kill millions of marine(海洋的）animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplas-tics, the bits smaller than one-fifth of an inch across.

    "This isn't a problem where we don't know what the solution is, "says Ted Siegler, a Vermont resource economist who has spent more than 25 years working with developing nations on garbage." We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. "It's a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.

    When we found him, he was a sorry sight. His clothes were torn, his hands bleeding. Before we reached him, we saw him fall. He lay a moment. Then he pulled himself to his feet, walked unsteadily a few yards through the woods and fell again. After we got him out, we went back to find the gun that he had thrown down. His tracks showed that for two days he had circled in the forest, within 200 yards of the road. His senses were so dulled by fear and tiredness that he did not hear the cars going by or see the lights at night. We found him just in time.

    This man, like others before him, had simply been frightened when he knew he was lost. What had been a near disaster might have turned out as only a pleasant walk, if he had made a few preparations before he stepped from the highway or off a known path.

    Whatever sense of direction that a man may have, it's still largely a question of observation. A skilled woodsman always keeps an eye on his surroundings. He notes the shape of a mountain, the direction water flows through a swamp, and the way a tree leans across a path. With these in mind, he is still likely to turn around many times, but he is seldom lost.

    There are exceptions, of course, and once in a while a man does come across some strange problem that puts him into the “lost” situation. A rainstorm may catch him without a compass in his pocket. Darkness may find him in a rough area, where travel is dangerous without a light.

    When this happens, the normal first reaction is the fear of being laughed at as a result of his poor knowledge in the woods. He may also be concerned about the inconvenience that he will cause his friends when he doesn't show up. This false pride may lead him to keep on the move in a false effort to find his way against all difficulties.

    The person who thinks ahead is seldom in great danger. He'll be safe if he observes carefully, thinks ahead, and remains calm.

    The blooming of social media and interactive smartphone-based apps has proved that e-marketing is an unchangeable trend. In the case of China, the latest battlefield is beauty camera apps, which have become an overnight hit in the West.

    ⒈MeituPic

    Developed by the Xiamen-based Meitu Inc MeituPic is the company's flagship beauty camera app and was the first to become a big hit among Western users. The app has drawn some 456 million users, who use it to post more than 6 billion photos every month.

    In addition to MeituPic, Meitu Inc has developed a series of beauty camera apps such as Beauty Plus, Poster Labs and Meipai, each specializing in facial feature improvement, video editing and many other features.

    ⒉Pitu

    Tian Tian Pi Tu, is a beauty app developed by China's Internet giant Tencent. Similar to other photo-editing apps, Pitu offers a number of beautifying filters, blemish(瑕疵) removing tools and virtual makeup choices for users to choose from.

    Launched in 2014, Pitu has accumulated 106 million monthly active users (MAUs). While the number is not as impressive as that of Meitu's apps, some argue that the user base of Tencent's gaming products and chat applications, such as QQ and WeChat, gives Pitu great potential for further growth. According to Chinese app watchers, Pitu's target audience is younger and more individualized than that of MeituPic. 80 percent of Pitu's users are younger than 25, giving the app more room to try out more new features.

    ⒊FaceU

    In contrast with most other beauty apps, FaceU, focuses more on the social feature, encouraging users to video chat with friends and even strangers while playing with its fun stickers (贴纸) — and the strategy is undoubtedly working. Launched in 2016, the app, which mainly targets female users between 15 and 35, has twice made it onto the Apple store's Chart for top apps.
