    Nowadays, the Internet is usually one of the first places a lonely heart turns to as the following story shows.    

    A 63-year-old retired woman in Zhengzhou, made headlines two days after she posted an advertisement on her Wechat(微信) page, in which she said she wanted to find a young female companion for a trip to Sanya, China's Southern Hainan island, a local newspaper Dahe Daily reported. In the advertisement, the Chinese dama (Chinese term for middle-aged and elderly women) surnamed (a person's last name) Li said she is in good health, and she was particularly looking forward to a sea trip this winter.

    "I have a daughter who works in Canada, and I don't want to disturb her. My husband rarely has time to travel with me. But I'm afraid of traveling alone, so I am looking for a sweet, happy young woman, aged between 19 and 25 to travel with me. Hope she could chat with me, take photos with me."

    At the end of the advertisement, Dama Li showed her sincerity by saying she would be responsible for all the costs of the trip, including accommodation(膳宿) and air tickets, plus an iPhone 7 as a gift. Dama Li told Dahe Daily that she did not expect her advertisement to receive so much attention. "My phone keeps buzzing all the time. "However, some people question the truth of Li's advertisement. They say it might be organized by travel agencies aiming to promote(促进，推销) Sanya tourism, or even served as a promotional advertisement for real estate（房地产） on the island. Li denied those doubts and said all she wants is just to find a sweet "daughter".

    But Li's advertisement for a daughter has also received as many online mockeries(嘲笑) as positive feedback.

    The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environment­friendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of high­tech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.

    Among them，there are hydroelectric­powered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.

    Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panel­fitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.

    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.

Why College Is Not Home

    The college years are supposed to be a time for important growth in autonomy(自主性) and the development of adult identity. However, now they are becoming an extended period of adolescence, during which many of today's students are not shouldered with adult responsibilities.

    For previous generations, college was a decisive break from parental control; guidance and support needed to come from people of the same age and from within. In the past two decades, however, continued connection with and dependence on family, thanks to cell phones, email and social media, have increased significantly. Some parents go so far as to help with coursework. Instead of promoting the idea of college as a passage from the shelter of the family to autonomy and adult responsibility, universities have given in to the idea that they should provide the same environment as that of the home.

    To prepare for increased autonomy and responsibility, college needs to be a time of exploration and experimentation. This process involves "trying on" new ways of thinking about oneself both intellectually(在思维方面)and personally. While we should provide "safe spaces" within colleges, we must also make it safe to express opinions and challenge majority views. Intellectual growth and flexibility are fostered by strict debate and questioning.

    Learning to deal with the social world is equally important. Because a college community(群体) differs from the family, many students will struggle to find a sense of belonging. If students rely on administrators to regulate their social behavior and thinking pattern, they are not facing the challenge of finding an identity within a larger and complex community.

    Moreover, the tendency for universities to monitor and shape student behavior runs up against another characteristic of young adults: the response to being controlled by their elders. If acceptable social behavior is too strictly defined(规定) and controlled, the insensitive or aggressive behavior that administrators are seeking to minimize may actually be encouraged.

    It is not surprising that young people are likely to burst out, particularly when there are reasons to do so. Our generation once joined hands and stood firm at times of national emergency. What is lacking today is the conflict between adolescents' desire for autonomy and their understanding of an unsafe world. Therefore, there is the desire for their dorms to be replacement homes and not places to experience intellectual growth.

    Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.

    I've been really lucky this year. Not only did I have the opportunity to live in France, but I was able to see some other countries with my girlfriend. Now she is studying in Essen, a large city in Western Germany. I recently went to stay with her—it was my first visit to Germany! Essen is a very large city. It has all the conveniences of any large city so I felt immediately at home. I loved the variety of shops, restaurants, shopping malls, cocktail bars, nightclubs, parks and even a lake. There is also a city­wide network of trams, which makes getting around a piece of cake!

    I found the people to be really friendly, and most Germans speak very good English which made life easy for me. I was surprised by the casual attitude to alcohol in Germany, where it seems normal for people to drink beer on the street, or on the tram. My girlfriend and I visited two famous local cities, Düsseldorf and Cologne, which are both on the Rhine River. Düsseldorf is an urban metropolis with a great variety of restaurants. We took a boat tour on the river and went up the Rhine Tower, a really tall building which offers great views across the city. Cologne, as you might know, is world-famous for its perfumes. The cathedral there is an unmissable landmark. We made the effort to climb to the top of one of the cathedral's towers. The spiral (螺旋的) stairs seemed endless, but it was worthwhile for the impressive sights from the top.

    We also went in a cable car over the river and tasted a German delicacy called "Spaghettieis" which is ice cream with strawberry sauce! I also got to try the famous German sausage. I must admit, I really enjoyed the food! The only disappointment was the grey and rainy weather, which proves that Britain does not have the worst weather in Europe!

    The Chinese invented paper in 105 A. D. They mixed the bark of a tree and rags (破布) with water, put a screen into the mixture, and lifted out a thin piece of wet paper. They dried the paper in the sun.

    The Chinese kept their secret of how to make paper until a war with Muslims in the ninth century. The art of papermaking soon spread throughout the Muslim world.

    The Mayan Indians in Central America and Pacific Islanders also discovered how to make paper, but their knowledge never spread to the rest of the world.

    For centuries, all paper was made by hand. Rags were the main material. Then a French scientist discovered that people could make paper from wood, too. Finally, in the eighteenth century, a Frenchman invented a machine to make paper from wood.
