London's newest skyscraper (摩天大楼)is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 metres, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better.

    The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire (尖顶)• He wanted the glass surfaces to reflect the sky and the city. The sides of the building aren't regular. So the building has an unusual shape. It looks like a very thin，sharp piece of broken glass. And that is how the building got the name: the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts (桅杆）of the ships that were once on the river Thames.

    The Shard has 87 floors. At the top, there is an observatory. At the moment the building is empty, but eventually there will be a five-star hotel. There will also be top quality restaurants, apartments and offices.

    Before building work began, a lot of people didn't want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its spire shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians did that 4,500 years ago. They also think the Shard is too big for London. It destroys the beauty of the city.

    Other critics don't like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive private apartments and stay in the hotel. But the people who live near the Shard are among the poorest in London. So the Shard seems a symbol of the division in society between the very rich and the poor.

    The Shard now dominates the London skyline. It is not certain, however, that ordinary London citizens will ever accept it as a valuable addition to the city.

    The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

    Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

    Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it, but it is mainly because such collection is unorganized”. Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

    The solution, says the report's author, Alan Hamilton, is to encourage local people to protect these plants. Ten projects studied by Plantlife in India, Pakistan, China, Nepal, Uganda and Kenya showed this method can succeed. In Uganda, the project has kept a sustainable supply of low-cost cancer treatments, and in China a public-run medicinal plant project has been created for the first time.”

    “Improving health, earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,” says Hamilton, “You have to pay attention to what people are interested in.”

Ghillean Prance, the former director of the Royal Botanic Gardens at Kew in London, agrees that medicinal plants are in need of protection. “Not nearly enough is being done,” he told New Scientist. “We are destroying the very plants that are of most use to us.”

    At the end of last summer my parents' house in Tunstall went up in flames. Several months on, we're still trying to find out exactly what happened, but my parents John and Carole were out when more than half the house was burned to the ground. What was left behind needed to be pulled down and most of the things that were not actually destroyed were so smoke-damaged that they would have to be thrown away.

My parents were both teachers and not the kind of people to fill their house with expensive furniture, so most of their belongings were memories—--including photos and the tracksuit(运动服) that Dad was given when he carried the Olympic torch (火炬). But what really upset me was not the loss of these things.

    Dad had an album(唱片) for every occasion. Once his car got broken into and he was more upset that his cassettes had been nicked(划伤) than about all the rest of the damage. So when I was considering doing something to help after the fire, I immediately thought about his music. We couldn't get the old photos back, but we could replace his CDs and records. Then I started a little page about my dad on the blogging site Tumblr.

    Within a few days, news of what had happened spread by word of mouth, and I was getting messages from friends I hadn't spoken to for years. I also heard from Dad's mates and even from people neither of us had ever met. Soon packages arrived from all over the country. I expected 100CDs if we were lucky, but his new collection would now run into the thousands!

    On Christmas Day, all the records, tapes and CDs were packed into a beautiful box, which of course, was for my dad. A lot of them came from his previous students and he was touched to realize what an effect he had had on their lives. Eventually , he told me, “What could have been a bad Christmas has been a very good one.”

    The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

    Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

    I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

    The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote.

    "You must properly respect what you are after and shoot it cleanly and on the animal's own territory(领地)。You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing - not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people."

    I can understand such beliefs, and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

    An “adulting conference” (AC)this week allowed Kentucky high school seniors the chance to learn how to change a tire, how to cook and other basic life skills—things that they may not have learned at home or in classes. A series of photos posted by Bullitt Central High School on social media shows students taking “adulting conference” are learning about personal finances, resumes and other essential skills at the event, which has been widely reported on the local and national news outlets.

    “I saw a Facebook post that parents passed around saying they needed a class in high school on taxes and cooking,” AC organizer Hardin told Louisville's WAVE 3 News. Those skills are taught at school theoretically, she said, but the event gave students a chance to fill in gaps in their knowledge.

    Students could choose to attend three workshops out of 11 total options, the school says. The workshops were held in cooperation with numerous community partners.

    Some young people have left home and graduated school without having those gaps filled, according to a report this week from CBS New York, which documented a trend of young people seeking outclasses to learn basic life skills.

    While attending a cooking class, 29-year-old Elena Toumaras told the station she's struggling with “simple things.”

    “I was so used to, when living at home, my mom always cooking,” she told the station.

    An“Adulting School” in Portland, Maine, aims to use a new online format to teach the youths skills like conflict resolution, sewing and appreciation for all, the station says.

    Students' financial literacy has been of particular concern to some experts, as financial education in schools has stagnated(停滞)in the U.S., with only 17 states requiring students to take classes in personal finance—a number that hasn't risen in years.

    “The majority of U.S. states are failing our students by declining to offer these fundamental courses which are critical to their financial stability and security later in life. And this will be changed.” Nan J. Morrison, president and CEO of the Council for Economic Education, told CNBC.

    Do you still use a power button(开机键)to open your smart phones or computers? You are out of fashion! Now most smart phones are using facial-recognition system(面部识别系统), and we already have machines that can know you from your fingers and your voice too. But some companies are still willing to invent other systems to "break" these systems, for example, the eye-recognition system. As is reported, you'll just have to look at the computers and machines, and this system will be able to tell you who you are by looking at your eyes, even when you are wearing glasses.

    Do you wonder if this system will work well? The answer is YES. All you need is just look at your machines. The eye scanner(扫描仪)is put in the cameras of your machines. The eye-recognition system is safer and easier than other systems. This is because everyone's eyes are different. Since the system works easily, you won't have to remember a group of code when you want to open your computer or take money out of a bank in the future. Eye-recognition system is better than other kinds of systems because your eyes don't change as you get older, and don't get dirty like hands or fingers. Even twins' eyes are not the same. So the eye-recognition system can be up to 94 percent correct, but it depends on how good the technology is. Some systems may only 51% right. In Britain, it was found that 91 percent of the people who had tried it said that they liked the idea of eye-recognition. So scientists think it will become more popular than other systems.

    The eye-recognition system has already been tested in shops in the USA, Britain, Spain, Italy and Turkey Soon it will become a popular way among public. In the future, your computer will be opened by looking at your eyes.
