Ask any kid, and you'll likely hear that time spent with friends is the coolest and most important part of the school day. Educators, as well, acknowledge that making friends is one of the most valuable things children do as they learn and grow. But many parents are perplexed by their children's social lives, wondering how to help their kids cope with the challenges, heartbreaks, and the joys of making friends, losing them, and making friends again.

    “Friendships help children gradually learn to be independent, contributing members of a community and it's just as important as their academic growth” notes Diane Levin, Ph.D., author of “Remote Control Childhood.” However, it's a slow process. There are many social skills to learn, which advance with age and experience, trial and error, and experiencing the satisfaction that comes from contributing to an ongoing friendship.”

    “Friendship starts as soon as children can crawl off their parents' laps over to another child,” adds Michael Thompson, Ph.D., co-author of her life with you to her life with her friends. but who their friends are, how they interact with them, and how popular they are, is something parents have only limited control over.”

    Experts on children's behavior say that problems like jealousies, breakups, bullying and teasing account for a big part of what parents, kids and teachers talk about, and what parents worry about.

    Get insights into how children's friendships develop and how parents can help, if needed, and find ways to determine if your child is at risk for serious social problems or simply suffering from real (but common) social challenges.

    The first person in the world to receive two facial transplants says he is feeling well, three months after his latest groundbreaking operation.

    Jerame Hamon had his first transplanted face removed last year after signs of rejection following a treatment with an antibiotic (抗生素) during a cold.

    The 43 year old remained in a hospital in Paris without a face for two months while a compatible donor was sought.

    He said: “The first face I accepted immediately. This time it's the same.”

    Mr. Hamon suffers from neurofibromatosis (多发性神经纤维瘤), a genetic condition that spoiled his face severely.

    His first transplant, in 2010, was a success, but he caught a common cold in 2015 and was given antibiotics. The drug was incompatible with the immunosuppressive (免疫制疫的) treatment he was having to prevent a rejection of the transplanted material.

    The first signs of rejection came in 2016 and last November, the face, suffering from the death of most of cells, had to be removed.

    Mr. Hamon lived without a face in a room at Georges-Pompidou hospital in Paris without being able to see, speak or hear until January, when a face donor was found and the second transplant carried out.

    To avoid further rejection, Mr. Hamon—dubbed “the man with three faces” by French media ―had special treatment to clean the blood prior to the transplant.

    His new face remains smooth and motionless, and his skull, skin and features are yet to be fully matched. But he is positive about his recovery.

    “If I hadn't accepted this new face it would have been terrible. It's a question of identity… But here we are, it's good, it's me,” he told AFP news agency from the hospital, where he is still recovering.

    The hours-long operation was led by Prof Laurent Lantieri, a specialist in hand and face transplants who carried out Mr. Hamon's initial surgery eight years ago.

    “Today, we know that a double transplant is practicable, it's no longer in the field of research,” he told Le Parisien newspaper.

    Anaesthetist Bernard Cholley said: “Anyone who loses their face and then has to wait for a possible and imagined transplant for an unknown length of time—that's something that nobody has ever had to go through here.”

    “I'm amazed by the courage of a patient who has been able to get through such a different experience.”

    The first face transplant was carried out in 2005 in northern France. Since then, some 40 operations have been performed around the world.

    "Iris scan (虹膜扫描), please," the bank's computer voice tells you . You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match—otherwise you won't be able to get your money.

    Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics( 生物测定学) a fast developing area of automatic personal identification technology . Basically, biometrics uses various ways to verify a person's identity, based on the individual's unique characteristics, including fingerprints, voices, irises, body heat patterns, facial images, handprints, signatures and so on.

    Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose or steal.

    The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone and the correct software. The software records a subject's voice and then compares it to a stored voice sample for identification purposes.

    For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.

    Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology, full facial scans, is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd.

    The potential of biometrics is exciting and encouraging. With continued development, testing, and application, current technologies will become even more effective in the future. Soon, the days of password and car keys will be gone. Just don't leave home without your fingerprints!

    Work started this week on next season's flu vaccine (疫苗), with experts working off forecasts about which types of the flu virus will be making the rounds. But don't expect any improvements. Flu experts are already admitting that most vaccines will give at best basic protection, because they're based on old-fashioned technology. It's not a new problem, but one that the slow-moving world of drug and vaccine production seems helpless to improve upon.

    Every flu vaccine is a cocktail, aimed at either three or four of the most common flu types. Flu vaccines must be recreated every year because flu viruses develop constantly in a process called antigenic drift. In February, global flu experts gather to trade notes on what viruses are circulating in different countries and to come to an agreement on which types the next vaccines should be made to target.

    In recent years, flu vaccines have been based on H1N1, H3N2 and either one or two types of influenza B virus. Each of these has a "reference" type, which is used to make seed virus. Producers add the seed types to eggs and incubate (孵) them as the virus grows. Then they purify the virus, and either weaken it or kill it to make a vaccine.

    Using eggs is a tricky (=difficult) and unpredictable process. Sometimes the virus doesn't grow well in eggs, which can mean less vaccine than expected. The result is a flu vaccine that doesn't offer much protection. "As long as we have eggs we are going to have this problem," said Scott Hensley, a flu virus expert, "The only solution is not to depend on eggs."

    Flu is a major killer. The 2017-2018 season has been a severe one, hitting the entire U. S. with widespread influenza infection (感染) at once for weeks on end, and killing 97 children so far. Against this threat, even a less satisfying flu vaccine will definitely help. "Even when you have these mismatches it will not prevent infection but likely prevent disease severity," said Hensley.

    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 meters, 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). The sides of the building aren't regular. So the building has an unusual shape. 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 moment the building is empty, but finally 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 shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians(埃及人)did that 4, 500 years ago.

    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 apartments and stay in the hotel. But the people living near the Shard are among the poorest in London. So the Shard seems a symbol of the division(分化)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.
