As a boy, Charles Robert Darwin(达尔文) collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.

    His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin's interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin's great life.

    As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.

    Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin's great book “On the Origin of Species by Means of Natural Selection”(《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.

    Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.

    Dogs are wonderful companions all their own, but they can also help change your life so that you're more accepting of new friendships. A new study studied how dogs' brains responded to the human voice and found that “the human brain responds to dog emotions the same way it responds to human emotions” and that the dog's brain does the same.

    Dogs are pack animals, so in terms of pet ownership, your dog will prefer to stay with you rather than somewhere alone. Think about how this concept applies to friendship. People today are getting more and more used to spending time on social networking, email, and text. While all methods of communication are good, there is nothing like seeing your friends and hearing their voice. With good friends, sometimes a look explains everything, and you can only get this when you're together hanging out in person.

    Let's face it, dogs never hide their feeling. They let you know what they enjoy doing most, whether it is chasing a ball, going for a walk, or getting a treat. For people, it's harder to be open with your emotions. But in order to truly find a friend, you'll need to let go of your fears and put trust into your friends. The reality is that you'll never make everyone you meet happy one-hundred percent of the time, so if your friends and family think you're great, put aside the need to be liked by everyone.

    Dogs wait for you to come home and are so happy to see you again that they practically do a happy dance when you walk through the door. Friends, on the other hand, are sometimes so busy that even hearing from a friend becomes an unwelcome interruption. Rather than avoid calls or emails, make a point to talk to friends on a regular basis.

    Nearly 20 U.S. states have started carrying out former president Barack Obama's Clean Power Plan, which places limits on carbon dioxide emissions from power plants in an effort to reduce the impacts of climate change. The plan has been in legal limbo (边缘) for the past year. Yet scientists have now calculated another outcome of the policy: harm to crop yields (产量) if the plan is cancelled. Along with carbon pollution, coal-fired power plants spew (喷出) pollutants that form what we know as smog. The contribution of smog to increased rates of asthma (哮喘) and premature deaths was already known. The new research estimates the extent to which smog, under air-pollution policies-4n place before the Clean Power Plan, would limit production in 2020 of four major crops: corn, cotton, potatoes and soybeans.

    Led by environmental engineer Shannon L. Capps, now at Drexel University, the team also sketched the extent to which those crop production losses would reduce under three nationwide scenarios (方案). One improved the efficiency of individual power plants. Another modeled a policy similar to the Obama plan, setting state CO₂ emissions goals for the electricity department. A third established a tax on carbon emissions, under which emissions fell the most. But the greatest drop in smog-forming pollutants—and greatest gains in crop yields—came from policies such as the Clean Power Plan.

    Researchers calculated how well each scenario would reduce the potential productivity loss (PPL) of each crop. PPL is a projected value for 2020 and indicates how much crop growth would suffer because of smog. Scenario 2 most closely agrees with results expected from the Clean Power Plan.

    At least 12 other murders since 1997 have been linked to an addiction to violent video games. This year, the parents of a 14-year-old murder victim in the UK blamed the killer's addiction to the game Manhunt, causing a government review of legislation (立法) to protect children.

    But is there any scientific evidence that mere games can make children and young adults more aggressive, or possibly have the desire to murder? There is no doubt children are being exposed to more games violence than ever: around a quarter of all games released in the US contain some violence. And the violence is becoming more obvious as increases in computing power make the games look ever more realistic.

    Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to use weapons as second nature. Secondly, violent games provide repetitive aggressive experiences that are rewarded by more killing.

    Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, Craig Anderson of Iowa State University in Ames and his colleague Karen Dill found that people who played violent games were more likely to admit to aggressive behaviour, including attacks or robberies.

    Earlier this year, Krahe and her colleague Ingrid Miller reported a study of 13 to 14-year-old children. More than half had played games recommended only for over-18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Other authors in the same edition report that children who play violent games more likely to argue with teachers and fight with others.

    Experimental studies have also pointed out a possible link. In one, Anderson and Dill asked a group of students to play a violent game, Wolfenstein 3D, while another group played the non-violent Myst. Those who played the violent game were faster to react to aggressive words flashed on screen and appeared more aggressive.

    The issue is controversial, however. Jeffrey Goldstein, a psychologist at the University of Utrecht in the Netherlands and a consultant to some video games publishers, agrees that there is good evidence that children, who are exposed to violent media, including video games, are more aggressive. But he warns it might not be a simple case of cause and effect: aggressive kids might be most attracted to violent games.

    Most parents fear getting letters home from their children's school. They are usually informing them that their child is in big trouble. But ahead of the SATs exams next week, one school decided to send a letter of a different type.

    Bosses at Buckton Vale Primary School in Stalybridge sent letter to all pupils in the sixth grade to tell them how special and unique they are. The letter highlights all the natural skills and abilities the pupils have and everything that makes them "smart'' individuals.

    They are told how their laughter can brighten the darkest day and that the examiners do not know the pupils are kind, trustworthy and thoughtful.

    The letter, signed by the headmaster and two other teachers, has been put on the school's Facebook page and shared more than 9. 000 times with more than 7,000 likes.

    The letter reads, "Next week you will sit your SATs tests for maths, reading, spelling, grammar and punctuation. We know how hard you have worked, but there is something very important you must know. The SATs test does not assess all that makes each of you special and unique. The people who create these tests and score them do not know each of you in the way that we do and certainly not in the way your families do. "

    The letter goes on to say that the tests are not the most important thing in life, adding, "The scores you will get from this test will tell you something, but they will not tell you everything. There are many ways of being smart. You are smart!"

    The letter has been welcomed by many parents on Facebook. Lynn McPherson wrote, "That's great instilling (逐步灌输) hope, faith and belief. " And Mary Tilling said, "Every child school receive one of these. Brilliant. "
