Dear Alfred,

        I want to tell you how important your help is to my life.

        Growing up, I had people telling me I was too slow, though, with an IQ of 150 at 17, I'm anything but stupid. The fact was that I was found to have ADIID(注意力缺陷多动障碍). Anxious all the time, I was unable to keep focused for more than an hour at a time.

        However, when something did interest me, I could become absorbed. In highs chool, I became curious about the computer, and built my first website.Moreover, I completed the senior course of Computer Basics, plus five relevantpre-college courses.

        While I was exploring my curiosity, my disease got worse.I wanted to go to college after high school, but couldn't. So, I waskilling my time at home until June 2012 when I discovered the online computercourses of your training center.

Since then, I have takencourses like Data Science and Advanced Mathematics. Currently, I'm learning yourProbability course. I have hundreds of printer paper, covered in self-writtennotes from your video. This has given me a purpose.

        Last year, I spent all my timelooking for a job where, without dealing with the public, I could work alone,but still have a team to talk to. Luckily, I discovered the job—DataAnalyst—this month and have been going full steam ahead. I want to prove that Ican teach myself a respectful profession, without going to college, and be justas good as, if not better than, my competitors.

Thank you. You've given me hopethat I can follow my heart. For the first time, I feel good about myself because I'm doing something, notbecause someone told me I was doing well. I feel whole.

This is why you're saving my life.

Yours,

Tanis

    You never played the video dance game? Now such games are used to help lose weight!

    Like many other teenage boys, Jones loves sports. But at 5 feet, 175 pounds, he found his weight in trouble. His doctor wanted him to lose 50 pounds so that he may be a good football game player by the end of the summer.

    Jones chose the popular Dance Revolution video game at home to increase his activity. He had lost about 10 pounds by changing his diet. Now, after two weeks' playing the game, he has lost another 10!

    A health study is being done by an insurance company. The company hopes that the game will lead to better health and lower costs. “Obesity claims last year cost us $ 77 million. We have to cut those costs,” said a member of the insurance group. The company provides a game console (游戏主机), a dance mat and software for the six-month, $ 60,000 study.

    The study is more than a commercial thing of an insurance company. It is widely supported by physical education and health professionals.

    In West Virginia, 43% of the nearly 6,000 children examined for heart disease risk were considered over-weighted; more than 25% were too fat. “We are in a crisis of childhood obesity not only in West Virginia but in America,” said a researcher.

    Researchers are now looking at the potential for improving effects by using the game. A teacher in West Virginia has been using the video games in her classes since last fall. She reported that the game does improve heart health as well as eye-hand coordination (协调能力), and her students take the video game as a great alternative to jumping rope or ball games.

    The US Education Department is putting the game in 20 schools to control childhood obesity. Well, are you going to try such to dance away your extra weight?

Dearest darling girl,

    Today is the beginning of the next stage in your life. We head off to your new home at Stanford. Where do I start in telling you how proud I feel to be called Mummy by you? We've laughed at how you burst into this world with a scowl on your face, how determined you have always been right from feeding yourself to making big decisions for your life. There were days during your illness that I wasn't sure you had the will to make it. Telling you that you needed to want to get better was the hardest and yet the greatest day. From that day you took responsibility and decided you wanted to beat anorexia（厌食症）．

    I don't think I've ever felt so proud of you as when you came home to say that you wanted to go to West Africa between school and university. You chose to go alone, and to raise the money yourself. You have such strength of character and determination. It is at times hard to believe that you are only 18. You experienced something in that month that few dare experience in a lifetime.

    So, Viv, here are my words of wisdom to you as you start your next big adventure. The world is a beautiful place but often a few things can make it seem difficult. God's temple is made of love. It's man's temple that is built of stones. Open your heart to goodness and never ever let negative people or thoughts take hold of you. As Minor Myers put it, "Go into the world and do we'll. But more importantly, go into the world and do good:'

    It is true that with every passing day, I will grow older and weaker. A day may come when I will become forgetful. But even then, you with your bright smile, will light up my heart.

Your Alo

    According to the Associated Press (AP), a Chinese scientist claims he successfully created the world's first genetically-edited babies.

    Chinese researcher He Jiankui, a research professor at China's Southern University of Science and Technology in Shenzhen, said he had edited DNA of twin girls born a few weeks ago. ①

    He's claims were immediately criticized by some scientists as unsafe and unethical. This kind of gene editing is forbidden in the United States and many other countries. ②Such changes to a person's DNA can pass to future generations and risk harming other genes.

    In interviews, He Jiankui defended his work. He said he had performed the gene editing to help protect the babies from future infection of HIV, the virus responsible for the disease AIDS. He said the process had “worked safely” and the twin girls were “as healthy as any other babies.” He told the AP he felt a strong responsibility “not just to make a first, but also to make an example” for future research. “Society will decide what to do next,” he said.

    When He's claims became public, the university made a statement saying his work had “seriously went against academic ethics and standards.” University officials said they had no knowledge of his research and had looked into the case. ③

    China's National Health Commission was “highly concerned” about the claims and ordered local health officials “to immediately look into” He's activity. “We have to be responsible for the people's health and will act on this according to the law,” the commission said.

    Scientists discovered in recent years a new way to edit genes that make up a person's DNA throughout the body. The tool, called CRISPR-cas9, makes it possible to change DNA to supply a needed gene or take one away that is causing problems. So far the tool has only been used on adults to treat deadly diseases, and the changes only affected that person.

    ④Kiran Musunuru, a scientist from University of Pennsylvania, told the AP that if such an experiment had been carried out on human beings, it could not be “morally or ethically reasonable.” Julian Savulescu, a medical ethics expert at Britain's University of Oxford, agreed. “If true, this experiment may cause disasters,” he told Reuters.

    However, one well-known geneticist, Harvard University's George Church, defended the attempt to edit genes to prevent infections of HIV. He told the AP that since HIV is “a major and growing public health threat” he finds such experiments “valuable.”

    What do you remember about your life before you were three? Few people can remember anything that happened to them in their early years. Adults' memories of the next few years also tend to be unclear. Most people remember only a few events—usually ones that were meaningful and distinctive, such as being hospitalized or the birth of a new baby.

    How might this inability to recall early experiences be explained? The passage of time does not account for it; adults have excellent recognition of pictures of people who attended high school with them 35 years earlier. Another seemingly reasonable explanation—that infants do not form enduring memories at this point in development—also is incorrect. Children two and a half to three years old remember experiences that occurred in their first year, and eleven month olds remember some events a year later.

    However, three other explanations seem more promising. One involves physiological changes relevant to memory. Maturation of the frontal lobes (额叶) of the brain continues throughout early childhood, and this part of the brain may be critical for remembering particular episodes in ways that can be recalled later. Demonstrations of infants' and very young children's long-term memory have involved their repeating motor activities that they had seen or done earlier, such as reaching in the dark for objects, putting a bottle in a doll's mouth, or pulling apart two pieces of a toy. The brain's level of physiological maturation may support these types of memories, but not ones depending on clear verbal descriptions.

    A second explanation involves the influence of the social world on children's language use. Hearing and telling stories about events may help children store information in ways that will endure into later childhood and adulthood. Through hearing stories with a clear beginning, middle, and ending children may learn to take out the idea of events in ways that they will be able to describe many years later. Consistent with this view parents and children increasingly engage in discussions of past events when children are about three years old. However, hearing such stories is not sufficient for younger children to form enduring memories. Telling such stories to two year olds does not seem to produce long-lasting verbalizable memories.

    A third likely explanation for infantile memory loss involves mismatch between the ways in which infants encode information and the ways in which older children and adults recall it. Whether people can remember an event depends critically on the fit between the way in which they earlier encoded the information and the way in which they later attempt to recall it. The better the person is able to reconstruct the perspective from which the material was encoded, the more likely that recall will be successful.

    As the old saying goes, "Don't judge a book by its cover." And neither should we judge movie stars by their ages. At just 21, Elle Fanning made history by becoming the youngest jury (评审团) member at the Cannes Film Festival. This year it lasted from May 14th to May 25th. "I was in complete shock when I got that phone call and that question if I wanted to be a member of the Cannes Jury," Fanning said during a press conference.

    As it turned out, it not only shocked the US actress, but also brought criticism from those who believed Fanning was too young compared to other veterans in the industry. But Fanning's acting experience was in fact a good argument for her jury membership. In fact, Fanning has been a Hollywood fixture for longer than you realize.

    The 21­year­old has been in many big productions. She began acting in I Am Sam at age 2. With lead roles in movies like Super 8, We Bought a Zoo and Maleficent under her belt (取得成功), she's appeared in 60 projects and is one of Hollywood's hottest young stars. Fanning's devotion to work numbers her among the few former child stars who continue to act as adults.

    In her latest movie Teen Spirit, which hit US cinemas last month, Fanning plays a pop singer. Since she had no singing experience, Fanning had to work with Grammy­winning music producer Marius de Vries for three months before the filming started. "I would go to his apartment and sing through all the songs every day," she said. "He videoed me and recorded me singing everything and made me watch it back again and again to improve my skills."

    With such rich acting experience and devotion to her art, "Fanning certainly was able to represent a new class in film" at the Cannes Film Festival.
