I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签 ) everything. I always, looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

    War broke out one evening. Kate came into the room. ,Soon, I heard her screaming, "Take your shoes away! Why under my bed!" Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

    The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬 ) under her covers, sobbing.

    Obviously, that was something she should not go through phone. All of a sudden ,a warm feeling of sympathy rose up in my heart,

    Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't noticed Kate had sat up.

    She was watching, her tears dried and her expression one of disbelief. Then, she reached out her  hands to grasp mine. I looked up into her eyes. She smiled at me. "Thanks."

    Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to living together: giving in, cleaning up and holding on.

    When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.

    These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. "Boys who worked in the home or community gained competence（能力）and came to feel they were worthwhile members of society, " said George Vaillant, the psychologist（心理学家）who made the discovery. "And because they felt good about themselves, others felt good about them."

    Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31and 47. Under Vaillant, the researchers compared the men's mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

    The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.

    Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings（基础）of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, "One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work."

Internet time tied to teen depression(抑郁) symptoms

    Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, a new study finds.

    The findings, reported in the journal of Pediatrics, do not mean that the Internet is to blame. For one, teens in the study who spent no time online were also at increased risk of depression symptoms. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals that a teenager is having a hard time.

    For the study, Dr. Pierre-Andre Michaud and his colleagues at the University of Lausanne, Switzerland, surveyed 7,200 individuals aged 16 to 20 about their Internet use.

    Those who were online more than two hours per day were considered "heavy" Internet users, while those online anywhere from several times per week to two hours per day were considered "regular" users.

    The teenagers also answered a number of health-related questions, including some standard questions about "depressive tendencies" that gauge(判定) how often a person feels sad or hopeless. Compared with regular Internet users, the study found, kids who were heavy users or non-users were more likely to be depressed or very depressed.

    Among male teens, heavy users and non-users were both around one-third more likely to have a high depression score, compared to "regular" users. Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

    That was with factors like family income and any chronic health problems taken into account.

    Since teenagers typically go online to contact with friends, the researchers speculate(推测) that those who are never online may be more socially isolated.

    Stephen Hawking was a famous physicist. He was born in 1942. He died at his home on March 14h, 2018 in Cambridge, Britain.
    As one of the well-known physicists on space and time in the world, Hawking devoted his whole life to discovering the secrets of the universe, and he is called the King of the Universe. Since he was 21 years old, Hawking had been badly ill, but he didn't give up his hope of living. He went on to study at Cambridge University after graduating from Oxford University. In 1965, he got a doctor's degree. Then he worked as a professor at Cambridge University.

    Hawking was known for his work with black holes. He also wrote several popular science books. Although he didn't live as freely as others, he still felt he was happy and he was thankful to life. When Hawking was invited to China, he made speeches in some famous universities.

    From Stephen Hawking's whole life, we learn that no matter how bad life is, we should not lose hope. As he once said," Life is not fair, you just have to do the best you can in your own situation."

    Carrots are grown on farms and in family gardens throughout the world. Carrots are easy to raise and easy to harvest. They taste good.

    When people think of carrots, they usually picture in their minds a vegetable that is long, thin and orange in colour. But carrots come in many different sizes and shapes. And not all carrots are orange. For the best results, carrots should be grown in sandy soil that does not hold water for a long time. The soil also should have no rocks. To prepare your carrot garden, dig up the soil, loosen it and turn it over. Then, mix in some plant material or animal fertilizer. Weather, soil conditions and age will affect the way carrots taste. Experts say warm days, cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.

    Carrots need time to develop their full sugar content. This gives them their taste. But carrots loose their sweetness if you wait too long to remove them from the ground. The best way to judge if a carrot is ready to be harvested is by its colour. Usually, the brighter the colour, the better the taste.

    Carrots are prepared and eaten in many different ways. They are cut in thin pieces and added to other vegetables. They are cooked by themselves or added to stews. Or, once they are washed, they are eaten just as they come out of the ground.

    Most Americans see their pets as family members, surveys show. Those with dogs are more likely to call themselves pet "parents" than pet "owners". There are more of these parents than ever. In big cities such as San Francisco and Seattle,(owned) dogs outnumber children.

    The ways in which companies are profiting from the trend are also becoming various. Kinds of dog food and various pet mattresses (垫子) are always in hot sale. And it is not surprising that, for pets, Americans spent more than $400 million only on Halloween costumes this year. Overall, annual spending on pet food and products in America has risen by around 40% over the past ten years.

    Now a pack of startups have sensed a fresh opportunity.

    Much as Airbnb has offered travelers another choice instead of staying in a hotel, two firms, Recover and DogVacay, want to give pet owners an alternative to kennels (养狗场) when away from home. The cost is around $30 a night, with the majority of that going to the sitter, who takes care of the dog, and around a fifth to the company﹣much less than you would spend to check your dog into a kennel.

    The other big sellingpoint is that pets will receive better treatment. There are ways, apparently, to vet (审查) dog hosts to the real pet lovers: only around 15% of those who apply to serve as sitters are passed. Besides offering more attention and room, Rover has launched a feature that helps customers to see how far their dog has been walked via the GPS in the host's phone. Like Airbnb, both DogVacay and Recover insure stays against accidents.

    Another advantage of the model is that consumers often use dog-sitting services many times a year, and they tend to be loyal. That has helped DogVacay and Recover attract a lot of money﹣around $140 million between them.

    But firms that connect pets with hosts will face great competition as they try to go global. Companies offering homestays for dog rapidly appear in many different countries, including Australia, Brazil and Britain. And unlike Airbnb, which pulls in customers thanks to its presence in lots of markets that people want to travel to, the network effect for services like DogVacay is local.

    Despite having predicted the trend early, such firms may never achieve the same scale as an Airbnb. But then no one ever said it was easy to be top dog.
