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, 31 and 47. Under Vaillant, the researchers compared the men's mental-health scores with their boyhood-activity 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.”

    Spring and fall are usually thought to be enjoyable seasons. However, it is not always the case. {#blank#}1{#/blank#} It makes people suffer a lot from it.Why can't they find a cure（疗法）for the common cold?The answer is easy. There are actually hundreds of kinds of cold viruses（病毒） out there. You never know which one you will get.{#blank#}2{#/blank#}

    When a virus attacks your body, your body works hard to get rid of it.{#blank#}3{#/blank#} .You feel terrible because you can't breathe well, but your body is actually eating the virus.Your temperature goes up and you get a fever, but the heat of your body is killing the virus.You also have a runny nose to stop the virus from getting into your cells.You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

    {#blank#}4{#/blank#}.In China and some other countries, for example, some people might eat chicken soup to make themselves feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop various symptoms（症状）of colds.

There is one interesting thing to note-some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in your body longer because your body doesn't have a way to fight it and kill it. {#blank#}5{#/blank#}.There is a joke, however, on taking medicine when you have a cold.It goes like this: It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine. So you should trust the function of your body.

    The US will have a new president this fall. Voters will decide between the Democratic candidate (候选人), Hillary Clinton, and Donald Trump of the Republicans.

    But the voting is not a must for each person in the US. So quite a lot of people choose not to vote, especially the young generation. According to Fox News, one-in-five young voters between the ages of 18 and 35 said clearly that they wouldn't vote for either of the two candidates. Just 12 percent of voters aged 35-54, and only nine percent of voters aged 55 and older said the same thing.

    This is not only because young people don't like Clinton or Trump, according to the Fortune magazine. The truth is that they are traditionally less likely to vote than their parents.

    “Young people are not at an age in their life when they think politics or government has anything to do with them,” said Rodd Freitag, a political science professor at the University of Wisconsin-Eau Claire, US. “But for the older age groups, they have a home, they pay taxes (税), they care about schools and the community.”

    Many believe that the civic (公民的) education of an American youth is another reason why they don't vote.

    Students usually just do community services like cleaning the neighborhoods. This means they haven't learned how to link real life problems to politics through voting, according to Christopher Beem, a politics professor at the Pennsylvania State University.

    He said the country needs to help young people learn how to take part in politics and get them to see that they can make a difference.

    In my memory, winters always used to be really unpleasant. You had to dress like a bear just to keep warm when you went outside. You were often cold, wet and no more than one step away from the thin ice on the lake. If you worked over time and went home in the dark, you would arrive home to an ice-cold house. And that would mean turning on the heating and waiting.

    Fortunately, things don't have to be so challenging any more. Technology, engineering and design have developed, giving us new solutions to old problems. It means dealing with winter needn't be like skating on thin ice.

    With a smart thermostat(恒温器), our homes can be toasty when we need them to be. Many models go with smartphone APPs that allow you to regulate temperature from a distance, so we can warm up the house before we arrive home. According to techradar.com, a large technology news and reviews website, Tado's model has a voice control function, while the Nest “learns” your habits and heats the house for you.

    Clothes have been given an upgrade, too. Electronic heated jackets and trousers heat up when you turn them on. What better way to keep warm in the dead of winter? At the touch of a button, or through an APP on our phones, the clothes produce heat from materials placed inside. Many models offer three levels of heating which stay warm for over 12 hours.

    Finally, there is the headgear(头部装备) - Hats that have speakers which are included in the cloth using Bluetooth technology, so we can listen to our favourite music or, in some cases, have a phone call using the in-built microphone. All while keeping the head warm and avoiding coldness.

    For many, the thought of winter used to be enough to make their blood run cold. But using technology, life needn't freeze up. There's no reason why winter can't be really, really cool.

    "Hope has proved a powerful predictor of outcome in every study we've done so far," said Dr. Snyder, a psychologist.

    In research with 3,920 college students, Dr. Snyder found that the level of hope among freshmen at the beginning of their first term was a more accurate predictor of their college grades than were their S.A.T. scores or their grade point averages in high school. "Students with high hope set themselves higher goals and know how to work to attain them," Dr. Snyder said. "When you compare students with equal learning ability and past school achievements, what sets them apart is hope."

    In seeking a way to assess hope scientifically, Dr. Snyder went beyond the usual belief that hope is merely the sense that everything will turn out all right. "This idea is not concrete enough; it fails to clarify two key components of hope," Dr. Snyder said.

    "Having hope means believing you have both the will and the way to accomplish your goals, whatever they may be."

    Despite the wisdom in the old saying "where there's a will there's a way," Dr. Snyder has found that the two are not necessarily connected. In a study of people from 18 to 70 years old, Dr. Snyder discovered: only about 40% of people are hopeful in the technical sense of believing they typically have the energy and means to accomplish their goals; about 20% of the people believed in their ability to find the means to attain their goals, but said they had little will to do so; another 20% have the opposite pattern, saying they had the energy to motivate themselves but little confidence that they would find the means; the rest had little hope at all, reporting that they typically had neither the will nor the way.

    "It's not enough just to have the wish for something," said Dr. Snyder. "You need the means, too. On the other hand, all the skills to solve a problem won't help without the willpower to do it."

Coding(编码) apps and programming apps for kids are becoming increasingly popular. Here are some of the best apps for teaching kids to code.

Scratch

Scratch is by far the most popular coding app for kids, and it is now used in many schools all over the world. It is available for free on the web as well as for Android and iOS, which is why it is so popular. Created in 2003 by MIT students and staff, its coding language is designed for children aged 7 to 16.

The language employs visual blocks or bricks that can be dragged and dropped on a workspace to construct logical chains. As a result, the child will have a better understanding of the fundamental principles of coding.

Daisy the Dinosaur

Daisy the Dinosaur is a free iPad and iPhone programming app. What distinguishes it from the rest is that it is designed specifically for children aged 4 to 7. The app was developed by the same team that created the Hopscotch coding app for kids. If you've ever used that app, Daisy the Dinosaur has a similar user-friendly interface with limited features that is best for beginners.

Cargo-Bot

Cargo-Bot is a free coding app that is available for both Android and iOS devices. It is appropriate for children aged 10 and up. This app specialises in puzzle challenges involving a robotic arm that must be programmed to perform various tasks, most notably moving coloured boxes to create a specific design or pattern.

Kodable

Another relatively well-known coding app for kids is Kodable.' It is free for: both the iPhone and iPad, but there is no option for Android or the web. Kodable is appropriate for both younger children and older teenagers(from 8 years old and up). It is also remarkable for guiding users from a basic to a complex level of coding.

The approach is very game-like, with users able to select a character to guide them through the levels.
