Exercise is a way of keeping the body healthy through being active. Another name for exercise is physical fitness. Most people exercise in their spare time. Sports are some of the most popular ways to get exercise.

    The two main kinds of exercise are aerobic exercise(有氧运动)and anaerobic exercise (无氧运动).Sports such as football and basketball are great forms of exercise. {#blank#}1{#/blank#}

    Aerobic exercise is energetic movement that lasts for a certain period of time.{#blank#}2{#/blank#}The lungs and the heart work harder to bring in extra oxygen. Swimming, cycling, running and rapid walking are good examples of aerobic exercise.

    Anaerobic exercise is a powerful burst of movement followed by a period of rest. During anaerobic exercise the muscles need more energy than the body can make with its supply of oxygen. After the exercise a person feels out of breath because the muscles have worked without oxygen.{#blank#}3{#/blank#}

    What Is Emotional Eating?

    Emotional eating is when people use food as a way to deal with feelings instead of satisfying hunger{#blank#}1{#/blank#}Have you ever finished a whole bag of chips out of boredom or downed cookie after cookie while preparing for a big test? But when done a lot — especially without realizing it — emotional eating can affect weight, health, and overall well-being.

    Not many of us make the connection between eating and our feelings.

    {#blank#}2{#/blank#}One of the biggest myths about emotional eating is that it's caused by negative feelings. Yes, people often turn to food when they're stressed out, lonely, sad, anxious, or bored. But emotional eating can be linked to positive feelings too, like the romance of sharing dessert on Valentine's Day or the celebration of a holiday feast. Sometimes emotional eating is tied to major life events, like a death or a divorce{#blank#}3{#/blank#}

    Emotional eating patterns can be learned: A child who is given candy after a big achievement may grow up using candy as a reward for a job well done.{#blank#}4{#/blank#}It's not easy to “unlearn” patterns of emotional eating. But it is possible. And it starts with an awareness of what's going on.

    We're all emotional eaters to a degree. But for some people emotional eating can be a real problem, causing serious weight gain or other problems. The trouble with emotional eating is that once the pleasure of eating is gone, the feelings that cause it remain{#blank#}5{#/blank#}That's why it helps to know the difference between physical hunger and emotional hunger.

Next time you reach for a snack, wait and think about which type of hunger is driving it.

A. Believe it or not, we've all been there.

B. If a crying boy gets some cookies, he may link cookies with comfort.

C. One study found that people who eat food like pizza become happy afterwards.

D. And you often may feel worse about eating the amount or type of food you like.

E. Understanding what drives emotional eating can help people take steps to change it.

F. Boys seem to prefer hot, homemade comfort meals, while girls go for chocolate and ice cream.

G. More often, though, it's the countless little daily stresses that cause someone to seek comfort in food.

    Any exercise is good exercise, but when it comes to losing weight, it's hard to beat running. After all, running is one of the most efficient ways to burn calories and get fit without having to restrict your diet. {#blank#}1{#/blank#} If you're not a runner yet but interested in losing weight, here are four reasons running can be the best exercise for weight loss.

    {#blank#}2{#/blank#}When comparing running with walking the same distance, studies find that running will lead to greater weight loss, most likely because your resting energy expenditure stays elevated(高的) after you run. In a long-term comparison study of runners and walkers, calories burned through running led to 90% more weight loss than calories burned through walking.

    Running is time-efficient. Even if the myth that running a mile and walking a mile burn the same number of calories were true, running is a considerably faster way to burn those calories.{#blank#}3{#/blank#} 

    Running is convenient. Though many of us have accumulated a vast arsenal（武器，装备） of GPS gadgets and tech tees over the years, little is actually required to go running. You can do it alone. You can do it almost anywhere. {#blank#}4{#/blank#} For this reason alone, running is the best workout for weight loss because it's cheap and accessible, and there are fewer barriers to maintaining a routine, even while traveling.

    Two words: runner's high. {#blank#}5{#/blank#} Fortunately, studies support what many runners have experienced on an anecdotal level—running can actually get you high. Scientists have found links between moderate to intense exercise and morphine-like brain chemicals, which explains the occasional flood of thrill that rushes over you during a hard run. That happy sensation you had after your last race makes you want to go for another run, right?

A. Cultivate the good habit of running.

B. Running works even when you're at rest.

C. You will never stick to a habit if you don't like it.

D. The first rule of exercising for weight loss is that if you don't enjoy it, you won't stick with it.

E. You don't need any equipment beyond a pair of running shoes.

F. If you're already a runner, keep on.

G. Most people can run two or three times as far as they can walk in a given amount of time.

    Futurologists (未来学家) predict that life will probably be very different in 2050.

    TV channels will have disappeared. {#blank#}1{#/blank#} Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers and books will come to us by computer.

    {#blank#}2{#/blank#} Cars will have computers to control the speed and there won't be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.

    {#blank#}3{#/blank#} Many factories already use robots. Big companies prefer robots—they don't ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

    {#blank#}4{#/blank#} Today, there are devices (设备) that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again with the help of new technology.

    Scientists will have discovered how to control genes. {#blank#}5{#/blank#} By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
