Trampolining

    What's more fun than standing still? Jumping up and down on a springy piece of fabric (织物)! This activity is known as trampolining and it's sweeping the nation.

    The idea of trampolining is ancient. Eskimos have been throwing each other in the air for thousands of years. Firemen began using a life net to catch people jumping from buildings in 1887. {#blank#}1{#/blank#}

    A gymnast named George Nissan and his coach Larry Griswold made the first modern trampoline in 1936. {#blank#}2{#/blank#} They named their equipment after the Spanish word trampolín, which means diving board. The men wanted to share their idea with the whole world. In 1942 they began making trampolines to sell to the public.

    Trampolines may be fun, but they can also be dangerous. {#blank#}3{#/blank#} Clubs and gyms use large safety nets or other equipment to make it safer. Most trampoline injuries happen at home. Since trampolines are more affordable than ever, injuries are even more common.

    These injuries happen for many reasons. People may bounce too high and land out of the trampoline or onto the springs. {#blank#}4{#/blank#} Perhaps the worst injuries happen when untrained people try to do flips (快速翻转). Landing on your neck or head can cause injuries or even kill you.

    {#blank#}5{#/blank#} There are many things that you can do to practice safe trampolining. Trampolines have been around for a while now. They have brought a lot of joy to many people. They can be a good source of exercise and activity. They can help people improve their balance and moves. But they can also be deadly. It is important to follow some professional guidance. Be sure that you are practicing safety while having a good time. Happy bouncing!

Guide for Teenagers

    The teenage years can be tough，and it's normal to feel sad every now and then. But if these feelings don't go away or become so intense that you can't handle them，you may be suffering from depression. {#blank#}1{#/blank#}

Try not to isolate yourself

    When you're depressed，you may not feel like seeing anybody or doing anything. Just getting out of bed in the morning can be difficult，but isolating yourself only makes depression even worse.{#blank#}2{#/blank#}．Spend time with friends，especially those who are active.

Keep your body healthy

    Making healthy lifestyle choices can do wonders for your moods. Ever heard of “Runners High”？Physical activity can be as effective as medications for depression，so get involved in sports，ride your bike，or take a dance class. Any activity helps！{#blank#}3{#/blank#}．As for food，make sure you're feeding your mind with plenty of fruits，vegetables，and whole grains.

Avoid alcohol and drugs

    You maybe try drinking or use drugs in an effort to escape from your feelings and get a “mood boost”，even if just for a short time. However，substance abuse can not only make depression worse，but can cause you to become more depressed.{#blank#}4{#/blank#}．You will need special treatment for your substance abuse problem.

    Life is difficult to everybody, so you need to organize your life well. Here are some suggestions which might give you some help to manage your life well.

    Write everything down and do not rely on your memory.{#blank#}1{#/blank#} If you want to remember things, put them in writing, or in a digital notebook. Keeping your to-do lists and other information written somewhere allows you to look back at them anytime, especially when you have hit your head and forgotten some of them.

    {#blank#}2{#/blank#}Try this experiment before buying one thing, throw out something old or something you do not use. Or, if you are a really pack rat(不想扔任何东西的人), just throw out one old thing a day until you can not find any more items to throw.

    Recycle and donate. Is your closet full of unopened bags and clothes that still have their tags(标签) on? Is your bookshelf full of unread books? Chances are that if you have not read, worn, or used whatever they are, they you are probably not going to use them at all.{#blank#}3{#/blank#}

    Create daily, weekly and monthly timetables for cleaning. Organize your cleaning timetable.{#blank#}4{#/blank#} Distribute tasks properly, so for example, dish washing could be done daily while vacuuming(吸尘) could be done weekly and cleaning the windows done monthly. Whichever of these tasks you decide to do, remember that you can not completely organize your life in one go(一口气).

    Scientists say eating less can slow the aging process of cells in the body. The researchers studied mice, not people.

    {#blank#}1{#/blank#}One group was able to eat as much as it wanted. The other animals in the other group are limited to eat. Their diet had 35 percent fewer calories than the first group of mice.

    The mice with the diet restrictions(限制) were more energetic and suffered fewer diseases. They were not just living longer, they seemed to stay younger for a longer period of time. When you restrict calories (in mice), there is a direct increase in lifespan - the average age of the animal{#blank#}2{#/blank#}

    But how? The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes (核糖体). Ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down.{#blank#}3{#/blank#}This, in turn, keeps cells and the entire body functioning well.

    Earlier studies have suggested a link between calorie restrictions and slowed aging{#blank#}4{#/blank#}Calorie restriction as a way to slow aging has not been tested in humans. But the main finding for people is the importance of taking care of our bodies{#blank#}5{#/blank#} And this may help us make better decisions about what we eat.

A. The less we eat, the healthier we are.

B. Researchers studied two groups of mice.

C. This finding is good news if you are a mouse.

D. This gives the cells more time to repair themselves.

E. The findings help to explain how exactly our bodies age.

F. However, this is first to show how the ribosomes can influence aging.

G. Calorie restriction caused real biochemical changes that slowed down the rate of aging.
