    Maybe you know floods, earthquakes, sandstorms and so on. But did you hear of typhoons(台风)?

    Typhoons are some of the worst storms, usually around the Pacific Ocean（太平洋） and the South China Sea. Most happen in July, August and September.

    How does a typhoon happen? When lots of sea water gets hot in the summer sun, it evaporates （蒸发）into the air. This makes the air hotter. When the air gets warm enough, it starts to move higher up into sky. Then cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles（圆圈）and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when the wind moves faster than 30 meters a second, a typhoon begins.

    A typhoon has two parts, one is called the “eye”. In the eye, the wind does not move so fast. The other part is the wall of clouds around the eye. Here are the strongest winds and hardest rains.

    Typhoons are very dangerous. In November this year, Typhoon Haiyan killed 5500 people in Philippines. More people are missing（消失）.

    What to do when a typhoon hits（袭击）?

⒈Stay inside. Close all the windows and stay away from them.

⒉Try to bring all of your things inside. Strong winds could even blow away your bikes!

⒊Listen to the radio or TV for important information.

⒋If you're told to go to a safer place, do it right now.

Kids' health: Four steps for fighting stress

    Everybody gets stressed from time to time.{#blank#}1{#/blank#}Some ways of dealing with stress like screaming or hitting someone--don't solve (解决)much. But other ways like talking to someone you trust, can lead you to solve your problem or at least feel better.

    Try taking these four steps the next time you are stressed:

    ⑴Get support.   When you need help, reach out to the people who care about you. Talk to a trusted adult, such as a parent or other relatives.{#blank#}2{#/blank#}They might have had similar problems, such as dealing with a test, or the death of a beloved pet.

    ⑵Don't take it out on yourself.   Sometimes when kids are stressed and upset they take it out on themselves. Oh, dear, that's not a good idea. Remember that there are always people to help you. Don't take it out on yourself.{#blank#}3{#/blank#}

    ⑶Try to solve the problem.   After you're calm and you have support from adults and friends, it's time to get down to business.{#blank#}4{#/blank#}Even if you can't solve it all, you can solve a piece of it.

    ⑷Be positive.   Most stress is temporary (暂时的). Remember stress does go away, especially when you figure out the problem and start working on solving it. These steps aren't magic, but they do work~ And if you can stay positive as you make your way through a tough time, you'll help yourself feel better even faster.{#blank#}5{#/blank#}.

You're standing in the kitchen and a voice says, "put a little more salt to that soup"

Yes, it's always nice to have1 help you when you're2 .

3 this voice is not from a person. Then4 does it come from ?Is it from a ghost ? No, this isn't a ghost kitchen —it's the kitchen of the future. 

Scientists are5 to make everything in the kitchen get better. They are making a system (系统）. It will help us cook a meal.

You don't need cook book s. You can hear how to cook food.

The first computer came out in 1946. It was very1 and it worked slowly. Today computers are much smaller and2 faster. What can computers do? A writer said, "People can't live3 computers today."

The4 came a little later than computers. It is about 25 years5 than computers. But now it is almost6 . We use it to read books, do some shopping, play computer games or make friends. Many students use the Internet quite often. They7 online and maybe they never know these people. They don't know their8 names, ages and work. They are so interested in making the "unreal friends" that they can't put their hearts into9 . Many of them become poorer (更糟糕) in subjects than before10 that.

Computers and the Internet let us learn more about the world, but we should remember that they can't do anything.
