Each summer, you hear news that some sports players are sent to hospitals because it is too hot. Our bodies can't be outside in the sun for a long time. So in hot summers, be careful about playing sports outside.

    Firstly, to play sports safely in hot weather, you must drink water. Sports drinks are great for athletes, but they have so much sugar that they'll dehydrate（使脱水）you more. However, drinking afew bottles of sports drinks will be good for you.

    Secondly, be sure to take enough breaks to let your body rest. If your coach doesn't let you do so in the heat, don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks.

    Thirdly, when you have a break, don't sit in the sun. With the sun beating down on you, you'll only heat up and sweat（冒汗）more. Take a seat under a tree, or even better, go indoors for a little while.

    Cooling yourself down can help you stay active longer.

    Fourthly, remember that the earlier in the day you start your exercise, the cooler it will be. If you can start practice before the sun comes up, you have a few good hours to practice in the cool hours of the morning. Also, the earlier you practice, the earlier you can finish the exercise. If you need more practice time, come back to the field later in the evening when the sun is setting.

Last but not least, you should watch your food. Eat food which is high in water, starch（淀粉）and carbohydrate(糖类), but be sure to get a good balance in your diet.

    As long as you pay attention to the above, playing sports safely in the heat isn't a difficult thing.

    Can you imagine astronauts' everyday life in space? {#blank#}1{#/blank#}They do the same things as us, but they do them differently.

    {#blank#}2{#/blank#} Gravity(重力) holds the food down and keeps the water in the glass. But there is almost no gravity in space, so food can float(漂浮)away, and astronauts must eat and drink carefully.

    Sleeping is very different in space. {#blank#}3{#/blank#} They tie the bag to a wall so that they won't float away, and astronauts must eat and drink carefully.

    Exercise is very important in space. On earth, your legs carry your body, but in space, astronauts float. {#blank#}4{#/blank#} This is very bad for their legs, so they must exercise for thirty minutes every day.

    After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families by radio.{#blank#}5{#/blank#}

A. So they do not use their legs often.

B It's very expensive to take food into space.

C. Sometimes they just enjoy floating in the air.

D. They also need to eat, sleep, exercise and relax.

E. On earth, we put food on a plate and water in a glass.

F. Astronauts have already visited the Moon and lived on space stations.

G. Some astronauts like to float in the air, but most like to be in a sleeping bag.

Dear Tom,

    Most of the time, I just stay at home for my vacation. That's too boring. But I had a special and exciting vacation last summer. My classmates and I made a trip to Mount Tai by bus.

    When we arrived there, it was dark(天黑). At 7 pm, we began to climb the mountain. It took us the whole night to get to the top of the mountain. On the morning of the next day, we enjoyed the beauty of the sunrise on the top. That's wonderful. In the daytime, we visited a temple (寺庙). In the evening, we had a big dinner in a local restaurant together. The food there was delicious but a little expensive.

    I hope you can come to China next year. Then we can visit more interesting places together.

Yours,

Mike

    Some of us students are still afraid to sleep alone. But my robot can help. It can read stories and sing songs to you when you go to bed. You can have a nice sleep every night with my robot.

    I'd like to make a robot cleaner. Our parentsare very busy with work, but they still have todo some housework when they get back home. A robot cleaner can help with the housework a lot. Then Mom and Dad can play or talk with us. Isn't that great? Zhang Liaoxing, 13

    All robots should be able to protect their owners. My robot is as powerful as the famous hero Robocop. But it is much smaller. It looks like a student. We go to school together every day. But when there is an emergency (紧急情况), it will protect us students and fight against the bad guys(家伙) at once.

    I often feel lonely, so my robot will be very friendly and kind. It can know your feelings and react (反应) like your friends. I will also let the robot read, so it knows a lot and can teach us about right and wrong, just like our parents. In a word, with my robot, you won't feel lonely any more.

The Art of Paper

    Chen Zijiang is a paper cutting expert whom I interviewed for my article on Chinese Art. Paper-cutting is something that he learned to do from an early age.

    "It is a Chinese folk art with a long history," Mr. Chen told me, "Paper cuts of animals have been found in tombs. {#blank#}1{#/blank#}" He added that by the Southern Song Dynasty, paper-cutting had become an important part of everyday life.

    {#blank#}2{#/blank#}They are paper cuts for decoration, for religious purposes (宗教目的) and for design patterns.

    Paper cuts for decoration are often seen, on windows and gates. {#blank#}3{#/blank#}They are also used on presents. A present for parents whose child has recently been born might show a paper cut of children, for example. Paper cuts which show the Chinese character for double happiness are often used to celebrate weddings.

    Paper cuts for religious purposes are often found in temples{#blank#}4{#/blank#}

    The third kind of paper cuts are these used to make patterns on clothing. They are also sometimes used to decorate jewelry (珠宝) boxes. {#blank#}5{#/blank#}.
