    Astronauts (宇航员) face many problems when living in space stations. One of them is food. People on Earth put together all the meals first and then send these meals to space stations by space shuttle. Because the food has to last a long time (sometimes up to three months), people have to store a lot of it in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.

    Without the help of gravity sitting down to eat can be difficult. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful so that food does not float away.

    Hundreds of years ago, life was harder than it is today. People didn't have modern machines. There was no modern medicine, either.

    Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.

    Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt (被状物) over a city. This kind of quilt is called smog.

    Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.

    We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground. We can go to work by bus with our friends in the same car. If there are fewer people driving, there will be less pollution.

    Rules are not enough. Every person must help to fight pollution.

The kites in Weifang never disappoint. Every year the Weifang International Kite Festival amazes visitors with creative kites, as "paper birds" of varied designs keep appearing in the sky.

Kites in China can originate from the Warring States Period when Mozi made the first "wooden kite". Kites didn't actually become popular until the Ming Dynasty. By the middle of the Qing Dynasty, artists who were good at kite making began to appear in Weifang. In 1984, the first Weifang International Kite Festival was held.

Kites were used in China during the wars at the very beginning. For example, they can be used to record wind readings, similar to ship flags at sea. Over time, kites became connected with relaxing activities, and were often flown during festivals and holidays.

Today, kite-flying is a popular activity in China, and the Weifang International Kite Festival is one of the largest kite festivals in the world. In 2024, 622 kite artists from 59 countries and areas took part in the event. Zhang Xiaodong,74, has attended all the festivals. In the early days, he only brought traditional kites to take part in the competitions, but this time, he used sound and light to make the story of Chang'e flying to the moon come "alive".

The festival is a great platform to share kite-making skills. It also brings the people of China and other countries closer. As one citizen put it, "No matter how far away kite lovers go, there is always a 'thread' in their heart that can pull them together."

When a computer runs a group of programs, it can get very hot. Cooling the computer can cost a lot, so some scientists want to know one thing: What would happen if they use the heat from the computer?

Large Internet companies such as Google and Microsoft have thousands of computers. As people use these computers to look through information, they produce lots of heat so they need huge cooling systems. 

These systems send the heat into the air. A Company in Holland(荷兰) thought paying to make the computers work and then paying again to cool them were a waste of energy So the company developed a special machine—the e-Radiator. Boaz Leupe, head of the company, says that the e-Radiator works as a heating system and saves money. He says that the energy is used twice--once to heat the home and once to cool the computer. He also says that users don't have to pay to cool their computers. Five homeowners in Holland are testing the heating system in their homes. "We pay for using the computer, so, in that way, homeowners get heat for free, " Boaz says. Jan Visser is one of the homeowners. If you use the computer more, the e-Radiator produces more heat, he says. "It cannot provide enough heat if you don't use your computer often. " But he is ready to try it. It's a great help for his family. 

The company says e-Radiators produce heat of up to 55℃. It says the system could save its users about $440 a year. That's really wonderful, right?

 Friends bring us happiness and hope in our lives. Making friends is a skill and the first thing is to know how to get along with others. If you have trouble making friends, maybe I can tell you how to do it.

 Find your own advantages. {#blank#}1{#/blank#} You have our own skills and talents that others don't have. Believe that you are a good person and have something nice to share with others.

 Respect(尊重) others. Everyone has his or her own idea. Learn how to listen to others' ideas without trying to make them accept yours. We need to respect each other, because it increases confidence. {#blank#}2{#/blank#}

 Be kind. If you are kind to others, they will usually be kind to you. {#blank#}3{#/blank#} For example, saying hello to someone new. Most importantly, give your smile to everyone you meet on the way.

{#blank#}4{#/blank#} Learn to accept what you can't change, and work hard to change what you can. Nobody likes hearing your complaint all the time. If you complain too much, others will leave you.

 Never give up. Even if you face some close minded(保守的) people. If you try many times, they may accept you as their friend. And you can try to find someone who will understand you. Believe there are many people who like you.

Sailing a boat is great exercise, which can be enjoyed with family or friends. Many people all over the world sail each year. With some lessons and practice, you could be one of them. {#blank#}1{#/blank#}

● Understand the basics (基础知识)

When you're starting out in sailing, learn the basics first. {#blank#}2{#/blank#} It works like any sailboat-with sails to catch the wind and push the boat forward. The sailor, the person working the boat, has to be able to move the sails, as well as use a rudder (舵) in order to direct the boat where they want it to go.

● Find sailing near you.

The most important lesson you can learn in sailing is how to do it safely, with the help of experienced sailing coaches. {#blank#}3{#/blank#} Then ask your parents to call them to find out what lessons or camps they have for kids in your age group.

● Prepare for your lesson.

As a beginner, your lesson will start on land. You'll learn skills, like how to raise the sails by pulling on the lines. {#blank#}4{#/blank#} It includes the boat and a life vest (救生衣). Ask what type of shoes you should wear, and dress in clothes that will dry easily.

● {#blank#}5{#/blank#}

Remember to always wear your life vest on or near water, even when you're on the dock (码头). Don't go near a boat or take one out unless your parents agree, and never sail or swim alone.
