Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. {#blank#}1{#/blank#}

    Paper was first created about 2, 000 years ago, and has been made from silk, cotton, bamboo, and, since the 19th century, from wood. {#blank#}2{#/blank#}But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren't many books, few people learned to read.

    {#blank#}3{#/blank#}When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. {#blank#}4{#/blank#}

    Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD-ROMs or machines such as MP3 players.

    Computers are already used in classrooms, and newspapers and magazines can already be read online. {#blank#}5{#/blank#}No, I don't think the poster about Yao Ming on my bedroom wall will ever be replaced by a two-metre-high computer!

    Today more and more children wear glasses before going to middle school. They keep their eyes watching TV or playing computer games for a long time. Eyes are the windows of our hearts (心). We use our eyes to see everything around us, so we should know how to protect our eyes.

    Love our eyes. When we open (睁开) our eyes every day, we can see the lovely friends and parents, beautiful flowers and green trees. If our eyes don't work, how can we see the world. In our eyes, everything and everywhere is dark. It's like a house with no light (光). How important our eyes are!

    Relax our eyes. First, stop to relax 30 minutes when using the computer for an hour or two. Next, remember to do eye exercises every day. Then, looking at green trees also helps a lot. In these ways, our eyes will feel relaxed.

    Have good habits. When writing homework and reading, it is important to keep a distance (距离) of 30 cm between your eyes and books. Remember to use our eyes in a right way. Don't read in bed or on a moving bus. Eat something healthy for eyes, such as carrots, fish and eggs.

    Follow my advice (建议) and get good habits. It's time to say goodbye to thick (厚的) glasses.

Everyone wants to be successful, but failure (失败) is a common thing for us to meet with. 1, sometimes we fail the exams; sometimes in the sports meeting, others 2 but we fail. So almost 3 meets with the failure in his life.

However, different people have different 4 to deal with(处理)the failure. Some people lose hope when they fail. They seem to think that it is the 5 of the world. But others don't take failure 6. They seem to think that failure is the first step(步骤)to success. They will 7 and try their best to get the final success.

Now let's imagine( 猜想)the ends of the two ways. If we are afraid of the failure and always feel sad, and don't try our best to change ourselves, we may meet with more and more failures. But as 8 as we are hopeful and brave to face the failure, and never give up, we will become 9 and our dreams will come true some day.

So, please remember: Life doesn't give us the pleasure we want. But if we never give up and 10do little by little, it will make a big difference.

    Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk (垃圾) has become a problem in outer space too.

    According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

    Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.

    To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

    To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

    Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

    "The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.

    "The time to act is now. The longer we leave the problem, the bigger it will become," he says.

In San Francisco, there is a special group of volunteers. They call themselves Friends of the Urban (城市的) Forest (FUF). These volunteers want to {#blank#}1{#/blank#}. Every year, the FUF plants nearly 1,000 trees.

The FUF welcomes new volunteers all year round and in all parts of its work. On Weekend Planting Days, FUF volunteers work with common citizens (市民) to plant trees. The planting usually runs from 9 a.m. to 1 p.m. After the work is done, everyone {#blank#}2{#/blank#} over a community lunch.

On Thursday Planting Days, the FUF plants "replacement (替换) trees". As their name suggests, these trees replace trees {#blank#}3{#/blank#}. Planting Leaders are very experienced volunteers. They are able to help other volunteers at planting events. Planting Leaders usually wear a special FUF T-shirt. Some new volunteers know little about "replacement trees". They can easily find Planting Leaders and {#blank#}4{#/blank#}.
