A hundred years ago, most people thought that human beings would never fly. And the idea of flying seemed crazy and dangerous. But as a new world full of new inventions（发明物）came, everyone was trying to break the old thoughts. So many inventors, like Orville and Wilbur Wright, tried to make a flying thing.

    Most plane inventors at that time were impulsive. They would think of an idea, make a plane as quickly as they could, and then try to fly it as soon as possible. All of them had the same result they took their planes home and they had no idea why they didn't work.

    However, the Wright brothers were much smarter inventors. They tested their ideas in smaller or safer ones before making a real plane. For example, the Wright brothers made a wind tunnel(隧道)to compare(比较)wing shape ideas. They also flew lots of kites to test their ideas. They studied the way birds fly through the air and tried to learn something from it when making their models. Finally, the Wright brothers felt they were ready to test their planes, but they needed to find the right place. They knew the right place to test their planes after writing to the US Weather Bureau for help. At last on December 17th, 1903, Orville and Wilbur tested the plane and they made it.

    The plane flied for twelve seconds and it traveled just 120 feet, but Orville and Wilbur were very happy. Their plane really worked! By the end of the day, both brothers had great successful flights(飞行), with Wilbur having a record of 852 feet in 59 seconds.

    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. Andtheseare 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 Germany (德国), many children learn how to ride their bikes when they are very young. But if they want to ride bikes by themselves on the street, they have to pass a test (考试). The test is like our driving test.

First, the students must learn about how to ride bikes safely on the street. They'll have about 30 classes. Each student has a book and the book tells them how to keep safe on the street and how to keep others safe.

After the classes, the students will have two writing tests. Then, they will do some riding practice (练习) at school. Some policemen will come to give them more guides.

At last, the students will have a test on the street. Some policemen will grade the students. If they can pass the test, they can get a bike licence (执照). Then they are ready for the street!

We all know German people are very precise. We can see this from their riding test for the primary school students. The students not only learn useful riding skills (技能), but also learn the spirit (精神) of the country!

We recycle (回收利用) rubbish, so why not language? Recycling language means using vocabulary（词汇）that you have learnt before again and again. However, unlike rubbish that piles up (堆积) in our environment, if we do not recycle language, we simply forget it. So how do you recycle language?

There are basically（主要的）three ways to do it. The first is through reading. Go back to your favourite articles and read them once more. Just reread them and do not worry about each vocabulary item. If there are some that you are not sure about, make a guess and you will probably guess right. The second way to recycle is through writing. Look at some of your favourite articles and write either a short paragraph or a few sentences in your own words. After you have done this a few times, go back and read through what you have written, checking vocabulary functions. Don't worry if you have made mistakes. That's how you learn. The third way to recycle language is by having an imaginary chat with yourself about your favourite articles at home. You can pretend there is someone with you who speaks English and tell him what you are thinking about or how you feel.

Having a tea party is a kind of custom of drinking. It is a fun way to celebrate a special thing or offer time for friends to have a talk. The ideas you need to prepare a beautiful tea party are all right here. Read the ideas and use the ones that work for you.

It is important to make the tea party invitation. You should make a plan about who you'll invite to your party first. You should make the invitation card special, such as making it in the shape of a teacup or writing the lovely words on the card. Be sure to give the start time, end time, date and address (地址) of the tea party.

Make your home into a fun place. Cover the table with the prettiest clothes. Put cups and flowers in the middle.

Sometimes it's common to have some games or events at the party such as playing musical chairs, dancing to the music, making some art works and so on. It will be something special that helps them remember and share their events with others.

The drinks are the main role at your party. Lemonade, punch (混合饮料) or tea drinks are always top of the list. Well, don't forget to add some delicious cakes, sandwiches and fruit.

Everyone loves party gifts. Give them to your guests and say thank you for coming. It's always much nicer if you see them off your house after party.
