The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as "The Triangle of Death”for its strange seawater and sudden storms. What's the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.
　　At 2:00 p.m. on December. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was "completely lost". Then there was silence. Another plane was sent to look for them and also disappeared.
　　One of the largest ship that had disappeared in the triangle was an American coal ship, 500 meters long. The weather was good, and there were no messages for help before it was "gone". No broken ships or dead bodies have been found so far.
　　No one is able to tell how all these accidents have happened. A group of Japanese scientists were there to see what it was really like in 1995, but nothing has been heard of them ever since.

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.

    We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.

    Global positioning system(GPS)(全球定位系统)

    It's a system that uses radio signals from satellites to show exact(精确的) information. It tells you where the user is on the earth in all weather conditions. It's made up of three parts: satellites, control equipments(设备) on land and receivers.

    Space Technology

Russian and American scientists have worked together for the international Space Station(ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It's even hoped that one day spare technology will take humans to their new houses in space.

    Underwater Robot

Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.

The world is changing so quickly that it's hard for us to catch up with all the new inventions because they seem to come out every month. It's important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.

    In nature, you may see many insects(昆虫) and animals of different colors. Have you ever wondered why?

    Locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors, of locusts change with the colors of crops(庄稼). When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.

    Brown bears, tigers and other animals move quietly through forests. They can't be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark colored and they live under the soil(土壤)in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.

    Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

    You've got plenty of emails from your mom, and maybe even a few from dear old grandma. But have you ever received a message from a river?

    Now, Ireland's River Lee is sending out much information, thanks to wireless(无线的) technology. In a program called the DEPLOY project, scientists have put some sensors(传感器) in rivers that can find pollution levels.

    Instead of asking scientists to collect water samples several times a day, the government can now examine pollution levels in the water, and find out if there is anything polluted entering the river. This makes it much easier for scientists to protect the environment, since problems can be discovered before a serious pollution accident really happens.

    People in the area can also receive free reports from the river, so that they can find out whether the water is safe for swimming or boating on a certain day. And people can also know if the water is clear enough for them to drink and use.

    The DEPLOY project has not only started in Ireland, also the same programs have started in thousands of places around the U.S. Now you live in a world in which you could receive information with your mobile phone about environment. The technology should help to make us know more about the pollution that surrounds us—which just might get us all a little more involved with trying to clean up our world.

    A computer program that could help catch and ever translates from aliens in outer space has been started by a British scientist.

    If aliens are discovered one day, scientists fear their language may make it possible to understand them. But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structure(结构)of their language. He thinks that's the first step in understanding what they are saying.

    Dr. Elliott's program would compare an alien language to a database (数据库)of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure. Language has to be structured in a certain way, or it will be harder to use, he told New Scientist magazine.

    Research had shown that it is possible to know if a signal(信号)carries a language rather than a picture or music. Dr. Elliott has gone a step further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr. Elliott has set up a library of the sentence structures of 60 human languages.

    If a message is received from outer space, it could be compared against this database. Scientist would then be able to see if ti's similar to any human language, or a mix of the language.

    However, Dr. Elliott also said that in order to translate what the aliens are actually saying, it may still be necessary to have a code book.

Using iPads to Make Learning Fun

    Paper, pencil, whiteboard, textbook are the tools you need if you want to go to school. But recently, you can add another one to the list: an iPad.

    Because the popular Apple tablet is not only useful for searching the Internet and watching videos, but it is also being used to make learning fun.

    Scientists now know that we learn better when we are enjoying ourselves, so recently software developers have made iPad applications(应用程序) that look like video games, but have strong educational content. One of the best examples of this new form of teaching application is Futaba, game in which up to four children try to recognize a spinning旋转的）object, and then identify what it is. The game can be used to teach English, math, foreign languages, or just about anything, and students love it. Teachers can even make their own questions. The important thing is that children enjoy the game, and don't even realize how much they are learning!

    So the next time you have to choose between making your child study or letting them play game, just remember——they could do both at the same time!
