The Dress That Turns into a Coca Cola Machine 

    This specially designed dress looks like a normal dress，but if you unfold it and cover yourself，you may look like a Coca Cola vending machine（自动售货机）. Because there are many vending machines like that on the street，it must be easy for you to hide．If you feel that someone is following you or there is some danger，you can disappear within five seconds．But don't use it to scare your classmates．That'll be rude.
                                  

    The M-Dress is a nice black dress．It is also a mobile phone．It accepts a standard SIM card and allows the wearer to receive calls without carrying an actual(真实的) phone in their pocket or purse．You just need to bring your hand to your ear when you want to answer a phone call．When you finish talking and release your hand，the call will close．It is fashionable and useful．But it will certainly be an embarrassing moment when your dress rings in public．
  Air Conditioned Jackets 

    You will love these air-cooled jackets in summer time when it is very hot outdoors．The jacket has fans that draw air in．The fan is powered by an inside battery．Now it is possible to spend nearly every second of your day with cool air．

    The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.

    Water pollution

    A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many river and lakes are now dead.

    Air pollution

    In big cities, factories, as well as cars, trucks and buses are the biggest cause of air pollution. Many people in cities now have bad health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is almost covered by thick brown clouds.

    Soil pollution

    In order to have a good harvest, most of the farmers use chemicals too much on their fields. That's bad for the soil. But this kind of pollution is difficult to stop.

    Hope for the future

    These problems are very serious for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Let's be greener people.

      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 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 space 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 look 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.

Pollution

    Hundreds of years ago, life was much 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 （污染）. Water pollution has made our rivers and lakes dirty. It kills our fish and polluted our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It's bad 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 over a city. This kind of quilt is called smog（烟雾）.

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

    We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or 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.

    Mobile phones are very popular with people. They are becoming smaller and more convenient.

    Now the scientists in Canada made a smart phone (智能手机)from electronic paper. The Paper Phone is flexible. People can control it by bending it or writing on it with a pen.

    Though the Paper Phone is only millimeters (毫米)thick, people can do many things with it. For example, people can use it to make phone calls, read books, watch movies and play music. So many people use it as a computer.

    The scientists think there will be no paper in the office. And people can store what they want in the Paper Phone.

    The scientists from Queen's University in Kingston, Canada said the Paper Phone would be in style in the future. It may be the end of paper and printers.

    To make people be interested in this kind of mobile phones, the scientists will make it more beautiful. People will see the Paper Phone on May 10 this year.

    We all know that many women like to wear dresses. They enjoy many kinds of colourful and popular dresses. But have you ever heard of a 4D dress?

    Jessica Rosenkrantz in the USA used 3D printing technology to make a very special and new dress. It will help with the problems of different styles of women's dresses.

    The dress maker called the special dress a"4D dress" ". It is like the fabric(织物). It can turn into different kinds of shapes.

    The company, in Massachusetts, the USA, also made a smartphone and an app(应用). They can help women to control their dresses. If women use the phone and the app, they can change the colour, the style and many other things of the dresses. Isn't it very interesting?

    When she talked about her work, Jessica said, "There will be many more changeable dresses for women in the future. I am interested in making them too, I can't wait to make different kinds of new dresses for women."
