Several companies are racing to produce electronic paper and ink, complete with colors and moving imagines(图像). One idea would be to create a newspaper like The Daily Project in the Harry Potter books. Its pages would hold video clips of baseball games instead of just black-and-white photos.

   Electronic paper is not a new idea. A company in Massachusetts called E ink, for example, has been working for years on such a technology. Little electricity determines(决定)whether each microsphere(灌球)looks black or white at any given time. Together, microspheres make up words and imagines. The techniques seems promising for creating still imagines that can be changed when needed, but the process(进程)is too slow for good videos.

Scientists in the Netherlands now report a new type of e-paper technology. By using layers(层) of oil, the requirements. They can also make images which change fast enough to meet standard video requirements. They can also make brilliant colors. So far, however, each image is smaller than the fingernail.

For now, readingand watching TV will have to return two separate activities. Keep your eyes open, though, in the future, TV watching and reading might be part of the same work.

    E-waste is fast becoming a serious problem around the world. This report will examine this problem and provide some possible ways to solve it.

We live in a society that is producing and using electronics(电子产品) all the time. It is often cheaper to buy new products than to repair old ones. Also, through clever advertising, companies always encourage people to change their old TVs, mobile phones and computers for the latest models. E-waste is created when we throw away old ones. In the EU alone, about 8,700,000 tons of e-waste is produced each year. Sadly, just over 1,000,000 tons is recycled.

    Burying(填埋) e-waste or burning it cause serious problems for the environment. Electronics have dangerous things in them. These things can then get into the ground or pollute the air when they are burnt.

    In recent years,   ▲  . However, their plans are not always managed properly. Sometimes electronics are just sent to poor countries such as Ghana. Here they are often burnt in public areas, which is very bad for people's health. Setting up recycling centers is a good way to solve this problem. E-cycling centers could recycle the parts that can be reused and deal with the rest properly.

    Another way is to make producers responsible(负责任) for their used products. This means that producers must take back old products which are no longer wanted. They should then make sure they are properly recycled or reused.

    As for us, we should try to cut down on e-waste. Change electronics only when we have to. And don't buy a product just to have the latest model.

    E-waste is a serious problem in the modern world. Both producers and users must take actions and try to keep it to the smallest amount.

    The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the Earth is covered with water while we say we are short of（短缺）water. Why? Because about 97% of water on the Earth is sea water which we can't drink or use for watering plants directly(直接地）. Man can only drink and use the 3%-the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted(污染）.

    Now more water is needed. The problem is Can we avoid（避免）a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been researching in the field. Today, in most large cities water is used only once and then runs to the seas or rivers. But it can be used again. Even if(即使）every large city reused its water, there would not be enough. What can people turn to next?

    The seas seem to have the best answer. There is a lot of water in the seas. All that needs to be done is get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.

    When you carry your heavy schoolbag on the way to school or home, do you know the fact that the heavy schoolbag influences your interest in learning knowledge? Don't worry. You may be able to say goodbye to your heavy schoolbag in the near future.

    Instead of burying(埋葬) your face in an ocean of textbooks, newspapers, magazines and novels, you will soon find that an E-book reader can take the place of them all.

    An E-book reader is a new kind of mini machine designed to hold thousands of text files and display them on the screen as real text printed(印刷) on a paper page.

    In the same way in which the iPod(a kind of MP3) has changed the way people enjoy music, E-book readers could change the way that books are read. Some scientists have predicted that E-books will be used widely in our daily life, especially in schools.

    The size of an E-book reader is the same as that of real books. Its screen is different from that of a computer. It is as thin as a piece of paper. The words on an E-book reader's screen look exactly the same as those on real pages. However, you can do more with an E-book reader than you can with a real book. The reader can change the size of the words and connect to the Internet to download new books.

    How to build good relationships with people from other cultures? Actually, it is important to learn some communication skill. {#blank#}1{#/blank#}.

    Learn about the culture in advance. A little knowledge can go a long way. So if you have time before going abroad or meeting with someone from another culture, try to take time to learn the basic "do's and don'ts" of that culture. {#blank#}2{#/blank#} It's very convenient.

    Be respectful and tolerant. {#blank#}3{#/blank#} Signs of these may appear when you communicate with people from other cultures. However, it is not the time to judge people based on these differences during basic communication. Instead, respect them for what they are, and tolerate them.

    Speak clearly and slowly. But do not shout at others even if they don't understand you. {#blank#}4{#/blank#} Instead, it can be seen as a rude behavior. What's more, even if there are difficulties in communicating with people from other cultures, do not treat other people as though they are stupid.

    {#blank#}5{#/blank#} In some cultures, looking another person in the eye when you speak is seen as a sign of honesty and interest. However, in other cultures, it may be disrespectful.
