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

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

      Though the PaperPhone 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 PaperPhone.

The scientists from Queen's University in Kingston, Canada said the PaperPhone 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 PaperPhone on May 10th this year.

    Can plants eat people? Maybe not, but there are many plants that eat meat. Some of them are big and they can eat small animals. One famous meat-eating plant is the Venus flytrap(捕蝇草).

    The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. The fly (苍蝇) cannot get out. In about half an hour, the leaf presses (压) the fly until it is dead. Then, the plant covers(覆盖) the fly. Slowly, the plant eats the fly.

    Why do plants do it? Most plants get what they need from the sun, the air, and the ground (地面). In some places, the ground is very poor. It doesn't have all these important things, especially nitrogen(氮.). Animal meat has a lot of nitrogen, so many plants eat meat to get what they need.

    Let's hope that some of the bigger plants don't get the same idea!

    There are all kinds of animals on our planet. Some are sweet, but some are not; some are small, and some are tall. Here are four pictures of some of the funniest, friendliest faces. But remember, although they look nice, it doesn't mean they are always friendly.

    Not all dogs are so cute, but most of them are pretty friendly. When you come near an unfamiliar(不熟悉的) dog, remember to hold out your hand, so he can smell you and see that you mean no harm.

    Cows love to eat grass, and they eat quite a lot! You needn't be afraid of this quiet farm animal. But don't run at a cow in a field or touch one, unless you are told by an adult it's okay.

    Horses are big, beautiful animals, but they can be easily angry. A horse might jump up if she hears a loud noise, or kick her legs if you come near too suddenly. All horses, like humans, are different.

    Chimpanzees(黑猩猩) make funny faces and put on a real show at the zoo, but believe it or not, they can be very dangerous. And they are strong too--much stronger than humans--so you should never make a chimp mad!

    The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.

    Wrong idea No. 1: An invention has to be something completely new.

    Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright brothers, for example, got the idea for building a "flying machine" from watching birds.

    Wrong idea No. 2: Inventors are born, not made.

    There are a lot of factors(因素) that make invention possible. Take Mazart, for example. He was born with a talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"!

    Very successful creators don't give up when they get something wrong. As one inventor said, "A failure is the right answer to the wrong question."

    Wrong idea No. 3: Inventors are always old people.

    Don't believe that you can't invent something when you are young. Here are two examples of young inventors: Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.

    As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline(蹦床).

The Terracotta Warriors, one of the eight wonders of the world, have enjoyed international fame. Located in Xi'an in northwest China's Shaanxi Province, they are warriors of the first-ever emperor in1China or Qin Shi Huang in Chinese, Ying Zheng.

Even though I knew they are life-sized sculptures (雕塑), I was still2 when I saw them. I was lucky enough to3 the pit (深坑) and take a close look at them for the first time.

They were made around 2, 200 years ago. When I first got down into the pit, the sculptures scared me4some of them lacked body parts.

I was told that the Terracotta Warriors are not easy to preserve (保存;保护) for over thousands of years. But to my surprise, they were actually5 in color when they were first discovered. However, the color fell off6after being exposed in the air.

The difficulty of preservation is one of the reasons why they have stopped7out other pits. Although the Terracotta Warriors are breathtaking, they are only part of the Mausoleum (陵墓) of the First Qin Emperor.

Shen Wenxi, an expert and museum librarian of the Chinese Academy of Social Sciences, told me there's an even grander area8 man-made mountains, rivers and seas inside the emperor' s underground palace.

However, there is no plan to dig them until there are perfect9of protecting and preserving them. Experts are still busy restoring the relics (修复文物) that were10in the 1970s.
