Is your schoolbag too heavy to carry? The e-schoolbag will help you. In fact, the e-schoolbag should perhaps be called an e-textbook. It is a small computer for students. Heavy schoolbags have been a serious problem for them for a long time. But the e-schoolbag will change everything.
It is much lighter than a usual schoolbag. Also, it is as small as a usual textbook, an exercise book and so on. They can be made into chips that are as small as a stamp. The students can read the text page by page on the “screen”, take notes, or even send e-mails to their teachers. All they have to do is to put the right chip into the e-schoolbag and press the button.
It is said that e-schoolbags have been put into use in some Chinese middle schools. In 2012, some students in Shanghai started to use e-schoolbags in the new term. Some say that e-textbooks can be easily broken. Some say it is not good to students’ eyes. But only time will tell us all.

The ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?” asked Jamie Taylor of the Wave Energy Group in Scotland. “There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity. The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland.
Most waves are created when winds blow across the ocean. “The winds start out by making little ripples (波纹) in the water, but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the coast, people can set up dams(大坝) to block the water and send it through a large wheel called a turbine(涡轮). The turbine can then power an electrical generator(发电机).
We will never run out of wave power. Besides, wave energy does not create the same pollution as oil and coal do.
Oceans cover three quarters of the earth’s surface. That would make wave power seem perfect for creating energy around the world. But there are some disadvantages that need us to pay more attention to.
Jamie Taylor said that wave power still cost too much money. He said that its influence on animals in the sea is still unknown. Besides, wave power would get in the way of fishing and boat traffic.
With more research, “Many of these problems might be solved,” Taylor said. “Finding more energy sources(资源) is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light button, an ocean wave could be providing the electricity!
小题1:We can learn from the passage that__________________.
| A．almost every country is making use of the wave power at present |
| B．it is necessary for us to develop wave power instead of oil and coal |
| C．wave power will be sure to make some bad influence on sea animals |
| D．scientists are making efforts to find new ways of fishing and boat traffic |

Even though global warming may have made the weather more mild, many animals are still hibernating（冬眠）. It’s too bad that humans can’t hibernate. In fact we almost did.
Apparently, at times in the past, farmers in France liked a semi-state of human hibernation. So writes Graham Robb, a British scholar who has studied the sleeping habits of the French farmers. As soon as the weather turned cold, people all over the France shut themselves away and practiced the forgotten art of doing nothing at all for months.
In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed since the invention of lighting.
When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ continuous sleep is a modern invention.
In the past, without the artificial light, humans went to sleep when it became dark and then woke themselves up around midnight. The late night period was known as “The Watch”. It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbors.
According to some sleep researchers, a short of insomnia（失眠）at midnight is not a disorder. It is normal. Humans can experience another state of consciousness（清醒状态）around their sleeping, which happens in the brief period before we fall asleep or wake ourselves in the morning. This period can be a creative time for some people.
Playing with your sleep rhythms（节奏）can be dangerous, as worry may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.
小题1:The late night was called “The Watch” because it was a time for people ______.
| A．to set time to catch animals |
| B．to remind others of the time |
| C．to guard against possible dangers |
| D．to wake up their family and neighbors |
| A．sleep in the way animals do |
| B．follow their natural sleep rhythms |
| C．keep to the eight-hour sleeping way |
| D．ask doctors for help if they can’t sleep |
| A．To throw new light on human sleep. |
| B．To encourage people to sleep less. |
| C．To give some suggestions on insomnia. |
| D．To find out people’s hibernating history. |
Early to bed and early to rise makes a man healthy, wealthy and wise.
This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.
Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours’ sleep every night. If you do not go to bed early, you can not have enough sleep. Then you can not think properly and you can not do your work properly. You will not be wise and you may not become wealthy!
Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us to sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.
Exercise helps the blood to move around inside the body. This is very important. Blood takes nutrition (营养) to all parts of our bodies. The brains in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!
Our bodies also need air to breathe. Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.
小题1:The old English saying“Early to bed and early to rise makes a man healthy, wealthy and wise.”mainly shows _______.
| A．what good habits are |
| B．what bad habits are |
| C．how to become healthy, rich and clever |
| D．it’s easy for people to get up and go to bed early |
| A．may not be strong |
| B．may not become wealthy |
| C．can not think and do their work properly |
| D．will not get up early |
| A．correctly | B．carefully | C．quickly | D．easily |
| A．fresh air | B．enough sleep | C．good habits | D．exercise |
| A．old people | B．middle-aged people |
