We all know the sun is important. It makes life on our planet possible. But how does the sun do that? It’s the sun’s energy.
Energy from the sun is called solar energy (太阳能). It comes in the form of light or heat. People have used solar energy for thousands of years. The sun’s energy can be used to heat water and even food. If you own a magnifying glass, your parents have probably warned you not to leave it in the sun. Solar energy can actually make the magnifying glass burn objects underneath it causing a fire. This type of energy from the sun is called solar thermal (热的) energy.
We can also turn the sun’s light into electricity. This is done with solar panels (板). Solar panels are made up of a material called silicon (硅). The silicon is heated and formed into very thin wafers (晶片). When the sunlight hits the solar panel, the electrons in the silicon move and flow through wires (电线). Using this technology, we can run a calculator and even power cars in an easy way.
But what happens on cloudy days? The electrons in the silicon will stop moving, which means the electricity can’t flow. But this doesn’t mean that solar energy can only be used on sunny days. People can use the batteries (电池) which are attached to (附着于) solar panels to store the electricity. So the stored electricity can be used to power cars at night or on cloudy days.
Did you know that solar energy is not as expensive as it used to be? In fact, in the last few years.solar panels have become much more affordable for people to use. Since the sun gives off more energy in one second than people have used, imagine what we could do if we used the sun’s energy to power our planet.

【推荐1】Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.
According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

Scientists have worked out when our Sun will die. It won’t be any time soon. It will be in 10 billion years. The scientists are from the University of Manchester in the UK. They predict that in about 5 billion years from now, the Sun will turn into a “red giant”. This is the scientific name given to a star at the end of its life. When our Sun becomes a red giant, its centre will shrink (收缩) . Its outer layers will expand (膨胀) as far as Mars. This means Earth will be burnt and disappear. After our Sun turns into a red giant, it will become a bubble of gas and space dust. The scientists say no humans will be on Earth when the Sun dies out.
The Sun is still quite young in space years. It is just 4.6 billion years old. This means it is only around one third into its lifespan (寿命) . Professor Albert Zijlstra, a scientist from the University of Manchester, explained what happens at the end of a star’s life. He said, “By this point in the star’s life, it is running out of fuel. Then it turns off and dies.” Professor Zijlstra was happy that modern science can count the age of stars and what will happen to them. “We even have found out what the Sun will do when it dies.” He said.

[1] World Sleep Day, organized by the World Sleep Day Committee of the World Association of Sleep Medicine since 2008, is held on March 21 every year. We are often told that it’s important to get enough sleep, but do we know why? The truth is, even scientists can’t agree on why we need to sleep. (74)①________, they are in agreement that sleep quality plays a key role in people’s health. It’s clear that the less we sleep, the worse we perform in everyday life.
[2] Have you ever felt tired in the middle of the day, especially after lunch? Actually, this is quite normal. Researchers have found that it may be healthier to sleep twice a day—a long sleep at night, and a nap in the afternoon. (75) Even a ten-minute nap at lunchtime can allow us to work better in the afternoon. And if we really can’t find a chance to nap, we should get a longer sleep at night so we don’t feel tired after lunch.
[3]Not getting enough sleep has serious (74)②________ on our brain’s ability to work. If you go without sleep, you might have problems with your memory or with your concentration. In order to concentrate at school or perform well in tests, we really need to get a good night’s sleep.
[4]Some people have trouble sleeping, especially if they are nervous or stressed about something. Sleep experts say that it’s better not to try too hard to get to sleep, and certainly not to keep looking at the time. To have good sleeping habits, it’s better to sleep in a dark and quiet environment. It’s also good not to sleep too soon after eating, or after drinking too much water.
[5]The amount of sleep we need (74) ③________ different from person to person, though the average seems to be just under eight hours.

【推荐2】The earliest form of writing appeared about 5,500 years ago. In the past, hand writing was an important subject in school. Now, many students sometimes do homework on a computer and turn in their tasks online.
Many people think typing (打字) is quick and easy to read, while writing by hand may take longer than typing. But others say writing with a pen and paper is more valuable. Writing by hand has big advantages. Research shows that when we write down ideas with a pen or pencil, we make the brain active to help us learn, remember and think. Writing by hand lets people show their creativity. No two people have the same handwriting. Writing by hand can also help people concentrate. When using a computer, people can go online or play computer games easily.
Handwriting may be pretty. However, people can get their ideas and thoughts down more quickly when they type. Typing can also make it easier for people to change. Once something is written by hand, you can’t delete it. If you want to make a change, you have to write it all over again. What’s more, some people’s handwriting may be hard to read. Typing makes everything clear, and no one will have to worry about their words being clear enough.
