We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.

New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大坝) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(镶板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.

AN ice ball shoots across the night sky, lighting up its path along the way, like a flying sun.
Ancient humans were afraid of the sight of comets(彗星). Many cultures believed that comets were messages sent by gods, and people thought these messages were warning signs for bad behavior. But today science and technology give us a better understanding of comets.
Last week, comet Ison ended its million-year-long journey as it flew straight toward the sun, melting most of the comet. It was hoped that comet Ison would survive this trip around the sun. Because once it got near Earth, it would have produced a great show of lights for us.
In ancient times, the coming of comet Ison might have scared people. However, now we can track a comet’s journey in our solar system. We can also study what they’re made of. There is even a project to launch a spacecraft onto a comet to study them further.
Although from the sky they look like great giant fireballs, comets are a collection of gas, ice, dust and small rocks. As a comet goes into our solar system, the sun’s solar winds blow some of the dust and gas away, giving the comet a tail. The average size of comets is about 10 kilometers in diameter(直径). But amazingly, their tails can be 150 kilometers long! Comet Ison’s diameter was about 5 kilometers.
Today, people don’t fear comets as much as they did before. Western countries have even developed and old tradition. When people see a comet or meteoroid(流星) shooting across the sky, they call it a shooting star, People who get the chance to see one get to make a wish. It is a tradition that lives on today.
小题1:In ancient times, people thought comets were _____.| A．warning signs sent by gods | | B．lucky signs for good behavior | | C．great shows of lights | | D．flying suns |
小题2:We can tell from the third paragraph that comet Ison ___.| A．finished its long journey to Mars | | B．survived its trip around the sun | | C．has reached the Earth | | D．was melted by the sun |
小题3:When a comet travels near the sun, some of the __ will be blown away by the solar winds.| A．gas and dust | B．ice and rocks | | C．dust and rocks | D．rocks and tail |
小题4:According to the last paragraph, what tradition lives on today?| A．Being scared by comets and meteoroids. | | B．Making a wish when seeing a shooting star | | C．Launching spacecrafts onto comets to study them further. | | D．Having a better understanding of comets |

Cities and towns in 35 countries took part. The year 2012 saw 6,950 towns and cities in more than 152 countries took part in Earth Hour movement. Last year 7,000 towns and cities in more than 154 countries took part in Earth Hour. This year, WWF is calling for people across the world to take part in Earth Hour 2014 – the biggest switch-off in history.
For the eighth year, people are being asked to turn off their lights for one hour to call attention to the issue of climate change. The WWF’s organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights.
Earth Hour supporter Jamie Oliver has some great ideas of his own for helping the environment: “We can all make simple changes to help, like always choosinghigher-welfare(规模化养殖的) meat, and even trying to have a couple of meat-free days a week. More little steps, such as taking a shower instead of a bath, leaving the car behind and walking to work, not leaving electrical appliances on standby（备用的） and so on are the beginning of a low carbon lifestyle and a healthier world.
This year, Earth Hour is asking people to take the movement “beyond the hour”. Earth Hour is a call to stand up and get involved. We hope everyone will join us in turning off for a brighter future.
小题1:What’s the main idea of Paragraph 1?| A．The first Earth Hour movement | | B．History of Earth Hour and its tasks. | | C．Earth Hour has changed our lives. | | D．Everyone can make a difference. |

It is December 25th, 2050. The people in the city are all celebrating Christmas. I’m the mayor of our city. My citizens and I are holding a big party under the sea, though you wouldn’t believe it. But please do not feel excited, you should feel sad because we have to live under the sea. Because of the pollution, the earth has been completely destroyed, from top to bottom. The atmosphere has no oxygen and moisture. As a result, the plants are burned by the strong sunlight with a great number of harmful rays. Of course, none of them are still alive. Not only no green, but also the temperature reaches about 121℃ all day even in winter because there is too much CO2 circling the earth.
On the land, there is no life. Luckily, the sea is not destroyed by human. So, we have to move into the sea. At the bottom of the water, people have built many new cities. There is a lot of advanced(高深的，先进的) equipment in each city. Computers are used to control all the machines, even the people’s life. We can also make the seawater into fresh water. There are two machines making oxygen. If they stop working for only one minute, more than 10 million people will die.
The population of our city is over 30 million and, of course, it is quite crowded. We have lots of high buildings and bridges. The roads are wide, too. Our cars are small UFOs, don’t be surprised, it is true. At the bottom of the sea you can’t see anything, because there is no light all day. However, we have advanced lighting equipment so that we can see the “sun” under the sea. Of course, the advanced lighting equipment is very expensive. And if it doesn’t work, we can see nothing under the sea. What should we do then?
