A rain drop fell to the ground on the side of a hill. The rain drop ran 1 the hill into a small river. The small river 2 the rain drop to a big river. There the rain drop travelled 3 to the east and mixed itself with salt of the sea. The sun shone brightly. It warmed the water on the surface of the sea. Though the water became warm, some of it turned into water vapor.
So 4 the water of the rain drop. The water vapor 5 the sea and went into the air. It do not carry the salt.
The cold air 6 the warm air 7 above the ground. The warm air became cool when it went up. 8 the water vapor of the rain drop turned into small drops gathered bigger and bigger drops. At last they became so big that they were too heavy to 9 in the cloud, and they 10 to the ground. So the rain drop would start another trip to the sea.

Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.
And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.
We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.
These small pieces have been going round the sun ever since. They are the planets.

Have you ever beard of Iceland? Iceland is a country, one-tenth of which is covered with ice. However, it is said that Iceland is the land of heat. Smoking volcanoes (火山), white steam (蒸汽) and hot springs are more amazing than the other sights including ice there.

It has taken millions of years for volcanoes and lava flows (熔岩流) to build Iceland. When hiking through one of Iceland’s many ancient lava fields, you may notice something strange. White steam is rising from each vent in front of you. Iceland is covered with vents which steam can pass out of. The steam comes from naturally heated rocks and hot water below the Earth’s surface (表面).

Like steam vents, hot springs can be seen here and there in the ancient lava fields. Blue Lake is the most famous hot spring in Iceland. It isn’t far from the capital city of the country. The water and white earth in it can make your skin as soft as a newborn baby’s skin. Enjoy that water, because it has traveled a long way. It starts nearly two kilometers under Blue Lake. There, water from the ocean continues moving up slowly into the spaces between hot rocks below the surface. And then the water is heated by hot rocks. Powerful machines and long pipes (水管) help bring the heated water to the surface. People in Iceland use natural hot water for hot springs. Besides, they use it to create electricity that can be used to heat homes and even greenhouses.

Iceland is one of the few places on the Earth where active volcanoes lie below ice. Heat from the volcanoes creates a strange and wild beauty. Therefore, some people believe that it’s better to call the country “Heatland” instead of Iceland. If you have a chance to travel there, take it.

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.

The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.

A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.

At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.

Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.

People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.

1. What did scientists find in September 2010?

A. A planet with water. B. A planet similar to the earth.

C. A planet without life. D. A planet near the earth.

2.According to the article, Gliese 581g ________.

A. is at the right distance from its star B. moves around the earth

C. is as far away from us as the moon D. can be reached in about 220 years

3. Paragraph 5 is mainly about ______.

A. the possibility of living on Gliese 581g

B. the kinds of chemicals around Gliese 581g

C. the way of looking for life on Gliese 581g

D. the aim of studying the radiation on Gliese 581g

4.Which of the following is the best title for the passage above?

A. Gliese 581g, a Likely Living Planet B. Gliese 581, a Likely Living Planet

C. Gliese 581g and Its Star D. Gliese 581g and Radiation

What will the house of the future look like? Architects (建筑师) believe that there are all possibilities. The only thing for sure is that the house will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface (表面) of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” of the house is deep under the ground.
The lizard (蜥蜴) house
Like a lizard, changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney can be a useful air conditioner because it is easier for hot air to flow out at the chimney.

1.
We can heat water, produce electricity or create fresh air for the home _________.
1. A.
  with a leaf from the tree
2. B.
  with the energy from sunlight
3. C.
  with gardens on its wall
4. D.
  with the door in the house
2.
What will happen to the cover of the lizard house when it’s in the bright sun?
1. A.
  It will take in light.
2. B.
  It will produce energy.
3. C.
  It will turn dark.
4. D.
  It will turn white.
3.
People can’t plant __________ on the outside wall of the house according to the passage.
1. A.
  tomatoes
2. B.
  potatoes
3. C.
  carrots
4. D.
  green tea
4.
What’s the passage mainly about?
1. A.
  Future life
2. B.
  Green house of the future
3. C.
  Different houses
4. D.
  Energy saving in the future
