Many people think that water will never be used up（用尽）because there are many rivers and lakes. And the rain can make us get enough fresh water. Also, we can dig wells（井）to find fresh water under the ground. In fact, it is wrong and dangerous to think so. In some areas, people fight（争斗）for fresh water. There is little rain there all year round. Let’s look around us. Some factories pour（倒）dirty water into rivers. And some people drop litter into rivers. We see polluted water here and there. We must do something to help people understand about preventing water from being polluted. It’s never too late if we take action right now.

We have always been interested in the moon. 2000 years ago people already knew it moved 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(望远镜) 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 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 were finally 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 Earth. They believe very early in its history, maybe 4 million years ago, something about the size of Mars hit 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 though our ideas about the moon may change again, we will still be interested in it.
小题1:From the passage we know the moon was made of_____________.| A．earth | B．rocks | C．water | D．metal |
小题2:In the passage the writer wants to tell us ___________________.| A．why people are interested in the moon | | B．how ideas about the moon have changed over time | | C．where the moon came from in the past | | D．that people have finally learned the truth about the moon. |
小题3:Before 1969 most scientists thought the moon was ______________.| A．part of the earth billions of years earlier | | B．older than the earth | | C．a planet caught by the earth’s gravity | | D．made of the same things as the earth |
小题4:From this passage we can learn that ___________________.| A．scientists in the past were not clever | | B．the earth was once part of the moon | | C．we now know everything about the moon | | D．new information brings new ideas |

Taking away a city’s rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside of the city to a dump(垃圾站). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewagesystem takes away the used water from toilets, bathtubs(澡盆) and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles where they slowly change into something called humus(腐殖土), which looks like black earth. It is rich with kinds of things that feed plants and help make them grow.

In most parts of the world, many students help their schools make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clear.
Here are some things students often do.
No-garbage lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
No-car day. On a no-car day, nobody comes to school in a car--- not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jog, bike or run. Use your legs! It’s lots of fun!
Turn off the water! Do you know that some toilets can waste twenty to forty m3 of water an hour! In a year, that would fill a small river! In environment clubs, students mend those broken toilets. We love our environment. Let’s work together to make it clean.
