Right in the middle of the town are some long ponds(水池). They are only about half a foot deep. The men of Symi dug out the earth to make the ponds.
Over each pond is a low cover. It is made of glass that you can see through.
At night, sea water is taken into the ponds. The next day, the hot sun shines through the covers. The sun light turns the water into vapor(水蒸气) and the vapor goes up from the ponds. The salt is left behind.
As it goes, the vapor became mist. On the inside of each cover, the little drops of mist run together to make big drops. These drops run down the sides of the cover, filling other ponds with fresh water.
The salt left in the ponds is washed out each night. Then more sea water is taken in. The factory is ready for the next day’s work. The covers and other parts of the factory cost very little. Sea water and sun cost nothing. Most people of Symi are poor. So to them this new way of getting fresh water seems wonderful.
小题1: Where are the little drops made into big drops?| A．On the inside of the covers. | | B．In the ponds with fresh water. | | C．On the walls of the salt water ponds. | | D．Between the fresh water and the salt water. |

The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won’t be used up.
小题1:The world is thirsty for water because _______.| A．we don’t have enough fresh water | B．a lot of water goes into sewer systems | | C．only 70% of the earth’s surface is water | D．sea water is widely used rather than fresh water |
小题2:From this passage, we know acid rain _______.| A．is only bad for living things | B．is not bad for buildings and factories | | C．can be produced in factories | D．is bad for people, animals, plants and buildings |
小题3:One difficult way we can solve the problem is to _______.| A．use the water with salt in it | B．remove the salt from sea water | | C．get water from underground | D．reuse the water in cities |
小题4:What is the best title for this passage?| A．Fresh water and sea water | B．A thirsty country | | C．The importance of water | D．The world’s water problem |

Can you imagine a classroom without one thing that has long been considered a necessary part? No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seem to run out of ink at the critical moment.
A “Paperless classroom” is what more and more schools are trying to realize. Students don’t do any handwriting in this class. Instead, they use hand-sized or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they’re studying, from maths to social science.
A high school teacher, Judy Herrel in Florida, US, described how her class used the Web. “Using a book that’s three or four years old is impossible,” she said.
A paperless classroom is a big step towards reducing the waste of paper.
“Think about the money and trees we could save with the computers,” she said.
But, with all this technology, there’s always a risk that the machines will break down. So, in case of a power failure or a technical problem, paper textbooks should still be widely available (可得到的) for these students.
小题1:The underlined word “critical” in the first paragraph probably has the same meaning as _______.| A．worrying | B．dangerous | C．happy | D．important |
小题2:You are sure to find __________ in a paperless classroom.| A．pens | B．computers | C．test papers | D．notebooks |
小题3:According to Judy Herrel, __________.| A．the Web can talk the students everywhere | | B．the Web can take the place of teachers | | C．the Web is a better tool for information | | D．the Web is for downloading information |
小题4:The paper textbooks should still be widely available because __________.| A．students won’t have trouble with their pens | | B．computers may break down sometimes | | C．students may not get all information from the Internet | | D．paper textbooks may give students more information |

Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no medicine, either.
Life today brings new problems. One of the biggest is pollution. Water polluti on has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is t he most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly .
Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
Ru les are not enough. We should do our best to fight against pollution.
