There are several causes leading to poor eyesight like not enough food, genes (基因) and aging (老化). Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight form UV rays.
Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly (定期地) and eats the right kind of food, his eyes will stay in good condition for a long time.

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.

When Oakland High School in California moved into a new building, the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts (专家) came to find the cause of the sickness. Finally, they discovered that the air in the building was not safe to breathe. They were surprised to find out that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards(合成板). This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化学物质). This is just one example of a modern problem that is most common in cities—indoor air pollution(污染).
People have worried about air pollution for many years, and the government has spent lots of money trying to clean up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows: Indoor air pollution is almost two to five time(倍) worse than outside pollution. So remember to open the windows and don’t stay too long in modern buildings with windows closed.
小题1:Many students and teachers _________ after they moved into the new building.

A fish that lives in America can live out. of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up, they live. on the land, said Scott Taylor, a researcher in Florida.                        
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
"We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.
"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land," Wright said.

Want to save the environment? You probably can’t fix everything on your own, but by taking small steps and keeping the environment in mind every day, you can make a difference,
1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off lights when you leave the room, turn off your TV when you’re not watching it, you’ll save energy. If you take shorter showers, you’ll save water.
2. Shop Green. Shopping is fun, but buying things you don’t need is wasteful and bad for the earth. Before you buy something, ask yourself how much you’ll really use it. Keep yourself away from buying products with unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those shipped from far away.
3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn’t the colour, it’s how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products made from environmentally friendly materials like organic(有机的) cotton, which is grown without the use of pesticides ( 杀虫剂).
4. Study Green. What’s better than learning about the environment? Save it while you learn, It can be as simple as using both sides of a piece of paper before you recycle it, or reusing an old textbook :instead of buying a new one. If you want to do more, join an environmental group at your school, and encourage your friends to join, too.
小题1:The underlined phrase "a vintage store" in this passage refers to (是指) a place where you can buy          .

How do you like to go to school like this one in Oxford, England? There are no real classes. The students go from one group to another when they want to. You may find students of fourteen, sixteen or twenty - one years old all in the same group. They work at their own studies. Nobody tells them what they should do or what they shouldn’t do.
The day I visited, school began at nine. Some students were listening to their own lessons. Others were watching TV on physics. A group was working in the library. I didn’t see anybody just sit doing nothing. Everybody was studying.
At lunch time I could see students working, too. They were talking about their lessons while they were eating. When you think of those students, you can be sure it is one of the best schools in the world.

Do you know that it is your own immune system working against the virus that makes you uncomfortable when getting a cold, but not the virus itself? So when you have got a strong immune system and the virus is strong enough too, you will possibly get terrible cold symptoms( 症状) ?
Vitamin C won't stop a cold
It is claimed that Vitamin C helps by increasing white blood cells. However, many tests have shown that it does not prevent colds. At best, it only slightly reduces the rime of symptoms.
Staying indoors won't protect you
One of the most likely sources of cold viruses is your computer mouse or desk. A study of the cold virus in offices found that 47% of desktops, 46% of computer mice and 45% of telephones had cold viruses on them.
Wrapping up warm won't protect you
Colds are more common in autumn and winter. That's because the cool, wet and cold weather drives people indoors, where viruses may more easily jump from one person to another. And the distinct peak in colds(感冒高峰) is in September and early January, which is likely due to the return of students to schools and colleges after the summer and winter vacation.
