Look at the Earth from.space.Why does our planet look so blue？Its blue because water covers almost three quarters of the Earth's surface.Water is not just an important part of our planet.It is an important part of our body，too.More than half of our total body weight is water.
Our body loses water whenever we exercise or.go to the toilet.That's why we need to drink plenty of water every day.We drink water.We use it to cook，clean，and carry waste out of our homes.Farmers use it to grow vegetables and crops like rice and corn；factories use it to make products.
Since the 1950s，the amount（数量）of water people use has increased by three times.But the water supply（供应）hasn't.Scientists worry that soon there won't be enough water for us，as well as for the animals and plants that share our world.What can we do to help？Use water wisely.
Having enough water isn't our only problem. We also need it clean.
Right now，ships and factories are putting wastes into seas，rivers and so on.Even chemicals that farmers use are running into rivers and lakes.All this pollution can make the water dangerous to drink.It can also harm fish and other water﹣living lives.
We must do something to stop pollution.It's the best way to protect our world's most valuable natural resource（资源）.

Isn't fast food delicious？Aren't fast food restaurants cool？ ...The answer to these questions is yes.
However，there are growing facts that fast food is one of the worst parts of modern life.And studies have shown that burgers and fried chicken，which we enjoy so much，can cause a lot of health problems.
In spite of （尽管） this，why are fast food restaurants so attractive（吸引人的）？The first and most important reason is that their service is fast.Their staff（员工）are friendly and very smart﹣looking in their clean and bright uniforms（制服）.Moreover，most fast food restaurants are near places that people always pass by.It is so easy to graba burger and eat on the way to work.

Such attractive places are selling junk food!Isn't it a pity？Is there a way to change the fast food restaurants into special places where you get the best possible，healthy and fresh food？
Well，why not？
As people realize the health problems that fast food causes，it is quite likely that fast food restaurants may go out of date.It may happen sooner or later.
Therefore，instead of resisting（抵制）fast food restaurants，a better idea may be to persuade（说服）them to change their menu!Fast food restaurants can be places to go to when you want to eat something that will be good for your body.If they could combine（结合）healthy food with their speed of service，delicious tastes and comfortable feelings，that will be the next best thing on the earth for the human beings!

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.The Mangrove Rivulus is a type of fish that_________.
| A．lives on land in Africa |
| B．can stay alive for months out of water |
| C．prefers living in dry places |
| D．is the longest living fish on earth |
Who will write a report on Mangrove Rivulus?

C. Patricia Wright. D. Scientists from Europe.According to the passage, lungfish can___________.
| A．breathe through its skin | B．be found in Asia |
| C．keep alive out of water | D．keep alive and walk on land |
Which one of the sentences below is not true?
| A．The Mangrove Rivulus fish can live out of water as long as other animals if it has something to eat. |
| B．Millions of years ago, animals began to live onto land from water. |
| C．Lungfish found in Australia, Africa and South America can live out of water in a not active way. |
| D．The walking catfish found in Southeast Asia can stay on land for hours at a time. |

| A．ft was made by Scott Taylor, a researcher in New york. |
| B．It was helped by an American magazine. |
| C．It was helped by Patricia Wright. |
| D．It was made by a researcher while travelling. |

Dolphins are our friends. They can use tools to solve problems although they don’t have hands. For example, scientists have ever found that a dolphin can make a shy eel(鳗鱼) come out of its hole with a dead fish.
Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (个别的) words, but also understand the importance of word order in a sentence.
Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.

Computers are useful machines. They can help people a lot in their daily life. For example, They can help people to save much time to do much work, and they can help people to work out many problems they can’t do easily.

We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones. A snail _________.
