We are changing the earth, the air and the water, and 19 that grows and lives. If we go on like this , we shall destroy ourselves.
What will happen in the future? Perhaps 20 is more important to ask “What must we do now?” The people who will be living in the world tomorrow are 21 young of today. A lot of them know that conservation is necessary. Many are helping to save 22 .
Now fifteen million young people in many countries are studying 23 and the country around him. In some countries they spend much time as “conservation volunteers.” They plant trees and help to 24 wild birds and animals.

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.

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 |

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. |
What can we say about the discovery of Mangrove Rivulus?

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’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 _________.
| A．moves more slowly at night | B．has thousands of feet |
| C．doesn’t move at all | D．sleeps much of the time |
In the sentence “A snail draws its body into its shell”, the word “draw” means _____.
| A．to make with a pencil | B．to push | C．to pull | D．to move away |
From the story, we know _________.
| A．a snail’s shell is very thin | B．a snail can’t see well |
| C．a snail’s nose is quite short | D．a snail’s body changes in different seasons |
A snail goes to sleep when _____.
| A．it feels hungry | B．it is put into a paper box | C．spring is coming | D．it rains heavily |
Which of the following is wrong?
| A．In winter the snail doesn’t eat or move. | B．A snail doesn’t like living under the sun |
