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.
But everyone, 25 young people, must work to save our world.

Scientist Without Laboratories
When you hear the word “scitentist”, what do you think of? Many people think scientist are people in clean white coats who work in labs. And some scientists do work in labs. But there are 26 scientist who work in woods and jungles. These scientists are called “animal behavior (行为) scientists”, and they study animals as they live in nature.
Why don’t these scientists catch animals and study them in zoos? The 27 is in the word “behavior”. Animals behavior scientists want to learn 28 animal behave in their wild homes. When animals live in cages (笼子) or in zoos, they do not act the same as they do when they are 29 . They may fight 30 each other, or they may not eat, or they may not raise (抚养) their babies as they usually would. To see real animal behavior, scitentists must go where the animals 31 .
So animal behavior scientists go into the jungles, the woods or the desert. There , their most important 32 are their eyes and ears. They watch and listen to the animals very 33 . They write down everything that happened in notebook. 34
they live near the animals, the scientists are careful not to frighten them. If the scientists are luncky, the animals will 35 no attention to them. Then the scientists can see how the animals really live.
The behavior scientists hope what they’ve learned about animal behavoir can provide clues (提供线索) to help people learn to live together more happily.

For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature— what people are (41) with— that decides what they will be like? (42) is it nurture —what(43) to people when they are born —that decides what they will be like?
Scientists have been studying twins to (44) if they can find the answer, because twins start out with the (45) DNA. Sometimes twins don’t live together at birth and grow up in different (46) and different places— so the nature is the same for both, but the nurture is different.
When scientists (47) these twins in their later life, they some times find some surprising (48).
Jim Springer and Jim Lewis were adopted(收养)by two different families at birth. They first met each other again thirty-nine years (49) and discovered they had a lot in (50). Both had been (51) twice. Their first wives were both named Linda and their second wives were both named Betty!
Each twin had a son — one called his son James Alan and the (52) called his son James Alan, too. Their children each had a dog called “Toy”. They even arrived at their first (53) in the same color of car.
So far twin (54) seem to show that both nature and nurture are important. What we have from birth, and how and where we live help to build (55) we are.
