The earth is changing. Tomorrow it will be different. All the living things on the earth are changing. Even people are changing, and tomorrow you will be different.

There are many kinds of change, and many different things than cause change. People need to realize the changes, to learn to see them, and to learn what causes change.

Human beings must solve many problems so that they can continue to live successfully. War is one of these problems. Disease and natural disaster are problems. Having enough food and energy for the growing number of people in the world is a problem. Most problems can be solved, but some are impossible to solve. The way in which people solve problems affects how long and how well they can live.

We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.

When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.

In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.

After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.

In the future, even thought our ideas about the moon may change again, we will still be interested in it.

On a hot African morning, Leila was lying on her stomach and an elephant was walking towards her. Leila waited. Then she pushed the button on her camera. “And I got my best photo of an elephant ever, by lying under my car,” Leila explained. “I wanted to get close to the elephants, but of course this was dangerous; they had their babies with them. So every morning I used to park my car in the open near the path (小道). They used to take the same path every morning when they left the water hole. After a week, they were used to seeing my car. So the next morning, I lay under it and got my photo!”

Many of the best wildlife photos come from good planning. In Africa, photographers set up their hides (隐匿处) near water holes. They also set up hides near forest paths, as animals use the same paths every night. For bird-watching, many lakes have hides. Inside the hides, bird-watchers can watch all day in the shade (荫处) out of the wind and rain.

Good wildlife photos are needed for books, postcards, magazines and newspapers. But a success rate of 1 in 20 is good.

1.Why did Leila lie under her car on the stomach?

A. Because she wanted to sleep.

B. Because she wanted to take photos but was afraid of the animals.

C. Because it’s easy to see the elephants.

D. Because it’s very comfortable.

2.How can photographers take good photos?

A. By making good preparation.

B. By going into the forest at night.

C. By walking around the holes.

D. By going to the nearest lake.

3.What can we know from the last sentence of the passage?

A. The successful rate of taking wildlife photos is 50% at most.

B. Photographers who take wildlife photos need more practice.

C. To take good wildlife photos is not difficult.

D. It’s hard to take good wildlife photos.
