The trees have been on the earth for millions of years. 1. Disease(疾病) is destroying trees. For example, in the 1970s, many trees in Europe were killed by disease.
2. This new danger attacks all the forests and woods of Europe from northern Sweden to southern Italy. First the branches turn yellow and brown. Then the trees’ leaves fall. The roots and the trunk shrink(萎缩). Finally the trees die. In the Black Forest in southern Germany, 75％of the trees have been destroyed or killed．
3. Nobody knows exactly, but it is probably air pollution or acid rain(酸雨). Factories, power stations and cars give off tons of smoke with acid into the air. Sunlight turns these into something harmful which fall with rain or snow onto the trees.
What can be done about acid rain? 4.
Acid rain doesn’t always fall on the countries which produce the pollution. The wind carries it from one country to another. Badly, the governments don’ t want to spend money on it if it won’ t harm the trees in their own countries.
5. The rainforests of Asia and South America are being cut down for firewood and building materials. Something must be done. If the trees die, we will, too.

Scientists think that there has been life on the earth for hundreds of millions of years. However, we haven't found life on other plants yet. Why not?
The Earth is a planet and it goes around the Sun. Seven other planets also go around the sun. None of them has an environment with air, so people and living things cannot grow. The Sun and its planets are called the solar system(太阳系). The solar system is a small part of our galaxy（星系）.
But scientists have discovered many other galaxies in the universe. But they are far away and their light has to travel for many years to reach us. It is hard to understand how large the universe is.
So far, scientists have sent lots of spaceships to look at other plants in our solar system, and some spaceships have gone beyond the solar system. However, no one has discovered any life in space yet.
But why has no one from other plants sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We don't know yet.
1.How many planets go around the sun?
A.Seven B.Eight C.Nine D.Ten
2.In order to look at other planets in the solar system, scientists have sent many________.
A.e-mails B.planes C.spaceships D.messages
3._______ has found life on other planets.
A.No one B.A scientist C.A traveler D.A student
4.Which of the following is TRUE?
A.All the planets have an environment with air. B.It’s easy to know how large the universe is.
C.There is only one galaxy in the universe. D.The solar system includes the sun and its planets.
5.The best title of this passage should be ________.
A.The Moon B.The Solar System C.The Stars at Night D.The Sun

Scientists think that there has been life on the earth for hundreds of millions of years. However, we have not found life on any other planets yet.
The earth is a planet and it goes around the sun, which is a star. Seven other planets also go around the sun. None of them has an environment like that of the earth, so scientists do not think they will find people and things on them. The sun and its planets are called the solar system (太阳系). The solar system is a small part of our galaxy (星系). There are billions of stars in the Galaxy, and our sun is only one of them.
Scientists have also discovered many other galaxies in the universe (宇宙). They are very far away and their light has to travel for many years to reach us. So how large is the universe? It is impossible to imagine.
Scientists have sent spaceships to the planet Mars (火星) to take photos. They have even sent spaceships to travel outside the solar system. However, no spaceship has travelled far enough to reach other stars in our Galaxy.
Scientists have always asked questions: with so many stars in the universe, are we alone, or is there life out there in space? Have there been visitors to the earth from other planets? Why has no one communicated with us? We do not know the answers… yet.
根据短文内容，判断下列句子正误。正确的用“A”表示，不正确的用“B”表示。
1.There are eight planets in the solar system.
2.There is more than one galaxy in the solar system.
3.The light from the stars in other galaxies has to travel for a long time to reach the earth.
4.Spaceships have visited most of the universe.
5. Scientists have received many messages from space.

The earth is 4 600 million years old. We humans have lived on earth for only 35 000 years, but during this period we have changed our planet a lot in many ways. Some things we’ve done are very good for the earth while some are bad.
All over the world, people have cut down millions of trees. When it rains or when the wind blows, the earth is taken away. Forests have become deserts, so more and more sorts of animals and plants are disappearing.
In big cities, cars and buses have polluted the air. Many people in cities now have health problems.
Factories have also polluted the land and the water. As a result, many rivers and lakes are now dead.
Around the earth, there’s a special kind of oxygen called “ozone”(O3). It is important to the earth. But now air pollution is destroying it and that has made a very big hole in the ozone layer. Too much harmful radiation from the sun passes through the hole and reaches the earth directly. This is very dangerous because this kind of radiation can cause cancer.
Carbon dioxide (CO2) in the air has increased a lot. It mainly comes from burning oil, coal and wood. This has formed a “blanket” around the earth. The heat from the sun can’t escape so the temperature is rising. This is called “the greenhouse effect”. It causes the level of the oceans to rise and the climate of the earth to change.
All these problems are very serious, so we must do something now.
根据短文内容，从题中所给的A、B、C、D四个选项中选择最佳答案。
1.What does our planet mean here?
