In most situations, light helps us see. But nowadays humans are using too much of it so that it is in fact
a kind of pollution.
When it comes to looking at the night sky, too much light makes it difficult for us to watch some of life"s
most wonderful sights: stars, planets and even galaxies (星系).
According to scientific research, about 2, 500 stars can be seen by the human eye without using any
special equipment (设备). But because of light pollution, you can only see 200 to 300 stars from today"s
countryside, and no more than ten stars from a city. In most big cities, people cannot see the sky filled with
stars like they did in their childhood.
Light pollution affects more than just our view of sky. Research shows that lots of nighttime light can
harm wildlife, too.
When birds fly to another place over cities, they sometimes get lost by the brightness and fly in circles
(圈) until they drop from tiredness. Sea turtles (海龟) need dark beaches for laying eggs, but they can"t find
their ideal places because of those bright lights.
Too much light at night may even affect human health, but scientists are not sure of that. They are still
learning more.
In order to prevent things from going worse, governments and some organizations are working to reduce
light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used
only when and where they are truly needed. They also shine lights down at the ground instead of up into the
sky and use lower brightness levels.
Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will
live a peaceful and undisturbed life, too. |

China has decided to stop the use of free plastic bags. Supermarkets, shops and outlets (经销店) in
China can"t offer plastic bags any more.
Every year, people use too many plastic bags. They throw them here and there after they have used
them. The government has done its best to deal with them but failed. While we offer quick service (服务)
to customers, the plastic bags pollute water, earth and air, and they waste the oil. The government asks
people to go back to carry cloth bags and use baskets when they go to buy something. The cloth bags
and the baskets can be used again and again. Many months have passed. The environment has been
improved a lot. |

What is the biggest animal of all? The whale is. A blue whale weighs
more than a hundred tons.
Whales live in the sea, but they are not fish. They are mammals and must have air to breathe. The babies
drink milk from the mother"s body. Every spring, groups of whales swim hundreds of kilometers to warm
places.
Each group goes to the same place every year. The mothers take very good care of their babies. Whales
are a gentle kind of giant. They always live together and help each other. They "talk" to each other in the water
with a high noise that sounds like singing.
Yet people kill over a hundred whales a day. They kill them to make many things. The whale dies very
slowly and in great pain. Some ships kill every whale they can find, even mother whales and babies. If things
go on like this, there will be no young whales to grow up and no mother whales to have more young. | | 1. ______ are the biggest animals on the earth. | | [ ] | A. Elephants

people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is
becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert? Scientists think that people make deserts. People are doing
bad things to the earth.
Some places on the earth don"t get much rain. But they still don"t become deserts. This is because some
green plants are growing there. Small green plants and grass are very important to dry places. Plants don"t let the
hot sun make the earth even drier. Plants don"t let the wind blow the dirt away. When a little bit of rain falls, the
plants hold the water. Without plants, the land can become a desert much more easily. | | 1. Deserts _________. | | [ ] | A. get very little rain

protect it.
When Wang Boxuan, a Beijing high schoolboy, uses up his exercise books, he does not throw them away.
Each one is stored at his school with hundreds of exercise books given by other students. Then they are sold to
a Beijing paper making factory.
The paper is recycled and used again by students and teachers in the school. At the same time, the money
made from the sales goes towards schools in Inner Mongolia for planting trees and grass. This place is one of
the sources of the sandstorms that often attack Beijing during springtime.
Wang"s school is one of the schools in the capital that take part in the"green promise"environment protection
activity. So far, nearly 210,000 students have taken part in the activity, collecting more than 87 tons of waste
paper.
With the Olympic Games coming to Beijing in 2008, students are eager (渴望) to help make the capital a
more pleasant place.
"There are some environment problems in the city, such as sandstorms." said Wang. "We should do our duty
