The idea of light pollution has developed with the increase of lights in cities. In many areas, this light makes it difficult or impossible to observe stars and planets in the night sky.

There are a number of reasons why light pollution is important. One has become clear at the Mount Wilson Observatory near Los Angeles, California. Today, light from Los Angeles makes the night sky above Mount Wilson very bright. It is no longer an important reasearch center because of light pollution.

Light pollution threatens to reduce the scientific value of research telescoples in other important observatories. They include Lick Observatory near San Jose, California and Yerkes Observatory near Chicago, Illionis.

Light pollution is the result of wasted energy. Bright light that shines into the sky is not being used to provide light where it is needed on Earth. Poorly designed lighting causes a great deal of light pollution. Lights that are brighter than necessary also cause light pollution.

Most people in America are surprised to find out that they are able to see our own galaxy(星系)，the Milky Way, with their own eyes. But about three­fourths of Americans cannot see the Miky Way because of man­made light.

Objects in the night sky are resources that provide everyone with wonder. But light pollution threatens to prevent those wonderful sights from being seen.

1.Light pollution usually occurs________.

A．in cities                               B．in the country

C．in wild areas                           D．in developing countries

2.Which of the following is TRUE according to the passage?

A．Mount Wilson Observatory is the most important one in America.

B．Light pollution affects observatories only.

C．In the dark night people can observe the sky clearly.

D．Astronomers can observe the stars clearly by the lights of the cities.

3.The victims affected by the light pollution are________.

A．children          B．grown­ups         C．students          D．observatories

We have to admit that many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment friendly products have actually contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced and these are difficult to get rid of.

However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they take action to buy a product, they ask questions like these “Will this shampoo add damage to the environment?” “Can this metal container be reused or can it only be used once?”

A recent study showed that two out of five adults now take the environmental safety of a product into account before they buy it. This means that companies must now adjust the way they make and sell their products to make sure that they are “green” that is, friendly to the environment

Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds of them advocating green. In addition, some supermarket products carry labels (标签) to show that the product is green. Some companies have adopted the manufacturing (生产) of clean and safe products as their main selling point and emphasize it in their advertising.

The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it.”　 The public pressure is on, and gradually business is cleaning up its act.

1.It becomes clear from the text that the driving force (动力) behind green products is

A. public caring for the environment　　 B. companies' desire for bigger sales

C. new ways of doing business　　 D. rapid growth of supermarkets

2.What would be the best title for the text?

A. Business and People　　 B. Business Goes Green

C. Shopping Habits Are Changing　　 D. Supermarkets and Green products

3.The underlined word "it” in the fourth paragraph refers to

A. a selling point　　 B. the company name

C. a great demand for health foods　　 D. the manufacturing of green products
