Your computer has been playing music for years, one CD at a time. Now hundreds of songs can be stored in your PC if they' re in the MP3 format (格式).

What is it?

MP3 compressed(压缩) music into small computer files. You may download MP3 music several ways: Music can be downloaded from websites that have turned wide music libraries into MP3. Once MP3 music is on your PC’s hard drive, you can play it through your computer's speakers, "burn" it onto blank CDs or swap(交换) MP3 files with friends using e -mail.

How much?

Software needed to play and turn MP3 music is often free. Compact portable MP3 players start at around $ 40 and can hold hundreds of songs. A blank CD on which you can record music costs about a dollar.

Advantages

MP3 turns your home PC into a jukebox(自动唱机) . Small MP3 players are the size of a deck of cards(一副牌), making it easy to take hundreds of songs with you.

Disadvantages

You may find that some websites only allow you to listen but you can't download music. Others let you download music but can't be copied to MP3 players. And a growing number of new CDs make it impossible to copy songs to a computer.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.

To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威胁) our health, our happiness and our life.

Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工业) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.

Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.

Our increasing population is part of the problem. More people, more waste.

Where is this all to end? Are we turning the world into a big rubbish dump(堆存处)，or is there any hope that we can get rid of (摆脱，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.

The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.

1.Which of the following is NOT true according to the passage?

A. We live on the earth, so we should look after it.

B. Man is fighting against different kinds of pollution.

C. To pollute means to make air, water and land unfit for use.

D. All the waste produced by modern industry can be absorbed.

2.In Paragraph4, the underlined word “chemicals” mean ____________.

A. 化学物质 B. 医疗器械 C. 污染源 D. 塑料制品

3.Through the uncontrolled use of poison man has___________.

A. made the drinking water dirty B. polluted the land

C. killed the animals D. all of the above

4.From the sentences “More people, more waste.” We know that ___________

A. we need more people, not more waste

B. the increase of population caused more waste.

C. there isn’t any hope that we can get rid of the pollution

D. More people have been warned of the danger of more waste.

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

A. Man begins to understand the pollution.

B. Man doesn’t know how to control pollution.

C. Man is doing something to control pollution.

D. Man still doesn’t realize how serious pollution is.

What is color? Why do some of the things around us look red, some green, others blue?

Colors are really made by deflected (反射) light. We see color because most of the things reflect light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.

Some of the light is reflected and some is taken in (吸引) and turned into (变成) heat (热能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.

1.When something reflects light, we can _____.

A. see its color B. see its heat C. not see its color D. see nothing

2.Something looks white because it reflects _____.

A. some light B. no light C. all light D. most light

3.the dark-colored clothes are warm because ____ is taken in.

A. more light B. less light C. more color D. less color

4.In summer ______ make people feel cool.

A. dark-colored clothes B. red-colored clothes

C. green-colored clothes D. light-colored clothes

5.What’s the best title(标题)of this passage( 短文 )?

A. Dark color B. Color C. Heat D. Clothes
