Life on-line can be a much richer experience when you aren’t restricted to just written words and still pictures.Even if you’re new to the Net,you’ve probably heard about multimedia on-line—listening to audio,watching animations and videos,even playing in three-dimensional space.Sound and movement make information come alive.

To experience it,you’ll need special pieces of software called plug-ins.The term “plug-in” refers to a small,add-on piece of software which extends the capabilities of your web browser,like Netscape Navigator or Microsoft Explorer,turning your computer into a radio or TV.

When you arrive at a web page which contains a file requiring a plug-in which you don’t have,you will usually receive a message asking if you want to get it by downloading it and installing it into your computer.Most of the time,the installation will be automatic.

Occasionally,you’ll run into a downloaded file which needs to be decompressed or un-zipped before installation.Once installed,plug-ins run automatically,without you having to do anything.

Many multimedia controls still need to be obtained from the developer but are installed automatically.

Shockwave is a good example of this.All you need to do is go to the Macromedia site and click on the link to install the ActiveX control.The rest happens automatically.The next time you go to a “Shocked” website,the Shockwave control loads and plays the movie.

Most plug-ins and controls can be downloaded for free on the Internet,although not all will work with every system.Some of them,for instance,only work with Windows 95.

Plug-ins can help us to do all of the following except _________.

A.listening to music

B.watching animations and videos

C.playing three-dimensioned games

D.searching for information on the net

A.we should go to the Macromedia site and click on the link to install the Active X control

B.the shockwave control loads itself and plays the movie for us

C.we will be asked whether to download the shockwave control or not

The United States is trying to improve an edueation system that produces millions of citizens who cannot read, write, or add—let alone finding their country on a map.

In his first State of Union message since taking office a year ago, President George Bush promised to wipe out illiteracy(文盲) in the next decade and declared that“by the year 2008, U.S students must be first in the world in math and science achievements. ” They have a long way to go. American students were placed 14th in a recent general science test conducted in 16 countries. In a separate survey of chemistry students, the United States came 12 out of 14. In a mathematics test, they were last. According to Bush, there are 17 million illiterates in this country of 245 million people. Other estimates put the number as high as 23 million. In percentage terms, that ranks the United States alongside Niearague and below Cuba. “This nation,”Bush said in his State of the Union address, “will not accept anything but excellent in education.” Bush, who has declared himself “Education president”, and senior officals of his administration are warning that the United States will be unable to compete in the world without an educated workforce.

How to increase educational standards is a matter of debate in a country whose schools have no uniform national curriculum and are subject to a confusing variety of state and local controls. Most experts think that the problem lies at the elementary and high school'levels rather than with universities-but even their graduates show huge gaps in general knowledge. Among the root causes most frequently mentioned in education debates is the low respect in which U.S. society holds teachers-in contrast to Japan and Germany. In Japan teaching is a profession of high prestige(威望) and high pay. In the United States teachers are near the bottom of the society.

A.the United States ranked 12th not 14th in the chemistry test

B.the United States ranked 12th in the chemistry test conducted by 14 countries

C.the United States progressed from 14th to 12th in the chemistry test

D.the United States ranked 12th in chemistry test and 14th in general science test
