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.

     Every December, our nation's roads and skies are filled with travellers during the holidays. Many of those
travellers will   1   their pets at home, perhaps because the animals are more   2   inside their familiar walls than

     Pet sitters do much   6   than provide your pet with food and water while you're away from home. A good

plants, turning lights on and off, and providing with a lived-in look to avoid break-ins.

kennel, who takes care of your pet? If you're like many other pet  12 , you ask a friend or neighbor to stop in
and pour some soup and water in your pet's bowls. But is this the best for your pet? There's a good  13  that
your friends and neighbors do not have proper pet-care experience and have even forgotten to  14 . They may
also hate frequent requests to look after your pet while you're gone. So what is the solution? Consider hiring a
"pet sitter"-a professional, qualified person  15  to care for your pet.
    A pet sitter offers both you and your pet many benefits.

Why should I teach my children history? That sounds like a stupid question to even ask．But, as I hear different home schooling teachers discuss history, I get the idea that there may be different reasons for teaching history．Let me briefly explain the three good reasons for studying history and two bad reasons for studying history．

The major reason I see for studying history is that we can learn from the past．I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the thifigs that made these successes and failures．However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don't seem to learn from history．" Perhaps at least in teaching history, to my children I can do a small part in changing this．

A second major reason for studying history is that it is hard to understand the current political climate in the absence of an understanding of its historical context．We can- not even understand why we are and where we are without history, much less （更不必说） try to figure out where we are going or how we should get where we want to be．

I teach my children history, for one more reason．I purchased a set of historical audio （录音机） tapes for our children．My seven-year-old son listened to them over and over．It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himself．I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr．if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished．I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for．

1.What message can we get from the underlined sentence in Paragraph 2 ?

A．Many people aren't clever enough to learn well from the past．

B．Many people fail to make good use of history and make the same mistakes．

C．Many people feel it hard to understand history．

D．Many people have no interest in studying history．

2.In Paragraph 3, the author shows that history is useful because _______________．

A．it makes the current political situation go smoothly

B．it helps us realize the importance of historical events

C．it helps us understand why things are the way they are

D．it helps people accept the present situation where they live

3.Some historical figures are mentioned in the last paragraph to show ______________．

A．people can be inspired to do good, while also learning to fight against evil

B．people may also learn from bad historical figures

C．more celebrations should be held to honor their achievements

D．today’s people can also achieve what they achieved

4.What would be talked about in the following paragraph?

A．How to teach history effectively．

B．Some negative reasons for studying history．

C．How to get more people to study history．

D．Some bad historical figures．

5.The main purpose of this passage is to ____________．

A．ins[me the parents to teach their children history

B．show the importance of history in politics

C．explain the reasons why children study history

D．introduce the writer' s own way of teaching history
