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. 样一个道理在新西兰留学， tears.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

The correct explanation about “plug-in” is _________.

A．a radio or TV connected with a computer

B．a small,add-on piece of hardware which improves your web browser

C．a small,add-on piece of software which can turn your computer into a radio or TV

D．a small,add-on piece of software like Netscape Navigator or Microsoft Explorer

When we go to a “shocked” website a second time,_________.

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

D．we have to buy the shockwave control and load it

Most of the time,how can we get a plug-in before automatic installation?

A．We have to buy it from the developer.

B．We have to borrow it from the developer.

C．We have to rent it from the developer.

D．We can obtain from the developer without paying.

WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.
The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.
“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.
That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).
Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.
“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.
“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”
In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.
Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.
What was the US Geological Survey intended to do?

A．To determine whether the polar bear was in danger.

B．To measure how fast the sea ice melts in the Arctic.

C．To check the predictions of the computer models.

D．To find out the exact number of the polar bear.

What causes the polar bears to disappear by 2050?

A．The pollution of the Arctic region.	B．The sea ice melting at high speed
C．Fewer food sources being left.	D．The temperature getting colder.

The key to preventing polar bears dying out seems to _______________.

A．help young polar bears to survive the cold winter

B．have large number of seals living in the oceans

C．make sure there is enough sea ice in the Arctic

D．provide chances for adult polar bears to reproduce
