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. 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 a dog loses a leg, the animal eventually figures out the best way to get around on three legs. In a short time, the dog learns to deal with its physical disability. Now, scientists have developed robots that behave in much the same way. We can find robots everywhere. Robots build cars, play chess and can clean your house. They may someday drive your car, too. Two robots, named Spirit and Opportunity, were sent to Mars on a mission to explore the red planet. Jeff Clune is a computer scientist with the University of Wyoming. He says robots also help people in natural disasters. Robots are deployed in search and rescue operations following an earthquake. They may someday also be used to examine the wreckage of a nuclear accident, like the one in Fukushima, Japan. Mr. Clune says robots can be sent to a lot of places said to be unsafe. "The problem is that all of those types of situations and environment are extremely unpredictable and dangerous. And it is very likely that robots and humans in those situations become damaged." He and other scientists are developing technology so that robots will continue operating after the first sign of injury. They want the machines to have the ability to make changes and continue performing until they can be repaired. Mr. Clune and researchers in France have added one more operation to the skill set of robots working under difficult conditions. They say they programmed a hexapod robot, one with six legs, and a robotic arm to learn how to deal with injury. Their findings were reported in the journal "Nature". Mr. Clune said that once the robots become damaged, they use their intuition and knowledge of how their body works to find a way to deal with the damage. He says the robots are also programmed with child-like curiosity. In other words, they are always asking questions and looking for answers. The whole process takes about a minute for the robots to find a way to overcome damage. According to the passage, nowadays robots can't _ . A) play chess or clean the house B) be sent on a mission to explore on the Mars C) help people in search and rescue operations following an earthquake D) examine the wreckage of a nuclear accident

Ques:One day a rabbit ran into an elephant. "Hello," said the rabbit. "Fine day, isn't it?" The elephant stopped to look down at the tiny creature and shouted. "Leave me alone. I don't have the time to waste on someone so small." The rabbit was shocked by the elephant's words. Then he decided to ask the whale what she thought about the elephant's rudeness. But the whale laughed at this tiny animal. The rabbit said, "You think that I am weak, but in fact, I am strong! I can beat you at Tug-of-War ."The whale looked at him for a moment before bursting into laughter. "Very well, little one. Go and get a rope," she said.The rabbit ran off to find a strong and thick rope. Then he went to the elephant, "Elephant, I will beat you at a game of Tug-of-War." The elephant laughed loudly, but agreed to challenge the tiny animal. He tied the rope around his huge waist. The rabbit took the other end and ran away. He called back to the elephant, "When I say 'pull', you start pulling. "The rabbit took the other end of the rope to the whale, "Tie this to your tail and when I say 'pull',you swim." The whale tied the rope to her tail after laughing at the rabbit's foolishness. Then the rabbit called out "PULL!" The elephant and the whale began pulling. After a while, they were too tired to continue. The elephant and the whale never knew how such a tiny creature could beat them. But from that day on, they said "hello" to the little rabbit with great respect whenever they met. Which statement is TRUE according to the passage? A) The elephant was pleased to talk to the rabbit at first. B) It was the whale who suggested having a game of Tug-of-War. C) The rabbit was stronger than both the whale and the elephant. D) The whale and the elephant began to respect the rabbit from then on.
