In 1998, a British scientist named Kevin Warwick did an experiment. He inserted a small microchip into his left arm. He used the microchip to turn on lights, work with his computer, and even start the water for his bath. After only nine days, Warwick removed the microchip from his arm. Nine days is not a long time, but it was enough to give the world a very important message. It is possible to have a microchip in your body. Many people think that someday, we all will have microchips. There are all kinds of things that a microchip could do. It could be useful for simple, everyday things. You might not have to carry keys, because you could use your microchip to open the front door of your house. You might not need cash, because you could use your microchip to buy things. A microchip might be able to do more important things. For example, a microchip could contain all of your important health information. If you had an emergency and went to hospital, doctors could read your microchip and learn all of your health history. Some scientists even believe that someday a microchip could help cure diseases. Many people dislike the idea of a microchip in their body. They have a lot of concerns. Is it safe? Could a microchip make you sick? Besides, would other people be able to read your microchip and steal your personal information? People are especially worried about personal freedom. This is probably the biggest reason why so many people are against these microchips. What if your government could use your microchip to watch you? What if your government could use your microchip to find your location? Do you want the government to have that information about you? Again, for most people the answer is “no”. Nobody has microchips in their body yet. We don’t know if this will ever happen. If we ever do have microchips, we don’t know what they would look like or what they would do. What do you think? Would you like to have a microchip inserted into your body? Question 36: What does the passage mainly discuss? A. The disadvantage of using microchips B. The microchip in the body C. The advantage of using microchips D. Why people hate using microchips Question 37: The word “message” in paragraph 1 is closest in meaning to ______.
