答案
答案略
A
① What will the world of tomorrow be like? Many people today believe that technology is going to help solve some problems we have today. New technology may solve old problems, and it may also create new ones. No technology is perfect. Each has advantages and disadvantages. Here are three examples.
② When we dream about the future, many of us think that we will be able to fly to the sky in our own flying cars. We could fly at 480 km per hour, avoiding traffic lights and busy roads. However, if too many flying cars are in the air, there will be trouble with traffic control.
③ 3-D printing is another new technology for the future. 3-D printers are already used to make life-size models of car parts部件, and man-made body parts, like ears. As we move into the future, 3-D printing will change the way we make things and the way we treat sick people. The disadvantage is that such a machine is very expensive.
④ Finally, people are trying to make a robot suit套装. This is an electronic suit. It allows people to lift heavy things and walk a long way. It might help people walk again after an illness or an accident. However, one disadvantage at the moment is the cost.
⑤ It is easy to imagine a future. We will be able to fly to work, print out a new pair of shoes or lift a car above our heads. Although there are some problems to solve, we can certainly dream of a new world. In this world, technology makes people's life easier and safer, and it can solve some of the most difficult problems we have today.
