A
What’s going to happen in the future Will robots control our planet Will computers become smarter than us Not likely. But here are some things that scientists say are most likely to happen in 10-30 years from now, according to the BBC.
Bionic（仿生的）Eyes
They are no longer something, only in a science fiction movie. People who are blind may have a chance to see things clearly—by wearing bionic eyes.
A blind eye can no longer sense sight, but a bionic eye can use a camera to “see” the environment and send information to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A bionic eye with very clear pictures could be just in a few years away.
Digital Money
We used to pay with cash for everything we bought. Now we can use Wechat Pay or Alipay to shop, money is spent without seeing it. That means we are already using digital money. People only need to take a mobile phone wherever they go. Using these ways is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.
It is reported that people in Sweden completely stopped using cash last year, and the US might be the next.
Self-driving Cars
Unlike a human driver, a self-driving car won’t be influenced by a phone call, the radio or something outside the window. Sensors（探测器）and cameras on the car would allow it to follow the rules of the road strictly and keep a safe space from other cars. This would greatly make the number of road accidents smaller. You can even take a short rest while the car drives itself. In the future, driverless cars would be widely accepted.
31. Which of the following payments is not mentioned in this passage
A. Cash B. Wechat Pay C. Alipay D. Credit card
32. Bionic eyes send information to the ______.
A. mind B. camera C. computer D. heart
33. From the report, we can learn some information about ______.
A. industry and farming B. traffic and journey
C. science and technology D. culture and art
34. The passage tells us that ______.
A. bionic eyes only appear in the science fiction films
B. the blind wearing bionic eyes may see clearly in the future
C. self-driving cars will be influenced by something outside
D. there will be no accidents at all if self-driving cars are used
35. We can infer（推断）______ that ______ from the passage.
A. there would be a number of self-driving cars on the road
B. robots would control the world
C. the blind could use glasses to see things around
D. we would live a hard life with digital money
B
A new report shows what life might be like in 100 years from now. The report is from a company. It asked experts on space and architecture（建筑学）, as well as city planners, to give them the life in 2121. They said the way we live, work and play will be totally different from how we do these things today. The experts used the Internet as an example. They said that 25 years ago, people could not imagine how the Internet and smartphones would change our lives. The Internet has completely changed the way we communicate, learn and do daily things. The experts said the changes in the next century would be even more unbelievable.
Researchers questioned 2,000 adults about the prediction（预言）they thought would probably happen in the future. They thought that in the future, few people will go to an office but will work at home and have work meetings online. People will have highly developed 3-D printers that will send you a design for furniture or a food recipe（食谱）and then “print” the sofa, table or pizza at home. There will also be less need for visits to the doctor. We will all have a home health instrument that will tell us what the problem is and make us healthy. We will also be going into space for holidays and to get energies that we have used up on Earth. A prediction that is not mentioned is whether people will need to study English or not.

A. the Internet was often used B. the Internet has developed fast
