                                     B 

       Is there intelligent (有智力的) life on other planets? For years,scientists said “no” or “we don't know”. But today this is changing. Seth Shostak and Alexandra Barnett are astronomers (天文学家) . They believe intelligent life exists (存在) somewhere in the universe. They also think we will soon contact these beings (人;生物) .

       Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. “This is long enough for other planets to have intelligent life ,” say Shostak and Barnett. The second reason is size—the universe is huge. “Tools like the Hubble Telescope (哈勃望远镜) have shown that there are at least 100 billion galaxies ,” says Shostak. “And our galaxy,the Milky Way,has at least 100 billion stars. Some planets going around these stars might be similar to Earth."

       In the past,it was hard to look for signs of intelligent life in the universe. But now,powerful telescopes (高倍望远镜) allow scientists to discover smaller planets —the size of Mars or Earth一in other solar systems. These planets might have intelligent life.

       Have beings from space already visited Earth? “Probably not ,” says Shostak. “It's a long way away. However,intelligent beings may contact us in other way,such as radio signals (信号) .In fact,they rxlay be trying to communicate with us now,but we don't have the right tools to receive their messages. However,this is changing. By 2025,we could make contact with other life forms in our universe and we might help each other.”

                                         B 

       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 to 30 years from now,according to the BBC.

       Digital money 

       We used to pay with cash (现金) for everything we bought. Now when we use a credit card (信用卡) to shop online,money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.

       When ATM cards were first introduced,they were not accepted everywhere. But now it’s  hard to live without them. It's reported that people in Sweden completely stopped using cash last year,and the US might be next.

       Bionic (仿生的) eye 

       It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.

       A blind eye can no longer sense light,but a bionic eye can use a camera to “see” the environment and send data (数据) to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution (高清的) image could be just a few years away.

       Self-driving cars 

       Unlike a human driver,a self-driving car won’t get distracted (分心) by phone call,the radio or something outside the window. Sensors (探测器) and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car driver itself. In the future,driverless cars would be widely accepted.

() 36.   has stopped using cash completely.

   A. Sweden   B. ATM   C. BBC   D. America

() 37. What does the writer mainly tell us about digital money?

   A. We use digital money to shop online without paying money.

   B. Digital money is most likely to be used instead of cash.

   C. Using cash is easier and safer than a credit card.

   D. ATM cards are always popular.

() 38. Which of the following statements is TRUE?

   A. Bionic eyes only appear in the science fiction film.

   B. Human drivers won’t get distracted by something outside.

   C. The blind wearing bionic eyes may see clearly in the future.

   D. There will be no road accidents at all if self-driving cars are used.

() 39. From the report,we can learn some information about   .

   A. culture and art           B. industry and farming

   C. science and technology    D. traffic and journey

() 40. Which of the following can be predicted (预测) from the passage?

   A. There would be a number of self-driving.

   B. The blind could use cameras to see things around.

   C. We would live a hard life with digital money.

   D. Robots would control the world.
