三、阅读理解(本题共 40 分，每小题 2 分) A

In the modern age, human society runs on energy. Most machines need electricity to operate. Humans can not live without electricity even a single day both in their daily life and work. They have many different ways to create electricity. But some ways are harmful to the environment.

For example, fossil fuels(化石燃料) are the most common kind of energy. They include coal, oil,

and natural gas. First, people have to dig them from the ground. This can sometimes harm the environment. However, scientists are creating cleaner and better ways to do that these days. So the environment is not harmed as much as before. But when people burn these fossil fuels, they can give off a lot of harmful gases, which is considered to be one of the greatest causes of global warming. This might harm the environment.

Tidal( 潮汐) energy is another way to make electricity. This uses the ocean tides to make

electricity. But some kinds of tidal energy can kill many fish and other sea animals. Also dams(大坝) can create lots of clean energy. But dams create lakes and change the way that rivers run. So they can do great harm to the balance of nature around the lakes and along the rivers.

Nuclear(核) energy is a very powerful form of energy. It is cheap. It is also very clean. But many

people are afraid of it because it uses radioactive(放射性的) materials. Also, there have been some very serious accidents in the past which caused great harm both to human and nature. But the technology is much better these days. So many countries are starting to use nuclear energy more.

( )41. According to the passage, which of the following is TRUE about fossil fuels?

A. They are dug from the ground. B. They are considered expensive.

C. They hardly harm the environment. D. They are not widely used in the world.

( )42. From the passage, we know that tidal energy can ．

A. cause serious accidents B. change the way that rivers run

C. give off a lot of harmful gases D. kill many living things in the ocean

( )43. Nowadays many countries start to use nuclear energy more because ．

A. it’s a common kind of energy B. people are not afraid of it now

C. it’s cheap, clean and safer than before D. people can’t live without nuclear energy

( )44.The passage is probably in the part of in a newspaper.

A. health B. science C. culture D. sports

B 人工智能——AlphaGo

Who is smarter, human being or artificial intelligence(AI, 人工智能)? The question swept the world a few months ago. In March 2016, AlphaGo, an AI program developed by Google, had the

Go( 围棋 ) match with Lee Sedol, a South Korean Go player. He is the world top player of this old

Chinese game.

In October 2015, AlphaGo became the first computer program to beat a professional( 职业的)human Go player. And this time, it beat Lee Sedol 4－1.

In fact, before the match, most people believed that Lee would certainly be the winner, because they didn’t think that AI was good enough to beat the human mind. However, the result was disappointing. As a machine, AlphaGo would never get tired, while Lee Sedol was only a human and humans must have some weaknesses.

AlphaGo’s wins over a human champion(冠军) show that computers can do more difficult tasks.

Some people may worry whether computers are now smart enough to beat us at everything. But scientists say that is not the case. Real life problems can be more difficult than the Go game. Thomas Johnson, a scientist of AI said, “It’s not hard to get a computer program to remember and produce facts. What is hard is getting computers to use knowledge in everyday situation.” And we believe we can use the technology of AI to improve the world.

( )45. The match between AlphaGo and Lee Sedol is mentioned at the beginning of the article mainly to A. get the reader to think about AI B. draw the reader’s attention to AlphaGo

C. show how AI is usually tested D. tell the reader AI has over the human brain

( ) 46. What was the result of the match?

A.Google program beat AlphaGo. B. Lee Sedol won AlphaGo 4－1.

C.Lee Sedol was beaten. D. Neither side won the match.

( ) 47. —Why did most people believe Lee would be the winner? —Because ．

A. computers had weaknesses and also got tired B. AlphaGo only beat a human Go player once

C. the Go game was invented by Chinese people D.computers were not so smart as a human

( ) 48. What does Thomas Johnson probably agree with?

A.AI does better than humans in every situation. B. It’s hard for AI to beat the human at everything.

C.The development of AI could be harmful one day. D.AI should be used to help us make difficult decisions.

Maybe you think that many parents have a lot to learn about what their children are doing online. According to a recent survey by Symantec Company, which makes many kinds of security( 安全 )software for home and business computers, there’s a "huge difference between parents and their kids".Parents of children under the age of 18 were asked to estimate(估计)how much time their kids spent online each week. The parents said about three hours a week on average( 平均 ).The kids－ages 8 to 17－who took the survey said they were spending an average of seven hours online each week. “I really think that’s because of the time they spend on their mobile phones and computers, when their parents don’t even know they’re online,” says Symantec’s Bill Rosenkrantz. “Remember, cellphones, PDAs and video game machines all make it possible to surf the Internet.
