二.阅读理解

    Many leading AI researchers think that in a matter of decades, artificial intelligence will be able to do not merely some of our jobs, but all of our jobs, forever transforming life on the earth.

    The reason why many people reject this as science fiction is that we've traditionally thought of intelligence as something mysterious that can only exist in biological organisms, especially humans. But such an idea is unscientific.

    From my point of view as a physicist and AI researcher, intelligence is simply a certain kind of information-processing performed by elementary particles (基本粒子) moving around, and there is no law of physics that says one can't build machines more intelligent than us in all ways. This suggests that we've only seen the tip of the intelligence iceberg and that there is an amazing potential to unlock the full intelligence that is potential in nature and use it to help humanity.

    If we get it right, the upside is huge. Since everything we love about civilization is the product of intelligence, amplifying (扩大) our own intelligence with AI has the potential to solve tomorrow's toughest problems. For example, why risk our loved ones dying in traffic accidents that self-driving cars could prevent or dying of cancers that AI might help us find cures for? Why not increase productivity through automation and use AI to accelerate our research and development of affordable sustainable (可持续的) energy?

    I'm optimistic that we can develop rapidly with advanced AI as long as we win the race between the growing power of our technology and the knowledge with which we manage it. But this requires giving up our outdated concept of learning from mistakes. That helped us win the race with less powerful technology. We messed up with fire and then invented fire extinguishers (灭火器), and we messed up with cars and then invented seat belts. However, it's an awful idea for more powerful technologies, such as nuclear weapons or super intelligent AI—where even a single mistake is unacceptable and we need to get things right the first time.

(1)How do many people feel about leading AI researchers' predictions?

A.Worried. B. Curious. C. Doubtful. D.Disappointed.

(2)What does the author think of intelligence?

A.We know little about it.

B.It belongs to human beings.

C.It is too difficult to understand.

D.We have a good command of it.

(3)What does the underlined word "upside" in Paragraph 4 probably mean?

A. Cost. B. Potential. C. Quantity. D. Advantage.

(4)What's important for us in the race between people and technology?

A.Learning from failure.

B.Increasing our intelligence.

C.Avoiding making mistakes.

D.Making accurate predictions.

三.七选五  

  "OK, class. Count off by fives." ①_________ Sometimes, breaking into small groups lasts as long as the class does. Other times, it signals the start of a "group project" — which means you'll be working with a few classmates for a day, several days, or longer on an assignment.

    Ever wondered why this type of project is so popular in school? Or what you can do to make sure your group project is fair, fun, and successful? You want a good grade, right?

    ②_________ Most things are done with the help or ideas of other people. Group projects are great practice for high school, college, and real life, when you will probably have a job that requires working with others. Right now, group projects can be fun and they often allow you to do a bigger, more interesting project than you could alone. ③_________

    ④_________ For example: working on a deadline, staying organized, or being patient. And if you're a little nervous talking in front of a group, a joint project can help you become more comfortable with it. Maybe your group will pick you to tell the whole class about your project. ⑤_________

A. Few of us act alone in the real world.

B. If so, you'll know your whole group is supporting you!

C. With group work, you can actually learn more in less time.

D. You are going to have a break and get relaxed for a while.

E. Group projects are also a great way to practice your skills.

F. When hearing the instruction, you know what's coming next.

G. Learning to be independent is very important for students in their future life.

答案：(1)-(4)CADC

解析：(1)推理判断题.根据第二段中的 "many people reject this as science fiction" 可以推知,很多人不相信 AI 研究者的预言,认为那更像是科幻小说.故选C.

(2)细节理解题.根据第三段中的 "we've only seen the tip of the intelligence iceberg." 可知,作者认为,人类对智能的认识还只是冰山一角.故选A.

(3)词义猜测题.第四段主要论述了恰当利用人工智能的好处第一句是本段的主句. upside 意为 "好的一面,优势", 相当于 advantage. 故选D.

三.

答案：FACEB
解析：①前面的"'OK, class. Count off by fives.'"是老师发出的指令,F项中的"When hearing the instruction..."可承接上文内容。
