It’s always nice to have a little help around the house. But what if you could employ the assistance of one of the greatest minds of the 20th century？

That’s the idea behind a new robot modeled after Albert Einstein. Called Professor Einstein and standing at just over a foot tall, this personal assistant can tell you the weather and keep track of your schedule like any other robots. With built-in Wi-Fi, Einstein robot has access to brain ceasing games, and can answer math problems and science questions. With natural language speech processing, you can actually interact with Professor Einstein. And because the robot is connected to the Internet, it is constantly updated with new information.

To help get the perfect replica（复制品）of Einstein, the Hong Kong-based tech company Hanson Robotics turned to the Hebrew University of Jerusalem, the home of the Albert Einstein archives（档案）. “We worked very closely with them to bring the product co marker,” the company’s Dr. Jeanne Lim said.

Einstein robot was introduced to the public at the Consumer Electronics Show in Las Vegas and was quickly hailed by those who saw it. “He became one of the breakout stars of the convention,” wrote Melia Robinson on Business Insider. “Crowds flooded into the company to have a look at the little guy.”

“Technology is often now very cold and socially isolating（孤立的）,” explained David Hanson, the co-founder of the company behind the new robot, “By bringing an lively character into our physical world, we’re humanizing（使人性化）the technology instead of dehumanizing the humans.”

As for Hanson Robotics, the company has been building human-size robots for over a decade. But this marks the company’s first commercially available product. “Professor Einstein is just the start,” said Hanson. “We’re witnessing the arrival of conversational robots that can walk in our world. It’s a golden age of invention.”

1.What can Einstein robot do？

A.Teach you to learn any new language.

B.Have a regular conversation with you.

C.Design a number of science questions.

D.Keep track of other robots constantly.

2.Which of the following best explains “hailed” underlined in paragraph 4？

A.Broken. B.Improved.

C.ignored. D.Praised.

3.What can be inferred from David Hanson’s words？

A.He expects humans to be less isolated from robots.

B.He dreams of humanizing humans through invention.

C.He worries about a golden age for conversational robots.

D.He stays hopeful about the future of robot invention.

4.What can be a suitable title for the text?

A.A New Robot Makes Humans Much Happier

B.The Golden Age of Invention Is Approaching

C.Albert Einstein Changes into an Assistant

D.Albert Einstein Helps to Humanize Robots

How many times have you got upset because someone wasn't doing his job，because your child isn't behaving？How many times have you been irritated (恼怒的) when you've planned something carefully and things didn't go as you'd hoped?

This kind of anger and irritation happens to all of us—it’s part of the human experiences.

One thing that irritates me is when people talk during a movie，or cut me off in traffic. Actually, I have a lot of these little annoyances—don't we all？And it isn’t always easy to find peace when you’ve become upset or irritated.

Let me tell you a little secret to finding peace of mind: see the glass as already broken .

See, the cause of our stress, anger and irritation is that things don't go the way we like, the way we expect them to. Think of how many times this has been true for you. And so the solution is simple：expect things to go wrong, expect things to be different than we hoped or planned，expect the unexpected to happen. And accept it.

One quick example: on our recent trip to Japan, I told my kids to expect things to go wrong—they always do on a trip. I told them, “See it as part of the adventure.”

And this worked like a charm. When we inevitably(不可避免地) took the wrong train on a foreign­language subway system, or when it rained on the day we went to Disney Sea, or when we took three trains and walked 10 blocks only to find the National Children's Castle closed on Mondays...they said, “It's part of the adventure！” And it was all OK—we didn't get too bothered.

So when the nice glass you bought inevitably falls and breaks some day, you might get upset. But things will be different, if you see the glass as already broken, from the day you get it. You know it'll break some day, so from the beginning, see it as already broken. Be a time­traveler, or someone with time­traveling vision, and see the future of this glass, from this moment until it inevitably breaks. And when it breaks, you won't be upset or sad—because it was already broken, from the day you got it. And you’ll realize that every moment you have with it is precious.

1.The author’s children could enjoy their trip to Japan because________.

A. everything went smoothly

B. they had a lot of adventures

C. they had expected things to go wrong

D. they could soon get used to the customs there

2.The author would probably agree that________.

A. we should control our anger and irritation

B. we must get well prepared for the future

C. optimism can help us overcome our anger and irritation

D. anger and irritation is a natural part of our life

3.The purpose of the author is to________.

A. tell us his own experience in life

B. advise us how to find peace of mind

C. tell us a happy trip he took with his children

D. ask us to see things from both sides

4.By the underlined part (in Para.3), the author tells us to________.

A. get ready for the worst result of things

B. enjoy the process of things

C. expect little from life

D. find the relationship between cause and effect

5.We can learn from the passage that the author________.

A. often gets angry in his life

B. can adjust his state of mind accordingly

C. always expects others to act in his way

D. always suffers from his anger and irritation

Entrepreneur and CEO of Tesla and Space X, Elon Musk may have a little more time on his hands, as he’s leaving his position on the board of the Open AI, according to a blog post.

The departure is likely the result of Tesla’s moving into the field of Artificial Intelligence(AI)，which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Elon.”

Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv. Org, detailing the possible secure threats that come with “malicious” AI. In fact, Musk has heard of the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people. ”

Musk’s departure from the Open AI board could mean big things for Tesla. As Elon Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own Al projects than we thought.” He added, “Those who have had their ears to any rumors that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open Al development as a sign that the company is inching closer to that unapproachable goal. ”No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.

1.Why does Elon Musk leave his position?

A. To create safer AI.

B. To build the powerful Internet.

C. To develop social communication.

D. To avoid a possible conflict with Tesla.

2.What is the Elon Musk’s attitude towards the AI?

A. Suspicious　　 B. Negative.

C. Sympathetic.　　 D. Supportive.

3.What can we infer from Elon Goodbye’s comments?

A. Level 5 autonomy is impossible.

B. The rumors about Tesla is meaningless.

C. He has no confidence in Open AI.

D. Level 5 autonomy could set human drivers free.

4.What’s the best title for the text?

A. Elon Musk is planning to compete with AI.

B. Elon Musk is stepping down from AI safety group he co-founded.

C. Elon Musk: AI is humanity’s biggest existential threat.

D. Elon Musk: Open AI will take new measures to cooperate with Tesla.
