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.

Now Glen doesn’t like to think what might have happened had he and his best friends, Ray Wightman and Chris Johnson, picked their usual path along a rocky outcrop－the faster route to Johnson’s home on Triangle Mountain. They were heading there after school that day－April 14, 1999－to play street hockey in Johnson’s driveway. There were other lucky twists, too: not stopping at the shops to get a cola, as they usually did; hearing the strange cry.

It was 3:30 pm. The three teens were laughing and talking when suddenly they heard a strange cry coming from the ditch(沟渠) across the road. Crossing to take a look, they found an Adidas gym bag sitting deep in the icy water. They climbed down the steep bank and pulled the bag from the water, expecting to find abandoned cats or dogs inside. Instead, the boys found a trembling newborn girl. Wrapped in an old blanket, wearing a thin nightshirt, she was almost blue, her lips shaking from the cold and her crying.

The boys couldn’t have been more astonished. They knew this one needed to get warm and dry, although they didn’t know much about babies. Ray dug through his gym bag and wrapped her in a T-shirt. “We didn’t know what to do,” said Glen. “I didn’t think any of us had really held a baby before.” So the three stood beside the ditch, dumbfounded, taking turns to hold the baby to their chests to keep her warm.

“We knew it was no use walking up to Ray’s house, because his mum was working and no one would be home. We figured we’d have a better chance just staying by the road and flagging down someone.” So they stood there and waited.

A car drove by and the boys caught the driver’s attention, telling her that they had found a baby. The woman then drove off to get help. When the police and ambulance came 20 minutes later, the teens were told the baby was probably two or three hours old and had perhaps been in the ditch for an hour or more. They were also told that they had saved her life and that given 10-20 minutes more in the cold water, she probably would be drowned.

1.On April 14, 1999, Glen and his best friends ________.

3.Why did the teens know it was no use walking up to Ray’s house?

A. Because it was too far away from Ray’s house.

B. Because his mum was working and no one would be home.

C. Because Ray’s parents had gone away on holiday elsewhere

D. Because the baby was in bad condition- and time was limited.

4.What can be the theme of the Text?

Having your nose in a book might seem a little anti-social at times—but reading could actually make you a kinder, more considerate person, a study has found. Readers were more likely to act in a socially acceptable manner, while those who preferred watching television came across as less friendly and less understanding of others’ views, researchers said.

123 participants in the study were quizzed on their preferences for books, TV and plays at Kingston University, London. They were then tested on how much they considered people’s feelings and whether they acted to help others. Researchers told the British Psychological Society conference in Brighton yesterday that fiction fans showed more positive social behavior.

Readers of drama and romance novels were also empathetic, while lovers of experimental books showed the ability to see things from different directions. Comedy fans scored the highest for relating to others. The study suggested reading allows people to see different points of view enabling them to understand others better.

The researchers added, “Exposure to fiction relates to a range of empathetic abilities. Engaging with fictional prose and comedy in particular could be key to improving people’s empathetic abilities.”

However, the authors warned the study did not prove cause-and-effect. So it could be that reading causes positive behavior, or it could be that thoughtful, well-mannered people are more likely to prefer reading. So it is a good idea to pick up a book to begin your travel with the author. Each author will show how they would react to certain situations through their characters. Everyone can view the same situation differently, and from 1,001 different angles. The more you read, the much better you can understand other peoples’ opinions.

1.Why did the writer mention the result of watching television?

A.The writer is a anti-social reporter. B.The writer shows benefits of reading.

C.The writer is a considerate person. D.The writer becomes socially acceptable.

2.What were the participants tested on?

A.The skills of communicating. B.The time of reading books.

C.The places of getting new books. D.The ways of expressing feelings.

3.Who can observe differently?

A.Readers of drama. B.Writers of romance novels.

C.Readers of comedy. D.Readers of experiments.

高二英语单词拼写中等难度题查看答案及解析

I know many people who spend time thinking about all the might-have-beens, what-ifs and opportunities they’ve missed. They spend their lives constantly feeling like they’ve missed out on something big. Their boats have sailed. They’ve missed their one and only opportunity to be rich, famous and do something really amazing.

I know someone who used to enter the same numbers in the lottery every week. One week, she was too busy to get the ticket before the agency closed. And her numbers came up. There were no winners that week and the jackpot money rolled over to the following week: 10 million pounds. She’s never forgiven herself. Since then, she’s lived her life feeling like she’s missed her boat, the only opportunity she’ll ever have to be happy.

I suspect most of us would be pretty upset if that happened to us. Now, the question is, would we allow it to rule the rest of our lives? Or should we consider the possibility that it happened for a reason?

Now, I’ll admit that I’d have a very hard time saying anything along those lines for quite a while if something like that happened to me. But, if I knew that I was putting every effort into being wealthy or happy, then I would also know that just because something didn’t happen the way it ought to happen, everything would still be alright. I will be able to relax and let it go.

Nothing ever happens to me, but everything always happens for me. So long as I’m keeping my eye on my goals, everything that happens is the Universe moving me towards my goals. It’s definitely easier said than done, particularly at first. But it is doable. It’s simply a choice.

You haven’t missed your boat. Your boat is still there. Don’t waste your life crying over someone else’s boat. Step onto your own.

1.When her lottery numbers came up, she wasn’t the winner because _____________.

A.she couldn’t forgive herself B.she was too busy to buy the ticket

C.she forgot the correct numbers D.she has missed her boat

2.What does the underlined sentence in Paragraph 5 suggest?

A.The world can’t change me.

B.I can change the world by working hard.

C.I have never missed any good opportunity.

D.Whatever happens to me is beneficial to me.

3.What’s the best title of the passage?

A.You Can’t Miss Your Boat.

B.You Shouldn’t Often Change Your Goals.

C.You Forgive Yourself as soon as Possible.

D.You Can’t Step onto the Boat that Has Sailed.
