My hobby is rock climbing. I’ve been doing them for two years. In the beginning, I wasn’t very good, so I’ve gotten much better. I started rock climbing in junior high school. On first day, I felt high nervous, so I only climbed low rocks. It was hard, but very interested. So I kept on work, and now I could climb very fast. I like rock climbing because of it helps me stay in shape. It’s also a good way to make friend. I’ve met a lot of people. We climb, but we also hang out and spend time doing another things now.

A new report found 46 percent of meals are eaten alone in America. More than half (53%) have breakfast alone and nearly half (46%) have lunch by themselves. Only at dinnertime 2. we eating together, 74%, according to statistics from the report.

"I prefer to go out and be out. Alone, but together, you know?” Bechtel said, 3. (look) up from her book. Bechtel, who works in downtown West Palm Beach, has lunch with coworkers sometimes, but like many of us, too often 4. (work) through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on 5. shoulder. She returns to work feeling energized. "Today, I just wanted some time to myself,” she said.

    The snow was falling and the roads had become dangerous. The schools were dismissed early, but much to my surprise, my ____ wasn’t canceled. So I went, feeling especially heroic. As far as I could see, I was risking my life to keep my ____. Snow or no snow, I would be on time for my scheduled donation at the local ____ center.

When I got there, I discovered I wasn’t _____. Four more “hero-types” were already lying back in donor chairs with lines ____ to their veins, and machines quietly pumping away to ______ their lifesaving gifts.

Seeing my fellow donors honoring their own commitments, I realized why I was there. I lay back in my donor chair, ready to make a difference in the life of someone I would never _____.

To be honest, I’d never really thought about why I donate. I just do it. But a few months ago, during one of my ____ donations I learned that my blood was specifically for a cancer patient and for a newborn baby—both patients needed what I would give in order to live. I’ve viewed my visits to the blood center _____ ever since.

My wife Karen is a _____, too. And more importantly, she has been on the bone marrow (骨髄) list for fifteen years, ever since she signed up to provide bone marrow to a kindergartner with leukemia (白血病). That little girl died before Karen’s bone marrow could help her, ____ Karen was called again recently. Her test results were still on file, and it turned out she was a potential ____ for someone else. The caller asked Karen if she would still be willing to become a bone marrow donor. “Yes,” she said and then immediately began answering questions on the pages of paperwork for further testing. It was a race ____ time.

I wish I could say that this ____ was won. It wasn’t. The caller later thanked Karen for her participation and asked a few more questions—including whether or not she’d ____ on the donor list. “Of course,” Karen answered.

Last week Karen gave blood and next week I’ll make my usual donation. I’ll ____ an afternoon from my schedule and make an appointment. I don’t know whose life my donation may ____.

    News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.

Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax — and her reactions change as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?

To find the answer, we have to analyze the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the AI news anchor reads, the micro- electric motors behind her face move to make her expressions seem more human.

Yet we need a thorough knowledge of deep learning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text for the AI to learn and read. The process for imitating facial movements is similar. The developer has to analyze the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to learn, and imitate the movements of facial muscles via programs

Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third — the technology to match the pronunciations with facial movements so that Xin’s expressions vary according to the content of the news report. In fact, Xin’s expressions don’t always change according to the content. As a result, her expressions look anything but human. Actually, AI is still no match for human qualities.

1.What does the underlined word “reluctant” in the first paragraph mean?

A.Delighted B.Unwilling

C.Confused D.Optimistic

2.What can we infer about previous news robots?

A.They read news without expressions. B.They looked like a human being.

C.They could interview sports stars. D.They could interact with audience.

3.From the last paragraph, we can draw a conclusion that     .

A.human news anchors should learn from AI anchors to save their jobs

B.Al anchors perform much better than human news anchors at present

C.Al news anchors won’t replace human news anchors in the near future

D.Xin Xiaomeng’s expressions vary so naturally that they are true to life

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index. Then he called the person who claimed to be the bike's owner and arranged to meet him-- supposedly to complete the sale. When the two men met, Bike Batman told the thief, "You've got two options. You can wait until a police officer gets here, or you can just get out of here." You can imagine what the thief did.

After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

His nickname came from a discussion with a police officer who suggested he be called "Robin Hood". Since he wasn't exactly stealing from the rich and giving to the poor, "Batman" seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.

1.When Bike Batman discovers a questionable bike, he will first ________.

A.contact the owner of the stolen bike B.look up the bike's information

C.call the police department D.arrange to meet the thief

2.Bike Batman helps find the lost bikes to ________.

A.become famous B.help poor people

C.punish bike thieves D.build a friendly city

3.From the passage, we can learn that ________.

A.Bike Batman felt relieved to see the thieves arrested

B.Bike Batman began his good deeds by accident

C.the police failed to perform their duties

D.the thieves refused to return the bikes
