When Barzilay had a routine breast X-ray in her early 40s, the image showed a complex group of white spots in her breast tissue. The marks could be normal, or they could be cancerous-even the best doctors often struggle to tell the difference. Over the next two years Barzilay underwent a second X-ray, a MRI and a biopsy and she was finally diagnosed(诊断) with breast cancer in 2014.
Barzilay was treated and made a good recovery. But she remained terrified that the uncertainties of reading an X-ray could delay treatment so she made a career-changing decision.
A computer scientist at Massachusetts Institute of Technology, Barzilay had never studied health before. Her research used machine-learning techniques for natural language processing. But she had been looking for a new line of research and decided to team up with radiologists (放射科医生) to develop machine-learning algorithms (算法) that use computers' superior visual analysis to spot patterns in X-rays that the human eye might miss.
Over the next four years the team taught a computer program to analyze X-rays from about 32,000 women and told it which women had been diagnosed with cancer within five years of the scan. They then tested the computer's matching abilities in 3,800 more patients. Their resulting algorithm, published last May in Radiology, was significantly more accurate at predicting cancer than practices generally used in clinics. When Barzilay's team ran the program on her own X-ray from 2012-one her doctor had cleared-the algorithm correctly predicted she was at a higher risk of developing breast cancer within five years than 98 percent of patients.
AI applications are entering clinics at a rapid rate, and physicians have met the technology with equal parts excitement about its potential to reduce their workload and fear about losing their jobs to machines. Algorithms also raise questions about how to regulate a machine that is constantly learning and changing and who is to blame if an algorithm gets a diagnosis wrong. Still, many physicians are excited about the promise of AI programs.
1.What advantage do Barzilay's algorithms take of computers to predict cancer?
A.Superior visual analysis.
B.Timely risk warning settings.
C.Natural-language processing techniques.
D.Large storage of radiological knowledge.
2.What does the underlined word "it" in Paragraph 4 refer to?
A.Cancer. B.Research.
C.The team. D.The program.
3.How do physicians react to AI applications in clinics?
A.They doubt the accuracy of the applications.
B.They have mixed feelings about the applications.
C.They promise to make the best of the applications.
D.They expect to rapidly popularize the applications.
4.It can be inferred from the text that
A.Barzilay suffered from breast cancer for two years in her forties
B.at first Barzilay didn't think X-ray was a reliable way of checking cancer
C.with Barzilay's algorithms her cancer could have been diagnosed earlier
D.Barzilay failed to turn to the best doctors to have her breast checked

When I had breast cancer I had to have chemotherapy (化疗). The hardest part of that entire experience was losing my hair. It was like having a tattoo(纹身) across my forehead that said “chemotherapy patient.” I am a very active and athletic person, so to have people looking at me with pity as if I was an invalid was very hard to take. Of course they never said anything, but if I got in an elevator. Everyone looked away because they didn’t know what to say. But I didn’t blame them.
The best compliment I ever received was when I was at work one day, wearing my scarf over my bald head, and a UPS guy came in to deliver a package. He looked me right in the eye and said, “So, are you on chemotherapy?” I said, “Yes, thank you for asking. You are the first person to actually acknowledge that fact.” It felt so good to be talked to like a “real” person, without any pity, just the facts. I asked him what made him decide to say something, and he told me that a woman he worked with had just gone through the same thing several months before.
I had some joke business cards that said my job title was “Supreme Commander of the Universe”, so whenever this same UPS guy came to deliver a package, he would also say, “Hey, Supreme Commander, how is it going?” Then my company moved to a new location, and since that time I hadn’t seen the UPS guy-Bryan- in probably two years.
I went to answer my door at home one day, and there was Bryan with a package. Small world. “Hey, Supreme Commander, long time no see!” he said. He sees so many people all day long, every day, delivering packages but he remembered me after two years. What a great compliment! Of course, I remembered him, too, because he was the only person who could see me during that time when I was “the invisible woman.”
1.Why did the author say “It felt so good to be talked to like “real” person”?
A. Because her friends didn’t realize the fact that she got sick before.
B. Because her friends didn’t want to talk with her since she had cancer.
C. Because her friends treated her as a patient.
D. Because her friends were afraid of infection.
2.What can be inferred from the third paragraph?
A. It was the author’s cancer that helped her to be remembered by a stranger.
B. The UPS guy had become a good friend of the author’s.
C. The guy was very polite.
D. The author didn’t want to be remembered for her cancer.
3.What was the author’s attitude towards her cancer?
A. Surprised. B. Regretful.
C. Positive. D. Depressed.
4. What is the main idea of the passage?
A. The author experienced something miserable after she had cancer.
B. The author got a great compliment that a stranger remembered for her cancer.
C. the author became strong and positive after she was ill.
D. The author recognized that she was not a normal person any longer.

Agnes de Mille was a dancer and a choreographer (编舞). Early in her career, de Mille had created the choreography for a ballet called Three Virgins and a Devil. She thought it was good work, but nobody made much of it.
A few years later, de Mille choreographed a ballet named Rodeo. Again, she thought her work was solid, but it resulted in little commercial fame.
Then, in 1943, de Mille choreographed Oklahoma!, a musical show that enjoyed nearly instant success. In the coming years, Oklahoma! would run for an incredible 2,212 performances, both around the nation and abroad. In 1955, the film version won an Academy Award.
But the success of Oklahoma! didn’t bring her much happiness. She thought that her work on Oklahoma! was only average compared to some of her other creations. She later said, “After the opening of Oklahoma!, I suddenly had unexpected success for a work I thought was only fairly good, after years of neglect for work I thought was fine. I began to think that perhaps my entire scale of values was untrustworthy. I talked to Martha.”
Martha was Martha Graham, perhaps the most influential dance choreographer of the 20th century. (Although not as well-known by the general public, Graham has been compared to other creative geniuses like Picasso or Frank Lloyd Wright.)
During their conversation, de Mille told Martha Graham about her frustration. “I confessed that I had a burning desire to be excellent, but no faith that I could be.”
Graham responded by saying:
“There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open.”
1.What can be learned about de Mille’s ballet named Rodeo?
A.It earned her a large fortune. B.It made her rise to fame overnight.
C.It didn’t enjoy much success. D.It laid a solid foundation for her career.
2.How did de Mille feel about the great success of the musical Oklahoma!?
A.Relieved. B.Ashamed. C.Confused. D.Proud.
3.Picasso and Frank Lloyd Wright were mentioned in the passage to suggest that Martha Graham ______.
A.was outstanding in visual arts and architecture
B.enjoyed the same popularity as them
C.had been influenced greatly by them
D.was the most influential artist in her field
4.Which of the following statements best represents Graham’s words in this passage?
A.Comparing with others prevents you from maintaining uniqueness.
B.You should always keep yourself open to the urges that motivate you.
C.Your action reveals the inner landscape, which is the soul of music.
D.Choosing to be positive is going to determine how you live your life.

Kemira Boyd had just jumped in the shower when she heard her stepmother, Tammy Boyd, banging on the door. Kemira's 12-day-old daughter was choking. Having fed baby Ryleigh just 30 minutes earlier, the 24-year-old new mother burst out of the bathroom and began patting her daughter on the back. Ryleigh was usually quick to cry. Now she didn't make a sound. “I'd been told to raise their arms when babies are choking, so I tried that, but she still was hesitating to breathe,” Kemira told Today. She knew Ryleigh needed to get to the hospital fast.
The trio had barely made it out of their Summerville, South Carolina, neighborhood when the flashing lights of a police patrol car appeared behind them. Deputy Will Kimbro figured that the speeding driver was either too distracted to notice him or simply unconcerned. (1) Kimbro soon found cut it was a frightening combination of the two.
Once she had pulled over to the roadside, a crazy Tammy jumped out of the car, exclaiming that her granddaughter had stopped breathing. Desperate for help, Kemira handed the baby to Kimbro. He put a hand on her little chest. Ryleigh's heart was barely beating.
Kimbro radioed for an ambulance-it was seven minutes out, and the hospital was even further away. That was seven minutes Ryleigh didn't have, her lips already a bad shade of blue. ② He is a school resource officer who usually spends his days patrolling the halls of the middle school ten miles away. But he travels farther away when school is out in the summer. Even luckier: he had recently completed a CPR class and knew exactly how to treat a baby. “Although I was shocked, my training kicked in, and I went to work to keep that baby alive,” says Kimbro.
The deputy gave Ryleigh to Kemira to hold, his hands busy as he checked for a pulse. Then he began tapping and pressing Ryleigh's chest, hoping to massage her heart back into action. Thanks to the CPR class, Kimbro knew the choking baby didn't have a chance if there was a blockage, and he used one finger to clear her airway. That was the magic touch; 20 seconds later, Ryleigh began to fuss. Then came a weak crying sound. “If she is crying like that, she is breathing, said kimbro, the relief apparent in his trembling voice.” As long as she is crying, she is breathing.
But they still had five more minutes until EMT would arrive, and Kimbro worried that Ryleigh would be unable to breathe again. He continued with delicate chest compressions and periodically clearing her airway. “The whole time I was thinking ' Do not let this baby die in front of her mother and grandmother',” he later told Inside Edition.
③ In the body cam footage, Kimbro can be heard reassuring Kemira, the approaching sirens wailing in the background: “I didn't feel a heartbeat earlier, so I started massaging her heart, and now I feel it. It's real strong now.”
After transferring Ryleigh to an EMT, Kimbro peeked into the windows of the ambulance until it pulled away. ④ At the hospital, Ryleigh recovered quickly, and she was back to her usual active self in no time-thanks to a determined school police officer who was in the right place at the right time. Said Kimbro to the Washington Post, “That baby was living no matter what I had to do.”
1.Why did Kemira decide to send Ryleigh to hospital?
A.Ryleigh remained asleep. B.Ryleigh was quick to cry.

D.A CPR lesson is a must for police officers in Summerville, South Carolina.
3. “The fact that Kimbro was there was something of a miracle.” Which blank does this sentence best fit in?
A.① B.② C.③ D.④
4.How can Kimbro's life-saving process be described?
A.It was professional and delicate. B.It was vital for Kimbro's career.
C.It was tense and tiresome for Kimbro. D.It was awkward and shocking.

A.The baby would have survived even if he hadn’t done anything.
B.He patrolled away from the middle school in order to save the baby's life.
C.He considered it his responsibility to be in the right place at the right time.
