They painted span>objects by 15 them into small pieces and then viewed and painted them from several angles at once. 16 used brown colors for the paintings.
The Cubism Movement started with Picasso and Braque in Montmartre, Paris, and 17 rapidly among the artists. It began to develop into a second stage in which artists added 18 objects to the painting in various materials, such as cloth or newspapers. In 19 1950s Picasso’s works went through more changes when he started to look at the grand masters of art, like Velasquez.
In his 80’s and 90’s, he began to paint a mixture of many styles that he kept changing. Only after his death 20 fully appreciate his great achievements and in 1999 one of his paintings sold for US $51 million.

【题目】
Doctors are known to be terrible pilots. They don’t listen because they already know it all. I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather, I learned about crew resource management(机组资源管理),or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.
I first read about CRM in 1980.Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear(起落架)down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said,“We need to put the landing gear down now!”That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.
CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again. So when I’m in the operating room, I ask for ides and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from“landing gear up”.
【1】 What does the author say about doctors in general?
A. They like flying by themselves.
B. They are unwilling to take advice.
C. They pretend to be good pilots.
D. They are quick learners of CRM.
【2】The author deepened his understanding of the power of CRM when .
A. he saved the plane by speaking up
B. he was in charge of a flying task
C. his boss landed the plane too late
D. his boss operated on a patient
【3】In the last paragraph“landing gear up”probably means .
A. following flying requirements
B. overreacting to different opinions
C. listening to what fellow doctors say
D. making a mistake that may cost lives
【4】 Which of the following can be the best title for the text?
A. CRM:A New Way to Make Flying Safe
B. Flying Makes Me a Better Doctor
C. The Making of a Good Pilot
D. A Pilot-Turned Doctor

【题目】
A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
【1】 The difficulty the team of engineers met with while making the robotic fly was that __________.
A. they had no model in their mind
B. they did not have sufficient time
C. they had no ready-made components
D. they could not assemble the components
【2】 Which of the following can be learned from the passage?
A. The robotic flyer is designed to learn about insects.
B. Animals are not allowed in biological experiments.
C. There used to be few ways to study how insects fly.
D. Wood’s design can replace animals in some experiments.
【3】Which of the following might be the best title of the passage?
A. Father of Robotic Fly/span>
B. Inspiration from Engineering Science
C. Robotic Fly Imitates Real Life Insect
D. Harvard Breaks Through in Insect Study

【题目】B
The rise in smartphones (智能手机) among young people may be having a direct effect on how successful they become as adults.
Research from the University of Nebraska Lincoln has discovered university students check their phones 11 times per lesson on average, and more than 80 percent believe this tech addiction is interfering with their learning.
A quarter of students across five American states also blamed poor grades in exams specifically on the fact that they used mobile devices when they should have been concentrating and revising and these grades could determine the jobs they end up going into.
Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom.
The students were from UNL, the University of Nebraska Lincoln at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi.
Around two thirds said they used phones, tablets and laptops for ＂non-classroom purposes＂ up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times.
Among the top reasons why 55 percent of students checked their devices so regularly were staying connected and fighting boredom. Less than half said the devices were used for classwork.
Texting was the most popular distraction (娱乐) technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and 8 percent admitted playing games when they should have been studying.
Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a ＂very big＂ distraction.
＂I don’t think students necessarily think it’s a big problem,＂ said McCoy. ＂They think it’s part of their lives.＂
【1】The majority of the students think that using smartphones __________.
A. helps to improve their grades
B. contributes to their poor grades
C. has a bad effect on their study
D. determines their jobs in the future
【2】 How many students surveyed used digital devices for ＂non-classroom purposes＂ about 30 times during a day?
A. About 518. B. About 116.
C. About 427. D. Less than 388.
【3】 Which of the following is TRUE?
A. Barney McCoy surveyed 777 students at the university he works in.
B. A minority of the students said they used digital devices for classwork.
C. Around two thirds admitted they used digital devices because lessons were boring.
D. Barney McCoy doesn’t think students’ using digital devices is a big problem.
【4】The text is most likely to be found in a section about __________.
A. successful people B. political systems
C. science and technology D. historical events
