Each sentence can only be used once.Note that there are two sentences more than you need.Seeking feedback not always sufficient for stimulating creativity It is widely believed that seeking feedback from colleagues, managers, friends and family enhances employees' creativity. But is this always the case? No, a positive effect depends on the work environment. This is the conclusion of new joint research study led by UAA work and organizational psychologist Roy Sijbom.(67)________For example, managers are encouraged to engage customers in order to confirm whether their business model is workable and scholars attend conferences to obtain feedback on their research results. A definite assumption is that individuals who have obtained feedback will also actually (be able to) use it.“The idea i s simple: seeking feedback from different sources -- also known as feedback source variety -- benefits one's creativity since it leads to a greater diversity of viewpoints”, says Sijbom. “And the more diverse the viewpoints, the more it benefits one's crea tivity because by combining all the different viewpoints new perspectives will emerge that in turn will result in more creativity.(68)________ ”The researchers examined how specific characteristics of the immediate work environment influence the relationship between feedback source variety and creative performance.(69)________ One is the recognized rate of change of performance standards. The other is the extent to which employees feel they have sufficient time to develop creative ideas at work (experien ced creative time pressure). “We discovered a growing relationship between the search for input from a variety of feedback sources and creativity, but only when performance standardswithin an organization are changing and when a relatively low creative time pressure is experienced”, says Sijbom.Sijbom offers several recommendations: “(70)________In a more concrete sense, organizations can, for example, consider using feedback workshops in which employees are encouraged to reflect on diverse feedback and equipped with techniques and strategies on how to absorb feedback in their daily work. In addition, managers should not only stimulate their employees to actively cultivate relationships with potential feedback sources within and outside the organization, but also provide sufficient time to process the feedback obtained from these relationships.”67--70 CEAD【2018-崇明区-高三英语-二模】Section CDirections: Read the following passage.

Note that there are two more sentences than you need.Feel Y oung at Heart and Y ou’ll Enjoy a Longer LifeAge-liars and birthday-deniers... you’d best learn a thing or two from those who are young at heart. People who feel younger than their actual age may live longer than those who feel older than they truly are, a new study says.67_______ Results from the study, published in the Journal of the American Medical Association, suggest that people who feel a year or more older than they truly are could have around 41 percent greater risk for death.Researchers looked at nearly 6,500 older adults, with an average age of 65.8 for the study. Around70 percent of them felt younger than they were, about a quarter felt their precise age and just under 5 percent felt a year or more older than they were, when asked “How old do you feel you are?”Those who felt older than they were had a higher death rate after a follow-up period of 99 months. While just 14.3 and 18.5 percent of people who felt younger or felt their age, respectively, died during those 99 months, 24.6 percent of those who felt aged beyond their years had died.The authors say more research is needed on the topic, but suggest it could be that those who feel “young at heart” have healthier behaviors and a stronger will to live. “ 68______Individuals who feel older could be targeted with health messages promoting positive health behaviors and attitudes toward aging,” the authors write in the study.The good news is that you can change your feeling of how young you are. 69______One recent study found that helping participants have positive feelings toward age, by showing them positive word associations, helped older adults improve in physical tasks like balancing and getting up out of a chair, in as little as four weeks. Another study found that negative feeling of aging andpoor memory can make older adults feel up to five years older, regardless of their actual mental abilities.There you have it.70 BDEA【2018-奉贤区-二模】Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in theYou won’t have any excuse to skip class anymore. French startup OpenClassrooms is offering the first State-recognized bachelor degree in France that uses only MOOCs (massive open online courses). The startup partnered with IESA Multimédia to create this program.There are three learning paths in engineering, design and marketing. Students will have to complete all the courses and required projects in order to get their degree. 67______ IESA is already working on 40 different MOOCs for this program.On average, it will take a year of hard work in order to complete all the classes. As always, it’s hard to keep going when you sign up for a MOOC. 68_______This kind of degree has many key advantages. For IESA, it gives the school more students. IESA is a private school, and its end goal is to make as much money as possible. So with these new MOOC students, IESA will be able to get more money per teacher on average.69______The startup already offers a course for €20 per month, but you need to pay €300 per month for the Premium Plus offering to use the state-recognized program. It’s unclear ho w much OpenClassrooms will keep, but it should be more than €20 per month.For students, it’s a cheaper way to get a degree. Maybe you can’t afford to study for three years at IESA and pay €6,950 per year. 70______ Sure, it’s probably a less enjoyable experience than going to your school and spending time with other students and teachers, but it makes sense for some students.It’s an interesting new direction for OpenClassrooms, and I can’t wait to see whether other schools will start working with the startup to provide online courses. It will be interesting to see whether the first students are satisfied with this kind of degree as well.C D A F【2018-虹口区-二模】Directions: Read the passage carefully.

But you still have to wash those dishes and take care of those routine tasks at work or in school. So what can you do not to get lost in procrastination (拖延) ?I’ll share how I do it, how I get some motivation and find more pleasure in what may seem to be a boring task.Instead of focusing your mind on how boring a task may feel, focus your thoughts on why you are doing this and how good it will feel when you are done with it. If needed, sit down for a few minutes, close your eyes and see in your mind. Then go to work with that motivation and those positive feelings in your body.Do it attentively. 67______Focus 100% on just the work with all your senses—how it feels, looks and smells—as you are scrubbing it and nothing else. Don’t get lost in daydreams. If you are just there, I have found that even such a simple task becomes more enjoyable and something that can bring inner calm rather than distress.Make a deal with yourself and set a timer for 10 minutes. It is often easier to do tasks like these in small bursts. So make a deal with yourself to just spend 10 minutes on your reading or cleaning the house.68_____When the timer rings you can continue doing it if you feel like it (this often happens to me because getting started is the hard part) . Or you can stop and go do something more interesting instead.Create a pleasurable distraction. If possible, try to listen to the radio, your favorite songs, an audio book or watch a movie or TV episode while doing your boring task. 69_____I often listen to music or watch an episode of the Simpsons while doing the dishes or other routine work at home.70_____ Take a walk in the sun. Move on to a more fun or creative task at work or in school. Have a tasty treat. This habit can make it easier to get started and to keep going each day. Because you know that you can look forward to not just being done and the long-term payoff from that but also your immediate reward right after you are finished.E D F A【2018-黄浦区-二模】Section CDirections: Read the following passage.

A traditional car wash’s heavy brushes could jar the vehicle’s sensors, disturbing their standardization and accuracy. Even worse, sensors, which can cost over $100,000, could be broken. __68__ Dirt, dead bugs, bird droppings or water spots can impact the vehicle’s ability to drive safely.Avis, which has years of experience managing rental cars, has been tasked with cleaning and refueling the self-driving vans of Waymo, the self-driving arm of Google’s parent company. Avis chief innovation officer Arthur Orduña told CNN, “There a re special processes that definitely require a lot more care and focus, and you have to clean the vans quite often.”__69__ But other self-driving car companies such as Toyota, Aptiv, Drive, AI and Uber described to CNN that they use microfiber (微纤维) cloths along with rubbing alcohol, water or glass cleaner for manual cleanings.__70__ This should ease some need for manual cleaning. But because self-driving vehicles can have doze ns of sensors, Seeva CEO Diane Lansinger doesn’t imagine products like this will be able to clean every camera, radar or LIDAR, a laser sensor that most experts see as essential for self-driving vehicles.

Note that there are two more sentences than you need.The Minoans: A Forgotten PeopleThe first advanced culture in ancient Greece was the Minoan culture. For thousands of years, knowledge of these people survived only in Greek myths. In the late 19th century, archaeologists began to unearth ruins. This inspired Arthur Evans to begin digging on the island of Crete near mainland Greece. On a dig in Kbossos, Evans found an ancient palace. Experts think that it was the palace of King Minos, a central figure in many Greek myths.67_____With his team, he uncovered a vast structure, varied works of art, and many hieroglyphic records. These finds, together with later finds, comprise all that experts know about Minoan culture.From the evidence experts gathered, it is clear that the Minoans were ahead of their time. The palace at Knossos was five floors high with hundreds of rooms. Buildings throughout the ancient city had plumbing and flush toilets. Stone pavement lined the surfaces of the roads. In addition, the Minoans possessed a highly developed naval fleet for long-distance trade. 68_____ These records confirm the central role of commerce in culture. Expert analysis of the evidence also offers insight into some aspects of Minoan society.69_____Ruins and artwork suggest that people of all classes enjoyed a high degree of social and gender equality. Religious icons show that Minoans worshiped bulls, the natural world, and many female gods.An unusual feature of Minoans culture was the pursuit of leisure interests. Sport and visual arts were central to Minoan life. Boxing and bull jumping, a sport in which players jumped over live bulls, were popular. Although bull jumping may have served some ritual purpose, experts believe that it was done mostly for fun. Similarly, although some works of art showed political and religious themes, other works served only as pleasant décor (装饰品).70_____ The Minoans met their demise after a series of natural disasters. Experts believe that group from the Greek mainland capitalized on these events and looked over the island.67-70. DFBA【2018-金山区-二模】Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.No one enjoys the moment. You are stuck at the back of a queue and as those in other lines move ahead and get served, the time to decide arrives. ____67____This question has now been solved by researchers at Harvard Business School. According to what they have found in a new study, they suggestpeople think twice before switching queues.The research was led by Ryan Buell, an expert in service management. He looked intoconsumer queuing behavior after working with economists on what is known as “last-place aversion,” the discomfort people feel when they know they earn less than others or consider themselves at the bottom of the social pile for some other reason. As a result of this aversion to being the last, when a person finds himself at the end of a queue, he can make decisions that he will later regret.Buell began by observing people at a multi-checkout grocery store and then set up an online survey. People who took part in the survey were told it would take about five minutes. In reality, it took only one minute, but when participants logged in for the survey, they were forced to wait in a virtual queue displayed on the screen. They started at the back and could wait, switch to a second queue or choose to leave.____68____ On average, however, those who switched waited 10 percent longer than if they had stayed put. Those who switched twice ended up waiting 67 percent longer than if they had never moved.“When we join a queue, we tend to make the most rational choice we can, which means joining the shortest queue. ____69____ Unfortunately, we can often get it wrong,” said Buell.____70____ After that, the aversion fades. The researcher suggests people have a chat with the person in front so that they can pass the time more comfortably until someone else joins behind them. “Remember that the person in front of you was the last until you arrived, so someone will show up if you h ang around long enough,” Buell said.67-70: CBAE【2018-静安区-二模】Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.Most people don’t need science to appreciate the importance of a mother’s love. But to und erstand how early maltreatment can derail a child’s development requires careful study.In a famous research, Harry Harlow had demonstrated that proper psychological and physical development of infants requires nurturing and attention from a parent. ___67___ In that research, socially isolated monkey babies that were removed from their mothers were found to be clinging to a cloth-covered surrogate (替代的) mother for comfort.Such experimentations sound cruel. They, however, have been critical in helping change policies in human orphanages ( 孤儿院) in the U.S. For centuries some orphanages treated infants equally inhumanely. Despite early evidence that orphanage infants were far more likely to die than others, supporters argued that it didn’t matter whether children had “parents” specially devoted to them at the orphanage. ___68___ Orphans were supposed to be in positive mental and physical health until adoptive parents were found. Babies,they said, couldn’t remember anyway.The harrowing consequences of these theories were most vividly brought to light in Romania in the 1980s and ‘90s. A ban on abortion(流产) led to a surge in orphanage babies. Simply being fed and changed without individualized affection, some babies present serious problems. Many developed violent behaviors, repetitively rocking or banging their heads. Some were cold and withdrawn or indiscriminately affectionate. ___69___ Their head sizes were especially small. They even had problems with attention and comprehension. The longer these children were left alone, the more damage was seen.The lack of a secure attachment relationship in the early years has destructive consequences for both physical and mental health later in life, with long-lasting effects. The persistence of these effects emphasizes the need to intervene early in life. The Nobel-prize-winning economist James Heckman, has long argued that investing in early childhood education provides a greater return for society than virtually any other type of spending. It is obviously reflected in increased educational success and productivity,. The reduced crime, addiction, distress and disorder point to the same theory. Early life conditions critically affect adult life. ___70___ Remove it and theharm is great.67-70 EBFD【2018-闵行区-松江区-二模】Section CDirections: Read the following passage carefully.

Note that there are two more sentences than you need.Rhythm of LifeChoosing the right time to sleep, the correct moment to make decisions, the best hour to eat—and even go into hospital—could be your key to perfect health.Centuries after man discovered the rhythms of the planets and the cycles of crops, scientists have learned that we too live by precise rhythms that govern everything from our basic bodily functions to mental skills. Man is a prisoner of time.But it’s not just the experts who are switching on to the way our bodies w ork. 67Prince Charles consults a chart which tells him when he will be at his peak on a physical, emotional and intellectual level. Boxer Frank Bruno is another who charts his bio-rhythms to plan for big fights.68 Sleep, blood pressure, hormone levels and heartbeat all follow their own clocks, which may bear only slight relation to our man-made 24-hour cycle.Research shows that in laboratory experiments when social signals and, most importantly, light indicators such as dawn are taken away, people lose touch with the 24-hour clock and sleeping patterns change. Temperature and heartbeat cycles lengthen and settle into “days” lasting about 25 hours.In the real world, light and dark keep adjusting internal clock to the 24-hour day. But the best indicator of performance is body temperature. As it falls from a 10 p.m. high of 37.2°C to a pre-dawn low of 36.1°C, mental functions fall too. 69______The most famous example is the nuclear accident at Three Mile Island in the US. The three operators in the control room worked alternating weeks of day, evening and night shifts.70_____ Investigators believe this caused the workers to overlook a warning light and fail to close an open valve.Finding the secret of what makes us tick has long fascinated scientists and work done over the last decade has yielded important clues. The aim is to help us become more efficient. For example, the time we eat may be important if we want to maximize intellectual or sporting performance. There is already evidence suggesting that the time when medicine is given to patients affects how well it works.【2018-浦东区-二模】Section CDirections: Read the passage carefully.

But Why?In the 1970s, the original place to play a computer game was at an arcade. Here, you and your mates could try out the new big names in games such as Space Invaders and Pacman. _____67_____ And because of the technology involved, the gaming machines were too big to fit into your house.But in the 1980s and 90s, gaming arrived in our homes and people like me were addicted. The sound of beeping became a familiar sound emanating from bedrooms across the land! Names such as Tetris, Sonic and Street Fighter became popular language in the playground -- and now they are being talked about -- and played again. One of the reasons is the low cost. The BBC spoke to gamer, Gemma Wood, who says that: _____68_____ I understand that a lot of hard work has gone into the design etc., but how can anyone justify £50 to £60 for a game that you might not even enjoy?_____69_____ The graphics on old games may not compare with the detail and definition of modern games but they are fun and easy to use by children and adults alike. And of course, nostalgia plays its part. Some people want to relive their childhood while for others, it is a chance to show their children the computer games they grew up with.Technology journalist, KG Orphanides, says “it's important to recognize how well-designed many of those classic games are... the developers had so little space to work with -- your average Sega Mega Drive or SNES cartridge had a maximum capacity of just 4mb -- and limited graphics and sound capabilities.” This compares to an average capacity of 40G in today's games. _____70_____This craze for using retro hardware and grabbing an old joystick is certainly catching on. And to persuade those of us who are not sure about downgrading the gaming experience, manufacturers such as Nintendo, are bringing back some of their older consoles in new style casing.67-70B E A C【2018-普陀区-二模】Section C 8%Directions: Read the passage carefully.

To those who do not recognize their unique worth, imitation appears attractive; to those who know their strength, imitation is unacceptable.In the early stages of skill or character development, imitation is helpful. When I first learned to cook, I used recipes and turned out some tasty dishes. But soon I grew bored. ______67______Imitat ing role models is like using training wheels on a child’s bicycle; they help you get going, but once you find your own balance, you fly faster and farther without relying on them.______68______ If, as a child, you observed people whose lives were bad, you may have accepted their fear and pain as normal and gone on to follow what they did. If you do not make strong choices for yourself, you will get the results of the weak choices of others.In the field of entertainment, our culture glorifies celebrities. Those stars look great on screen. But when they step off screen, their personal lives may be disastrous. ______69______Blessed is the person willing to act on their sudden desire to create something unique. Think of the movies, books, teachers, and friends that have affected you most deeply. They touched you because their creations were motivated by inspiration, not desperation. The world is changed not by those who do what has been done before them, but by those who do what has been done inside them. ______70______ The problem a creator faces is not running out of material; it is what to do with the material knocking at the door of imagination.Study your role models, accept the gifts they have given, and leave behind what does not serve you.

During the speech, which lasted two and a half hours, Shan touched on topics including upgrading museum infrastructure(基础设施), restoring cultural sites, digitalizing online museums, setting up restoration hospitals, providing better visitor experiences and promoting the Palace Museum’s cultural items.“The abundant collection of cultural o bjects at the Palace Museum is the inspiration for the creative souvenirs and cultural items available,” Shan said. “ 68_____ ” Throughout 2017, the total sales of Palace Museum’s cultural items have been more than 1 billion yuan ($158million). Explaining the huge success of Palace Museum’s cultural souvenirs, Shan said: “The museum opened a shop on the e-commerce website Taobao in 2008, but sales remained neither high nor low for years, as more than 80 percent of the souvenirs sold in stores in the past were not related to our museum.” “Therefore, I wanted to change the situation. Now, souvenirs from the Palace Museum cover almost every aspect of life. After all, what matters to a museum is not how many visitors they have, but how close they are to people’s daily lives.”69______ Around 200 “doctors” are employed to analyze, examine, detect flaws or damage in ancient objects and restore them using more than 100 pieces of specialized equipment, including 3-D printers and scanners. The restoration hospital covers 13,000 square meters and boasts the nation’s most advanced restoration workshops.John Aquilina, Malta’s ambassador to China said that Shan’s speech showed a totally differentPalace Museum to foreign people. “China enjoys a long and profound culture a nd many of the national treasures have been preserved at the Palace Museum. It is no easy task to preserve them well. 70 ____”67-70 CEBA【2018-徐汇区-二模】Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box.

And even if they don’t find a way to solve their problems, it feels good to let off some steam. (67)_______________ How problems are discussed, though, can be the difference between halving a problem or doubling it.The term psychologists use for negative problem sharing is “co-rumination”. Co-rumination is the mutual encouragement to discuss problems repeatedly going over the same problems, anticipating future problems and focusing on negative feelings.(68)________________ In a study involving children aged seven to 15 years of age, researchers found that co-rumination in both boys and girls is associated with “high-quality” and close friendships. However, in girls, it was also associated with anxiety and depression (the same association was not found with the boys). And studies suggest that co-rumination isn’t just a problem for girls. Co-rumination with work colleagues can increase the risk of stress and burn out, one study suggests.(69)________________ In a group of adults, the effects of co-rumination was compared between face-to-face contact, telephone contact, texting and social media. The positive effects of co-rumination were found in face-to-face contact, telephone contact and texting, but not in social media. The negative aspects of co-rumination (anxiety) was found in face-to-face communication。
