Signs barring cell-phone use are a familiar sight to anyone who has ever sat in a hospital waiting room. But the【C1】______popularity of electronic medical records has forced hospital-based doctors to become【C2】______on computers throughout the day, and desktops—which keep doctors from bedsides— are【C3】______giving way to wireless devices. As clerical loads increased, "something had to【C4】______, and that was always face time with patients," says Dr. Bhakti Patel, a former chief resident in the University of Chicago's internal-medicine program. In fall 2010, she helped【C5】______a pilot project in Chicago to see if the iPad could improve working conditions and patient care. The experiment was so【C6】______that all internal-medicine residents at the university now get iPads when they begin the program. Johns Hopkins' internal-medicine program adopted the same【C7】______in 2011. Medical schools at Yale and Stanford now have paperless, iPad-based curriculums. "You'll want an iPad just so you can wear this" is the slogan for one of the new lab coats【C8】______with large pockets to accommodate tablet computers. A study of the University of Chicago iPad project found that patients got tests and【C9】______faster if they were cared for by iPad-equipped residents.

Physical activity does the body good, and there's growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own,【C1】______to have higher GPAs and better scores on standardized tests. In a【C2】______of 14 studies that looked at physical activity and academic【C3】______, investigators found that the more children moved, the better their grades were in school,【C4】______in the basic subjects of math, English and reading. The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to【C5】______on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U. S.【C6】______in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be【C7】______exclusive. Physical activity can improve blood【C8】______to the brain, fueling memory, attention and creativity, which are【C9】______to learning. And exercise releases hormones that can improve【C10】______and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies when they're running around, they may actually be exercising their brains as well.A)attendance I)moodB)consequently J)mutuallyC)current K)particularlyD)depressing L)performanceE)dropping M)reviewF)essential N)surviveG)feasible O)tend H)flow

Many men and women have long bought into the idea that there are "male" and "female" brains, believing that explains just about every difference between the sexes. A new study【C1】______ that belief, questioning whether brains really can be distinguished by gender. In the study, Tel Aviv University researchers【C2】______ for sex differences throughout the entire human brain. And what did they find? Not much. Rather than offer evidence for【C3】______ brains as "male" or "female," research shows that brains fall into a wide range, with most people falling right in the middle. Daphna Joel, who led the study, said her research found that while there are some gender-based【C4】______ , many different types of brain can't always be distinguished by gender. While the "average" male and "average" female brains were【C5】______ different, you couldn't tell it by looking at individual brain scans. Only a small【C6】______ of people had "all-male" or "all-female" characteristics. Larry Cahill, an American neuroscientist(神经科学家), said the study is an important addition to a growing body of research questioning【C7】______ beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,【C8】______ of gender. "There's a mountain of evidence【C9】______ the importance of sex influences at all levels of brain function,"he told The Seattle Times. If anything, he said, the study【C10】______ that gender plays a very important role in the brain—"even when we are not clear exactly how.

The ocean is heating up. That's the conclusion of a new study that finds that Earth's oceans now【C1】______ heat at twice the rate they did 18 years ago. Around half of ocean heat intake since 1865 has taken place since 1997, researchers report online in Nature Climate Change. Warming waters are known to【C2】______ to coral bleaching(珊瑚白化)and they take up more space than cooler waters, raising sea【C3】______ . While the top of the ocean is well studied, its depths are more difficult to【C4】______ . The researchers gathered 150 years of ocean temperature data in order to get a better【C5】______ of heat absorption from surface to seabed. They gathered together temperature readings collected by everything from a 19th century【C6】______ of British naval ships to modern automated ocean probes. The extensive data sources,【C7】______ with computer simulations(计算机模拟), created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel【C8】______ . About 35 percent of the heat taken in by the oceans during the industrial era now resides at a【C9】______ of more than 700 meters, the researchers found. They say they're【C10】______ whether the deep-sea warming canceled out warming at the sea's surface.A)absorb I)heightsB)combined J)indifferentC)contribute K)levelsD)depth L)mixedE)emissions M)pictureF)excursion N)unsureG)explore O)voyageH)floor

When someone commits a criminal act, we always hope the punishment will match the offense. But when it comes to one of the cruelest crimes—animal fighting—things【C1】______ work out that way. Dog-fighting victims are【C2】______ and killed for profit and "sport," yet their criminal abusers often receive a【C3】______ sentence for causing a lifetime of pain. Roughly half of all federally-convicted animal fighters only get probation(缓刑). Some progress has been made in the prosecution(起诉)of animal fighters. But federal judges often rely heavily on the U. S. Sentencing Guidelines when they【C4】______ penalties, and in the case of animal fighting, those guidelines are outdated and extremely【C5】______ . The U. S. Sentencing Commission, which【C6】______ these sentencing guidelines, is revisiting them, proposing to raise the minimum sentence from 6-12 to 21 -27 months. This is a step in the right【C7】______ , but we'd like to see the U. S. Sentencing Commission make further changes to the guidelines. Along with this effort, we're working with animal advocates and state and federal lawmakers to【C8】______ anti-cruelty laws across the country, as well as supporting laws and policies that assist overburdened animal【C9】______ that care for animal fighting victims. This help is【C10】______ important because the high cost of caring for animal victims is a major factor that prevents people from getting involved in cruelty cases in the first place.A)convenient I)methodB)creates J)minimalC)critically K)rarelyD)determine L)sheltersE)direction M)strengthenF)hesitate N)sufferingsG)inadequate O)torturedH)inspired

Children do not think the way adults do. For most of the first year of life, if something is out of sight, it's out of mind. If you cover a baby's【C1】______toy with a piece of cloth, the baby thinks the toy has disappeared and stops looking for it. A 4-year-old may【C2】______that a sister has more fruit juice when it is only the shapes of the glasses that differ, not the【C3】______of juice. Yet children are smart in their own way. Like good little scientists, children are always testing their child-sized【C4】______about how things work. When your child throws her spoon on the floor for the sixth time as you try to feed her, and you say, "That's enough! I will not pick up your spoon again!" the child will【C5】______test your claim. Are you serious? Are you angry? What will happen if she throws the spoon again? She is not doing this to drive you【C6】______: rather, she is learning that her desires and yours can differ, and that sometimes those【C7】______are important and sometimes they are not. How and why does children's thinking change? In the 1920s, Swiss psychologist Jean Piaget proposed that children's cognitive(认知的)abilities unfold【C8】______, like the blooming of a flower, almost independent of what else is【C9】______in their lives. Although many of his specific conclusions have been【C10】______or modified over the years, his ideas inspired thousands of studies by investigators all over the world.A)advocate I)immediatelyB)amount J)naturallyC)confirmed K)obtainingD)crazy L)primarilyE)definite M)protestF)differences N)rejectedG)favorite O)theoriesH)happening

For many Americans, 2013 ended with an unusually bitter cold spell. Late November and December【C1】______early snow and bone-chilling temperatures in much of the country, part of a year when, for the first time in two【C2】______, record-cold days will likely turn out to have outnumbered record-warm ones. But the U. S. was the exception-. November was the warmest ever【C3】______, and current data indicates that 2013 is likely to have been the fourth hottest year on record. Enjoy the snow now, because【C4】______are good that 2014 will be even hotter, perhaps the hottest year since records have been kept. That's because, scientists are predicting, 2014 will be an El Nino year. El Nino, Spanish for "the child" ,【C5】______when surface ocean waters in the southern Pacific become abnormally warm. So large is the Pacific, covering 30% of the planet's surface, that the【C6】______energy generated by its warming is enough to touch off a series of weather changes around the world. El Ninos are【C7】______with abnormally dry conditions in Southeast Asia and Australia. They can lead to extreme rain in parts of North and South America, even as southern Africa【C8】______dry weather. Marine life may be affected too: El Ninos can【C9】______the rising of the cold, nutrient-rich(营养丰富的)water that supports large fish【C10】______, and the unusually warm ocean temperatures can destroy coral(珊瑚).A)additional I)logicallyB)associated J)occursC)bore K)populationsD)chances L)realizeE)communicated M)reduceF)decades N)sawG)experiences O)specificH)globally

Scholars of the information society are divided over whether social inequality decreases or increases in an information-based society. However, they generally agree with the idea that inequality in the information society is【C1】______different from that of an industrial society. As informatization progresses in society, the cause and structural nature of social inequality changes as well. It seems that the information society【C2】______the quantity of information available to the members of a society by revolutionizing the ways of using and exchanging information. But such a view is a【C3】______analysis based on the quantity of information supplied by various forms of the mass media. A different【C4】______is possible when the actual amount of information【C5】______by the user is taken into account. In fact, the more information【C6】______throughout the entire society, the wider the gap becomes between "information haves" and "information have-nots" , leading to digital divide. According to recent studies, digital divide has been caused by three major【C7】______: class, sex, and generation. In terms of class, digital divide exists among different types of workers and between the upper and middle classes and the lower class. With【C8】______to sex, digital divide exists between men and women. The greatest gap, however, is between the Net-generation,【C9】______with personal computers and the Internet, and the older generation,【C10】______to an industrial society.A)accustomed I)flowsB)acquired J)fundamentallyC)assembly K)interpretationD)attribute L)passiveE)champions M)regardF)elements N)respectivelyG)expands O)superficialH)familiar

We all know there exists a great void (空白) in the public educational system when it comes to【C1】______ to STEM (Science, Technology, Engineering and Mathematics) courses. One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years. She noticed there was a real void in quality STEM education at all【C2】______ of the public educational system. She said, "I started Engineering For Kids (EFK) after noticing a real lack of math, science and engineering programs to【C3】______ my own kids in." She decided to start an afterschool program where children【C4】______ in STEM-based competitions. The club grew quickly and when it reached 180 members and the kids in the program won several state【C5】______, she decided to devote all her time to cultivating and【C6】______ it. The global business EFK was born. Dori began operating EFK out of her Virginia home, which she then expanded to【C7】______ recreation centers. Today, the EFK program【C8】______ over 144 branches in 32 states within the United States and in 21 countries. Sales have doubled from $ 5 million in 2014 to $ 10 million in 2015, with 25 new branches planned for 2016. The EFK website states, "Our nation is not【C9】______ enough engineers. Our philosophy is to inspire kids at a young age to understand that engineering is a great【C10】______.
