Bob Crossley, a human-resources expert notices this in the job applications that come across his desk every day. "It's amazing how many candidates eliminate themselves ," he says.2．"Resumes(简历)arrive with stains. Some candidates don't bother to spell the company's name correctly. Once I see a mistake, I eliminate the candidate, "Crossley concludes. "if they cannot take care of these details, why should we trust them with a job?"3．Can we pay too much attention to details? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward. "To keep from losing the forest for the trees, "says Charles Garfield, associate professor at the University of California, San Francisco, "we must constantly ask ourselves how the details we're working on fit into the larger picture. If they don't we should drop them and move to something else."4．Garfield compares this process to his work as a computer scientist at NASA. "The Apollo moon launch was slightly off-course 90 percent of the time." says Garfield. "But a successful landing was still likely because we knew the exact 'coordinates of our goal. This allowed us to make adjustments as necessary. "Knowing where we want to go helps us judge the importance of every task we undertake.5．Too often we believe what accounts for others' success is some special secret or a lucky break (机遇). But rarely is success so mysterious. Again and again, we see that by doing little things within our grasp well, large rewards follow.

单选题Mind-reading Machine A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what's happening in their brains. When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send cells in your brain called neurons are responsible for this processing. The fMRI (functional Magnetic Resonance Imaging) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at. Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize which parts of the brain receive more oxygen-rich blood--and therefore, which parts are working to process information. An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images. The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see. In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.

单选题阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子作出判断。 An Awful Afternoon Sometimes I feel that being the mother of three small children is like running a large circus(马戏团). One afternoon last week, my three sons were playing peacefully in the back-yard, throwing the ball from one to the other. I jumped at the chance to talk to one of my friends on the phone, but before I got to the phone, I could tell that the boys had begun to quarrel with each other over something. I rushed out to make peace, but before I got there, Charles had begun to fight over this. Even David, the oldest boy, who won't usually fight with anybody over anything, was involved. First, I made them stop fighting, and then I examined Mark's eye. I decided that it wasn't going to develop into a black eye, but I felt that they should suffer at least a little for what they had done. "I'm going to speak to your father about these when he comes home tonight," I said. "He and I will think of how to punish you. " Things were pretty quiet after that for about half an hour, and then Charles broke a glass in the kitchen sink, and at almost the same moment, Mark fell out of the apple tree. I suppose I will be able to laugh at all these things someday. In the meantime, I just pray to heaven for patience.

单选题Whether people in recent times have become more protective of their personal space is hard to say. Yet studies of airlines show passengers strong desire to have some space to themselves. In a recent survey from Trip Advisor, travelers said if they had to pay for certain benefits, they would rather have larger seats and more legroom than extra food. Scholars know that commuters hold newspapers in front of them to read, but also to shield themselves from strangers. They know that college students unconsciously sit at positions where they can avoid direct eye contact. "If you videotape people at a library, it's very clear what scat people will take," said Professor Dane Archer. One of the comer seats will go first ,followed by the chair diagonally (斜对角) opposite because that is the farthest away. "If you break those rules, it's fascinating, "Archer added, "People will pile up books as if to make a wall." If someone sits too close to you in the library, you will pile up books in front of" you so as toA. hide your awkwardness.B. show indifference to the person.C. protect your personal space.D. give the person an angry look.

单选题Bats, tortoises, snakes, frogs, even insects like butterflies, hibernate more or less completely. Some, like the squirrels, sleep during coldest weather but are aroused by a warm spell. During hibernation, the temperature of an animal's body drops drastically. Breathing and heart-beats almost cease. Another instinctive method of avoiding intense cold is to escape by means of migration. Wild swans, seagulls, swallows and cuckoos are a few of the very many kinds of birds which fly thousands of miles, twice a year, to avoid cold. Many animals, especially those of the Arctic reindeer of Europe, move southward towards the forests when winter approaches. They return to the northern area when the warmth of spring begins to be sensed. Arctic reindeers of Europe avoid the severe cold in winter byA. hibernation.B. migration.C. staying in a" secret place".D. growing thick fur.

单选题 Forecasting Methods There are several different methods that can be used to create a forecast. The method forecaster chooses depends upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents, and the degree of accuracy or confidence needed in the forecast. The first of these methods is the persistence method; the simplest way of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 87 degree today, the persistence method predicts that it will be sunny and 87 degree tomorrow. If two inches of rain fell today, the persistence method would predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persistence method usually breaks down and is not the best forecasting method to use. The trends method involves determining the speed and direction of movement for fronts, high and low pressure centers, and areas of clouds and precipitation. Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1,000 miles west of your location and moving to the east at 250 miles per day, suing the trends method you would predict it to arrive in your area in 4,days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. If they slow down, speed up, change intensity, or change direction, the trends forecast will probably not work as well. The climatology method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over many years to make the forecast. For example, if you were using the climatology method to predict the weather for New York City on July 4th, you would go through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen time of year. If the pattern is quite unusual for the given time of year, the climatology method will often fail. The analog method is a slightly more complicated method of producing a forecast. It involves examining today's forecast scenario and remembering a day in the past when the weather scenario looked very similar (an analog). The forecaster would predict that the weather in this forecast will behave the same as it did in the past. The analog method is difficult to use because it is virtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations they were in the previous time. Even small differences between the current time and the analog can lead to very different results.

An idea hit David one evening. 【60】 only his mothers cane didn’t slip on ice ,he thought. "That''s it!" David realized. "What if I fixed your cane to a nail stretched out of the bottom?" he asked his mother. His mother told him," 【61】 it would scratch floors. " "It looks like a ball-point pen. You take your hand 【62】 the button and the nail returns back up." Hours later the cane was finished. David and his father, Jeff, 【63】 as Suzan used it to walk 50 feet across the 【64】 . "It works!" she said . In July 1989, David was declared national winner at the annual" INVENT AMERICA!" ceremony in Washington D.C..
