He firmly believed (33) he put it, that “there is nothing incomprehensible (34) the universe“, and through painstaking work explained many of the phenomena thought to be “incomprehensible“ in his day. Einstein was also never afraid to (35) mistakes when facts (36) his theories wrong.

16、Second, Einsteins contributions showed the great importance of theoretical work to scientific effort. (37) he himself rarely worked in laboratories, the concepts he developed led (38) many of the scientific advances (39) have shaped modem technology.Third, Einstein believed very deeply that scientis

19、relativity and his other scientific works are not that hard to understand with a little study. But beyond learning Einsteins theories, his overall attitude (50) science as a tool to liberate humanity is something from which everyone can and should learn.（分数：20.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填

22、se or a disorder of the brainthan their peers over the course of the 12-year study.Robert Wilson at Rush University Medical Center in Chicago, Illinois, US, and colleagues followed 997 healthy Catholic nuns, priests and Christian brothers between 1994 and 2006. Early on in the study, participants co

23、mpleted a personality test to determine how conscientious they were.Based on answers to 12 questions such as “I am a productive person who always gets the job done“, they received a score ranging from 0 to 48. On average, volunteers scored 34 points in the test.Volunteers also underwent regular neur

24、ological examinations and cognitive tests. Over the lifetime of the study, 176 of the 997 participants developed Alzheimers disease. However, those with the highest score on the personality test40 points or abovehad an 89% lower chance of developing the debilitating condition than participants who r

25、eceived 28 points or lower.“These are people who control impulses, and tend to follow norms and roles,“ Wilson told New Scientist.Previous studies suggest that exercise and intellectual stimulation can decrease the risk of Alzheimers disease. But the link between self-discipline and a reduced risk o

26、f the illness remained strong even after researchers discounted these factors from their study. Subjects still had a 54% lower chance of developing the condition.Exactly why conscientiousness should have an impact on Alzheimers risk remains unclear, says Wilson. He notes that brain autopsies conduct

27、ed on 324 of the studys participants failed to resolve the mystery.Earlier work has linked the presence of plaques and protein tangles within the brain to Alzheimer. Yet, in general, the brains of those who scored highly on the conscientiousness test had as many plaques and protein tangles as those

28、of subjects who scored lower.Wilson suggests that more careful and conscientious individuals may have more active frontal brain regions, an area that is responsible for decision-making and planning. Increased activity in this region may perhaps compensate for a decline in function in other brain reg

29、ions, he speculates. Based on the new findings, doctors could perhaps consider certain patients at greater risk of dementia, says Ross Andel at the University of South Florida, US. “This is a study about identifying people at risk,“ he says.（分数：5.00）(1).How did the study evaluate every participants

30、sense of responsibility?A Through a 12-year observation.B On a neurological examination.C By a cognitive test.D By asking a group of questions.（分数：1.00）A.B.C.D.(2).Previous studies suggestA links between physical exercises and Alzheimer.B links between brain plaque and Alzheimer.C links between brai

32、ut the underlying reasons why conscientiousness has an impact on Alzheimers risk.C He suggests that people with more active frontal brain regions are more careful and conscientious.D He thinks that increased activity in frontal brain regions may compensate for a decline in function in other brain re

34、 the study, which one of the personalities below is more closely related to Alzheimers disease?A Scrupulousness.B Optimism.C Responsibleness.D Spontaneousness.（分数：1.00）A.B.C.D.九、Text 2(总题数：1，分数：5.00)Archaeopteryx had a pretty decent wingspan for a half-pound bird, more than 20 inches. That should ha

35、ve been ample to keep the crow-sized bird flying, or at least gliding, through the Jurassic skies. But as anyone whos ever watched a space shot knows, the toughest part of flying is the takeoff. And the first birds and their dinosaur ancestors just didnt have the specialized muscle power for liftoff

36、 that their modern counterparts do. Its a question scientists have been arguing about for more than 200 years: how did the first fliers generate the lift to conquer gravity and take to the air? A new study in the journal Nature shows how it could have been done.Fly-of-die? According to this popular

37、theory a tree-dwelling ancestral bird could have launched itself or fallen from its perch and managed to stay aloft with the panicked flapping of feathered forelimbs. That solves the gravity issue, but Luis Chiappe, a paleontologist at the Natural History Museum of Los Angeles County, poins out a pr

38、oblem. “We dont know of any bird ancestors that lived in trees.“A running start? This could have helped a bird like Archaeopteryx into the air, but its estimated top ground speed wasnt anywhere near fast enough for liftoff. Chiappe teamed with industrial aerodynamicist Phillip Burgers, who spends hi

39、s days designing fans and blowers, and just happens to have earned a Ph. D. studying avian flight. The two used aerodynamic theory and biomechanics to re-create the takeoff run of Archaeopteryx. During a run, the researchers found, the birds wings were able to rotate by 45 degrees at the shoulder, a

40、ngled forward like two large oars beating the air. That may have provided the extra burst of speed Archaeopteryx needed to outrun hungry predator or snap up a quick-running lizard. And, the new calculations show, it would also have generated sufficient velocity for takeoff. During the early phase of

41、 a run, Burgers explains, Archaeopteryxs wings acted more like an airplanes engines than its wings, providing more thrust than lift. Then, once in the air, Archaeopteryx would have rotated its wings back to horizontal, to maintain altitude. Burgers holds that modern birds do exactly the same thing.

42、Why did no one notice until now? “Were infatuated with lift,“ says Burgers, “because we cant generate it ourselves. “Chiappe and Burgers have shown that Archaeopteryx could have taken off from the ground, but whether or not it actually did may never be known. “I dont really care if Archaeopteryx fle

43、w or not,“ says Burgers. After all, people still ask the same question about chickens. “Does a chicken fly? Maybe, maybe not. But its wings help it get where it needs to go. Flying, it turns out, is just the continuation of running by other means.（分数：5.00）(1).The first paragraph points out that one
