单项选择题 根据下列文章,请回答 36～40 题。 Sleep Necessary for Memories Burning the midnight oil before an exam or interview does harm to the performance according to a recent research which found that sleep is necessary for memories to be taken back into the brain．A good night’s sleep within 30 hours of trying to remember a new task is a required condition of having good recall in the weeks ahead，scientists have found．The research，published in the December issue of Nature Neuroscience，showed that it was the act of sleep，rather than the simple passage of time，that was critical for long—term memory formation．“We think that getting that first night’s sleep starts the process of memory consolidation(巩固)，”said Robert Stick gold，a sleep researcher at Harvard Medical School who conducted the．1atest study．“It seems that memories normally wash out of the brain unless some process nails them down．My suspicion is that sleep is one of those things that does the nailing down，”Professor Stick gold said．With about one in five people claiming that they are SO chronically short of sleep that it affects their daily activities。the latest work emphasizes the less well-understood side effect—serious memory impairment(损害)．Volunteers in an experiment found it easier to remember a memory task if they were allowed to sleep that night．But for those kept awake, no amount of subsequent sleep made up for the initial loss．Professor Stick gold’s team trained 24 people to identify the direction of three diagonal(斜线形的)bars flashed for a sixtieth of a second on a computer screen full of horizontal(水平的)stapes．Half of the subjects were kept awake that night，while the others slept．Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers．Those who slept the first night were significantly and consistently battler at remembering the task while the second group showed no improvement despite enjoying two nights of catch—up sleep． 第 36 题 The research published in Nature Neuroscience showed that what was essential to the formation of long-term memory wasA．intelligence．B．timeC．foodD．sleep

单项选择题 根据下列文章,请回答 46～50 题。 Read With Greater Speed Do you have difficulty reading in class? If S0，a special reading program that helps match sounds with letters could speed up your brain．At least one out of every five elementary school students in the US has trouble learning to read．even when the students are good at other subjects．___________ (1)Researchers from Yale University, US，studied a group of children from New York and Connecticut State。As part of the study,37 struggling readers received special tutoring．Every day，instructors worked with them on recognizing how written letters represent units of sound called phonemes(音素)．___________ (2)By the end of the school year, these children could read faster than before．They also made fewer mistakes，and understood more of what they read than they could earlier in the year．As part of their study, the researchers used a special machine to take action photos of the students’ brains．___________ (3)This is the same part of the brain that becomes active when good readers read．This activated brain area appears to include a structure that helps people recognize familiar written words quickly．In lower level readers，this structure remains inactive．A year later，the brain structure was still working hard in the students who had gone through the special tutoring，and they continued to do well in reading tests___________ (4)However, some researchers still doubt the study．___________ (5) A．Many adults are interested in matching sounds with letters.B．The students also practiced reading aloud and spelling．C．The biggest challenge for many of these kids，scientists say, is matching sounds with letters．D．Another group in the study who went through a more traditional reading program didn’t show the same progress．E．The pictures showed an increase in activity in the back of the brain on the left side．F．They believe that reading without making any noise or linking words to sounds is more efficient． 第 46 题 请选择（1）处最佳答案。
