processing and storing those memories long before it s time for bed and continues to do so even while you re thinking about and doing other things Recent studies have shown that the parts of the brain that we use to learn a task become active again during sleep This activity scientists suggest could be the brain transferring memories from short term to long term storage But the brain doesn t necessarily wait until the lights are out to begin processing those memories To find out how the brain handles memories during waking hours scientists gave 15 volunteers two tasks each requiring different parts of the brain to learn In one task the subjects learned how to drive in a virtual 虚拟的 town and then searched the town for an object In the second task they learned to predict where a series of dots would appear on a screen Using a special machine the researchers scanned the volunteers brains right before and right after the tasks They compared the two images to see whether the regions of the brain involved in learning the task were still active even after the task was completed After a break the scientists took a third image of each participant s brain They wanted to determine whether these regions in the brain continued to be active after more time had passed and they discovered that for at least an hour after a learning task the brain stayed active It appeared to continue processing the new information Furthermore the images showed that distracting the subjects doesn t affect their ability to store memories The processing continues even when they re thinking about or doing other things Some scientists say this could mean that sleep isn t essential for storing 2 memories Others disagree Until that s settled it s probably still better to be on the safe side getting plenty of sleep 1 The fact that the parts of the brain that we use to learn a task become active again during sleep may suggest A we are dreaming a dream about the lessons we learned in the daytime B we can t have a good sleep if we work too hard before going to bed C the brain stays active even when we are in deep sleep at night D the brain is transferring memories from short term to long term storage 2 The scientists took a third image of each participant s brain to A find whether the brain continues processing the new information after more time had passed B see whether the regions of the brain involved in learning the task were working actively C prove different parts of the brain are involved in learning D discover whether the processing continues even when people are doing other things 3 The underlined word distract in the sixth paragraph probably has the closest meaning to A attract B divert C solve D consider 4 It can be inferred from the passage that A sleep isn t essential for storing memories B getting plenty of sleep is a waste of time C scientists haven t agreed on whether sleep helps memory D sleep on the safe side is good to us B B Although it might have happened anywhere my encounter with the green banana started on a steep mountain road in the central area of Brazil I was driving up through beautiful countryside when the radiator 水箱 began to leak I stopped at the next village which consisted of a small store and a few houses People came over to look That s easy to fix a man said He sent a boy running for some green bananas He patted me on the shoulder assuring me that everything would work out Green bananas he smiled Everyone agreed We chatted casually while all the time I was wondering what they could 3 possibly do to my radiator with their green bananas I did not ask them though as that would show my ignorance so I talked about the beauty of the land that lay before our eyes Huge rock formations like Sugarloaf Mountain in Rio de Janeiro rose up all around us Do you see that tall one right over there asked the man pointing to a particularly tall slender pinnacle 尖端 of dark rock That rock marks the center of the world I looked to see if he was teasing me but his face was serious He in turn inspected me carefully as if to make sure I grasped the significance of his statement The occasion called for some show of recognition on my part The center of the world I repeated trying to show interest He nodded The absolute center Everyone around here knows it At that moment the boy returned with an armful of green bananas The man cut one in half and pressed the cut end against the radiator jacket The banana melted into a glue against the hot metal stopping the leaks instantly I was so astonished at this that I must have looked rather foolish and everyone laughed They then refilled my radiator and gave me extra bananas to take along An hour later after using the green banana once more my radiator and I reached our destination It took me a little longer to fully grasp the importance of the rock which the villagers believed marked the center of the world I had at first doubted their claim as I knew for a fact that the center was located somewhere else in New England After all my grandfather had come from there But gradually I realized the village people had a very reasonable belief and I agreed with them We all tend to regard the center as that special place where we are known where we know others where things mean much to us and where we ourselves have both identity and meaning family school town and local region could all be our center of the world The lesson which gradually dawned on me was actually very simple Every place has special meanings for the people in it and in a certain sense every place represents the center of the world The world has numerous such centers and none of the students or travelers can experience all of them But once a conscious breakthrough to a second center is made a life long perspective and collection can begin The cultures of the world are full of unexpected green bananas with special 4 value and meaning They have been there for ages ripening slowly perhaps waiting patiently for people to come along to encounter them In fact a green banana is waiting for all of us if we would leave our own centers of the world in order to experience other places 5 What s the author s reaction to the man s remarks on the center of the earth A He thought the man was serious about what he said B He thought that the man was telling the truth C He thought that the man was telling a story D He thought the man was making fun of him 6 What does the author come to learn from the man s remarks A The rock mentioned by the man is really the center of the world for everyone B There are lots of such rocks in the world representing the center of the world C There is only one center in the world that is actually in New England D As a matter of fact the center of the world does not exist in his opinion 7 What can we infer from the last paragraph A A green banana refers to a banana that is not ripe B A green banana is something that can be used to repair a leaking radiator C A green banana refers to a certain culture that is unknown to an outsider D A green banana is something useful that we find unexpectedly 二 短文填空 根据短文内容
