11、rowing up in a city, a vast global survey has found, has a lifelong negative impact on a personas ability to navigate. When looking for a half-remembered restaurant in a poorly-lit side street, it seems a countryman would be a more useful companion.In the new study, scientists led by Antoine Coutrot

12、 at the University of Nantes and Hugo Spiers at University College London describe how they used a data set gathered from players of a computer game called Sea Hero Quest, which tests way-finding skills by asking players to memorise a map showing the location of checkpoints and then measuring how we

13、ll players can guide a boat to find them. The game was released in 2016 and all players have since been asked for basic information about themselves, including their age, gender, home country, and whether or not they grew up in a city.From that database, Dr Spiers and his colleagues examined a subse

14、t of 442,000 players from 38 countries. They found that the strongest indicator of a high score was a players age, older people performed relatively poorly. But the benefit of rural living was strong enough to offset some of that. Data showed that a 70-year-old who grew up in the countryside had the

15、 navigational abilities of an average 60-year-old across the data set.The gap between the navigation skills of rural and city people was the largest in America, and the researchers think they know why. They gave each country a complexity score by analysing how the streets were laid out in its larges

16、t cities. And they found that countries dominated by simple layouts of grid-based (基于网格的) cities (most common in America and Argentina) dragged down navigation skills more than growing up in a city based around more complicated networks of streets, such as Prague.Dr Spiers says that the brains navig

17、ational abilities probably weaken in the less challenging city environment because they are not being used as much. Although cities may appear more complicated, they also feature more clues to help residents find their way, such as numbered streets. As many city people on a visit to the countryside

18、say, one field tends to look much the same as another, so there are fewer external landmarks to help guide the way.1.What did the players have to do when playing Sea Hero Quest ?A.Draw the right way to checkpoints on a map.B.Find out the right map of checkpoints as fast as possible.C.Choose the prop

But now a new study has found that sitting is also bad f

53、or your brain.A study published last week, conducted by Dr. Prabha Siddarth at the University of California, showed that sedentary (久坐的) behavior is associated with reduced thickness of the medial temporal lobe, a brain area that is critical to learning and memory.The researchers asked a group of 35

54、 healthy people, ages 45 to 70, about their activity levels and the average number of hours each day spent sitting and then scanned their brains. They found that the subjects who reported sitting for longer periods had the thinnest medial temporal lobes. It means that the more time you spend in a ch

55、air, the worse it is for your brain health, resulting in possible damage to learning and memory.What is also interesting is that this study did not find a significant association between the level of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise,

56、may not be enough to protect you from the harmful effects of sitting.It then surprisingly turned out that you dont even have to move much to improve cognition; just standing will do the trick. For example, two groups of subjects were asked to complete a test while either sitting or standing. Partici

57、pants are presented with conflicting stimuli, like the word “green” in blue ink, and asked to name the color. Subjects thinking on their feet beat those who sat by a 32-millisecond margin.The cognitive effects of severe physical exercise are well known. But the possibility that standing more and sit

58、ting less improves brain health could lower the bar for everyone.I know, this all runs counter to received ideas about deep thought, from our grade school teachers, who told us to sit down and focus, to Rodins famous “Thinker,” sitting with chin on hand.They were wrong. You can now all stand up.12.W

59、hat can we infer from Paragraphs 3 and 4?A.Severe exercise can lessen the damage of sitting.B.Severe exercise can greatly improve our brain health.C.Sedentary behavior will possibly damage our brain.D.Brain health has nothing to do with sedentary behavior.13.What does the underlined word “margin” in

60、 Paragraph 5 mean?A.Blank.B.Edge.C.Increase.D.Difference.14.What is the received idea about deep thought?A.Sitting more is good for our mental health.B.Sitting is better when we think.C.Thinking more can improve our cognition.D.We should stand while thinking.15.What does the text mainly tells us?A.P

61、eople tend to sit while thinking.B.Standing more can make our brain healthier.C.Physical exercise can improve our brain health.D.Sedentary behavior leads to countless health problems.【答案】12.C13.D14.B15.B【分析】这是一篇说明文。我们知道，每天长时间坐着对健康有无数的影响，比如患心脏病的风险更高。但现在一项新研究发现，久坐也对大脑有害。文章主要说明了研究发现站着思考能够使人的大脑更加健康、思维更加

62、敏捷的这一现象，介绍了这一研究过程和研究意义。12.推理判断题。根据第三段中“It means that the more time you spend in a chair the worse it is for your brain health, resulting in possible damage to learning and memory.(这意味着，你在椅子上坐的时间越久，就越不利于你的大脑健康，可能会导致学习和记忆受损)”以及第四段中“What is also interesting is that this study did not find a significant

63、 association between the level of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise, may not be enough to protect you from the harmful effects of sitting.(有趣的是，这项研究没有发现身体活动水平和大脑区域厚度之间有显著的关联，这表明运动，甚至是剧烈运动，可能不足以保护你免受坐姿的有害影响)”可推知，久坐的行为可能会损害我们的大脑。故选C。13.词

64、义猜测题。根据画线词上文“For example, two groups of subjects were asked to complete a test while either sitting or standing. Participants are presented with conflicting stimuli, like the word “green” in blue ink, and asked to name the color.(例如，两组受试者被要求在坐着或站着时完成一项测试。受试者看到相互矛盾的刺激物，比如用蓝色墨水写的单词“绿色”，然后被要求说出这种颜色)”以及

65、“Subjects thinking on their feet beat those who sat by a 32-millisecond”可知，站着思考的受试者会以32毫秒的差异击败坐着的受试者，故margin在此处意为“差异”。A. Blank. 空白；B. Edge.边缘；C. Increase.增加；D. Difference.差异。故选D。14.细节理解题。根据倒数第二段“I know, this all runs counter to received ideas about deep thought, from our grade school teachers, who t

66、old us to sit down and focus, to Rodins famous “Thinker,” sitting with chin on hand.(我知道，这一切都与我们从小学老师那里得到的关于深思熟虑的想法背道而驰，他们让我们坐下集中注意力，还有罗丹著名的“思想者”，手托下巴坐着)”可知，我们以前接受的关于深思熟虑的想法是坐着思考更好。故选B。15.主旨大意题。根据第一段中的“But now a new study has found that sitting is also bad for your brain.(但现在一项新的研究发现，坐着对大脑也有害)”以及第三段最后一句“It means that the more time you spend in a chair the worse it is for your brain health, resulting in possible damage to learning and memory.(这意味着，你在椅子上坐的时间越久，就越不利于你的大脑健康，可能会导致学习和记忆受损)”结合文章主要说明了研究发现站着思考能够使人的大脑更加健康、思维更加敏捷的这一现象，介绍了这一研究过程和研究意义。可知，文章主要告诉我们多站可以使我们的大脑更健康。故选B。
