问题     The city has always been an engine of intellectual life, from the 10-century cafes of London, where citizens gathered to discuss chemistry and politics, to the Left Bank bars of modern Paris, where Picasso talked about modern art. Without the metropolis, we might not have had the great art of Shakespeare.
    And yet, city life isn’t easy. Now scientists have begun to examine how the city affects the brain, and the results are depressing. Just being in the urban environment, they have found, impairs(损害)our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory and suffers from reduced self-control. While it’s long been recognized that city life is exhausting, this new research suggests that cities actually dull our thinking, sometimes dramatically so.
    One of the main forces at work is a complete lake of nature, which is surprisingly beneficial for the brain. Studies have demonstrated, for instance, that hospital patients recover more quickly when they can see trees from their windows, and that women living in public housing are better able to focus when their apartments overlook a lawn. Even these glimpses of nature improve brain performance, it seems, because they provided a mental break from the urban life.
    This research arrives just as humans cross an important milestone(里程碑). For the first time in history, the majority of people live in cities. Instead of inhabiting wide-open spaces, we’re crowded into concrete jungles, surrounded by traffic and millions of strangers. In recent years, it’s become clear that such unnatural surroundings have important implications for our mental and physical health, and can powerfully alter how we think.
What is the factor mentioned in the third paragraph that helps the hospital patients recover more quickly?

选项 A、Nature.
B、Better treatment.
C、Experienced doctors.
D、Good medicine.

答案A

解析 本题为事实细节题,提问的是第三段中提到的哪个因素能帮助病人迅速康复。文章第三段探讨城市对人们大脑和思维造成破坏的原因,第一句话“One of the main forces at work isa complete lack of nature,which is surprisingly beneficial for the brain.”就明确提到其中一个重要的原因就是缺乏自然环境,而该段后面的句子就是在分析自然“nature”的作用,其中包括了病人康复这一例子,显然病人能很快康复也是因为自然环境的作用。因此答案为A)。
