[单项选择]When older people can no longer remember names at a cocktail party, they tend to think that their brainpower is declining. But a growing number of studies suggest that this assumption is often wrong.
Instead, the research finds, the aging brain is simply taking in more data and trying to sift through a clutter of information, often to its tong-term benefit.
The studies are analyzed in a new edition of a neurology book, "Progress in Brain Research."
Some brains do deteriorate with age. Alzheimer’s disease, for example, strikes 13 percent of Americans 65 and older. But for most aging adults, the authors say, much of what occurs is a gradually widening focus of attention that makes it more difficult to latch onto just one fact, like a name or a telephone number.

"It may be that distractibility is not, in fact, a bad thing," said Shelley H. Carson, a psychology researcher at Harvard whose work was cited in th
A. Brains do not deteriorate with age.
B. Distractibility may not be a bad thing.
C. Extra details steal people’s attention.
D. Older brains can transfer the information they’ve soaked up from one situation to another.
[不定项选择题]【材料一】一日,王教授应邀到甲机关举办一场关于职业道德与行为规范关系的专题讲座。会场里时常响起手机声,会议主持人不断地用手势提醒大家关闭手机,甚至打断王教授讲座,让大家保持会场秩序。次日王教授到乙机关举办同样的讲座,会场秩序井然,听讲座的每个人都自觉地关闭手机。王教授经过询问了解到,乙机关专门制定过一个规定,凡是参加机关会议的人,如果没关闭手机,手机在会场响起,则扣发当月奖金。而甲机关从来没有这样的规定。【材料二】某机关明文规定,因公出差到外地的,按照食宿补贴标准补贴。凡是食宿费用支出低于规定标准的,节约部分的50%归出差人所有。规定出台后,该机关的差旅补贴数额与规定出台之前相比明显下降。【材料三】某局长因犯贪污受贿罪,被判有期徒刑15年。在狱中,他忏悔道:“我不是法盲,也不是缺乏中华民族优秀道德传统的熏陶。我大学时本科学的专业是历史,硕士研究生读的是法律。但我却知法犯法,走向沉沦。究其原因,个人主义、享乐主义、拜金主义等腐朽没落的思想充斥了我的思想的每一个角落,使我在职业生涯中出现了一系列的道德失范和道德滑坡行为……”

A Messenger from the Past
His people said good-bye and watched him walk off toward the mountains. They had little reason to fear for his safety: the man was well dressed in insulated clothing and equipped with tools needed to survive the Alpine climate. However, as weeks passed without his return, they must have grown worried, then anxious, and finally
resigned. After many years everyone who knew him had died, and a note even a memory of the man remained.
Then, on an improbably distant day,
he came down from the mountain. Things had changed a bit: it wasn’t the Bronze Age anymore, and he was a celebrity.

Greenspace facilities are contributing to an important extent to the quality of the urban environment. Fortunately it is no longer necessary that every lecture or every book about this subject has to start with the proof of this idea. At present it is generally accepted, although more as a self-evident statement than on the base of a closely-reasoned scientific proof. The recognition of the importance of greenspaces in the urban environment is a first step on the right way, this does not mean, however, that sufficient details are known about the functions of greenspace in towns and about the way in which the inhabitants are using these spaces. As to this rather complex subject I shall, within the scope of this lecture, enter into one aspect only, namely the recreative function of greenspace facilities.
