听力原文： A recent study reveals higher education tends to speed up mental decline and leave elderly people at a loss for words.
Participants in the study were all more than 70 years old. They were tested up to four times between 1993 and 2000 on their ability to remember 10 common words read aloud to them. The most educated test subjects were found to experience a steeper decline during the years in remembering the list.
Individuals with a better education seem to have a higher starting point in their word memory, and so may initially remember more total words than their less educated peers.
The more education one has, the more words one will know to begin with. It appears the more you know, the more you have to lose.
The explanation for the faster decline of more educated individuals could possibly be they were unable to access memory tricks they once relied on to help them remember things. For a while, these strategies can help them compensate, but as they get older, their brains become overwhelmed and they can no longer use those strategies.
Because the study didn't follow people across their entire life spans, there could be other unseen factors. For example, those with less education may start their cognitive decline earlier.
The possibly protective nature against conditions like dementia could be due to a correlation between higher education and generally higher living standards, like access to better health care and better eating habits. The things that make a healthy body make a healthy mind.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Joyce Carol Oates published her first collection of short stories, By The North Gate, in 1963, two years after she had received her master's degree from the University of Wisconsin and become an instructor of English at the University of Detroit. Her productivity since then has been prodigious, accumulating in less than two decades to nearly thirty titles, including novels, collections of short stories and verses, plays, and literary criticism. In the meantime, she has continued to teach, moving in 1967 from the University of Detroit to the University of verses, in Ontario, and, in 1978, to Princeton University. Reviewers have admired her enormous energy, but find a productivity of such magnitude difficult to assess.
In a period characterized by the abandonment of so much of the realistic tradition by authors such as John Barth, Donald Barthelme, and Thomas Pynchon, Joyce Carol Oates has seemed at times determinedly old fashioned in her insistence on the essentially mimetic quality of her fiction. Hers is a world of violence, insanity, fractured love, and hopeless loneliness. Although some of it appears to come from her own direct observations, her dreams, and her fears, much more is clearly from the experiences of others. Her first novel, With Shuddering FaU(1964), dealt with stock car racing, though she had never seen a race. In Them (1969) she focused on Detroit from the Depression through the riots of 1967, drawing much of her material from the deep impression made on her by the problems of one of her students. Whatever the source and however shocking the events or the motivations, however, her fictive world remains strikingly akin to that real one reflected in the daily newspapers, the television, news, and talk shows, and the popular magazines of our day.

听力原文： We continue the first in a new series of reports from time to time on raising children. Today we discuss some ways to help bed-wetters stay dry all night long.
Researchers say the young people who do it are usually physically and emotionally normal. They say the causes of bed-wetting are not known. But they think most cases probably result from a mix of things including slower physical development. Often there is a strong family history of bed-wetting.
The good news is that most children grow out of it over time. So, until that happens, here are some steps that might help.
First, consider a limit on the amount of liquid a child drinks before bedtime. Also, make sure children use the bathroom right before bed—an empty bladder at bedtime should help.
Some parents wake their children at night to use the bathroom. Others set a timer to sound, so children wake up on their own.
The Mayo Clinic says even going to bed 30 minutes earlier can help some children stop wetting the bed.
Some parents put a plastic cover on the bed, then a cloth sheet, followed by an additional set of plastic and cloth sheets. This way, it is easy to remove wet coverings and have a dry set ready.
Doctors say the first thing a parent should do about bed-wetting is talk to their child's doctor. When nothing else works, doctors sometimes give medicines to reduce urine production, or antidepressant drugs or both.
