第1题
听力原文： Crime has its own cycles，a magazine reported some years ago. Police records show a surprising relation between changes in the season and crime patterns.
The pattern of crime has changed very little over a long period of years. Murder reaches its high during July and August，as do other violent attacks. Murder，in addition，is more than seasonal；it is a weekend crime. It is also a nighttime crime: 62 percent of murders are committed between 6 P. m. and 6 a. m. One is most likely to be robbed between 6 P. m. and 2 a. m. on a Saturday night in December，January，or February. Except for one strange statistic，May is the least criminal month of all.
Apparently our intellectual season cycles are completely different from our criminal patterns. Professor Huntington made a lot of studies to discover the seasons when people read serious books，attend scientific meetings，and make the highest scores on examinations. In all examples，he found a spring peak and an autumn peak separated by a summer low. On the other hand，Professor Huntington's studies showed that June is the peak month for suicides and for admitting patients to mental hospital. June is also a peak month for marriages!
Possibly，high temperature and humidity bring on our strange and surprising summer actions，but police officers are not so sure. “There are，of course，no proof of a relation between humidity and murder”，they say. “Why murder's high time should come in the summer time we really don't know”.

A．Different kinds of crimes。
B．Increasingly high crime rate in the U.S.
C．Seasonal changes in the natural environment．
D．The relations between changes in the season and crime patterns．
第2题
Unlike the summer high in crimes of bodily harm, robbing has a different cycle. You are most likely to be robbed between 6 p.m. and 2am. on a Saturday night in December, January, or February. The month with least crimes of all is in May except for one strange fact. More dog bites are reported in this month than in any other month of the year.
Clearly our seasonal cycles of knowledge are completely different from our tendencies for crimes. Professor Huntington made extensive studies to discover the seasons when people read serious books, attend scientific meetings and get highest results on examinations. In all cases, he found a spring high and autumn high separated by a summer low.
Possibly, high temperature and high humidity(湿度)cause our strange and violent summer actions, but police officials are not sure. "There is, of course, no proof of a connection between humidity and murder," they say," Why murder's high time should come in the summer time we really don't know."
A good title of the passage would be ______.
A．Crime Cycles
B．Summer Crimes
C．A Time for Murder
D．The Most Peaceful Month

In New York, Boston and other cities, homelessness is at record levels, a consequence of a faltering (摇晃的) economy that has crumbled even further after the Sept. 11 attacks.
A survey by the U.S. Conference of Mayors released last week found that requests for emergency shelter in 27 cities had increased an average of 13 percent over last year. The report said the increases were 26 percent in Trenton; 25 percent in Kansas City, Mo; 22 percent in Chicago; 20 percent in Denver; and 20 percent in New Orleans.
An unusual confluence of factors seems to be responsible for the surge. Housing prices, which soared in the expansion of the 1990's, have not gone down, even though the economy has tumbled. A stream of layoffs has newly unemployed people taking low-wage jobs that might have otherwise gone to the poor. Benefits for welfare recipients are expiring under government imposed deadlines. And charitable donations to programs that help the disadvantaged are down considerably, officials around the country said, because of the economy and the outpouring of donations for people affected by Sept. 11.
"This is an unprecedented convergence (集中) of calamities (灾难)," said Xavier De Souza Briggs, an assistant professor of public policy at the John F. Kennedy School of Government at Harvard. "It's really a crisis."
More than half the cities surveyed by the mayors' group reported that in the last year people had remained homeless longer, an average of six months.
There is no total number for the homeless nationwide. Experts said it was difficult to compare the situ- ation with statistics in previous decades, because counting methods have improved. Yet, several experts said they believed that the increases reported by cities like Boston and Chicago reflected a national trend.
"My impression is that there is more homelessness now than there was 20 years ago." Gary Burtless, an economist at the Brookings Institution, said, adding that he believed that economic factors were not the sole explanation.
"I think that there must be a greater segment of our population that has tenuous connections to family and friends, and therefore has fewer resources to fall back on when something very bad happens like when they lose their job." he said.
Which of the following is NOT a reason for the increase of homelessness？
A．Unemployment.
B．Housing prices.
C．Sept. 11 attacks.
D．Floods.

Pain is something that everyone experiences at some time, to a greater of lesser degree(在或大或小的程度)
Chronic or long-term pain, however, is in a category(种类，范畴)of its own. This is the kind of pain that dominates and pervades(蔓延，渗透)the life of the sufferer. Relent- less(持续的), grinding, exhausting pain, from which there is no escape(无法逃避的).
Most individuals who experience this kind of pain are paraplegics(截瘫患者)and tetrap1egics(四肢麻痹患者). These people, despite their disabilities, would often be capable of leading fulfilled and happy lives were it not for the fact(要不是/如果没有这一事实) that they suffer this terrible and debilitating(使衰弱)pain on an almost continuous basis.
To date(到目前为止), treatment has been mainly in the form. of heavy drug therapy, which produces unpleasant side effects.
But there has been a breakthrough in pain control. A new device, SPES(Sub Perception Electro Stimulation) (不知觉电刺激), should radically (根本地) improve quality of life for many chronic pain sufferers.
Professor I for Cape l, scientist and inventor, has conducted clinical trials of SPES on chronic pain sufferers with extremely encouraging results.
SPES works by transmitting electrical signals controlled by microprocessors(微型信息处理机 ), in particular patterns across the brain, using tiny electrodes(电板) attached to the patient's earlobes.
These signals stimulate chemical messages from the hypothalamus(下丘脑), the area of the brain which controls our bodily functions.
As a result, a hormonal release is triggered, which alters the perception of pain. "The pain is still there", says Professor Cape l "but SPES helps you live with(接受某种局面)it. We are using .the body's natural ability to cope with pain."
The treatment is painless and convenient, lasting for about an hour a day. The equipment is portable, so the person using it can move around comfortably.
Other benefits are that it is non-addictive(不成瘾的) and the patient does not build up a tolerance(忍受)to SPES. It can be used at home without medical supervision.
SPES should not, however, be used by pregnant women, epileptics(癫病患者), people who have pacemakers fitted(装上起搏器)and those who are taking certain prescribed drugs.
It is reported that only a part of people experience in their life.
A．Right
B．Wrong
C．Not mentioned

Which Vitamin Boosts Brain Power？
Vitamin E has been touted for its anti-aging and anti-cancer benefits because, as an antioxidant, it counters the destructive action of molecules called free radicals. Now a study has shown vitamin E may also help the memory loss and impaired thinking that occurs in the elderly.
Researchers at the Rush Institute for Healthy Aging in Chicago conducted a three-year study involving nearly 3,000 people older than 65 to investigate the cognitive effects of vitamin E in food and supplements.
By comparing the average scores of four different tests of memory and perception, the researchers were able to track change in cognitive function with age. The participants also completed dietary questionnaires periodically, which enabled the researchers to determine their vitamin E intake.
The study found that the higher the intake of total vitamin E, the less change there was in the people's average test scores each year. And those men and women who consumed the most vitamin E had a 36 percent lower rate of decline in their average test scores than those who consumed the least vitamin E. Other antioxidants, such as vitamin A, carotene and vitamin C, had little effect on the results.
Those who took supplements but got little vitamin E from food appeared to have the same protective benefit from the vitamin as those who consumed high amounts of E in their diets, says Martha Clare Morris, an assistant professor at Rush-Presbyterian-St. Luke's Medical Center. Several clinical trials are underway to compare protection from cognitive decline in people taking a supplement or a placebo, she says. In this study, the majority who took a supplement reported taking 400 IU a day.
Vitamin E is
A．very popular among some people.
B．effective in memory enhancement.
C．very helpful to the elderly actions.
D．destructive in aging and cancers.
