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

听力原文:Crime has its own cycles,a magazine reported some years ago. Police records show

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.

Although we Americans in recent decades have grown richer, our children have grown poorer.
Many families no longer adequately perform. the nurturing and supporting function that children need, emotionally and intellectually.

The evil consequences for children are not in dispute. The rate of suicide among children aged ten to fourteen is twice as high as it was twenty years ago. For children aged fifteen to nineteen, the rate has tripled.

Since 1983, crimes by children have been rising at a faster rate than the juvenile population. About half of such crimes involve the traditional youthful offenses of theft, breaking and entering, and vandalism, but serious, violent crimes, though still involving a relatively small proportion of children, are going up at a startling rate, The rate of armed robbery, rape, and murder by juveniles has doubled in a decade.

The Senate Juvenile Delinquency Subcommittee surveyed 750 school districts and reported the following changes between 1990 and 1993. Dropouts increased by 11 percent. Drug and alcohol offenses on school property were up 37 percent. Burglaries of school buildings were up 11 percent and assaults on teachers up 77 percent.

Among those who are thought of as "normal" children, lower reading scores and scholastic aptitude scores reveal intellectual impoverishment. Beyond all this loom the apathy and waste of the counterculture. Its existence is no longer news, but its ranks are still swelled each year by thousands of pathetic runaways and, dropouts.

What forces are producing the increasingly severe stresses on today's children?

The phenomenon is complex and baffling, but several developments seem to be interacting. Urbanization is a factor. Children who might have made it on a farm or in a village, despite adverse family circumstances such as extreme poverty or a father's desertion, encounter disaster in a big city with its anonymity and diverse temptations.

Births by unwed mothers and divorce, two trends that are both rising steadily, result in depriving children of the stable, two parent support that they need in their growing years. One out of every six children under eighteen today is living in a single-parent family. This is almost double the proportion in 1950.

Many divorced or widowed parents obviously succeed with their children, but ideally, rearing a child is a two-person job. When one parent is missing, the risk of failure increases. Indeed, it is best if a child has grandparents or other supportive relatives on the scene as well. Instead, what has happened is the near disappearance of the extended family and the substitution of television, the hopelessly inadequate electronic baby-sitter.

One study, for example, revealed that fifty years ago half of the households in Massachusetts included at least one adult besides the parents. Today the figure is only 4 percent. In a small child's life, "Captain Kangaroo" is no substitute for a devoted grandmother.

The bad effect of the treatment American children gets today______.

A.are not taken seriously

B.is beginning to be recognized

C.has aroused hot debates

D.is unquestionable

第10题
For one brief moment, after years of fear and loathing, America seemed ready to make peace
with the SAT. When the University of California several years ago threatened to treat the test like a bad batch of cafeteria food and tell applicants not to buy it, the College Board junked the bewildering analogy questions (Warthogs are to pigs as politicians are to what?), created a writing section (including producing an essay), added tougher math questions and more reading analysis --and had everybody talking about the new-and improved SAT.

Then the first students to take SAT: The Sequel were seen stumbling out of the testing centers as if they had just run a marathon, and all the happy talks ended. With the three hours and 45 minutes stretching to five hours with breaks and instructions, it got worse. Nobody is sure how, but moisture in some SAT answer sheets caused pencil marks to bleed or fade, producing more than 5,000 tests with the wrong scores. Even after that was fixed, several universities reported a sharp drop in their applicants' average scores, which many attributed to exhaustion, and more colleges told applicants they would no longer have to take the SAT.

All of which stoked interest in the ACT, the SAT's less famous and less feared rival based in Iowa City, Iowa. The shorter test is now becoming a welcome alternative for many high schoolers who no longer see a need to endure the usual SAT trauma. "I think the ACT is a true player in the college-admissions game these days," says Robyn Lady, until recently a college counselor at Thomas Jefferson High School for Science and Technology. Although most Jefferson students still take the SAT, the number of ACTs there has tripled in the last two years. It's a shift that, if it continues, could change the balance of entrance test power, since the Fairfax County, Va. , magnet sends more kids to the fry League than almost any other U.S. school.

The SAT, with a maximum 2,400 points, and the ACT, with a maximum 36 points, are scored differently, but otherwise are no more different from each other than American football differs from the Canadian version. Students usually do equally well on each. The SAT's new 25 minute essay is required, while the ACT's essay is optional. The SAT is three hours and 45 minutes long. The comparable ACT is three hours and 25 minutes. The SAT has three sections: critical reading, math and writing. The ACT has math, science, reading and English sections, plus optional writing. The ACT with the writing test costs $ 43, more than the SAT's $ 41.50, but the ACT is only $ 29 without the writing section.

Several high school guidance counselors say they assume the ACT, with 1.2 million test takers in the class of 2005 compared with 1.5 million for the SAT, will eventually catch up, in part because so many educators are advising their students to try both. Wendy Andreen, counselor at Memorial Senior High School in Houston--where the SAT has been supreme--says she tells students every year they should take both tests to be safe, and many are beginning to listen, with ACTs up 18 percent since 2002. Deb Shaver, director of admissions at Smith College, says counselors are steering students to the ACT "because there is less hysteria surrounding the ACTs, and students feel less stressed about taking the test."

The mistakes made in the scoring of the October 2005 SAT by Pearson Educational Measurement, the College Board's subcontractor, have no; been forgotten, counselors say. The SAT suffered from damaging news stories as details of the errors came out bit by bit. In the end, 4,411 students had scores reported to colleges that were lower than they actually earned and had to be corrected; 17 percent of the corrections were for more than 40 points. College Board president Caston Caperton apologized, saying the mishap "brings humility, and humility makes us more aware, empathetic and respectful of others."

But ma

A.the SAT is undesirable.

B.the SAT should be replaced.

C.the SAT's keepers are blamed.

D.the SAT's critics are praised.
