People with bigger brains ftend to score higher on standardized tests of intelligence， according to new study findings.

However， the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend， and people with small heads should not automatically believe they are less intelligent. For instance， Albert Einstein’s brain was “not particularly large”， McDaniel noted. “There’s some relationship between brain size and intelligence on the average， but there’s plenty of room for exceptions，” he said.

Interest in the relationship between brain size and intelligence grew in the1830s，  when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was “an unquestionable connection between the size of the brain and the mental energy displayed by the individual man”. Since that statement， scientists have conducted numerous studies to determine if Tiedmann’s  assertion was， in fact， correct. Most studies have looked into the link between head size and intelligence. More recently， however， researchers have published additional studies on brain size and intelligence， measured using MRI scan(核磁共振成像扫描).

For his study， McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average， people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men， and in adults than in children. McDaniel notes in the journal Intelligence.

McDaniel is not sure why the relationship was stronger for adults and women. “Other research has shown that women， on the average， tend to have smaller brains than men， but score just as well—if not higher—in tests of intelligence，” he said.

McDaniel insisted that the relationship between brain size and intelligence is not a “perfect” one. “One can certainly find lots of examples of smaller-sized people who are highly intelligent，” he said， “But， on the average， the relationship holds.”

Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory. More important, the work provided the first solid induction (归纳) of how alcohol works to protect the heart.

In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection: those who drank alcohol had higher blood levels of high density lipoproteins, the so-called good cholesterol, which is known to prevent heart disease.

As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to recommend a regular happy hour for everyone. The risks of teetotalling (绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behaviour and traffic accidents. Moreover, some studies suggest that even  moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighbourhood bar or liquor store.

The medical article quoted in the first paragraph indicates            .

A. the way in which alcohol can help the heart

B. how a couple of cocktails daily can stop heart problems

C. why alcoholic drinks are dangerous to one’s health 

that reports on the advantages of alcohol were misled

Experiments showed that nondrinkers had __________.

A. larger amounts of good cholesterol             B. smaller amounts of good cholesterol

C. higher blood pressure                             D. lower blood pressure

According to the passage, moderate drinking            .

A. is recommended by most doctors for heart patients

B. should be allowed on prescription

C. is still not medically advisable

D. is not related to liver problems

The main theme of this passage is .

A. the change in recent drinking habits

B. the connection between cancer and alcohol

C. whether moderate drinkers outlive nondrinkers

D. whether alcohol may be good for one’s health
