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.”

______ he referred to in his article was often discussed by many people.

An 18th-century statesman Edmund Burke once said, “All that is needed for the success of a misguided cause is that good people do nothing.” One such cause now seeks to end biomedical research because of the theory that animals have rights to decide whether to be used in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are puzzling the public and threatening advances in health knowledge and care. Leaders of the animal rights movement attack biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing false reports of cruelty to animals in research settings, many are puzzled that anyone would harm an animal on purpose.

For example, a grandmotherly woman setting up an animal rights booth at a recent street fair was giving out sheets that encouraged readers not to use anything that comes from or is tested in animals－no meat, no fur, no medicines. Asked what will happen when epidemics(传染病) return, she said. “Don’t worry, scientists will find some way of using computers.” Such well-meaning people just don’t understand.

Scientists must communicate their message to the public in an understandable way－in human terms, not in the language of biology. We need to make clear the connection between animal research and a grandmother’s organ replacement, a father’s bypass operation, a baby’s vaccinations(接种疫苗), and even a pet’s shots. To those who know nothing about the animal research that was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst.

Much can be done. Scientists could give middle school lessons and present their own research. They should be quick to respond to letters to the editor, in case animal rights misinformation goes unchallenged and gains a false appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because there are a lot of patients, the health research community should actively recruit(招募) not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that uninformed citizens will wipe out the precious of medical progress.

1. The purpose of the author beginning his article with Edmund Burke’s words is to _____.

A．call on scientists to take some actions

B．argue against the cause of animal rights

C．warn of the failure of biomedical research

D．show the success of the animal rights movement

2. In the second paragraph, the author took a grandmotherly woman as an example to show ____.

A. the way to prevent epidemics B. the innocence of the woman

C. how strong the opposition was D. how important the animal rights were

3. In the eyes of the author, misguided people are likely to think that using an animal in research

is ______.

A．cruel but necessary B．just but unnecessary

C．meaningful and wasteful D．inhuman and unacceptable

4. What can be inferred from the passage?

A．People care very little about returns of epidemics.

B．The public lacks knowledge of biomedical science.

C．Stephen Cooper is very seriously concerned about animal treatment.

D．Scientists should make efforts to develop new cures by means of hi-tech.

5. According to the passage, the author’s attitude toward biomedical research is ________.

A. Disinterested B. Indifferent C. Objective D. Supportive

In “Relax, We’ll Be Fine”, columnist David Brooks writes, “the fact is, despite all the problems, America’s future is extremly bright.”

Mr. Brooks acknowledges that “According to recent survey, 60 percent of Americans think the country is heading in the wrong direction. The same percentage believe that the U.S. is in long-term decline. The political system is not functional. A financial crisis looks unavoidable. There are plenty of reasons to be sad.”

But, he writes:

“Demographers(人口学家) predict that over the next 40 years, the U.S. population will increase by an additional 100 million people, to 400 million over all. The population will be determined, hardworking and relatively young. In 2050, only a quarter will be over 60, compared with 31 percent in China and 41 percent in Japan.”

As the rising generation leads an economic recovery, it will also participate in a communal

(of community) one. We are living in a global age of social entrepreneurship(创业精神).

In sum, the U.S. is on the edge of a demographic, economic and social recovery, built on its historic strengths. The U.S. has always been good at destructive change. And it’s always been good at decentralized community-building, too. Surely a country with this much going for it is not going to wait around passively and let a rotten political culture drag it down.

51．In his article Relax, We’ll Be Fine, David Brooks intends to____________.

A．encourage Americans to be optimistic about their future

B．give Americans courage to face their financial crisis

C．persuade Americans to live happily and generously

D．inspire Americans to lead an economic recovery

52．There are all the reasons for Americans to be unhappy except____________

A．the function-failed political system B．the increasing population

C．the declining economy D．the wrong direction and financial crisis

53．Over the next 40 years, according to David Brooks, Americans will be____________

A．more optimistic and humorous B．more pessimistic and stronger

C．more energetic and promising D．more considerate and aggressive

54．In the author’s opinion, America____________.

A．has always benefited from wars B．has done well by its political system

C．has contributed a lot to human progress D．has contributed to world’s economy

55．We can learn from the passage that____________

A．American political system and culture are backward

B．Americans are not a nation to give in to difficulties

C．Americans are very destructive and aggressive

D．America has been in an economic and social recovery
