A nerve-zapping(电击神经) headset caused people to get rid of fat in a small preliminary study. Six people who had received the stimulation(刺激) lost on average about 8 percent of the fat on their trunks in four months, scientists reported at the annual meeting of the Society for Neuroscience.

The headset stimulated the vestibular nerve(前庭神经), which runs just behind the ears. That nerve sends signals to the hypothalamus, a brain structure thought to control the bodys fat storage. By stimulating the nerve with an electrical current, the technique shifts the body away from storing fat toward burning it.

Six overweight and obese people received the treatment, consisting of up to four one-hour-long sessions of stimulation a week. Because it activated the vestibular system, the stimulation created the sensation of gently rocking on a boat or floating in a pool, said the study’s co-author Jason McKeown of the University of California, San Diego.

After four months, body scans measured the trunk fat for the six people receiving the treatment and three people who received unreal stimulation. All six in the treatment group lost some trunk fat, despite not having changed their activity or diet. In contrast, those in the unreal group gained some fat. Researchers suspect that changes in the set of life-sustaining chemical transformations within human cells are behind the difference. "The results were a lot better than we thought they’d be," McKeown said.

Earlier studies found that vestibular nerve stimulation causes mice to drop fat and pack on muscle, resulting in what McKeown called Schwarzenegger mice. Though small, the current study suggests that the approach has promise in people. McKeown and his colleagues have started a company based on the technology and plan to test it further.

【题目】B

There is something very wrong with the system of values in a society that has only unkind terms like nerd and geek for the intellectually curious and academically serious.

We all know what a nerd is: someone who wears thick glasses and ugly clothes; someone who knows all the answers to the chemistry or math homework but can never get a date on a Saturday night. And a geek, according to Webster’s New World Dictionary, is a street performer who shocks the public by biting off heads of live chickens. It is an obvious fact about our language and our culture that someone devoted to the pursuit (追求) of knowledge is compared to such a strange person.

Even at a famous educational institution like Harvard, anti-intellectualism is widespread: Many students are ashamed to admit how much they study. The same thing happens in US primary and high schools.

Enough is enough. The anti-intellectual values that have spread throughout American society must be fought. There are very few countries in the world where anti-intellectualism runs as high in popular culture as it does in the US. In most industrialized nations, especially in East Asia, a kid who studies hard is praised. But in America, average professional ballplayers are much more respected and better paid than professors of the best universities.

How can a country where typical parents are ashamed of their children studying mathematics instead of going dancing be expected to compete in the technology race with Japan? How long can America remain a world-class power if we constantly put social skills and physical strength over academic achievement and intellectual ability?

Do we really expect to take the lead largely by bringing in our scientists and intellectuals from abroad, as we have done for a major portion of this century without making an effort to also cultivate (培养) a pro-intellectual culture at home?

【1】The definition from the Webster’s New World Dictionary is quoted to __________.

A. show that vocabulary use is always up-to-date

B. prove that words used in this article are accurate

D. show that people look down upon those studying hard

【2】What can be learned from Paragraph 3 and Paragraph 4?

A. The US government doesn’t mean to spend much money on education.

B. Anti-intellectualism is not popular in industrialized countries in East Asia.

C. Few students work hard for their grade in famous universities like Harvard.

D. Professors earn more than professional basketball players on average in the US.

【3】 What is probably the author’s attitude towards the anti-intellectual values?

A. Skeptical. B. Supportive. C. Concerned. D. Objective.

【4】 What can be a suitable title for the text?

A. America needs its nerds. B. Don’t laugh at nerds.

C. What is anti-intellectualism? D. Why does society avoid nerds?
