3.John Hewitt studies the biology of intelligence.He's also a parent.Over the years,Hewitt has drawn on his scientific knowledge in making parenting decisions."I'm a father of four children myself.I never worried too much about the environments that I was providing for my children,because I thought it would all work out in the end anyway-aren't the genes especially powerful?"Hewitt says.He knew intelligence has a strong biological part.If your parents are smart,you'll probably be smart.
But recently,Hewitt discovered something that surprised him."Well,I may have been wrong,"he admits."It is the environmental increase you can get,or the harm you can suffer through hard times that may be a little more important in adolescence than I had thought."
Hewitt and other researchers recently noticed that kids who had a higher IQ to begin with seemed to have an extended period in adolescence during which they kept the ability to learn at a rapid pace,just like much younger children.
"It was as if there was an extended sensitive period in the higher IQ individuals.Or another way of looking at it is that the sensitivity to the environment which is characteristic of earlier childhood seems to end earlier for individuals with a lower IQ,"Hewitt says.Smart kids may tend to take part in challenging activities and this keeps them receptive to learning.Or it could be that genes that lead to a high IQ also cause an extended learning period.
An extended learning period does not necessarily mean a further increase in the IQ.But a very smart teenager with an extended"sensitive period"of learning might be able to pick up a new language or a musical instrument.Such learning can have long?term benefits.
"Even if in the end the IQ ends up being determined to a large extent by the genes,if there's been a period where the environment makes a difference,that could have lifelong consequences,"Hewitt says.

| A.The spreading tea B.The history of tea growing C.Changes of tastes for drinks D.Reducing cancer risks E.The plant Camellia sinensis F.A woman's opinion of tea |
Americans are far more knowledgeable about drinks than they were 20years ago.Witness the Starbucks revolution and you'll know where the trend goes.Now,encouraged by recent studies suggesting that it can cut the risk of cancer and heart disease and slow the aging process,tea is enjoying a similar change.Enough fashionable tea houses are springing up to make even longtime coffee drinkers consider switching drinks.
62.A
Tea is available in more places than ever.The Tea Associa-tion of the United States reports that from 1990to 1999,annual sales of the drink grew to 4.6billionfrom 1.8billion."Green tea is seen by consumers as a'functional food'"-delivering health benefits beyond food itself,says Vierhile.
63.E
Recently published studies point out that only teas that come from the leaves of the plant Camellia sinensis have been shown to contain health benefits.Other herbal teas may taste good,yet they do little more than warm up the drinker.But for Camellia sinensis,the evidence is powerful.In a 1998study,Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44percent compared with non-tea drinkers,and other studies have suggested that the antioxidants(抗氧化剂)in these so-called real teas can also prevent cancer.
64.D
One such antioxidant in green tea is ECGC,a compound 20times as powerful as vitamin E and 200times as powerful as vitamin C."When people ask me for something good and cheap they can do to reduce their cancer risk,I tell them to drink real tea,"says Mitchell Gaynor,director of medical oncology at New York City's Strang-Cornell Cancer Prevention Center.
65.F
Among those inspired to become a green-tea drinker is Tess Ghilaga,a New York writer who took it up after seeking advice from a nutritionist six years ago."I've never been a cof-fee drinker,"says Ghilaga,33."She told me to start drinking green tea for the antioxidant qualities."Now Ghilaga and her husband habitually make tea-they order theirs from Inpursuitoftea.Com,an Internet tea company.And although tea contains about half the amount of caffeine in a cup of coffee,"you still get such a kick from it,"says Ghilaga.
