Elderly adults who regularly drink green tea may stay more active and independent than their peers over time,according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals that may help ward off the cell damage that can lead to disease.Researchers have been studying green tea's effect on everything from cholesterol(胆固醇)to the risk of certain cancers,with mixed results so far.
For the new Japanese study,researchers decided to examine the question of whether green tea drinkers have a lower risk of frailty and disability as they grow older.
Tomata and his colleagues followed nearly 14,000 adults aged 65 or older for three years.
They found those who drank the most green tea were the least likely to develop “functional disability”,or problems with daily activities or basic needs,such as dressing or bathing.
Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups fl day.
The study did not prove that green tea alone kept people active as they grew older.
Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education.lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness.
They also tended to be more socially active and have more friends and family to rely on.
Although it's not clear how green tea might offer a buffer(缓冲剂)against disability,Tomata's team did note that one recent study found green tea extracts(提炼物)seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could block drugs that prevent blood thickened.
Which of the following can summarize the passage best?

A.Green tea makes you less active.
B.Green tea makes you less disabled.
C.Green tea makes you more friendly.
D.Green tea makes you more educated.

The underlined word“ward off”in Paragraph 2 probably means     .

A.form B.absorb C.remove D.prevent

Tomata and his colleagues wanted to     .

A.prove whether the Japanese study is correct
B.know if green tea drinkers are independent
C.help nearly 14,000 adults aged 65 or older
D.study green tea's effect on cholesterol

Which of the following is NOT the advantage of green tea?

A.Reduce functional disability.
B.Keep old people active.
C.Make more friends.
D.Suffer fewer heart attacks.

It can be inferred from the last paragraph     .

A.green tea is safe to drink
B.green tea should be drunk properly
C.green tea is poisonous for old people
D.vitamin K is helpful to us

I came to study in the United States a year ago .Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.
After the accident .my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I’d have to have a good lawyer. And only a good doctor can help me get a good lawyer .Now that he had helped me find a good doctor, it was only fair that I should pay him.
But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report was made up of ten lines, and it cost me $215.
My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss(解雇) him. And he made me pay him $770.
Now I had to act as my own lawyer. Due to my inexperience, I told the insurance company(保险公司) the date I was leaving America. Knowing that, they played for time…and I left without getting a cent.

What will man be like in the future—in 5000 or even 50, 000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago , was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’ s capacity(容量). As time goes on , however , we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact , we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’ s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however , our fingers will grow more sensitive(敏感的) because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. …
The passage mainly tells us that _______.

A.man’s life will be different in the future.
B.future man will look quite different from us.
C.man is growing taller and uglier as time passes.
D.human’s organs’ functions will become weak “

The change in man’s size of forehead will probably be because ___________.

A.he makes use onIy20% of the brain’s capacity.
B.his brain has grown larger over the past centuries.
C.the other 80% of his brain will grow in due time
D.he will use his brain more and more as time goes on :

What will be true about a human being in the future?

A.He will be hairless because hair is no longer useful.
B.He will have smaller eyes and will wear better glasses.
C.His fingers will grow weaker because he won’t have to make use of them.
D.He will think and feel in a different way.

It is implied that ________.

A.human beings will become less attractive in the future
B.less use of a bodily organ may lead to its degeneration(退化,)
C.human beings hope for a change in the future life
D.future life is always predictable

One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.
Without having a nature experience, kids, can turn out just fine, but they are missing out a huge enrichment of their lives. That contributes to everything from their physical health and mental health, to stress levels, creativity and cognitive (认知的) skills. Experts predict modern kids will have poorer health than their parents---and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component(成份) and that play in nature develop leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child. The three-year-old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.
Kids are not to blame. They are overprotected and frightened. It is dangerous out there from time to time, but much stress from computers is replacing breaking an arm as a childhood process of passage.
Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that strengthen love, respect and need for landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause.
According to the passage, children without experiencing nature will______

A.keep a high sense of wonder
B.be over-protected by their parents
C.be less healthy both physically and mentally
D.change wild places and creatures for the better

According to the author, children’s breaking an arm is_____

A.the fault on the part of their parents
B.the natural experience in their growing up
C.the result of their own carelessness in play
D.the effect of their repetitive stress from computers

A.blame children for getting lost in computer games
B.encourage children to protect parks from encroachment
C.show his concern about children’s lack of experience in nature
D.inspire children to keep the sense of wonder about things around

Mike Maietta was eating lunch when he got a text message from his mom.
“Notre Dame,” it said. “Big envelope!”
Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big trouble. So Mike and his parents are considering offers from several other colleges and are figuring out the costs of tuition, housing and holiday trips home.
This year, money is the driving factor(因素) for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and house prices have changed family spending.
“We’re excited that Mike got into eight great schools,” said Mike’s father, an engineer at Microsoft. “But if you consider going to school out of state, you’ve got to think about all of the other costs: moving, flying back and forth for the holidays. You’re looking at about $3,000 a year, just for travel.”
As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased.
Rachel Brown was happy to get a thick envelope from New York University (NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego (UCSD), because of the high cost in New York.
“The tuition for NYU is twice as much as UCSD,” said Rachel, 17. “My mom doesn’t want me to have a big debt when I graduate, and I don’t want that either. I’d have to take out a loan of $15,000. I’ll check and see if there’s any way that NYU can offer me any financial aid.”
More than 7.6 million American students have filled out the Free Application for Students Aid, 19.9 percent increase over last year.
This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000.
Mike may give up Notre Dame because of ______.

A.travel fees
B.financial concerns
C.poor exam results
D.worries about living far away from home

The phrase “Big envelope” in paragraph 2 probably refers to“______”.

A.A text message B.A large gift package

B.Rachel Brown has given up NYU because of its high tuition and big debts.
C.It is inevitably hard for college students to borrow money to cover costs.
D.An interest-free loan for students helps more students apply for Stanford.
