C. Changes of tastes for drinks

D. Reducing cancer risks

E. The plant Camellia sinensis

F. A woman’s opinion of tea

1.________________

Americans are far more knowledgeable about drinks than they were 20 years 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.

2.________________

Tea is available in more places than ever. The Tea Association of the United States reports that from 1990 to 1999, annual sales of the drink grew to $4.6 billion from $1.8 billion. “Green tea is seen by consumers as a ‘functional food’” — delivering health benefits beyond food itself, says Vierhile.

3._______________

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 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent 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.

4.________________

One such antioxidant in green tea is ECGC, a compound 20 times as powerful as vitamin E and 200 times 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.

5.________________

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 coffee 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.

Every fast-food employee knows that the drive-through window is the worst position. The window sticks with constant ice; the roar of engines hurts your ? ; your words are lost in the howling wind.

On a ? ? ? afternoon, everything changed.

Every once in a while, the sub-zero temperatures seal a ? ? ? windows shut. Drivers don’t exactly enjoy having to stand outside in the cold,? ? ? their orders into a speaker box, when they expect to drive through on their heated leather seats. In such cases, most customers tend to show their annoyance to the employees.

This woman was ? ? ? .

“I’ll get the next car’s ? ? ? as well,” she said as she came up to the window to pay. She stood outside, ? ? ? much snow on her hair. Though she was obviously freezing, her bright ? ? ? lit up her face like a fire.

“You can’t ? ? ? their drinks,” I said, confused and tired.

“No, but I’ll buy them,” she said. “Pay it forward and all that.”

Completely puzzled, I charged her as ? ? ? , and when the next customer arrived at the window I explained what had just happened. I watched as his ? ? ?? changed — first angry to be out in the cold, then? ? ? ? at the random act of kindness, and finally, delighted by his? ? ? .

“I suppose I’ll pay for the next order then,” he replied, nodding and waving at the impatient driver ? ? him. He ? ? ? over the cash and received his pre-paid hot drink.

The trend continued. Customers arrived annoyed, only to leave ? ? ? and pleased. Some were shocked to spend much more than they had expected, ? ? ? others ended up receiving their order for less than half the price.

Five vehicles passed, then ten, then twenty. No one refused to pay. Customers stood at my window ?? ? ?? a fist-full of change to buy drinks for a complete stranger. Cars drove off, honking (鸣笛) and ?? ? ?? their thanks.

It only takes one customer, one person, to change the entire ? ? ? of traffic. It only takes one moment, one smile, to warm up even the coldest of days.

The rapid growth of cities worldwide over the next two decades will cause significant risks to people and the global environment, according to analysis.

Researches from Yale and Stanford predict that by 2030 urban areas will expand by 590,000 square miles—nearly the size of Mongolia—to meet the needs of 1.47 billion more people living in urban areas.

“It is likely that these cities are going to be developed in places that are the most biologically diverse,” said Karen Seto, a famous scientist at Yale University. “They are going to be growing and expanding into forests, biological hotspots, savannas(热带稀缺大草原), coastlines—sensitive and vulnerable places.”

Urban areas, they found, have been expanding more rapidly along coasts. “Of all the places for cities to grow, coasts are the most sensitive. People and buildings along the coast are at risk of flooding and other environmental disasters,” said Seto.

The study provides the first estimate of how fast urban areas globally are growing and how fast they may grow in the future. “We know a lot about global patterns of urban population growth, but we know significantly less about how urban areas are changing,” she said. “Changes in land cover associated with urbanization lead to many environmental changes, from habitats loss and agricultural land conversion(转化) to changes in local and regional climate.”

The researchers examined studies that used satellite data to map urban growth and found that from 1970 to 2000 the world’s urban footprint had grown by at least 22,400 square miles—half the size of Ohio.

“This number is numerous, but, in actuality, urban land expansion has been far greater than what our analysis shows because we only looked at the published studies that used satellite data,” said Seto. “We found that 48 of the most populated urban areas have been studied using satellite data, with findings in journals. This means that we’re not tracking the physical expansion of more than half of the world’s largest cities.”

Half of urban land expansion in China is driven by a rising middle class, whereas the size of cities in India and Africa is driven primarily by population growth. “Rising incomes translate into rising demand for bigger homes and more land for urban development, which has a great effect on biodiversity conservations, loss of carbon sinks and energy use.”

1.According to the passage, the most dangerous place for city expansion is the _____.

A．forest            B．desert            C．savannas          D．coastline

2.The underlined word “vulnerable” (in Para. 3) probably means “____”.

A．diverse in plants                        B．beautiful in scenery

C．easily damaged                         D．very productive

3.From Para. 5, we can infer that ____.

A．urbanization is a good way to improve people’s standards of living

B．cities develop very fast and more and more people come to live in cities

C．more and more agricultural farmlands are used to make room for local animals

D．in the past, researchers focused their attention on the expanding urban areas

4.Cities in Africa become bigger and bigger mainly because of their ____.

A．growing population                      B．rising middle class

C．unique living patterns                    D．economic development

AIDS’ Threat to Asia Grows

NEW DELHI----Just a few years ago, Mala was a typical middle-class Indian housewife. She cooked, cleaned and looked after her two small children.

Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive and her mother-in-law took her children away from her, saying they would get the disease. “When friends dropped for a visit, she would introduce me, saying, ‘She is my son’s widow. She has AIDS,’” said Mala. AIDS is now described as “explosive(炸药)” around the world. A study of a hospital in the port city of Durban in South Africa, where the world’s biggest and Africa’s second AIDS conference opened last Sunday, found that almost half the beds in medical wards (病房) were occupied by AIDS patients.

South Africa has one of the world’s fastest growing HIV infections, with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus than Africa, where the disease has killed about 12 million people.

AIDS is now threatening to surround many of Asia’s poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of infected people, because of the population base.

In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 860,000 people (the actual number may be a little larger), mainly drug users, live with HIV/AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates that the number hit by AIDS in Asia will climb about eight million over the next five years from about six million.

In many Asian countries, the battle against HIV is a social and cultural one against public discussion of sexual health put a nationwide media campaign into action to limit the speed of HIV through unsafe sex. Brenton Wong, an official for Singapore’s Action for AIDS, says the actual HIV incidence in the city state of 3.9 million people is at least eight times higher than official data. “Shame and deny is still very, very common so people are afraid to get tested and many times won’t even tell their families if they test positive,” said Wong.

We can conclude from the underlined sentence in the last paragraph that ______.

       A. The official data always tell lies and cheat people to hide the truth.       

       B. 3.9 million people in Singapore suffered from AIDS.        

       C. Singapore has a population of 3.9 million    

       D. The number of people infected with HIV is at least eight times larger than that of the AIDS patients in Singapore.

It is judged that there are ______ people hit by AIDS in Asia or so.

       A. 4.3 million      B. 6 million         C. 8 million         D. 3.7 million

According to the passage, the main reasons that AIDS spread in Asia is through_______. 

       A. blood       B. unsafe sex       C. love         D. drugs

Which of the following statements is not right?     

       A. The battle against Aids in many Asian countries is against their culture and

social customs. 

       B. Though the HIV infection in Asia develops with low speed, the infected number

is still quite large compared to other continents.      

       C. India has the second largest number of HIV infected people.  

       D. Aids might affect the poverty-stricken countries more severely.
