Passage Two

Questions 26 to 30 are based on the following passage.

We all know that humans are damaging the environment, but what can we do about it? Some people are trying to do their bit to be more environmentally friendly.

Local councils in Britain encourage certain aspects of green living, such as recycling paper, tin, plastic and glass. They want to reduce the amount of rubbish going into landfill sites（填埋场），because they are running out of places to dump（倾倒）rubbish. In some areas rubbish for recycling is collected from your doorstep, but in other areas, you have to take it to a special recycling place, such as a bottle bank.

Another way of reducing the amount of rubbish you create is to use reusable products instead of disposable ones For example, some people use strong shopping bags or boxes for their groceries instead of plastic carrier bags, or use washable nappies instead of disposables.

More people are becoming interested in reducing their carbon footprint—the amount of carbon they use up. They try to reduce their carbon emissions（释放）by cycling, using public transport or an electric car, rather than driving gas-consuming vehicles. Some people choose not to fly for holiday trips because planes are the biggest producers of carbon emissions.

You can make‘green’ choices when buying food too. It's best to buy food which was locally grown or produced so that it hasn't been imported by air, or shipped by road from far away.

Houses can be environmentally friendly too. It takes less energy to heat a house if it has good insulation（绝缘，隔热）and double glazing (双层玻璃）．You can also create your own energy it you have solar panels or a wind turbine fitted though these can be expensive. You can also save water by using a rain water container for washing the car or watering the garden. It's even possible to use a system where‘grey water’—water which has been through a tap（水龙头）once already, is used to flush（冲洗）toilets. Some new housing projects are being built specifically to be as environmentally friendly as possible.

26．The purpose of collecting reusable wastes is to＿．

A．save energy consumed in daily life

B．reduce the amount of rubbish dumped

C．create a new way of green living

D．decrease the amount of carbon produced

Americans are far more sophisticated about beverages than they were 20 years ago. Witness the Starbucks revolution and you'll know where the trend goes. Now, spurred on by recent studied suggesting that it can cut the risk of cancer and heart disease and retard the aging process, tea is enjoying a similar jolt. Enough chic tea salons are springing up to make even diehard coffee drinkers consider switching beverages.

Tea is available in more places than ever. "Tea was one of the most prolific beverage categories in 1999," with 24 percent more products offered over the previous year, reports Tom Vierhile of Marketing Intelligence Service, which tracks food and beverage trends. And 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 sustenance," says Vierhile.

Recently published studies point out that not all brews are created equal. Only teas that come from the leaves of the plant Camellia sinensis — which, in their raw state are brewed to make green tea, and, with curing, can be turned into oolong and black tea leaves — have been shown to contain health benefits. Other herbal teas and infusions 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 in these so-called real teas can also prevent cancer.

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 cheep they can do to reduce their cancer risk, I tell them drink real tea." Says Mitchell Gaynor, director of medical oncology at New York City's Strang-Cornell Cancer Prevention Centre.

Among those inspired to become a green-tea drinker is Tess Ghilaga. A new York Writer who took it up after consulting 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 properties." Now Ghilaga and her husband routinely brew tea they order theirs from Inpursuitoftea.com, an internet tea company, which sells a variety of ready-made and raw teas. http://www. alitea.com/ — along with green, black, and oolong tea, this company sells a wide variety of herbal teas and offers a "Tea of the Month" club. http://www. Teasofgreen.com/ — this site sells higher-end green, black and oolong teas and has good tips on proper storage and preparation of tea. http://www. tea.com/ — tea drinkers can find links to sites offering tea lore, such as articles about tea ceremonies in foreign lands. An exhaustive "frequently asked question" file found out the site.

What do recent studies reveal about tea drinking?

A．Many tea houses have sprung up to meet the market demands.

B．Drinking tea can cut the risk of lung cancer in particular.

C．Tea is rather a magical drinking material to slow down the aging process.

D．Many die-hard coffee brewers have developed strong sentiments towards tea.
