Why Buy Shade-Grown Coffee?
When people argue about whether coffee is good for health,they're usually thinking of the health of the coffee drinker. Is it good for your heart?Does it increase blood pressure?Does it help you concentrate?However,coffee affects the health of the human population in other ways,too.
Traditionally,coffee bushes were planted under the canopy(树冠)of taller indigenous(土生土长的) trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees.At first,this increases production because more coffee bushes can be plan-ted if there aren't any trees.With increased production come increased profits.
Unfortunately,deforesting for coffee production immediately decreases local wildlife habitat. Native birds nest and hide from predators(捕食者)in the tall trees and migrating birds rest there.
Furthermore,in the long term,the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee.The fertilizers and pesti-cides kill insects that eat coffee plant,but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well,and can even enter the water that people will eventually drink.
Fortunately,farmers in Central and South America are beginning to grow more coffee bushes in the shade.We can support these farmers by buying coffee with such labels as“shade grown”and“bird friendly.”Sure,these varieties might cost a little more.But we're paying for the health of the birds,the land,ourselves,and the planet. I think it's worth it.
The function of the word“Traditionally”in Paragraph 2 is to show__________.
A.the positive effects of coffee
B.a change of coffee growth
C.something that is the most important
D.how coffee production used to be

[单项选择] Massive changes in all of the world’s deeply cherished sporting habits are underway. Whether it’s one of London’s parks full of people playing Softball, and Russians taking up rugby, or the Superbowl rivaling the British Football Cup Final as a televised spectator event in Britain, the patterns of players and spectators are changing beyond recognition. We are witnessing a globalization of our sporting culture.
That annual bicycle race, the Tour de France, much loved by the French is a good case in point. Just a few years back it was a strictly continental affair with France, Belgium and Holland, Spain and Italy taking part. But in recent years it has been dominated by Colombian mountain climbers, and American and Irish riders.
The people who really matter welcome the shift toward globalization. Peugeot, Michelin and Panasonic are multi-national corporations that want worldwide returns for the millions they invest in teams. So it does them literally a world of good to see
A. they become more professional than ever.
B. they regard sports as consumer goods.
C. there exist few world-class championships.
