[单项选择]If anyone knew how to get the best medical treatment, it was Betsy Lehman. A health columnist who had worked at the Boston Globe since 1982, she had covered everything from leading-edge research to the finer points of a physician’s bedside manner. When she learned she had an advanced case of breast cancer, she carefully studied her options and chose to undergo an experimental treatment offered at the Dana-Farber Cancer Institute, a prestigious hospital affiliated with Harvard Medical School. Tragically, the 39- year-old mother of two died in December. Her death was not the result of her disease but of a huge overdose of a powerful anticancer drug accidentally administered by the hospital’s staff.
Lehman’s case is just one of a spate of medical foul-ups that have made headlines in the U.S. in recent weeks. Though no statistical evidence shows that malpractice is on the rise, state licensing boards have stepped up their investigations of doctors. The number of physicians who have

[单项选择]

Although the United States cherishes the tradition that it is a nation of small towns and wide open spaces, only one in every eight Americans now lives on a farm. The recent population trend has been a double one, toward both urbanization and suburbanization. Metropolitan areas had grown explosively in the past decade, and nearly half this increase has been in the suburbs. With the rapid growth of cities has come equally rapid decentralization. The flight of Americans from the central city to the suburbs constituted one of the greatest migrations of modern times; quiet residential sections outside cities have become conglomerations (密集) of streets, split-level houses, and shopping centers.
This spurt of suburban expansion, however, does not alter tile basic fact that the United States has become one of the most urban nations on the face of the earth. Census (人口调查) Bureau figures show that the rural population has been shrinking steadily since 1830. When the United States
A. quiet and residential
B. very rural in character

[不定项选择题]共用题干 Riches and Romance From France's Wine Harvest

September is harvest time. And with bunches of grapes swinging(摇摆)in the wind,
the vineyards of southern France are getting ready to celebrate it.
The yearly wine festival is held in honour of Bacchus,the Roman god of wine.It's a
fun time with parties,music,dancing,big meals and,of course,lots of wine.
French wine-making began more than 2,500 years ago.The world's oldest type of vine
grows in France and always produces a good quality wine.Today France produces one-fifth
of the world's wine,and some of the most famous varieties.
The top wine-producing areas are Bordeaux,Burgundy and the Loire Valley.
Champagne,a drink used in celebrations,is named after the place where sparkling(有气
泡的)wine was first produced in 1700.
Wine is made from the juice of freshly picked grapes. It is the sugars that turn into
alcohol.
Traditionally,people used to take off their shoes and crush the grapes with their bare
feet to bring out the juice.Nowadays,this practice is usually carried out by machines.
Each wine producing region has its own character,based on its type of grapes and soil.
The taste of wine changes with time.Until 1850,all French champagne was sweet.
Now,both wine and champagne taste slightly bitter.
The drink has always been linked with riches,romance and nobleness.Yet the French
think of it in more ordinary terms.
They believe it makes daily living easier,less hurried and with fewer problems.
"All its links are with times when people are at their best;with relaxation,happiness,
long slow meals and the free flow of ideas,"wrote wine expert Hugh Johnson. Different regions in France produce different types of wine.
