听力原文: Catherine Gram graduated from the University of Chicago in 1938 and got a job as a news reporter in San Francisco. Catherine's father used to be a successful investment banker. In 1933, he bought a failing newspaper, The Washington Post.
Then Catherine returned to Washington and got a job, editing letters in her father's newspaper. She married Philip Gram, who took over his father-in-law's position shortly after and became a publisher of The Washington Post. But for many years, her husband suffered from mental illness and he killed himself in 1963. After her husband's death, Catherine operated the newspaper. In the 1970s, the newspaper became famous around the world and Catherine was also recognized as an important leader in newspaper publishing. She was the first woman to head a major American publishing company, the Washington Post company. In a few years, she successfully expanded the company to include newspaper, magazine, broadcast and cable companies.
She died of head injuries after a fall when she was 84. More than 3 thousand people attended her funeral, including many government and business leaders. Her friends said she would be remembered as a woman who had an important influence on events in the United States and the world. Catherine once wrote, "The world without newspapers would not be the same kind of world."

Translate into Chinese. 1.Dense WDM however is another thing. Dense WDM refers to the close spacing of channels. Sadly, "dense" is a qualitative measure and just what dense means is largely in the mind of a particular individual. To some, a series of WDM channels spaced at 3.6 nm apart qualifies for the description. Others use the term to distinguish systems where the wavelength spacing is1nm per channel or less. 2.In 1998 the "happening” Wavelength Division area in optical communications was Multiplexing (WDM). This is the ability to send many (perhaps up to 1000) independent optical channels on a single fiber. 3.If a short pulse of light from a source such as a laser or an LED is sent down a narrow fiber, it will be changed (degraded) by its passage down the fiber. It will emerge (depending on the distance) much weaker, lengthened in time ("smeared our"), and distorted in other ways. 4.In the wide area environment a large coaxial cable system can easily involve a cable of several inches in diameter and weighing many pounds per foot. 5.It is possible to tap fiber optical cable. But it is very difficult to do and the additional loss caused by the tap is relatively easy to detect. There is an interruption to service while the tap is inserted and this can alert operational staff to the situation. In addition, there are fewer access points where an intruder can gain the kind of access to a fiber cable necessary to insert a tap.

In so many ways, Singapore has elevated the concept of efficiency to a kind of national ideology. For the past ten years, Singapore's work force was rated the best in the world--ahead of Japan and the U. S. --in terms of productivity, skill and attitude by the Business Environment Risk Intelligence service.
Behind the "Singapore miracle" is a man Richard Nixon described as one of "the ablest leaders I have met," one who, "in other times and other places, might have attained the world stature of a Churchill. " Lee Kuan Yew led Singapore's struggle for independence in the 1950s, serving as Prime Minister from 1959 until 1990. Today (1995), at 71, he has nominally retired to the office of Senior Minister, where he continues to influence his country's future. Lee offered companies tax breaks, political stability, cheap labor and strike-free environment.
Nearly 90 percent of Singaporean adults now own their own homes and thanks to strict adherence to the principle of merit, personal opportunities abound. "If you've got talent and work hard, you can be anything here," says a Malaysian-born woman who holds a high-level civil-service position.
Lee likes to boast that Singapore has avoided the "moral breakdown" of Western countries. He attributes his nation's success to strong family ties, a reliance on education as the engine of advancement and social philosophy that he claims is superior to America's.
In an interview with Reader's Digest, he said that the United States has "lost its bearings" by emphasizing individual rights at the expense of society. "An ethical society," he said, "is one which matches human rights with responsibilities. "
What characterizes Singapore's advancement is its ______.
A.computer monitoring
B.work efficiency
C.high productivity
D.value on ethics
A.domestic
B.classical
C.existence
D.feature
