Ques:She was born to wealth and power in a time when money and politics were left to the men. Later, as The Washington Post's publisher, Katharine Graham became one of America's most powerful women. Despite a privileged  background, Katharine had to deal, while growing up, with the high demands her mother placed on her children.Katharine's love of journalism, which she shared with her father, led to her career after college at The Washington Post, the newspaper her father bought in 1933.At the Post, Katharine met Phil Graham, a young, charming lawyer who became her husband.When, in 1945, Katharine's father chose Phil over her to take over his struggling paper, Katharine didn't object and stayed at home as a wife and mother of four. While Phil's successful efforts to restore the Post to fame made the Grahams popular members of the Washington social scene, Katharine privately suffered great pain from her husband's increasingly harmful behavior caused by severe depression.When Phil committed suicide , the 46-year-old Katharine found herself thrown into a new job, that of newspaper publisher.But determined to save the family paper for her children, Katharine rose to the challenge of running the Post, attending meetings in every department, working endlessly to prove herself to her critics, and becoming the toast of Washington. In 1971, Katharine ordered the Post to print a copy of the Pentagon Papers, the top-secret documents telling the truth about the United States' involvement in the Vietnam War.What's more, her courageous decision and support for her journalists prepared the Post to break the most important political story in modem history: Watergate   , one of the greatest scandals   in American political history.Katharine managed to keep control over the most disorganized situation when it was reported, all the time insisting the news stories be accurate and fair.Watergate made the Washington Post an internationally known paper and Katharine was considered as the most powerful woman in America. When her husband was chosen to take charge of the newspaper, Katharine Graham   _  . A) was strongly against the idea B) was not happy to be refused C) was willing to take her share of responsibility D) didn't believe her husband would do a good job

Ques:According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year.Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom.An experiment under way off the coast of Norway, however, could help put them anywhere. The project, called Hywind, is the world's first large-scale deepwater wind turbine  .Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents totally new technology.The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind's creator, the Norwegian company StatoilHydro, has developed recently.The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywind's stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power.If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September. To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it's difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean.To make that turbine heavier, the whole spar's center of gravity must be moved much closer to the ocean's surface.To do that, the company plans to design a new kind of wind turbine, one whose gearbox   sits at sea level rather than behind the blades. Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large.Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted.Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection.If the technology catches on, it will open up vast areas of the planet's... Wide applications of deepwater wind power technology can  _  . A) solve the technical problems of deepwater windmills B) make financial profits by producing more turbines C) settle the arguments about environmental problems D) explore low-carbon power resources available at sea

Ques:Play is the basic business of childhood, and more and more in recent years research has shown the great importance of play in the development of a human being.From earliest infancy  , every child needs opportunity and the right material for play, and the main tools of play are toys.The main function of toys is to suggest, encourage and assist play.To succeed in this, they must be good toys, which children will play with often, and will come back to again and again.Therefore, it is important to choose suitable toys for different stages of a child's development. In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life.So a baby's ability to benefit from the right play materials should not be underestimated.A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully. The next stage, from three to five years old, curiosity knows no bounds.Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws and construction toys; painting, scribbling and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others. By the third stage of play development--from five to seven or eight years old-- the child is at school.But for a few more years play is still the best way of learning, at home or at school.It is easier to see which type of toys the child most enjoys. Until the age of seven or eight, play and work mean much the same to a child.But once reading has been mastered, then books and school become the main source of learning.Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed --to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun. 61. According to the passage, the abilities a child has inherited from his parents   _  . A) determine his character B) will not change after the age of three C) partly determine the standard he is likely to reach D) to a large extent determine the choice of toys
