Education is compulsory and free for every child in America. Most children start school by the age of six. They attend eight years of elementary school and four years of high school, The money for free public schools comes from taxes, and every state is responsible for its own educational system. State legislatures set the educational requirement but leave the management of the schools in the hands of the local communities. Most states require their children to go to school until a certain age. This age varies from 16 to 18 years, according to the laws of the individual states. The Federal government contributes funds to the states for additional schools and school services.After graduation from high school, a student can start his higher education in a two-year college or university. The cost of a college education is expensive in private universities, but it is much cheaper in those supported by states and cities. Many students receive scholarships from the schools, the government or private foundations. More than 50 percent of college students work to help pay their college expenses. Where does the money for public schools come from()
In an interview last month, Frank Church, chairman of the Senate committee which is investigating the CIA, issued an oblique but impassioned warning, that the technology of eavesdropping had become so highly developed that Americans might soon be left with "no place to hide". That day may have arrived. Newsweek has learned that the country’s most secret intelligence operation, the National Security Agency, already possesses the computerized equipment to monitor nearly all overseas telephone calls and most domestic and international printed messages.The agency’s devices monitor a great deal of telephone circuits, cable lines and the microwave transmissions that carry an increasing share of both spoken and written communications. Computers are programed to watch for "trigger" words or phrases indicating that a message might interest intelligence analysis, when the trigger is pulled, entire messages are tape-recorded or printed out.That kind of eavesdropping is, however, relatively simple compared with the breakthroughs that lie ahead in the field of snoopery. Already it is technically feasible to "bug" an electric typewriter by picking up its feeble electronic emissions from a remote location and then change them into words. And some scientists believe that it may be possible in the future for remote electronic equipment to intercept and "read" human brain waves.Where such capabilities exist, so too does the potential for abuse. It is the old story of technology rushing forward with some new wonder, before the men who supposedly control the machines have found how to prevent the machines from controlling them. What is the author’ s attitude towards eavesdropping()
Some people ought to defend the workaholic.These people are unjustly accused, abused, and defamed -- often termed sick or morbid or on the border of pathology. About 30% of American business and commerce is carried on the shoulders of workaholics. The ratio might exist in art and science too.Workaholics are the achievers, the excelers. There is a national conspiracy against excellence and undue admiration of commonness and mediocrity. It is as if we are against those who make uncommon sacrifices because they enjoy doing something.Some famous psychologists say that the workaholic has an inferiority complex which leads to overcompensation. This is certainly not the case. Inferiority, or low esteem, describes laziness more accurately than it describes dedication.We do not seem to realize that very little excellence is achieved by living a well-balanced life. Edison, Ford, Einstein, Freud all had single-minded devotion to work whereby they sacrificed many things, including family and friendship. The accusation is made that workaholics bear guilt by not being good parents or spouses. But guilt can exist in the balanced life also. Think how many "normal" people and middle-ages who have never done anything well -- they are going to settle for less than what they could have become. From this passage we know that workaholic is a term referring to those().
