The True Story of a Young Man

When Reginald Lindsay received a scholarship to Morehouse College in Atlanta, Georgia, what he wanted most was a good job with a good salary. But soon he became interested in the civil rights movement. At present he has a plan which he hopes will take him to Congress as a southern representative.Now in his first year at Harvard Law School, Reg is making careful plans. After earning his degree, he expects to return to the South to practice law among the poor. "I want to help them understand what their rights are and to help them achieve them," he says. Then he hopes to run for political office at the local and state level until he is ready to try for Congress.Reg grew up in a low-income Negro section of Birmingham, Alabama. Brought up by his grandparents after his parents were divorced while he was very young, Reg has been living through a period of far-reaching progress in race relations. In the summer of 1968 Reg himself became a good example of this progress when he became the first Negro student appointed to a special new program. The program introduces bright young students to the workings of the Georgia State government and encourages them to seek employment there after finishing their education. "I've been lucky," he says. "I seem to have been in the right place at the right time."

But luck is only part of Reg's story, for he has made the most of opportunities that came his way. He learned to read in kindergarten and began visiting the public library regularly to borrow books. His grandparents encouraged him, though neither of them had much education, and they bought him a set of encyclopedias. "I loved those books," he re- members. "I used to come downstairs before breakfast and read short articles. I enjoyed reading about famous men, and then I would pretend to be one of them. I guess it was partly a childish game and partly an escape. It wasn't too much fun to be a Negro when I was a kid."

While studying for his bachelor's degree at Morehouse College, Reg worked on several political campaigns helping candidates get elected to government offices. At the same time he maintained a "B" average while majoring in political science. He worked as a student advisor to earn extra money for his college expenses, and he was granted a scholarship for a year of study at the University of Valencia in Spain.With just two more years to complete at Harvard Law School, which also gave him a scholarship, Reg has made a good start on his professional career. He says, "The good life for me is the kind of life where I can find satisfaction in public service."

School buildings themselves can show liberal (开明的) or conservative views about what should go on in a classroom. The earliest schools had separate classrooms for different grades. The rooms were laid out formally, with pupils’desks fastened to the floor in straight rows facing the teacher’s desk. Clearly, such schools reflected a teacher-and-subject-centered view of education. Schools of the next generation had more open space, and most had movable desks. They also often provided special rooms or areas for science, art, music, and physical education. There were still separate rooms for different grade levels, however, and the desks still were likely to be formally arranged. That is, the schoolroom was still largely designed to carry out the old-school program, which involved grade levels, uniform. time blocks, and study of subject matters. Newer subjects, not newer teaching methods, accounted for most of what was new in school design. The first school buildings constructed to encourage liberal teaching methods appeared in the mid-1950s. Folding interior (内部的) walls permitted the flexible use of space to encourage large-group, small-group, or individual instruction. Some provided carrels for individual study, areas for team teaching, and centers for programmed instruction. In the newest buildings called open schools, the use of space is even more flexible. Areas within the buildings can be readily expanded for program changes, and used for many kinds of functions. One should remember, though, the physical layout (布局) of a school cannot decide whether it has the conservative or liberal teaching practices. What determines whether the classroom is liberal or conservative is the spirit and attitude of the teacher. The word “carrel” in Paragraph 3 most probably refers to ________.

A、a room with folding walls

B、a room with liberal instructions

C、a room with conservative instructions

D、a room with small space

ational system in this country.Immigrants(移民) complain,too.Lately a German friend was filled with anger when he learned that the mathematics test given to his son on his first day as a college freshman included multiplication and division.Japanese businessmen in Los Angeles send their children to private schools staffed by teachers imported from Japan to learn mathematics at Japanese levels,generally considered at least a year more advanced than the level here.

But I wonder:If American education is so poor,why is it that this is still the country of innovation. When I was 12 in Indonesia,I had to memorize the names of all the world's major cities,from Kabul to Karachi.At the same age,my son,who was brought up a Californian,thought that Buenos Aires was Spanish for good food.However,unlike children of his age in Asia and Europe,my son had studied creative geography.When he was only 6,he drew a map of the route that he traveled to get to school,including the streets,the traffic signs and the houses that he passed.

Dissatisfied American parents forget that in this country their children are able to experiment freely with ideas; without this they will not really be able to think or to believe in themselves.

Critics of American education cannot grasp one thing:freedom.America,I think,is the only country that extends even to children the license to freely speak,write and be creative.Our public education certainly is not perfect, but it is a great deal better than any other.I think I have found the answer to my question.

截取一段明文如下:

The Mutual Information Analysis (MIA) is a generic side channel distingui she that has been introduced at CHES 2008. This paper brings three contributions with respect to its applicability to practice. First, we emphasize that the MIA principle can be seen as a toolbox in which different (more or less effective) statistical methods can be plugged in. Doing this, we introduce interesting altematives to the original proposal. Second, we discuss the contexts in which the MIA can lead to successful key recoveries with lower data complexity than classical attacks such as, eg. using Pearson's correlation coefficient. We show that such contexts exist in practically meaningful situations and analyze them statistically. Finally, we study the connections and differences between the MIA and a framework for the analysis of side- channel key recovery published at Eurocrypt 2009. We show that the MIA can be used to compare two leaking devices only if the discrete models used by an adversary to mount an attack perfectly correspond to the physical leakages.

her is insensitive to the cues and signals of the infant, whose brain is programmed to mop up(吸收) language rapidly. There are critical times, it seems, when children learn more readily. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.Linguists suggest that speech milestones are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ (Intelligence Quotient(智商. At twelve weeks a baby smiles and utters vowel-like sounds; at twelve months he can speak simple words and under- stand simple commands; at eighteen months he has a vocabulary of thirty to fifty words. At three he knows about 1000 words which he can put into sentences, and at four his language differs from that of his parents in style. rather than grammar.Recent evidence suggests that an infant is born with the capacity to speak. What is special about man's brain, compared with that for the monkey, is the complex system which enables a child to connect the sight and feel of, say, a teddy-bear with the sound pattern "teddy-bear". And even more incredible(不可思议) is the young brain's ability to pick out an order in language from the hubbub(喧哗) of sound around him, to analyse, to combine and recombine the parts of a language in novel ways.But speech has to be triggered(触发), and this depends on interaction between the mother and the child, where the mother recognizes the cues and signals in the child's babbling, (咿咿呀呀) clinging, grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's non-verbal cues is essential to the growth and development of language.
