单选题Play Play is the principal business of childhood, and 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 materials for play, and the main tools of play are toys. Their main function 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 profit from the right play materials should not be underestimated. A. baby who is encouraged and stimulated, talked to and shown things and played with, has the best chance of growing up successfully. In 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(七巧板)and construction toys; painting, scribbling(涂鸦) 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. Bt the third stage of play development-from five to seven or eight years-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 chills 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, they lead on to new hobbies, but their significance has changed-to a child of nice or ten years, toys and games mean, as to adults, relaxation and fun.

单选题The Cherokee Nation Long before the white man came to America, the land belonged to the American Indian nations. The nation of the Cherokees lived in what is now the southeastern part of the United States. After the white man came, the Cherokees copied many of their ways. One Cherokee named Sequoyah saw how important reading and writing was to the white man. He decided to invent a way to write down the spoken Cherokee language. He began by making word pictures. For each word he drew a picture. But that proved impossible—there were just too many words. Then he took the 85 sounds that made up the language. Using his own imagination and an English spelling book, Sequoyah invented a sign for each sound. His alphabet proved amazingly easy to learn. Before long, many Cherokees knew how to read and write in their own language. By 1828, they were even printing their own newspaper. In 1830,the US Congress passed a law. It allowed the government to remove Indians from their lands. The Cherokees refused to go. They had lived on their lands for centuries. It belonged to them. Why should they go to a strange land far beyond the Mississippi River? The army was sent to drive the Cherokees out. Soldiers surrounded their villages and marched them at gunpoint into the western territory. The sick, the old and the small children went in carts, along with their belongings. The rest of the people marched on foot or rode on horseback. It was November, yet many of them still wore their summer clothes. Cold and hungry, the Cherokees were quickly exhausted by the hardships of the journey. Many dropped dead and were buried by the roadside. When the last group arrived in their new home in March 1839, more than 4,000 had died. It was indeed a march of death.

单选题Medical Education In 18th-century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Parisand Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King's College (now Columbia University), the first institution in the colonies to give the degree of doctor of medicine. Following the American Revolution, the Columbia medical faculty (formerly of King's College) was combined with the College of Physicians and Surgeons, chartered in 1809, which survives as a division of Columbia University. In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary (私营的) schools of medicine run for personal profit, most of which had 10W standards and poor facilities. In 1910 Abraham Flexner, the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools. Subsequently, the American Medical Association (AMA) and the Association of American Medical Colleges (AAMC) laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals and licensing of medical practitioners (开业医师) that survive to this day. By the late 1980s the US and Canada had 142 4-year medical colleges recognized by the Liaison (联络) Committee on Medical Education to offer the M. D. degree; during the 1987-88 academic year, 47,262 men and 25,686 women entered these colleges and an estimated 11,752 men and 5,958 women were graduated. Graduates, after a year of internship (实习期) , receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners.

单选题{{B}}第三篇{{/B}} Ancient Egypt Brought down by Famine Even ancient Egypt's mighty pyramid (金字塔) builders were powerless in the face of the famine (饥荒)that helped bring down their civilization around 2180 B．C.. Now evidence collected from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today. The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons (季风) southwards out of Ethiopia would have reduced these floods. Declining rains in the Ethiopian highlands would have meant fewer plants to stabilize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment (沉积) from the White Nile. Blue Nile mud has a different isotope (同位素) signature from that of the white Nile, so by analyzing isotope differences in mud deposited in the Nile Delta Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4500 to 4200 years ago, immediately came before the fall of the Egypt's old Kingdom. The weakened waters would have been disaster for the Egyptians. " Changes that affect food supply don't have to be very large to have a ripple (波浪) effect in societies. " says Bill Ryan of the Lamont Doherty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a scientist from the Smithsonian Institution in Washington D.C.. "Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. "
