1.Passage FourAt the 1893 Columbian Exposition,a World Fair held in Chicago,chocolate-making machinerymade in Germany was displayed.It caught the eye of M.S.Hershey,who saw the potential forchocolate.He installed chocolate machinery in his factory in Lancaster,and produced his firstchocolate bars in 1894.Other Americans began mixing in other materials to make up new candy bars throughout the end of the 1890's and the early 1900's.But it was World War l that really brought attention to the candy bar.The U.S.Army Quartermaster Corps requested various American chocolate manufacturers toprovide 20 to 40 pound blocks of chocolate to be shipped to quartermaster bases.The blocks were cut into smaller pieces and distributed to American soldiers in Europe.Eventually the task of making smaller pieces was turned back to the manufacturers.By the end of the war when the soldiers arrived home,the American candy bar business was assured.Why?Because the returning soldiers had grown fond of chocolate candy and wanted more of the same.As a result,from that time on and through the 1920's,candy bar manufacturers became established throughout the United States,and as many as 40,000 different candy bars appeared on the scene.The original candy bar industry had its start on the eastern coast in such cities as Philadelphia,Boston,and New York.The industry soon spread to the Midwest because shipping and raw materials such as sugar,corn syrup,and milk were easily available.Chicago became the seat of the candy bar industry and is even today an important base.51.What is this passage mainly about?

10.It is customary for adults to forget how hard and dull and long school is. The learning by memory of all the basic things one must know is a most incredible and unending effort. Learning to read is probably the most difficult and revolutionary thing that happens to the human brain and if you don’t believe that, watch an illiterate adult try to do it. School is not easy and it is not for the most part very much fun, but then, if you are very lucky, you may find a real teacher. Three real teachers in a lifetime is the very best of my luck. My first was a science and math teacher in high school, my second, a professor of creative writing at Stanford, and my third was my friend and partner, Ed Ricketts.　　My three had these things in common: They all loved what they were doing. They did not tell; they catalyzed a burning desire to know. Under their influence, the horizons sprung wide and fear went away and the unknown became knowable. But most important of all, the truth, that dangerous stuff, became beautiful and very precious.　　I shall speak only of my first teacher because in addition to the other things, she brought discovery.　　She aroused us to shouting, book waving discussions. She had the noisiest class in school and she didn’t even seem to know it. We could never stick to the subject. Our speculation ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies.　　I can tell my son who looks forward with horror to fifteen years of drudgery that somewhere in the dusty dark a magic may happen that will light up the years if he is very lucky.Among his teachers, left him a very deep impression

12.Eating an apple a day doesn' t keep the doctor away, but it does reduce the amount of trips youmake to the drug store per year. That ' s according to a new study that investigates whether there's any truth in the old saying.A team of researchers led by Dr Matthew Davis, of the University of Michigan School ofNursing,asked 8,399 participants to answer survey questions about diet and health. A total of 753were apple eaters, consuming at least 149g of raw apple per day. The remaining 7,646 were classedas non-apple eaters. When both groups answered questions on trips to the doctor and trips to thedrug store per year,the apple eaters were found to be 27% less likely to visit the druggist for drugs.Trips to the doctor were not significantly affected by apple consumption, though. "Evidence doesnot support that an apple a day keeps the doctor away. However, the small number of US adultswho eat an apple a day does appear to use fewer prescription medications," the study concludes.Apple eaters were also found to be less likely to smoke and be more likely to have a highereducational attainment than non-apple eaters. While apples do not compete with oranges, theydocontain some immune (免疫的) system-increasing vitamin C, which may be why apple-eatersvisit the druggist less. With over 8mg of vitamin C per medium-sized fruit, an apple can provideroughly 14% your daily recommended intake.Previous studies have also linked apple consumption to a lower risk of Type 2 diabetes (二型糖尿病) ,improved lung function and a lower risk of colon (结肠) cancer.What can be described as the writing style of this passage?
