Summary专项练习一、Original:My neighbors children love playing hide-and-seek as all children do, but no one imagine that a game they played last week would be reported in the local newspaper.One afternoon, they were playing in the vacant lot down the corner. Young Paul, who is only five years old, found the perfect place to hide. His sister, Natalie, had shut her eyes and was counting to ten when Paul noticed the storage mail box at the corner and saw that the metal door was standing open. The mailman had just taken out several sacks of mail and had carried them to his truck which was standing at the curb a few feet away. Paul climbed into the storage box and pulled the door closed so hard that it locked. Soon realizing what he had done, he became frightened and started crying. Meanwhile, Natalie was looking for him everywhere but could not find him. It was lucky that she happened to pause at the corner for a minute and heard her brothers cries. She immediately ran to tell the mailman who hurried back from his truck to unlock the metal door. Paul was now free, but he had had such a bad scare that he could not stop crying. The mailman, however, soon found a way of making him laugh again. He told him that the next time he wanted to hide in a mail box, he should remember to put a stamp on himself!Summary:The children were playing hide-and-seek in a vacant lot one afternoon. Finding that the storage mailbox had been left open, Paul hid and locked himself in it accidentally. His sister, Natalie, heard his cries and realized where he was hiding, so she immediately told the mailman to unlock the metal door. After letting him out, the mailman made him stop crying by telling him to put a stamp on himself the next he wanted to hide in a mailbox.二、Original:Why do some animals die out?In the past two hundred years people have caused many kinds of animals to die out-to become extinct. People keep building houses and factories in fields and woods. As they spread over the land, they destroy animals homes. If the animals cant find a place to live, they die out. Sixteen kinds of Hawaiian birds have become extinct for this reason. Other animals, such as the Florida Key deer, may soon die out because they are losing their homes. Hunters have caused some animals to become extinct, too. In the last century, hunters killed all the passenger pigeons in North America and most of the buffalos.Today they are fast killing off hawks and wolves. Pollution is killing many animals today, too. As rivers become polluted, fish are poisoned. Many die. Birds that eat the poisoned fish cant lay strong, healthy eggs. New birds arent born. So far, no animals have become extinct because of pollution. But some, such as the bald eagle and the brown pelican, have become rare and may die out.Scientists think that some animals become extinct because of changes in climate. The places where they live become hotter or cooler, drier or wetter. The food that they eat cannot grow there any more. If the animals cant learn to eat something else, they die. Dinosaurs may have died out for this reason.Summary:In the past two hundred years, many kinds of animals have died out. There are several reasons for it. First, people keep building houses and factories in fields and woods, which destroys animals homes. Then, hunters killing has also caused some animals to become extinct. Besides, some animals arent able to bear strong offspring and nor do they have enough food to eat because of pollution and climatic changes.三、Original:Of all the games held throughout Greece, those staged at Olympia in honor of Zeus are the most famous. The Games, like all Greek games, were an intrinsic part of a religious festival. Held every four years between August 6 and September 19, they occupied such an important place in Greek life that time was measured by the interval between them an Olympiad. Although the first Olympic champion listed in the records was one Coroebus of Elis, a cook, who won the sprint race in 776 BC, it is generally accepted that the Games were probably at least 500 years old at that time. According to one legend, they were founded by Heracles, son of Alcmene.The Games were held at Olympia in the city-state of Elis, on a track about 32 meters (35 yards) wide. The racing length was one stade, a distance of about 192 meters (210 yards) which was one length of the track. At the meeting in 776 BC, there was apparently only one event, the stade, but other events were added over the ensuing decades. In 724 BC a two-length race, diaulos, roughly similar to the 400-meter race, was included and four years later, the dolichos, a long-distance race possibly to be compared to the modern 1500- or even 5000-meter event, was added . wresting and the pentathlon were introduced in 708BC. The latter was an all-around competition consisting of five events the long jump, javelin throw, discus throw, foot race, and wresting
