There are 5 tasks for you to fulfill. You should read the reading materials carefully and do the task as you are instructed.Task 1Hank Viscardi was born without legs. He had not legs but stumps (残肢) that could be fitted with a kind of special boots. People stared at him with cruel interest. Children laughed at himand called him ―Ape Man‖(猿人) because his arms practically dragged on the ground.Hank went to school like other boys. His grades were good and he needed only eight years to finish his schooling instead of the usual twelve. After graduating from school, he worked his way though college. He swept floors, waited on table, or worked in one of the college offices. During all this busy life, he had been moving around on his stumps. But one day the doctor told him even the stumps were not going to last much longer. He would soon have to use a wheelchair.Hank felt himself get cold all over. However, the doctor said there was a chance that he could be fitted with artificial legs (假肢). Finally a leg maker was found and the day came when Hank stood up before the mirror. For the first time he saw himself as he has always wanted to be - a full five feet eight inches tall. By this time he was already 26 years old.Hank had to learn to use his new legs. Again and again he marched the length of the room, and marched back again. There were times when he fell down on the floor, but he pulled himself up and went back to the endless marching. He went out on the street. He climbed stairs and learned to dance. He built a boat and learned to sail it.When World War II came, he talked the Red Crossing into giving him a job. He took the regular training. He marched and drilled along with the other soldiers. Few knew that he was legless. This was the true story of Hank Viscardi, a man without legs.36. Children laughed at Hank and called him ―Ape Man‖ because _______.A. he didn’t talk to themB. he kept away from themC. his arms touched the ground when he movedD. he couldn’t use his arms37.

None of the above38. The sentence ―he talked the Red Cross into giving him a job‖ implies that the Red Cross _______.A. was only glad to give him a jobB. gave him a job because he was a good soldierC. gave him a job after he talked to someone he knewD. was not willing to give him a job at first39. When Hank marched and drilled along with the other soldiers, he ____.A. did everything the other soldiers didB. did most of the things the other soldiers didC. did some of the things the other soldiers didD. took some special training40. The writer suggests that Hank Viscardi _________.A. had no friendsB. never saw himself as different from othersC. was very shyD. was too proud to accept help from othersTask 2In the United States, when a person becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what ―keeping up withthe Joneses‖ is about. It is the st ory of someone who tried to look as rich as his neighbors.The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horse-riding everyday. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.Momand looked around him and noticed that many people do things just to keep up with rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it ―Keeping up with the Joneses‖ because ―Jones‖ is a very common name in the Untie States. ―Keep up with the Joneses‖ came to mean keeping up with the rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.People never seem to get tried of keeping up with the Joneses. And there are ―Joneses‖ in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does, Mr. Jones always seems to be ahead.41. Some people want to keep up with the Joneses because they _____.A. want to be as rich as their neighborsB. want others to know or to think that they are richC. don’t want others to know they are richD. want to be happy42.

The underlined word ― neighborhood‖ in Para.2 means ________.A. a person who lives near anotherB. people living in an areaC. an area near the place referred toD. an area in another town or city44. Arthur Momand used the name ―Jones‖ in his series of short stories because ―Jones‖ is __________.A. an important nameB. a popular name in the United StatesC. his neighbor’s nameD. not a good name45. According to the writer, it is _____ to keep up with the Joneses.A. correctB. interestingC. impossibleD. goodTask 3Directions: The following is a passage. After reading it, you are required to complete the outline below it. You should write your answers (in no more than 3 words) briefly.Freezing can keep food fresh and safe to eat. Freezing lowers the food temperature below zero degree Celsius(摄氏). The simplest way to prepare fruits is to cut them up and place themin a container inside the freezer, in some cases it is better to permit the fruit to freeze before putting it in the container. This will keep it from sticking to the container. This is called the ―dry pack‖ method. The second way is the ―wet pack‖ method. The fruit is prepared along with some of its liquid or juice. You can add some sugar to fruits that are naturally juicy. The sugar sweetens the fruit and brings out its natural juice. Once foods have been unfrozen, they should not be frozen again. There is a danger of food poisoning if food is frozen more than once.Task 4Directions: The following is a list of airport terms.
