2 阅读理解。 I always felt sorry for the people in wheelchair. Some people, old and weak, can not get around by themselves. Others seem perfectly healthy, dressed in business suits. But whenever I saw someone in a wheelchair, I only saw a disability, not a person. Then I fainted at Euro Disney due to low blood pressure. This was the first time I had ever fainted, and my parents said that I must rest for a while after First aid. I agreed to take it easy but, as I stepped towards the door, I saw my dad pushing a wheelchair in my direction! Feeling the color burn my cheeks, I asked him to wheel that thing right back to where he found it. I could not believe this was happening to me. Wheelchairs were fine for other people but not for me, as my father wheeled me out into the main street, people immediately began to treat me differently. Little kids ran in front of me, forcing my father to stop the wheelchair suddenly. Bitterness set in as I was thrown back and forth. "Stupid kids-they have perfectly good legs. Why can"t they watch where they are going?" I thought. People stared down at me,with pity in their eyes. Then they would look away, maybe because they thought the sooner they forgot me, the better. "I am just like you!" I wanted to scream. "The only difference is you"ve got legs, and I have wheels." People in wheelchairs are not stupid. They see every look and hear each word. Looking out at the faces, I finally understood: I was once just like them. I treated people in wheelchairs exactly the way they did not want to be treated. I realized it is some of us with two healthy legs who are truly disabled. 1. The author once ____ when he was healthy. A. laughed at disabled people B. looked down upon disabled people C. imagined herself sitting in a wheelchair D. saw some healthy people moving around in wheelchairs 2. Facing the wheelchair for the first time, the author ____. A. felt curious about it B. got ready to move around in it right away C. refused to accept it right away D. thought it was ready for his father 3. The experience of the author tells us that "____". A. life is the best teacher B. people often eat their bitter fruit C. life is so changeable that nobody can foretell D. one should not do to others what he would not like others do to him 4. Which is the best title for this passage? A. How to Get Used to Wheelchairs B. The Wheels Are as Good as Two Legs C. People with Two Legs Are Truly Healthy D. The Difference between Healthy People and the Disabled

8 阅读理解。 Sometimes, something that is considered to be negative turns out to be an advantage on the job. Though he is only l8 years old and blind, Suleyman Gokyigit is among the top computer technicians and programmers at InteliData Technologies Corp., a large software company with several offices across the United States. "After our company united with another one last October, two different computer networks were driving us crazy," recalls Douglas Braun, the InteliData president. "We couldn"t even send e-mail to each other." In three weeks Mr Gokyigit created the software needed to connect the two networks. "None of the company"s 350 other employees could have done the job in three months," says Mr. Braun. "Suleyman can see into the heart of the computer." Mr. Gokyigfi"s gift, as Mr. Braun calls it, is an unusual ability to form an idea of the inside of a machine. "The computer permits me to reach out into the world and do almost anything I want to do," says Mr. Gokyigit. The young programmer is at home with hardware as well, thanks partly to a highly developed sense of touch. Mitzi Nowakowski, an office manager at InteliData, remembers how he easily disconnected and reconnected their computer systems during a move last year. "Through feel, Suleyman can find the position of connectors, pins and wires much faster than most other people with sight," he says. Much of the student programmer"s speed comes from his ability not to be interrupted while at the computer. When typing, he listens carefully to the synthesizer (合成器). His long, thin fingers fly over the keyboard. "Nothing seems to shake his attention," says Mrs. Nowakowski, his boss. Mr. Gokyigit is the only company employee who is available (可找到的) 24 hours a day. "We consider him our top problem solver." says Mr. Braun. 1. According to Mr. Braun, Suleyman _____. A. can work wonders on computer B. is the best technician in the world C. has done a hard job in three months D. has united InteliData Technologies Corp. with another computer company 2. The underlined part "is at home with hardware" (paragraph 4) means _____. A. is good at dealing with computer hardware B. is fond of computer hardware C. works with computer hardware at home D. feels comfortable when working with computer hardware 3. Suleyman was quick while at the computer mostly because of _____. A. his blindness B. his attention on the synthesizer C. his long, thin fingers D. his ability not to be interrupted 4. Suleyman was quick while at the computer mostly because of _____. A. his blindness B. his attention on the synthesizer C. his long, thin fingers D. his ability not to be interrupted
