Ⅲ.读后续写 阅读下面材料，根据其内容和所给段落开头语续写一段，使之构成一篇完整的短文。 John Brown is a college student, who is performing well in all aspects.But when he was two years old, he suffered from autism (孤独症) that delayed his brain's growth.The basic symptoms included inability to pick up social cues, a refusal to interact with friends or family, and a lack of skills in processing speech, thinking and learning. John's parents, who were teachers, were initially shocked at the revelation.What's worse, they learned the bad news that John was going to become blind when he grew up.Even so, they kept his illness as a secret under medical advice, and were always there for their son. As little John was at school, he began to notice how other kids were able to answer questions in class a lot faster than he did.Because of his significantly slow thinking, it took him many minutes to come up with an answer to the best of his abilities.But he worked harder than other classmates for his coursework, such as sitting in front of the class to read the words on the blackboard better, and spending longer time studying to pass tests. John's parents still stood by him, encouraging him and saying, “You are the best！” They recorded every detail of his growth in a notebook.But they were not prepared for how the following events positively changed their son's life forever.Through primary and secondary schools, John began to change from keeping to himself to interacting with his classmates. When he entered the college, he joined the marching band, something he never had any interest in, but his mom convinced him that it was a great way to not only make friends, but also help gain more confidence in himself.Later, he played the trumpet (小号) well and got along well with the band members, despite the fact he was still unaware about his illness. However, one day when John came home from college, he accidentally found a medical chart in his parents' room.It described his autism and the risk of blindness, information that had been kept hidden from him for most of his life. 注意： 1.续写词数应为80左右； 2．要求逻辑通顺、情节合理，重点描写John是如何积极面对生活挑战的。 John was shaken by this discovery but he also felt a sense of relief.　 参考范文： John was shaken by this discovery but he also felt a sense of relief. He finally understood why he had always felt different and out of place.He no longer needed to feel guilty for not fitting in or blamed himself for his limitations.Day after day, he learned to embrace his autism and use it to his advantage.He no longer feared his blindness and instead accepted it as a part of who he is.His marching band experience helped him build friendships and confidence, and he also used his trumpet-playing skills to lead the band in their performances.John Brown is proof that autism and blindness cannot stop one's success. [阅读拓展训练] Feifei, an 11-year-old boy from Xuzhou, Jiangsu Province, suffered from a sudden acute eye disease which has almost led to blindness.The disease was caused by excessive (过度的) eye fatigue (疲劳) during the winter vacation, during which he played computer games for continuous 10 days and nights. Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products.This is followed by a series of health problems, with the most typical case being myopia (近视), or near-sightedness. According to the latest research report released by the World Health Organization (WHO), the myopia rate among Chinese teenagers ranks first in the world — 70 percent of high school and college students.The rate is nearly 40 percent in primary school students, while it is only 10 percent for their peers in the United States. There are at least 10 million people in China with severe myopia, and they are likely to get pathological (病理学的) myopia in middle age.Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness, Xu Xun, director of the ophthalmology (眼科学) department at Shanghai General Hospital, pointed out. Experts explain that two major factors lead to the high rate of myopia among Chinese people.One is high academic pressure, and the other one is excessive use of electronic devices over a long period of time.Genetics, on the other hand, is not the main reason, as only 20 percent of Chinese people had myopia in the 1960s. “Teenagers are now faced with severe academic pressure, which means they often study without natural light.This increases their risk of becoming near-sighted，” Xu said. Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process. 语篇解读：本文是一篇说明文。文章主要介绍了目前中国青少年近视的现状以及引起青少年近视的主要原因，并提出了预防近视的建议。 √ 1．Why does the author mention Feifei's experience in the first paragraph? A．To advise people to protect their eyes. B．To introduce the topic of near-sightedness. C．To inform people of the cause of blindness. D．To show that Feifei developed an eye disease. 解析：推理判断题。根据全文可知，第二至七段都在讲青少年近视的问题，由此可推知，第一段的例子是为了引出近视的话题。 √ 2．What can be learnt from the passage? A．Near-sightedness may cause other health problems. B．There are more near-sighted students in the United States. C．70 percent of Chinese students in primary schools are near-sighted. D．Pathological myopia is most likely to cause blindness. 解析：细节理解题。根据第四段第二句“Pathological myopia can't be treated with glasses or surgery, and it is one of the biggest factors that lead to blindness”可知，病理学的近视可能是致盲的最大因素之一。 √ 3．Which of the following can be a main reason for myopia? A．Genetics factors. B．Low academic pressure. C．Overuse of electronic devices. D．Reading in natural light. 解析：细节理解题。根据第五段第二句“One ...and the other one is excessive use of electronic devices over a long period of time.”可知，近视的主要原因之一是长时间过度使用电子设备。 √ 4．What will be probably discussed in the following paragraph? A．The significance of protecting eyesight. B．Youngsters' bad behavior leading to myopia. C．The relationship between youngsters and their parents. D．Parents' role in helping youngsters protect their eyesight. 解析：推理判断题。文章最后一段提到专家建议，为保护青少年的视力，青少年需要在学习和休息之间保持平衡，并且家长在此过程中需要起积极的作用。由此可知，文章接下来将可能讨论父母在帮助孩子保护视力方面起的作用。 5. 6. $$null
