【题目】A black and white kitten with a broken back lay on animal doctor Betsy Knenon's examination table. A regular customer had rushed him to her office after his pet dog brought the cat home in his mouth. The dog's owner was horrified, believing that his pet had caused the cat's injuries. But Kennon found no teeth marks or bite wounds, which showed that the dog had probably saved, not harmed, the kitten.

In Kennon’s opinion, however, the cat was a hopeless case. Many doctors would have put down such a badly hurt animal. But she couldn’t be so cruel. The kitten’s bright eyes and sad face had won her over. There was no way of finding his owner, so Kennon, a single woman aged 56, decided to keep him.

She gave him a round of shots and fed him food mixed with medicines. He couldn’t move his back legs but soon started pulling himself forward with his front legs. The doctor named him Scooter and contacted a company that makes carts for disabled animals. Scooter took to his new wheels like a natural. In no time he was able to move freely, if somewhat awkwardly, around Kennon’s office, home and even her backyard. The sight of the determined Scooter was uplifting and amusing in equal measure and Kennon had to smile each time the cat entered the room.

Kennon was convinced that her kitten could share his high spirits with others. So she took Scooter to the local hospital to see if he could help the patients. His first patient was an elderly woman who’d had a stroke and hadn’t spoken to anyone for two days. Scooter jumped out of Kennon’s arms and onto the bed, rolled over to the patient, and lay gently near her cheek, purring softly. The woman looked at Scooter. “Kitty,” she murmured as she began to talk to him. Amazed, Kennon turned to the doctor--- and saw that she was in tears. The cat had engineered a small miracle.

Today Scooter spends about ten hours a month working with patients who are recovering from strokes and injuries. Again and again, Kennon watches as her cat provides hope and comfort. As one patient who’d lost her leg in a car accident said, “If he can do it, so can I.”

【1】 From Paragraph 1, we know that ___________.

A. the dog’s owner was a stranger to Kennon

B. the cat had several bite marks on its body

C. the dog was extremely cruel to the cat

D. who actually injured the cat was unknown

【2】 The underlined phrase “put down” in Paragraph 2 most probably means___________.

A. hurt

B. killed

C. refused

D. replaced

【3】 Why did Kennon decide to keep the cat?

A. She wanted a companion.

B. The cat’s owner abandoned him.

C. She liked the cat.

D. The cat was hopeless.

【4】 How did Kennon help the cat move around?

A. By curing his broken back.

B. By getting him a special cart.

C. By feeding him medicines.

D. By exercising him in her backyard.

【5】 According to the passage, what is the main reason that the cat works miracle?

A. He is able to inspire others.

B. Patients feel sympathy for him.

C. People are amused by his appearance.

D.He has the ability to cure the ill.

【题目】阅读下面的文字，完成（1）（4）题。

吴文俊的数学世界

吴文俊小学时成绩平平，也没有显示出独特的数学才华，初中时数学甚至得过零分，高中时最喜欢的是物理而非数学，但他从小就对读书有浓厚兴趣，初中时国文成绩一直不错，尽管高三时物理得了满分，但教物理的赵贻经老师却看出了他的数学潜力，力荐他入数学系。正始中学决定，吴文俊必须报考数学系，才能得到每年一百块大洋的奖学金，加之他父母又不放心独子离开上海，吴文俊就进入了上海交大数学系，所谓“知之不如好之，好之不如乐之”，吴文俊向来是以兴趣为先导来读书的，因为他对物理有兴趣，甚至一度想要转系。是大三时教数学的武崇林老师帮助他摆脱了专业上的困惑，使他认识到数学的巨大魅力。

1940年，吴文俊从交大毕业，先后在育英中学、培真中学担任数学教员，直到1946年见到了影响他一生的恩师陈省身，他才由一个普通的中学数学老师成为数学研究所的专业研究员。对于吴文俊的数学研究，他的学生高小山总结说：“吴先生做拓扑研究，一下子就能抓住核心问题，为代数拓扑学的兴起作出了影响深远的贡献。他从事机器定理证明也是这样，极其敏锐地看出了信息时代数学的发展趋势，他的研究受到中国古代数学的启发，汲取了中国传统数学的养分。使用吴先生的方法，几乎所有数学定理的证明，都可以由计算机来完成，从而让人类把精力放到更加宏观的层面上去思考问题。”

对吴文俊来说，虽然最初选择数学是被动的，但综观其一生，数学已逐渐成为他生命的一部分。从事数学研究，吴文俊特别强调数学思维。他说：“要创新，就要独立思考，就不能总是跟着人家亦步亦趋，当然开始的时候参考借鉴也是必要的，牛顿就说过，他之所以获得成功，因为他站在巨人的肩膀上，才能看得远，所以不能忽略学习，可是除了学习之外，还要能够独立思考，这是创新的必要条件。现在摆在中国面前的是，数学就要靠下一代、下下代在创新方面取得巨大成功，中华民族才可以得到复兴。”吴文俊自己的经历就是很好的例子。他在数学上的一系列成就，特别是他运用机械化思想来考察数学，发现了数学的不同侧面，并建立了新的模式，这全得益于他的独辟蹊径。

对我国的数学基础教育，吴文俊也颇有心得。我国中学生多次在国际奥数竞赛中获奖，被当作我国数学教育成功的证明，但吴文俊更赞同丘成桐的观点：“奥数应该是一种建立在兴趣之上的研究性、高层次学习，中国的奥数学习过分关注海量题目，直接与考试、竞赛挂钩，对系统学数学不利。作为基础学科，应着重引导学习的兴趣，不应当过分追求功利。”吴文俊同样清醒认识到：“竞赛获奖固然可贵，但也不能看得过重，因为它不能代表学生对数学的深度理解，也不能有效地训练数学思维。”他认为，数学教育更重要的是培养数学的思维方式。

有人曾揶揄数学家迂腐，吴文俊不但不迂腐，而且兴趣广泛，内心充满童趣，他说：“我是个想怎样就怎样的人，想玩就玩，想工作了就会安安静静地工作，从不多想。”他喜欢看电影、读历史小说，也喜欢看围棋比赛。老伴说他“贪玩”，他却说：“读历史书籍、看历史影片，帮助了我的学术研究；看围棋比赛，更培养了我的全局观念和战略眼光。”

吴文俊37岁时就获得了国家自然科学一等奖，四十多年后，他再次获得国家最高科技奖。如此长的学术生命，在数学界是非常罕见的。当记者提出疑问时，吴文俊反问道：“我为什么不能保持这么长的学术生命？”在他看来，学术生命是能够终生保持的，很多人做不到，那是他们自己的问题，应该自我反省。他特别强调研究数学要下扎实的功夫。他说：“外国许多数学家，尽管有的我非常佩服，可是我并不认同他们靠所谓巧思妙想研究数学的办法。应该根据客观实际具体分析，一切以事实为主。这是我主要的想法。”
