2 Joseph Goldberger was a doctor for the Unite States Public Health Service. In 1912, he began to study a disease that was killing thousands of people in the South. The disease was pellagra(烟酸缺乏病). Doctor Goldberger traveled to the state of Mississippi where many people had pellagra. He studied the patients and their families. Most of the people were poor. The doctor came to believe that the disease was not passed from one person to another, but instead had something to do with food. He received agreement from state officials to test this idea at a prison(监狱). Prisoners were offered pardons if they took part. One group of prisoners received their usual food, mostly corn. A second group ate meat, fresh vegetables and milk. Members of the first group developed pellagra. The second group did not. But some experts refused to accept that poor food caused pellagra. They thought there were other causes. So Doctor Goldberger put blood(血液) from a person with pellagra into his own body. He even took pills that had blood from pellagra patients. An assistant also took part in the experiments. So did Doctor Goldberger’s wife. None of them got sick. Later, the doctor discovered that a bit of dried brewer’s yeast(酿酒的酵母) each day could prevent pellagra. Joseph Goldberger died of cancer in 1929. He was 55 years old. Several years later, researchers discovered the true cause of pellagra: having little of the vitamin B. 小题1: How old was Doctor Goldberger when he began to study pellagra? A．22. B．30. C．38. D．55. 小题2:The underlined part “this idea” (in Paragraph 3) refers to . A．the guessing that pellagra had something to do with food B．a kind of yeast that prevented pellagra C．pellagra that was easily passed from one person to another D．a poor food that caused pellagra 小题3: Which is the right order about what Doctor Goldberger did? a. He did a test on prisoners at a prison. b. He did the experiments on himself. c. He came to Mississippi to study the patients and their families. d. He found poor food was easy to cause pellagra. e. He discovered a little dried brewer’s yeast every day could prevent pellagra. A．a, d, c, e, b B．c, a, d, b, e C．b, e, c, a, d D．c, b, e, a, d 小题4: This passage mainly tells us .

4 阅读下面的文字，完成下题。人生的四种境界张世英　　按照人的自我发展历程、实现人生价值和精神自由的高低程度，人生境界可分为四个层次，即欲求境界、求知境界、道德境界和审美境界。　　最低境界为“欲求境界”。人生之初，在这种境界中只知道满足个人生存所必需的最低欲望，故以“欲求”称之。当人有了自我意识以后，生活于越来越高级的境界时，此种最低境界仍潜存于人生之中。现实中，也许没有一个成人的精神境界会低级到唯有“食色”的欲求境界，而丝毫没有一点高级境界。以欲求境界占人生主导地位的人是境界低下而“趣味低级”的人。　　第二种境界为“求知境界”。在这一境界，自我作为主体，有了进一步认知作为客体之物的规律和秩序的要求。有了知识，掌握了规律，人的精神自由程度、人生的意义和价值就大大提升了一步。所以，求知境界不仅从心理学和自我发展的时间进程来看在欲求境界之后，而且从哲学和人生价值、自由之实现的角度来看，也显然比欲求境界高一个层次。　　第三种境界为“道德境界”。它和求知境界的出现几乎同时发生，也许稍后。就此而言，把道德境界列在求知境界之后，只具有相对的意义。但从实现人生意义与价值的角度和实现精神自由的角度而言，则道德境界之高于求知境界，是不待言的。发展到这一水平的“自我”具有了责任感和义务感，这也意味着他有了自我选择、自我决定的能力，把自己看作是命运的主人，而不是听凭命运摆布的小卒。但个人的道德意识也有一个由浅入深的发展过程：当独立的个体性自我尚未从所属群体的“我们”中显现出来之时，其道德意识从“我们”出发，推及“我们”之外的他人。　　人生的最高精神境界是“审美境界”。这是因为此时审美意识超越了求知境界的认识关系，它把对象融入自我之中，而达到情景交融的意境；审美意识也超越了求知境界和道德境界中的实践关系。这样，审美境界既超越了认识的限制，也超越了功用、欲念和外在目的以及“应该”的限制，而成为超然于现实之外的自由境界。　　在现实的人生中，这四种境界错综复杂地交织在一起。很难想象一个人只有其中一种境界而不掺杂其他境界，只不过现实的人，往往以某一种境界占主导地位，其他次之。于是我们才能在日常生活中区分出某人是低级境界、低级趣味的人，某人是高级境界、高级趣味的人，某人是以道德境界占主导地位的道德家，某人是以审美境界占主导地位的真正的诗人、真正的艺术家……（节选自2009年12月31日《光明日报》有删改） 1．关于“人生境界”的理解，符合原文意思的一项是（） A．它存在于人的自我发展历程中，体现着实现人生价值和精神自由的高低程度。 B．它由四个层次组成，从幼年到成人，人的每一个时期都要经历这四个层次。 C．现实的人生中，它是一个整体，是由从低到高的四种境界错综复杂地交织在一起的。 D．每个人的人生境界表现错综复杂，不同层次的人生境界分别主导着人生的不同阶段。 2．对于“求知境界”与“道德境界”关系的表述，不符合原文意思的一项是（） A．作者把“道德境界”列在“求知境界”之后，并不意味着前者就一定比后者出现得晚。 B．达到了“求知境界”，人具备了知识，掌握了规律，为“道德境界”的产生创造了条件。 C．责任感与义务感使“道德境界”不同于“求知境界”，并高于“求知境界”。 D．“求知境界”虽也把“自我”作为主体，但这个“自我”却不同于“道德境界”中的“自我”。 3．下列表述，符合原文意思的一项是（） A．“欲求境界”是人生的最低境界，这种境界是任何一个具有高级境界的人所极力排斥的。 B．“求知境界”中的“自我”已不再仅满足于个人生存所必需的最低欲望，而对规律与秩序有了认知的要求。 C．“道德境界”中的人不再关注自我，而已经有意识地把“我们”作为自我选择、决定时的中心了。 D．“审美境界”是人生最高的精神境界，到了这一境界就能自由地超越并摒弃其他三种境界。

10 I had been rather proud of myself when my friends and family got the ticket, whether it was for speeding, parking or stop sign violations(违反). It was something that happened to others. But last Friday I joined the club. I was asked to do a new project last week. On Friday morning on my way to work, I suddenly remembered that I had spent the past six weeks without considering that I had a week’s vacation pla nned during that time. I was very disappointed with myself for not remembering it. The truth is that I was not paying enough attention to my driving and I did not come to a complete stop at the stop sign in front of a school. I was so distracted(思想不集中的) that I didn’t even notice I had a policeman on my tail with his lights flashing. Finally I looked in my mirror and caught on. The policeman was rude and took my papers. Luckily, I had everything up to date and since I had never had a ticket before, there was nothing for him to do but write me a ticket. While I was sitting there in the seat of “shame”, I felt bad. If I had been that distracted and a child had run onto the road, perhaps I would have not reacted as well as I could have. It was a wake-up call. People at work asked me if I tried to talk my way out of it. Frankly, it never occurred to me. I felt guilty（有罪的）. Now I no longer have a clean driving record. Please be careful out there, as a moment’s distraction can lead to tragedy（悲剧）. 小题1:What is this passage mainly about? A．The writer’s most unforgettable experience. B．How the writer got her first ticket. C．An accident caused by the writer. D．Why the writer is always so careful. 小题2:We can infer that the underlined part “the club” in Paragraph 1 here refers to . A．people who are crazy about driving cars B．a club for drivers without much experience C．people who get tickets for breaking traffic rules D．a club for people to talk about their driving stories 小题3:What made the writer unable to focus on(集中思想) her driving? A．Planning how to spend the vacation. B．Thinking of the forgotten vacation. C．Thinking about her work. D．Missing her children. 小题4:When the writer received the ticket, she . A．felt lucky that she was an experienced driver B．was so nervous that she shook all over C．was ashamed of herself for being distracted D．was worried about being laughed at
