2015考研英语阅读理解精读P18—医学

2015考研英语阅读理解精读P18—医学 Passage 18(Doctor-assisted Suicide：Is It Ever an Option?) Should doctor-assisted suicide ever be a legal option? It involves the extreme measure of taking the life of a terminally ill patient when the patient is in extreme pain and the chances for recovery appear to be none.Those who argue against assisted suicide do so by considering the roles of the patient，the doctor，and nature in these situations. Should the patient take an active role in assisted suicide? When a patient is terminally ill and in great pain，those who oppose assisted suicide say that it should not be up to that patient to decide what his or her fate will be.There are greater powers at work that determine when a person dies，for example，nature.Neither science nor personal preference should take precedence over these larger forces. What role should the doctor have? Doctors，when taking the Hippocratic oath，swear to preserve life at all costs，and it is their ethical and legal duty to follow both the spirit and the letter of this oath.It is their responsibilities to heal the sick，and in the cases when healing is not possible，then the doctor is obliged to make the dying person comfortable.Doctors are trained never to hasten death.Those who oppose assisted suicide believe that doctors who do help terminally ill patients die are committing a crime，and they should be dealt with accordingly.Doctors are also，by virtue of their humanness，capable of making mistakes.Doctors could quite possibly say，for instance，that a cancer patient was terminal，and then the illness could later turn out not to be so serious.There is always an element of doubt concerning the future outcome of human affairs. The third perspective to consider when thinking about assisted suicide is the role of nature.Life is precious.Many people believe that it is not up to human beings to decide when to end their own or another’s life.Only nature determines when it is the right time for a person to die.To assist someone in suicide is not only to break criminal laws，but to break divine 1aws as well. These general concerns of those who oppose assisted suicide are valid in certain contexts of the assisted suicide question.For instance，patients cannot always be certain of their medical conditions.Pain clouds judgment，and so the patient should not be the sole arbiter of her or his own destiny.Patients do not usually choose the course of their medical treatment，so they shouldn’t be held completely responsible for decisions related to it.Doctors are also fallible，and it is understandable that they would not want to make the final decision about when death should occur.Since doctors are trained to prolong life，they usually do not elect to take it by prescribing assisted suicide. I believe that blindly opposing assisted suicide does no one a service.If someone is dying of

考研英语阅读理解精读100篇之经济类 unit1 unit1 Some of the concerns surrounding Turkey’s application to join the European Union, to be voted on by the EU’s Council of Ministers on December 17th, are economic-in particular, the country’s relative poverty. Its GDP per head is less than a third of the average for the 15 pre-2004 members of the EU. But it is not far off that of one of the ten new members which joined on May 1st 2004 (Latvia), and it is much the same as those of two countries, Bulgaria and Romania, which this week concluded accession talks with the EU that could make them full members on January 1st 2007. Furthermore, the country’s recent economic progress has been, according to Donald Johnston, the secretary-general of the OECD, "stunning". GDP in the second quarter of the year was 13.4% higher than a year earlier, a rate of growth that no EU country comes close to matching. Turkey’s inflation rate has just fallen into single figures for the first time since 1972, and this week the country reached agreement with the IMF on a new three-year, $10 billion economic programme that will, according to the IMF’s managing director, Rodrigo Rato, "help Turkey... reduce inflation toward European levels, and enhance the economy’s resilience". Resilienc e has not historically been the country’s economic strong point. As recently as 2001, GDP fell by over 7%. It fell by more than 5% in 1994, and by

初中英语数词专项练习

数词数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。一. 基数词 1. 基数词就注意以下几点：（1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如： eighty-five 85 twenty-six 26 （2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and连接。如： three hundred and sixty-five 365 two hundred and six 206 （3）基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或several修饰时，必须用单数。如： several hundred year’s ago几百年前 two thousand students两千个学生 2. 基数词的特殊用法：（1）表示“几十年代”或“几十岁”时，用逢十的基数词的复数形式。如： in the 1990’s 20世纪90年代 in o ne’s twenties在某人20多岁时（2）用在习语中。如： in twos and threes三三两两地二. 序数词序数词应注意的几点事项： 1. 多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： forty-two 42 forty-second第42 nine-hundred 900 nine-hundredth第900 2. 当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如： 21st第21 32nd第32 3. 序数词前一般要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有具体范围的限制）。如： Though he had failed twice, he wanted to try a third time. 尽管他已失败了两次，他还想再试一次。 The little monkey had had three apples, and he wanted to eat a fourth one. 那只小猴子已经吃了3个苹果，他还想再吃一个。三. 分数和百分数 1. 分数（1）分数的分子用基数词，分母用序数词。如： one fifth五分之一 one tenth十分之一（2）当分子大于1时，分母用序数词的复数。如： two thirds三分之二 five eighths八分之五（3）当分子是1时，可以用one也可以用a。如： a second = one second a third = one third （4）当分母是2和4时，分别可以用half和quarter代替。如：

2009考研英语阅读理解精读100篇(2)

TEXT 2 He emerged, all of a sudden, in 1957: the most explosive new poetic talent of the English post-war era. Poetry specialised, at that moment, in the wry chronicling of the everyday. The poetry of Yorkshire-born Ted Hughes, first published in a book called “The Hawk in the Rain” when he was 27, was unlike anything written by his immediate predecessors. Driven by an almost Jacobean rhetoric, it had a visionary fervour. Its most eye-catching characteristic was Hughes's ability to get beneath the skins of animals: foxes, otters, pigs. These animals were the real thing all right, but they were also armorial devices—symbols of the countryside and lifeblood of the earth in which they were rooted. It gave his work a raw, primal stink. It was not only England that thought so either. Hughes's book was also published in America, where it won the Galbraith prize, a major literary award. But then, in 1963, Sylvia Plath, a young American poet whom he had first met at Cambridge University in 1956, and who became his wife in the summer of that year, committed suicide. Hughes was vilified for long after that, especially by feminists in America. In 1998, the year he died, Hughes broke his own self-imposed public silence about their relationship in a book of loose-weave poe ms called “Birthday Letters”.In this new and exhilarating collection of real letters, Hughes returns to the issue of his first wife's death, which he calls his “big and unmanageable event”. He felt his talent muffled by the perpetual eavesdropping upon his every move. Not until he decided to publish his own account of their relationship did the burden begin to lighten. The analysis is raw, pained and ruthlessly self-aware. For all the moral torment, the writing itself has the same rush and vigour that possessed Hughes's early poetry.

2015考研英语阅读理解精读P18—工学类 Passage 18 Tennis hopeful Jamie Hunt, 16, felt he could not become a world-class junior player while attending a regular school. The international circuit has players on the road 50% of the time--and it's hard to focus on your backhand when you're worrying about being on time for homeroom. So last year Hunt, who hones his ground strokes at Elite TNT Tennis Academy in April Sound, Texas, enrolled for academics in the $9,750-a-year University of Miami Online High School (UMOHS), a virtual school that caters to athletes. "The online school gives me the flexibility I need," says Hunt. "The workload is the same, but I can do it anywhere. It's nicer to ask a question face-to-face with a teacher, but in some ways it prepares me better for college because I have to be more independent." A year ago, Hunt's world junior ranking was 886; now it's 108. Virtual high schools, which allow students to take classes via PC, have emerged as an increasingly popular education alternative, particularly for on-the-go athletes. UMOHS has more than 400 students enrolled, 65% of whom are athletes. Accredited by the 100-year-old Southern Association of Colleges and Schools, UMOHS offers honors and advanced-placement classes. All course material is online, along with assignments and due dates. For help, says principal Howard Liebman, "a student may e-mail, instant message or call the teacher." Dallas mom Lori Bannon turned to another online school, Laurel Springs in Ojai, Calif. Bannon, who has a medical degree from Harvard, didn't want to compromise the education of her daughter Lindsay, 13, an élite gymnast who spends eight hours a day in the gym. "Regular school was not an option," says Bannon, "but I wanted to make sure she could go back at grade level if she quit gymnastics." Laurel Springs' enrollment has increased 35% a year for the past four years, to 1,800 students. At least 25% are either athletes or child entertainers. Educators are split on the merits of such schools. Paul Orehovec, an enrollment officer for the University of Miami, admits, "I was somewhat of a skeptic. But when I looked into their programs and accreditation, I was excited. UMOHS is the first online school to be granted membership in the National Honor Society." Kevin Roy, Elite's director of education, sees pitfalls and potential in virtual schools. "You will never have that wonderful teacher who inspires you for life," says Roy. "But the virtual school offers endless possibilities. I don't know where education's imagination will take this." 注(1)：本文选自Time;11/29/2004, p149-149, 1/2p, 1c; 注(2)：本文习题命题模仿对象2004年真题text 4第1、2题(1、2)，text 1 第2 题(3)，text 3第5 题(5)和2000年真题text 4第4题(4); 1.

初中英语数词专项

数词讲解专项练习 1 数词的讲解一、定义：表示数目或顺序二、分类：分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。三、基数词的构成： 1）1-12的基数词是独立的单词，即：one ，two ，three ，four ，five ，six ，seven ，eight ，nine ，ten ，eleven ，twelve 。 2）13-19的基数词以-teen 结尾。如：fourteen ，seventeen 等，但13，15，18较特殊，13—thirteen, 15—fifteen, 18—eighteen 。 3）20-90的整十位均以-ty 结尾。如：sixty ，ninety ，但20，30，40，50，80较特殊，20—twenty, 30—thirty, 40—forty, 50—fifty, 80—eighty 。 4）十位数与个位数之间要加连字符号"-" ，如：28-twenty-eight ，96-ninety-six 。 5）百位和十位（若无十位则和个位）之间加and ，如： 148—one hundred and forty-eight 406—four hundred and six 6）hundred （百），thousand （千），million （百万），billion （十亿）等前面即使有具体的数词，several, some, many也不能在它们的后面加-s 。如：six hundred，eight million。如果表示不确定数目时，用hundreds of /thousands of /millions of /billions of +名词复数, 前面不能再加数字。 7）1000以上的数字，从后往前数每三位加一个逗号" ，" 第一个逗号前为千（thousand ），第二个逗号前为百万（million ），第三个逗号前为billion （十亿）。英语中无“万”这个词，我们可以用" 几十个千（thousand ）" 表示几万，" 几百个千（thousand ）" 表示" 几十万" 。如：2，510＝two thousand five hundred and ten 84，296＝eighty-four thousand two hundred and ninety-six 274，350＝two hundred and seventy-four thousand three hundred and fifty。四、序数词的构成： 1）序数词一般是以与之相应的基数词尾加-th 构成，如：fourth, tenth, 但以下的这些基数词变为序数词时，有特别之处。 One —first, two —second, three —third, five—fifth, nine —ninth, twelve —twelfth 2）以_ty 结尾的单词，要先变y 为i, 在加-eth. 。如：thirty —thirtieth, fifty—fiftieth 3）以one, two, three 等结尾的多位数词，要将个位数变成序数词。如： twenty-one —twenty-first, one hundred and one—one hundred and first 注意：序数词前常用定冠词，有时还可以用不定冠词a/an 则表示" 又一" 的意思。（没有具体范围的限制）如： Mr. Brown has a second car. 布朗先生另外还有一辆车。 He has tried a second time. 他又尝试了一次。五、数词的应用 1)时刻的表示:小时、点钟、分钟、秒钟要用基数词。 ①“几点钟”用基数词加o'clock 。o'clock 可省略。如:5点钟-five (o'clock ) ②“几点过几分” , ≤30分钟" 用介词past 。如: 7:15— fifteen/ a quarter past seven 7:30— half past seven
