国际商会国际仲裁院的仲裁庭于1989年依据该院仲裁规则，对美国某电器公司与阿根延某公司之间由于股份买卖而产生的争议在墨西哥进行了审理，仲裁庭在裁决中认定，阿根廷某公司未能证明美国某电器公司在1979年向其出售股票时有欺诈行为，但美国未能遵守“信用所要求的善意的原则”，裁决美国某电器公司向阿根廷某公司支付6793000美元的损害赔偿，另加12%的年复利，自1985年3月14日起算，以及100万美元的律师费和40万美元的仲裁费。 该裁决作出后，美国某电器公司向美国法院提出撤销和拒绝承认与执行该裁决的诉讼。阿根廷某公司则对美国某电器公司提出反诉，请求法院驳回美国某电器公司关于撤销仲裁裁决的诉讼请求，理由是，该法院根据《纽约公约》对此无管辖权，同时请求法院依据《纽约公约》第3条承认与执行仲裁裁决。 问： 美国法院是否有权撤销该仲裁裁决简要说明原因。
Directions:You are going to read a list of headings and a text about natural selection. Choose the most suitable heading from the list A—F for each numbered paragraph (41—45). The first and last paragraphs of the text are not numbered. There is one extra heading which you do not need to use. Mark your answers on ANSWER SHEET 1.[A] The impotence of creationism.[B] Natural selection acts by competition.[C] The role of natural selection in this colorful world[D] The delicate hierarchy of the natural system.[E] The agency of selection can account for more cases.[F] No leaps in natural evolution.As each species tends by its geometrical rate of reproduction to increase excessively in number; and as the modified descendants of each species will be enabled to increase by as much as they become more diversified in habits and structure, so as to be able to seize on many and widely different places in natural selection to preserve the most divergent offspring of any one species. Hence, during a long-continued course of modification, the slight differences characteristic of varieties of the same species, tend to be augmented into the greater differences characteristic of the species of the same genus.41. __________New and improved varieties will inevitably displace and destroy the older, less improved, and intermediate varieties; and thus species are rendered to a large extent defined and distinct objects. Dominant species belonging to the larger groups within each class tend to give birth to new and dominant forms; so that each large group tends to become still larger, and at the same time more divergent in character. But as all groups cannot thus go on increasing in size, for the world would not hold them, the more dominant groups beat the less dominant.42. __________This tendency in the large groups to go on increasing in size and diverging in character, together with the inevitability of much extinction, explains the arrangement of all the forms of life in groups subordinate to groups, all within a few great classes, which has prevailed throughout all time. This grand fact of the grouping of all organic beings under what is called the Natural System, is utterly unexplainable on the theory of creation.43. __________As natural selection acts solely by accumulating slight, successive, favorable variations, it can produce no great or sudden modifications; it can act only by short and slow steps. We can see why throughout nature the same general end is gained by an almost infinite diversity of means, for every peculiarity when once acquired in long inherited, and structures already modified in many different ways have to be adapted for the same general purpose. We can, in short, see why nature is extravagant in variety, though not generous in innovation. But why this should be a law of nature if each species has been independently created no man can explain.44. __________Many other facts are, as it seems to me, explicable on this theory. How strange it is that a bird, under the form of a woodpecker, should prey on insects on the ground and that upland geese which rarely or never swim, should possess webbed feet, and so in endless other cases. But on the view of each species constantly trying to increase in number, with natural selection always ready to adapt the slowly varying descendants of each to any unoccupied or ill-occupied place in nature, these facts cease to be strange, or might even have been anticipated.45. __________We can to a certain extent understand how it is that there is so much beauty throughout nature; for this may be largely attributed to the agency of selection. That beauty, according to our sense of it, is not universal, must be admitted by every one who will look at some hideous bats with a distorted resemblance to the human face. Sexual selection has given the most brilliant colors, elegant patterns, and other ornaments to the males. With birds it has often rendered the voice of the male musical to the female, as well as to our ears. Flowers and fruit have been rendered conspicuous by brilliant colors in contrast with the green foliage, in order that the flowers may be readily seen, visited and fertilized by insects.As natural selection acts by competition, it adapts and improves the inhabitants of each country only in relation to their co-inhabitants; so that we need feel no surprise at the species of any one country being beaten and supplanted by the naturalized productions from another land. The wonder indeed is, on the theory of natural selection, that more cases of the want of absolute perfection have not been detected. 41
In New York, there is now a school with no daily lessons, no class teachers, not even a school building. The "school" is a now project. It is called "City-as-School" and the name means just that, the city itself is the place where, 350 students, between the age of 15 and 18, learn their lessons. Students choose areas of work which interest them and then they help to do that work. For instance, one girl spends her week in the offices of a Congresswoman — an elected official — helping the public with problems such as pensions, housing, etc. Then she goes to help in a theatre for a day and she spends one day a week taking first-year courses at college. City-as-School is 30 years old. The education system in New York accepts it now, as an alternative to final years at school. But can it replace ordinary lessons Well, students have to pass maths and science exams before they enter the "school". These Subjects are not easy to provide for in "City-as-School". Tethers monitor the progress of the students, 80 to 85% of the students go to college (or university, ms it is called in Britain) .after their time at "City-as-School". The success rate is high. And the students are enthusiastic about their "school". They like the responsibility of their work, and the sense of purpose it gives them. When the students leave "City-as-School", they don’t have a normal academic education; but they do know a lot about different kinds of work in the city! Which of the following is NOT included in permission of entering the "school"
What is color Why do some objects look red, others green, still others blue Color is caused by (11) light rays. We see color because objects reflect light. Something that is red reflects (12) red light. It reflects a little green or blue light, too, but we do not see it. In the same way, a green object reflects mostly green light. White objects reflect (13) of light. Black objects do not reflect any light. What happens to the colors of light that are not reflected They are absorbed by the object. The (14) the color, the less light is reflected and the more light is absorbed. Light that is absorbed is (15) heat. For this reason, dark-colored clothes are warmer in the sunlight than lighter-colored clothes.
