2017年9月公共英语一级考试模拟真题及答案
【第一题】
Antarctica and Environment
Antarctica has actually become a kind of space station - a unique observation post for detecting important changes in the world‘s environment. Remote from major sources of pollution and the complex geological and ecological systems that prevail elsewhere， Antarctica makes possible scientific measurements that are often sharper and easier to interpret than those made in other parts of the world.
Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor， where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from the United States， Switzerland， and France are pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet - a concern they believe the world at large should share.
The Transantarctic Mountain， some of them more than 14，000 feet high， divide the continent into two very different regions. The part of the continent to the “east” of the mountains is a high plateau covered by an ice sheet nearly two miles thick. “West” of the mountain， the half of the continent south of the Americas is also covered by an ice sheet， but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disappeared， the western part of the continent would be reduced to a sparse cluster of island.
While ice and snow are obviously central to many environmental experiments， others focus on the mysterious “dry valley” of Antarctica， valleys that contain little ice or snow even in the depths of winter. Slashed through the mountains of southern Victoria Land， these valleys once held enormous glaciers that descended 9，000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone， perhaps a casualty of the global warming trend during the 10，000 years since the ice age. Even the snow that falls in the dry valleys is blasted out by vicious winds that roars down from the polar plateau to the sea. Left bare are spectacular gorges， rippled fields of sand dunes， clusters of boulders sculptured into fantastic shapes by 100-mile-an-hour winds， and an aura of extraterrestrial desolation.
Despite the unearthly aspect of the dry valleys， some scientists believe they may carry a message of hope of the verdant parts of the earth. Some scientists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.

B. 南极洲：地球最早的报警战。
C.南极洲：独一无二的观察哨。
D. 南极洲：神秘的地方。三项都是总内容众的组成部分。
2. D 大陆西部成为一群岛屿。第三段“横断南极的山脉， 有的高达一万四千多英尺，把这大陆分成情况各异的两个地区。山脉以东的大陆部分是由差不多两英里厚的冰层覆盖的高原;山脉以西，即美洲以南的半个大陆也为冰层所覆盖。可是，这里冰层覆盖在大大低于海平面的岩石。如果西南极洲冰层消失，那这大陆西部将成为稀疏的岛群。”

【第二题】
Contribution of Coeducation
Imagining being asked to spend twelve or so years of your life in a society which consisted only of members of own sex. How would you react? Unless there was something definitely wrong with you， you wouldn’t be too happy about it， to say the least. It is all the more surprising therefore that so many parents in the world choose to impose such abnormal conditions on their children - conditions which they themselves wouldn’t put up with for one minute!
Any discussion of this topic is bound to question the aims of education. Stuffing children’s heads full of knowledge is far from being foremost among them. One of the chief aims of educations is to equip future citizens with all they require to take their place in adult society. Now adult society is made up of men and women， so how can a segregated school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a shock.
A co-educational school offers children nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other， to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability， athletic achievement and many of the extra-curricular activities which are part of school life. What a practical advantage it is ( to give just a small example ) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense co-education makes of the argument that boys are cleverer than girl or vice-versa. When segregated， boys and girls are made to feel that they are a race apart. Rivalry between the sexes is fostered. In a coeducational school， everything falls into its proper place.
But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. Boys don’t grow up believing that women are mysterious creatures - airy goddesses， more like book-illustrations to a fairy-tale， than human beings. Girls don’t grow up imagining that men are romantic heroes. Years of living together at school dispel illusions of this kind. There are no goddesses with freckles， pigtails， piercing voices and inky fingers. There are no romantic heroes with knobbly knees， dirty fingernails and unkempt hair. The awkward stage of adolescence brings into sharp focus some of the physical and emotional problems involved in growing up. These can better be overcome in a co-educational environment. Segregated schools sometimes provide the right conditions for sexual deviation. This is hardly possible under a co-educational system. When the time comes for the pupils to leave school， they are fully prepared to enter society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.
1. What is the best title for this passage?
[A] only co-education can be in harmony with society.
[B] people are in great need of co-education.
[C] any form of education other than co-education is simply unthinkable.
[D] co-education has many features.
2. what does co-education offer to children?
[A] A society.
[B] A true small model of society.
[C] A real life.
[D] True version of social condition.
3. According to the passage， what is one of the chief aims of education?
[A] It is for students to acquire knowledge.
[B] It is to equip future citizens with scientific technology.
[C] It is to equip future citizens with what is required in getting a position in society.
[D] It is for students to get academic achievements.
4. Why do boys and girls in co-education have no illusion about each other?
[A] They live together and know each other too well.
[B] Years of living together at school dismiss such illusion.
[C] co-education encourage them to have an healthy attitude toward life.
[D] They are familiar with each other’s problems.

答案详解
1. C 除了男女合校，其他形式的教育简直难以想象。答案见第一段“设想请你在一个只有你一样性别的人存在的社会生活12年光景，你会如何反应呢?除非你本人确实有毛病，否则，你至少不会太高兴。因此，世界上有那么多的父母愿意把这种不正常的环境(他们自己一分钟都受不了的环境)强加给他们的孩子们，这太令人惊讶!”第二段讲“教育的目的之一就是为未来的公民在成人社会中找一席之地，准备好需要的一切。而社会由男女组成，那分校又怎能准备?”后两段讲合校之优点，分校之缺点，具体对比突出主题。这都说明C 最合适。
A. 只有合校才能和社会相协调。
D. 合校有许多特点。这两项文章内容涉及到，但作为最佳标题则不确切。
B. 人们非常需要合校。文内没有直接谈到。
2. B 一个真实社会的缩影。这在第三段第一句“男女合校确实能给孩子们提供一个社会真实的缩影。”下面的内容都是围绕这个主题而写的具体情况。如：生活在一起，彼此了解，对比等。
A. 社会。
C. 一种真实的生活。
D. 真实的社会情况。都没有B项那样确切。
3. C 为未来公民在社会上拥有一席之地，准备好所需要的一切。这在第二段“这个话题的讨论必然会引出教育目的的问题。把各种知识塞进孩子头脑远不是教育主要的目的，教育的主要目的之一是为未来公民在成人社会求得一席之地，准备好所需一切。”
A. 学生学到只是。
B. 以科技武装未来公民。
C.为学生缺德学术成就。都只是知识学习的一个部分。
4.B 几年学校共同生活打消了幻想。答案在第四段中，“在学校中，几年生活在一起消除这一类的幻想。没有什么脸上有雀斑，梳着鞭子，涂着指甲，尖的噪音的女神，也没有膝部有疙瘩，指甲脏兮兮，头发乱蓬蓬的浪漫英雄。棘手的青春期明显呈现出来的成长过程中身体上和感情上的问题，在男女合校环境中得到很好的解决。”
A. 他们生活在一起，彼此太了解。此答案太过，不是太了解而不产生幻想，而是了解情况;真人就在眼前，人就实际了，消除了幻想。
C. 合校鼓励他们对生活有一种健康积极的态度。这是合校的大方向，不是消除幻想的根本原因。
D. 他们熟悉彼此的问题。不全是消除幻想之因，而是处理问题的前奏。这在最后一段最后两句话有说明“当学生离校的时刻来到时，他们已是很有适应性的成人，为进入社会做好了充分准备。他们已有几年处理面临男女的许多问题的经验。”
