4.Recent research had claimed that an excess of positive ions (离子) in the air can have an ill-effect on people's physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charges. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens.When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea (恶心) or even mental disturbance. Animals are also found to be affected, particularly before earthquakes; snakes have been observed to come out of hibernation(冬眠), rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in all effort to foresee such disasters before they hit vulnerable areas such as California.Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.To increase the supply of negative ions indoors, some scientists recommend the use of ionizers : small portable machines which generate negative ions. They claim that ionizers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment.After all, it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.According to the passage, static electricity can be caused byA.using home-made electrical goods.B.wearing clothes made of natural materials.C.walking on artificial floor coverings.D.copying TV programs on a computer.

    Practice 8  You should spend about 40 minutes on this task.  Write about the following topic:  Some people think people have benefited from modern communications technology, but other people think some people have not benefited at all. To what extent do you agree or disagree?  You should write at least 250 words.

    正确答案: 【参考范文】
    Daily communication tools make the distance between people shrink. There are various ways such as mobile phones, Facebook, Twitter and E-mail which changes our life from daily life to work style. As for the dramatic and rapid changes, people in all walks of life hold different opinions. Personally, it is a must to be tolerant of the new technological innovations.
    It is undeniable that all these high-tech tools can alienate the virtual interpersonal relationship that exists between people. If we want to tell somebody something, we do not have to really see him, and we can send a short message, a E-mail, or leave one on Facebook. Regardless of the convenience, face-to-face conversations are still one of the best ways to understand each other.
    High technologies provide us with more choices which can yield higher efficiency, which can be illustrated from three perspectives. Firstly, it is a useful time-saver for people greatly enjoy social life. Social network enable them to spare the trouble of heavy traffic in rush hours when they need to have contact with friends. Secondly, it is also a money-saver. Compared with the high cost of an official visit to someone or some place, chatting on-site or through telephone is much cheaper. If each company has an E-conference system, information sharing should never be a daydream in the era of information. Lastly, and most importantly, with the great help of new inventions, people may communicate with others without being limited to geographical difference. Namely, no matter where one stays, he or she can get in touch with people on the Internet at any time.
    In summary, modem technologies are excellent assistants of our life and work, so it is wise to accept them and make full use of them properly.

    问答题
    Some people think that parents should plan their children's leisure time carefully. Others believe that children should decide for themselves how to spend their free time. Which opinion do you agree? Write a composition of about 400 words to state your view.

    正确答案:
    Childhood is a decisive period in the process of one's growth. Therefore, many people think that parents should carefully plan not only their children's school education but also their spare time. Other people, however, argue that children should have the freedom to plan their own extracurricular life. On balance, I would side with those parents who respect children's freedom and independence.
    If children have the freedom to make decisions on how to spend their spare time and develop their interests, they will gradually form a sense of responsibility and become more capable in the world. Take myself as a good example. My parents are like good teachers and helpful friends in my life. As I remember, they never excessively interfered with my life and always left enough freedom to me so that I could embark upon what I liked to do in my spare time. They quite understood that my weekdays were occupied with a heavy workload, and that only in my spare time I could have a change of pace. Meanwhile, although mutual understanding and tolerance were an important part of my childhood life, in no way does it mean that they spoiled me. They were austere teachers when I made mistakes, and helpful friends when I came across difficulties. Owing to their understanding, tolerance, guidance, and above all, love, I have grown up to be a person of self-confidence, optimism, and independence, ready to meet any challenges in my life. Without the free family environment that my parents carefully designed for me, I wouldn't have lived such a happy life.
    On the contrary, some parents expect too much of their children, depriving them of all their independence and freedom. These parents would rather sacrifice their children's interests and happiness for nothing but good scores, thus resulting in serious misunderstanding between parents and children. Some parents even went so far as to plan their children's schedule, filling every minute with study task. In this ease, children are deprived of happiness because they are bound hand and foot by endless homework, numerous exams and boring evening or weekend classes. Furthermore, having no freedom to plan their own life, these children are more likely to become introvert, heavily dependent on their parents when they grow up. This will definitely affect their growth. For one thing, since they have no opportunity to develop their independent thinking and explore their potential, they will find it very difficult to adjust themselves to the competitive society. For another, confining them in an ivory tower will make it hard for them to communicate with others. This will affect their career development in the future because the communication between people plays a major role in the workplace, and is one of the most important elements in achieving career success. Obviously, parents' excessive interference with children's after-school life, if carried to the extreme, can cause serious damage to both their happy childhood and their career in the future.
    To sum up, I believe that parents should leave enough freedom and privacy to their children with a view to cultivating their character. As long as parents allow their children the necessary freedom accompanied by careful guidance, their children will grow up to be independent, responsible and successful.

  • 第16题:

    资料:Faces, like fingerprints, are unique. Did you ever wonder how it possible for us to recognize people? Even a skilled writer probably could not describe all the features that make one face different from another. Yet a very young child or even an animal, such as a pingeon can learm to recognize faces. We all take this ability for granted.
    We also tell people apart by how they behave. When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.
    Like the human face human personality is very complex. But describing someone’s peronality in words is somewhat easier than describing his face. If you were asked to describe what a nice face looked like, you probably would have a difficult time doing so. But if you were asked to describe a nice person, you might begin to think about someone who was kind, considerate friendly, warm, and so forth.
    There are many words to describe how a person thinks, feels and acts. Gordon Allports, an American psychologist, found nearly18,000 English words characterizing differences in people’s behavior. And many of us use this information as a basis for describing or typing, his personality. Bookworms, conservatives, military types——people are described with such terms.
    People have always tried to type each other. Actors in early Greek drama wore masks to show the audience whether they played the villain’s or the hero’s role. In fact, the words person and persoality come from the Latin persona, meaning mask. Today, most television and movie actors do not wear masks. But we can easily tell the good guys from the bad guys because the two types differ in appearance as well as in actions.

    What is the main idea of this passage?

    A.How to describe people’s personatities
    B.How to distinguish people’s faces
    C.How to distinguish people both inward and outward
    D.How to differ good people from bad people

    答案:C
    解析:
    本题考查的是主旨理解。
    【关键词】main idea
    【主题句】第一段Faces, like fingerprints, are unique.(脸就像指纹一样独一无二。);Yet a very young child-or even an animal, such as a pigeon --- can learn to recognize faces. We all take this ability for granted.(然而,一个非常小的孩子或者一个动物(比如企鹅),他们能学会识别面容。);第二段We also tell people apart by how they behave. When we talk about someone’s personality, we mean the ways in which he or she acts, speaks, thinks and feels that make that individual different from others.(我们也可以通过举止来区分不同的人。当谈到某个人的个性时,我们指的是他或她的行为,说话,思考和感受,这些能让个体区别与他人。);最后一段But we can easily tell the good guys from the bad guys because the two types differ in appearance as well as in actions.(但我们能轻松地区别好人和坏人,因为这两种人在外貌和行为上都有不同之处。)
    【解析】第1题问“这篇文章的主要内容是什么?”。首先,第一段指出外貌是区分个体和其他之间差异的重要指标,而这种识别面容的能力在小孩子,甚至是动物身上都能找到。而在第二段,文章提到除了外貌,还可以通过个性举止来识别一个人。此外,在文章结尾,作者提到了区别好人坏人的方法,既可以通过观察外貌,也可以通过行为来判断此人是好是坏。所以C选项“如何从内在和外在来区分一个人”,把原文内容进行总结归纳,应为正确答案。A选项“如何描述人们的个性”,该选项只在第三段最后一句有提及“But if you were asked to describe a nice person, you might begin to think about someone who was kind, considerate(体贴的), friendly, warm, and so forth.”局部信息不能作为全文主旨;B选项“如何区分人脸”,文中并未提及,故排除;D选项“如何区分好人坏人”,该选项只在文章最后一句提及,全文并未多处涉及。

    Practice 2  You should spend about 40 minutes on this task.  Write about the following topic:  In countries where there is a high rate of unemployment, most pupils should be offered only primary education. However, others believe that higher education helps people find jobs. Discuss both sides and give your own opinion.  You should write at least 250 words.

    正确答案: 【参考范文】
    Being faced with a high rate of unemployment, many people begin to doubt the role or the purpose of receiving education, as high degree is not a stepping-stone to a successful career. Some people believe that a basic education can be enough to meet demands of job market and fulfill the requirements of a person's lifetime. However, others hold an opposite perspective on this issue. As far as I am concerned, unemployment has nothing to do with education itself, which is just not consistent with demands.
    First of all, when it comes to basic education, it has at least obvious advantages: On the on hand, it is primary education that establishes the foundation of all subjects one should master, which can be frequently used in daily life. Moreover, only learning from the very basic level, one may have the chance to get to know something deeper in the future. On the other hand, and more importantly, through primary education, one can cultivate his desire and interest of learning. Without the interests in study, it is impossible for anyone to promote himself to higher levels. Like the foundation of a building, primary education is the foundation to build one's life education upon.
    Furthermore, further education has its unique benefits: firstly, one can get the whole picture of a particular subject from higher education in college, which can benefit one's life constantly. Secondly, Uplifting one's life quality asks for two important elements: wealth and taste, which can be both gained from further education.. In other words, one can be a comprehensive person, not only learning his major, but also enjoying literature, art and music.
    Lastly, it is a fantastic chance to meet and talk with people who share something in common in higher levels of education. Universities are like a stage or platform, on which people can consolidate the friendship they have for one another.

    问答题
    The world of work is changing rapidly. Working conditions today are not the same as they used to be, and people no longer devote their life to doing one job for life. Write a composition of about 400 words to discuss the possible causes of these changes, and give your suggestions as to how people should prepare for work in the future.

    正确答案:
    Vast changes are taking place in the world's labour market, so it comes as no surprise that people's views on occupations are no longer the same as before. Nowadays, many people are inclined to do one job in their lives, while others change their job frequently. How has this phenomenon come about? I believe there are several reasons.
    As we are ushered into a new era, the demand for labour has shifted its focus. In the past, companies only required their employees to be loyal and to follow the supervisors' instructions to the letter. But nowadays, employees with imagination and creativity are most welcome in the job market. Therefore, the employer is always happy to see new faces and fresh ideas.
    People's attitudes toward work have also altered. They tend to believe that each person has his talents in many fields. After they have devoted themselves to a particular area for a few years, they may be bored with what they have been doing all along, and would like to make endeavors in some other field for a change. Some of them assume that they can make more accomplishments in a new job, while others simply hunger for new challenges and adventures.
    Finally, the world itself is changing at a bewildering pace. Some professions flourish while others slump. And there are new professions emerging every day. Thus, spurred to adapt themselves to the new, ever-changing circumstances, people will have to acquire new knowledge and skills, so that they can work in new fields and make more money.
    However, there are also evident disadvantages to changing one's job frequently. Once you switch to a new profession, you have to start from scratch. For scientists, as well as engineers or doctors, long-term training is indispensable to their career. Job-hopping, therefore, is not practical for them. For people whose jobs need little special training, work experience means much more. Hopping to a new lob, they have to gather experiences in the new field from the very beginning.
    Taken as a whole, it is my conclusion that people living in the present IT era have to get fully prepared for what is drawing near. It will be advantageous if they can be open-minded enough to acquire various types of knowledge and skills, and get psychologically prepared for the swift changes occurring with each passing day.
