Although the three great World Conferences of women were more concerned with recognizing and compiling approaches to emancipation we can currently confirm a general sharpening of awareness. It has become clear that the Third World cultures, in earlier times strongly matriarchal(母权制的), have been weakened in this respect by the methods of colonial education which are almost exclusively directed towards the male Of the many criticisms of this situation let one voice be heard: "Deve lopment education groups and programmes are very much male dominated and lack woman’ s perspective”.So,too, the hopes placed in vocational(职业的) training ocationalization"--as an aid to equality have been disappointed since this in its turn was to large extent focussed on the male. In these circums tances we should not be surprised that until now women have participated least in the educational processes which have been introduced. Only 20% at tend primary school and the percentage of those who leave early is highest among girls. Because of the lack of basic training only around 10% take part in Adult Education programmes. Hence it is vitally important to secure a turning point by increasing the awareness of the need for education. The International Conference at Jomtien in 1990 provided the solution to this: "A more educated mother raises a healthier family. she has fewer and better educated children. she is more productive at home and in the workplace and is better able to get further education". Many problems in school are consequences of incorrect or improperly balanced nutrition combined with inadequate hygiene(psE). Together these factors can lead to failure to keep pace in school Hence even Primary Education for girls should be directed towards the basic needs and necessities and provide answers which are as simple as possible. In rural districts such answers will be different from those given in urban areas. The education of girls and women must to a large degree be an education for the life they will lead, tailored to a womans position In saying this we are in fact demanding that the education of women, like all educational work in the third World, should be an integrated part of the community. Consequently there are many partners in this process school, family, small businesses, governmental and non governmental organizations.

In these circumstances we should not be surprised that until now women have participated least in the educational processes which have been introduced.Only 20% attend primary school and the percentage of those who leave early is highest among girls.Because of the lack of basic training only around 10% take part in Adult Education programmes.Hence it is vitally important to secure a turning point by increasing the awareness of the need for education.

Hence even Primary Education for girls should be directed towards the basic needs and necessities and provide answers which are as simple as possible.In rural districts such answers will be different from those given in urban areas.The education of girls and women must to a large degree be an education for the life they will lead,tailored to a woman′s position.In saying this we are in fact demanding that the education of women,like all educational work in the Third World,should be an integrated part of the community.Consequently there are many partners in this process school,family,small businesses,governmental and non governmental organizations.The educational skill consists in keeping this interplay active in such a way that there is no deficiency in material content.An important consequence of this is the awakening of the desire to question,which,on the one hand presses for further education and on the other for its practical application. From the passage it can be inferred that in the Third World _____ . A)the matriarchal culture was stronger in the past B)the methods of colonial education have made the matriarchal culture stronger than earlier times C)the matriarchal education is directed towards men D)the development education groups and programs lack male domination It is very important to be more aware of the need for education of women because _____ . A)women have at least participated in the educational processes
B)only 1/5 of girls can enter elementary school and most of them have to quit early C)only about 1/10 of women participate in continuing education D)so far very few girls and women take part in the educational processes The author's demand is that A)the education of women should be a process of community activity B)the education of women should be a part of community in which many partners are combined C)the education of women should be organizations run by government D)women should like all educational work in the Third World The best title of this passage is A)The Position and Role of Women in the Development of Education B)The Education of Girls and Women C)The Education of Women in the Third World D)Womens Education Groups and Program Most speakers are surprised to learn that people who speak only one language form a minority of the worlds population and that most people function in two or more languages. While few people are truly“ balanced" bilinguals(能使用两种语言的人) or polyglots who feel equally comfortable with all languages, the fact is that most of the word s population functions in more than one language. Given this, it s somewhat surprising that so much attention is paid in the English speaking world to the matter of learning an additional language. If so many people seem to do it so easily, then just what is the problem? The simplest answer is that there really isn t one Given ample opportunity and time, most people can learn as many languages as they want or need to. But as teachers charged with the responsibility of adding English to the linguistic inventory() of non English speaking children, we must be concerned with precisely these matters--providing ample and effective opportunity and using time as effectively as possible. This chapter will look briefly at how children become bilingual. First, we ll examine the conditions that lead to bilingualism in preschoolers, then we ll turn our attention to languange learning in the classroom. In focusing on the differences between language acquisition at home and at school, we ll see that there s the potential for conflict between childrens informal language learning in the home and the more formal experience of the school As teachers, we might well ask why it' s necessary to study second language learning in preschoolers Then school aged children are our ma jor concern. Obviously, we re primarily interested in how us to know something about the experience of younger children. The reason is simple--the bete or school aged children learn Engilish as an additional language. But it' s equally important we understand childrens previous successful experiences of learning, the better we can plan an effective language learning environment for children in school bilingualism and finally, the potential for conflict between the home and school experience. Which of the following statements is not true? A)A few people in the world speak only one language. B)Most people speak two or more languages. C)A minority of people can function in only one language. D)A majority of people can function in only one language The word"ample" in paragraph 2 means everything except A)substantial or suffcient B)insufficient or meagre C)abundant or plentiful D)more than is necessary The main idea of the chapter that this passage introduces is A)people who speak one language are the minority of the world's population B)most people can learn as many languages as they want or need to C)how children become two language learners at home and at school
B)only 1/5 of girls can enter elementary school and most of them have to quit early C)only about 1/10 of women participate in continuing education D)so far very few girls and women take part in the educational processes The author′s demand is that _____ . A)the education of women should be a process of community activity B)the education of women should be a part of community in which many partners are combined C)the education of women should be organizations run by government D)women should like all educational work in the Third World The best title of this passage is _____ . A)The Position and Role of Women in the Development of Education B)The Education of Girls and Women C)The Education of Women in the Third World D)Women′s Education Groups and Programs Passage 2 Most speakers are surprised to learn that people who speak only one language form a minority of the world′s population and that most people function in two or more languages.While few people are truly“balanced”bilinguals(能使用两种语言的人)or polyglots who feel equally comfortable with all languages,the fact is that most of the word′s population functions in more than one language.Given this,it′s somewhat surprising that so much attention is paid in the English speaking world to the matter of learning an additional language.If so many people seem to do it so easily,then just what is the problem?

Modern scientists believe that humankind, like other animals, evolved through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape)group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way. In other species evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe(k3i E)is marvelously adapted to, grazing on treetops but, as such, it is also specialized and thus restricted to grazing on tree and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is incapable of catching or eating other prey. The same is true for countless other species. or humankind the reverse is true. Our evolution had led to a very generalized capability. Our highly developed intelligence and ability to make and handle tools mean that we can do virtually anything Rather than evolving into a specialized role in balance with natural enemies, competitive species and environmental factors, humans evolved in such a way that we are capable of moving into every environment on Earth and even into space. No natural predator or competitor offers significant resistance, and other natural enemies such as disease have been substantially controlled Said another way, we see in humankind a tremendous imbalance between biotic(生命的:生物 a,)potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities. From the passage we can infer that A)the evolution of humankind is very important to earlier species B)during the process of the evolution humankind changed a lot and got used to the environment gradually C)human beings are similar to other creatures in a unique way D)the evolution of humankind differs from that of other species because it was through millions of years of change Which of the following statements is true? A)Different species cannot adapt to the same environment because they have different abilities. B)Different species are specialized because they are in different places in the environmental structure ")Specialization of different species in abilities and places in the environmental structure result from evolution D)The giraffe is specialized in grazing on treetops because it is restricted to eating ants Humans can practically do anything because A)they have evolved into a specialized role in balance with natural enemies B)they are able to move into every environment on Earth and even in Space C)they are so evolved that they can control other natural enemies as well as disease D)their intelligence and ability to produce and use tools are developed greatly
D)our chief concern is school aged children in terms of second language learning The order of the following parts of this chapter will be _____ . A) home bilingualism,school bilingualism and the potential for conflict between the home and school experience B)learning in the classroom,bilingualism in preschoolers and the differences between language acquisition at home and at school C)the problem about learning an additional language,teachers′ responsibility of adding English to linguistic inventory and the necessity to study second language learning D)the surprise about the function of languages,the population related to language learning and the brief examination of the conditions leading to bilingualism Passage 3 Now let′s look ourselves as a species in relation to ecosystem balance.

Said another way,we see in humankind a tremendous imbalance between biotic(生命的；生物 的)potential and environmental resistance.The result is the rapidly increasing world population,frequently referred to as the population explosion.Further,to support our growing population,natural ecosystems are being increasingly displaced by human habitations,agriculture,and other human supporting activities. From the passage we can infer that A)the evolution of humankind is very important to earlier species B)during the process of the evolution humankind changed a lot and got used to the environment gradually C)human beings are similar to other creatures in a unique way D)the evolution of humankind differs from that of other species because it was through millions of years of change Which of the following statements is true? A)Different species cannot adapt to the same environment because they have different abilities. B)Different species are specialized because they are in different places in the environmental structure. C)Specialization of different species in abilities and places in the environmental structure result from evolution. D)The giraffe is specialized in grazing on treetops because it is restricted to eating ants. Humans can practically do anything because _____ . A)they have evolved into a specialized role in balance with natural enemies B)they are able to move into every environment on Earth and even in Space C)they are so evolved that they can control other natural enemies as well as disease D)their intelligence and ability to produce and use tools are developed greatly
The main idea of the last paragraph A)the population explosion is the result of amazing imbalance between biotic potenital and environmental resistance B)the rapid increase of the population is known as the population explosion C)humans have to destroy natural ecosystem in order to support themselves D)human habitations and agriculture are activities to support the rapidly growing population Passage 4 The technological revolution that will prevail for the reminder of this century will create jobs and professions that as little as five years ago were nonexistent.

Again it will be automation that will displace many of the low skilled and semiskilled workers in the present economy. In fact, the era of the paperless office has already begun. It has been promoted by two principa developments: computers that process business information and the explosive growth of telecommunications systems and products. This office revolution not only has changed how work i done and information is handled but has redefined the function of everyone who works in an ffice, from the corporate executive down to the lowliest clerk For the job hunter of 2020, scanning classified ads will be a quick education in how drastically the workplace will have changed.

Now, two U. S reports predict that it may happen sooner than we counted on. Released separately by the U.S. Environmental Protection Agency(EPA)and the National Research Council(NRC), the reports warn that the first effects may felt as early as the 1990s. a greenhouse can produce a tropical climate in sub zero weather by trapping the suns rays under glass. Scientists say we re creating the same effect on a global scale by burning fossil fuels(coal, oil, gas). Carbon dioxide is a by product of the burning. The gas allows sunlight to penetrate the atmosphere but slows the escape of heat back into space. This one way trip for the sun's rays tends to make our planet a big greenhouse. We are beginning to warm up, just like a pot of violets under gla We ve been burning fossil fuels for centuries. However the automobile and heavy industry have speeded up the release of carbon dioxide so much that experts say it' s almost too late to prevent the coming results. Even a switch to other forms of energy might do no more than de lay change A warming trend in climate will be the main effect. At first, that seems all to the good, especially for Canadians. But a closer look reveals dangers which may call for ma jor adjustments all over the world. Average temperatures may rise by 2c by the year 2040, and by 5c by 2100. Increases up to three times as large may take place at the poles, however, causing the ice caps to melt rapidly. The oceans would then rise, causing flooding of coastal cities such as Halifax To compensate a little, Halifax could have a climate like Daytona Beach, Florida, by 2100. Coastal cities will have to plan for coming changes. The loss of land, houses, and factories can be reduced by planning new building sites, erecting sea walls, and contouring(循等高线修筑)the land. Even so, low lying countries will suffer. One third of the Netherlands, Florida and ouisiana, and large parts of Bangladesh will be submerged. Many port cities will look like Venice. he warmer climate will bring changed patterns of drought and rainfall. The desert Sahel area of Africa will get more rain, but the wheat growing areas of the United States, the Soviet Union, and China will be drier and less productive. More carbon dioxide will likely spur plant growth, but me regions may become too hot and dry for crops Earth has gone through temperature swings before, but only slowly over thousands of years. The coming changes may take place in a mere 120 years, and the NrC report says they would have"few or no precedents in the Earths recent history. It is the global environment issue of the century ", says Henry Hengeveld of Environment Canada. For the first time man will change his environment on a global basis. Others like Jack Vallentyne, a senior Canadian water scientist, rank the greenhouse effect with nuclear war and the population explosion in terms of its potential impact on humans. In Canada, as elsewhere, some will gain and some lose from the greenhouse effect. The NRC report stresses that we need to learn a good deal more about the degree of temperature change, the timing, and the consequences before we jump in with costly plans which may turn out wrong In the first paragraph, the phrase "counted on"means A)hoped B)wished C D)accounted The "Greenhouse effect" is so called because A)fossil fuels are burnt in green houses B)a carbon dioxide is causing the Earth to warm up C)the worlds climate has become tropical by the penetration of the sunlight D)the sun's rays are trapped by the glass in the greenhouse
