/ 8 得分 第五题、将读下面的2篇阅读，并为每道题选择唯一正确的答案。（每小题2分，共20分） Questions 1 to 5 are based on the following passage. America's education system has become less a ladder of opportunity than a structure to transmit inequality from one generation to the next. That's why school reform is so critical. This is an issue of equality, opportunity and national conscience. It's not just about education, but about poverty and justice. It's true that the main reason inner-city schools do poorly isn't teachers' unions, but poverty. Southern states without strong teachers' ，unions have schools at least as awful as those in union states. Some Chicago teachers seem to think that they shouldn't be held accountable until poverty is solved. There are steps we can take that would make some difference, and Mayor Rahm Emanuel is trying some of them—yet the union is resisting. I'd be sympathetic if the union focused solely on higher compensation. Teachers need to be much better paid to attract the best college graduates to the nation's worst schools. But, instead, the Chicago union seems to be using its political capi
tal primarily to protect weak performers. There's solid evidence that there are huge differences in the effectiveness of teachers. The gold standard study by Harvard and Columbia University scholars found that even in high-poverty schools, teachers consistently had a huge positive or negative impact. Get a bottom 1% teacher, and the effect is the same as if a child misses 40% of the school year. Get a teacher from the top 20%, and it's as if a child has gone to school for an extra month or two. The study found that strong teachers in the fourth through eighth grades raised the skills of their students in ways that would last for decades. Just having a strong teacher for one elementary year left pupils a bit less likely to become mothers as teenagers, a bit more likely to go to college and earning more money at age 28. How does one figure out who is a weak teacher? Yes, that's a challenge. But researchers are improving systems to measure a teacher's performance throughout the year, and, with three years of data, ifs usually possible to tell which teachers are failing.
/ 8 Unfortunately, the union in Chicago is insisting that teachers who are laid off—often for being ineffective—should get priority in new hiring. That's an insult to students. Teaching is so important that it should be like other professions, with high pay and good working conditions but few job protections for bottom performers. This isn't a battle between garment workers and greedy bosses. The central figures in the Chicago schools strike are neither strikers nor managers but 350,000 children. Protecting the union demand sacrifices those students, in effect turning a blind eye to the injustice in the education system. 1. What do we learn about America's education system?（B） A) It provides a ladder of opportunity for the wealthy. B) It contributes little to the elimination of inequality. C) It has remained basically unchanged for generations. D) It has brought up generations of responsible citizens. 2. What is chiefly responsible for the undesirable performance of inner-city schools?（B） A) Unqualified teachers. C) Unfavorable learning environment. B) Lack of financial resources. D) Subconscious racial discrimination. 3. What does the author think the union should do to win popular support?（C） A) Assist the city government in reforming schools. C) Demand higher pay for teachers. B) Give constructive advice to inner-city schools. D) Help teachers improve teaching. 4. What is the finding of the gold standard study by Harvard and Columbia University scholars?（D） A) Many inner-city school teachers are not equal to their jobs. B) A large proportion of inner-city children often miss classes. C) Many students are dissatisfied with their teachers. D) Student performance has a lot to do with teachers. 5. Why does the author say the Chicago unions demand is an insult to students?（A） A) It protects incompetent teachers at the expense of students. B)
It underestimates students, ability to tell good teachers from poor ones. C) It makes students feel that they are discriminated against in many ways. D) It totally ignores students，initiative in the learning process. Questions 6 to 10 are based on the following passage. 装 订 线 装 订 线 装 订 线 装 订
/ 8 Air pollution is deteriorating in many places around the world. The fact that public parks in cities become crowded as soon as the sun shines proves that people long to breathe in green, open spaces. They do not all know what they are seeking but they flock there, nevertheless. And, in these surroundings, they are generally both peaceful and peaceable. It is rare to see people fighting in a garden. Perhaps struggle unfolds first, not at an economic or social level, but over the appropriation of air, essential to life itself. If human beings can breathe and share air, they don't need to struggle with one another. Unfortunately, in our western tradition, neither materialist nor idealist theoreticians give enough consideration to this basic condition for life. As for politicians, despite proposing curbs on environmental pollution, they have not yet called for it to be made a crime. Wealthy countries are even allowed to pollute if they pay for it. But is our life worth anything other than money? The plant world shows us in silence what faithfulness to life consists of. It also helps us to a new beginning, urging us to care for our breath, not only at a vital but also at a spiritual level. The interdependence to which we must pay the closest attention is that which exists between ourselves and the plant world. Often described as "the lungs of the planet", the woods that cover the earth offer us the gift of breathable air by releasing oxygen. But their capacity to renew the air polluted by industry has long reached its limit. If we lack the air necessary for a healthy life, it is because we have filled it with chemicals and undercut the ability of plants to regenerate it. As we know, rapi deforestation combined with the massive burning of fossil fuels is an explosive recipe for an irreversible disaster. The fight over the appropriation of resources will lead the entire planet to hell unless humans learn t share life, both with each other and with plants. This task is simultaneously ethical and political because can be discharged only when each takes it upon herself or himself and only when it is accomplished together with others. The lesson taught by plants is that sharing life expands and enhances the sphere c the living, while dividing life into so-called natural or human resources diminishes it. We must come t view the air, the plants and ourselves as the contributors to the preservation of life and growth, rather than a web of quantifiable objects or productive potentialities at our disposal. Perhaps then we would finally begin to live, rather than being concerned with bare survival. 6. What does the author assume might be
the primary reason that people would struggle with each other（A）
/ 8 A. To get their share of clean air. B. To pursue a comfortable life. C. To gain a higher social status. D. To seek economic benefits. 7. What does the author accuse western politicians of ?（D） A. Depriving common people of the right to clean air. B. Giving priority to theory rather than practical action. C. Offering preferential treatment to wealthy countries. D. Failing to pass laws to curb environmental pollution. 8. What does the author try to draw our closest attention to?（B） A. The massive burning of fossil fuels. B. Our relationship to the plant world. C. The capacity of plants to renew polluted air. D. Large-scale deforestation across the world. 9. How can human beings accomplish the goal of protecting the planet according to the author?（D） A. By showing respect for plants. B. By preserving all forms of life. C. By tapping all natural resources. D. By pooling their efforts together. 10. What does the author suggest we do in order not just to survive?（C） A. Expand the sphere of living. B. Develop nature's potentials. C. Share life with nature. D. Allocate the resources. 得分 第六题、写作。（20分） In recent years,“Wechat”is becoming increasingly popular. Many people express themselves, exchange ideas and deliver information by Wechat.
