Passage OneWe find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched.We feel that there are many disadvantages in streaming( 把…按能力分班)pupils.It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child.After all, it can be quite discouraging to be at the bottom of the top grade!Besides, it is rather unreal to grade people just according to their intellectual ability.This is only one aspect of their total personality.We are concerned to develop the abilities of all our pupils to the full, not just their academic ability.We also value personal qualities and social skills and we find that mixed-ability teaching contributes to all these aspects of learning.In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to cooperate, to share, and to develop their leadership skills.They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively.The pupils learn from each other as well as from the teacher.Sometimes the pupils work in pairs;sometimes they work on individual tasks and assignments, and they can do this at their own speed.They also have some formal class teaching when this is appropriate.We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently.An advanced pupil can do advanced work;it does not matter what age the child is.We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.21.In the passage the writer's attitude towards "mixed-ability teaching" is ( ).A. criticalB. questioningC. approvingD. objective

1.Resources can be said to be scarce in both an absolute and relative sense: the surface of the Earth is finite, imposing absolute scarcity; but the scarcity that concerns economists is the relative scarcity of resources in different uses. Materials used for one purpose cannot at the same time be used for other purposes; if the quantity of an input is limited, the increased use of it in one manufacturing process must cause it to become less available for other uses.The cost of a product in terms of money may not measure its true cost to society. The true cost of, say, the construction of a supersonic jet is the value of the schools and refrigerators that will never be built as a result. Every act of production uses up some of society’s available resources; it means the foregoing of an opportunity to produce something else. In deciding how to use resources most effectively to satisfy the wants of the community, this opportunity cost must ultimately be taken into account.In a market economy the price of a good and the quantity supplied depend on the cost of making it, and that cost, ultimately, is the cost of not making other goods. The market mechanism enforces this relationship. The cost of, say, a pair of shoes is the price of the leather, the labor, the fuel, and other elements used up in producing them. But the price of these inputs, in turn, depends on what they can produce elsewhere—if the leather can be used to produce handbags that are valued highly by consumers, the prices of leather will be bid up correspondingly.(5分)1.1 What does this passage mainly discuss?____(1分)A. The scarcity of manufactured goods.B. The value of scarce materials. C. The manufacturing of scarce goods.D. The cost of producing shoes.
