Article: China needs to set absolute restrictions on greenhouse gas emissions if it is to fulfill its aim to set up a carbon market over the next five years, a cabinet office think tank said in a paper. "It is only under an absolute emissions cap that carbon emission permits will become a scarce resource and possess the qualities of a commodity," the State Council"s Development and Research Center said in a paper in Seeking Truth, a magazine published by the ruling party. China has traditionally baulked at the idea of emissions caps either on a regional basis or for industrial sectors, invoking a key Kyoto protocol principle that puts most of the burden of cutting green-house gases on developed countries. China, the world 's biggest emitter of greenhouse gases, has also been under external pressure to make stronger commitments in the battle against global warming .The country has been the biggest beneficiary of the Clean Development Mechanism, a UN-backed scheme that allows industrialized countries to meet their CO2 reduction targets by purchasing certified emission reductions or CERs from low-carbon projects launched in developing nations. However, the European Union, the biggest buyer of CERs, has said it will not accept CERs generated by Chinese projects once the first phase of its Emissions Trading Scheme ends in 2012, though projects already registered will remain valid. Question: How does the CER scheme work? - Countries can buy the right to produce as much carbon emissions as they like. - All countries are required to set a carbon emissions cap and can then get certificates on how developed their environmental programme is. - Developed countries are allowed to produce more emissions than industrial countries. - Developed countries can buy the right to produce more carbon emissions from developing countries that produce less.
Developed countries can buy the right to produce more carbon emissions from developing countries that produce less.

Read the following article and select the best answer. Article: A city child's summer is spent in the street in front of his home,and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing--not out of special cruelty, but because they took it for granted that I would be no good at it. They were right,of course. I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question;but whoever he was,I nod to him gratefully now. " What's in those books you're always reading?" he asked casually. "Stories," I answered. "What kind?"asked somebody else without much interest. Nor do I know what drove me to behave as I did,for usually I just sat there in silence,glad enough to be allowed to remain among them;but instead of answering his question,I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bugeyed and breathless. I must have told it well,but I think there was another and deeper reason that made them so keen an audience. Listening to a tale being told in the dark is one of the most ancient of man's entertainments,but I was offering them as well,without being aware of doing it,a new and exciting experience. The books they themselves read were the Rover Boys or Tom Swift or G.A. Henry. I had read them too,but at thirteen I had long since left them behind.... Question: The writer feels grateful even now to the boy who asked the question because the boy _ . - invited him to join in their game - liked the book that he was reading - broke the long silence of that summer evening - offered him an opportunity that changed his life
offered him an opportunity that changed his life

Q: Read the following article and select the best answer. Article: With fifteen years prefix = st1 /Britainand other nations should be well on with the building of huge industrial complexes for the recycling of waste . The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful . Even the most dangerous and unpleasant wastes would provide energy if nothing else . The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out . The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city . This plant would recycle not only metal such as steel , lead and copper , but also paper and rubber as well . Another new project is being set up to discover the best ways of sorting and separating the rubbish . When this project is complete , the rubbish will be processed like this : First , it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed ; then it will pass through a powerful fan to separate the lightest elements from the heavy solids ; after that founders and rollers will break up everything that can be broken . Finally , the rubbish will pass under magnets , which will remove the bits of iron and steel ; the rubber and plastic will then be sorted out in the final stage . The first full-scale giant recycling plants are perhaps fifteen years away . Indeed , with the growing cost of transporting rubbish to more distant dumps , some big cities will be forced to build their own recycling plants before long . Question: The passage is mainly about_. - a cheap way to get energy - the location of recycling plants - new ways of recycling wastes - the probability of city environment
A: new ways of recycling wastes
