摘要：50．The passage is mainly about . A．a cheap way to get energy B．the location of recycling plants C．new ways of recycling wastes D．the probability of city environment D The North and South poles are remote and freezing places that receive lots of animal visitors but few human tourists. But even if you never plan to visit the polar bears in the north or penguins in the south, now is a perfect time to start thinking about them. That’s because 2007 marks the beginning of the International Polar Year (IPY), a two-year-old activity of science projects that aim to show how important the poles are to the health of our planet. During the IPY, which will last until March 2009, thousands of researchers from more than 60 countries will conduct more than 200 projects and expeditions to both the top and bottom of the world. In recent years, the polar regions have begun to change severely as a result of global warming. Temperatures there are rising faster than anywhere else on Earth. As a result, the ice and snow in these regions are melting at record-setting rates. One result is that sea levels are rising around the world, putting animals and people at risk. Only by studying the poles, say IPY researchers, can we find ways to protect them and ourselves. Both the Arctic and the Antarctic and cold and remote, but the two regions have important differences. For one thing, the Arctic is an ice-covered ocean surrounded by land. The Antarctic, on the other hand, is a continent of ice-covered land surrounded by water. Most polar studies have focused on the Arctic, and that is where scientists have observed the most remarkable changes in the ice. During a typical year, Arctic ice expands in the winter and shrinks in the summer. But recently, the amount of ice covering the ocean has been steadily dropping in both seasons.

　　With fifteen years Britain and 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(磁铁), 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．

With fifteen years Britain and other nations should be well on with the building of huge industrial complexes(联合体) of the recycling of waste. The word “rubbish” could lose its meaning because everything that 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 many 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 way 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（磁铁）, 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-size 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.

A．To deal with wastes in a better way.

B．To protect the environment from pollution.

C．To get raw materials locally.

D．To make much money from those plants.
