     In today's throw-away society, dealing with the city's growing mountain of waste is an increasing challenge

for the city council (市议会).

     Recently, Edinburgh is faced with the problem of disposing of (处理) about 250,000 million tons of waste

a year. Despite different ways to dispose of much of it in a green manner-largely through encouraging recycling-

its aging facilities such as the Powderhall landfill do not have the ability to deal with it.

     The European Union (EU) has issued a new policy, regulating how such mountains of waste are to be

disposed of. The five councils (Edinburgh, East Lothian, West Lothian, Midlothian and Borders) face fines

around £18 million a year from 2013 if they don't increase recycling levels and rely less on landfill. With this

in mind, the councils got together with the idea of building a large incinerator plant (垃圾焚烧厂) to burn half

of the waste produced in their districts. But this plan fell apart after the change of target levels by a new UK

government waste policy which required that no more than 25% of the city's waste should be disposed of in

this way by 2025.

     After the plan was abandoned, a private company which already transported millions of tons of the city's

waste by train to a landfill site near Dunbar, offered an alternative solution when it suggested opening a huge

waste site near Portobello.

     Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the Edinburgh

Council to accept the suggestion. But soon they turned it down-after 700 local objections reached them-because

it would have meant hundreds of lorries a day making loud noise through heavily populated areas.

     That still leaves the council with a problem. By 2013, only 50% of 1995 levels of waste will be allowed to

be sent to landfill. Even if recycling targets are met, there will still be a large amount of rubbish to be burnt up.

Due to this, Edinburgh and Midlothian councils have now decided to work together to build an incinerator plant

as time to find a solution is fast running out.

1. The main way of handling waste in a green manner in Edinburgh is _____.

A. recycling

B. restoring

C. burying

D. burning

2. The five councils worked out a plan to build an incinerator plant to _____.

A. reduce the cost of burying waste

B. meet the EU requirements

C. speed up waste recycling

D. replace landfill sites

3. The city council of Edinburgh rejected the suggestion to open a huge landfill site near Portobello because

    _____.

A. it came from a private company

B. the council was not interested in it

C. it was not supported by EU

D. the local people were against it

4. What is the final decision of Edinburgh and Midlothian Councils?

A. To open a new landfill nearby.

B. To close the Powderhall landfill in 2015.

C. To set up a plan for burning waste.

D. To persuade people to deduce their waste.
