In today’s throw away society, dealing with the city’s growing mountain of waste is an inereasing challenge for the city countil(市议会)。

Recently. Edinburgh is faced with the problem of dssposing of(处理)about250,000

Million tons of waster a year . Despite different ways to dispose of much of it in a green manner---largely through encouraging tecycling---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 waster are to hr disposed of. The five councils (Edinburgh. East Lothian. West Lothian. Midlethian and Borders) face fine around $18million a year from 2013 it they don’t inerease recycling levels and rely less on landfill. With this in mind, the coumlls got together with the idea of building a lage incinerator plant (垃圾焚烧厂)to burn half of the waste produced in their districts. But the 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 wast by train to a landfill site near Dunbar, offered an alternative soution 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 eth council with a problem. By 2013,only50%of 1995 levels of waste will benllewed to be sent to landfill. Even if recveling large are met, there will still be a large amount of rubbish to be burnt up. Due build an Edinburgh and Midlothian councils have now decided to work together to build an ineinerator plant as time to find a solution is fast running out.

The subway system in the U.S. city of Boston will soon be equipped with train cars "Made in China," which will be shipped to the city in December. The current train cars in Boston have been running for decades and are too old to provide a modern trip experience.

Made in northeastern China's Jilin Province, the new cars can run at a speed of 102 kilometers per hour. Although designed according to the U.S. standard, the producing method of the cars is owned by a Chinese company named CRRC, the China Railway Rolling Stock Corporation. The final products match the Boston subway's strict maximum weight requirement of 34 tons per car, which barred a lot of world-famous companies from getting the order form. "The cars have to be solid, but light-weight at the same time," technology manager of the project Hong Haifeng told CCTV's Mandarin news channel. "And they have to be compatible with the century-old facilities in Boston."

This is the first time for Chinese rail equipment to be used in the United States. The new cars are designed to run for 30 years. CRRC showcased the model car in Boston on April 3. CCTV reported that the model was praised by the local leaders and citizens, including the governor of Massachusetts Charlie Baker. "We're really looking forward to putting these in transit," he said, adding that the upgrades will bring the Boston subway into the modern era.

1.Why Boston choose train cars made in China?

A. They can offer the local people a modern trip experience.

B. They can run at a higher speed.

C. They meet the Boston subway's strict requirements.

D. They are of higher quality.

2.What does the underlined phrase "be compatible with" in paragraph two mean?

A. match B. compare C. be competitive with D. be competent of

3.What's the attitude of the local people towards the model car?

A. negative B. doubtful C. skeptical D. optimistic

4.What may be the best title for the text?

A. Boston Will Replace Its Old Train Cars

B. The Advantages of Train China-made Cars

C. China-made Train Cars Will Come Into Boston

D. Bostonians' Preference for China-made Products

We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.

Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保温瓶),"said housing developer Brendan O’Neill."You have insulation(隔绝) everywhere, and it’s basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There’s insulation completely surrounding the building. We make it as sealed as possible."

A 147-square-meter passive house, presented by O’Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it’s set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O’Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事业) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.

While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.

However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."

1.Why aren’t ordinary family homes energy-efficient?

A. Building them wastes much energy.

B. Their energy mainly goes to heating and cooling.

C. Their sealing performance is poor.

D. They have no insulation around at all.

2.What is the feature of a passive house?

A. There’re no windows or chimneys.

B. There’s little space to place furniture.

C. Its building cost is relatively high.

D. It takes about four weeks to build one.

3.What’s David Peabody’s attitude to the future of the passive house?

A. Cautious.        B. Optimistic.        C. Skeptical.        D. Concerned.

The U.S. Postal Service (USPS) continues to be in the red. It reported a net loss of $5.6 billion for 2016 alone, the 10th straight year its expenses have exceeded revenue. Meanwhile, it has the debts of more than $120 billion, mostly for employee health and retirement costs. There are many bankruptcies. Fundamentally, the USPS is in a historic squeeze between technological change that has permanently decreased demand for its bread-and-butter product, and a regulatory structure that denies management the flexibility to adjust its operations to the new reality.

Interest groups ranging from postal unions to postcard makers exert self-interested pressure on the USPS’s final supervisor—Congress (参议院), insisting that whatever else happens to the Postal Service, aspects of the present legal situation they depend on get protected. This is why repeated attempts at reform legislation (立法) have failed in recent years, leaving the Postal Service unable to pay its bills except by postponing vital modernization.

Now comes word that everyone involved—Democrats, Republicans, the Postal Service, the unions and the systems heaviest users—has finally agreed on a plan to fix the system. Legislation is moving through the White House that would save USPS an estimated $28.6 billion over five years, which could help pay for new vehicles, among other survival measures. Most of the money would come from a penny-per-letter permanent rate increase and from shifting postal retirees into Medicare. The latter step would largely reduce the financial burden of annually pre-funding retiree health care, thus addressing a long-standing complaint by the USPS and its union.

If it clears the White House, this measure will still have to get through the Senate—where someone is bound to point out that it amounts to the bare, bare minimum necessary to make the Postal Service stay afloat, not comprehensive reform. There’s no change to collective bargaining at the USPS, a major mistake considering that personnel accounts for 80 percent of the agency’s costs. Also missing is any discussion of getting rid of Saturday letter delivery. That common-sense change enjoys wide public support and would save the USPS $2 billion per year. But postal special-interest groups seem to have killed it, at least in the White House. The emerging consensus around the bill is a sign that legislators are getting frightened about a politically embarrassing short-term collapse at the USPS. It is not, however, a sign that they’re getting serious about transforming the postal system for the 2lst century.

1.The financial problem with the USPS is caused partly by ________.

A.its rigid management. B.its unbalanced budget.

C.the cost for technical innovation D.the suspension of bank support.

2.It can be inferred from the passage that ________.

A.protecting every interest group benefits the USPS

B.the USPS will invest more money in retiree health care

C.the White House has already approved the reform

D.the author seems to be discontent with legislators

3.What does the underlined words “stay afloat” mean in Paragraph 4?

A.Boom. B.Survive.

C.Decline. D.Expand.

4.Which of the following is probably the best title for the text?

A.The USPS Starts to Miss Its Good Old Days

B.The USPS Starts to cooperate with Legislators

C.The USPS Needs Comprehensive Aid and Reform

D.The USPS Is Bound to Get out of the Dilemma

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans,  killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.

The 16-­year ­old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute,

has discovered a way to make plastic bags degrade(分解) in as few as 3 months, a finding that won him first prize at the Canada－Wide Science Fair, a $10 000 prize, a $20 000 scholarship, and a chance to revolutionize a major environmental issue.

Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

With this goal in mind, he ground plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.

The inputs are cheap: maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” said Daniel Burd.

1.Daniel Burd won first prize at the Canada－Wide Science Fair because________.

A. he found a new kind of microorganism

B. he contributed much to environmental protection

C. he found a way to degrade plastics in shorter time

D. he could encourage microbes growth in an easier way

2.Daniel Burd exposed one plastic sample to dead bacteria to ________.

A. make the live bacteria work better

B. test how effective his method was

C. know which bacteria worked faster

D. control the temperature in the process

3.Maintaining the required temperature takes little energy because ________.

A. plastics can get hot easily

B. microbes can produce heat themselves

C. much carbon dioxide is produced

D. the temperature can be controlled

4.Daniel Burd got his idea from ________.

A. his school textbook           B. the failure of researchers

C. his everyday work            D. the practice of other people
