五、阅读理解
In 1993, New York State ordered stores to charge a deposit (定金) on beverage (饮料) containers.Within a year, consumers had returned millions of cans and glass and plastic bottles.Plenty of companies were eager to accept them as raw materials for new products.But because few could figure out what to do with the plastics, much of it was buried in landfills (垃圾填埋场)．The problem was not limited to New York.Unluckily, there were too few uses for second­hand pla stics.
Today, one out of five plastic soda bottles is recycled in the United States.The reason for the change is that now there are dozens of companies across the country buying discarded plastic soda bottles and turning them into fence posts, paint brushes, etc.
As the New York experience shows, recycling involves more than simply separating valuable materials from the rest of the rubbish.A discard remains until somebody fi­gures out how to give it a second life.Without adequate markets to absorb materials collected for recycling, throwaways actually depress prices for used materials.
Shrinking landfill space and rising costs for burying and burning rubbish are forcing local government to look more closely at recycling.In many areas, the East Coast especially, recycling is already the least expensive waste­management option.For every ton of waste recycled, a city avoids paying for its disposal, which, in parts of New York, amounts to saving more than $100 per ton.Recycling also stimulates the local economy by creating jobs and cuts down the pollution control and energy costs of industries that make recycled products by giving them a more refined raw material.
1．What regulation was issued by New York State concerning beverage containers?
A．Beverage companies should be responsible for collecting and reusing discarded plastic soda bottles.
B．Throwaways should be collected by the state for recycling.
C．A fee should be charged on used containers for recycling.
D．Consumers had to pay for beverage containers and could get their money back on returning them.
2．The returned plastic bottles in New York used to ________.
A．end up somewhere underground
B．be turned into raw materials
C．have a second­life value
D．be separated from other rubbish
3．The key problem in dealing w ith returned plastic beve­rage containers is ________.
A．to sell them at a profitable price
B．how to turn them into useful things
C．how to reduce their recycling costs
D．to lower the prices for used materials
4．Recycling has become the first choice for the disposal of rubbish because ________.
A．local governments find it easy to manage
B．recycling has great appeal for the jobless
C．recycling causes little pollution
D．other methods are more expensive
5．It can be concluded from the passage that ________.
A．rubbish is a potential remedy (补救) for the shortage of raw materials
B．local governments in the U．S.can expect big profits from recycling
C．recycling is to be recommended both economically and environmentally
D．landfills will still be widely used for waste disposal

四、阅读理解
Diana Jacobs thought her family had a workable plan to pay for college for her 21­year­old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing.Then her husband lost his job, and the plan fell apart.
“I have two kids in college, and I want to say ‘come home’， but at the same time I want to provide them with a good education，” says Jacobs.
The Jacobs family did work out a solution: they asked and received more aid from the schools, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program.They will each graduate with $20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to hear more families like the Jacobs.More students are applying for aid, and more families expect to need student loans.College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition (学费) continues to rise.A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%.Student borrowing has more than doubled in the last decade.
“If we go on this way for another 25 years, we won't have an affordable system of higher education，” says Patrick M．Callan, president of the center.“The middle class families have been financing it through debt.They will send kids to college whatever it takes, even if that means a huge amount of debt.”
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them.The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.
1．According to Paragraph 1, why did the plan of Jacobs family fail?
A．The twins wasted too much money.
B．The father was out of work.
C．Their saving ran out.
D．The family fell apart.
2．How did the Jacobs manage to solve their problem?
A．They asked their kids to come home.
B．They borrowed $20,000 from the school.
C．They encouraged their twin sons to do part­time jobs.
D．They got help from the school and the federal government.
3．Financial aid administrators believe that ________.
A．more families will face the same problem as the Jacobs
B．the government will receive more letters of complaint
C．college tuition fees will double soon
D．America's unemployment will fall
4．What can we learn about the middle class families from the text?
A．They blamed the government for the tuition increase.
B．Their income remained steady in the last decade.
C．They will try their best to send kids to college.
D．Their debts will be paid off within 25 years.
5．According to the last paragraph, the government will ________.
A．provide most students' scholarships
B．dismiss some financial aid administrators
C．stop the companies from making student loans
D．go on providing financial support for college students
