“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 Diana.
The Smith family did work out a solution: They asked and received more aid from the school, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program.They will each graduate with a $20,000 debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to see more families like the Smiths.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.

Read the following passage and the statements that follow. Choose the best answer for each statement from the three choices marked A, B and C .
Outdoor Learning Environment
“How do they get the tomato on the vine(藤、蔓)？”
The question shocked Hillis. It reminded him of the time five years ago when he was volunteering at Beattie Elementary School in his daughter’s kindergarten classroom. He’d been reading the children a book about gardening.
“These kids had only seen vegetables in supermarkets,” he says. “I felt that something important was missing in their lives.”
So he went to work. Hillis and his wife, Sally, made the local government believe that it was necessary to create an outdoor learning environment. He and other volunteers raised more than 30,000 dollars to make such a project. The project was designed like the Platte River. Like the river, the school’s front walkway turns east to west, so they planted things along the walkway, such as native grasses which can be found along the river too.
Today, students are greeted every day by the cedar-mulched creation(雪松覆盖的表面), which spreads the length of three city blocks. In the back, there’s a garden, with twenty 1 ton rocks lying in the ground, where teachers hold classes.
The outdoor effort has changed things inside, too. For science, children plant seeds and, based upon each seed’s size and weight, guess how large a vegetable will grow to become. For arts and crafts, they collect fallen leaves and make designs out of them. Other science lessons make up a large part of the outdoor learning process. “No matter what time of the year it is,” Hillis says, “there’s always something going on.”
