The bull paced 1._ the tree, dragging the heavy iron chain, which led to a groove (槽) in the bark (树皮). The groove 2._ (deep) over the years. Though for whatever reason, it did not kill the tree.3_ some years, the family took their bull away. They cut the chain, leaving the loop around the tree and one link 4._(hang) down.Then one year, agricultural catastrophe struck Michigan in 5._ form of Dutch elm disease. All of the elms lining the road leading to the farm became infected 6._ died. Everyone thought that the old elm would be the next. The farm owners considered 7._(go) the safe thing: pulling it out and chopping it up into firewood before it died. 8._ (amaze), the tree did not die.

Or, as a plant pathologists (病理学家) put it，“Life breaks us all, but afterwards, many of us are strongest at the broken places.”.2011山东卷 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 from more families like the Jacobses.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 wont 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.11According to Paragraph 1，why did the plan of the Jacobs family fail?AThe twins wasted too much money.BThe father was out of work.CTheir savings ran out.DThe family fell apart.12How did the Jacobses manage to solve their problem?A.
