题型描述: 阅读理解Harvard, Princeton, Yale, Stanford, Columbia: These schools have a lot in common. Their admissions are incredibly competitive, they charge a high price and graduates have a big advantage in finding a good job. In fact, graduates from famous schools might not enjoy as much of an advantage in the job markets as many think, and that a big name on your diploma doesn’t always mean a big payoff. Let’s start with the cost: Tuition at the top schools can easily average $35,000 per year or more, while a lesser-known school might cost up to $ 20,000 areas so students have to add their living costs to their tuition bill. Once they graduate, however, students are often facing with thousands of dollars of debt that they need to repay. The reasoning goes that graduates from big-name schools can write their own ticket, but the statistics don’t bear this out. Graduates from a school which requires test scores high above the average can expect to make an extra 5％ more than others, but that doesn’t justify paying 40％ more for tuition. Graduating from a lesser-known school with the same academic qualifications can make you the same money over the long run. Long-range studies show experience and performance eventually matter much more than the name on your degree, especially when times get tough.1.Big-name universities are NOT famous for their _ _ _ _ _ _ .A. high tuitionB. fameC. competitivenessD. financial aid2.Graduates from famous schools _ _ _ _ _ _ get jobs with good pay.A. alwaysB. donˊt alwaysC. neverD. rarely3.The tuition of the famous schools averages _ _ _ _ _ _ per year.A. $ 20,000B. $ 30,000C. $ 35,000D. $ 25,0004.Managers today prefer to hire people with _ _ _ _ _ _ .A. much moneyB. a big-name diplomaC. experienceD. good fame5.If someone writes his own ticket, he _ _ _ _ _ _ A. is in troubleB. has a lot of choicesC. is very importantD. is good at writing专科英语I
