三、阅读理解（3道小题，共30分） &&&& Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in&& factories&& or loud music or other common sounds found at home and at work.&&&& A person only needs to hear the noise for little more than one second to be affected.&&&& An American scientist had found that using aspirin could increase the temporary hearing loss or damage from loud noise. He did an&& experiment,&& using&& a&& number&& of&& male students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, and then he tested&& their&& hearing&& ability.&& He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing&& loss was about twice as great.&&&& The scientist said millions of persons in the United States use much larger amounts of aspirin than were used in the study. He said these persons face a serious danger of suffering hearing loss from loud noises. 1. Doctors have long known that ______.
A) one’s hearing damage or loss has nothing to do with a loud noise
B) hearing damage or loss can be caused by extremely loud noises.

&&&& 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) competitiveness
B) high tuition
D) financial aid 2. Graduates from famous schools ______ get jobs with good pay.
C) donˊt always
D) rarely 3. The tuition of the famous schools averages ______ per year.
A) $ 35,000
B) $ 30,000
C) $ 25,000
D) $ 20,000

&&&& A team of archaeologists (考古学家) has gone to New Mexico to look for proof of one of the greatest stories of the 20th century: the UFO crash at Roswell.&&&& William Foleman, an archaeologist at the University of New Mexico, agreed to excavate (发掘) the site where the UFO supposedly crashed in 1947.&&&& What exactly happened on the site is unclear. In 1947, a young man discovered some debris (碎片) on the field. After investigating the crash, the US Army&& announced&& they had recovered a “fly disc”.&&&& Several hours later, an Air Force general announced that the crash was caused by a weather balloon again. The field was closed off for several&& days&& while&& the&& military cleaned up the site.&&&& Believers claim that the military found a crashed UFO, along with several dead bodies at the site. This story has inspired countless books, movies and TV&& shows,&& but&& no one has been able to find any evidence to support it.&&&& In 1997, the Air Force said the weather balloon story was made up and that the military was actually conducting a crash-test program with balloons.&&&& But Foleman isn’t so sure. While he says he’s “Still uncertain” about UFOs, he knows that “something happened in July 1947”. 1. Some people believe a UFO ______ at Roswell.
C) crashed
D) disappeared 2. An archaeologist went to the site to look for ______.
A) Answers
B) evidence
D) fossils 3. In 1947 some debris (残骸) was found ______.
