The general frequency of colds continues to decline into adults.Elderly people who are in good health have as few as one or two colds annually.One exception is found among people in their twenties, especially women, who show a rise in cold infections(感染), because people to this age group are most likely to have young children.Adults who delay having children until their thirties and forties experience the same sudden increase in cold infections.
The study also found that economics (经济状况) plays an important role.As income increases, the frequency at which colds are reported in the family decreases.Families with the lowest income suffer about a third more colds than families at the upper end.Lower income generally forces people to live in closer quarters than those typically occupied by wealthier people, and crowding increases the opportunities for the cold virus to travel from person to person.Low income may also influence diet.The degree to which poor nutrition affects susceptibility to colds is not yet clearly proved, but an inadequate diet is suspected of lowering resistance generally.
68. What factors cause people to catch colds easily?
A. Age and pregnancy. B. Health and pregnancy.
C. Health and economics. D. Age and economics.
69. Why does the lowest income lead to the rapid spread of colds?
A. Because poor people can"t afford to go to see a doctor.
B. Because balanced diet has definitely affected poor people.
C. Because people with the lowest income have limited living space.
D. Because cold virus don"t have opportunities to travel in poor families.
70. How does the study prove that age plays a part in susceptibility to colds?
A. Using comparison. B. Using graphs.
C. Using description. D. Using argument.
71. What can you learn from the passage?
A. Families with the lowest income suffer less colds than rich families.
B. The general frequency of colds are likely to increase among the poor.
C. Women in their twenties are most likely to avoid cold infections.
D. The general frequency of colds continue to rise into the adults.

Teachers have long said that success is its own reward. But these days, some students are finding that good grades can bring them cash and luxury gifts.
In at least a dozen states this school year, students who bring home top marks can expect more than just thankfulness.
The most ambitious experiment began in September, when seven states—Arkansas, Alabama, Connecticut, Kentucky, Massachusetts, Virginia and Washington—won spots in an Mobilfunded program that, in most cases, pays students $100 for each passing grade on advanced placement(AP) collegeprep exams.
It’s an effort to get lowincome and minority students interested in the courses, says Tommie Sue Anthony, president of the Arkansas Advanced Initiative for Math and Science. “We still have students who are not sure of the value, who are not willing to take the courses.” she says, “Probably the motivation will make a difference with those students.”
Gregg Fleisher of the National Math and Science Initiative, which runs the sevenstate program, says the effort is modeled on a program adopted by Dallas in the 1995-1996 school year that saw AP coursetaking jump obviously. That program is now statewide.
While many educators would be against offering kids cash for good grades, Fleisher and others say the idea is simple. “It’s an encouragement to get them to basically make the right decision and choose a more strict class.” he says, “This teaches them that if they work at something very hard and have a lot of support, they can do something they didn’t think they could do.”
An analysis of the Texas program last month by Cornell economist C.Kirabo Jackson found that it linked to a 30% rise in the number of students with high SAT and ACT scores and an 8% rise in collegegoing students.

B.To help poor students to keep on with education.
C.To offer poor students luxury gifts on their birthdays.
D.To make an effort to raise the value of money.
53.Which of the following statements is TRUE?

B.The program was probably first adopted by Dallas.
C.The program has been going on half a dozen states this year.

Many people think that college bookstore are the most convenient source for textbooks. Titles are usually in-stock and students may purchase new textbooks or choose to buy second-hand books and save money . But the money saved by purchasing second-hand textbooks from college bookstores is small compared to the amount they could save by shopping online.

Online auctions(拍卖) are another option for students seeking a bargain. This option, however, has its pros and cons. A plus is that students can get incredibly cheap books. One problem is that while online bookstores have a system in place that ensure you receive your order within a reasonable amount of time, with an auction purchase, however, you must depend on the auction seller"s timetable.
One way that students can really save is by getting books for free. Project Gutenberg is one resource that English majors will find invaluable. Here students can legally download a huge collection of classic novels. In the past students needing help with their studies would often have to spend a lot of money buying expensive study guides. Today that is no longer the case. Cash-strapped students can now visit the website SparkNotes for free downloadable study guides as well as classics.
56. Which of the following is the best title of this passage?
A. Learning to save money on Textbooks B. Why Buy Textbooks
C. Tips for Buying Secondhand Textbooks D. Online Shopping
57. Which of the following is NOT mentioned as a source to obtain textbooks ?
A. Online used bookstores. B. College bookstores.
C. Online auctions. D. Secondhand bookstore centres.
58. The underlined expression ‘pros and cons’(paragraph 4) is closest in meaning to __________.
A. professionals and conservatives B. processes and conditions
C. joy and sadness D. good and bad points
59. According to the passage, Project Gutenberg is probably __________.
A. a project to help poor students get free learning materials
B. a government project aimed at helping English majors
C. a website for English majors to get the guides from language experts
D. a website for students to get free sources for English learning
60. From the passage, we can learn that__________.
A. online auctions are perfect for students seeking text books.
B. students should visit many websites before buying their books.
C. the cost of textbooks in college is low compared to the amount spent on tuition
D. students should consider shopping costs and delivery time above all else when making their buying decision.

Energy-saving Finns invented the first ice skate more than 5,000 years ago, as a practical method of transport to make getting across frozen lakes less of a struggle.
The earliest skates would have been blades made from bones and are one of the oldest means of transport ever discovered —they may even have been essential survival tools.
Researchers at Manchester Metropolitan University have calculated that ice skates would have saved energy by 10 percent, and suggest that they were developed for practical use and were not used for recreation, as they are today.
They think the most likely birthplace of skating is southern Finland, where there are many icy lakes.
The scientists have put their theory to the test and made replica(复制品) skates modeled after examples held at the British Museum and the Fitzwilliam Museum in Cambridge.
Volunteers on ice rinks in the Alps had their heart rates, oxygen intake and skating speeds measured while they skated with the replica skates. From this experiment, re-searchers were able to calculate energy consumption and the efficiency of their skating. They discovered that skating over the land in ancient Fin-land would have saved 10 percent of people’s energy. The result is based on the fact that Finland has the highest concentration of lakes in the world. The ancient Finnish people could benefit more than others from developing this tool for transport.
In a time and environment in which the balance between energy taken from food and energy required to live was crucial; the least cost of energy might have helped humans survive in extreme conditions.
45. The first ice skate invented by the Finns was used for _____.
A. recreation B. transportation across lakes
C. saving energy D. sports
46. The birthplace of skating might be southern Finland because _____.
A. there are many icy lakes there
B. people need more oxygen to breathe in there
C. people feel tired easily there
D. transportation there is more difficult
47. Scientists have experimented with replica skates and found that with those skates the ancient
Finnish people would have _____.
A. crossed a lot of lakes
B. saved 10 percent of energy when crossing the lakes
C. climbed the Alps easily
D. otherwise wasted a lot of food and energy
48. It can be inferred from the story that _____.
A. the Finnish people were clever enough to invent the practical skates
B. there were a lot of lakes in ancient Finland
C. the living conditions were very hard for the ancient Finnish people
D. it was very cold in ancient times in Finland
