浙江省平阳县昆阳镇第三中学高三英语 练习题1（无答案）awhy do men die earlier than women? the latest research makes it known that the reason could be that mens hearts go into rapid decline when they reach middle age.the largest study of the effects of ageing on the heart has found that womens longevity may be linked to the fact that their hearts do not lose their pumping power with age.“we have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, david goldspink of liverpool john moores university in the uk.“within the heart there are millions of cells that enable it to beat. between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said goldspink. “this is part of the ageing process.”what surprises scientists is that the female heart sees very little loss of these cells. a healthy 70-year-old womans heart could perform almost as well as a 20-year-old ones.“this difference might just explain why women live longer than men,” said goldspink. they studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “the team has yet to find why ageing takes a greater loss on the male heart,” said goldspink.the good news is that men can improve the health of their heart with regular exercise. goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.51. the underlined word “longevity” probably refers to “_”.a. health b. long life c. ageing d. effect52.

been using the installment plan since the first half of the twentieth century. today, a large number of families in great britain buy furniture, household goods and cars by installments. in the u. s. , the figure is much higher than in great britain, and people there spend over 10 percent of their income on the installment plan. the price of an article bought on installments is always higher than the price that would be paid by cash. there is a charge for interest. the buyer pays one quarter or one third of the price as a down payment when the goods are delivered to him. he then makes regular payments, weekly or monthly, until the full price is paid up. the legal ownership of the goods remains with the seller until the final payment has been made. installment buying has advantages and disadvantages. it can help couples with small incomes to furnish their homes and start housekeeping. it increases the demand for goods, and in this way helps business and employment. there is, however, the danger that when business is bad, installment buying may end suddenly, making business much worse. this may result in a great increase in unemployment. if the people on the installment plan lose their jobs, they will probably not be able to make their payments. if great numbers of people are not able to pay their installment debts there is a possibility that businessmen cannot collect their debts and will therefore lose money. if businessmen lose money or fail to make a satisfactory profit, it becomes more likely to have a depression(经济萧条). this is why, in some countries, the government controls the installment plan by fixing the amount of the down payment and installments to discourage people from buying more than they can pay for on the installment plan.56. which of the following is not true about the installment plan?a. a lot of british families use the installment plan.b. more than 10 percent american families buy things on installments.c. americans depend more

will happen to a buyer if he fails to make the full payment for an item bought on installments?a. he might lose his job. b. he will stop owning the item he has bought.c. he will have to sell what he has bought. d. he will go into debt.59. the advantage of installment buying might include all the following except that _.a. purchasing power is strengthenedb. employment might be increasedc. people develop a good habit of saving moneyd. young couples are able to furnish their homes60. in some countries, the governments control the installment plan to _.a. increase employment b ensure that

large populations have the biggest problem of dirty air. air pollution is caused by many different things. a major source of air pollution is the gas fumes from cars. statistics show that 93 percent of all auto trips are within cities. another major source of dirty air is the burning of coal and oil for energy. this energy is needed to make electricity. of course, much more electricity is used in the city than in the country. on the average, we throw away more trash and garbage than the year before. the burning of garbage contributes to air pollution. many major industries are also responsible for the dirty air in the around cities. the fumes from iron, steel, chemical, and petroleum production add particles to the air. the effects of air pollution range from mild headaches to death. the levels of pollution found in heavy traffic may cause headaches or loss of clear vision. wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. in some of

survey on money and relationships, 36% of people are keeping a bank account from their partner. while this financial unfaithfulness may appear as distrust in a relationship, in truth it may just be a form of financial protection. with almost half of all marriages ending in divorce(离婚), men and women are realizing they need to be financially savvy, regardless of whether they are in a relationship. the financial hardship on individuals after a divorce can be extremely difficult, even more so when children are involved. the lack of permanency in relationships, job and family life may be the cause of a growing trend to keep a secret bank account hidden from a partner, in other words, an “escape fund”. margarets story is far from unique. she is a representative of a growing number of women in long-term relationships who are becoming protective of their own earnings. every month on pay day, she banks hundreds of dollars into a savings account she keeps from her husband. she has been doing this throughout their six-year marriage and has built a nest egg worth an incredible $100,000. margaret says if her husband found about her secret savings hed be hurt and would take this as a sign that she wasnt sure of the marriage. “hed think it was my escape fund so that financially i could afford to get out of the relationship if it went wrong. i know you should approach marriage as being forever and i hope ours is, but you can never be sure.” like many of her fellow secret savers, margaret was hurt in a previous failed marriage and has since been very guarded about her own money. coming clean to your partner about being a secret saver may not be all that bad. taken colleen for example, who had been saving secretly for
