    Come prepared: When you arrive at a race, your bike should be in race-ready condition.
    Chain Management: Chain damage is still the number one problem with mountain bikes. Keeping your chain clean and well-oiled will help, as will frequent chain replacement. Periodic inspection of your chain for wear, stretch and damage may save you a long walk home.
    Packing Tape: This can be used for rims trips, boots for fractured tires and a dozen more makeshift repairs. If you've flown to the race, it also saves you from having to borrow tape to close up your bike box for the flight home. Other musts: safety pins and plastic zip ties.
    Pre-race: Visual inspections before any serious off-road ride, carefully examine the area where the tire hooks onto the rim and remove any foreign objects which could cause premature（比预期早的）tire wear.
    Tire Pressure: Check tire pressure before race start. The recommended pressure is noted on the tire sidewall, usually 40 lbs., many racers run 50 lbs., or more for less rolling resistance.
    Be Self-Contained: Make sure you are self-contained. Bring your own drinking water, food and first aid kit. Also have tools, spare parts, tubes, quick fills and a chain tool. Never suppose you can just borrow these items from a friend.
    Post-race Visual Inspections: Inspect your bike after completing each event, especially before competing in a downhill event. Re-inspect before packing your bike for the trip home.
    Have Fun!

    My husband had just bought a new washing machine for me. I decided to use it the  21  day, and I washed a lot of things. Everything worked  22  , but I couldn't find 23  of my husband's socks though I had looked 24  for it.

    When I turned  28   to write on the blackboard, the class burst out 29  . They laughed and laughed. They laughed so much, in fact, that I was  30   the headmaster would be in to see all this.
    I asked the class to  31  , but the 32 I talked, the more they laughed. So I thought I had better pay  33   attention to them and continue to write on the blackboard. When I did this, they laughed even more.

    "Good  Heavens ! "I said. "Will   37  please tell me what is so  38 ?"

    So that's   40   I found my husband's missing sock.

    Here are some of the most common causes of fatigue, and what you can do about them.
    Inadequate Sleep. If you don’t get enough sleep you’ll be tired but it’s rare that busy people get enough sleep. When there aren’t enough hours in the day to do everything, something has to give, and that’s usually sleep. Don’t fool yourself that you can get by on five or six hours of sleep a night. Most people need at least eight hours and some even more.
    Hormone Imbalances. Thyroid disease is extremely common today, especially among young women and the elderly. As common as thyroid disease is, its symptoms are so similar to so many other ailments that it often goes unnoticed by both doctors and patients. If you’re suffering from fatigue, get your thyroid hormone levels checked.
    Food Allergies. You may be allergic to common foods like dairy, eggs, nuts, wheat, corn, chocolate, or coffee. If you suffer from coughing or wheezing, digestive problems, headaches, muscle aches or joint pain, itching and skin problems, in addition to fatigue, try cutting out each of these foods for a week to see if you feel better without it. Also, don’t eat excessive amounts of any particular food during any one day.
    Environmental Toxins. Fatigue may result from our polluted environment. If, in addition to fatigue, you suffer from headaches, allergies or respiratory problems, you may be absorbing airborne toxins. Check the ventilation system in your home and office. Buy houseplants, air filters, and water filters for your home. If you’re working in a “sick” building you may have to look for another job.
    Couch Potato Syndrome. Fifty percent of depression and fatigue can be caused by inactivity. For an energy boost, do anything that gets you moving for 20 to 30 minutes a day.
    Anemia. Anemia can be a hidden disease in women. If you’re tired for no known reason, have your total iron count taken. Sometimes, even though your blood count may show a normal level of red blood cells, you may still be deficient in iron. If your iron count is low, you may need supplements.
    Cigarette Smoking. Cigarettes are an enormous energy drain. They rob the body’s cells of oxygen and produce carbon monoxide poisoning.
    Too Much Coffee. If you drink a lot of coffee in the effort to beat fatigue, in the long run you’ll be even more tired. Coffee gives you a temporary lift at the cost of long-term energy.
    Poor Nutrition. The typical American diet, high in refined foods and animal fat, supplies inadequate nutrients and drains energy. Switch to a diet low in animal protein and saturated fat and high in fruits, vegetables, grains and beans. Cut out highly processed foods. Take vitamins.
    62. What does the underlined word “fatigue” mean?
    A. tiredness        B. weakness         C. sickness          D. laziness
    63. Couch potato syndrome has something to do with ______.
    A. potato          B. couch            C. energy           D. inactivity
    64. According to the passage, you can infer that ______.
    A. you can always do with five or six hours of sleep a night.
    B. fifty percent of depression and fatigue can be caused by inactivity.
    C. it’s easier for women to catch thyroid disease or anemia.
    D. the more coffee you drink, the less tired you are.
    65. Which of the following is NOT one of the causes of fatigue according to the passage?
    A. Polluted environment.          B. Cigarette smoking.           C. Low iron count.
    D. A diet low in animal protein and saturated fat and high in fruits, vegetables, grains and beans.

    Four Insurance Policies You Can' t Do Without
    A single gap in insurance coverage could wipe out the money that yon' ve earned for many years through your hard work.That' s why it' s important to give yourself a yearly insurance checkup, whether you buy your policies through an agent or from one of the growing number of insurance companies.
    Health.Before selecting a policy from your employer or deciding among Medicare options, review your current health,predictable medical needs, and family status.This review should help you avoid a plan that fails to cover a necessary treatment or paying for services that you know you'll never use.
    Disability. Your chances of becoming disabled before you retire are far greater than your chances of dying. So every working person needs some kind of disability coverage. If you are working for an employer who offers less than that, you can buy an individual policy to promote your coverage.
    Homeowners or renters. Make sure you have replacement-cost coverage that would pay the current costs of rebuilding your home and replacing your personal possessions. A policy that would only pay for the decrease in value of these items isn' t good enough, because you could end up recovering just a small part of their costs. Don' t forget flood and/or earthquake insurance if you live in a locate that has a possible tendency to these types of disasters.
    Life. Empty nesters and retirees may. no longer need life insurance at all. But if you have dependents who would suffer financially if you died, it' s still a must.
    65. To have your insurance checkup every year is mainly because _______.
    A. the gap in insurance coverage could cost you a large sum
    B. the gap in insurance coverage could bring you benefits
    C. some insurance agencies cover few of your policies
    D. too many insurance companies prefer to sell coverage
    66. _______ can be ignored while deciding among Medicare choices.
    A. Your necessary treatment.                   B. Your personal health at present.
    C. Your social status.                           D. Your predictable medical needs.
    67. Which of the following is NOT true according to the passage?
    A. Workers needn' t buy personal disability coverage if their bosses offer that
    B. Insurance companies can secure the full value of private possessions
    C. Earthquake insurance can cover replacement-cost caused by the disaster
    D. Divorced or retired people may need life insurance for their dependents
    68. We can infer that demand for insurance_______.
    A. varies due to individual needs of coverage
    B. stays the same whether you are working or not
    C. increases when we move to a new place
    D. decreases if we have a large family to support

    How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs?
    These are two important questions that many people are asking today. Some people think that men might be able to solve both problems at the same time. They suggest using garbage as an energy source.
    For a long time people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. But garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source.
    Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the city's garbage each year. The amount of energy produced is about the same as the world produced by burning almost a half million barrels of oil!
    But there are problems in using garbage as a fuel. Garbage that burns easily, such as food scraps and paper, must be separated from metals, glass, and other materials that do not burn easily. This separation process is normally costly. Another problem is that burning garbage can pollute the air.
    Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount of garbage piling up on the earth.
    53. What two problems can be solved by burning garbage?
    A. The shortage of energy; Air pollution.
    B. The shortage of energy; the shortage of empty land for holding garbage.
    C. Air pollution; the shortage of empty land for holding garbage.
    D. Air pollution; the shortage of fossil fuel.
    54.Which of the following is NOT a result of burning garbage?
    A. The heat produced is used to boil water.
    B. The steam produced is used to make electricity.
    C. The garbage burned is turned into fossil fuels.
    D. The steam produced is used to heat buildings.
    55.According to the passage. Which of the following four groups of garbage is ready for burning?
    A. food scraps and metals                    B. paper and glass
    C. metals and glass                             D. food scraps and paper
    56.What is the general tone of the passage?
    A. optimistic                       B. indifferent                     C. advocating               D. anxious

    Poverty exists because our society is an unequal one, and there are plenty of political pressures to keep it that way. Any attempt to redistribute wealth and income in the United States will be opposed by powerful middle and upper class interests. People can be relatively rich only if others are relatively poor, and since power is concentrated in the hands of the rich, public policies will continue to reflect their interests rather than those of the poor.
    　　As Herbert Gans has pointed out, poverty is actually functional form from the point of view of the non-poor. Poverty ensures that ‘dirty’ work gets done. If there were no poor people to clean floors and empty dustbins, these jobs would have to be rewarded with high incomes before anyone would touch them. Poverty creates jobs for many of the non-poor, such as police officers, welfare workers, and government officials. Poverty makes life easier for the rich by providing them with cooks, gardeners and other workers to perform basic work while their employers enjoy more pleasurable activities. Poverty provides a market for low-level goods and services, such as day-old bread, rundown automobiles. Poverty legitimizes (make legal) middle-class values. To the middle class, the fate of the poor---who are supposed to lack honesty, and a taste of hard work---only confirms the desirability of qualities the poor are thought to lack. Poverty also provides a group that can be made to absorb the costs of change. For example, the poor bear the pressure of unemployment and it’s their homes, not those of the wealthy, that are destroyed when a route has to be found for a new highway. It cannot be said that the wealthy keep the poor in poverty. It is just that poverty is an outcome of the American economic system, which the poor are politically powerless to influence or change.
    小题1: The best title is ________________________.
    A．Functions of PovertyB．Political Power in Poverty
    C．The Fate of the PoorD．An Unequal Society
    小题2: Poverty exists in American society because ____________.
    A．the wealthy work hard and are glad to keep it　　
    B．the majority of the non-poor are totally indifferent (not paying much attention) to it　
    C．the rich are politically powerful while the poor are politically powerless　
    D．the poor like the jobs that they’re supplied by the wealthy.
    小题3:The poor take on ‘dirty work’ ___________________.   
    A．under political pressureB．for the high pay offered
    C．as they are reasonably paidD．though ill-paid
    小题4: The author thinks that _____________________.
    A．the poor lack such desirable qualities as honesty　　
    B．the poor are not supposed to work hard　　
    C．the poor are willing to bear the costs of changeD．none of the above

    Oceanography has been defined as “The application of all sciences to the study of the sea”. Before the nineteenth century, scientists with an interest in the sea were few .
    　　 For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question 'What is at the bottom of the oceans?' had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile (起伏形状 ) of the route to estimate the length of cable that had to be manufactured. 
    　　 It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings (测深 ) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. 
    　　 The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.
    　　Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.
    　68. The passage implies that the telegraph cable was built mainly _________.
    　A) for oceanographic studies
    　B) for military purposes
    C) for business considerations
    　D) for investigating the depths of the oceans
    69. The aim of voyages Maury encouraged in the 1840s was __________.
    　A) to make some sound experiments in the oceans
    　B) to collect samples of sea plants and animals
    　C) to estimate the length of cable that was to be made
    　D) to measure the depths of two oceans
    70. 'Defied' in the 4th paragraph probably means ________
    　A)   doubted        B)  gave proof to
    　C)   challenged     D)  agreed to
    71. This passage is mainly about _________
    　A) the beginnings of oceanography
    　B) the laying of the first undersea cable
    C) the investigation of ocean depths
    　D) the early intercontinental communications
