自选模块英语部分试题

阅读下面短文，并根据短文后的要求答题。

The day before a long flight you are hurrying through last-minute chores and errands，packing and  reading  guide books.Then，on the plane ，you have several drinks with dinner and stay up late watching  the movie.After a brief nap ，it’s time for breakfast and a morning arrival in，let’s say，Paris or Rome．Adrenaline(肾上腺素)flowing，you spend the entire day sightseeing and taking pictures .By evening，exhaustion has set in，and the next morning，you can hardly wake up before noon ．   _ 

Most people who travel by air across multiple time zones fall victim to this trouble of modem air travel .They may suffer from any of a number of unpleasant symptoms ，including sleeplessness，fatigue(疲劳)，sickness，and sleepiness.Acording to Dr.Harriet Minsky，professor of psychology at Montreal University，the symptoms of jet lag(飞行时差反应)vary from person to person ，and also vary according to how far a traveler has flown Recovery from jet lag also varies  _   Dr.Minsky points out that there are three  primary causes of jet lag， and of these， two are avoidable．First， people often wear themselves out getting ready for a trip， so they are already exhausted when they get on the plane．Second， long-distance travelers often have a couple of drinks to pass the time．The alcohol can cause a stomach upset and disturb their sleep.

The third and unavoidable cause of jet lag is the fact that long distance air travel upsets your internal biological clock．Dr．Alvin Lacy， chief of general medicine at Northern Medical College， explains that our inner clock controls our cycle of sleeping and waking.  _    Without them， the brain tends to set its biological clock to a longer day．This means that， for most travelers， the effects of jet lag are less severe on trips toward the west， because the travel is following the sun．In traveling toward the east， the body must adjust by shortening its day， going against the body's natural tendency．This explains why trips from west to east often result in greater suffering from jet lag.   _    For example， Mnight owls，M people who are usually most alert and lively late at night， are less

likely to feel the effects of jet lag．In terms of personality types， extroverts (people who are sociable and like to be in groups) tend to suffer less than introverts.

Many people believe that there must be some quick and easy cures for jetag-from vitamins   (维生素)to special diets，  but  research has  shown  that none of these are very effective．However， Dr．Minsky tells travelers that if they follow certain common sense strategies， they will overcome jet lag more quickly.
