An important factor that plays a part in susceptibility （易受影响） to colds is age．A study done by the University of Michigan School of Public Health indicated the fact that seems to hold true for the general population．Babies are the group suffering most from colds, averaging more than six colds in their first years．Boys have more colds than girls up to age three．After the age of three, girls are more susceptible than boys, and teenage girls average three colds a year to boy's two．

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．

1.What factors cause people to catch colds easily?

A. Age and pregnancy．                  B. Health and pregnancy．

C. Health and economics．               D. Age and economics．

2.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．

3.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．

4.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．

Let's do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. On Monday morning, you were feeling so bright-eyed, and you only had one cup of coffee, instead of your usual two. But don't be cheated by your energy: You're still carrying around a heavy load of sleepiness, or what experts call " sleep debt "win this case something like six hours, almost a full night's sleep.

  Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get. It's a deficit (赤字)that grows every time we skim some extra minutes off our nightly sleep. "People accumulate sleep debt gradually without being noticed," says psychiatrist William C. Dement, founder of the Stanford University Sleep Research Centre. Studies show that such short-term lack of sleep

leads to a foggy brain, worsened vision, and trouble remembering. Long-term effects include obesity, insulin(胰岛素) resistance, and heart disease. A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night —more than two full weeks of sleep each year.

  The good news is that, like all debt, with some work, sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up. For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired, and allow your body to wake you in the morning (no alarm clock allowed). You may find yourself catatonic (有紧张感的)in the beginning of the recovery cycle: Expect to have ten hours' shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease.

   So earn back that lost sleep —and follow the orders of your inner sleep needs, and you'll feel better. "When you put away sleep debt, you become superman." Says Stanford's Dement, talking about the improved mental and physical capabilities that come with being well rested.

1.The example of sleep math is used to show       .                                                                                           

A. in what case you build up a sleep debt

B. why you need six hours' sleep every night.

C. why you are full of energy even when lacking sleep.

D. you should drink coffee to keep energetic

2.The author begins Paragraph 2 with       .

A. an example     B. a definition     C. an order     D. a story

3.By saying the underlined sentence in the last paragraph, Dement means       .

A. a superman always needs a lot of sleep

B. you can become superhuman after you repay your debt

C. you will be in a good state with enough sleep

D. you will become superhuman if you don't make up for sleep debt

4.What might be the most suitable title for the passage?

 A. How can you keep energetic?     B. Can you have a good sleep?

 C. What is sleep debt?             D. Can you catch up on sleep debt?
