A new study by Penn State College of Medicine research team found that honey is a better and safer treatment for children than cough medicines.

   Ian Paul, the study’s lead researcher, was motivated to test honey because treating coughs in children has recently become a sticky subject. Coughing is the body’s way of cleaning irritated (受刺激的) airways to help you breathe. But too much coughing can irritate your lungs and throat even more. It can also make it tough to get the sleep your body needs to heal. Hoping to ease the suffering of their children, parents often give them cough medicines.

But there have never been any good studies showing that they work. Cough and cold medicines may also cause serious side effects. Hundreds of kids die in the hospital each year after receiving too much cough medicine by mistake. Last October, the US Food and Drug Administration suggested that parents should not give cough medicines to children under 6.

In order to search for a different solution, Paul designed a study that involved 105 kids who were sick with coughs and other cold conditions. At bedtime, the kids took buckwheat(荞麦) honey, honey-flavored (蜜蜂味的) DM (one of the most common ingredients成分in cough medicine), or no treatment. Parents and kids in the no-treatment group knew they weren’t getting anything, but the other two groups weren’t told which treatment they were getting.

The surveys showed that kids who swallowed about 2 teaspoons of buckwheat

honey before bedtime coughed less and slept better than kids in other groups.

“When parents want something for their kids to take,” Paul says, “honey seems

 like the best option.”

But what gives honey its healing power? Substances called antioxidants(抗氧化剂) may be part of the answer. All honey contains antioxidants that protect our cells from damage. Studies show that antioxidant levels in the body rise after someone swallows honey.

Which of the following can be the best title for this passage?

A. Sweet solution to kids’ coughing

B. No cough medicines to children

   C. Best treatment for your cold

   D. Cough medicines don’t work

We can learn from Paragraph 2 that coughing ______.

   A. can cure lung and throat diseases

   B. is more harmful to children

C. sometimes does good to people 

   D. helps improve children’s die

During Paul’s experiment, the kids who received treatment __________.

   A. seemed much worse than before

B. had no idea what they swallowed

C. knew they weren’t getting anything

   D. coughed less and slept better

According to the passage, Paul’s experiment proved that ____.

A. honey may have real healing power

B. cough medicines may cause side effect

    C. cough medicines don’t really work

D. buckwheat honey contain more antioxidants

More than half of Americans do not take all their vacation days，even though they think they need one more holiday.And nearly a third of workers who take a break check their e-mails from the boss every other day and some even keep in touch hourly.

“We’re workaholics(工作狂)’，”said Samuel Nahmias.“From a general perspective，this has a lot to do with the economic situation in the US.More and more people are unemployed.”

With jobless numbers reaching 9.6 percent，people who have jobs seem to be unwilling to take time off.“It_is_not_a_great_picture and that affects vacations.People are not going on vacation as much and those who are going on vacation are being more selective about where they are going.”Nahmias explained.

Unlike European countries where four or more weeks of holiday each year is normal,27 percent of people questioned in the poll said they had 6 to 10 days of annual leave and 20 percent had less than 3 days.With more people on unemployment lists in America，those still with jobs are facing more responsibility at work，which is reflected in their lack of time off.

The majority of workers who did not take time off mentioned too many responsibilities or stress at work，while some people said they simply did not have time to plan a holiday.“People are more conscious of what they are doing and when they are going on vacation because they don’t want to look bad in this situation，”Nahmias explained.

Technology is also playing a part with smartphones enabling workers to keep in contact in ways that were not possible before.It has to do with technology and the level of concern about what is going on in the office.

According to the report by Baekeland and Hartmann, two American authoritative psychotogical research centres, the "short sleepers" had been more or less average in their sleep needs until the men were in their teens．But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions, in their daily routines.
In general, these "short sleeps" appeared ambitious, active, energetic, cheerful,, conformist （循规蹈矩的） in their opinions, and very sure about their career choices．They often held several jobs at once, or workers full - or part - time while going to school．And many of them had a strong urge to appear "normal" or "acceptable" to their friends and associates．When asked to recall their dreams, the "short sleepers" did poorly．More than this, they seemed to prefer not remembering．In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy m the hope that the trouble would go away．The sleep patterns of the “short sleepers" were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic （疯人）.
The "long sleepers" were quite different indeed．Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood．They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived （剥夺） of their desired 9 hours of nightly bed rest．They tended to recall their dreams much better than the "short sleepers．" did．Many of the "long sleepers" were shy, anxious, introverted （内向）, inhibited （压抑） , passive, mildly depressed, and unsure of themselves （particularly in social situations）．Several openly states that sleep was an escape from their daily problems．
50．According to the text, which is probably the writer' s real attitude towards these two living habits ____．

D．neither of them is healthy habits
51．When sometimes they cannot enjoy adequate sleep, the long sleepers might ____．
A．feel extremely depressed        B．become energetic
C．appeared disturbed         D．feel disappointed
52．The writer implies （暗示） that short sleepers _____ in the text．
A．are ideally vigorous even under the pressures of life
B．often neglect the consequences of inadequate（不足的）sleep
C．do not know how to relax properly
D．are more unlikely to run into mental problems

There is probably no field of human activity in which our values and lifestyles are shown more clearly and strongly than they are in the clothes that we choose to wear. The dress of an individual is a kind of "sign language" that communicates a set of information and is usually the basis on which immediate impressions are formed. Traditionally, a concern for clothes was considered to be an affair of females, while men took pride in the fact they were completely lacking in clothes consciousness(意识).
This type of American culture is by degrees changing as man dress takes on greater variety and color. Even as early as 1995, a researcher in Michigan said that men attached rather high importance to the value of clothing in daily life. White－collar workers in particular viewed dress as a symbol of ability, which could be used to impress or influence others, especially in the work situation. The white－collar worker was described as extremely concerned about the impression his clothes made on his superiors(上司). Although blue－collar workers were less aware that they might be judged on the basis of their clothing, they recognized that any difference from the accepted pattern of dress would be made fun of by fellow workers.
Since that time, of course, the patterns have changed; the typical office worker may now be wearing the blue shirt, and the laborer a white shirt, but the importance of dress has not become less.      Other researchers in recent years have helped to prove its importance in the lives of individuals at various levels and in different social and economic status groups(阶层).
