Researchers in the psychology department at the University of California at Los Angeles (UCLA) have discovered a major difference in the way men and women respond to stress. This difference may explain why men are more likely to suffer from stress-related disorders.

Until now, psychological research has maintained that both men and women have the same "fight-or-flight" reaction to stress. In other words, individuals either react with aggressive behavior, such as verbal or physical conflict ("fight"), or they react by withdrawing from the stressful situation ("flight"). However, the UCLA research team found that men and women have quite different biological and behavioral responses to stress. While men often react to stress in the fight-or-flight response, women often have another kind of reaction which could be called "tend and befriend." That is, they often react to stressful conditions by protecting and nurturing their young ("tend"), and by looking for social contact and support from others - especially other females ('befriend").

Scientists have long known that in the fight-or- flight reaction to stress, an important role is played by certain hormones(激素) released by the body. The UCLA research team suggests that the female tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied in the context of childbirth, but now it is being studied for its role in the response of both men and women to stress. The principal investigator, Dr. Shelley E. Taylor, explained that "animals and people with high levels of oxytocin are calmer, more relaxed, more social, and less anxious." While men also secrete(分泌）oxytocin, its effects are reduced by male hormones.

In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions if they are lost.

The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children and their needs.

The differences in responding to stress may explain the fact that women have lower frequency of stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend regulatory(調節(jié)的) system may protect women against stress, and this may explain why women on average live longer than men.

1.The UCLA study shows that in response to stress, men are more likely than women to _____ .

A. turn to friends for helpB. solve a conflict calmly

C. find an escape from realityD. seek comfort from children

A. Men have the same level of oxytocin as women do.

B. Oxytocin used to be studied in both men and women.

D. Oxytocin has more of an effect on women than on men.

3.What can be learned from the passage?

A. Male hormones help build up the body's resistance to stress.

B. In a family a mother cares more about children than a father does.

C. Biological differences lead to different behavioral responses to stress.

D. The UCLA study was designed to confirm previous research findings.

4.Which of the following might be the best title of the passage?

A. How men and women get over stress

B. How men and women suffer from stress

When we talk about superstitious（迷信的）beliefs , the beliefs associated with Friday the 13th , no doubt , deserve a special mention . In fact , such is the fear associated with this date that people just can’t seem to stick to their daily routine on this day . The data from Stress Management Center and Phobia Institute suggests that somewhere around 17 to 21 million Americans are affected by the fear associated with this day , i.e. the combination of Friday and 13 . Even worse , the financial losses caused on this day amounts to as much as US$800 million every year .

As we flipped through the pages of history , we realized that Friday the 13th bears the brunt of bad luck associated with number 13 , the unluckiest number , and Friday , the unluckiest day of the week . Number 13 has always been considered unlucky , mainly as a result of it being associated with various occurrences in mythology . While some associate it with the instance of Norse mythology , in which the god of joy and gladness – Balter , was killed in a dishonest manner by Loki – the god of discord and mischief , who was the 13th guest , others associate it with the Last Supper , in which the 13th guest was Judas , who betrayed Jesus to his enemies for 30 pieces of silver .

Similarly , Friday has also been a sign of bad luck to many people , with incidents like Jesus being crucified（在十字架上釘死）on this unfaithful day , contributing to this belief . It is also widely believed that Cain killed Able on this very day of the week . The fear of Friday the 13th is known as friggatriskaidekaphobia and paraskevidekatriaphobia , the former combining the words frigga , meaning Friday , and triskaidekaphobia , meaning the phobia of number 13 . Over the period , the belief that Friday the 13th is an unlucky day has just become one of the most widely accepted superstitions , which consequently causes much blind panic and unreasonable fear in the world .

1.What does Friday the 13th refer to according to passage ?

A. The 13th Friday of a year .
