"Humans should not try to avoid stress any more than they would shun food, love or exercise." said Dr. Hans Selye, the first physician to document the effects of stress on the body. While here’s no question that continuous stress is harmful, several studies suggest that challenging situations in which you’re able to rise to the occasion can be good for you. In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they couldn’t get the job done. Stress that you can manage may also boost immune(免疫的)function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects believed they had control over the outcome. In the second, they weren’t in control: They had to sit through a gory(血淋淋的)video on surgical procedures. Those who did go on the memory test had an increase in levels of immunoglobulin(免疫球蛋白)A, an antibody that’s the body’s first line of defense against germs. The video-watchers experienced a downturn in the antibody. Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. "They can help nerve cells handle information and put it into storage," says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain. "Sustained stress is not good for you," says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity (长寿),"It’s the occasional burst of stress or brief exposure to stress that could be protective. "(325w) In the experiment described in Paragraph 3, the video-watchers experienced a downturn in the antibody because ______.

There is no question that raising teenagers is a challenge no matter how many parents are living in the home. Particularly challenging are the ages between 12 and 16,which are marked by mood swings, defiant attitudes, and attempts to push the limits set by their parents. During this time, teens are trying their hardest to gain adult independence, which is a normal part of the natural growing process. So, we accept this as a time to help them learn lessons and find their way to adulthood, despite the fact that it sometimes makes us feel like we are raising aliens from another planet! Two parents in the household can be a definite plus during these years, especially if both are healthy and loving. In single parent homes, a healthy and loving atmosphere is also a key ingredient to raising responsible teens. Also, teens are often masters at pitting (使人相斗)their parents against one another, so when they have divorced parents living in different households, it can be extra difficult to co-parent with effectiveness. What can single parents do to make the teens in their homes more pleasant The suggestion is to create realistic and enforceable boundaries. Let your kids know that you will negotiate boundaries every six months, for instance. Let them come up with ideas so that they will be more apt to comply. The topics to discuss may be such as how they spend their time after school, how they spend time with their friends and how should be their dress code and their hairstyles, and so on. However, when it comes to alcohol, drugs, smoking and other obvious health risks, there should be no negotiation at all. I never give them permission to drink—and that was final. Let them know they are responsible for their own behavior and should take themselves out of situations that could lead to trouble. A week before your six-month meeting with your teen, call the other parent and talk about how things have been going in each household. Most of the time, there is a wide range of healthy variations in parenting styles. Explain to your teens that when they enter the workforce, they will work with different supervisors, so operating under different household guidelines should be respected and will be good training for their future. In the second paragraph, the author implies that ______.
He has been at the helm (舵)of the Securities and Exchange Commission for only three months, but William Donaldson has given individual investors reason to believe that he will prove to be an effective champion of their interests as a vigilant regulator of the nation’s financial markets. The challenges ahead remain daunting, but Mr. Donaldson is steadily restoring the agency’s credibility in the wake of its disastrous stewardship by Harvey Pitt. The SEC. chairman passed his first big test by persuading William McDonough, the respected president of the New York Federal Reserve, to run the new accounting oversight board created by Congress last summer. He has also opened an important inquiry into trading practices at the New York Stock Exchange. The commission has issued rules to tighten corporate boards’ oversight over financial audits. Mr. Donaldson should now see that more is done to shore up shareholder democracy. A reassuring sign that there is a new sheriff(治安官)on Wall Street came in the aftermath of the recently announced landmark settlement with 10 brokerage(经纪人业务)firms over their tainted stock research. The SEC. chairman sternly rebuked Philip Purcell, the chief executive of Morgan Stanley, for trying to minimize the extent of his firm’s involvement in the scandals. Mr. Donaldson, a former Wall Street banker himself, wrote a letter to Mr. Purcell describing concern over his "troubling lack of contrition" , and reminding him that Morgan could face further legal problems if it denied the settled charges. Besides being unusual, Mr. Donaldson’s move was a powerful use of his office’s bully pulpit (讲坛). With all the talk about whether the SEC. has enough material resources to pursue corporate malfeasance—the agency’s budget is being increased significantly—it was easy in the Harvey Pitt era to forget that a strong SEC chairman can wield a great deal of moral authority. This is especially true given financial institutions absolute need to retain public trust. Mr. Donaldson should be ready to use his bully pulpit often. Wall Street is awash in a "troubling lack of contrition" for its past misdeeds. Which of the following statements agrees with the facts appear in the passage
