　　Middle Age: A Low Point for Most

　　People around the globe hit the height of their misery and depression in middle (51)　　, a new international study suggests. The finding by British and American researchers was based on an analysis of well-being among approximately 2 million people in 80 nations. With few exceptions, the observation appears to apply across the board, regardless 　　(52)　　 gender (性别), culture, geography, wealth, job history, education, and marriage or parental status.

　　"The scientific fact seems to be that happiness and positive mental health follow a giant 'U'　　(53)　　through life," said study author Andrew J. Oswald, a professor of economics at Warwick University in Warwickshire, England. "For the average person, it's high when you're 20, and then it slowly　　(54)　　and bottoms out in your 40s. But the good news is that your　　(55)　　health picks up again, and eventually gets back to the high levels of your youth."

　　The finding was　　(56)　　on the pooling of several different sources of happiness data, including: two multi-decade happiness/satisfaction surveys (first launched in the 1970s), involving about 500,000 American and Western European men

　　and women; four rounds of the 80-nation "World Values Survey"　　(57)　　between 1981 and 2004 in North America, Eastern and Western Europe, Asia, Africa, Australia, and Central and South America; and a 2004-2007 survey　　(58)　　nearly 1 million Britons.

　　The bottom-line: For most people throughout the world, the highest probability for　　(59)　　striking is around 44 years of age.

　　In the United States, however, some as-yet unexplained　　(60)　　differences were observed, with happiness among men dipping the most in their early 50s, whereas women hit their nadir (最低点) around the age of 40.

　　The researchers cautioned that cheerful people tend to live longer than unhappy

　　(61)　　- a fact that might have skewed (使偏斜) the overall finding. But they also suggested that evidence of a happiness　　(62)　　might simply reflect a midlife choice to give up long-held but no longer tenable (守得住的) aspirations (志向), followed by a senior's sense of gratitude for having successfully endured 　　(63)　　others did not.

　　"That said, some might find it helpful simply to understand the general　　(64)　of mental health as they go through their own life," said Oswald. "It might

　　be useful for people to realize that if they are　　(65)　　in their 40s this is normal. It is not exceptional. And just knowing this might help."

　　A Biological Clock

　　Every living thing has what scientists call a biological clock that controls behavior. The biological clock tells __1__ when to form flowers and when the flowers should open. It tells __2__ when to leave the protective cocoon and fly away, and it tells animals and human beings when to eat, sleep and wake.

　　Events outside the plant and animal __3__ the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur __4__ the number of hours of daylight. In the short __5__ of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer.

　　Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to begin their long migration __6__ twice each year. Birds __7__ from flying become restless when it is time for the trip, __8__ they become calm again when the time of the flight has ended.

　　Scientists say they are beginning to learn which __9__ of the brain contain biological clocks. An American researcher, Martin Moorhead, said a small group of cells near the front of the brain __10__ to control the timing of some of our actions. These __11__ tell a person when to __12__, when to sleep and when to seek food. Scientists say there probably are other biological clock cells that control other body activities.

　　Dr. Moorhead is studying __13__ our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours. __14__ can take many days for a human body to accept the major change in work hours. Dr. Moorhead said industrial officials should have a better understanding of biological clocks and how they affect workers. He said __15__ understanding could cut sickness and accidents at work and would help increase a factory's production.
