题目内容

About five states in Nigeria will experience a total eclipse (日蚀) of the sun on March 29, 2006, according to a forecast by the Ministry of Science and Technology this week.

An eclipse occurs in one of two ways: when the moon passes between the earth and the sun so that all or part of the sun cannot be seen for a time, or when the earth passes between the moon and the sun so that you cannot see all or part of the moon for a time. The first case is a solar eclipse or eclipse of the sun, which occurs as the earth enters the shadow of the moon. The second describes a lunar eclipse or eclipse of the moon, which happens when the moon enters the shadow of the earth.

More than 60 percent of Nigerians are uneducated, and eclipses in some parts of the country in the past have caused commotions in which people have been killed and property destroyed. Some Nigerians believe an eclipse is punishment from the gods for evil doing.

The March 29th eclipse would be the fifth in Nigeria’s history, and it is expected to last for 30 minutes -- 9:15AM to 9:45AM, according to the official prediction. Nigeria witnessed eclipses in 1898, 1947, 1959, and 2001.

The shadows in an eclipse have a central dark part called umbra, and a less dark external section called penumbra. In the umbra, all the sun’s light is cut off, and this is called total eclipse; while in the penumbra, only a part of the light from the sun is cut off from the moon, and it is called partial eclipse.

Five Nigerian states -- Oyo, Kwara, Niger, Zamfara, and Katsina -- are expected to have total eclipse, while other parts of the country will experience partial eclipse.

Most Americans believe that someone isn’t grown-up until the age of 26 and they should complete their education, have a full-time job, have a family to support and be financially independent. They also believe that becoming a real grown-up is a process which begins at about the age of 20 and takes about five years, according to the report from the University of Chicago’s National Opinion Research Center.
The findings are based on a representative sample of 1,398 people over the age of 18 who were surveyed in person. The survey found that people expect the transitions to grown-up status to be completed at the following ages: age 20.9 self-supporting; age 21.1 no longer living with parents; age 21.2 having a full-time job; age 22.3 education completed; age 24.5 being able to support a family financially; age 25.7 getting married; and age 26.2 having a child.
“There is a large degree of agreement across social groups on the relative importance of the seven transitions,” said Tom Smith, director of the survey. The only obvious pattern of differences is on views about supporting a family, having children and getting married. Older adults consider these more important than younger adults do. This probably shows in large part a change in values across generations away from traditional family values. The most valued step toward reaching adulthood, the survey found, is completing education, followed by full-time employment, supporting a family, financial independence, living independently, and marriage.

It’s summertime-time once again for mosquitoes to make their appearance. And once they appear, mosquitoes are a total pain. They land on you, bite you, suck out some blood and leave behind an itchy welt（发痒的红肿）.
  1  Female mosquitoes must find blood in order to reproduce, so mosquitoes come equipped with finely tuned sensors to help them locate the blood they need.
Mosquitoes’ weapons
Mosquitoes have perfected three different types of sensors. First, mosquitoes can sense several different chemicals. Mosquitoes can smell carbon dioxide and lactic acid（乳酸）up to 100 feet away.   2
Second, mosquitoes have very good eyesight. If you are wearing clothing that contrasts with the background, and if you move while wearing that clothing, mosquitoes can see you. It’s a good bet that anything moving is alive, and therefore full of blood.
Finally, mosquitoes come equipped with temperature sensors, so they can find warm-blood mammals and birds very easily.
  3  The female mosquito sticks her proboscis（喙）into you. She sucks about five microliters of your blood into her abdomen.
After she has bitten you, some saliva（唾液）remains in the wound.   4  The area swells and you tich. Eventually, the selling goes away, but the itch remains until your immune cells break down the saliva proteins.
Our defense methods
Because mosquitoes are both a nuisance（讨厌的东西） and a danger, people prefer to stay away from mosquitoes. One way to do that is to use a chemical called DEET, which seems to black a mosquito’s chemical sensors.   5  In some cities there are even trucks that drive around town to spray for mosquitoes. Finally there are to traps. The most popular traps turn propane（丙烷） into carbon dioxide and warmth to attract mosquitoes. Over time, by catching large numbers of mosquitoes, these traps can cause the collapse of the mosquito population in the area.

A．Another way to control mosquitoes is with insecticides（杀虫剂） that kill them.

B．How mosquitoes work is unknown to most of us.

C．Once a mosquito lands on you, it is time to bite.

D．Some bites of mosquitoes are more serious than you thought.

E. Mammals and birds give off these gases as part of their normal breathing.
F. The proteins from the saliva create an immune response from your body.
G. But if you ignore the fact that mosquitoes are so annoying they really are amazing.

Over the last 70 years, researchers have been studying happy and unhappy people and finally found out ten factors that make a difference. Our feelings of well-being at any moment are determined to a certain degree by genes. However, of all the factors, wealth and age are the top two.

Money can buy a degree of happiness. But once you can afford to feed, clothe and house yourself, each extra dollar makes less and less difference.

Researchers find that, on average, wealthier people are happier. But the link between money and happiness is complex. In the past half-century, average income has sharply increased in developed countries, yet happiness levels have remained almost the same. Once your basic needs are met, money only seems to increase happiness if you have more than your friends, neighbors and colleagues.

“Dollars buy status, and status makes people feel better,” conclude some experts, which helps explain why people who can seek status in other ways－scientists or actors, for example－may happily accept relatively poorly-paid jobs.

In a research, Professor Alex Michalos found that the people whose desire－not just for money, but for friends, family, job, health－rose furthest beyond what they already had, tended to be less happy than those who felt a smaller gap(差距). Indeed, the size of the gap predicted happiness about five times better than income alone. “The gap measures just blow away the only measures of income.” Says Michalos.

Another factor that has to do with happiness is age. Old age may not be so bad. “Given all the problems of aging, how could the elderly be more satisfied?” asks Professor Laura Carstensen.

In one survey, Carstensen interviewed 184 people between the ages of 18 and 94, and asked them to fill out an emotions questionnaire. She found that old people reported positive emotions just as often as young people, but negative emotions much less often.

Why are old people happier? Some scientists suggest older people may expect life to be harder and learn to live with it, or they’re more realistic about their goals, only setting ones that they know they can achieve. But Carstensen thinks that with time running out, older people have learned to focus on things that make them happy and let go of those that don’t.

“People realize not only what they have, but also that what they have cannot last forever,” she says. “A goodbye kiss to a husband or wife at the age of 85, for example, may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20.”

1.According to the passage, the feeling of happiness __________.

A．has little to do with wealth B．increases gradually with age

C．is determined partly by genes D．is measured by desires

2.Some actors would like to accept poorly-paid jobs because the jobs ____________.

A．make them feel much better B．improve their social position

C．provide chances to make friends D．satisfy their professional interests

3.Aged people are more likely to feel happy because they are more _________.

A．optimistic B．successful C．practical D．emotional

4.Professor Alex Michalos found that people feel less happy if __________.

A．the gap between reality and desire is bigger

B．they have a stronger desire for friendship

C．their income is below their expectation

D．the hope for good health is greater
