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 times 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.”

Over the past few decades, more and more countries have opened up the markets, increasingly transforming the world economy into one free-flowing global market. The question is：Is economic globalization   50  for all?
According to the World Bank, one of its chief supporters, economic globalization has helped reduce   51  in a large number of developing countries. It quotes one study that shows increased wealth   52  to improved education and longer life in twenty-four developing countries as a result of integration (融合) of local economies into the world economy. Home to some three billion people, these twenty-four countries have seen incomes   53  at an average rate of five percent—compared to two percent in developed countries.
Those who   54  globalization claim that economies in developing countries will benefit from new opportunities for small and home-based businesses.   55 , small farmers in Brazil who produce nuts that would originally have sold only in   56  open-air markets can now promote their goods worldwide by the Internet.
Critics take a different view, believing that economic globalization is actually   57  the gap between the rich and poor. A study carried out by the U.N.-sponsored World Commission on the Social Dimension of Globalization shows that only a few developing countries have actually   58  from integration into the world economy and that the poor, the uneducated, unskilled workers, and native peoples have been left behind.   59 , they maintain that globalization may eventually threaten emerging businesses. For example, Indian craftsmen who currently seem to benefit from globalization because they are able to   60  their products may soon face fierce competition that could put them out of   61 . When large-scale manufacturers start to produce the same goods, or when superstores like Wal-Mart move in, these small businesses will not be able to   62  and will be crowded out.
One thing is certain about globalization—there is no   63 . Advances in technology combined with more open policies have already created an interconnected world. The   64  now is finding a way to create a kind of globalization that works for the benefit of all.                                                  (347 words)

Go ahead，talk to your dog.
As many a dog owner will prove, our furry friends are listening. Now, for the doubters, there is scientific proof that they understand much of what they hear. A border collie called Rico can fetch at least 200 objects by name， researchers in Germany say. The dog also appears to learn words for new objects as easily as a 3-year-old child would. Its word-learning skill is as good as that of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them randomly into 20 sets of 10 objects each. The dog waited with one of his owners in one room, while an experimenter put a set of 10 objects into another room. Then, the owner told the dog to fetch one of the items. The dog had to go to the other room and bring the object back.
In four trials, Rico got 37 out of 40 commands right. Because the dog couldn't see anyone to get visual clues about what to bring back, the scientists concluded that he must understand the meanings of certain words.
In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names he already knew. The dog's owner then told him to fetch the object, using a word Rico had never heard.
In 7 out of 10 trials, Rico picked the right object, suggesting that he figured out the answer by process of elimination. A month later, he remembered half of the new names, which further impressed the researchers.
Rico is probably smarter than the average dog, the scientists say. For one thing, he's a border collie, a breed known for its mental abilities. In addition, the 9-year-old dog has been trained to retrieve toys by their names since he was 9 months old.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your pup every now and then. You might just get a big, wet kiss in return!

A．Rico is probably cleverer than the average dog
B．Only a few dogs can talk back to its owner

D．All dogs can understand words
50．How long is it since Rico’s owner began to train him?
A．nine months  B．3years    C．over nine years      D．more than eight years
51．Rico can do all the following except _____
A．understanding the meanings of certain words.
B．picking the right object by process of elimination
