“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多种维生素make you healthier?
“We believe that the case is closed - supplementing(补充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(认知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰剂)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.This text is likely to be selected from a book of .

Almost all cultures celebrate the end of one year and the beginning of another in some way. Different cultures celebrate the beginning of a new year in different ways, and at different times on the calendar.
In Western countries, people usually celebrate New Year at midnight on January 1st. People may go to parties, dress in formal clothes -- like tuxedos (小礼服) and evening gowns, and drink champagne at midnight. During the first minutes of the New Year, people cheer and wish each other happiness for the year ahead. But some cultures prefer to celebrate the New Year by waking up early to watch the sun rise.

The doll is filled with old newspapers and firecrackers. At midnight, these dolls are burned to show the bad things from the past year are gone and the new year can start afresh (again). Other common traditions to keep away bad luck in a new year include throwing things into rivers or the ocean, or saying special things on the first day of the new year.

I have a friend named Monty Roberts who owns a horse ranch in San Ysidro. He has let me use his house to put on fund-raising events to raise money for youth at risk programs．
The last time I was there he introduced me by saying, "I want to tell you why I let Jack use my house.” It all goes back to a story about a young man who was the son of a horse trainer who would go from stable to stable, race track to race track, farm to farm and ranch to ranch, training horses. As a result, the boy's high school career was continually interrupted. When he was a senior, he was asked to write a paper about what he wanted to be and do when he grew up.”
That night he wrote a seven-page paper describing his goal of someday owning a horse ranch．He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings, the stables and the track. Then he drew a detailed floor plan for a 4,000-square-foot house that would sit on a 200-acre dream ranch．”
He put a great deal of his heart into the project and the next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a

Aimlessness has hardly been typical of the postwar Japan whose productivity and social harmony are the envy of the United States and Europe. But increasingly the Japanese are seeing a decline of the traditional work-moral values. Ten years ago young people were hardworking and saw their jobs as their primary reason for being, but now Japan has largely fulfilled its economic needs, and young people don't know where they should go next.
The coming of age of the postwar baby boom and an entry of women into the male-dominated job market have limited the opportunities of teenagers who are already questioning the heavy personal sacrifices involved in climbing Japans rigid social ladder to good schools and jobs. In a recent survey, it was found that only 24.5 percent of Japanese students were fully satisfied with school life, compared with 67.2 percent of students in the United States. In addition, far more Japanese workers expressed dissatisfaction with their jobs than their counterparts did in the ten other countries surveyed.
While often praised by foreigners for its emphasis on the basics, Japanese education tends to stress test taking and mechanical learning over creativity and self-expression." Those things that do not show up in the test scores, personality, ability, courage or humanity are completely ignored," says Toshiki Kaifu, chairman of the ruling Liberal Democratic Party's education committee." Frustration against this kind of thing leads kids to drop out and run wild." Last year Japan experienced 2,125 incidents of school violence, including 929 assaults on teachers. Amid the outcry, many conservative leaders are seeking a return to the prewar emphasis on moral education. Last year Mitsuo Setoyama, who was then education minister, raised eyebrows when he argued that liberal reforms introduced by the American occupation authorities after World WarⅡ had weakened the "Japanese morality of respect for parents."
But that may have more to do with Japanese life-styles." In Japan," says educator Yok
o Muro, "it’s never a question of whether you enjoy your job and your life, but only how much you can endure." With economic growth becoming centralization, fully 76 percent of Japans, 119 million citizens live in cities where community and the extended family have been abandoned in favor of isolated, two generation households. Urban Japanese have long endured lengthy commutes (travels to and from work) and crowded living conditions, but as the old group and family values weaken, the discomfort is beginning to tell. In the past decade, the Japanese divorce rate, while still well below that of the United States, has increased by more than 50 percent, and suicides have increased by nearly one-quarter. In the Westerners eyes, the postwar Japan was_____ .
| A．under aimless development | B．a positive example |
| C．a rival to the West | D．on the decline |
According to the author, what may chiefly be responsible for the moral decline of Japanese society?

| D．The life-style has been influenced by Western values. |
Which of the following is true according to the author?
| A．Japanese education is praised for helping the young climb the social ladder. |
| B．Japanese education is characterized by mechanical learning as well as creativity. |
C．More stress should be placed on the cultivation of creativity. |
| D．Dropping out leads to frustration against test taking. |

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.www.examda.com
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays.
This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.Which of these sentences best describes the writer's point in Paragraph 1?
| A．To some extent, intelligence is given at birth. |
| B．Intelligence is developed by the environment. |
| C．Some people are born clever and others born stupid. |
| D．Intelligence is fixed at birth, but is developed by the environment. |
It is suggested in this passage that_______.
| A．unrelated people are not likely to have different intelligence |
| B．close relations usually have similar intelligence |
| C．the closer the blood relationship between people, the more different they are likely to be in intelligence |
| D．people who live in close contact with each other are not likely to have similar degrees of intelligence |
Brothers and sisters are likely to_______.
| A．have similar intelligence | B．have different intelligence |
| C．go to the same university | D．go to the same factory |
The best title for this article would be_______.
| A．On Intelligence | B．What Intelligence Means |
| C．We Are Born with Intelligence | D．Environment Plays a Part in Developing Intelligence |
It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’ m so glad I did.
On the way to the harbor we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape．After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it — there weren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale—actually as big as our boat—was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools（漩涡） and waves. "She’s trying to help her baby, but on the wrong side," my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, sometimes rising from the water right beside us to breathe—and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off. They swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day.
