Boris Worm of Dalhousie University in Nova Scotia, Canada, led the international team that did the study. Professor Worm says species have recently been disappearing from oceans at increasing speed. At this rate, he says, all seafood species could collapse by 2048 and seafood supplies from the world’s ocean could be almost gone by then.
Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty in fifty years. Some scientists said parts of the world do have problems, but others are doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
The study appeared earlier this month in Science magazine.
The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appeared to increase the risk of fish kills and beach closures from harmful algae growth.
The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization for nineteen fifty to two thousand three. And they examined archeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
Boris Worm says the findings were, in his words, "beyond anything we suspected." But he also said the situation is not too late to correct. He said that with good fisheries management, some species could completely recover in three to ten years. Which of the following isn’t the damage to the ocean?
| A．The species of fish in the ocean are reducing. |
| B．Sea water is polluted. |
| C．Sea water quality is improved. |
| D．Less productivity of ecosystem. |
The conclusion of the research led by Boris Worm is _________.
| A．unbearable | B．unbelievable |
| C．doubtful | D．Convincing |
The research led by Boris Worm _________.
| A．was conducted by scientists from Canada |
| B．referred to information of many countries |
| C．lasted from 1950 to 2003 |
| D．referred to records dating back to over 1,000 years ago. |
Which of the following statements is NOT true?
| A．It’s too late to take action to improve the situation. |
| B．Some species will recover with efforts. |
| C．Boris Worm hopes that people take the warning serious. |
| D．Boris Worm shows great concern about ecosystem. |
John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(消费者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.Most people usually use the GPS system for ______.
| A．driving their cars |
| B．telling the position |
| C．mending the car |
| D．supplying the sunshine |
The farmers in Ohio use GPS to ______.
| A．check if the soil is fertile in some areas |
| B．control the rain of the place |
| C．water the crops if the weather is dry |
| D．draw the map of all the crops |
Why did Ohio farmers produce more corn?
| A．Because they expanded more land to grow corn |
| B．Because they turned to technological advances |
| C．Because they used more and more fertilizer. |
| D．Because they supplies themselves with more money. |
From the passage, we can know _____.[
| A．John Davis hadn’t expected a good harvest. |
| B．farmers grew less land than in the 1930s |
| C．improved seeds cost much more money |
| D．the output of corn in the same field is increased. |
Shakespeare, more perhaps than any other writer, made full use of the greatest resources of the English Language．Most of us use about five thousand words in our normal employment of English; Shakespeare in his works used about twenty-five thousand! There is probably no better way for a foreigner to appreciate the richness and variety of the English language than by studying the various ways in which Shakespeare uses it．Such a study is well worth the effort, even though some aspects of English usage, and the meaning of many words, have changed since Shakespeare’s day．
However, it is surprising that we should know comparatively little about the life of the greatest English author．We know that Shakespeare was born in 1564 in Stratford-on-Avon, and that he died there in 1616．He almost certainly attended the Grammar School in the town, but of this we cannot be sure．We know he was married there in 1582 to Anne Hathaway and that he had three children．We know that he spent much of his life in London writing his masterpieces．But this is almost all that we do know．
However, what is important about Shakespeare’s life is not its incidental details but its products, the plays and the poems．For many years scholars have been trying to add a few facts about Shakespeare’s life to the small number we already possess and for an equally long time critics have been theorizing about the plays．Sometimes, indeed, it seems that the poetry of Shakespeare will disappear under the great mass of comment that has been written upon it．
Fortunately this is not likely to happen．Shakespeare’s people have long delighted not just the English but lovers of literature everywhere, and will continue to do so after the scholars and critics and all their works have been forgotten．This passage is about ．
| A．the great length of each chapter |
| B．the great varieties in writing styles |
| C．the richness of the content in Shakespeare’s works |
| D．the rich English language used by Shakespeare in his works |
According to the writer, which of the following remains uncertain about Shakespeare?
| A．His date of birth |
| B．His marriage |
| C．His life in the Grammar School |
| D．His date of death |
It can be inferred from Para 3 that
| A．not all the comments on Shakespeare’s works have produced good effects |
| B．scholars have successfully collected facts about Shakespeare’s life |
| C．critics are more interested in Shakespeare’s play than his poetry |
| D．the details of Shakespeare’s life are more important than his literary works |
What does the last sentence in Para 3 mean ?
| A．People don’t think the poetry of Shakespeare good any more． |
| B．People pay more attention to the comment than the poetry of Shakespeare． |
| C．People can’t see the poetry of Shakespeare any more． |
| D．The comment is printed on the poetry of Shakespeare． |
While watching the Olympics the other night, I came across an unbelievable sight．It was not a gold medal, or a world record broken, but a show of courage．
The event was swimming and started with only three men on the blocks．For one reason or another, two of them false started, so they were disqualified．That left only one to complete．It would have been difficult enough, not having anyone to race against, even though the time on the clock is important．
I watched the man dive off the block and knew right away that something was wrong．I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality．When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle．The crowd started to laugh．Clearly this man was not a medal competitor．
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time．Finally he made his turn to start back．It was pitiful．He made a few desperate strokes and you could tell he was worn out．
But in those few awful strokes, the crowd had changed．
No longer were they laughing, but beginning to cheer．Some even began to stand and shout “Come on, you can do it!” and he did．
A clear minute past the average swimmer, this young man finally finished his race．The crowd went wild．You would have thought that he had won the gold, and he should have．Even though he was recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors．
Just a short year ago, he had never even swum, let alone race．His country had been invited to Sydney．
In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog．From the passage we can learn that the young man ________
| A．made his turn to start back pitifully |
| B．was skillful in freestyle in the game |
| C．swam faster than the average swimmer |
| D．was not capable enough to win the medal |
The crowd changed their attitudes because ________
| A．they felt sorry for the young man |
| B．they were moved by the young man |
| C．they wanted to show their sympathy |
| D．they meant to please the young man |
According to the passage, “it is nice to watch an underdog” probably means _______．
| A．it’s amusing to watch a man with awful swimming skills |
| B．it’s amazing to watch an ordinary man challenging himself |
| C．it’s cheerful for athletes to act proudly before their competitors |
| D．it’s brave enough for some athletes to remove the silver medals |
What’s the best title for the passage?
| A．Compete for Gold! |
| B．Try again! |
| C．Break a Record! |
| D．Go for it! |
(The Guardian)More UK universities should be profiting from ideas
A repeated criticism of the UK's university sector is its noticeable weakness in translating new knowledge into new products and services.
Recently, the UK National Stem Cell Network warned the UK could lose its place among the world leaders in stem cell research unless adequate funding and legislation could be assured, despite an annual £40m spent by the Department of Health on all kinds of research.
However, we do have to challenge the unthinking complaint that the sector does not do enough in taking ideas to market. The most recent comparative data on the performance of universities and research institutions in Australia, Canada, USA and UK shows that, from a relatively weak starting position, the UK now leads on many indicators of commercialization activity.
When viewed at the national level, the policy interventions (interference) of the past decade have helped transformed the performances of UK universities. Evidence suggests the UK's position is much stronger than in the recent past and is still showing improvement. But national data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the back of the pack, a few perform strongly and the rest chase the leaders.
This type of uneven distribution is not strange to the UK and is mirrored across other economies. In the UK, research is concentrated: less than 25% of universities are receiving 75% of the research funding. These same universities are also the institutions producing the greatest share of PhD graduates, science citations, patents and license income. The effect of policies generating long-term resource concentration has also created a distinctive set of universities which are research-led and commercially active. It seems clear that the concentration of research and commercialization work creates differences between universities.
The core objective for universities which are research-led must be to maximize the impact of their research efforts. Their purpose is not to generate funds to add to the bottom line of the university or to substitute other income streams. Rather, these universities should be generating the widest range of social, economic and environmental benefits. In return for the scale of investment, they should share their expertise (expert knowledge or skill) in order to build greater confidence in the sector.
Part of the economic recovery of the UK will be driven by the next generation of research commercialization spilling out of our universities. On the evidence presented in my report, there are three dozen universities in the UK which are actively engaged in advanced research training and commercialization work.
If there was a greater coordination（协调）of technology transfer offices within regions and a simultaneous (happening at the same time) investment in the scale and functions of our graduate schools, universities could, and should, play a key role in positioning the UK for the next growth cycle.
What does the author think of UK universities in terms of commercialization?
| A．They have lost their leading position in many ways. |
| B．They still have a place among the world leaders. |
| C．They do not regard it as their responsibility. |
| D．They fail to change knowledge into money. |
What does the author say about the national data on UK universities’ performance in
commercialization?
| A．It masks the fatal weaknesses of government policy. |
| B．It indicates their ineffective use of government resources. |
| C．It does not rank UK universities in a scientific way. |
| D．It does not reflect the differences among universities. |
We can infer from Paragraph 5 that “policy interventions (in Paragraph 4)” refers to _____.
| A．concentration of resources in a limited number of universities |
| B．compulsory cooperation between universities and industries |
| C．government aid to non-research-oriented universities |
| D．fair distribution of funding for universities and research institutions |
What dose the author suggest research-led universities do?
| A．Fully use their research to benefit all sectors of society. |
| B．Generously share their facilities with those short of funds. |
| C．Advertise their research to win international recognition. |
| D．Spread their influence among top research institutions. |
Rae and Bruce Hostetler not only work very hard,they also relax just as well. Numerous vacations help the couple to maintain their health and emotional well-being一and it’s no surprise to health care professionals.
“Rest, relaxation, and stress reduction are very important for people’s well-being and health. This can be accomplished through daily activities, such as exercise and meditation, but vacation is an important part of this as well,” said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off. “We also know that the mind is very powerful and can help with healing, so a rested, relaxed mind is able to help the body heal better,” said Withers.
Psychologists confirm the value of vacations for the mind. “The impact that taking a vacation has on one’s mental health is great,” said Francine Lederer, a clinical psychologist in Los Angeles who specializes in stress and relationship management. “Most people have better life perspective and are more motivated to achieve their goals after a vacation, even if it is a 24- hour time-out.” The trips could be good for their health, good for their family and good for their businesses.
The online travel agency Expedia conducted a survey about vacation time in 2010, and according to their data the average American earned 18 vacation days一but only used 14 of them. France topped the list, with the average worker earning 37 vacation days and using all but two of them. Americans’ responses may not be surprising in a culture where long hours on the job often are valued, but that’s not always good for the individual, the family or the employer.
Psychologists have also found that people who don’t take enough time to relax may find it harder to relax in the future. “Without time and opportunity to do this, the nerve connections that produce feelings of calm and peacefulness become weaker, making it actually more difficult to shift into less-stressed states,” Mulhem said.How did the author introduce the topic of the text?
| A．By making comparisons. | B．By giving an example. |
| C．By raising questions. | D．By providing data. |
Expedia’s survey shows that Americans _____.
| A．dislike family gatherings |
| B．have the shortest vacation |
| C．enjoy as many vacations as the French |
| D．think much of spending long hours on the job |
What can be inferred from the last paragraph?
| A．One should never wait to relax. |
| B．Work and rest go against each other. |
| C．Time and opportunity wait for no man. |
| D．A relaxed mind determines everything. |
