Ocean Acidification: 'Evil Twin' Threatens World's Oceans
The rise in human emissions of carbon dioxide is driving dangerous changes in the chemistry and ecosystems of the world's oceans, international marine(海洋的)scientists have warned. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," says the latest issue of the journal Trends in Ecology and Evolution. "This emphasizes the urgent need to adopt policies that markedly reduce CO2 emissions."
Ocean acidification, which the researchers call the 'evil twin of global warming', is caused when the CO2 emitted by human activity, mainly burning fossil fuels, dissolves into the oceans. It is happening independently of, but in combination with, global warming. Evidence gathered by scientists over the last few years suggests that ocean acidification could represent an equal -- or perhaps even greater threat -- to the biology of our planet than global warming. More than 30% of the CO2 released from burning fossil fuels, cement production, deforestation and other human activities goes straight into the oceans, turning them gradually more acidic.
"The resulting acidification will impact many forms of sea life, especially organisms whose shells or skeletons are made from calcium carbonate(碳化钙), like corals and shellfish. It may interfere with the reproduction of plankton species which are a vital part of the food web on which fish and all other sea life depend," he adds.
The scientists say there is now persuasive evidence that mass extinctions in past Earth history, like the "Great Dying" of 251 million years ago and another wipeout 55 million years ago, were accompanied by ocean acidification, which may have delivered the deathblow to many species that were unable to cope with it. "These past periods can serve as great lessons of what we can expect in the future, if we continue to push the acidity the ocean even further" said lead author, Dr. Carles Pelejero, from ICREA and the Marine Science Institute of CSIC in Barcelona, Spain. "Given the impacts we see in the fossil record, there is no question about the need to immediately reduce the rate at which we are emitting carbon dioxide in the atmosphere," he said further.
"Today, the surface waters of the oceans have already acidified by an average of 0.1 pH units from pre-industrial levels, and we are seeing signs of its impact even in the deep oceans," said co-author Dr. Eva Calvo, from the Marine Science Institute of CSIC in Spain. "Future acidification depends on how much CO2 humans emit from here on -- but by the year 2100 various projections indicate that the oceans will have acidified by a further 0.3 to 0.4 pH units, which is more than many organisms like corals can stand," Prof. Hoegh-Guldberg says.
"This will create conditions not seen on Earth for at least 40 million years."
"These changes are taking place at rates as much as 100 times faster than they ever have over the last tens of millions of years" Prof. Hoegh-Guldberg says. Besides directly impacting on the fishing industry and its contribution to the human food supply at a time when global food demand is doubling, a major die-off in the oceans would affect birds and many land species and change the biology of Earth as a whole profoundly, Prof. Hoegh-Guldberg adds.
67. What is the biggest cause of the ocean acidification according to the report?
A. the increase of carbon dioxide emission by human beings
B. The worsening of global warming
C. The disappearance of the world’s forests
D. The decrease of marine life
68. In what way according to the report does ocean acidification affect the majority of marine life?
A. It affects their reproduction B. It destroys their food chain
C. It affects the growth of their young D. destroys their habitats
69. Which of the following statements is NOT true about ocean acidification?
A. Ocean acidification has made ocean conditions most extreme in millions of years.
B. Ocean acidification may do more damage than global warming to human and plant life in the long run.
C. Ocean acidification is suspected of having caused mass extinctions of life in past Earth history.
D. The effects of ocean acidification are not now but will be felt in the foreseeable future.
70. From the report we can clearly feel that the situation with ocean acidification __________.
A. is quite optimistic B. remains well under control
C. looks more than urgent D. is already out of control

The research carried out by the University of Bari in Italy could help prove hospitals who are accused of wasting money on art and decoration as it suggests a pleasant environment helps patients ease discomfort and pain.
A team headed by Professor Marina de Tommaso at the Neurophysiopathology Pain Unit asked a group of men and women to pick the 20 paintings they considered most ugly and most beautiful from a selection of 300 works by artists such as Leonardo da Vinci and Sandro Botticelli. They were then asked to look at either the beautiful paintings, or the ugly painting, or a blank panel while the team zapped(照射) a short laser pulse at their hand, creating a sensation as if they had been stuck by a pin. The subjects rated the pain as being a third less intense while they were viewing the beautiful paintings, compared with when looking at the ugly paintings or the blank panel. Electrodes measuring the brain's electrical activity also confirmed a reduced response to the pain when the subject looked at beautiful paintings.
While distractions, such as music, are known to reduce pain in hospital patients, Prof de Tommaso says this is the first result to show that beauty plays a part.
The findings, reported in New Scientist, also go a long way to show that beautiful surroundings could aid the healing process.
"Hospitals have been designed to be functional, but we think that their artistic aspects should be taken into account too," said the neurologist. "Beauty obviously offers a distraction that ugly paintings do not. But at least there is no suggestion that ugly surroundings make the pain worse. " "I think these results show that more research is needed into the field how a beautiful environment can alleviate suffering."
Pictures they liked included Starry Night by Vincent Van Gogh and Botticelli’s Birth of Venus. Pictures they found ugly included works by Pablo Picasso, the Italian 20th century artist Anonio Bueno and Columbian Fernando Botero. "These people were not art experts so some of the pictures they found ugly would be considered masterpieces by the art world," said Prof de Tommaso.
1.The underlined word “alleviate” in the fifth paragraph probably means “_________”.
A. cure B. ease C. improve D. kill
2.How many artists have been mentioned in the passage?
A. 4. B. 5. C. 6. D. 7.
3.Which of the following is TURE about the view of Prof de Tommaso’s?
A. Beautiful surroundings could help to heal sufferings completely .
B. Hospitals must take their artistic aspects into consideration first.
C. Ugly surroundings will surely make the pain worse.
D. Both music and beauty can reduce pain in hospital patients.
4.Which of the following is the suitable title for the passage?
A. Beautiful surroundings can ease pain.
B. Ugly paintings could be masterpieces.
C. More research should be done in the field.
D. Latest environmental research.

Who takes care of the elderly in the United States today? Many people wrongly believe that when people reach old age, their families place them in nursing homes. They are left there in the hands of strangers for the rest of their lives. Their grown-up children visit them only occasionally, but more often, they do not have any regular visitors. Actually this is not true. In fact, family members provide over 80 percent of the care that elderly people need.
Prof. Samuel Preston, a sociologist at the University of Pennsylvania, studied how the American family is changing. He reported that by the time the average American couple reaches 40 years of age, they have more parents than children. This statistic (统计) shows the change in life-styles and responsibilities of aging Americans. The average middle-aged couple can look forward to caring for elderly parents some time after their own children have grown up. Moreover, because people today live longer after an illness than people did years ago, family members must provide long-term care. These facts also mean that after care-givers provide for their elderly parents, who will eventually die, they will be old and may require care too. When they do, their spouses (配偶, 指夫或妻) will probably take care of them.
Because Americans are living longer than ever, more psychologists and social workers have begun to study care-giving to improve care of the elderly. They have found that all caregivers share a common characteristic: all caregivers believe that they are the best person for the job, for different reasons. One caregiver said that she had always been close to her mother. Another was the oldest child. In other words, they all felt that they could do the job better than anyone else. Social workers interviewed caregivers to find out why they took on the responsibility of caring for an elderly, dependent relative. They discovered three basic reasons. Many caregivers believed that they had the responsibility to help their relatives. Some stated that helping others made them feel more useful. Others hoped that by helping someone now, they would deserve care when they became old and dependent.
48. It can be inferred that a middle-aged couple in the US _______.
A. spend more time with their children than with their parents
B. depend on their children’s assistance in caring for the elderly
C. don’t pay more attention to their children than to their parents
D. spend more time taking care of their parents than before
49. The most common characteristic of caregivers is ______.
A. they all have professional qualifications in care-giving
B. they all believe themselves to be the best caregiver
C. they are the eldest child in the family
D. they are close to their parents
50. Which of the following is NOT a basic reason for care-giving?
A. Respect from other members of the family.
B. Prepayment for the care they will get in old age.
C. A feeling of being needed and helpful.
D. A strong sense of duty to the elderly.
51. What is the main idea of this passage?
A. Most old people in the US are living a happy life.
B. Most old people in the US live longer today after an illness than people did years ago.
C. Most elderly people in the US are taken care of by their families, who often find the experience satisfying.
D. Most elderly people in the US prefer living with their families to living nursing houses.
