“The world's oceans are slowly getting more acidic.” say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
The lowering of the waters' PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.
These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. “This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira. And we predict the amount of future acidity will exceed(超過) anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.
However, it is not absolutely clear what that means for ocean life. Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep-ocean life forms may be more sensitive to PH changes. Coral reefs(珊瑚礁) and other organisms whose shells contain calcium carbonate(碳酸鈣) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower PH.
In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming. But Dr Caldeira said that such a strategy should now be re—considered. “Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing——because in releasing CO2 into the atmosphere we warm the planet, and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.”
57.The ocean is becoming more acidic due to_______.
A.the lower water PH value B.the warming atmosphere
C.the higher level of CO2 in the air D.the increasing use of oil fuels
58.According to Dr Caldeira,________.
A.ocean absorption of carbon dioxide is a good thing
B.more oil fuels will be used in the near future
C.scientists may predict climate changes with computer models
D.the future situation of the amount of acidity is extremely serious
59.If the water's acidity level keeps rising,____________.
A.ocean life whose structures contain calcium carbonate may be affected
B.the water's PH value will become higher and higher
C.organisms living near the surface are more sensitive to PH changes
D.some disastrous events will occur more often than before
60.Most experts once believed storing carbon dioxide in the ocean would reduce_________
A.the CO2 absorbed by the ocean B. the amount of greenhouse warming
C.the acidity of the ocean D.the gradual release of CO2

B
I believe that it is important to be brought up with a firm belief in the good. I was fortunate in this respect. My parents not only gave me a happy home, but they had me study half a dozen foreign languages and made it possible for me to travel in other countries. This made me more tolerant and helped me to bridge many difficulties in later life.
Soon after I got married, my husband and I left our native Czechoslovakia and went to live in Shanghai, China. Here was a really international city. People of all races and beliefs lived and worked together.
In Shanghai, in 1941, when I was only twenty years old, the doctors discovered that I had diabetes. It was a terrible shock, because diabetes is incurable. But it can be controlled by insulin (胰島素). Although this drug was not manufactured in China, there were enough stocks of imported insulin available. This enabled me to continue a normal, happy life.
Then bombs fell on Pearl Harbor and the Japanese occupied Shanghai. The import of insulin was cut off. Before long, there was not enough for the diabetics. I was on a starvation diet to keep my insulin requirements as low as possible. Many diabetics had already died, and the situation became desperate. In spite of all this, I never stopped believing that with the help of my husband’s love and care, I would survive.
I continued to teach in Chinese schools. My faith and my husband’s never-ending efforts to get the manufacture of insulin started gave me courage. In his small laboratory the production of insulin was attempted. I served as the human guinea pig(實驗品)on which it was tested. I’ll never forget the day when my husband gave me the first injection of the new insulin, which had worked on rabbits. It helped! Can you imagine our happiness and relief?
I received the greatest strength from the deep love and complete understanding between my husband and me. And next to that was the kindness and help of many, many friends of many nationalities. To me, the experience of living in Shanghai during the special times was unforgettable.
After the Second World War, my husband and I sailed to the Untied States, which is also known as a melt pot. Wherever we live, I believe, with faith and love, love between families and friends from different nationalities, we can make it our cherished home.
61. What can we know about the author?
A. She visited China before twenty. B. She was given an unhappy home.
C. She got married in Czechoslovakia. D. She could hardly tolerate her parents.
62. As a diabetic, the author could still live normally in 1941 because .
A. she was able to buy enough insulin B. she received good medical treatment
C. she was looked after by her husband D. she was helped by people of different races
63. The underlined word “it” in Paragraph 5 refers to .
A. a small rabbit B. an ever lasting effort C. the new insulin D. the human guinea pig
64. How does the author feel about her stay in China?
A. Unbearable. B. Unbelievable. C. Unfortunate. D. Unforgettable.
65. We can infer from the text that the author’s husband was .
A. a doctor B. a researcher C. a teacher D. a sailor

Last year, Jack Bleed cut through the bone of his ring finger while working. The 31-year-old resident of North Little Rock, Arkansas, waited for about six hours at a nearby medical center while the medical staff there called all over town — even as far away as Dallas and Memphis — to find a hand surgeon to reattach his finger. Finally, a willing doctor was located in Louisville, Kentucky. But even though Bleed had insurance (保險), he would have to hire a private plane to get himself there, at a cost of $4,300. In the end, he charged the cost to two credit cards, and his finger was saved. His insurance company eventually covered the cost of the plane, but his experience makes people aware of the fact that trauma (外傷) care in the United States is not only geographically limited, but in many places, non-existent.
Only eight states — New York, New Jersey, Maryland, Illinois, New Mexico, California, Oregon, and Washington — have local, fully functional trauma systems. The remaining states have partial systems, and 12 — including Arkansas — have no trauma system at all.
Although the President has signed a bill of $12 million for the purpose of supporting trauma care systems nationwide, many in Congress (國會) are unwilling to spend government money for a service they think should be paid for by states, says Wayne Meredith, medical director for trauma programs at the American College of Surgeons. Meanwhile, many states have also failed to find the dollars to support trauma systems. To make matters worse, many people without insurance depend heavily on the emergency care services, placing a huge financial burden on the medical centers that serve them.
For the same reason, doctors, too, often go unpaid. They are unwilling to perform emergency care, worsening critical shortages of neurosurgeons, orthopedists, and hand surgeons — the very types of specialists Bleed needed at short notice.
Supporting a trauma care system doesn’t take much. A half-penny sales tax in Miami-Dade County makes its outstanding system work. In Arkansas alone, says Wayne Meredith, a well-funded trauma system would possibly prevent 200 to 600 deaths each year. If trauma care systems were to work well across the nation, experts say, many thousands of lives each year could be saved. “You don’t get much better return on your investment than that,” Meredith says.
57. In Paragraph 1, the writer uses Bleed’s case to ________.
A. make a comparison
B. introduce a topic
C. describe a person
D. tell a story
58. Many people in Congress argue that trauma care systems should be supported by ________.
A. each state
B. the President
C. insurance companies
D. the US government
59. The example of Miami-Dade County shows that ________.
A. its tax policy is admirable
B. a trauma system is not expensive
C. running a trauma system is profitable
D. sales tax is not heavy in small counties
60. Why are the present trauma care systems in some states not satisfactory?
A. They are short of financial support.
B. They are shared by all the states.
C. The doctors are not well trained.
D. The hospitals can’t provide low-cost services.

A curriculum vitae (CV) provides an overview of a person's life and qualifications. You know that you're a star but without a knock-out CV, no-one else will believe you. Here's how to impress and write yourself into a better job.
First, be concise (簡潔的). "It's not War and Peace." says Steven Kirkpatrick, the managing director of Adecco Staffing. Recruiters (考官) who have to plough through hundreds of CVs don't enjoy flowery long articles. Use active verbs and ensure that every sentence counts.
Second, tell the truth. "The most important thing is not to lie," Kirkpatrick says. "People decorate their CV by adding things to make themselves more attractive," he says, only to embarrass themselves later. "If your first impression is a lie, it's not a great basis for moving forward."
Then, focus on your skills. A CV is a selling tool and how you break down what you have learnt and what you can do is me most important. "It's OK to simplify job titles to make them clearer," Sharman says. "Just outline your achievements and experience to back that up, and say more about your recent roles."
Also, personalize it. "There's nothing as bad as getting an automatically created CV from a website," Kirkpatrick says. "What they are buying is you, so sell them you. It's always nice to have personal information that makes you a human being," Sharman says. But do try to stand out from the crowd.
Finished? So you've written the perfect CV. That's the job half done. Last but not least, check out how to write the perfect covering letter.
