Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."

Knowing how much her own children loved presents at Christmas, Ann Sutton always tried to seek help for one or two poor families．With a social worker mother, the Sutton children had inherited her commitment to service, and knew never to take their good fortune at Christmas for granted． This year, Kinzie, her seven-year-old daughter was thrilled that Santa Claus would make a special visit to a 22-year-old mother named Ashley who worked in a factory raising her 12-month-old son by herself．
The phone rang on Sunday．A representative from a local organization was calling to say that the aid Ann had requested for Ashley had fallen through．No Santa Claus, no presents, nothing．
Ann saw the cheer vanish from her children’s faces at the news．Without a word, Kinzie ran into her bedroom．She returned, her face set with determination．Opening up her piggy bank, she put all the coins onto the table: $3.30．Everything she had.
“Mom,” she told Ann, “I know it’s not much．But maybe this will buy a present for the baby.”
At a breakfast meeting the next day, Ann told her coworkers about her daughter’s story．To her surprise, staff members began to open their purses and empty their pockets to help Kinzie．By day’s end, the story of Kinzie’s gift had spread beyond Ann’s office．She received a call from an unknown donor．If a seven-year-old could give everything she had, he said, he should at least match her gift 100 to 1．He contributed $300．
On Christmas Eve, Ann drove through the pouring rain to the small trailer where the Ashleys lived．Then she began to unload the gifts from the car, handing them to Ashley one by one．
Ashley was very moved．Reflecting on a little girl’s generosity, Ashley says she’ll one day be able to do something similar for someone else in need．“Kinzie could have used that money for herself, but she gave it away,” Ashley says．“She’s the type of kid I’d like my son to grow up to be.”

The medical world is gradually realizing that the quality of the environment in hospitals may play a significant role in the process of recovery from illness.
As part of a nationwide effort in Britain to bring art out of the galleries(画廊) and into public places, some of the country’s most gifted artists have been called in to change older hospitals and to soften the hard edges of modern buildings. Of the 2,500 National Health Service hospitals in Britain, almost 100 now have significant collections of modern art in corridors(走道), waiting areas and treatment rooms.
These recent initiatives(new plans) owe a great deal to one artist, Peter Senior, who set up his studio at a Manchester Hospital in Northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience.
A common hospital waiting room might have as many as 5,000 visitors each week. What a better place to hold regular exhibitions of art and paintings, in the outpatients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain’s first hospital artist, Senior was so much in demand that he was soon joined by a team of six young art school graduations.
The effect is striking. Now in the corridors and waiting rooms, the visitor experiences a full view of fresh colors, playful images and restful courtyard.
The quality of the environment may reduce the need for expense when a patient is recovering from an illness. A study has shown that patients who had a view onto a garden needed half the number of strong painkillers compared with patients who had no view at all or only a brick wall to look at.
67. What does the author mean by using the phrase “to soften the hard edge of modern buildings” in the second paragraph?
A. To hold exhibitions of art and paintings in hospitals.
B. To tear down the old hospital and build a new one.
C. To decorate hospitals with art collection.
D. To paint the walls of hospitals in soft colors.
68 What is true about Peter Senior?
A. A famous doctor in Manchester Hospital and a gifted artist.
B. Britain’s first hospital artist and a patient in Manchester Royal Hospital.
C. One of the six young art school graduations.
D. A gifted artist and a pioneer introducing art into hospitals.
69. According to Peter Senior, we can infer that________.
A. modern hospitals have a lot of patients
B. art is not appreciated by a large number of people in modern society
C. patients should be encouraged to learn painting
D. artists can not find their positions in modern society
70. What does the last paragraph suggest?
A. The improvement of hospital environment may help the patients recover from illness.
B. The improvement of hospital environment may cost the patients more than before.
C. The patients needed no painkillers when they had a view of a painting.
D. The patients had no pain at all after the improvement of hospital environment.

Would you eat a ready meal from the fridge rather than cook from scratch? Have you been doing internet shopping rather than going to the stores? What can't you be bothered to do?
A study into how lazy British people are has found more than half of adults are so idle they'd catch the lift rather than climb two flights of stairs.
Just over 2000 people were quizzed by independent researchers at Nuffield Health, Britain's largest health charity. The results were startling.
About one in six people surveyed said if their remote control was broken, they would continue watching the same channel rather than get up.
More than one third of those questioned said they would not run to catch a bus. Worryingly, of the 654 respondents with children, 64% said they were often too tired to play with them.
This led the report to conclude that it's no wonder that one in six children in the UK are classified as obese before they start school.
Dr Sarah Dauncey, medical director of Nuffield Health, said: "People need to get fitter, not just for their own sake, but for the sake of their families, friends and evidently their pets too.
"If we don't start to take control of this problem, a whole generation will become too unfit to perform even the most rudimentary of tasks."
And Scotland’s largest city, Glasgow, was shamed as the most idle city in the UK, with 75% questioned admitting they do not get enough exercise, followed closely by Birmingham and Southampton, both with 67%.
The results bring serious challenges for the National Health Service, where obesity-related illnesses such as heart disease and cancer have been on a steady increase for the past 40 years and are costing billions of pounds every year.
59.How many people questioned don’t play with their children?
A.1280.B.More than 333. C.654.D.About 420.
60.The study leads us to believe that _______.
A. the pets in the UK will be in trouble if their owners keep their way of life
B. Glasgow people feel ashamed because they don’t get enough exercise
C. British people are the laziest around the world
D. five sixths of the British children are healthy
61. How does the author convince the readers?
A. By presenting the results of a study. B. By providing answers to questions.
C. By interviewing some experts. D. By telling a story.
62. What is the passage mainly about?
A. A study of British people’s laziness. B. A study of British people’s lifestyles.
C. The health service in the UK. D. The obesity problem in the UK.

Telepathy is the ability to communicate without the use of the five senses. It’s an instinct which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we’re using resources within the unconscious（无意识的）mind. When the resources of two persons’ unconscious minds link together into the same frequency（频率）, we call it telepathy.
We can either send or receive telepathy. If you know who is calling before you answer the ringing phone, you are probably a good receiver. If you think of a person and he/she calls you, you are most likely to be better at sending.
You can easily put your ability to the test. Thinking of somebody and wish him or her to contact（联系）you. Be patient. The other person may not be a good receiver, but they should contact you much earlier than would normally be expected. Or whenever the phone rings, try ‘feeling’ who is contacting you. Don’t guess, but try to feel it with your mind. However, if neither of these works for you, that doesn’t mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.
Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other’s unconscious mind.
Telepathy & relationship. The more people spend time together, the more likely they are to be able to link up to the other’s mind, especially when separated. There are two reasons for this. One is that they understand the other’s mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child’s eagerly wanting his or her mother, knowing that this is the person who would always want to be there for them, and the mother’s deep desire to protect her child from harm.
55. When does telepathy occur?
A. It occurs when one senses that a close friend of his/her is in danger.
B. It occurs when one has very good five senses.
C. It occurs when one wants to call his/her best friend.
D. It occurs when one doesn’t know a stranger.
56. Which of the following can be used as the title of the passage?
A. Receiving Telepathy B. Telepathy: Mind-to-Mind Contact
C. Telepathy: People’s Dream D. Dream of Telepathy
57. Which of the following is true according to the passage?
A. The more people separate, the more likely that telepathy will occur.
B. It is by using the five senses that telepathy occurs.
C. Telepathy happens when people live far away and have no chance to see one another.
D. One is better at sending than receiving telepathy if one receives a friend’s call as one wishes.
58. Which of the following belongs to telepathy?
A. By accident, you are aware of a friend of yours is coming to see you.
B. People’s communication over the telephone.
C. A mother’s sense of her child is in danger.
