"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 COZ into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed（超过）anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid（小1j-%+.'_) 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 and other organisms whose shells contain calcium carbonate（小行星) 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 stations 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一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.”The ocean is becoming more acidic due to＿．
A，the lower water pH value B．the warming atmosphere
C ．the higher level of COZ in the air D．the increasing use of oil fuelsAccording 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 |
If the water's acidity level keeps rising,＿．
| A．ocean life whose structures contain calcium carbonate may be affected |
| B．the waters’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 |
Most experts once believed storing carbon dioxide in the ocean would reduce＿．
| A．the COZ absorbed by the ocean |
| B．the amount of greenhouse warming |
| C．the acidity of the ocean |
| D．the gradul release Of CO2 |
The purpose of this passage is to＿．
| A．show people the findings of a research team |
| B．inform people of how acid the ocean is now |
| C．introduce Dr Caldeira and his team's research |
| D．warn people of the higher level of COZ |
How to Be a Winner
Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes(糖尿病). Believing my career（职业生涯） was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn't finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success-you can’t follow a career in any field without being well—organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best
Poet & Writer
“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological（心理的） tool”

I was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be cancelled(取消). I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn’t care about my work, and he didn’t care about me. I was overcome with that thought. I started to shout at the phone, “Let me wait, will you? Who do you think you are?”
At that time I didn’t realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, “Yeah! Who do you think you are? Bad telephone! Bad telephone! ” And she swept it into the wastebasket.
I stood watching her, speechless .What on earth…?
She stepped to the doorway and shouted at the rest of the house, “Now hear this! All objects in this room—if you do anything to upset my husband , out you go!”
Then she turned to me, kissed me, and said calmly, “Honey, you just have to learn how to take control.” With that, she left the room.
After watching a crazy woman rushing in and out, shouting at everything in sight, I noticed that something in my mood（情绪）had changed. I was laughing. How could I have trouble with that phone? Her antics helped me realize I had been driven crazy by small things. Twenty minutes later my agent did call. I was able to listen to him and talk to him calmly.

Want to lose weight? Try eating. That’s one of the ways being developed by scientists experimenting with foods that trick the body into feeling full.
At he Institute of Food Research in Norwich, England, food expert Peter Wilde and his colleagues are developing foods that slow down the digestive system, which then sends a signal to the brain that stops appetite. “That fools you into thinking you’ve eaten far too much when you really haven’t,” said Wilde. From his studies on fat digestion, he said it should be possible to make foods, from bread to yoghurt, that make it easier to diet. While the research is still in its early stages, Wilde’s approach to controlling appetite is one that some doctors say could be a key to solving the problem of obesity.
“Being able to switch off appetite would be a big help for people having trouble losing weight,” said Steve Bloom, a professor of investigative medicine at London’s Imperial College, who is not connected to Wilde’s research. Bloom said that regulating appetite through foods is theoretically possible. But Bloom warned that controlling appetite may be very challenging. “The body has lots of things to prevent its regulatory systems from being tricked,” he said.
Wilde’s research makes use of the body’s ways of digesting fat. Fat normally gets broken down in the first part of the small intestines (肠道). When you eat a high-fat meal, however, the body can only digest the fat entirely further down in the intestines, which then causes the body to produce a kind of chemical to stop the appetite.
Wilde’s approach copies what happens with a high-fat meal. He coats fat droplets (滴) in foods with modified proteins from plants, so it takes longer for the chemical that breaks down fat to reach it. That means that the fat isn’t digested until it hits the far reaches of the intestines. At that point, intestinal cells send a signal telling the brain it’s full. Even though the body hasn’t had a high-fat meal, it stops the appetite as if it has. If the fat had been digested earlier in the intestines, no such signal would be sent.
51. According to Wilde’s research, what could people do if they want to lose weight?
A. Eat more bread and yoghurt. B. Trick the body by eating nothing.
C. Have foods with fat droplets coated. D. Control their digestive system strictly.
52. The underlined word “obesity” in Para. 2 most probably means “________”.
A. being too fat B. eating too much food
C. stopping appetite D. being unhealthy
53. What can be inferred about Professor Bloom’s opinion towards Wilde’s approach?
A. It won’t work since the body’s regulatory systems will never be tricked.
B. It is sure to switch off the appetite of people with a weight problem.
C. It sounds terrible because regulating appetite through foods is not practical at all.
D. It’s no that easy to trick the body so more research should be done.
54. Which of the following is TRUE about Wilde’s approach?
A. A kind of chemical is added to make a high-fat meal less fatty.
B. Fat is digested earlier and the body sends a signal telling the brain it’s full.
C. Fat won’t get broken down in the first part of the small intestines.
D. The chemical that breaks down fat will not reach the fat.
55. The passage is written to ________.
A. give advice on how to stop eating high-fat meals
B. introduce a research on controlling appetite
C. discuss the argument between two professors
D. show different ways to trick the body
It’s not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.
The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in new South Wales and Britain.
And they came across astounding (令人吃惊的) results – it was found that infants had “social brains” and focused not just on their mothers but on social life in groups as well.
“They communicate with more than one baby at once, and show jealousy and generousness,” said Professor Bradley.
He added, “They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers.”
“A baby who has a depressed mother tends to be withdrawn (内向的), but put that same baby in a group of its peers (同龄人)and they behave and interact like any other baby.”
It was the first all-baby group study ever to be conducted. “Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers: fathers, siblings, grandparents and those taking care. Therefore, the ‘mother-baby approach’ needs to be combined with a ‘group approach’,” said Bradley.
Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west, said she often noticed what appeared to be emotional attachments developed between toddlers.
She said, “Joel (10 months) and Isabella (11 months) always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing.”
46. Which of the following statements about the study is TRUE?
A. It’s the first study to look at all-baby groups.
B. It divides babies according to their personalities.
C. Its aim is to change the way of child care.
D. Its results are unbelievable.
47. A baby who has a depressed mother _________.
A. tends to be a follower B. also enjoys group interaction
C. has poor social ability D. pays more attention to its mother
48. What can be inferred from the result of this study?
A. Babies are affected by groups more than by their mothers.
B. There’s no need of child-care centers at all.
C. Adults should include babies when having social activities.
D. The normal infant-mother bond alone isn’t enough for the good mental health for babies.
49. The underlined word “toddlers” in Para. 8 can be replaced by “_________”.
A. adults B. infants C. peers D. groups
50. The example given in the last paragraph proves that a baby ________.
A. is born to be friendly to other babies
B. has interest in peers as well as in its mother
C. may have emotional attachments to another baby
D. shows jealousy and generousness as an adult
