“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

Lee Ann Laraway has polio (小兒麻痹癥) and is not able to move very much. Most things are out of reach for her. Jeannie, a Labrador retriever, acts as her arms and legs. Jeannie understands 72 or more different commands. On a shopping trip, she can get money for Lee Ann at the bank or candies at the store. She can pay the cashier (收銀員) and get change back. Jeannie brings things to Lee Ann and puts them in her lap.
Jeannie was trained at a place called Canine Companions for Independence, located on twelve acres of land in Santa Rosa (California). The land was donated (捐贈) by the cartoonist Charles Shultz. “We train four different types of dogs here,” said Ken Kirsh, a dog trainer there. “Hearing dogs, service dogs, skilled companion dogs, and facility dogs.”
Trainers work with Labrador retrievers and golden retrievers for hours a day, but not every dog is good enough to be a working dog.
The work is a serious business. Hearing dogs warn their owners of sounds like ringing telephones and doorbells. Other dogs work with disabled patients like eight-year-old Noah Habib who communicates with a special computer. He likes it when people come to ask him about his dog. His father says, “People are really interested in the dog and will come over and ask to pet her and play with her, and ask about what she does, and these are people that normally might not approach us and want to talk to Noah.”
When Lee Ann Laraway comes home with Jeannie and her goods, Jeannie helps her open the door. “You can train a dog to do a lot of things.” said Lee Ann.
【小題1】According to this passage, we can know that Jeannie is Lee Ann’s .
A.servant | B.daughter | C.dog | D.mother |
A.go to the bank to get money |

Many people write to newspaper and magazines to express their opinions. Letters to the editor must carry the writer’s full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are held responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.
“People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
There are people who wish to remain anonymous(匿名的)for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter if responsibility to use it when we make a statement, a claim or an accusation. We all want to honour our own name, and it is only by stamping our expression of an opinion with our own name that we honour what we say.
【小題1】What does the writer mean by saying “Responsibility is the name of the game”?
A.Writers need to provide their personal information in the game. |
B.Publication must bear the writer’s full name, address and phone number. |
C.Writers should be responsible for their names. |
D.Names are required to indicate writers’ responsibility for what they say. |
A.help to end a relationship | B.not get a reply |
C.be accepted all the same | D.become a family problem |
A.hesitant to make a donation | B.unwilling to draw public attention |
C.afraid of an accusation | D.ready for involvement |
A.honour and writers | B.identity and signature |
C.signature and responsibility | D.anonymity and signature |

Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.
WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.
Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.
"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.
Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."

4. What can we learn from the passage?
A. The volcanic ash wouldn’t be harmful to people.
B. All experts thought the volcanic ash did great harm to our health.
C. People close to the volcano would likely be at risk according to some experts.
D. Europeans should stay indoors because Iceland's volcano starts settling.
