      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."

1. What can be the best title of the passage?

[ ]

A. Sea Life Facing Danger
B. Scientist Researching Seawater
C. Oceans Becoming More Acidic
D. Climate Change Affecting Seawater

2. Which of the following shows the process of the impact of atmospheric CO2 on sea life?
    a. Sea life is endangered.
    b. CO2 goes into the surface water.
   c. The ocean chemistry is affected.
    d. CO2decreases the PH and makes the seawater more acidic.
    e. CO2 levels in the atmosphere go up.

[ ]

A. a-b-c-d-e
B. e-b-c-d-a
C. a-e-b-c-d
D. e-d-c-b-a

3. Scientist Robert Dore came to the conclusion based on ______.

[ ]

A. his research and analysis
B. the expectation of other scientists
C. some former theory
D. a major cause of climate change

4. What does the passage want to tell us most?

[ ]

A. It takes time to make a scientific study.
B. Atmospheric CO2 is doing harm to sea life.
C. Robert Dore is a committed and serious scientist.
D. Measures should be taken to prevent the potential catastrophe.

　　Two year s ago, Wendy Ha snip, 47，experienced a brain injury that left her speechle s s for two week s．When she finally recovered, she found her self talking with what seemed to be a French accent．“I phoned a friend the other day, and she spent the fir st ten minute s laughing, ” Ha snip said at the time, “while I have nothing again st the French．”

　　Ha snip suffered from foreign accent syndrome(外国口音综合症), a rare condition in which people find them selve s speaking their own language like someone from a foreign country．The condition u sually occur s in people who have experienced a head injury or a stroke-a sudden lo s s of con sciou sne s s, sen sation, or movement cau sed by a blocked or broken blood ve s selin the brain．

　　The condition wa s fir st identified during the Second World War in a Norwegian woman who se head wa s injured during an attack by the German military．The woman recovered but wa s left with a German-sounding accent, to the horror of fellow villager s who avoided her after that．

　　Re searcher s have di scovered that the combined effect of the damage to several part s of the brain make s victim s lengthen certain syllable, mi spronounce sound s, and change the normal pitch(音高)of their voice．Tho se change s in speech add up to what sound s like a foreign accent．

　　Another re searcher, a phonetician, say s victim s of the syndrome don't acquire a true foreign accent．Their strangely changed speech only re semble s the foreign accent with which it ha s a few sound s in common．

　　When an Engli sh woman named Annie recently developed foreign accent syndrome after a stroke, she spoke with what seemed to be a Scotti sh accent．However, Annie' s Scotti sh coworker s said she didn't sound at all like a Scot．
