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．Climate Change Affecting Seawater

C．Oceans Becoming More Acidic                     D．Scientist Researching 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．a major cause of climate change

C．some former theory

D．the expectation of other scientists

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

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．

The global financial crisis is likely to cause increased mental health problems and even suicides（自杀）as people struggle to deal with poverty and unemployment, the World Health Organization warned Thursday.

Hundreds of millions of people worldwide are already affected by mental problems such as depression and bipolar disorders (带狂躁的抑郁症) and the current market meltdown (崩溃) could worsen feelings of despair among people who can't stand such illnesses.

The United Nations agency said the impact could be especially marked for those living in low and middle income countries where access to treatment is often limited.

“We should not be surprised at the turbulence (动荡) and likely consequences of the current financial crisis. Now we are seeing a huge gap in taking care of people in great need,” WHO director general Margaret Chan told at a meeting of mental health experts.

“It should not come as a surprise that we continue to see more stresses, suicides and mental disorders,” Chan warned.

Benedetto Saraceno, director of WHO's mental health, said mental health disorders affected one in four people at some point in their lives.

Mental and neurological disorders are often chronic (慢性的) and disabling, he said. Nearly 1 million people commit suicide worldwide every year, a large proportion (比例) of them are young adults.

Asked about the financial crisis, Saraceno said, “Poverty can be the consequence of such events, the debts, despair and sense of loss that may reach middle and lower classes. Even the poor can be affected by this crisis.”

“There is a clear evidence that suicide is linked to financial disasters. I am not talking about the millionaire's jumping out of the window but about poor people,” he said. The global crisis could be expected to affect the “stability（稳定）of communities and families”, according to Saraceno.

67．According to the passage, the chief result of the worldwide financial crisis is that  ________ .

A．more people will be poorer

B．more people will be out of jobs

C．more people will suffer from mental problems

D．more people will commit suicide

68．The United Nations agency worried that________.

A．more rich people would commit suicide

B．the financial crisis might especially influence developing or underdeveloped countries

C．the current market meltdown could worsen feelings of despair

D．hundreds of millions of people in the world were already affected by mental problems

69．It is implied that ________.

A．far more work should be done to help those who are mentally ill

B．it will be surprising to see more people commit suicide

C．a mental disorder is a chronic disease

D．many more adults commit suicide worldwide than people of other ages

70．The best title for the passage is _________.

A．Consequences of Global Financial Crisis.

B．Mental Disorders Resulting From Global Financial Crisis.

C．Suicides as a Result of Market Meltdown.

D．Chronic Mental Disorders.
