Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmosphere 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 atmosphere CO2 into the ocean.”

Scientists expected that as atmosphere 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 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 samples Dore and his colleagues have analyzed confirm 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.”

The increase in tuition fees(学费) has led to a “clear drop” in the number of English students applying for university places this autumn. There are 15,000 “missing” applicants this academic year, according to the Independent Commission on Fees. Chairman Will Hutton said: “We’re asking our young men and women to have more debt than any other country in the world — it’s higher than the average debt in the US. It’s not clear whether those lost students this year will return next year, or if it’s a storm warming of a worrying trend.”

But the commission’s report says there does not seem to be an impact on poorer communities. The commission found there was no significant change in the application rate to the key universities, such as Oxford or Cambridge. The decline （下降）in England has not been mirrored in other parts of the UK where fees have not been raised, and the drop can only partly be explained by falling numbers of young people in the population. Students from Scotland attending Scottish universities do not pay fees, while the Welsh Assembly says it will pay fees above ￡3,465 for Welsh students attending UK institutions.

The average tuition fee at English universities this year is ￡ 8,385, rising to ￡ 8,507 next year. UK and EU students have access to govemment-backed loans to pay the fees. And the survey of 1,000 pupils aged 15-18, carried out this April, found that the majority expected to go on to higher education as people continue to understand that university remains a good long term investment in their future.

A spokeswoman at the Department for Business, Innovation and Skills which is responsible for universities, said:“Students shouldn’t be forced to put off going to university for financial reasons. Most students will not have to pay in advance, and no one will have to start paying back their student loan until they start to earn at least ￡ 2l,000 per year.”

1.From the first paragraph, we know that __________________ .

A. it’s a trend that English students are dropping out of school

B. the rising tuition fees have a great effect on English students

C. the lost English students will find their way back

D. many English students are missing the final examinations

2.Why is there still a drop of applicants though fees have not been raised?

A. Because the students live in poor communities.

B. Because Welsh students will pay fees above￡3,465.

C. Because education is free for Scottish students.

D. Because there are less young students in the area.

3.What’s the students’ attitude to universities in the survey?

A. Most of them are willing to go to university.

B. They feel universities takes up too much time.

C. They will stop applying for university places this autumn.

D. They are anxious to go to a key university.

4.The spokeswoman in the last paragraph advises students to ______________

A. put off going to university

B. reduce the anxiety about the rising fees

C. pay for the fees in advance

D. pay back their loan soon after graduation

There are some things humans can go without. We can lose a kidney (肾)or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.

One such fish is the stout longtom（尖嘴魚 ）. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.

The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical(热带) fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. Its teeth are not good at cutting fish into pieces, so it swallows fish whole.

Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.

Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin（胰岛素） that can break down proteins without acid — although the approach is less efficient than using a stomach.

Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.

Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.

1.What does the underlined phrase “get by” mean?

A. Live.B. Fight.C. Hunt.D. Recover.

2.Ryan Day ran the chemical tests in order to find out how the longtom ______.

A. catches smaller fish in the water

B. can jump so high to escape its enemies

C. digests the smaller fish in its body

D. uses acid to break down the protein

3.What plays a key role in the longtom’s digestion process?

A. AcidB. Trypsin.C. The stomach.D. Protein in its body.

4.Ryan Day’s results show that ______.

A. the longtom often waste energy

B. the longtom can make acid easily

C. the longtom’s high-protein food helps its unique way of consuming food.

D. meat-eating fish have higher levels of trypsin in their bodies than plant-eating fish
