“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(超过) 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(碳酸钙) 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.”

Climbing Mount Kilimanjaro, the highest mountain in Africa, is an impressive deed for anyone, but especially for one man who reached the 19,340-foot peak without the use of his legs.
Chris Waddell, 43, broke his back in a skiing accident while at college in Vermont in 1988. The athlete was left paralysed from the waist down, but never gave up sports. During one sports meeting for the disabled, Waddell was the top male skier, winning 12 medals in four events. Not content with this achievement, Waddell decided to climb the highest mountain in Africa with his arms.
The adventurer began the climb with seven teammates and 60 porters, who provided support and placed boards across gaps. Despite the difficulties, the group completed the 30-mile hike from rainforest to glacier in an impressive six and a half days ---- just a couple of days longer than most able-bodied hikers.
He certainly inspired a student, Brandon Gell, after speaking at Horace Greeley High School in New York. Gell said,“I began thinking of the difficulties in my life, and they seemed unimportant. Waddell’s determination and struggles inspire me to push my own limits.”
Waddell says,“A revolution begins with something small and leads to something big ---- one turn of the crank(曲轴) can lead to peak of Mt. Kilimanjaro, and one word to a child can change the nature of that child’s perceptions(洞察力).”The underlined words, “was left paralysed”, in the second paragraph means ________.
| A．was given scars |
| B．became hurt deeply |
| C．was not able to bend |
| D．became unable to move |
Which of the following about Chris Waddell in NOT true?
| A．He never gave up as an athlete. |

The Frog and The Crane
In the heart of the woods there lay a cool, green pond. The shores of the pond were set with ranks of tall bulrushes(芦苇) that waved crisply in the wind, and in the shallow bays there were fleets of broad water lily leaves. Among the rushes and reeds and in the quiet water there dwelt a large tribe of Frogs.
On every warm night of spring, the voices of the Frogs arose in a cheerful chorus. Some voices were low and deep---these were the oldest and wisest of the Frogs; at least, they were old enough to have learned wisdom. Some were high and shrill, and these were the voices of the little Frogs who did not like to be reminded of the days when they had tails and no legs.
"Kerrump! kerrump! I'm chief of this pond!" croaked（哇哇叫） a very large frog, sitting in the shade of a water lily leaf.
"Kerrump! kerrump! I'm chief of this pond!" replied another voice from the opposite bank.
"Kerrump! kerrump! I'm chief of this pond!" boasted a third old Frog from the furthest shore of the pond.
Now a long-legged white Crane was standing near by, well hidden by the coarse grass that grew at the water's edge. He was very hungry that evening, and when he heard the deep voice of the first frog ,he made a quick pass under the broad leaf with his long, cruel bill. The old Frog gave a frightened croak, and kicked violently in his efforts to get away.
The Crane almost had him, when something cold and slimy wound itself about one of his legs. He drew back for a second, and the Frog got safely away! But the Crane did not lose his dinner after all, for about his leg was curled a large black water snake, and that made a fair meal.
Now he rested awhile on one leg, and listened. The first Frog was silent, but from the opposite bank the second Frog croaked boastfully:"Kerrump! kerrump! I'm chief of this pond!"
The Crane began to be hungry again. He went round the pond , trying to catch the second frog..
Just as he drew closer to the frog, the Crane saw something that made him let go. a mink(水貂) had crept very close to the Crane, hoping to seize him at his meal! So the second Frog got away too; but he was so dreadfully frightened that he never spoke again.
After a long time the Crane got over his fright and he became very hungry once more. The pond had been still so long that many of the Frogs were singing their pleasant chorus, and above them all there boomed the deep voice of the third and last Bullfrog, saying: "Kerrump! kerrump! I'm chief of this pond!"
The Crane determined to silence him once for all. He croaked and struggled in vain. But just then a Fox crept up behind the Crane and seized him! The Crane let go the Frog and was carried off screaming into the woods for the Fox's supper. So the third Frog got away; but he was badly lamed by the Crane's strong bill, and he never dared to open his mouth againWhy didn’t the crane catch the first frog?
| A．Because the frog kicked too violently. |
| B．Because something would itself around the crane’s leg. |
| C．Because the crane was distracted by another frog. |
| D．Because the frog was frightened away by the noise of the crane. |
According to the passage, the crane ______.
| A．ate nothing that night |
| B．got hurt three times |
| C．let all the three frogs get away |
| D．didn’t dare to catch the frogs in the end |

| A．It is dangerous living in the woods. |
| B．A wise person always keeps silent. |
| C．Be careful when you are close to your goal. |
| D．Never be proud, even if you have done well. |

| A．In a children’s book |
| B．In an introduction to animals |
| C．In a book about dangers in the woods |
| D．In a book full of information about ponds. |

The new species of monkey was officially unveiled in a scientific journal last week.
The animal kingdom has a new member. On September 12, researchers unveiled（揭开）to the world a newly discovered species of monkey. The primate(灵长类动物) is called the lesula, short for its Latin name, Cercopithecus lomamiensis. The lesula is only the second monkey species discovered in 28 years.
Meet the Lesula
Scientists first saw the lesula in June 2007 in the town of Opala in the Democratic Republic of Congo. The Democratic Republic of Congo, often called the DRC, is located in Central Africa. The lesula lives in the lowland rainforests of central DRC. The monkey found in Opala was the pet of a local family. Researchers say the species was already well known to hunters. The found additional lesulas in the wild.
The lesula has been compared to another species of monkey calledCercopithecus hamlyni, better known as the owl-faced monkey. This animal earns its name for having a long, flat nose and a face that that looks like that of an owl. The lesula and the owl-faced monkey are similar in size and both have a stripe on their nose. These new findings on the lesula prove that the two monkeys are close relatives, but different species. Scientists say the lesula usually weighs about 12 pounds and measures about 20 inches. It has a mane of long blond hair and a cream-colored stripe running down its nose. The lesula eats a vegetarian diet. Its habitat extends nearly 11,000 square miles across the DRC’s eastern central basin.
Robert Kityo is a zoology professor at Uganda’s Makerere University. He says that the lesula discovery is proof that the eastern central basin is filled with species yet to be discovered. This new find also creates awareness about the importance of preserving, or protecting, African rainforests. Many forests are threatened by illegal logging and hunting. Preserving these rainforests allows new species like the lesula to continue to grow and change.The monkey found in Opala __________.
| A．was the only living lesula |
| B．got lost from its group |
| C．was raised by a local family |
| D．was unknown to the hunters |
Why was the Cercopithecus hamlyni called the owl-faced monkey?
| A．It has the same color as owl. |
| B．Its face looks like that of an owl. |
| C．It eats the same diet as owls. |
| D．It has the same strip on its nose as owls. |
What has been found about the lesula and the owl-faced monkey?
| A．They were found in the same area. |
| B．They belong to the same species. |
| C．They are close relatives. |
| D．Both of them eat a vegetarian diet. |
The lesula discovery indicates that _______.
| A．many species remain to be discovered in eastern central basin |
| B．illegal logging and hunting are the main threats to African rainforests |
| C．effective measures should be taken to control the exploration of the African rainforests |
| D．African rainforests are disappearing gradually because of lack of protection |
