Dolphins and sharks are showing up in surprisingly shallow

water just off the Florida coast. Mullets, crabs, rays and small

fish gather by the thousands off an Alabama pirer. Birds covered in

oil are crawling deep into marshes （沼澤）, never to be seen again.

Marine scientists studying the effects of the BP disaster（英國石油公司漏油事件）are seeing

some strange phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign. The animals' presence close to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run out of oxygen. Also, the animals could easily be captured by their enemies.

    The nearly two-month-old spill（漏油）has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try to understand the effects on thousands of species of marine life.

For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate

islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking（嬉戲）in the oily sheen（光澤）and oil-tinged pelicans feeding their young. But they spotted no dead animals.

"I think part of the reason why we're not seeing more yet is that the impacts of this crisis are

really just beginning," Greenpeace marine biologist John Hocevar said.

The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will

help determine how much BP pays in damages.

What do the marine life react to the BP disaster?

       A．Birds crawl deep into caves.

       B．Dolphins and sharks show up in deep water.

       C．Tens of thousands of marine animals are found dead.

       D．Sea creatures flee from oil spill, gathering near seashore.

Which of the following is NOT related to the potentially troubling sign?

       A．The usual habitat of deep-water animals is badly polluted.

       B．Many animals could be easily eaten by their enemies.

       C．Masses of fishes could die due to lack of oxygen.

       D．Some dolphins are frolicking in marshes.

The environmental disaster was caused by     .

      A．the damage of the Mexico Gulf ecosystem

       B．the lack of environmental sense of BP

       C．the nearly two-month-old oil spill

       D．the crowding marine life

What is John Hocevar’s attitude towards the disaster?

       A．Worried.   B．Disappointed.   C．Depressed.       D．Hesitant. 

From the passage, we can infer that         .

       A．Bp will pay much money according to the number of dead wildlife there

       B．marine scientists have seen some strange phenomena

       C．the disaster has little influence on dolphins

       D．a(chǎn) three-person crew reached no conclusion

　Life on land probably began about 430 million years ago, though it has existed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since they, the plants, are the only form of life that is able to get and store energy.

　　The first plants to exist out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（進化）took place quickly. By the end of 100 million years, plants had developed their roots（根）,and some had got tree-like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

The main idea of the first paragraph is ________.

　　A. life on land probably began 430 years ago

　　B. the first animal on land came from oceans

　　C. there wouldn't be animals without plants

　　D. plants are the only form of life that is able to get and store energy

Which of the following statements is true according to the passage?

　　A. Algae has existed for more than 430 million years.

　　B. It is impossible that algae might be the earliest plant on land.

　　C. Plants get food from animals in the oceans.

　　D. Evolution began after animals appeared on land.

Plants with roots appeared about ________ million years ago.

　　A. 430　　　　　B. 300　　　　　 C. 330　　　　　 D. 100

According to the passage, ________ appeared earlier than ________.

　　A. apples; oranges　　　　　　　　 B. oranges; apples

C. oranges; roses　　　　　　　　　D. algae; wheat

The devastation of Typhoon Morakot over Taiwan and eastern China is a reminder that the northwest Pacific is the most dangerous region in the world for tropical storms．The worst of these are typhoons, which are the same as hurricanes in the Atlantic and eastern Pacific, or cyclones in the Indian Ocean and Australia．They all have winds of more than 118km/h (73mph) spinning around a central core．

These storms start off as a mass of thunderstorms in the tropics outside the Equator．Given the right conditions, they form a bigger and more organised storm and feed off warm seas at more than 26．5C (80F) to get the fuel that they need to become a fully-fledged(羽毛豐滿的) typhoon, hurricane or cyclone．Each storm is like a heat engine, extracting heat from the warm, humid air over the sea and turning it into phenomenal amounts of energy — equivalent to about 200 times the entire world’s electrical generating capacity．But warm, moist air is not enough — these storms also need slack winds aloft, because strong high-altitude winds can rip off the top of the storm clouds and send the entire storm tumbling（翻跟頭）．

The damage from tropical storms often comes from their winds, or the storm surges from the sea as the winds pile up water into a huge battering ram(沖擊夯) that floods coastlines．But the devastation from Typhoon Morakot came from its unbelievable rainfall — about a year’s average rain in some places — that set off landslides and mudslides．

45．According to the first paragraph, the common point among typhoons,hurricanes and cyclones is _______．

     A．that they all come from the oceans

       B．that they all have winds of over 118km/h spinning around a central core

       C．that they all cause great damage

       D．that they all can generate electricity

46．Which of the following is the best title of this passage?

     A．Typhoon Morakat devestates Taiwan and eastern China

     B．How is the typhoon formed?

     C．Typhoon Morakot was how to devestate the areas it travelled

     D．How terrible is Typhoon Morakat!

47．The devastation from Typhoon Morakot is mainly from ______．

     A．its wind                   B．its rainfall      

       C．landslides and mudslides       D．the storm

48．It can be inferred from the passage that ______．

     A．Taiwan is off the northwest Pacific

     B．the damage from tropical storms often comes from their winds

     C．tropical storms often happen

     D．tropical storms only need warm, moist air

Somali pirates(海盜) robbed three Thai fishing ships with 77 sailors on board nearly l,200 Miles off the Somali coast，the farthest-off-shore attack to date，an officer said Tuesday.

Pirates have gone farther south and east in answer to increased patrols(巡邏) by warships off the Somali shore. The robbing of the three ships Sunday was about 600 miles outside the normal operation area for the international force，said a spokesman．

The spokesman said the attack so far out at sea was a clear sign that the international patrols against pirates were having a “marked effect on pirate activity in the area”．

“Once they start attacking that far out，you’re not even really talking about the Somali basin or areas of water that have any connection with Somalia,” said an officer，Roger Middleton．“Once you’re that far out, it's just the Indian Ocean，and it means you’re looking at trade going from the Gulf to Asia，from Asia to South Africa.”

"This is the farthest robbing to date．They are now operating near the Maldives and India,” said another officer．

The three ships--the MV Prantalay 11，12，and l 4—had 77 members on board in total．All of them are Thai, the spokesman said．Before the Sunday robbing，pirates held 11 ships and 228 sailors．

Pirates have increased attacks over the past year in hopes of catching more dollar payments. Because of increased patrols and defenses on board ships，the success rate(率)has gone down，though the number of successful attacks has stayed the same year over year.

The pirate attack reported in the text happened            ．

A．far out in the Indian Ocean

B．in the normal patrol area

C．near the Somali, coast

D．in the south of Africa

According to the text, which can best describe the situation of the pirate problems?

A．More goods on board are lost.

B．Pirate attacks happen in a larger area now.

C．The number of attacks has stayed the same these years.

D．Pirate attacks are as serious as before along the Somali coast.

Which is true about the warship patrols according to the text?

A．The patrols are of little effect.

B．The patrols are more difficult.

C．More patrols are quite necessary even in Asia.

D．The patrols only drive the pirates to other areas.

How many sailors were held by the pirates before the time of the report?

A．228.             B．77.              C．383.             D．305.
