On April 24^th, another natural disaster—the oil spill(泄露) in the Gulf of Mexico, happened. Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．

But governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run.

Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．

However, we should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太阳能）, electricity, hydrogen, and so on．Much of this research, in the past, was stopped by the oil, gas, and coal．

If the world’s millions of cars were 10% more efficient（高效的）,we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．

1.What is the passage mainly talking about?

2.How does the author support the idea that oil spills are not as serious as people believe?

3.What does the underlined word "risk" in Paragraph 2 refer to?

4.Which suggestion is made for reducing oil tank accidents according to the passage?

5.Where can you read this article?

I suppose that having been brought up in the countryside and close  to animals，it wasn’t remarkable(不平常的)when I decided  to become a vet(兽医)．Luckily I was also good at all the necessary science subjects. So after the college entrance examination I found myself at a veterinary college，training to look after animals in all kinds of situations. I hoped that I would be able to work in the research field so that I could find cures for animal diseases.

Much to my surprise，I found public health care was a very important aspect of my course. This is an area of animal medicine where a vet’s work has many things in common with the work of a doctor of human diseases. I particularly liked it because I recognized that the study of animal diseases can help human medicine. As we know，many infectious diseases come from animals—including SARS and bird flu.

Some of the infections have only been understood after carefully analytical work in labs by animal doctors. They helped identify the animal source for diseases such as SARS. They were also the first to identify various kinds of viruses. Sometimes vets are also able to suggest a cure for human illnesses. When I found this out I was determined to make public health medicine my chosen career.

After graduation，I applied for a job in public health. Soon I found myself concerned with the problem of bird flu. This is  an illness that attacks birds，but humans can catch the disease  if they are in close contact with infected birds. Though the job  is dangerous，it makes me proud that vets and other animal  disease researchers are in the front line helping to fight these  unknown human diseases

While the presence of rats in homes may cause anxiety and annoyance，they rarely result in driving out the residents.But that is exactly what happened to the inhabitants of the 10-square-mile Hawadax Island off the coast of Alaska，almost 230 years ago.Now thanks to a five-year effort by scientists，the terribly silent “Rat Island” as it had been called for many years has been returned to its rightful owners—birds!

Hawadax Island is part of a chain of volcanic islands in the Bering Sea called the Aleutian Islands.The rats that arrived there in 1780，when a Japanese ship carrying them broke down nearby，completely destroyed the native population because the environment of the island was not built to defend its animals from these predators.There isn't any tree on the island，which meant that the birds were accustomed to building their nests low in the ground，giving the rodents(啮齿动物) easy access to both eggs and baby chicks.As years passed，the birds that had called the island home for thousands of years became endangered and eventually，disappeared completely.

In 2007，the US FWS(Fish and Wildlife Service) started a serious plan to rid the island of the rats and try bringing back the beautiful birds that had once called it home.Given that there were an estimated 10，000 rodents inhabiting “Rat Island” and the fact that they reproduce rapidly，it was not an easy task.But by 2009，the island was officially declared rat free!

Then slowly but surely，the birds began to return. Unfortunately，some of the pioneers were unintentionally killed from the leavings of the raticide，a poison that had been used to wipe out the rodents.But now it seems things are becoming more stable and the island is starting to increasingly look like its former self.Before the transformation，“Hawadax”，also known as “Rat Island”，was a silent and ghostly place with bird bones，snail remains and rocks covered in rat feces(粪便)．

Today，birds' singing and flying in and out is a common sight.Tufted puffins and song sparrows，which had long disappeared，are gradually making their way back.Scientists have also been observing an increase in ground nesting and shore birds.Though the island is still not back to its full glory，the signs are encouraging and things can only get better，as time passes.

1.The underlined word “that” in Paragraph 1 probably refers to ________.

A．birds' being driven out

B．the presence of rats

C．birds' returning to the island

D．residents' worrying about rats

2.Birds on Hawadax Island became an easy target because ________.

A．their chicks were extremely weak

B．they nested randomly

C．they reproduced too rapidly

D．this island was treeless

3.From the passage，we can know the plan of US FWS ________.

A．has helped the island fully recovered

B．cost little but benefited greatly

C．involved poisoning the rats on a large scale

D．accomplished its goal after exactly 24 months

4.Which would be the best title for the passage?

A．FWS help get rare birds back to alaska island

B．Japanese changed a bird paradise into rat island

C．Alaska's rat island returns to a bird paradise

D．FWS plan to drive rats out of rat Island
