Most sharks are dangerous. The largest kind of sharks—the whale shark—has small teeth and is quite harmless to people. However, blue sharks, tiger sharks, white sharks and hammerheads are enemies of man.
Man-eaters are always a danger to swimmers in shark waters. Sometimes, though, men have used strange methods when they’re suddenly faced with a shark.
During world War Ⅱ, soldiers and sailors whose boats or planes were destroyed drifted(漂流) helplessly on the ocean in small rafts(筏子). While waiting to be saved, the men had to struggle to stay alive and were often attacked by sharks. In some cases, they had few weapons to protect themselves with. They found that just splashing(溅水) water seemed to help keep the sharks away.
One sailor was swimming for his life in the Atlantic Ocean after his boat had been blown up. He saw a shark swimming towards him. He hit the shark with his bare fist, and that drove it off.
Once, in Australia, a fisherman was fishing after sunset. He hooked a big fish and drew it towards the shore. His line broke when the fish was only a few yards from the shore. The fisherman waded(涉水) into the water to try to catch it with his hands. In the dim light, it looked like the kind of fish that could be dealt with without danger.
He put his arms around the fish and wrestled with it. Dragging it to the beach turned out to be harder than he had expected, but at last he pulled it in. When he turned a light on it, he was amazed. He had caught a shark. It was small for a shark, but it was the man-eating type and was about as long as a tall man.In a word, the best way to deal with sharks is to keep far away from them.
60. The shark that is least dangerous to man is the ________.
A. white shark      B. whale shark   C. tiger shark     D. hammerhead shark
61. This story tells you that sharks are usually ________.
A. friendly         B. small         C. afraid of people     D. dangerous
62. After the Australian fisherman found he had caught a shark, he was _________.
A. surprised      B. frightened      C. unhappy      D. angry
63. This story tells you that the best way to handle sharks is to ________.
A. hit them with your fist                 B. keep far away from them
C. splash water                         D. wrestle with them
64. The passage mainly tells us something  ________.
A. about fishing sharks                  B. about sharks
C. how to eat  sharks                   D. that sharks are man’s enemies

It is well known that the Japanese people’s love of fish is almost as a bee’s interest in honey.As fish populations were decreasing, fishing companies were forced to fish further and further away from the shore.Then they had a big challenge-how to keep the fish fresh for longer.So they decided to keep the fish stored in freezers on the boats.But the public did not like frozen fish.So again the fishing companies had a new bigger challenge.What they decided to do was to have fish tanks on their boats.After catching fishes, they would put them in the tanks and keep them living there until they got back to shore.But in this protected environment, lacking predators (掠食者),the fish stopped moving around.The Japanese public felt these dull fish did not taste fresh, which had an unpleasant effect upon sales.Once again the fishing companies had an even bigger challenge

Stop for a minute! Before we go any further, I would like to ask “What are your challenges? How do you handle an unexpected challenge?” May I think it this way that you should try to attack your challenges? Conquer(战胜) them with a Swiss army knife.Take the most proper and simple tool that you can adopt to deal with your situation.

Now back to our story.How did the Japanese finally figure out the fresh fish problem?Sharks! You might think the same.Sharks were caught and put into the tanks with other fishes.Don’t sharks eat fish? Well, they do eat a few fish, but they did also keep more fish active and alert (警觉的).The fish stay fresh because they are challenged.

Now, try to keep yourself fresh by finding your own shark to offer yourself a challenge in your own business and career.

The main reason for the fishing company to fish in the far sea was that         .

       A.the fish resource near the shore was on the decrease

      B.the fishes farther away from the sea tasted fresher       

       C.people would prefer eating fresh fishes to less fresh ones

       D.it was getting harder and harder to keep fishes fresh

From the text we can learn that           .

       A.Japanese people love honey as much as a bee does

       B.the fish kept in tanks didn’t sell well because of their taste

       C.the fish stored in the protected environment tasted the best

       D.the fish kept in tanks didn’t taste fresh because they died before reaching the restaurant

The underlined part of the last paragraph means “            .”

       A.If you went fishing, you might do as the fishing companies did

       B.Try to find a big shark, and you will meet your challenge

      C.To succeed in life, you should always be ready to meet challenges

       D.Sharks are usually compared to the challenges in people’s life

The purpose for the author to write the passage is to        .

       A.tell the readers “no pains, no gains”

       B.tell the readers how the Japanese keep the fish fresh

       C.advise readers to look for challenges to make progress

       D.advise readers to find something difficult to do

Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鲨鱼).

Research by a British biology student suggests that sharks could be used to predict storms.

Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure.

If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.

Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.

She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.

Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.

Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”

“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”

It has been discovered that a shark senses pressure using hair cells in its balance system.

At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.

In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模拟) oceanic pressure changes caused by weather fronts.

She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

For photographers lacking training, experience and even the ability to click a shutter button, they produce remarkable pictures.Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned creatures are opening up vistas(远景)by taking cameras where no human can go.

This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all.

Since its debut(首次公开露面)in 1987 on the back of a turtle, the Crittercam and similar devices developed by others have grown smaller and more powerful.

“It’s more than just a camera now,” said Greg Marshall, the marine biologist and now filmmaker who invented the Crittercam.“We are now including more instruments to gather more data while at the same time reducing everything in size.”

The idea of attaching video cameras to animals came to Mr.Marshall in 1986 on a dive off Belize when a shark apporached him.When the animal quickly turned away, he noticed a shark with a sucker fish on its belly.He came up with the idea that putting a camera in place of the sucker fish would allow people to witness the shark’s behavior without disturbing it.

Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land animals.

Birds are a new addition, Mr.Marshall said.Dr.Christian Rutz of Oxford recently reported on tiny cameras called feathercams that monitor the crows in the South Pacific.It has discovered that crows are smarter than anyone knew they not only use twigs(嫩枝)and grass stems as tools to root out food, but they also save their favorite tools to use again.

Tracey L.Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam was a powerful tool in her work with leopard seals(豹斑海豹)in Antarctica.“In studying animals,” Dr.Rogers said at the meeting, “you want to see how our animal models align(与……一致)with reality.With a camera, you actually see what they do.You don’t have to guess.”

What’s the text mainly about?

A.The advantages of crittercam.

B.The development of Crittercams in the past 20 years.

C.How crittercam was invented.

D.How crittercam works.

What inspired Marshall to invent crittercam?

A.The sight of sucker fish clinging to a shark on a dive.

B.The thought of how to photograph animals better.

C.Noticing a shark eating a sucker fish on a dive.

D.Seeing a shark with a camera on its belly on a dive.

According to Dr.Rogers, crittercam ____.

A.can clear up all your doubts about animals

B.is the most powerful tool in studying animals

C.enabled her to observe the crows in the South Pacific closely

D.helped a lot with her research on leopard seals in Antarctica

All of the following are improvements of crittercams EXCEPT that ____.

A.the size is becoming smaller

B.more instruments are involved to gather more data

C.they allow researchers to see where and how animals live

D.they are able to be applied to smaller animals such as birds
