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(黑边鳍真鲨) 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.

查看习题详情和答案>>Nick Campbell sat at the side of the road and wondered what to do next. He looked at the second-hand Harley Davidson he’d bought from a back-street garage back home in Miami at the beginning of his trip six weeks before.
For years he had dreams of crossing the United States from east to west by motorbike and he’d finally decided that it was now or never. He’d given up his job, sold his car and set off for the journey of his dreams. He’d been lucky, or so he thought, to find this old Harley Davidson and had bought it for a very reasonable price------it had cost him just $600. But five kilometers from Atlanta, he had run out of luck. The motorbike had broken down.
He pushed the bike into town and found a garage. The young mechanic told him to leave the bike overnight and come back the next day. The following morning, to his surprise, the man asked if the bike was for sale. “Certainly not,” he replied, paid his bill and hit the road.
When he got to Kansas the old machine ran out of steam again. This time Nick thought about selling it and buying something more reliable, but decided to carry on. When the bike was going well, he loved it.
However, in Denver, Colorado the bike broke down again so he decided to take it to a garage and offer it for sale. The mechanic told him to come back in the morning.
The next day, to his amazement, the man offered him $2,000. Realizing the man must be soft in the head, but clearly not short of money, Nick asked for $ 3,000. The man agreed and they signed the papers. Then the mechanic started laughing. In fact it was several minutes before he could speak and when he could he said, “That’s the worst deal you’ll ever make, boy."
He removed the seat. On the underside was the inscription (铭文):
'To Elvis, love James Dean. '
56. Harley Davidson here refers to a _________.
A. car B. truck C. garage D. motorbike
57. Which of the following did Nick value most?

58. Nick was unwilling to sell his Harley Davidson because he thought it was
A. lovely B. valuable C. reliable D. old
59. The underlined word ~ hi the 6th paragraph is closest in meaning to
A. clever B. crazy C. honest D. kind
60. At the end of the story, Nick must have felt very __________.
A. sorry B. delighted C. excited D. moved
