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 behavior 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.
1.The passage is most probably taken from _____.
A.a short-story collection | B.a popular science magazine |
C.a research paper | D.a personal diary |
2.What do we learn from the first four paragraph of the passage?
A.Sharks may be used to predict bad weather . |
B.Sharks’ behaviour can be controlled. |
C.Michael Fish is not qualified for his job. |
D.Lauren Smith will become a weather forecaster. |
3. Lauren Smith conducted her research by _______.
A.removing hair cells from a shark’s balance system |
B.measuring the air pressure of weather fronts |
C.recording sharks’ body temperature |
D.monitoring sharks’ reaction to weather changes |
4.What is the passage mainly about?

A new United Nations report shows that fish farming may soon be the world’s most important provider of fish. The Food and Agriculture Organization says fish farming is growing at a rate of 6.6 percent a year.
Fish farming now produces forty-six percent of the world’s supply of fish. That represents a forty-three percent increase from 2006. The report also said fish farming earned more money in 2008 than traditional fisheries.
In fish farming, fish are raised in tanks or small bodies of water called ponds. They are also raised in cages or nets in oceans, lakes and rivers. The report says increased fish farming has helped people around the world eat record amounts of fish. The FAO says each person ate an average of almost seventeen kilograms of fish last year.
However, the FAO says the current yearly wild-fish harvest of ninety million tons shows no improvement. Decreasing numbers of fish and stronger catch limits have reduced the possibilities for catching wild fish. The FAO report says about thirty-two percent of world supplies are overfished. It says these supplies of fish need to be rebuilt at once.
Some scientists have criticized fish farming. They say the nets and cages permit fish diseases and pests to spread. Some fish farming critics doubt whether fish farming can keep growing at the current rate. But Wally Stevens of the trade group Global Aquaculture Alliance says the industry must continue developing to feed growing populations. Mr. Stevens says a one hundred percent increase in fish farming over ten years is necessary to keep providing for people at the current level. He notes that fish farming creates jobs and wealth, especially for people in coastal areas of China.
1.We learn that since the year 2006, fish farming has been ______.
A.earning more money than traditional fisheries
B.developing rapidly around the world
C.growing at a rate of 6.6 percent each day
D.producing 46% of the world’s supply of fish
2.According to Paragraph 3, thanks to fish farming, people around the world are able to ______.
A.buy more kinds of fishes B.eat more fish than before
C.eat much healthier fish D.eat much bigger fish
3.What is implied in Paragraph 4?
A.it is harder to catch wild fish than before.
B.It costs too much to rebuild supplies of fish.
C.There is no future for the market of wild fish.
D.Catching wild fish no longer brings benefits.
4.What does Wally Stevens think of fish farming?
A.It doesn’t have disadvantages at all.
B.It cannot keep growing at the current rate.
C.It is not a good way of raising fish.
D.It must develop fast to supply a growing population.
