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 _____.

2.What do we learn from the first four paragraph of the passage?

3. Lauren Smith conducted her research by _______.

4.What is the passage mainly about?

A small piece of fish each day may keep the heart doctor away. That's the finding of an extensive study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed(消费) at least an ounce of salt water fish per day than those who never ate fish.

The Dutch research is one of three human studies that give strong scientific backing to the long-held belief that eating fish can provide health benefits, particularly to the heart.

Heart disease is the number-one killer in the United States , with more than 550, 000 deaths occurring from heart attacks each year . But researchers previously have noticed that the incidence (发生率)of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age , high blood pressure , or blood cholesterol (胆固醇) levels .

1.Which of the following is NOT true according to the passage?

A. The Dutch research has proved that eating fish can help to prevent heart disease.

B. There is a low incidence of heart disease in countries like Japan and Greenland.

C. Among all the diseases heart disease is the most dangerous in America.

D. Heart doctors won’t call your house so long as you keep eating fish each day.

2.The underlined phrase “this relationship” refers to the connection between _______ and the incidence of heart disease.

A. the amount of fish eaten        B. regular fish-eating

C. the kind of fish eaten      D. people of different regions

3.The passage is mainly about __________________.

A. the high incidence of heart disease in some countries

B. the changes in people’s diet in the United States

C. the daily fish consumption of people in different cultures

D. the effect of fish eating regularly on people’s health

4.How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?

A. 550, 000.        B. 110,000.     C. 275,000.         D. 852.

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.
