阅读理解

Jennifer Fish, a weather forecaster may soon be replaced by something truly fishier—the shark.

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

    Laura 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 (猫鲨), 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.

    There is a lot to learn about the creations of Beatrix Potter — not only is she the author and illustrator of one of the world's most famous children's books, The Tale of Peter Rabbit, but also a pioneering conservationist with the spirit of a scientist.

    "Potter grew up as the daughter of a wealthy Victorian family, but along with her brother who filled an entire floor of their large house in London with all sorts of animals," said Anne Lundin, a retired professor for the UW-Madison School of Library and Information Studies.

    "As an adult, she was a frustrated botanical illustrator and scientist. That field was not open to her because she was female," Lundin said. Potter was urged to turn the charming illustrations and stories she wrote in letters to children into books. She wrote 23 books in all — a body of work that has inspired plays, ballets, films and an astonishing amount of merchandise.

    "The Tale of Peter Rabbit is probably the most famous children's book in the world, which was published in 1902 and has really stood the test of time. It's been translated into 36 languages. The parents and grandparents will share it with the next generation," said Lundin.

    Potter also made a mark on the world through her land conservation. "In many ways, she was like Peter Rabbit, venturing into a world of adventure and risk. She withdrew from London as soon as she started making some money on her books to the Lake District and became an extremely important farmer and conservationist. She preserved and passed on 15 farms and over 4,000 acres, which were given back to the country as gifts in the 20th century," said Lundin.

    Even though she was born 150 years ago, she was amazingly modern — her embracing of the natural world, commented Jennifer Blatchley Smith, an artistic director of the show Peter Rabbit Tales to celebrate the 150th anniversary of Potter's birth.

    A recent university study found that current electric cars could be used for 87% of daily car journeys in the US. That figure could rise to 98% by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” —drivers' concerns about running out of petrol on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. In fact, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars met with doubt, and their high price drove customers away. Thanks to improvements in battery capacity(电池容量), recharging times, performance and price, the current generation of electric cars is starting to persuade critics.

    As well as progress on the road, electric vehicles are taking to the sea and sky. Electric boats are among the oldest electric vehicles, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric planes are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make electric flight a reality.

    Electric vehicles do not produce any emissions(排放物). Were the US to act on the study's findings and replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

    Sharpshooters refer to those who are skilled at firing a gun and accurately hitting what they are aiming at. However, some fish are also called amazing sharpshooters. People wonder how they hit their targets without using tools? By spitting! The fish shoot so accurately that they rarely miss their target.

    These amazing fish are archerfish (印度射水鱼).There are several different types of archerfish living in Southeast Asia. They spit at their dinner to catch it. To catch dinner, a fish first sets itself in a certain place, for example just below the surface of the water. It puts the tip of its mouth so it barely breaks through the water. Then, the fish waits for an unsuspecting insect to land on a leaf or branch hanging over the water.

    When an unsuspecting, or unknowing insect lands, the fish attacks. The fish squeezes its gill (腮)covers very rapidly, which forces water into the fish's mouth. In the roof of its mouth the fish has a groove (槽). The fish forms the small groove and its tongue into a narrow tube by pressing its tongue up against its groove. The water forced into the fish's mouth is forcefully pushed out of the fish's mouth through the tube. Archerfish have been known to send a stream up to 5 meters (16 feet). However, archerfish can only shoot insects up to 1-2 meters (3-6 feet) away due to their limited accuracy.

    When the unsuspecting insect is hit with a sudden stream of water, it is knocked into or falls into the water. Once in the water, the insect becomes dinner. Archerfish learn how to spit when they are young. They get more accurate with practice. Adult archerfish rarely miss.

    Within a meter, archerfish will often spring out of the water and grab an insect in their mouths.

    Going back to school can be an anxious time for many students. But one institution in Texas is doing its part to make sure middle schoolers are returning refreshed and inspired to learn.

    Through a process called the "bathroom inspiration project," teachers and administrators at Warren Middle School, spent their summer beautifying the school's restrooms by painting motivational murals (壁画) on each of the stalls (小隔间).Forming messages like "Your mistakes don't define you" and "Scatter (撒播) kindness," the brightly colored words are exactly what a young student needs to see when having a rough day-or any school day for that matter. And now that classes are officially in session, people are already noticing a positive impact.

    Since posting photos of upgrades to the school in July, Principal Joshua Garcia says that the alterations have aroused a great response.

    "Students have been talking about the murals from the moment the pictures had been posted. Some even took the time to find a reason to come up to the campus to see the murals," he says." I think what makes this small little action so valuable is that it has set the tone for our campus."

    And not only is that important to students, parents, and fellow staff, but it is also vital for the school's new principal, who is trying to gain the trust of the community during a time in which trust is so necessary for schools.

    "Being new to the campus, I think the parents were able to see how much I value their children and have their best interest at heart," Garcia continues. "I have had many parents tell me how they can just feel a difference in the campus climate and how much they are enjoying seeing their children wanting to come here. These murals have put trust back in the campus and its teachers, and by doing so we are able to build a culture in which our students want to be here and learn."
