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.

While it is impossible to live completely free of stress，it is possible to prevent stress as well as reduce its effect when it can’t be avoided．The US Department of Health and Human Services offers the following suggestions for ways to deal with stress．
◆Try physical activity
When you are nervous, angry or upset, try releasing the pressure through exercise or physical activity. Running，walking，playing tennis，and working in your garden are just some of the activities you might try.
◆Take care of yourself
You should make every effort to eat well and get enough rest. If you easily get angry and can’t sleep well enough, or if you’re not eating properly, it will be more likely that you will fall into stressful situations．If stress repeatedly keeps you from sleeping，you should consult a doctor．
◆Make time for yourself
Schedule time for both work and entertainment．Don't forget，play can be just as important to your overall well-being as work. You need a break from your daily routine to just relax and have fun．Go window-shopping or work on a hobby．Allow yourself at least a half hour each day to do something you enjoy．
◆Make a list of things to do
Stress can result from disorganization and a feeling that “there’s so much to do，and not enough time”．Trying to take care of everything at once can be too much for you and as a result，you may not achieve anything．Instead，make a list of everything you have to do，then do one thing at a time，checking off each task as it is completed．Set out to do the most important task first．
【小题1】Which of the following statements shows that you have fallen into stressful situations？
| A．You can't sleep well all the time． |
| B．You have a break after work． |
| C．You always feel happy and relaxed． |
| D．You only do one thing at a time． |
| A．Try to take care of everything at once． |
| B．Do one thing at a time． |
| C．Only do the most important thing． |
| D．Have a break from your work． |
| A．How to Deal with Stress? |
