【题目】Michael Fish may soon be replaced as a weather forecaster by something truly fishier — shark.
Research by a Britain 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 behavior of lemon sharks.
She then used their close relatives, lesser spotted dogfish, for further research.
Her work—thought to be the first of its kind to test pressure theory—resulted from observation that juvenile sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said, “I’ve always been crazy about travelling and diving and this led me to an interest in sharks.”
“I was delighted to gave been able to reach 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 balanced system.
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 short-story collection
A popular science magazine
A research paper
A personal diary
【2】What do we learn from the first four paragraphs of the passage?
Sharks may be used to predict bad weather
Shark’s behavior can be controlled
Michael Fish is not qualified for his job
Lauren Smith will become a weather forecaster
【3】Lauren Smith conducted her research by ______.
Removing hair cells from a shark’s balance system
Measuring the air pressure of weather fronts
Recording shark’s body temperature
Monitoring shark’s reaction to weather changes
【4】What is the passage mainly about?
A popular way of forecasting weather
A new research effort in predicting storms
Biologist’ interest in the secrets of sharks.
Lauren Smith’s devotion to scientific research
【答案】【1】B
【2】A
【3】D
【4】B
【解析】【1】推理判断题。本题适宜用排除法。文章内容可是是一篇科普文，而又没有大量的专业术语，故应当选择B。
【2】推理判断题。前四段表达的要意思是“科学家们可以通过鲨鱼的特性来预测不好的天气”。
【3】事实细节题。由文章倒数第三段可知是在鲨鱼身上安装高科技感应器来几率pressure和temperature。
【4】主旨大意题。文章的主旨句为第二段，全文围绕着鲨鱼可能用来预测天气展开。
