Question

Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鯊魚(yú)).

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(模擬) 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 _____.

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. A popular way of forecasting weather.

B. A new research effort in predicting storms.

C. Biologists’ interest in the secrets of sharks.

D. Lauren Smith’s devotion to scientific research.

 

Answer 1

【答案】

 

1.B

2.A

3.D

4.B

【解析】

試題分析：本文為科普類(lèi)文章，介紹了一位英國(guó)生物系學(xué)生對(duì)于鯊魚(yú)來(lái)預(yù)測(cè)暴風(fēng)雨的研究。

1.推理判斷題。本題適宜用排除法。由文章內(nèi)容來(lái)看這是一篇科普文，A、D可刪除，由文章的語(yǔ)言來(lái)看，并未出現(xiàn)大量的專(zhuān)業(yè)術(shù)語(yǔ)，可刪除C “a research paper”(科研論文)，選B。

2.推理判斷題。由第一段和第四段可知，前四段所要表達(dá)的含義為If her studies prove the theory, scientists may be able to monitor the behavior of Sharks to predict bad weather。(科學(xué)家們可以通過(guò)監(jiān)視鯊魚(yú)的行為來(lái)預(yù)測(cè)不好的天氣”。故A 項(xiàng)正確。

3.細(xì)節(jié)題：從文章倒數(shù)第三段Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.可知Mr Smith在鯊魚(yú)身上安裝高科技感應(yīng)裝置來(lái)記錄壓力和溫度，也就是監(jiān)控鯊魚(yú)對(duì)天氣變化的反應(yīng)，所以選D

4.主旨題：文章的主旨句在第二段Research by a British biology student suggests that sharks could be used to predict storms.：全文圍繞著鯊魚(yú)可能被用來(lái)預(yù)測(cè)天氣的研究展開(kāi)，選B
