Question

3．Michael Fish may soon be replaced as a weather forecaster by the shark （鯊魚）．
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 behavior 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．
72．The passage is most probably taken fromB．
A．a(chǎn) short-story collection
B．a(chǎn) popular science magazine
C．a(chǎn) research paper
D．a(chǎn) personal diary
73．What do we learn from the first four paragraphs of the passage？A
A．Sharks may be used to predict bad weather．
B．Sharks'behavior can be controlled．
C．Michael Fish is not fit for his job．
D．Lauren Smith will become a weather forecaster．
74．Lauren Smith conducted her research byD．
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
75．What is the passage mainly about？B
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

分析 本文為科普類文章，介紹了一位英國生物系學生對于鯊魚來預(yù)測暴風雨的研究，Miss Smith 通過在鯊魚身上安裝高科技感應(yīng)器來記錄壓力和溫度，研究暴風雨的預(yù)測．

解答 72．B．推理判斷題．本題適宜用排除法．由文章內(nèi)容來看這是一篇科普文，A、D可刪除，由文章的語言來看，并未出現(xiàn)大量的專業(yè)術(shù)語，可刪除C"a research paper"（科研論文）； 故選B
73．A．推理判斷題．根據(jù)文章第四段If her studies prove the theory，scientists may be able to monitor the behavior of Sharks to predict bad weather．（科學家們可以通過監(jiān)視鯊魚的行為來預(yù)測不好的天氣"．故選A．
74．D．事實細節(jié)題．由文章倒數(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，Miss Smith 在鯊魚身上安裝高科技感應(yīng)器來記錄pressure（壓力）和temperature（溫度），故選D．
75．B．主旨大意題．文章的主旨句為第二段"Research by a British biology student suggests that sharks could be used to predict storms"全文圍繞著鯊魚可能被用來預(yù)測天氣的研究展開．因此文章主要關(guān)于一項預(yù)測暴風雨的研究；故選B．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
