【每日訓(xùn)練】英語四級(jí)六級(jí)閱讀(09)
小編寄語：英語四級(jí)六級(jí)考試，閱讀是不可或缺的一大部分，生詞多，理解難，時(shí)間少，是不少考生抱怨的問題。要想在考場上做好閱讀理解，必須在平常多閱讀，掌握新詞匯，提高閱讀速度。而滬江小編就為大家準(zhǔn)備了閱讀材料系列，供大家練習(xí)。
我們的這個(gè)閱讀系列旨在為大家提供一些閱讀材料，不一定跟四六級(jí)考試的難度、篇幅、內(nèi)容完全一樣。對(duì)于很多童鞋糾結(jié)這是四級(jí)還是六級(jí)范圍的閱讀，其實(shí)沒有必要。如果大家覺得比較簡單，就當(dāng)作泛讀材料了解了解，認(rèn)識(shí)幾個(gè)新單詞或新表達(dá)方式也不錯(cuò)。如果大家覺得這些材料理解上有難度，不妨當(dāng)做挑戰(zhàn)自己的拔高訓(xùn)練，希望大家都有進(jìn)步^^

Wearing a light blue wetsuit that matches the colour of the sea will make you less likely to become the victim of a shark attack, according to researchers. Sharks are completely colour-blind and only see things clearly if they are mostly light or dark, scientists have claimed. In a breakthrough that could prove hugely beneficial to divers navigating shark-filled waters, scientists found that the predator - like dolphins, seals and whales - is unable to distinguish between colours. Costumes or wetsuits that camouflage swimmers' bodies in the sea water are less likely to draw a shark's attention than ones with bright, solid colours than emphasise their outline.
Professor Nathan Hart, from the University of Western Australia, said: 'It’s the high contrast against the water rather than the colour itself which is probably attractive to sharks. 'So you should wear perhaps more muted colours or colours that match the background in the water better.' The researchers examined the eyes of dead sharks and found they had only one type of photoreceptor in the retina, indicating they could only see in monochrome.
The U.S. Navy has conducted tests that suggested sharks were able to see yellow most clearly. The tests had been to see what would be the best colour for the lifejackets that pilots wear in case they have to eject and splash down in the ocean. Professor Hart said it was more the high contrast of yellow, not the colour itself, that would increase the visibility for sharks. He said: 'It may be possible to design swimming attire and surf craft that have a lower visual contrast to sharks and are therefore less attractive to them.' The study by researchers at the University of Western Australia and the University of Queensland, is to be published in the German nature journal Naturwissenschaften (Science of Nature).
【內(nèi)容簡介】
本文開篇邊介紹了鯊魚是“色盲”這一研究發(fā)現(xiàn)，接著又介紹說明海豚、鯨魚等其它海中巨獸也是色盲，由此專家提出建議穿何種顏色泳衣可避免被攻擊。
文章同時(shí)也介紹了鯊魚最能感知的是黃色這一發(fā)現(xiàn)并闡明了原因。最后文章講述了這一發(fā)現(xiàn)對(duì)海底救生船及救生衣設(shè)計(jì)的作用。
【詞匯短語講解】
①beneficial? to? 有利于，有益于
②in case? 以防，萬一，后接從句。
in case of? 若某事發(fā)生，加入，后接名詞或名詞短語。
如：In case that it rains, we should take an umbrella.
In case of rain, we should take an umbrella.
以防下雨，我們應(yīng)該帶把傘。
③draw one's attention=catch one's attention? 引起……的注意
④solid color 單色，純色??? muted color 中性色
⑤be attractive to? 對(duì)……有吸引力的
【快速閱讀支招】
這類介紹性文章不長，但經(jīng)常會(huì)有一些專業(yè)詞匯，比如這一篇就有關(guān)于海洋和光學(xué)類詞匯。我們?cè)陂喿x理解過程中要把重心放在核心句上，比如研究的結(jié)果、研究的過程及研究的意義，這類信息比較容易考到?？紙錾蠒r(shí)間較緊，對(duì)于一堆不認(rèn)識(shí)的專業(yè)詞匯過于較真可能會(huì)浪費(fèi)很多時(shí)間，在不影響整體理解的前提下我們可以猜詞語意思，猜不出來就把握好句子主體意思。
