Sharks are completely colour blind and only see things clearly if they are mostly light or dark, so wearing a light blue wet-suit that matches the colour of the sea will make you less likely to become the【C1】______of a shark attack, scientists have claimed.
In a breakthrough that could prove hugely【C2】______to divers navigating shark-filled waters, scientists found that the predator — like dolphins, seals and whales — is unable to distinguish between colours.
It can only see in black and white, so swimmers would be best off wearing a light blue wetsuit that【C3】______the colour of the water.
Costumes or wetsuits that camouflage(伪装)swimmers’ bodies in the sea water are less likely to【C4】______a shark’s attention than ones with bright, solid colours that【C5】______their outline.
Professor Nathan Hart, from the University of Western Australia, said "It’s the high【C6】______against the water rather than the colour itself which is probably【C7】______to sharks".
The researchers examined the eyes of dead sharks and found they had only one type of photoreceptor(感光器)in the retina(视网膜),【C8】______they could only see in monochrome(单色).
The U.S. Navy has conducted tests that suggested sharks were able to see yellow most【C9】______. 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【C10】______for sharks.
He said "It may be possible to design swimsuits and surf craft that have a lower visual contrast to sharks and are therefore less attractive to them".
A)attractive I)emphasize
B)predicting J)concentration
C)victim K)matches
D)beneficial L)contrast
E)effectively M)clearly
F)corresponds N)visibility
G)indicating O)sensitive
H)draw [br] 【C8】
选项
答案
G
解析
此处填现在分词。分析句子结构和句意可知所填词应该为现在分词,与后面的内容构成分词短语作结果状语,从备选项B)、G)中选择。根据空格前的内容可知,它们只能看见单色是有证据的,因此B)predicting不符合语境,G)indicating意为“表明”,能使文意通顺,故为答案。
