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] 【C1】
选项
答案
C
解析
此处填名词。空格前面的内容提到鲨鱼是完全色盲的,它们能清楚地看到的东西大都是亮色的和黑色的,so后面表示的是结果: “因此穿淡蓝色的和海水颜色相配的颜色的人不太可能成为鲨鱼攻击的受害者”能使句意通顺,因此答案为C)victim。
