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
【C9】
选项
答案
M
解析
此处填副词。所填词用来修饰see。前文提到亮色更能吸引鲨鱼的注意力,倒数第五段和最后两段都提到了视觉对比度对吸引鲨鱼注意力的作用,由此可知空格所在句应该是说鲨鱼能非常“清楚地”看到黄色,clearly符合文意,故答案为M)clearly。
