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] 【C7】
选项
答案
A
解析
此处填形容词或分词。该空答案可从最后一段得出,根据最后一段中Hart的话可知物体视觉对比度的高低影响着它们是否能吸引鲨鱼的注意力,空格所在句表达的意思与此相同,空格处所填词应是attractive的同义复现或原词复现,故答案为A)attractive。
