Unit 3 Under the sea Ⅰ 阅读理解 A （2018·四川成都高中毕业班检测） Fans of the movie Finding Nemomay remember the terrifying fish that scares Dory and Marlin at the bottom of a trench. But in reality this “monster ”， a black seadevil ， is only about 9 cm long ， which would make it about a third of the size of Dory and potentially smaller than Marlin or Nemo. While this inaccuracy may seem harmless ， it could cause problems for future conservation efforts ， as people are more likely to support conservation of adorable rather than scary - looking animals. The black seadevil is just one of the mysterious “ monsters ” . From 2000 to 2010， scientists described about 1 ， 200 new species in the Census of Marine Life. While this figure may seem astonishing ， a further 5 ， 000 individual dead creatures are in specimen （标本） jars ， waiting to be described. Specimens must be methodically collected ， identified ， and then the identity of new deep - water species must be confirmed. If we call unusual deep - sea animals monsters ， then we may harm their conservation as people are unlikely to be connected with them or care about saving them. On the other hand，their rarity clearly makes them popular on social media sites. For other species ， this has already resulted in increases in illegal trading for unusual pets. Deep-sea species may potentially become illegally obtained specimens or food. Humans may end up eating these animals of the deep sea to extinction before their species are even known to science. Every habitat on earth is interconnected ， and whatever we as humans do has an influence on marine ecosystems. In reality ， about 80% of our oxygen is produced by microorganisms （微生物） in the oceans. This makes our oceans both the lungs and lifeblood of our planet and we must all try harder to save them. 【解题导语】 本文主要从电影里对深海物种的不准确认识， 谈到了保护深海物种的重 要性。 1 1.What can we know about the black seadevil in reality ？ A.People benefit greatly from the oxygen produced by it.
