Chinese shrimp (蝦) move their tails less vigorously to preserve energy in lower oxygen environments. Some creatures, such as jellyfishes, are more tolerant of low oxygen than others are. But all animals will feel the impact of deoxygenation because they all have evolved their oxygen capacity for a reason, says Oschlies. Any drop in oxygen is going to damage survivability and performance, he says.（1）According to the first two paragraphs, what worries scientists the most? A.Salty water holds less gas in the increasingly warmer ocean.（3）What can be inferred from the passage? A.一些最近的研究表明，在過(guò)去的50年里，一些熱帶地區(qū)的氧氣含量下降了驚人的40%。所以表面的極地冰水阻止氧氣下沉是海洋缺氧的原因之一。 （4）考查主旨大意。From electric cars.（2）Whom may be the Ecocapsule initially designed for?
