2018-2019学年高二英语下学期周测试题(3.18-3.24，无答案)一、阅读理解（本大题共5小题，共10.0分）FOR us humans， one of the greatest experiences is to taste all kinds of delicious food But for penguins， they cannot get a taste of this happiness Thats because penguins cant actually taste the delicious flavors （味道） of their favorite food-fish! Scientists from the University of Michigan examined the genome （基因组） of five species of penguins They found that not one can taste umami （鲜味）， the flavor of meat or fish， the BBC reported Many animals have five basic tastes： sweet， sour （酸）， salty bitter （苦） and umami But according to genetic（遗传的）data， penguins are believed to have only sour and salty tastes These findings are surprising and puzzling And scientists dont have a good explanation for them But they have a few ideas First， one of the umami genes doesnt work in cold temperatures Its about zero degrees when they eat cold fish， Zhang Jianzhi， the lead scientist， told the Daily Mail， so even if the penguins had a functional（功能的）gene， it might not work when they needed it Plus， penguins tongues are very special which may have something to do with their lack of taste Instead of being covered with taste buds which help to taste food， penguins tongues are extremely spiky （钉子似的） This is better for them to hold slippery （滑的） fish than tasting them One study even showed that some types of penguins dont even have taste buds， But penguins seem to be managing just fine Their behavior of swallowing food whole and their tongue structure and function suggest that penguins need no taste perception（知觉）， said Zhang1.
