托福阅读背景知识:常见爬行动物

  ♢ based on 依据....

  ♢ fossil specimens 化石样本

  ♢ publish 出版,发行,发布

  ✎ Atopodentatus apparently used chisel-like teeth along the edge of its blunt, hammer-shaped snout to scrape algae off hard underwater surfaces. It then quickly opened its mouth to create suction before closing its jaws to filter the plant material through densely packed and needle-shaped teeth much like baleen whales strain tiny shrimp-like krill from seawater.

  显然,A是沿着它钝的锤子形状的鼻子的边缘用凿子似的牙去剐蹭掉水平面下的海藻硬的表面,然后迅速的张开大嘴吸进去。在闭嘴之前用紧密的、针状的牙齿过滤掉植物体,就像须鲸从海水中获取磷虾一样。

  注:这种描述细节的句子,不管是程度好还是差的学生读起来都觉得难,不过好在托福阅读并不是特别喜欢考这种细节!更倾向于考查你抓重点、关键词的能力!

  ♢ scrape off 刮掉

  ♢ suction 吸力

  ♢ filter 过滤

  ✎ When thinking of hammerhead creatures, sharks may come to mind. But Atopodentatus' hammerhead feature differed in location and function from the sharks, whose eyes are on the end of lateral extensions on their head.

  当想到凿子头生物,我们会想到鲨鱼,但是A的凿子头特点在位置和功能上与鲨鱼不同,它的眼睛位于从头部侧面延伸出去的末端。

  ♢ come to mind 出现在脑海中

  ♢ lateral 侧面的,横向的

  ✎ Atopodentatus appeared during the Triassic Period relatively soon after the biggest mass extinction of species in Earth's history, illustrating that life was bouncing back nicely. Other oddball creatures also swam the seas at the time, including a reptile called Dinocephalosaurus whose neck comprised half of its 17-foot (5.25 meters) length.

  Atopodentatus出现在三叠纪时期,紧随生物大灭绝后,表明生物有很强的恢复力。在那时还有其他海洋中的怪异生物,如脖子占全长的一般的D这种爬行动物。

  ♢ bounce back 反弹,迅速恢复活力
