TPO 10海洋生物学这篇听力文章出现了一个5选3的题目
○ It had an elongated skeletal structure
○ It strongly resembled a modern hippopotamus
○ It had an unusually kind and thintail for a whale
○ It had limbs that could have been used for walking
○ Its skull had ear bones characteristic of land mammals
三个红色标注的选项就是答案，做对这道题，同学们需要关注平行结构行文意思中出现的also这样的词汇，在笔记中记录这些层级结构词前后出现的名词，这样就不难选出3个对应的选项。
The name Ambulocetus natans comes from Latin of course, and means “walking whale that swims”. It clearly had four limbs that could have been used for walking. It also had a long thin tail, typical of mammals, something we don’t see in today’s whales. But,italso had a long skeletal structure. And that long skeletal structure suggests that it was aquatic.
另外，本篇文章中多处出现but和contradict这样的转折词汇，在听力考试中，转折词汇出现的地方往往会有考点，需要同学们特别加以注意。
