constricted = con(一起) + strict(拉紧) + ed(形容词) = 压缩的，受限制的
anchor = anch(弯曲) + or(器物) = “弯曲”物→锚→[用来]固定

来源于：听力OFFICIAL21 L5So, if there are no truly non-venomous snakes, were the so-called non-venomous snakes, like constrictors and pythons, were they venomous at some point in their evolution?
因此, 如果说没有真正的无毒蛇类的话, 那么像蟒蛇, 蚺蛇这类所谓的无毒蛇类难道是在进化中由有毒进化为无毒吗?
来源于：听力OFFICIAL21 L5Constrictors have evolved to kill their prey by crushing, but perhaps they once were venomous, and then at some point their venom-producing apparatus wasn’t needed anymore, so it gradually disappeared.
蟒蛇是通过缠绕挤压来进行捕猎，也许它们曾经是有毒蛇类，而它们施放毒液的器官又在某种程度上无关紧要，所以便逐渐消失了。
