单选题 The words“ this faculty”(Line 3，Para．4)refers to the sea cucumbers ability to__________．

A．squeeze into crevices
B．devour all available food in a short time
C．suck up mud or sand
D．1ive at a low metabolic rate

参考答案D
解析: D。本题考查the faculty的指代含义，出题点在条件句式处(Although…)。根据题干信息词定位到原文第四段。第四段首句提到，虽然它们食欲极佳，日夜不停地吃，但是海参也有能力停下来并且将新陈代谢率降到很低的水平，这样提供给它们食物的其他生物有机体就有机会繁殖了。接下来第二句提到，如果不是因为这一本领(If it were not for this faculty…)，它们就会在短时间内吃掉所有可吃的食物，最后很可能会饿死。由此可知this faculty就是指前文的the capacity to become quiescent and live at a low metabolic rate，即指它们能把新陈代谢率降到很低的水平，故选D。
