易导致病人死亡的常见原因是（）。
听力原文：W: Wasn't that a terrific lecture on dolphins？ I didn't know that dolphins traveled in such large groups, or were able to communicate with other members of their group with those whistle-like sounds.
M: And they also use clicks as a sort of sonar.
W: I really couldn't understand that part of the lecture. You could？
M: Yes, the dolphins use clicks to identify objects in the water; they can even identify tiny objects more than 100 meters away using these clicks. Scientists believe that a dolphin may even have a sonar-like image in its brain of a distant object so that it can identify the object long before the dolphin can actually see the object.
W: So the dolphins use these clicks mostly to identify objects in the water？
M: I think so, and they have considerably more ability to do this than humans do.
W: It is hard to believe that, in addition to these sonar clicks, dolphins are actually learning some human language.
M: Yes, I believe that the lecture said that some dolphins had already learned around fifty human commands, and that those dolphins were able to understand not only individual words but words clustered together in sentences!
W: Dolphins must certainly be amazing animals to do all of that.
M: I'm sure they are, and we're only just beginning to find out how intelligent they are.
