　　【答案】　A

　　D

　　Happy? Angry? Anxious？How can we measure animals' emotions? A new study of animals' emotions suggests that，as in humans，emotions can tell animals about how dangerous their world is，and guide the choices that they make.The article of the study by Bristol University's Professor Mike Mendl is published online.

　　An animal living in an environment where it is often threatened by predators will develop a negative emotion or “mood”，such as anxiety.However，one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state.

　　The researchers say that these emotional states not only show the animal's experiences，they also help it decide how to make choices，especially in unclear situations，which could have good or bad results.An animal in a negative mood state will make a safety­first，“pessimistic” response to an unclear event—for example，it considers a noise in the grass as a signal of a predator—while an animal in a positive mood state will benefit from a more “optimistic” response，considering the noise as a signal of prey.
