问题 Fear is a normal, legitimate response to genuine danger. However, when fear spirals out of control, becoming persistent and irrational, it constitutes a phobia. Phobias affect a significant portion of the American population. Some experts believe that nearly twenty-five percent of Americans live with irrational fears that prevent them from performing everyday activities. Phobias, like other anxiety disorders, can greatly affect quality of life. Generally defined as an unrelenting, anomalous, and unfounded fear of an object or situation, a phobia is normally developed from a past negative experience or encounter. Children might adopt phobias by observing a family member’s reaction to specific stimuli. There is also data to suggest genetic factors linked to phobias.
It can be inferred from the passage that theories about phobias contain which of the following elements?
选项 A、There is a qualitative difference between ordinary fear and phobia.
B、Nearly three quarters of Americans live their lives unaffected by phobias.
C、Tendencies to develop phobias may be inherited.
答案A, B, C
解析 The best answer is A, B, and C. Choice A is supported by the second sentence of the passage. Choice B is implied by the fourth sentence. Choice C is supported by the last sentence.
