24. Intricately intertwined with(与……错综交织) self-esteem and inhibition and risk-taking, the construct of anxiety, as it has been studied in the psychological domain(领域), plays an important affective role in second language acquisition. Anxiety is almost impossible to define in a simple sentence. It is associated with feelings of uneasiness, frustration, self-doubt, apprehension(恐惧), or worry. Scovel defined anxiety as “state of apprehension, or vague fear…” We all know what anxiety is and we all have experienced feelings of anxiousness. How does this construct relate to second language learning? Any complex task we undertake can have elements of anxiety in it, aspects in which we doubt our own abilities and wonder if we will indeed succeed. Second language learning is no exception to a long list of complex tasks that are susceptible(易受感染的) to our human anxieties.The research on anxiety suggests that, like self-esteem, anxiety can be experienced at various levels. At the deepest, or global level, trait anxiety is a more permanent predisposition(倾向) to be anxious. Some people are predictably and generally anxious about many things. At a more momentary, or situational level, state anxiety is experienced in relation to some particular event or act. As we learned in the case of self-esteem, then, it is important in a classroom for a teacher to try to determine whether a student’s anxiety stems from a more global trait or whether it comes from a particular situation at the moment.Trait anxiety, because of its global and somewhat ambiguously defined nature, has not proved to be useful in predicting second language achievement. However, recent research on foreign language anxiety, as it has come to be known, focuses more specifically on the situational nature of state anxiety.(10分)24.1 The passage mainly talks about ______.(2分)A. anxietyB. inhibitionC. risk-takingD. self-esteem

“曼陀铃”公司是一家饮料生产企业。公司未做任何市场调查,片面认定年轻消费者大都注重绿色、营养和健康,因此针对年轻消费者推出一款“低糖”、“不含防腐剂”的“原生态”果蔬饮料。该公司认为自己的产品只要质量好、有特色,就一定会获得消费者的青睐在推出该产品时,公司决定采用较高的价格,同时认为这样“好”的产品无需进行大量促销宣传,消费者也会趋之若。结果出乎公司意料的是,该产品上市后购买者寥寥无几。究其原因,首先是消费者对该产品不了解;其次是消费者对该饮料的“原生态”口味很难接受,导致该产品退出市场再无声息。问:(1)结合案例分析该公司奉行的市场营销哲学。(5分)(2)结合案例分析该公司在产品导入期采取的营销策略。(5分)
