Classic mass marketing works on the belief that people—as consumers—will behave "_____31____" when faced with purchasing decisions.Traditional marketing assumes that consumers will systematically consider concrete product factors like price, features, and utility. Sensory marketing, by contrast, seeks to ___32_____ the consumer's life experiences and feelings. These life experiences have ______33___ sensory, emotional, cognitive, and behavioral aspects. Sensory marketing assumes that people, as consumers, will act according to their emotional impulses more than to their _____34____ reasoning. In this way, an effective sensory marketing effort can result in consumers choosing to buy a certain product, rather than an equal but less expensive_____35_____.For the Harvard Business Review in March 2015, sensory marketing pioneer Aradhna Krishna wrote, “In the past, communications with customers were essentially monologues—companies just ‘talked at’ co nsumers. Then they____36___into dialogues, with customers providing feedback. Now they’re becoming ___37_____conversations, with products finding their own voices and consumers responding ____38_____ to them.”Sensory marketing attempts to ensure lasting product success by:●Identifying, measuring, and understanding consumers' emotions●Identifying and capitalizing on new markets●Ensuring first and repeated purchases (brand ____39_____)According to Iowa State University Professor Jihyun Song, consumers relate various brands to their most ____40___ experiences—good and bad—with their buying behaviors driven by "storytelling and emotion." In this manner, sensory marketers work to create emotional ties that link the consumer to the brand.31~40.

高三数学模拟冲刺试卷答案
一、选择题（本大题共10小题，每小题5分，共50分）1. 已知函数f(x) = x^3 - 3x + 2，则f(x)的对称中心为（）A. (0, -1)B. (0, 2)C. (1, 0)D. (1, 2)答案：A解析：函数f(x) = x^3 - 3x + 2的对称中心可以通过求导找到极值点，然后求出对称中心。
f'(x) = 3x^2 - 3，令f'(x) = 0，解得x = ±1。
由于f(x)在x = 0处取得极小值，故对称中心为(0, -1)。
2. 下列不等式中正确的是（）A. a > b 且 c > d 则 ac > bdB. a > b 且 c < d 则 ac > bdC. a > b 且 c > d 则 ac < bdD. a > b 且 c < d 则 ac < bd答案：A解析：由不等式的乘法性质，当a > b且c > d时，两边同时乘以正数，不等号方向不变，故ac > bd。
3. 已知等差数列{an}的首项为a1，公差为d，则第10项与第15项之和为（）A. 10a1 + 14dB. 15a1 + 14dC. 10a1 + 15dD. 15a1 + 15d答案：C解析：等差数列的第n项公式为an = a1 + (n-1)d，所以第10项与第15项之和为a10 + a15 = (a1 + 9d) + (a1 + 14d) = 2a1 + 23d = 10a1 + 15d。
4. 下列函数中，在定义域内单调递增的是（）A. y = 2x - 1B. y = -x^2 + 1C. y = x^3D. y = e^x答案：D解析：函数y = e^x在定义域内是单调递增的，因为其导数y' = e^x始终大于0。
5. 已知等比数列{bn}的首项为b1，公比为q，则第5项与第8项之比为（）A. q^4B. q^3C. q^2D. q^5答案：A解析：等比数列的第n项公式为bn = b1 q^(n-1)，所以第5项与第8项之比为b5 / b8 = b1 q^4 / (b1 q^7) = q^4。
