课后提升练(四) Section Ⅳ　Writing [对应学生用书P157] Ⅰ.阅读理解 (2022·陕西汉中高二期末)Nicolas Maire is the model of a professional French chef with years of experience.To help perfect the flavors of the innovative foods，Mr Maire has a new assistant chef in the form of Sum, an artificial intelligence robot. Along with a team of flavorists, Sam helps blend a huge group of flavors for clients.In humans the sense of taste stems from multiple receptors(感受器) that are ready to make our brains aware of the nature of any possible food we encounter.Sam lacks this sense of taste, but it has been trained on a database of ingredients gathered over 60 years at the company of Firmenich, a business with a perfume industry origin stretching back to 1895.Using a technique called machine learning, it has raced through examples of flavor combinations and has learnt its own definitions, maturing over 18 months into today's AI robot. Eric Saracchi runs the digital side of Firmenich.“Flavors are more complex than perfumes，” he says, “and Sam had to understand what a strawberry is or how roasted beef hits the tongue, before finding matches between tastes and foodstuffs.” One big advantage of an AI robot is that it has no cognitive bias(认知偏见).This lack of human prejudices helps Firmenich to get past any unconscious leaning of the flavorists.The objectivity of Sam, lacking influences that can affect even the most professional flavorists, allows it to work at speed．“It adds value by combining the knowledge of all the other flavorists here，” says Saracchi. The machine rapidly gives an indication of how a flavor can be created and how much of an ingredient should be included．And Sam can hold the line between Saracchi's team of flavorists and public tastes, refereeing decisions when the flavorists' view differs from that of a consumer group. 【语篇解读】本文是一篇说明文。文章讲述了厨师们利用人工智能机器人Sam来让食品的口味变得更加完美。 1．What does Sam do together with many flavorists?
