翻译题 46.What is artificial intelligence today? Roughly speaking, it's technology that takes in huge amount of information from a specific domain (say, loan repayment histories) and uses it to make a decision in a specific case (whether to give an individual a loan) in the service of a specified goal (maximizing profits for the lender). These tools can outperform human beings at a given task.
This kind of A.I. is spreading to thousands of domains (not just loans), and as it does, it will eliminate many jobs. Bank tellers, customer service representatives, telemarketers, stock and bond traders will gradually be replaced by such software. Over time this technology will come to control semiautonomous and autonomous hardware like self-driving cars and robots, displacing factory workers, construction workers, drivers, delivery workers and many others.

【正确答案】今天的人工智能是什么?大致来说，它是一种从特定领域(例如贷款偿还记录)获取大量信息，并利用这些信息在特定情况下做出决定(是否贷款给某人)，服务于特定目标(让贷方实现利润最大化)的技术。执行特定任务时，这些工具的表现可以好于人类。
这种人工智能正拓展至成千上万个领域(不只是贷款)，在此过程中，它会让很多工作岗位消失。银行出纳员、客服代表、电话推销员、股票和债券交易员都将逐渐被此类软件取而代之。假以时日．这种技术将会控制自动驾驶汽车、机器人等半自动化和自动化硬件，取代工厂工人、建筑工人、司机、快递员以及其他很多职业的从业者。

【答案解析】(1)本句的主干为it’sd technology…that，由and引导的两个定语从句进一步解释说明technology。from a specific domain和in a specific case为介词短语作后置定语分别限定information和decision。take in译为“获取”，specified译为“特定的”。
(2)as it does中as引导时间状语从句，does指代前面的动词spread，其整体可译为“在此过程中”。spread原意为“传播，散布”，这里可理解为“拓展”，eliminate译为“淘汰”。
(3)本句的主干为this technology will come…。like后举例说明semiautonomous and autonomous hardware的内容，displacing…为现在分词引导结果状语。semiautonomous原意为“半自治的”，因其后接hardware(软件)，故这里可理解为“半自动化”。overtime译为“假以时日”。
