　　Mr. Jobs, following his return to the company in 1997, hired Mr. Cook in 1998 to oversee the manufacturing of Apple's computers. Before that, the Alabama native, who majored in industrial engineering at Auburn University and earned a master's in business administration at Duke University, had worked in operations at Compaq Computer Corp.

　　At Apple, Mr. Cook shed bloated inventories and whipped the company's supply chain into shape. He rose to become the No. 2 executive at Apple under Mr. Jobs. Beginning in August 2004, Mr. Cook ran Apple for two months while Mr. Jobs recuperated from surgery to remove a cancerous tumor from his pancreas.

　　Mr. Jobs later gave Mr. Cook responsibility for Apple's world-wide sales and its Macintosh computer division. In 2005, he was appointed chief operating officer. In 2009, he stepped in for Mr. Jobs again; Mr. Jobs went on medical leave for the first half of the year and and had a liver transplant.

　　Mr. Cook ran day-to-day operations during Mr. Jobs's absence and was praised for his ability to make Apple's sprawling operations move on time. He has established himself as the CEO-in-waiting since his stint taking over for Mr. Jobs.

　　在乔布斯休病假期间，库克负责公司的日常运营，他令苹果庞大的业务正常运转的能力得到了赞扬。他自从短暂接替乔布斯以来，已确立了自己的CEO接班人地位。

　　Several people who do business with Apple say their dealings with the company during Mr. Jobs's 2009 leave remained unchanged and that products continue to be developed and released on schedule.

　　数名与苹果有商业往来的人士说，2009年乔布斯病假期间，他们与苹果公司的往来没有变化，产品仍然按计划开发和发布。

　　For 2010, Mr. Cook took in a salary of $800,000 in 2010 along with a $5 million bonus and $52.3 million of stock awards. His total compensation was slightly more than $59 million.

　　2010年，库克工资收入80万美元，另有500万美元奖金和5,230万美元的股票奖励。他的薪酬总额略超过5,900万美元。

　　More recently, investors have expressed concerns that Mr. Cook might be lured to a competitor. In recent years, Mr. Cook has been the target of overtures from other technology giants in the past: Motorola Inc. tried to hire Mr. Cook while Dell Inc. wooed the executive, according to people familiar with the situation.

　　不久前，投资者表达了对库克可能被一家竞争对手挖走的担忧。据知情人士透露，近年来，库克曾一直是其他科技巨头主动示好的目标：摩托罗拉(Motorola Inc.)曾试图聘用库克，而戴尔(Dell Inc.)也曾向其示好。
