????这家炼油公司一直都在通过收购来实现增长。2012年，它斥资25亿美元（153.5亿元人民币）买下了英国石油（BP）设在加利福尼亚州南部的炼油和营销业务。这笔交易能让Tesoro的炼油能力提高近40%，成为加州炼油行业的主导者，但它还需通过反垄断审核。收购计划公布后，Tesoro的股价不断上涨。

????The oil refining company has a history of growing through acquisitions, and in 2012 it bought BP's refining and marketing business in southern California for $2.5 billion. The deal, which is pending an antitrust review, should increase Tesoro's refining capacity by nearly 40% and allow the company to be a dominant player in the state. The shares moved higher after the acquisition was announced.
