Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface Or did she throw away goods that she didn’t need in order to travel lighter
Over 100000 people with "gold fever" made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.
The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.

According to this passage, many people who went to Alaska ______.

A. eventually became millionaires
B. brought with them many shoes
C. had conflicts with the Eskimos
D. were not properly equipped

ABC公司是一家炼油公司,它通过自己旗下的ABC公司加油站出售自己的产品。ABC公司进行了市场调研后认为汽油市场60%的份额由“服务导向型客户”占领。这些客户属于中高收入阶层,当加油站能够提供优秀的客户服务,如整洁的设施、便利店、态度友好的员工、快速服务、能够用信用卡付款以及提供优质高辛烷汽油时,他们愿意支付较高的汽油价格。剩余40%的市场份额由那些寻找最廉价汽油的“货比三家者”组成。ABC公司的战略是以60%的服务导向型客户为主要目标。ABC公司2012年度平衡记分卡如下。为了简洁起见,我们省略了为实现每个目标而采取的计划。
