阅读理解 Andra Rush,a member of the Mohawk Indian tribe (部落) of Ontario,Canada,was raised 30 miles outside Detroit,not far from her grandparents and their Ontario reservation (印第安人保留地)．When the teenage Rush visited the reservation for the first time,she was struck by the poverty and lack of hope. 'I really wanted to make a difference,'she says. She graduated  from  the University of  Michigan in 1982  and took a nursing job . But she was disappointed with the low pay,and within a year she was pursuing an MBA.That summer,she interned (作实习生) at an air freight (货运) company,where the speed of package pickups and deliveries drove profits.'I thought I could do that better,' Rush says. She used her credit cards and borrowed $5,000 from her parents to buy a van and two used pickup trucks.She accepted every delivery job that came her way,and worked nursing shifts on weekends. Within six months,Rush had ten employees,and customers like Ford and GM were paying her to fetch small packages from the airport.Ford was the first to offer her a job trucking parts between its plants and suppliers. Rush _ kept _ a _ single－minded _ focus _ on _ meeting _ deadlines -no matter what.In the wake of 9·11,when increased security stalled (拖延)  traffic for hours on Detroit's  largest  bridge, she hired ships to get  her trucks across the Detroit River. By 2001,many of Rush's 1,000 employees were Native Americans,working alongside people of every background.But she felt she hadn't done enough.So she joined forces with a Canadian parts maker to design and fit auto parts.She located the plants near reservations,creating opportunities where they were needed most.By 2009,her auto parts business was bringing in $370 million. Rush is 49 now and still working hard.'I love my job,'she says.'I like the fact that you can keep challenging yourself-and then suddenly you lift your head and it's been 25 years.' 1．When first visiting the reservation,young Rush felt__________.
