阅读理解。 When Nancy Lublin received $5,000 from her grandfather in 1996, she never once considered taking a vacation or paying off student loans (贷款). Instead, the 24-year-old New York University law student began thinking about helping low-income women get better jobs. 'If a woman goes for a job interview (面试) poorly dressed, she won't get the job, ' Lublin says.'But without a job, she can't afford suitable clothes.' So, with the money Lublin founded 'Dress for Success' and began collecting women's clothes which were still in good condition but which their owners no longer needed. 'So many women have clothes lying around that they will never wear again,' one of Lublin's assistants says 'Nancy's idea is so simple and yet so important to women.' Many women come to Lublin's office before going to a job interview. Here, they receive a suit, shoes and any other things they need, Since it was set up, more than 1,000 women have turned to 'Dress for Success' for help. Many of them have won job.
