题型:单项选择题

Growing up on a tobacco farm, Emma Avery was used to hard times. When she was seven, her family’s farmhouse burned to the ground. Her father made a temporary (临时的) shelter, where eight people had to sleep in two beds. As soon as Emma and her four brothers and two sisters were big enough, they were out in the fields.

Emma would find her comfort in school, even as a C student, thanks to one teacher. When she moved on to middle school, Emma was alarmingly far behind her classmates. She kept her head down, trying not to be noticed, struggling to catch up, and feeling like an outsider.

Then one day, when Emma was 16, a teacher named Mr. Potts changed everything. Looking his students in the eye, Mr. Potts said, "Being a C student does not mean you do not have a valuable contribution to make. Some of you have to work in the fields in the evening and do not have time to study. But if you do your best, you have a gift to give."

The teacher’s words made Emma believe she could do well, and she worked harder. In the end she won a scholarship to St. Paul’s College, graduated with a degree in elementary education in 1967, and got a job in the public-school system. Then, at George Washington University, she received a master’s in education in 1970, and afterwards in the same year she married Ron Smothers.

Over the next six years, Emma taught in public schools in Miami. In 1976, after saving $10,000, she opened her first restaurant in Los Angeles. Eventually Emma stopped teaching, and her business expanded (扩展) to six restaurants.

In gratitude (感激) for what she has been able to achieve, Emma donates a lot. She has no idea how much money she’s given away. She says, "Those I want to help are the C students who just need help, direction and confidence."
