第一节阅读下面两篇语言材料,然后按要求做题。(共10小题;每小题2分,满分20分)

A

Molly Wilson had been a dancer and a mother for many years when she decided to sail round the world to raise money for charity.

As a child she had trained as a ballet dancer, but at l5 she had grown too tall for classical ballet, so she became a member of a pop dance team.

She got married, and after she had children she retired from show business to bring them up. They grew up, and when they were 18 they left home.

She says, “When I decided to do the round-the-world race, my husband thought I was bored because the children had left home. He was also worried because I had never sailed before. I was not bored, but I had met some people who told me about the race. They had taken part in it, but they had only done one section, say, from New Zealand to Australia. I wanted to do the whole ten-month journey. ”

Before Molly left she did a lot of training, but it hadn’t prepared her for the worst weather which they experienced. By the end of October last year, she had raised more than $50,000 for charity.

She says, “Sometimes I ask myself, what did I do? How did I do it? But then I think, it’s the same as being a dancer. Before I left on trip, I had trained hard. I had got very fit and had prepared myself completely. Then on the trip I was simply a good team member.”
