Question 1 is based on the conversation you have just heard.

M: Tonight, we have a very special guest. (1) [Mrs. Anna Sanchez is a three-time Olympic champion and author of the new book To the Edge.] Mrs. Sanchez, thank you for joining us.

W: Thank you for having me.

M: Let’s start with your book. What does the title “To the Edge” mean? What are you referring to?

W: (2) [The book is about how science and technology has helped push humans to the edge of their physical abilities.] I argue that in the past 20 years, we’ve had the best athletes the world has ever seen.

M: But is this a fair comparison? How do you know how, say, a football player from 50 years ago would compare to one today?

W: Well, you are right. That comparison would be perhaps impossible to make. But the point is more about our knowledge today of human biochemistry, nutrition, and mechanics. (3)[ I believe that while our bodies have not changed in thousands of years, what has changed is the scientific knowledge. ]This has allowed athletes to push the limits of what was previously thought possible.

M: That’s interesting. Please tell us more about these perceived limits.

W: The world is seeing sports records being broken that could only be broken with the aid of technology, whether this be the speed of a tennis serve or the fastest time in a hundred-meter dash or 200-meter swimming race.

M: (4)[ Is there any concern that technology is giving some athletes an unfair advantage over others? ]

W: That is an interesting question and one that has to be considered very carefully. Skis, for example, went from being made of wood to a metal alloy, which allows for better control and faster speed. There’s no stopping technological progress. But, as I said, each situation should be considered carefully on a case-by-case basis.

1. What do we learn about Anna Sanchez? （关于安娜·桑切斯，我们可以了解到什么？）

解析：A。四个选项都是在说She的职业，推测题目问的是女士的情况，听音时应注意与女士职业相关的信息。录音一开始，男士就说今晚将有一位特别嘉宾，安娜·桑切斯夫人，她是三届奥运会冠军，由此可知，女士是一名运动员，因此选A。

错项排除：B项中的speaker和D项的inventor，在录音中并没有与之相关的信息，故均可排除。录音中女士提到science and technology，是用来说明科技对运动员的影响，并不能说明女士是科学家，C项的scientist利用女士提到的science作干扰，故排除。
