2020年7月六级真题答案※ 微信对答案

　　Conversation 1

　　M： Tonight， we have a very special guest. 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： 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 have 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. 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 a two-hundred-meter swimming race.

　　M： 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 is no stopping technological progress but， as I said， each situation should be considered carefully on a case-by-case basis.

　　Questions 1-4 are based on the conversation you have just heard.

　　Question 1： What do we learn about Anna Sanchez?

　　Question 2： What is the woman's book mainly about?

　　Question 3： What has changed in the past thousands ofyears?

　　Question 4： What is the man's concern about the use of technology in sports competitions?
