Listen to five speakers talking about why they became scientists. Which job in Exercise 2 does each person do? (Lắng nghe năm diễn giả nói về lý do tại sao họ trở thành nhà khoa học. Mỗi người làm công việc nào trong bài tập 2?)

1. Nobody's surprised that I studied languages - my father's an English teacher and my mother's a translator. At high school, my best subjects were Spanish and German, but I wanted to know more about the nature of language and communication. So I studied linguistics and computer science at university. I'm interested in artificial intelligence - I've just published my first research paper on robots and how they communicate.

2. I work with people who have new ideas about energy sources, like solar and wind power. We're doing research into climate change and trying to discover new ways to produce energy. I want to study ways of protecting the environment using modern technology. This is important work for the future of the planet.

3. I always want to understand why people do what they do - why do they behave that way? What are they thinking? I'm interested in how we develop from birth to the age of seven. Those seven years are the most important years for the psychological development of a child. I love doing research and analysing data. When I finish my studies, I want to work in a children's hospital.

4. I became interested in archaeology when we were studying ancient Egypt and mummies in school. It was fascinating. When I was fourteen, my class took a school trip to Paris and we visited the famous museum, the Louvre. I spent hours in the Egyptian room and decided that I wanted to know more about people who lived thousands of years ago.

5. The first time I went scuba diving, I saw a little fish swimming away into the distance, and at that moment I thought “Oh yes, that's what I want to do - I want to explore oceans, collect evidence about global warming and help to protect marine life,” I love my work - I can't understand why everybody isn't doing my job.
