People tend to become more personal and hide less of themselves when using e-mail. Researchers from Open University in Britain have found in a recent study that there are good reasons for this.

　　　 The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: If only five people in the world could be saved from a world disaster, who should they be? The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with (安装) cameras so that students could see each other, this limited the personal side of the conversation.”

　　　 Generally the information was not extremely personal. It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.

　　　 Dr Johnson believes that e-mailing encourages people to focus on (专注于) themselves. And when they do this, they become more open, especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself. This is because you are not thinking what the other person is thinking of you. So e-mailing has become the modern way of talking,” said Dr. Johnson. However, this style of talking is not entirely new. “In the 19th century people started to use the ‘telegraph’ to communicate. Now the same kind of thing has happened and people ended up speaking more freely.”

　　　 Dr. Johnson thinks that e-mailers need to know about these effects of e-mailing, especially when they start work in a company. “If you don’t know about it, you could find yourself saying more about yourself than you wanted to.”

I recently spent two years in the Arctic (北冰洋) filming the series (系列节目) Blue Planet. I love being in an environment that hasn't changed for 20,000 years. Of course it's freezing, but it must be a healthy place because you never catch colds.

When I'm filming, I like to really feel how lonely the environment is. Filming underwater involves (包括) cutting through thick ice and diving in tied to a line. The person at the other end has to be ready to pull you out fast if necessary.

Originally I was a research diver for the British Antarctic Survey project, but for me science lacked excitement. I'd always enjoyed photography, and whenever camera teams passed through, they encouraged me to watch and learn. I was then able to move into filming in 1985 and have concentrated on(专门从事)Arctic and Antarctic wildlife ever since.

I prefer to be faced with the animals I'm filming. I haven't got in the water with killer whales (鲸鱼) yet, but I plan to. Of course, it's dangerous if you choose the wrong moment. They're big animals and can move fast, so I'd be stupid to film them searching for food!

I've never had problems with polar bears, although once I was frightened when one tried to get into my tent. Polar bears are bold(　勇敢), clever and dangerous. But I made this one see I wasn't about to attack it ---- I'm sure it realized I wouldn't hurt it.

When I come home back from my trips, I work in the mornings and spend the afternoons swimming to keep fit. Now I'm fifty, filming is harder. The challenge for me is to continue to deliver (交付) high-quality work (作品).
