雅思口语P2 Describe an interesting talk or lecture(新题目)(文字版)

Mention about the subject, a talk that I have heard has got to do something with personal safety on the Internet. You know, I got to know this lecture a couple of years ago when I was a sophomore. I was arranged to take part in this special speech, and at the beginning I thought it was quite boring, you know. I didn't have interest at all. It was probably in the teaching building, I couldn't remember that clearly. You know, it has been a long time. But the content was quite practical. According to this lecture, I had a clear view of the potential dangers on the Internet, cuz I was most likely to put my personal photos and name or such on certain website, such as sharing them with my friends or making friends, getting to know new net pals. The lecture introduced me a number of dangers and problems of doing so. The lecturer certainly got the sense of humor as well. He took some examples in a funny way. So, it was a quite impressive lecture and influenced me a lot. That is it.
