Good afternoon, everyone.
I am glad I have the chance to come to your prestigious
school to give a talk about saving energy. I will start by giving you an outline of my
talk. First of all, you will hear about how to save electricity. Second, I will talk a
bit about how to save water. Finally, how to recycle so it is really beneficial to our
environment. OK. If you have any questions, please do not hesitate to interrupt me
anytime during the talk.
