Good afternoon, ladies and gentleman. First of all, let me thank you all for
coming here today. As most of you have known I’m Yolanda, your
classmate. My subject of my presentation is how to prevent globe
warming. It is very important to you, because it is reported that if globe
warming is continually getting worse. Globe will ruin in the next century.
Therefore, I would like to divide my presentation into three parts.
First, what cause for global warming.
Second, the effect for global warming
Third, what can we do to prevent globe warming?
The whole presentation will take about 10 minutes.
Don’t worried about taking notes. I’ve also prepare a handout with
key point on it to give you after my speech. If you have any question,
you are welcome to ask at anytime. What cause for global warming?
The largest contributing is the burning of fossil fuels leading to the
emission of carbon dioxide.
