It has just been published on our school website. I never knew that advertisements were so interesting! The information I found will really help me to educate others. I hope that after they    59    my article, my schoolmates will understand that PSAs    60   intended to educate us about public welfare issues, and    61    commercial ads are meant to promote products or services. Before our talk, I did not think very much about how an advertiser might be trying to trick customers    62   buying a   63   or a service. Now I think I will be much smarter about what things to buy. Even if there are lots of exciting images and persuasive language. I will remember to think about the things I buy. I will also pay a    64    more attention to the nationwide public service ad campaigns because now I know how helpful they can be. I will encourage my friends    65    pay attention to them as well.

Thank you again for helping me find so much useful information!

Yours faithfully
