Dear Professor Liu Kai,
I want to thank you for offering me such useful advice during my research. I have completed my article about advertisements, and I’m quite satisfied 58 it. 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
Qian Lili
