Dear Paul,
    I'm LiMing. I'm writing to share my viewpoint towards preparing for an oral report on an ancient Chinese scientist.
    In my opinion, it's advisable for you to take te following options. First of all, you can search for the information of scientists who had th same major as you.Second, practise speaking out loud so that you won't be nervous on your reporting day. Last but not least,you may call for help from your Chinese teacher, maybe she can give you more suggestions.
    I do hope my suggestions can help you deal with your oral presentation. I'm looking forward to your early reply!
Yours,
LiMing.
