Dear Paul,

I'm happy to help you with your assignment. First, choose a prominent ancient Chinese scientist, like Zhang Heng or Shen Kuo, and gather information from reputable sources such as books or academic articles. Create an outline highlighting their major contributions and impacts on science. Practice your presentation several times to ensure you're confident and clear. Additionally, consider engaging your audience with interesting anecdotes or visuals. Lastly, anticipate potential questions and prepare answers. Good luck with your report!

Best regards, Li Ming
