参考范文：

Dear Eric,

I’m glad to hear that you’re interested in the cybersecurity lecture which we had last week.

It took place on Friday afternoon, and the theme was “Protecting Yourself in the Digital World.” The expert discussed various topics, such as how to create strong passwords, recognize phishing scams, and secure personal information online. He also emphasized the importance of updating software regularly to avoid vulnerabilities. I found the lecture very informative. I learned how to better protect my online accounts and became more aware of potential cyber threats. It made me realize how crucial it is to stay vigilant in the digital age.

I hope you find this helpful too!

Best regards,

Li Hua
