Before we get started on the presentation, allow me to briefly introduce myself.

I'm here from express.com to discuss how our services work and how they can benefit your company.

By the end of this presentation, you'll understand why home security systems matter

Please allow me to end my presentation by summarizing the benefits of our service.

Why don't we take a break for a few minutes？

I think I'll close here. Are there any questions？

Would you say that again, please？

I could probably guess, but honestly I don't know the exact figure.

I'm afraid I don't have that information. But if you leave your email address with me, I'll get back to you on that.
