Dear Mr.Smith，

I'm writing to thank you for your gracious hospitality last weekend when I was invited to have dinner with your family.

Your delicious meal impressed me a lot.I really enjoyed myself that night.

So would you honor me to invite you to have a travel to China on April？If you come I'll be very glad to show you around my hometown—Beijing where you can visit a lot of interesting places.

I'm sure that you'll have a good time here.Look forward to your reply！

Yours sincerely，

【解析】写这封感谢信时，先感谢对方的热情招待，表示自己那天晚上过得很愉快，并邀请对方能到自己家做客，最后盼望对方回复。写作时注意hospitality“殷勤，好客”和look forward to“期望，盼望”的用法。
