短文改错

Dear Peter,

I’m very much delighted that you are coming here for the holiday. But I’ll be able to meet you at the airport as

we planned, as I will be host a speech contest at that time. I’m terribly sorry about that. But I had asked my best friend to go to an airport at 6:00 on Saturday afternoon to meet you. He will be the airport while you arrive, hold a board with your name on it. Then he will take you by taxi to the hotel that we have booked a room for you. I will call you late. Wish you a pleasant journey. And I’m looking forward seeing you soon.

Yours, truly,

LiHua
