One of your pen pals will shortly be visiting your city. For some reason, you can not manage to meet him at the airport on time. Write a letter:
1) explaining why you cannot meet him at the airport,
2) asking him to wait for you at the airport, and
3) telling him how to identify you.
You should write with no less than 100 words on Answer Sheet 2. Do not sign your own name at the end of the letter. Use “Li Ming”instead. You do not need to write the address.

Dear Martin,
I am looking forward to your visit. Just think, after all these years of writing to each other, we will finally have the chance to meet! However, I am sorry that I will not be able to meet you at the airport as soon as you arrive.
The reason is that your flight will arrive early in the morning, and the earliest I can get To the airport will be about an hour after you land. Please wait for me in the arrival lounge. You should be able to have breakfast there while you wait.
