答案解析部分
1．Dear friends,We've just landed on Mars. We've already discovered a lot of creatures on the planet. They are happy and friendly. As their language is quite different from ours, they haven't sent a message to us. To know them better, we've tried to communicate with them and have taught them how to send a message to the Earth. What's more, we learned about their advanced technologies and tried studying them ourselves. They haven't visited us yet because they aren't sure how to make it. We've told them something about our planet and have invited them to visit us one day.
I'm looking forward to hearing from you soon.
Yours,
Frank
