documents: #Person1#: Have you any plan for the weekend, Tom?
  #Person2#: Yeah, Laura. I'm going for a ride around the Qinghai Lake on Saturday, but it depends on the weather.
  #Person1#: According to the forecast, it'll be cloudy the day after tomorrow, good for a ride.
  #Person2#: Great! Do you go riding often?
  #Person1#: Absolutely. I go as much as I can, because we can really get in touch with nature. It would be nice to get out of the city. Do you want any company?
  #Person2#: Sure, but it will be a 30-mile ride. Have you been riding so long before?
  #Person1#: Yeah, I go a lot too. I even saw a bear and some monkeys on my last ride. My friend Mike and I rode more than 30 miles to a very wild part of the national forest.
  #Person2#: Wow! You must have been pretty far away from the city. Shall we invite him to go along?
  #Person1#: Of course. I'll ask him.
  #Person2#: Thanks. We will have a good time this weekend.
