= 1 ﹨ GB3 ① Seeing the teacher entering the room, the students stood up.

=The couple went shopping, leaving their eldest daughter alone at home. (结果）

= If time permits, I will meet you for lunch. (条件)
4) Asking around, I find many people willing to pay slight higher prices for things that are environmentally.
= when I ask around, I find many people willing to pay slight higher prices for things that are environmentally. （时间）
