问题 ______come out of the building, my first thought was to call the fire department.
选项 A、On seeing the smoke
B、When I saw the smoke
C、Having seen the smoke
D、As soon as the smoke was seen
答案B
解析 此题考点为状语从句。由于主句的主语是“thought”，不能是A和C的逻辑主语，应排除 A和C；D项的结构有错误(“seen”之后的不定式必须有“to”)；所以选B。本句的意思是：当我看见大楼冒烟了，我首先想到的是去报火警。
