解析：
【小题1】考查现在分词做宾语补足语：hear +宾语+doing，听到…正在做…,填approaching
【小题2】考查时态;时间是that day用lead的过去时 led
【小题3】考查时态：时间是 in the past several months.用现在完成时或现在完成进行时：has been rising / has risen
【小题4】avoid后面接动名词做宾语，children and old people,和affect是被动关系，用动名词的被动 being affected
【小题5】考查过去分词做宾语补足语：keep+宾语+过去分词，us和inform是被动关系，用informed
【小题6】考查时态;时间是at 11 o’clock last night.用过去将来时 was surfing
【小题7】考查时态语态：weigh做重达…的时候，不能用被动式，用主动，而且主语是The box ，定语从句的谓语用单数weighs
【小题8】考查不定式做目的状语：To reduce，为了减少被烧伤的危险，你最好避开火。
【小题9】考查时态：时间是By the time 谓语是过去完成时had taken
