解析：
【小题1】 natural 本句的natural和后面的safe一样都是形容词。
【小题2】has increased 后面有时间状语by now，与现在完成时连用。
【小题3】that/which 本题是定语从句，which/that指代先行词在句中做动词share的宾语。
【小题4】If/When 本句可以作为时间状语或者条件状语，用if/when连用。
【小题5】it 本句中的it是形式主语，真正的主语是后面的不定式。
【小题6】your 根据第4空后的You可知这里使用your来修饰garden.
【小题7】to make 本句使用不定式在句中做表语，表示具体的动作。
【小题8】a 固定搭配a kond of…一种…
【小题9】for 介词for和一段时间连用，表示持续了一段时间。
【小题10】 healthier 本句中使用比较级的形式与后面的better呼应。
