(答案→)now that gravity has changed
解析：【小题1】句意：既然重力改变了，走路也确实需要练一练了，now that 表示“既然，由于”，故填now that gravity has changed
【小题2】look forward to 期望做某事，后接动名词的形式，负债用be in debt来表示一种状态，故填being in debt
【小题3】be hard to do sth 难以做某事，句意：在那个时候如果食物难以找到的话，人们会挨饿，尤其是在寒冷的冬季，故填was hard to find

【小题5】whenever 表示任何时候，作为连词后可接从句whenever you want; whatever 表示无论什么，故填whatever you like ，句意：你可以随时都来，并且吃你想吃的东西。
