网友回答
(答案→)now that gravity has changed
解析：
【小题1】这里应注意动词的时态，因为Walking does need a bit of practice 用的是一般现在时，由于已经改变了重力，所以现在需要大量的练习，故用now that gravity has changed.
【小题2】in debt负债。因为look forward to 中的to 是介词，所以后用动名词，故用being in debt.
【小题3】这里food是从句中的主语，同时又是find 的宾语，故用不定式的主动was hard to find.
【小题4】这里是主语从句应该用whether引导不能用if引导，故用whether life will continue.
【小题5】第一空是让步状语从句whenever you want; 第二空是名词性从句whatever you like.
