一个英语句子,找一下语法错误Moreover,on a long-term level saving

on a long-term level表示在长远水平上改为in the long term 好些.saving money作主语的话是单数呀改为 saving money has led us to learnand so such another benefit as becoming a shrewd person改为and another benefit is becoming ashewd person such as that 改为 such as a relationship that is between a predator and its natural prey,======以下答案可供参考======供参考答案1:saving memory作主语，后面的谓语用三单式has供参考答案2:去掉on哈，有on的话就没有主语了

回答的不错
