老话说:一分耕耘一分收获。这是常理,但是细究起来,它的意思其实是说,没有耕耘就没有收获,而不是说你付出了劳动就一定有收获。天有不测风云,假如你不幸遇到了严重的旱涝天灾,那你付出再多的辛劳,也不会有好收成。所以有些事情真的是要“靠天吃饭”的。这个“天”可能是天气,也可能是运气,也可能是其它复杂的原因。总之,现实就是这样残酷。你不付出、不努力就一定没有收获; Old saying goes: a bit hard to harvest. This is a commonsense. However, when we study it carefully, it actually means that there is no gain without hard work, not that you have to reap the benefits of labor. There are unexpected events, if you unfortunately encountered serious droughts and natural disasters, then you have to pay more hard work, there will be no good harvest. So some things really want to “rely on the weather to eat ”. This “sky ” may be the weather, it may be luck, it may be other complex reasons. In short, the reality is that cruel. You do not pay, no effort will not be harvested;
