问题描述：

1George even wore the ring when he was gardening—and that was how he came to lose it.
我想问came to lose it的came to何解
how he came to lose it 与how he lost it 有什么区别

这里的coming in to又何解
答
come away (from sth.)与某物脱离,从……脱落；
【例】The newspaper has started to come away from the wall.
报纸已经开始从墙上脱落.
所以,come away from the window,从窗户上脱离（或者是之类的意思）；
come 在这里应该是表示变成某种状态,如My shoe laces have come undone.(我鞋带松了).
