问题描述:

And,even if a child experiences the risks of street life firsthand,like by getting shot .
And,even if a child experiences the risks of street life firsthand,like by getting shot or stabbed,this only reinforces the child's desire for more exposure to the learning of street life,to do better next time by listening more closely to delinquent peers and not to the advice of legitimate authorities.
请教里面的like by getting shot or stabbed这一部分:
like是比如的意思,后面直接跟getting shot不是就可以了吗?为何like后面要加上by,不明白by在此是做什么用的?

like by getting shot or stabbed=like experiencing the risks .by getting shot or stabbed
明白了吧.意思是进行了省略吗?原来是这样。。。只是去掉by不是更简单吗?like getting shot or stabed怎么要加by这样写,用一个省略啊?如果不加by,意思就不一样了like getting shot or stabed意思就是 把getting shot...看作 experiencing risks..的一种而本句 like by getting shot or stabed说的是 以什么方式 而experience the risks...的
