237. 我从小就认识他。
[误] I have known him since a child.
[正] I have known him from a child.
. I have known him since his childhood.
注：从过去某一时期到现在为止，英语要用现在完成时态，介词就用 since，但有时不说“迄”（till）也可以说“起”（from）的，即用“from + 普通名词”代替“since + 抽象名词”。但在 from 后也同样可接抽象名词，所以不说 He has been blind since childhood，而说 He has been blind from childhood. 也是一样。
