介词by有多种含义,这里的by可以表示程度和比率,通常指时间、空间和数量等的相差。如:
He missed the train by five minutes.他晚了五分钟没赶上火车。
He is older than me by two years.他比我大两岁。
They were late for the meeting by ten minutes. 他们开会迟到了十分钟。
The car factory increased the output by 10% last year.去年,这家汽车制造厂把产量增加了百分之十。
Our production cost has dropped by one half now. 现在,我们的生产成本已经下降了一半。
