请问大家
Coinciding with changing judicial requirements has been the staggeringincrease
crime rates in the United States. This factor alone would probably have suffi
ced to account for the increased utilization of crime laboratory services by p
olice agencies ""were it not for the fact that only a small percentage of poli
ce investigations generate evidence requiring scientific examination.""
里的were it not for意思是 if there were not的意思吧?? 假设语态
那么这整句的意思是指
""要不是事实是只有少部份警察调查的证据需要科学验证，这单一因素可能就足以说明警
察机构在犯罪实验室的使用率上是增加的""
这样吗?? 因为跟上一段意思有点兜不上
所以不是很确定
请各位帮帮忙，感谢!!! :)
