【正确答案】[译文]但是，罪犯们很快认识到电脑的真正价值在于芯片(集成电路板)，而芯片非常易于随身携带，又很难识别，所以，即使(盗贼)被抓获，警察也难以将其定为盗窃。

【答案解析】[要点]这是一个并列主从复合句，两个句子由so连接。句架是...the criminal fraternity...came to realize that...value in the computers is in the chip which...，so even when caught the police have trouble...。在前面句子里that引导的从句，作realize的宾语；后面句子里when caught是过去分词作状语，when caught即when the thief was caught；proving是现在分词，修饰trouble。句中criminal fraternity指盗贼们。
