题目

however放主句和从句之间,被逗号隔开,到底修饰的是主句呢,还是从句呢?
An arrest made by a Midville police officer is provisional until the officer has taken the suspect to the police station and the watch commander has officially approved the arrest.Such approval is denied if the commander judges that the evidence on which the provisional arrest is based is insufficient.A government efficiency expert has observed that almost all provisional arrests meet the standards for adequacy of evidence that the watch commanders enforce.The expert has therefore recommended that because the officers’ time spent obtaining approval is largely wasted,the watch commander’s approval no longer be required.This recommendation should be rejected as dangerous,however,since there is no assurance that the watch commanders’ standards will continue to be observed once approval is longer required.
最后一句话,This recommendation should be...,however,我认为修饰的应该是前一句话.但这样一放会不会,就搞不清他到底是在哪转折.中文直译的话,我会认为他是在说：‘’ 但是,since.required.

答案

however是个副词,表示转折.然而……
这里放在句首也可以的：
However,this recommendation should be rejected as dangerous since there is no assurance that the watch commanders’ standards will continue to be observed once approval is longer required.
又如:
He said that he would come.However,he still didn't appear.
