．Minority youths arrested on violent felony charges in California are more than twice as likely as their white counterparts to be transferred out of the juvenile-justice system and tried as adults, according to a study released last week by the Justice Policy Institute, a research center in San Francisco.

結(jié)構(gòu)分析：這是一個(gè)比較長的簡單句。“more than twice as likely as their white counterparts”是一種表示倍數(shù)的表達(dá)方式；“to be transferred out of the juvenile-justice system and tried as adults”不定式短語來修飾white counterparts; “according to a study released last week by the Justice Policy Institute”做狀語；“a research center in San Francisco”是“the Justice Policy Institute”的同位語。
