单选题
1.【A1】
【正确答案】
C
【答案解析】考查动词短语辨析。前面句子…focus either on the individual or on society as the major contributing influence已经点明许多研究青少年犯罪的理论强调个人或者强调社会作为导致犯罪的主要原因。因此,正确答案为C.centering,centering on“集中于”。acting on“作用于”;relying on“依赖于”;commenting on“评论”,均不符合题意。

2.【A2】
【正确答案】
D
【答案解析】考查逻辑关系。“…that children engage in criminal behavior______they were not sufficiently penalized for previous misdeeds…”意思是:孩子从事犯罪活动______以前的恶行没有得到应有的惩罚。不难发现,前后两个句子是因果关系。因此,正确答案为D.because。before“在…之前”:unless“除非”;until“直到…”,均不符合题意。
【答案解析】考查动词辨析。本句中的“that”指代“changes in the economy”,句子大意为:经济变革青少年工作机会减少和失业率上升。从中可以推出句内是因果关系,因此只有lead to“导致”符合句意,故选B。point to“指向”;come to“达到,苏醒”;amount to“合计,总计”,均不符合题意。
【答案解析】考查连词辨析。从“children are likely to have less supervision at home was common in the traditional family”不难发现,句子中体现了比较级,因此,正确答案为A.than。即孩子受到的家庭监督可能比过去的传统家庭少。that、which、as一般引导从句,均排除。
