问题     Young girls at high risk for depression appear to have a malfunctioning reward system in their brains, a new study suggests. The finding comes from research that【1】a high-risk group of 13 girls, aged 10 to 14, who were not depressed but had mothers who【2】recurrent depression and a low-risk group of 13 girls with no【3】or family history of depression. Both groups were given MRI brain【4】while completing a task that could【5】either reward or punishment.
【6】with girls in the low-risk group, those in the high-risk group had【7】neural responses during both anticipation and receipt of the reward.【8】, the high-risk girls showed no【9】in an area of the brain called the dorsal anterior cingulated cortex (背侧前扣带皮质), believed to play a role in【10】past experiences to assist learning.
    The high-risk girls did have greater activation of this brain area【11】receiving punishment, compared with the other girls. The researchers said that this suggests that high-risk girls have easier time【12】information about loss and punishment than information about reward and pleasure.
    "Considered together with reduced activation in the striatal (纹状体的) areas commonly observed【13】reward, it seems that the reward-processing system is critically【14】in daughters who are at elevated risk for depression,【15】they have not yet experienced a depressive【16】," wrote Ian H. Gotlib, of Stanford University, and his colleagues. "【17】, longitudinal studies are needed to determine whether the anomalous activations【18】in this study during the processing of【19】and losses are associated with the【20】onset of depression," they concluded. The study was published in the April of the Archives of General Psychiatry.
选项 A、Made
B、Regarded
C、Insisted
D、Compared
答案D
解析 根据上一题对第一段末句的分析可知，本句是将两组实验结果进行对比，而且所填词要与with搭配。[D] Compared与with搭配，意为“和某物作比较”，符合题意。[A] Made with用法举例：what do we make with flour?我们用面粉做些什么?[B] Regarded with用法举例：They regarded those homeless children with great sympathy．他们非常同情那些无家可归的孩子。[C] Insisted通常不与with搭配，而与on搭配构成词组insist on，用法举例：I insist on an immediate answer．我坚持要立即给予答复。
