现年30岁的邬先生在某高校任职，每月税后收入为9000元。邬太太今年27岁，在一家外资银行任职，每月税后收入为5500元。他们有一个宝贝女儿，今年4岁，正在上幼儿园。邬先生夫妇刚刚购买了一套价值60万元的住房，贷款总额为40万元，贷款利率5.5%，20年期，等额本息摊还，下个月开始还款。由于邬先生认为投资股票的风险比较高，所以在银行的存款有10万元，债券基金5万元。邬先生家里常备有3000元的现金。投资报酬率年均4%。
除了每月需要偿还的房贷以外，邬先生一家的生活及工作开支保持在每月平均9500元。由于邬先生夫妇所在单位为他们提供了必要的社会保障，因此他们尚未购买商业保险。
考虑到以后子女教育是一项重要的支出，邬先生决定从现在就采取定期定额的方式为孩子储备教育金。

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.
