问题     The brains of children are affected by family violence in the
same way as combat affects soldiers, according to a study. In both
cases the brain becomes increasing wary of potential threats.【M1】______
Children who suffer abuse or witness domestic violence are known
to be at greater risk of anxiety and depression in late life.【M2】______
    Scientists carried out magnetic resonance imaging brain scans
on 20 London children with an average age of 12 who have been【M3】______
exposed to documented violence at home. All had referred to local【M4】______
social services. While in the scanner, the children were shown
pictures of male or female faces with sad, calm or angry【M5】______
expressions. Their patterns of brain activity were compared with
that of 23 matched children with no history of family violence.【M6】______
The children exposed to violence responded in the distinct way to【M7】______
angry faces, the study found. Their brains showed heightened
activation in two regions associated with threat detection.
    Previous research has shown a similar pattern in the brains of
soldiers exposed to violence combat situations. The scans suggest
both combat veteran soldiers and children who witness violence
tuning their brains to be hyper-aware of environmental danger.【M8】______
    Lead author Dr Eamon McCrory, from UCL’s Division of
Psychology and Language Sciences, said: "We are only now
beginning to understand how child abuse influences function of the【M9】______
brain’s emotional systems. This research is important because it
provides with our first clues as to how regions in the child’s brain【M10】______
may adapt to early experiences of abuse in the home."
【M2】
选项
答案late一later
解析 词汇错误。late life意为“晚年生活”，而此处要表达的意思是“遭受过家庭虐待和目睹了家庭暴力的孩子在日后的生活中更有可能受到焦虑和抑郁的困扰”。later life表示“日后的生活．后来的生活”，故把late改为later。
