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."
【M8】
选项
答案tuning一tune
解析 语法错误。此句中suggest后接一个省略that的宾语从句，该从句的主语soldiers andchildren后又接了一个who引导的定语从句，此处tuning不是现在分词作伴随状语。而应该作宾语从句的谓语，表示“战争老兵和孩子们将他们的大脑适应于……。”故应改成tune。
