问题     Official health advice that said household chores help keep you active has been proved wrong by the research, which shows that the people who do the most housework are also the most overweight. A study of the physical activity habits of 4,563 adults, carried out by Professor Marie Murphy at the University of Ulster found that women and older people were particularly likely to list "【C1】_____physical activity as a significant proportion of their moderate to【C2】_____physical activity".
    Murphy said: "We found housework was reversely【C3】_____to leanness, which suggests that either people are overestimating the amount of moderate-intensity physical activity they do through housework or are eating too much to【C4】_____for the amount of activity undertaken."
    Kevin Fenton, director of health and wellbeing at Public Health England, suggested the study could【C5】_____evidence that some people thought they were healthier than they actually were.
    "At an individual level there may be a【C6】_____to overestimate the level of ’good behaviour’ we’re doing and this is reflected when people use food diaries, pedometers(计步器)or apps to measure more【C7】_____what they have achieved." he said.
    But he defended everyday tasks as genuinely useful. He added: "From an individual【C8】_____, physical activities such as housework, doing the shopping and walking to collect children from school, can have【C9】_____impacts on physical and mental wellbeing. People who are even more active will often see greater benefits and it is important to recognise that healthy weight is just one of the potential【C10】_____of physical activity."
A)gentle B)perspective C)positive D)causes
E)objectively F)compensate G)practically H)account
I)adjusted J)related K)reinforce L)tendency
M)outcomes N)vigorous O)domestic
【C9】

选项

答案C

解析 该空位于动词have后和名词impacts前,故确定应填形容词。由该段首句可知,本段说一些日常家务是有益处的(useful),故此处的影响应该是积极的、正面的,故填入positive“积极的”,符合文章语义。
