问题      Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absentminded actions for a fortnight. When he came to analyze their embarrassing lapses in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. Nor did the lapses appear to be entirely random.
     One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People program themselves to do certain activities regularly. It was the woman’s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the program." About one in twenty of the incidents the volunteers reported were these "program assembly failures."
     Altogether the volunteers logged 433 unintentional actions that they found themselves doing--an average of twelve each. There appear to be peak periods in the day when we are at our zaniest, These are two hours some time between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. "Among men the peak seems to be when a changeover in brain ’programs’ occurs, as for instance between going to and from work." Women on average reported slightly more lapses--12.5 compared with 10.9 for men--probably because they were more reliable reporters.
     A startling finding of the research is that the absent-minded activity is a hazard of doing things in which we are skilled. Normally, you would expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worse——even dangerous.  
It can be concluded from the passage that______
选项 A、people should avoid doing important things during peak periods of lapses
B、hazards can be avoided when people do things they are good at
C、people should be careful when programming their actions
D、lapses cannot always be attributed to lack of concentration
答案D
解析 根据文章最后一句"But trying to avoid silly slips by concentrating more could make things a lot worse—even dangerous．”，即可推理出正确答案为D 。另外，如果读者能够认识到，在这篇文章中，作者讨论的是这样一个事实：“人们在从事自己擅长的常规事情往往会心不在焉”，由此就可以将其他三个选项排除。
