19、pable of doing each other harm, there is a 【B13】 . for the losing animal to show the winning animal that he wishes to submit. When he shows this, the 【B14】 normally stops fighting. Animals (especially birds), which can easily escape from conflict seem to have no 【B15】 against killing, and equally no

38、 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

39、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 womans custom every morning to throw her dog two biscuits

40、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.

41、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 betwee

42、n 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

43、 expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worseeven dangerous. （分数：1.00）(1).In his study Professor Smith asked the subjects _（分数：0.20）A.to keep truck of people who tend to forget thingsB.to report their emba
