Lesson 87 文本   A perfect alibi 'At the time the murder was committed, I was travelling on the 8.0 o'clock train to London,' said the man. 'Do you always catch such an early train ?' asked the inspector. 'Of course I do,' answered the man.' I must be at work at 10.0 o'clock. My employer will confirm that I was there on time.' ' Would a later train get you to work on time ?' asked the inspector. ' I suppose it would, but I never catch a later train.' 'At what time did you arrive at the station ?' 'At ten to eight. I bought a paper and waited for the train.' 'And you didn't notice anything unusual ?' ' Of course not.' 'I suggest,' said the inspector, 'that you are not telling the truth. I suggest that you did not catch the 8.0 o'clock train, but that you caught the 8.25 which would still get you to work on time. You see, on the morning of the murder, the 8.0 o'clock train did not run at all. It broke down at Ferngreen station and was taken off the line.' 文本解析 一）词汇学习Word study 1. commit vt.（1）犯（罪），做（错事、坏事等）：A murder was committed at 8 o'clock this morning.今天早上8点钟发生了一起凶杀案。He has never committed any crime before.他以前从来没有犯过罪。 （2）承诺，使承担义务，卷入（经常与反身代词连用）：You should know each other better before committing yourselves to marriage.在缔结婚姻以前，你们应该更好地互相了解。He has committed his friend to taking part in the race.他使他的朋友答应参加比赛。 2. confirm vt.（1）证实，确定：My employer will confirm that I was there on time.我的雇主会证明我是按时到那儿的。His words are confirmed.他的话得到了证实。 （2）巩固，加强：His experiences in that company confirmed his decision to have a factory of his own.他在那家公司的经历坚定了他想自己拥有一个工厂的决心。What he saw and heard that night confirmed his belief that the pub was haunted.那天晚上的所见所闻使他更加坚信那个小酒店有鬼魂出没。 二）课文详注 Further notes on the text 1.
