　　1.关键句型练习答案

　　A The man said that he was travelling on the eight o'clock train to London at the time the murder was committed. The inspector asked him if he always caught such an early train. The man said that he did because he had to be at work at ten o'clock, and that his employer would confirm that he was there on time. The inspector then asked him if a later train would get him to work on time. The man supposed that it would, but said that he never caught a later train. The inspector asked at what time he had arrived at the station. The man said that he had arrived at the station at ten to eight. He added that he had bought a paper and waited for the train. When the inspector asked him if he had noticed anything unusual, the man said he hadn't. The inspector suggested that he was not telling the truth and that he did not catch the eight o'clock train, but (caught) the eight twenty-five, which would still get him to work on time. The inspector pointed out that on the morning of the murder, the eight o'clock train did not run at all, as it had broken down at Ferngreen station and had been taken off the line.
