Mrs. Jones was very fond of singing. She had a good voice, except that some of her high notes tended to sound like a gate which someone had forgotten to oil. Mrs. Jones was very conscious(知道的) of this weakness, and took every opportunity she could find to practise these high notes. As she lived in a small house, where she could not practise without disturbing (干扰) the rest of the family, she usually went for long walks along the country roads whenever she had time, and practised her high notes there. Whenever she heard a car or a person coming along the road, she stopped and waited until she could no longer be heard before she started practising again, because she was a shy person, and because she was sensitive (敏感的) about those high notes.

　　One afternoon, however, a fast, open car came up behind her so silently and so fast that she did not hear it until it was only a few yards from her. She was singing some of her highest and most difficult notes at the time, and as the car passed her, she saw an anxious expression suddenly come over its driver's face. He put his brakes on violently, and as soon as the car stopped, jumped out and began to examine all his tyres carefully.

　　Mrs. Jones did not dare to tell him what the noise he had heard had really been, so he got back into his car and drove off as puzzled as he had been when he stopped.
