Since then, they have been trying to find out how the fire began. Forest fire are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however, a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16,000volt power line. In this way, he was able to solve the mystery. The explanation was simple but very unusual. A bird had snatched up the snake from the ground and then dropped it on to the wires. The snake then wound itself round the wires. When it did so, it sent sparks down to the ground and these immediately started a fire. Lesson54 Sticky fingers 粘糊的手指 After breakfast, I sent the children to school and then I went to market. It was still early when I returned home. The children were at school, my husband was at work and the house was quiet. So I decided to make some tarts for tea. In a short time I was busy mixing butter and flour and my hands were soon covered with sticky pastry. At exactly that moment, the telephone rang. Nothing could have been more annoying. I picked up the receiver between two sticky fingers and was dismayed when I recognized the voice of Mrs Bates. It took me ten minutes to persuade her to ring back later. At last I hung up the receiver. What a mess! There was pastry on my fingers, on the telephone, and on the doorknobs. I had no sooner got back to the kitchen than the doorbe ll rang loud enough to wake the dead. This time it was the postman and he wanted me to sign for a registered letter !

No one could account for the fact that one of the boxes was extremely heavy. It suddenly occurred to one of the workers to open up the box. He was astonished at what he found. A man was lying in the box on top of a pile of woollen goods. He was so surprised at being discovered that he did not even try to run away. After he was arrested, the man admitted hiding in the box before the plane left London. He had had a long and unfortable trip, for he had been confined to the wooden box for over ten hours.
