Lesson 46 Expensive and Uncomfortable
When a plane from London arrived at Sydney airport, workers began to unload a number of wooden boxes which contained clothing. No one could account for the fact that one of the boxes was extremely heavy. It suddenly occured 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 uncomfortable trip, for he had been confined to the wooden box for over eighteen hours. The man was ordered to pay 3500 pounds for the cost of the trip. The normal price of a ticket is 2000 pounds.

练习感悟：
1.任务要早点完成，不能拖，否则精力会受影响，完不成的风险也更高。
2.发现练习过程中一走神效率就会很低，读着读着思维就跑远了。下次开始记录各部分练习花费的时间，也要关注效率。
