Lesson91 Three men in a basket
A pilot noticed a balloon which seemed to be making for a Royal Air Force Station nearby. He informed the station at once, but no one there was able to explain the mystery. The officer in the control tower was very angry when he heard the news, because balloons can be a great danger to aircraft. He said that someone might be spying on the station and the pilot was ordered to keep track of the strange object. The pilot managed to circle the balloon for some time. He could make out three men in a basket under it and one of them was holding a pair of binoculars. When the balloon was over the station, the pilot saw one of the men taking photographs. Soon afterwards, the balloon began to descend and it landed near an airfield. The police were called in, but they could not arrest anyone, for the basket contained two Members of Parliament and the Commanding Officer of the station! As the Commanding Officer explained later, one half of the station did not know what the other half was doing!

练习感悟：
昨天上了词汇课，所以就没有学音标，而且因为有任务接档，效率很高呀，哈哈哈哈~新概念第二册快学完了，很有成就感，另外在之前的总结里我给自己挖了不少坑，一个都没填呢……自从开始学新概念，在电脑面前坐的时间更长了，而且姿势不正确，我觉得这算是我腰疼的一个诱因，之前一直都是这样，只不过最近是连续的损伤才会爆发出来，而且这段时间的运动量也很少，好伤心啊啊啊啊啊~身体可是革命的本钱啊啊啊啊！昨天的复盘居然忘记发了，因为用了苹果电脑实在不会用，而且还没有中文输入法……
