Lesson 88 文本  Trapped in a mine Six men have been trapped in a mine for seventeen hours. If they are not brought to the surface soon they may lose their lives. However, rescue operations are proving difficult. If explosives are used, vibrations will cause the roof of the mine to collapse. Rescue workers are therefore drilling a hole on the north side of the mine. They intend to bring the men up in a special capsule. If there had not been a hard layer of rock beneath the soil, they would have completed the job in a few hours. As it is, they have been drilling for sixteen hours and they still have a long way to go. Meanwhile, a microphone, which was lowered into the mine two hours ago, has enabled the men to keep in touch with the closest relatives. Though they are running out of food and drink, the men are cheerful and confident that they will get out soon. They have been told that rescue operations are progressing smoothly. If they knew how difficult it was to drill through the hard rock, they would lose heart.  文本解析 一）词汇学习Word study 1. collapse vi.（1）倒塌：If explosives are used, vibrations will cause the roof of the mine to collapse.如果用炸药爆破，震动会引起矿顶塌落。With no one to repair it, the old church collapsed long ago.由于无人维修，那座老教堂早就倒塌了。 （2）（因精疲力竭等）倒下；（身体等）垮掉：After many years' hard work, my mother's health collapsed.由于多年的辛苦劳动，我母亲的身体垮了。He had run more than forty miles As soon as he was out of danger, he collapsed.他已经跑了四十多英里路了。他刚脱离危险便（累得）倒下了。 2. 与动词run有关的短语run可以与不同的介词或副词搭配产生不同的含义。（1）run out of可表示“用完”、“耗尽”：They are running out of food and drink.他们的食物和饮料都快消耗尽了。He has run out of money.他的钱用光了。 （2）run after表示“追赶”、“追逐”：She ran through a forest after the two thieves.她穿过森林，追赶那两个小偷。Seeing that his sister was annoyed, he ran after her to apologize.当他发现他妹妹/姐姐生气时，他便追上去道歉。 （3）run over的含义之一是“在……驶过/辗过”：The car ran over a snake/his legs.那车辗过一条蛇/他的双腿。The cat was run over by a train.那只猫被火车压死了。 （4）run in的含义之一是“试车”、“试转（发动机等）”：John is running his new car in.约翰正在试他的新车。Run in the engine before you s
