Lesson88 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 soon get out.
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.

练习感悟：这两天改变了学习的方法，尽量以当天早上的朗读阅读为主，每天的复习课不再强求要求必须像早上一样十分完美地录制完整。要保障主要的精力用在当天早上新课文的学习上面，注意力聚焦，不能浪费其他时间。当然，对于前一天课文的熟悉也是要同步持续地做。每天的用时要控制在1小时以内，加强效率，要事优先。
