Lesson77 A successful operation
The mummy of an Egyptian woman who died in 800 B.C. has just had an operation. The mummy is that of Shepenmut who was once a singer in the Temple of Thebes. As there were strange marks on the X-ray plates taken of the mummy, doctors have been trying to find out whether the woman died of a rare disease. The only way to do this was to operate. The operation, which lasted for over four hours, proved to be very difficult because of the hard resin which covered the skin. The doctors removed a section of the mummy and sent it to a laboratory. They also found something which the X-ray plates did not show: a small wax figure of the god Duamutef. This god which has the head of a cow was normally placed inside a mummy. The doctors have not yet decided how the woman died. They feared that the mummy would fall to pieces when they cut it open, but fortunately this has not happened. The mummy successfully survived the operation.

练习感悟：
1.一到周末就容易没规律差点忘记写总结
2.这篇材料的p、h音比较多，而且相隔不远，读句子的时候总觉得气息浮在上面，清辅音嘛，不如浊辅音那么用力，然而不用力发音也会不清楚，这就要用到腹部的力量了，像小狗一样喘气来感受腹部的力量。
