同学你好~
Doctors operated a Egyptian woman of the mummy who died in 800B.C.
冠词错误：a Egyptian → an Egyptian（元音开头用an）
逻辑混乱：operated a woman of the mummy 表述不清（木乃伊是woman的遗体，非所属关系）
修正：
Doctors operated on the mummy of an Egyptian woman who died in 800 B.C.

They wanted to find out whether the woman died of a rare disease.
时态问题：died of → had died of（因主句是过去时，从句需用过去完成时表更早发生）
修正：
They wanted to find out whether she had died of a rare disease.

After removing a section from the mummy and sent it to a laboratory.
问题：
句子不完整：After引导的介词短语不能独立成句
修正：
After removing a section from the mummy, they sent it to a laboratory.

During the operation, unexpectedly found that the god figure was placed inside the mummy.
缺主语：unexpectedly found前需加they
修正：
During the operation, they unexpectedly found a god figure inside the mummy.

Though Doctors were afraid that the mummy would fall to the pieces, the mummy survived the operation yet.
大小写错误：Doctors → doctors（非句首/专有名词不大写）
介词错误：fall to the pieces → fall to pieces（固定搭配无the）
yet冗余：yet用于否定句，此处删去
修正：
Though doctors feared the mummy would fall to pieces, it survived the operation.

祝同学学习进步~
