The fragility of life
Each seemingly powerful human life <em>[clearer emphasis]</em>, seemingly powerful <em>[stylistically better for your sentence to move here on its own, demarcated with commas]</em>, yet in the face of illness. L like an ant ants, is fragile and cannot withstand a single blow.
in my memory From what I can remember <em>[stylistically better]</em>, it was the first time I saw when I first saw <em>[stylistically better]</em> a close relative lying on a single hospital bed stand for a moment to sit and repeatly without sleep <em>[I don't understand what is happening here]</em>.The doctor also is helpless.This is the pancreatic cancer patient. Crying is useless. We can only pray to for God's mercy <em>[accepted expressions are "pray to God", "pray for mercy"]</em> to ease the pain of the patient.
