After the tsunami in the Indian Ocean, the entire world has shown great concern and sympathy for the affected countries, and many countries and international organizations have helped them by providing rescue funds, supplies, etc. For a patient, blood transfusion is needed, but oxygen transfusion is needed, but The patient's healthy life ultimately depends on his own vitality and his own function. This passage mainly supports the view that:. ['An important reason why the affected countries did not receive immediate assistance after the tsunami is that many countries and international organizations did not provide adequate relief to them.', 'So long as the countries and international organizations of the world can continue their assistance, the socio-economic situation of the affected countries will be restored.', 'After receiving various aids, the socio-economic recovery and development of the affected countries ultimately depend on their own efforts.', "The rescue of critical patients requires blood transfusion and oxygen transfusion, but the recovery of patients' health depends mainly on their own immune capabilities."]
