Life expectancy與expected lifespan的意思相同!Life expectancy為專業術語,比expected lifespan更常見,若是非正式用法:「how long something usually lives?」 例: The life expectancy of a goldfish is 10 to 15 years. = Goldfish usually live for about 10 to 15 years. (金魚的平均壽命約為10至15 年。) 例:An animal's life expectancy can be quite long. But it often depends on their living conditions. (動物的預期壽命可能很長。 但這通常取決於牠們的生活環境。)
