In other words, we have to go beyond the proximate cause and probe further and further.

换句话说，我们必须超越事物的近因，进一步讨论其起因。

The sample groups in both studies were small, and in the overwhelming number of cases of coronavirus death, heart failure is not the proximate cause.

两项研究的样本组都很小，而且在绝大多数冠状病毒死亡病例中，心力衰竭不是直接原因。

When we put all these pieces together, this ultimate explanation for nearsightedness -- that environmental and behavioral change impact the way we use our eyes -- helps us better understand the proximate cause.

当我们将所有这些部分放在一起时，这种对近视的最终解释——环境和行为的改变会影响我们使用眼睛的方式——有助于我们更好地理解近因。
