如果你能听到脚步声，如果你的脚很用力地着地…如果你像我们在实验室说的发出砰砰的重击声，那么你正是在笨拙地跑步。

If you can hear your feet, if your feet are landing really hard... if you are thumping as we call it in my lab, then you're running poorly.

树荫遮蔽下，一只珍珠鸟被圈了起来，两头母牛在Sawadogo的脚边打瞌睡。 在这个寂静的傍晚，我们只能听到几只山羊咩咩的叫声。

Two cows dozed at his feet; bleats of goats floated through the still late-afternoon air.
