Walking actually burns as many calories as running the same distance ----if done in the correct manner and at a reasonable pace.
1）请问as many calories as running the same 是什么结构，什么意思，怎么理解？
2）if 后面怎么能跟done 呢？这是分词吗？是什么作用？

句子应该这么分析
as many calories as running 跑步和走路消耗一样多的热量
the same distance 同样的距离
done是指 walking and running is done in the correct manner....

running the same distance ,跑一样的距离。
行走实际上能消耗“跑一样的距离”所消耗的热量——

后面的if done是省略：完整的是：if it is done in the ……

1）as+形容词（原形）+as+事物+（the same）
如as thin as a rail

2)有一些语言无法用语法解释，这很地道。
