The mind and eye need exercise as much as do the legs. do用法？

句子中
The mind and eye兩樣西為主要說明"need exercise",
作者同時想平衡地說
The legs都一樣需要"need exercise"這動詞子句，但是寫作不想/不應重覆地這樣寫多一次，因此"as much as"同樣地表達的"動作"便用動詞增強語氣時的寫法do need exercise省略了"need exercise"。

因此句子便成為由以下的句子簡化
The mind and eye need exercise as much as the legs do need exercise.
當省略"need exercise"時便把動詞轉為強調so do NOUN的格式變為：
The mind and eye need exercise as much as do the legs.

The mind and eye need exercise as much as do the legs.
思想和眼睛儘可能需要多做鍛煉，雙腿亦然。

另例：My father loves me as much as my mother *does.
我父親和我母親*一樣*愛我。

註：在這𥚃“do"的用法解作: 亦然、同樣、一樣
