愚公,NewVoice,小薇,Newton等同學(若有落下的同學不好意思啊,比較倉促)都用對了。語法功底深厚。
原文是對過去時的虛擬:要是我在年輕時養成了這種習慣,就可以避免時間上驚人的浪費。
愚公: If I had cultivated this habit while I were young, I would have not waisted a staggering amount of time.
小薇:If I had had this good habit when I was young, I would have avoided huge waste of time.
NewVoice: If I had acquired such habit in my youth, I would have avoided wasting a great amount of my time.
Newton:It would have avoided an astonishing waste of time if I had been accustomed to such habit when I was young.
