我把他看作透明 英文是不是I look him as transparent??

I look him as if he is transparent. 中间要加这些才能流利

I can see his through.

"see through"经常用来指“能把某人看穿”，不管对方的用意，诡计，还是好心，是个中性词。如果你在这里想表达的是这个方面的意思，我想see through更合适。

I regard as transparently him

我想应该是：I ignored him (as if he was air).

look不能这么用的
He is transparent to me.可能更好些

yes
