justify後接doing還是todo

justify後加doing。

因為它是（及物動詞，後接名詞、代詞或動名詞）“表明或證明（某人/某事）是正當的、有理的或公正的”：

Such action can be justified on the grounds of greater efficiency.以提高功效為依據可以證明採取這種措施是正確的。

You shouldn't attempt to justify yourself.你不應想方設法證明自己有理。

You can't justify neglecting your wife and children.你不關心妻子兒女是説不過去的。
