We have never seen eye to eye on this matter. (我們對此事的意見從來就沒有一致過) (正)
We have never seen eyeball to eyeball on this matter. (誤)
解說:see eye to eye (with someone) 意為“(與某人) 看法完全一致”;eyeball to eyeball 意為“面對面 (face to face)。(尤指) 兩名選手、兩支球隊、兩支敵對軍隊等即將開打、廝殺而怒目相向、對峙”,如 In the playoffs we go eyeball to eyeball with the Tigers. (在季后賽中,我們將對抗老虎隊);We are eyeball to eyeball with the enemy. (我們正與敵軍對峙中)。英文并無 see eyeball to eyeball 這樣的慣用語。
