Wrong focus

林鄭月娥上星期訪問英華小學，但少有人討論林鄭的訪問內容，焦點大都放在美女小學老師，完全錯重點（wrong focus）……

名詞focus解「焦點、重點」，即是注意力或興趣的中心--centre of attention or interest。例句︰This ancient Chinese painting will become the focus of interest at the auction.（這幅中國古代繪畫將成為拍賣會的焦點。）This argument has a wrong focus and fails to address necessary issues.（這個論點的焦點錯誤，無法解決必要的問題。）His mother was sick and had become the focus of all his energies.（他的母親病了，他把全部精神都放在她身上。）

名詞focus還可以指「物理學的焦點、聚光點」。例如，set the focus of the camera lens（設定相機鏡頭的焦點）；Many of the photos were totally out of focus.（許多照片完全不對焦。）

Focus可以用作動詞，解「集中、調節焦距」。例句︰We need to provide a quiet environment to allow children to focus on their homework and finish it.（我們需要提供安靜的環境，讓孩子專注於他們的功課並完成它。）How can I focus the lens on a close object？（如何將鏡頭對準近的物件？）
