「课文原句」A smile is the universal facial expression — it is intended to put people at ease. (P29)
「名师点拨」at ease是个固定词组,意思是“处在舒适、自由自在的状态下”。本句中put people at ease意为“使人自由自在;不拘束”。如:Her mind was at ease, knowing that the children were safe.
「知识拓展」(1) ease作名词讲时,表示“安逸;安心;不费力;悠闲”。如:He leads a life of ease. (= He leads an easy life.)
