「課文原句」A smile is the universal facial expression — it is intended to put people at ease. (P29)
「名師點撥」at ease是個固定詞組,意思是“處在舒適、自由自在的狀態(tài)下”。本句中put people at ease意為“使人自由自在;不拘束”。如:Her mind was at ease, knowing that the children were safe.
「知識拓展」(1) ease作名詞講時,表示“安逸;安心;不費力;悠閑”。如:He leads a life of ease. (= He leads an easy life.)
