1.to get on : (to enter, board)
    【說明：】to get on(搭乘，上車) 動詞get的用法很多，常常在后面接用各種不同的介系詞或副詞而形成意義不同的習語。這里的on是介系詞，后面的bus和subway用作它的受詞。如果on作副詞用，則有進步，相處甚好，與年事已長的意思。
    【例：】
    (1) I always get on the bus at 34th Street.
    我總是在３４街搭乘公共汽車。
    (2) William gets on the subway at the same station every morning.
    威廉每天早晨在同一車站搭乘地下火車。
    2.to get off : (to leave, descend from)
    說明：】to get off (下車)與上面的get on相反。Get off也有好些其它的意義，如寄出，離開等。下車也可以用alight from或get out of a carriage或motor car, 不過下電車或公共汽車多用get off .
    【例：】
    (1) Helen got off the bus at 42nd Street.
    海倫在42街下公共汽車。
    (2) At what station do you usually get off the subway?
    你通常在那一站下地下火車？
    3.to put on: (to place on oneself-said particularly of clothes)
    【說明：】
    to put on (穿，戴)特別指穿衣服、穿鞋、戴帽、戴眼鏡也用這個成語。英文中還有wear和dress二字也是穿的意思。可是wear是繼續(xù)的動作，表示穿著的狀態(tài)，而put on是一時的動作。下面兩個句子都是錯的：
    I shall wear my overcoat before I go out (應用put on). In such cold weather I put on my overcoat all day （應用wear）.dress的意思是
    ①put clothes on后面的受詞一定是人，如dress a child, dress oneself, be dressed in white,
    ②put on clothes, vk Get up and dress quickly. （快點起來穿好衣服。）
    【例：】
    (1) Mary put on her hat and left the room.
    瑪麗戴上她的帽子就離開這屋子。
    (2) Why is John putting on his hat and coat?
    約翰為什么穿衣戴帽呢？
