(1)to get on (2)to get off (3)to put on (4)to take off (5)to call up
(6)to turn on (7)to turn off (8)right away (9)to pick up (10)at once
1. to get on : (to enter, board)
【說(shuō)明：】to get on(搭乘，上車(chē)) 動(dòng)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(xí)語(yǔ)。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(jìn)步，相處甚好，與年事已長(zhǎng)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(chē)。
(2) William gets on the subway at the same station every morning.
威廉每天早晨在同一車(chē)站搭乘地下火車(chē)。
2.to get off : (to leave, descend from)
【說(shuō)明：】to get off (下車(chē))與上面的get on相反。Get off也有好些其它的意義，如寄出，離開(kāi)等。下車(chē)也可以用alight from或get out of a carriage或motor car, 不過(guò)下電車(chē)或公共汽車(chē)多用get off .
【例：】(1) Helen got off the bus at 42nd Street.

【說(shuō)明：】 to put on (穿，戴)特別指穿衣服、穿鞋、戴帽、戴眼鏡也用這個(gè)成語(yǔ)。英文中還有wear和dress二字也是穿的意思�？墒莣ear是繼續(xù)的動(dòng)作，表示穿著的狀態(tài)，而put on是一時(shí)的動(dòng)作。下面兩個(gè)句子都是錯(cuò)的：
I shall wear my overcoat before I go out (應(yīng)用put on). In such cold weather I put on my overcoat all day (應(yīng)用wear).dress后面的受詞一定是人，如dress a child, dress oneself, be dressed in white, Get up and dress quickly. (快點(diǎn)起來(lái)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(kāi)這屋子。
(2) Why is John putting on his hat and coat?
約翰為什么穿衣戴帽呢?
4.to take off : (to remove-said also of clothes)
中學(xué)英語(yǔ) 常用短語(yǔ)精解
