wheel和roll在表示推的时候的区别

牛津高阶里是这样分别解释的：wheel。动词[usually +adv。/prep。]通常后加形容词或介词1）move sth with wheels 有轮子的移动a。推的东西是有轮子的。如：She wheeled her bicycle across the road。b。移动的东西是在有轮子的事物里,或在有轮子的事物上。如：The nurse wheeled him along the corridor。（推的是轮椅）c。圆圈式移动 Birds wheeled above us in the sky。roll。动词1)turn over翻过来,翻倒a。向特定的方向翻或移动; 以一个圆的对象做移动,如：The ball rolled down the hill。◆ We watched the waves rolling onto the beach。◆ Tears rolled down her cheeks。◆ [VN] Delivery men were rolling barrels across the yard。b。在同一个地方保持圆的移动,或使事物保持圆圈式的状态。如：a dog rolling in the mud ◆ [VN] He was rolling a pencil between his fingers。◆ Her eyes rolled。c。绕到不同的方向,如：She rolled over to let the sun brown her back。◆ He rolled onto his back。d。在轮子上移动,如：The car began to roll back down the hill。这样看来,我觉得wheel主要是与轮子有关的推,而roll是与圆圈有关,而且是为形成圆圈而做的移动。你感觉呢?
