mindmap root((踉跄)) reel usually suggests a turning round and round or a sensation of so turning or being turned, but it may also imply a being thrown off balance: a boxer ~ing from the blow. whirl is often used like reel: their heads ~ing with confusion; but it more frequently implies swiftness or impetuousness of movement: dancers ~ing about the stage. （swift表示动作既快速又轻松rapid and easy，如a swift current/runner湍急的水流/轻快的跑步者） stagger stresses loss of control and uncertainty of movement, typically of a person walking while weak, intoxicated, or heavily burdened but sometimes simply of someone meeting with difficulty or adverse conditions: ~ed by the sheer enormity of the task. totter not only implies weakness or unsteadiness that causes uncertain movement but often also hints at the approach of complete collapse: watched closely as the oligarchy ~ed. （collapse的意思是to fall down, 既可指物也可指人，表示崩塌或摔倒昏倒） 寡头政治
