knock off和 knock over 有什么不同?

当knock off和knock over同时在表示“撞倒”意思的时候,knock over一般就是指撞倒（+ed被动）,比如说A boy was knocked over by a passing car but was fortunately unhurt。而knock off则指从某个地方（被）撞倒,如A boy was knocked off his bike by a passing car but was fortunately unhurt。knock off:knock off打翻;撞倒 撞倒;打掉 The little girl knocked the glass off by accident。小女孩不小心碰落了玻璃杯。减去 They knocked off five dollars from the price。他们把价格降低了五美元。停止;歇工 Let's knock off now。咱们现在歇一会儿吧。knock over打翻;撞倒 He knocked a glass over。他把玻璃杯打翻了。使惊奇 She was knocked over by the news。她被那消息惊呆了。消除 We have knocked over every difficulty。我们已排除种种困☞希望我的回答对你有所帮助,如果还有疑问,可以在百度HI给我留言☜
