正确的表达是: for no reason. 一起来看两个例句: I know Alisa very well, she never cancels for no reason. 我很了解艾丽莎,她从来不会无缘无故取消约会。 Animals don't attack people for no reason. 动物是不会无故攻击人类的。 在美剧《摩登家庭》中,Claire要竞选议员,但是选民都说她脾气暴躁,接着有了下边的对话: Claire: I am angry, at that poll. Alex: I think it's the yelling. I would tone down the yelling. Claire: Honey, I don't yell for no reason. -我现在生气都是这民意调查惹的。-我觉得是因为你平时也都大吼大叫。说话得温柔点儿。-宝贝,我是不会无缘无故大吼的。
如要要表示某些人或物体“莫名其妙地出现”、“突然冒出来”,我们可以用这个表达:
out of nowhere. 我们来看两个例句: Suddenly, a truck came out of nowhere. 突然,不知从哪儿冒出来一辆卡车。A huge bear appeared out of nowhere and threatened us. 一只大熊不知从哪儿冒了出来,我们都吓坏了。
如果想形容一个人说的话“毫无道理、不着边际”,我们可以用这个表达:make no sense. 来看一个例句: It's hard to argue with him because he makes no sense at all. 和他去争辩是很困难的,因为他根本就不讲道理。
