视频来源:Youtube 看出来了吗?题目和大家玩儿了个双关哦~^O^ Inertia 的本义 [ɪˈnəːʃə] n. 懒惰,惰性 It is difficult for us to overcome inertia. 我们很难克服懒惰。 图片来源:123rf If you want to be an excellent [ˈeksələnt] person, you have to defeat inertia. 如果你想成为一个优秀的人,你就必须战胜懒惰。 Government inertia is a serious problem. 政府懒惰是个严重问题。
Inertia的引申义 Inertia的引申义 n. 惯性 在物理学中,inertia指惯性,即当一个物体不受任何外力时,它将保持静止或匀速直线运动。 Inertia is the tendency [ˈtendənsi] of a physical object to remain still or to continue moving uniformly ['ju:nɪfɔ:mlɪ] forward in a straight line, unless a force is applied to it. 惯性是指物体保持静止或匀速直线运动,除非受到外力的作用。 图片来源:giphy The little car has less inertia than a big truck. 小汽车比大卡车的惯性小。 图片来源:anjungsainssmkss
词汇拓展 Inertia从何而来? Inertia源于拉丁文inert,而inert源于拉丁文in+ert,其中in-表示否定,-ert同“ars”,表示技能。
Inert [ɪˈnɜ:t] adj. 一动不动的 He opened the back door of the van [væn] and motioned [ˈməʊʃnd] Betsy inside as Molly lay inert on the ground. 他打开货车的后门,示意贝特西进去,而茉莉正躺在地上一动不动。
adj. 呆滞的,迟缓的 The government was perceived [pəˈsi:vd] to be inert and inefficient. 政府通常被认为是迟缓、低效的。
在化学中,inert意为惰性的,不活泼的。 Nitrogen [ˈnaɪtrədʒən] is a very inert gas: it will neither burn nor support the combustion [kəmˈbʌstʃən] of ordinary combustibles [kəmbʌs'təblz]. 氮气是一种惰性气体:既不会燃烧,也不会支持普通可燃物的燃烧。
回顾吧 开篇视频的核心内容,一起回顾吧~ When traveling in a train or any other vehicle [ˈvi:əkl], have you noticed how you continue to move forward when it stops? 当乘坐火车或其他交通工具时,你注意到当车停驶时,你是否继续向前? You just experienced inertia! 你刚刚就是经历了惯性! Inertia is the tendency of a body to resist a change in motion or rest. 惯性是身体阻抗其运动或静止状态的一种趋势。 When a vehicle stops, you tend to jerk [dʒɜ:k] forward before coming to a complete stop. 当车辆停止时,在完全停止前,你倾向于往前冲。 In the same way, you will jerk backwards when the vehicle begins to move. 同样的,当车辆启动时,你会向后倾。 This phenomenon [fəˈnɒmɪnən] occurs because of Newton’s First Law of Motion: an object at rest (or motion) will continue to be in the same state unless acted upon by an external [ɪkˈstɜ:nl] force, which means objects tend to keep on doing what they are doing unless disturbed [dɪˈstɜ:bd]. 这种现象的发生源于牛顿第一定律:静止(或移动)的物体将继续保持原状,除非受到外力的作用,这就意味着物体将继续保持原来的形态,除非受到干扰。 编辑:兔子 |
