无限这个说法太笼统, 在不同汉语句子里,应有不同的英语单词与其对应.说某人潜力无限,可以说unlimited,数学上的无限则是infinite,数量无限大说法较多,如countless,numerous.形容地域无限或思想深刻大可以说boundless,unbounded这里给点boundless的用法示例：1. 夕阳无限好，只是近黄昏。The setting sun had boundless beauty, Just because the yellow dusk is so near.2. 掌握无限空间的概念是很难的。It is difficult to grasp the concept of infinite space.3. 无限度的武器竞赛当然会增加战争的危险性。An unlimited arms race may well increase the danger of war.4. 他的无限的慷慨深深地感动了我们。His boundless generosity moved us deeply.5. 无限的耐心使她成为这个医院最好的护士。Her endless patience made her the best nurse in the hospital刚才那些事形容词，这再给出两个名词，其实就是infinite的名词版infinitude[in5finitju:d]n.无限, 无穷数, 无限之物示例：The state or quality of being infinite.无穷：无穷尽的一种状态或品质An immeasurably large quantity, number, or extent:无穷数，无限量：巨大的数量、数字或程度：“[His designs contain] an infinitude of forest shadings for the scenes with animals” (Alan Rich)“他的设计包括 以巨大的树林为背景，并配上动物的画面” (艾伦·里奇)infinity[in5finiti]n.无限, 无穷大【复数】 in.fin.i.ties缩写 inf.示例：The quality or condition of being infinite.无限：无穷无尽的性质或者状况Unbounded space, time, or quantity.无限的空间、时间或者数量An indefinitely large number or amount.无限大的数或量Mathematics The limit that a function ƒ is said to approach at x = a when for x close to a, ƒ(x) is larger than any preassigned number.【数学】 无穷大极限：函数ƒ在接近x = a 处的极限，当 x 接近 a, ƒ(x) 时大于任何预先给定的数A range in relation to an optical system, such as a camera lens, representing distances great enough that light rays reflected from objects within the range may be regarded as parallel.（聚焦区）无限远：与光学系统（如照像镜头）有关的一个范围，表示距离是如此之远，以至于从在这一距离的物体上反射回来的光可以视为平行光线A distance setting, as on a camera, beyond which the entire field is in focus.无限远标志：一个距离的设定，比如在照像机上，表示整个场景都在焦点内
