| 释义 | 〔till〕Till and until are generally interchangeable in both writing and speech, though as the first word in a sentenceuntil is usually preferred: Till 和 until 普遍认为在口语和书面语中都可通用， 而作为句子的第一个词时，until 更为常用： 〔act〕The wordsact and action both mean "a deed" and "the process of doing.” However, other senses ofact, such as "a decision made by a legislative body" and of action, such as "habitual or vigorous activity" show that act tends to refer to a deed while action tends to refer to the process of doing. The demands of meaning or idiom will often require one word or the other:class act and class action, for example, are not interchangeable. In cases where either can be used, either is acceptable: myact (or action ) was premature. act 及 action 两者都表示“行为”和“行动的过程”。 然而，act 的其他释义，如“立法机关所做的决定”及 action 的其他释义， 如“惯常的或充满活力的活动”表明act 偏重于指行动而 action 偏重于指行动的过程。 由于意义和习语的需求，通常只能用其中的一个单词，如：class act（出类拔萃的人） 和 class action（共同起诉） 不能互换。 在二者皆可的情况下，二者可通用：我的行为 （或 行动 ）太草率 |
