| 释义 | current (once / 52 pages) 1adj 2n If it's in the past, it's not current. If it's out of date, out of style, or out of time, it's not current. If it's up-to-the-minute, right now, and in the present, it is current. Origins of the word current all point to the meaning "present." Things that are current are happening now; they are part of the present time. News reporting looks at "current affairs" because past affairs are no longer news; they are history.
