| 释义 | trigger The transitive verb trigger is a relatively new word. We first encountered it in 1916: • ... blows the ionized gas through the hole in the disk to the other terminal, thus triggering off the spark — Scientific American, 29 Aug. 1916 Its widespread use dates only from the 1940s, when it began to appear in a variety of publications: • Libido ... is not triggered by the glands, but by the brain —Time, 28 Apr. 1941 • ... that the alpha particle serves only to trigger off the nuclear disintegration —J. D. Stranathan, The Particles of Modern Physics, 1942 • Then Pearl Harbor triggered the mass migration to the west coast shipyards —N. Y. Herald Tribune, 21 Nov. 1943 Its use became even more common in the 1950s, and it has continued to be extremely popular in the decades since: • ... it triggered a complex and very public chain of events —Tom Wolfe, in The Contemporary Essay, ed. Donald Hall, 1984 • ... could have triggered a potentially disastrous run on deposits —Julie Salamon, Wall Street Jour., 18 Dec. 1981 • ... appears that such movements have indeed triggered large earthquakes —W. Thatcher, Nature, 8 Sept. 1982 • The split with the Johnsons was triggered by Mr. Johnson's belief —Garrison Keillor, Lake Wobegon Days, 1985 Usage commentators agree that trigger is a reputable verb, but several of them consider it overused, and they recommend giving preference to such alternatives as start, cause, initiate, produce, and begin (to name a few). Trigger does, however, have distinct connotations that make it an especially appropriate choice in many cases: it typically implies an immediate effect or reaction, usually an unintended or undesirable one. These useful connotations will doubtless assure its continuing popularity. We see no need to make a special point of avoiding its use. |
