      復數(shù):?blasts;第三人稱單數(shù):?blasts;過去式:?blasted;過去分詞:?blasted;現(xiàn)在分詞:?blasting;

      助記提示


      1. 不能夠持續(xù)就爆炸, 爆炸就是那種瞬間炸開的東西,而不是那種持續(xù)性的、慢慢的發(fā)生的那種情形。
      2. 不持續(xù)就爆炸. 無法持續(xù)只能爆炸.
      3. blast => clast: c‐開,炸開了巖石成碎屑.
      4. 由b到c, 這是字母順序關聯(lián)性,因此clast可以看成是blast爆炸后的結果.

      英文詞源


      blast (n.)
      Old English bl?st "blowing, breeze, puff of wind," from Proto-Germanic *bles- (cognates: Old Norse blastr, Old High German blast "a blowing, blast," German blasen, Gothic blesan "to blow"), from PIE *bhle- "to blow," probably a variant of root *bhel- (2) "to blow, inflate, swell" (see bole).

      Meaning "explosion" is from 1630s; that of "noisy party, good time" is from 1953, American English slang. Sense of "strong current of air for iron-smelting" (1690s) led to blast furnace and transferred sense in full blast "the extreme" (1839). Blast was the usual word for "a smoke of tobacco" c. 1600.
      blast (v.)
      Old English bl?stan "to blow, belch forth," from the root of blast (n.). Since 16c., often "to breathe on balefully." Meaning "to blow up by explosion" is from 1758. Related: Blasted; blasting. Blast off (n.) is attested from 1950.
