| 背面 |     释义： 1、PIE root dwo-, dwi- "two, double" => two, twice, twain, twin, duo.adv. 两次；两倍 例句： 1. The car passed over the body twice, once backward and then forward.那辆车把那人来回轧了两次，先是倒着轧的，再是往前开着轧的。 twice 两次，两倍twi-,二，-ce,副词后缀。 twicetwice: [12] Twice was formed from Old English twige ‘twice’ (itself based on twi-, the combining form of two) and the genitive ending -s, which was used for creating adverbs, such as always, nowadays, once, thrice, etc.=> twotwice (adv.)late Old English twies, from Old English twiga, twigea "two times," from Proto-Germanic *twiyes (cognates: Old Frisian twia, Old Saxon tuuio), from PIE *dwis-, adverbial form of *dwo- "two" (see two). Spelling with -ce reflects the voiceless pronunciation. Life is as tedious as a twice-told tale Vexing the dull ear of a drowsy man. ["King John," III.iv.] Think twice, then speak was an "old Prouerbe" by 1623. At twice, though less common than at once, means "at two distinct times; by two distinct operations."" |
