accelerate 加速

前綴ac-同ad-.詞根celer,加速，見celerity,迅速。

accelerate: accelerate: [16] Accelerate comes from Latin accelerāre, a compound verb formed from the intensive prefix ad- (ac- before /k/ sounds) and celerāre ‘hurry’. Celerāre, in turn, derived from the adjective celer ‘fast’ (which gave English celerity [15] and is ultimately related to hold).
accelerate (v.): 1520s, from Latin acceleratus, past participle of accelerare "to hasten, quicken," from ad- "to" (see ad-) + celerare "hasten," from celer "swift" (see celerity). Related: Accelerated; accelerating.

1. We need to accelerate the pace of change in our backward country.: 我們應當為落后的祖國加快變革的腳步。

2. Perhaps the fact that the car was tailgating him made him accelerate.: 或許是因為那輛汽車跟得太緊，他才加速的。
