用法辨析
- speed作名詞的基本意思是“速度,速率”,指運(yùn)動(dòng)事物在單位時(shí)間內(nèi)所通過的距離。作此解時(shí), speed本身無所謂快慢,若表示“快”或“慢”,須加形容詞修飾。可用作可數(shù)名詞,也可用作不可數(shù)名詞,用作可數(shù)名詞時(shí),其前常加不定冠詞a。
- speed也可作“快,快速”解,指運(yùn)動(dòng)本身的速度、頻率快,是不可數(shù)名詞。
- speed后常接of短語作定語,有時(shí)speed可用在名詞前作定語。
- speed用作動(dòng)詞是“提速”“加速”的意思,含有“有成效”而不帶有興奮與慌亂的意味,也可指駕車者以違法的速度行駛。
- speed可用作及物動(dòng)詞,也可用作不及物動(dòng)詞。用作及物動(dòng)詞時(shí),接名詞或代詞作賓語。
n. (名詞)
v. (動(dòng)詞)
