scan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),后接名詞或代詞作賓語。
scan的過去式和過去分詞均為scanned。
scan本身就有“細(xì)看,審視”的意思,所以一般不與careful連用。例如: 那男人審視著醫(yī)生的臉。誤:The man scanned the doctor's face carefully.正:The man scanned the doctor's face.
scan還可用作名詞,作“掃描”解。例如:The first scan was bad, so I had to do it again .第一次掃描不好,所以我得重做。
