终止性动词也称非延续性动词,它所表示的动作一经发生立即完结,不再延续。常见的这类动词有:come, go, leave, open, begin, start, finish, stop等。 在使用终止性动词时,应注意以下四点: 一、终止性动词不用于进行时态,若是进行时态形式应译成将来时态的意思。如: The spacecraft is returning to the earth. 宇宙飞船就要返回地面了。 I'm leaving for Lanzhou.我要出发去兰州。 二、 终止性动词不能与how long引导的疑问句连用。如: 不能说:How long have you left school? 应该说:How long is it since you left school? 或者说:How long ago did you leave school? 三、终止性动词不能与for引导的表示一段的时间状语连用。如: 不能说:He has bought the computer for two months. 应当说:He has had the computer for two months. 或者说:He bought the computer two months ago. 也可说:It is two months since he bought the computer. 还可说:Two months have passed since he bought the computer. 但有些终止性动词的否定形式可与表时间段的状语连用。如: I haven't heard from him for six months. He hasn't come here for a week. 四、 终止性动词与until引导的时间状语(或从句)连用时,只能用否定形式,不能用肯定形式。如: I didn't know until yesterday.直到昨天我才知道这件事。 He didn't return until midnight.他直到午夜才回来。 Don't get off the bus until it has stopped.等到汽车停妥后再下车。 |
