现在完成时中短暂性动词与延续性动词的转换(共18张PPT)

现在完成时中 (点动词)短暂性动词与延续性动词的转化 短暂性动词 也称做点动词、非延续性动词或瞬间动词。 表示动作不能延续，只是一瞬间就结束的动作。 常见的短暂性动词 come, go, arrive, reach, see, hear, close, open, leave, begin, start, lose, buy, fall, join, die, become, borrow, get up 等． １.它们可以用于完成时态，说明某个动作的结 果还存在 e.g. He has come back. The film has begun. 2.在否定句中，非延续性动词也可以用表示一段时间的状语来修饰 e.g. I haven’t heard from Uncle Wang for a long time. We haven’t seen him since 1992. She hasn’t left home all her life. 在以下句型中，短暂性动词要转换成延续性动词： 现在完成时态的肯定句中，有for或since引导的，或其他种类的表示一段时间的时间状语 例如：He has died for 20 years. 这句话就是错误的。 die是一个瞬间动词，需要转化为延续性动词。 句子改为 He has been dead for 20 years. 非延续性动词要转换成延续性动词，方法主要有以下三种： 1. 实义动词转化成实义动词 1. borrow keep 2. buy have 3. put on wear 2. 转化成be+形容词或介词 1. go there be there 2. come here be here 3. come back be back 4. die be dead 5. leave be away (from) 6. open be open 7. close be closed 8. go/get out be out 9. finish/end be over 10. become be 11. get up be up 12. begin/start(上演) b
