总结：现在完成时
• 含义 1 :__________________ • 结构：肯 __________________
否___________________ 一般疑问 ___________________ 特殊疑问____________________ • 标志词|:____________________
Tips:buy 这个动作 从“开始发生”到 “结束/终止”, 几
乎同时或在极短的时间里（如‘几秒钟/几分钟内’）就完 成了“开始—结束”的过程，这样的动词我们叫做短暂性 动词。 所以， “我买了这块手表5年了”，在汉语中说的 通，但英语中就必须用相应的延续性动词来替换。
19
现在完成时中常见的非延续性动词
16
• 2 标准词：so far/up to now (到目前为止） ;lately/recently(最近）
• Up to now/So far ,I haven’t been successful. • Lately/Recently,I haven’t seen my teacher.

I bought the book five days ago. I have bought the book. I have bought the book for five days. I have had the book for five days. I have had the book since five days ago.
非延续性动词： buy borrow die leave begin/start come / go
finish 这些动词时，要把它们变成相应的延续性动词
