现在完成时现在完成时（present perfect tense）通常表示过去发生的动作一直延续到现在，而且还可能继续下去，或者表示过去的行为对现在造成一定的影响，可能还会产生结果等。

1.现在完成时结构1.1.助动词have/has+动词过去分词。

其中，助动词要随着主语的变化而变化，当主语是第三人称单数时，助动词要用“has”。

例：Have you finished your work?He says that he has seen UFOs many times.1.2.现在完成时的缩写形式：I have=I ’ve have not= haven’thas not= hasn’t例：I’ve finished my work./He hasn’t finished his work.1.3.现在完成时的一般疑问句：Have/Has+主语+动词的过去分词+其他？肯定回答：Yes,主语+have/has.否定回答：No,主语+haven’t/hasn’t.例：----Have you finished your work?----Yes,I have./No,l haven’t.----Have they arrived?----Yes,they have./No,they haven’t. 1.4.1.通过加-ed的形式来构成规则动词的过去分词，就像我们构成这些动词的过去式方法一样。

大多数动词后+ed.如finish---finished.以字母e为结尾的动词后+d,如change---changed.以辅音字母加y结尾的动词，去掉y,再加ied.如carry---carried.以一个元音再加一个辅音结尾的短动词，双写辅音辅音字母再加ed.如stop---stopped1.4.2.构成不规则动词的过去分词的方法有所不同，需要特别记忆。

如：come---come; hurt---hurt. lend---lent; build---builtcatch---caught; keep---kept forget---forgotten tell---toldbe---been; have---had fall---fallen; fly---flowndraw---drawn; see---seen；think---thought.2.现在完成时的用法2.1.表示过去发生或已经完成的动作，对现在造成的影响或结果。
