一、现在完成时的构成 （以下所有例句翻译成汉语）

（一）肯定式 主语＋助动词have ／has ＋过去分词＋其它

说明：这里的have ／has是助动词，没有什么具体意义。当主语是第三人称单数时助动

南中学案 英语 （必修二） A 词用has，其余人称一律用have。 has，have的缩略式分别为's或've。实例： 1）I've just copied all the new words ． (表示不要再抄了) 2）She has lost her books ． （表示到目前为止还没有找到） (如果用过去时She lost her books.则强调书是过去丢的这一动作，而不知现在有没有找到) 3）We've just cleaned the classroom ． （表明现在教室是干净的） （二）否定式 主语＋助动词have ／has＋not＋过去分词＋其它

说明：现在完成时构成否定句时，只需在助动词have ／has后面加not就行。have not，has not的缩略式分别为haven't ，hasn't。另外，肯定句中有some，already时，改为否定时要分别改成any，yet。

实例： 1）I haven't finished my homework yet． 2）She hasn't travelled on a train ． 3）We have never spoken to a oreigner． 注：有时not可以用never代替，表示“从来没有”的意思。又如：

4）I have never seen him before． （三）一般疑问式 助动词Have ／Has ＋主语＋过去分词＋其它 ？

说明：把陈述句中的have或has放到句首，句末打问号，同时把句中的some ，already改为any ，ye t就构成了一般疑问句。肯定回答用“Yes ，主语＋have／has．否定回答用“No，主语＋haven't／hasn't．”有时也可以用“No，not yet．／No ，never．／No，not even

once．”等。实例： 1）—Have you ever made dumplings ？ —Yes ，I have ．是的，我做过。 2）—Has she ever been abroad ？ —No，never．不，从来没有。 3）—Have they found the lost books yet ？ —Yes ，they have．是的，他们找到了。 注意：当句中有否定词not ，hardly（几乎不），never的时候，在改为反意疑问句时，附加部分用肯定形式。例如：You have never come to our school ，have you ？

（四）现在完成时地被动语态：主动语态即主语为动作的执行者；被动语态即主语为动作的承受者。现在完成时的被动语态同它的主动语态一样，强调过去的动作对现在造成的影响或结果，但主语为动作的承受者，表示“……已经被……”。如：

The new school has been set up. 2) 现在完成时被动语态的肯定式为：have / has + been + done。如：

The experiment has been done successfully. 现在完成时被动语态的否定式为：have / has + not + been + done。如：

Tom’s novel has not been published. 现在完成时被动语态的一般疑问句需将have / has提到主语的前面。如：

Has his bike been repaired? 现在完成时被动语态的特殊疑问句为：疑问词 + have / has + been + done。如：

Who has been invited? （五）现在完成时被动语态的主要用法1．表示被动的动作发生在说话之前（即现在的过
