3. 师生共同学习现在完成时的概念、构成及用法。
(一) 观察下面两个句子的斜体部分，注意它们的用法，并归纳出现在完成时的含义、构成
形式及基本用法。
(1)He has just bought a bicycle. (= He has a bicycle now.)
(2)They have stayed in Shanghai since 1998. (=They began to live in Shanghaimany years
ago, and now they still live in Shanghai.)
(二) 从上面例句可以归纳出：
(1)现在完成时的两种意义：
①表示过去发生的动作对现在产生的结果或造成的影响。（如：例1）
②表示过去发生的动作或开始的状态一直延续到现在,并且可能持续下去。（如：例2）
(2)现在完成时的构成形式： have (has) + 过去分词(past participle)
(3)现在完成时的具体用法（一）：
e.g. They have finished the work already.
表示过去的动作finish对现在产生的结果是：已经完成了工作，无需再做工作了。e.g. She has just lost her English book.
表示过去发生的lose这个动作，对现在造成的影响是：她没有英语书了。
注意：①这两个动词都是瞬间动词（非延续性动词），表示动作在过去发生的，瞬间就结束了，动作不存在延续的情况。
②这两个动作是过去发生的，正因为它们对现在产生了影响，与现在的情况有一种
必然联系，它强调了过去与现在的联系。这也是现在完成时与一般过去时的区别
所在，因为一般过去时只说明过去，与现在无关。
试练[填空]：我以前从未见过他。I ______ never _______ him before.
她的姑妈已经去世了。Her aunt _______ already _______ .
(4)现在完成时的具体用法（二）：
e.g. I have lived here for almost ten years.
表示过去的动作live一直延续到现在，差不多有10年的时间了。live 是延续性动词。
e.g. She has been in Japan since 2001.
表示过去开始的状态一直延续到现在，从2001年直到现在。be in是可以延续的状态。注意：①在这种情况下，要用延续性动词或一种可以延续的状态，后面可以接for + 一段时间；或者可以接since + 过去某一个时间点或过去某个动作。
②它强调过去和现在的一种关系，即过去的动作或状态一直延续到现在。后面有一
段时间。
