知识点归纳

现在完成时/ 现在完成进

1.知识点

概述

现在完成时（Present perfect）过去发生并且已经完成的动作对现在造成影响或后果，过去某一时间开始并一直持续到现在的动作或状态。简而言之即过去发生并且已经完成且持续了一段时间的。

接触一：肯定句式现在完成时的肯定句式是“have（has）＋过去分词”。如：

①We have just finished our homework．

②She has gone home．

注意：

1）该句式中的have或has是助动词，has用于第三人称单数，其它人称一律用have。

2）该句式中have（has）和过去分词之间可用just插入。

3）把该句式译成汉语时，往往用“已经”、“刚刚”、“过”或“了”等。

接触二：否定句式：现在完成时的否定句式是“haven't（hasn't）＋过去分词”。如：

⑥We haven‘t studied Unit 2 yet．

⑦The train hasn't stopped yet．

接触三：疑问句式现在完成时的一般疑问句式是把助动词have或has提到主语之前。

③Have you read this story book yet？

特殊疑问句及反意疑问句结构如下：

④What have you done with my bike?

⑤You have read this story book, haven't you?

注意：1）现在完成时的一般疑问句往往在句末加yet。

2）把现在完成时的一般疑问句译成汉语时，

往往译成“……过吗？”、“已经……了吗？”等。

3）其肯定回答用“Yes，．．．have（has）．”，

否定回答用“No，．haven't（hasn't）．”，有时用“No，not yet．”或“No，never．”。

already, yet, ever, never, just的用法

①、Already 肯定句，强调已经的意,放句中或句末.

4.知识点

for, since及how long

For + 时间段：表示某个动作持续了多长时间

Joey has been in New York for 10 years.

Since + 时间点（具体时间/ … ago/ 某个动作发生的时间）：

表示某个动作是从什么时候开始的，间接地表示这个动作持续的时间

两者都可以回答由How long引导的问题。
