Step4 合作交流

Ⅰ现在完成时的用法

1.表示过去发生的或已经完成的某一动作对现在造成的影响或结果。

2.表示过去已经开始，持续到现在动作或状态，可以和表示从过去某一时刻延续

到现在（包括“现在”在内）的一段时间的状语连用。

Ⅱ现在完成时态的结构

have (has)+过去分词

构成:主语 + have/has + 过去分词 + 其他。( 当主语是第三人称单数时用has,其余人称用have。)

否定式:主语 + haven't/hasn't + 过去分词 + 其他。

疑问式: Have /Has + 主语 + 过去分词 + 其他?

肯定答语： Yes, 主语 + have/has. 否定答语：No, 主语 + haven't/hasn't.

过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆.

Ⅲ和现在完成时态连用的时间副词或短语：

1.already,yet,ever,never,just,before

2.once,twice,three times,four times

3.for + 一段时间,since +时间段

4.these days, today,this year,so far ,

Ⅳ现在完成时态使用的注意事项：

1. 表示过去发生的动作或存在状态，一直持续到现在，也许还将继续下去，可以

和for+时间段，since+时间点/从句及how long 连用，谓语动词只可用延续性动词。常见的终止性动词与延续性动词之间的对应关系如下：

come/go/ arrive/reach/get /move to ----be in /at die ----- be dead open ------be open close ---be closed become -----be fall asleep ------be asleep borrow

----keep buy----have begin ,start ----- be on put on -----wear leave -----be away from join the army -----be in the army /be a soldier join the Party ---be in the Party / be in the Party

注意：have/has been与have/has gone区别(见课本)

例：他去过长城。_____________________________________

—他在哪儿？______________________

—他去长城了。___________________________

2. 瞬间动词在完成时态中的否定式可以接一段时间。
