1、初中语法时态之 （六）现在完成时【概念】现在完成时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,也可表示过去已经开始,一直延续到现在的动作或状态。【结构】主语 + have/has + 过去分词(当主语是第三人称单数时用has,其余人称用have。)（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。)【现在完成时态句式】否定式:主语 + havent/hasnt + 过去分词 + 其他。（has not=hasnt; have not=havent）一般疑问式: Have /Has + 主语 + 过去分词 + 其他?简略答语: Yes, 主语 + have/ha
2、s. (肯定回答) No, 主语 + havent/hasnt.(否定回答)【现在完成时的标志】以下四大标志词可以表达这种含义: 1）* 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 2）* 以ever和never为标志ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 3）* 以动作发生的次数为标志若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 4）* 以so far为标志so far往往表示到目前为止动作或状态已经发生。【针对性练习题】初二现在完成时专项练习一、 单项选择。1、
