    高中英语时态的知识1
    时态区别
    ①一般过去时与现在完成时:时间上有差异:凡有过去时间的均用过去时态,不能用完成时态,如含有ago、last year、just now、the other day等。
    结果上有差异:现在完成时强调的是对“现在”的影响和结果,动作到现在刚完成或还在继续;一般过去时强调的是动作发生在“过去”,和现在毫无关系。
    ②过去完成时与一般过去时:过去完成时强调的是“过去的过去”;如出现同一主语连续几个动作(“连谓”)形式则只用一般过去时即可。

    现在完成时
    ①现在完成时除可以和for、since引导的状语连用外,还可以和下面的介词短语连用:during / in /over the last(past)few years (months, weeks)、in recent years等。
    ②下列句型中常用现在完成时
    It is (has been) + 一段时间 + since从句
    This(That / It)is the first(second…)time that + 完成时
    This(That / It)is the only … + that + 完成时
    This(that / It)is the best / finest / most interesting … + that 从句 + 完成时
    ③在时间或条件状语从句中,现在完成时可以代替一般将来时。如:

    过去完成时
    ①常用过去完成时的几种情况:
    (A)在by、by the end、by the time、until、before、since后接表示过去某一时间的短语或从句以前发生的动作。如:By the end of last year, we had produced 20,000 cars. The train had left before we reached the station.
    (B)表示曾实现的希望、打算、意图、诺言等。常用had hoped / planned / meant / intended/
    though / wanted / expected等或用上述动词过去式接不定式完成式表示即:hoped / planned … + to have done。
    (C)“时间名词 + before”在句子中作状语,谓语动词用过去完成时;“时间名词 + ago”在句中作状语,谓语动词用一般过去式。如:He said his first teacher had died at least 10 years before. Xiao Hua left school 3 years ago.
    (D)表示“一……就”的几个句型:Hardly / No sooner / Scarcely had + 主语 + 过去分词 + when / than / before + 一般过去时。如:We had no sooner been seated than the bus started. = No sooner had we been seated than the bus started.
