现在进行时过去完成时过去将来时考点分析 1. 现在进行时考点分析。 （1）表示说话时正在发生着的一个动作；表示现阶段但不一定是发生在讲话时；表近期特定的安排或计划；go、come等起止动作可用进行时代替将来时。如： I am meeting Mr. Wang tonight. We are leaving on Friday. At six I am bathing the baby.(I start bathing the bady before six.) The girl is always talking loud in public. (与always、often等频度副词连用，表经常反复的行动或某种感情色彩) （2）下面四类动词不宜用现在进行时。 ①表示心理状态、情感的动作：like, love, hate, care, remember, believe, want, mind, wish, agree, mean, need。 ②表存在的状态的动词：appear, exist, lie, remain, seem belong to, depend on。 ③表示一时性动作的动词：allow, accept, permit, promise, admit, complete。 ④表示感官的动词：see, hear, notice, feel, smell, sound, taste, look。

The train had left before we reached the station. ②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。 ③ “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. ④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. （2）在before或after引导的时间状语从句中用一般过去时态代替过去完成时。 After he (had)left the room, the boss came in. We arrived home before it snowed. 3. 过去将来时考点分析。 参照一般将来时对比：用would do、was / were going to do sth.表过去将来；come、go、leave等过去进行时表过去将来时；was / were to do sth.和was / were about to do sth.表过去将来。 4. 过去进行时考点分析。 （1）过去某一时刻正在进行的动作或某一阶段内发生或频繁发生。 （2）某一动作发生时另一动作正在发生，其中一个在由when或while引导的时间状语从句中。 5. 现在完成时考点分析。 （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： I shall post the letter as soon as I have written it. If you have done the experiment, you will realize the theory better. Don’t get off the bus until it has stopped. 6. 注意几组时态的区别： （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。
