过去将来时过去完成时考点分析考核重点
1）过去完成时考点分析（考核重点）。
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.
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.

2）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。

3）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。

4）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.

5）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。

in / on / to “方位”不同
[ 高手出招 ] 1. Japan is east of Asia .
2 . Tai Wan is the east of Fujian Province .
3 . China faces the Pacific the east .
[ 一语击破 ] 这三个介词都可以表示方位， in 表示“在其中”，即“在境界内”；而 to 表示彼此境界不相接，即“在境界外”； on 则表示“与境界相接”。
