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”。
(Keys : 1. in 2. to 3. on )
