常见考法

1. 基本概念的考查;

2. 和被动语态一起考查以增加难度;

3. 将空设在从句中。

误区提醒

1.对“过去的过去”认识不清;

2. 受被动语态等因素的影响;

3.有从句时主从时间的先后辨别不清。

【典型例题】

1.The students ___ busily when Miss Brown went to get a book she ___ in the office.

A. had written, left

B. were writing, has left

C. had written, had left

D. were writing, had left

解析:"把书忘在办公室"发生在"去取书"这一过去的动作之前,因此用过去完成时。句中when表示的是时间的一点,表示这时"同学们正忙于……",因此前一句应用过去进行时,正确答案D。

2. The policeman’s attention was suddenly caught by a small box which ____ placed under the Minister’s car.

A. has been

B. was

C. had been

D. would be

解析:错选B。本题中的“过去”是“was suddenly caught”; “放小盒子”是在“过去”的前面,因此要用过去完成并且是被动语态,因此空是在定语从句中,有一定难度。正确答案C。

四级英语知识点总结

四级英语知识点总结 四级英语知识点总结 英语不像汉语可以有固定的形容过去与现在的词语,要想表达不同时间的内容就必须懂得时态的转换。英语中事情发生的时间可分为现在、过去、将来和过去将来四种形式,发生的方式可分为一般、过去、进行和完成进行四种形式。 将时间形式和动作方式结合起来,就构成了以下:一般、完成、进行、完成进行几种时态。下面我们为大家仔细总结了英语中常用的几种时态,希望对大家的考试有所帮助。 现在:现在一般时do、现在完成时have done、现在进行时is doing、现在完成进行时have been doing 过去:过去一般时did、过去完成时had done、过去进行时was doing、过去完成进行时had been doing 将来:将来一般时will do、将来完成时will have done、将来进行时will be doing、将来完成进行时will have been doing、过去将来:过去将来一般时would do、过去将来完成时would have done、过去将来进行时would be doing、过去将来完成进行时would have been doing 英语的时态是靠动词的变化和时间状语来表达的。英语中的时态共有十六种,但是常考的或较常用的只有9种。 要掌握英语的时态和语态,必须掌握好英语中的助动词:第三人称单数:does。

主语+be+v.ing〔现在分词〕形式 They have lived in Beijing for five years. 他们在北京已经住了5年了。 4、一般过去时 表在过去某个特定时间发生且完成的动作,或过去习惯性动作,不强调对现在的影响,只说明过去。常跟明确的过去时间连用,如:yesterday; last week; in 1945, at that time; once; during the war; before; a few days ago be动词+行为动词的过去式,否定句式:在行为动词前加didnt,同时还原行为动词,或waswere+doing+其它 Beijing was hosting the 29th Olympic Games in August 2008. 在20xx年8月,北京正在举行29届奥运会。 6、过去完成时 表示过去某个时间之前已经完成的动作,即过去完成时的动作发生在“过去的过去”,句中有明显的参照动作或时间状语,这种时态从来不孤立使用。 7、一般将来时 表在将来某个时间会发生的动作或情况。常和tomorrow, next year等表示将来的时间状语连用。 am/are/is+going to+do 或will/shall+am/is/are/about to + do 、am/is/are to + do;

初中英语知识点总结:现在完成时

初中英语知识点总结:现在完成时 现在完成时指的是过去发生并且已经完成的动作对现 在造成影响或后果,过去某一时间开始并一直持续到现在并 且有可能还会持续的动作或状态。 1 、现在完成时用来表示过去发生或已经完成的动作对 现在造成影响或后果。也就是说,动作或状态发生在过去但它 的影响现在还存在,强调的是现在。 例如:I have already posted the photo.我已经把照片寄走了。强调post对现在的影响“照片不在这里”。 2、现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作或状态,常与for,since连用.谓语动词必须是延续性动词。例如:He has lived here since 1978.自从1978年以来,他一直住在这儿。(动作起始于1978年,一直住到现在,可能还要继续住下去。) 注意:for和since的用法。 ①for+时段为…时间 ②since+过去一个时间点 ③since+时段+ago ④since+从句 ⑤It is+时段+since+从句 注:瞬间动词不能直接与for 或since 引导的时间段连

用。要改变成延续性动词。变化如下:come/arrive/reach/get to-----be in go out----be out finish----be over open----be open die----be dead Buy---have Fall ill---be ill Come back---be back Put on ---be on/wear Worry---be worried Catch a cold---have a cold 三、现在完成时往往同表示不确定的过去时间状语连 用,如already, yet, just, before, recently,still, lately,never等. 例如:He has already finished the work.. 对于现在完成时的考查,多以单选、句型转换或词语运 用的形式考查学生在具体语境中灵活运用时态的能力。在考 试中,会让大家判断是否该用现在完成时,或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。 典型例题1:His father_____the party since 1978 joined in been in 解析:本题考查学生对现在完成时的熟练掌握。since 1978表达“自从1978年一直到现在”,表示这件事情从过去 一直持续到现在,应该用现在完成时,而且动词必须是延续 性动词,AB均为瞬间动词,不能与时间段连用,故排除;C 为一般过去时,也不行。 答案;D. 一般过去时和现在完成时的用法区别是我们要注意的

英语过去完成时的用法总结
