时态综合复习(2)4月

2 He is going to does (do) his homework after school.
答案：1 be 2 do
解析：第一题有的同学一看he做主语就用了is，忽视了will后应加动词原形。

我们在写句子时，很容易把动词丢掉，“英语句子里，动词不能少”的规律必须要牢记。

第二题中to后加动词原形，而不是用单三人称.
二、be going to +动词原形与will+动词原形用法不清楚
例：我正努力学习，准备参加英语考试。

I am studying hard and I will try for my English exams.
答案：I am studying hard and I am going to try for my English exams.
解析：“be going to” 表示计划、打算要做某事。

E.g. He is going to visit his friends. 还表示某种迹象表明会发生某事.e.g. Look at the clouds. It’s going to rain. 而“Will+动词原形”指对将来事物的预见、表示意愿、决心。

E.g. I will wait for you until you come. 在单纯预测未来时，二者可以互换，但在此题中只能用be going to，而不能用will。

三、There be结构的一般将来时易出错
例：There_________ a basketball match this afternoon. (B)
A is going to be
B is going to have
C are going to be
D are going to have 答案：A
解析：There be结构的一般将来时既要符合There be结构，又要符合一般将来时。

有的同学认为have当“有”讲，所以选了B，但There be结构就不成立了，此句中is是be going to中的，是由后边的单数名词决定的.
四、be going to结构中易丢掉to
例：I’m going _______(go) school by bike tomorrow.(C)
A to will go
B to go to
C go to
D to go
答案：B
解析：由tomorrow可知是一般将来时，be going to +动词原形，所以先确定用to go , 在B、D当中选，而go to school 是固定词组，不能因为前边有一个to而省略，这是一个易错点，需要注意。

另外，在时间状语或条件状语从句中，若主句用了将来时，从句则用一般现在时，前边已经讲过,这里不在重复.

(六)过去将来时
过去将来时表示1) 从过去某时看将来要发生的动作或存在的状态．是在某一过去时之后发生的动作．我们可以理解为它是＂立足于过去，着眼于未来＂的一种时态．
E.g. Li Ming said that you would be happy if you heard from me.
2) 过去将来时还可表示过去习惯性的动作．E.g. Every evening Mr. Wang would go and talk with his students. 过去将来时常用在宾语从句中．主句为过去时，从句表示将要发生的事情．E.g. I didn't know if she would come. 它也常用于间接引语中．E.g. He told me that he would go on a trip to Beijing the next day.
3) 其结构为＂would/should +v". 第一人称用should，其它人称用would．
E.g. I hoped I should be well again very soon. My mother told me she would go shopping.
过去将来时也可以用"was/were going to +v"来表示．E.g. He said that he was going to have a walk with his mother.
注意：go , come, leave, start等表示位置移动的动词，常用过去进行时表示一个当时按计划或安排近期将要发生的事情．
e.g. I have just cleaned the classroom.
2)过去已经开始，一直持续到现在的动作或状态。

注意：此时动作可能还要继续。

（即它的＂未完成用法＂）。

E.g. He has lived in Beijing for ten years.
其结构是“have/has+过去分词”。

过去分词的变化分规则与不规则两种。

规则变化与过去式相同，不规则变化需要另记。

它的否定句是在have/has后边加not，变一般疑问句是把have/has提前。

E.g. I have ridden a horse.
I have not ridden a horse.
Have you ridden a horse?
它的时间状语通常为already, just, yet, ever, never, before等。

另外还可和since+表过去的时间点，for+时间段连用。

做题时常见错误如下：
一、易丢掉have/has
例：He taken (take) the medicine before.
答案：has taken
解析：have/has 为助动词，起构成时态的作用，是不能省略的。

我们可以这样记：“现在完成时态中，have/has 不可缺。

”
二、have与has易用混
例：I has never heard (hear) of that before.
答案：have heard
解析：现在完成时与一般现在时一样也有单三人称的变化，当单三人称作主语时用has, 一般人称作主语时用have．
三、延续性动词与短暂性动词易弄错
例：She has left (离开) for 2 hours.
答案：has been away
解析：在肯定句中，与since或for引出的时间状语连用的是延续性动词，不能是短暂性动词，但在否定句中短暂性动词也是可以的。

E.g. I haven't bought clothes for one year. 在此题中leave是短暂性动词，不能与for+时间段连用，须把它改成相应的延续性动词。

如stop be over等。

此题中leave要改成be away。

这两种词的转换是学习现在完成时需要注意的。

四、have been to与have gone to 易弄混
例：我去过北京。

I have gone to Beijing.
答案：I have been to Beijing.
解析："have been to+地点" 是表示曾去过某地，但此刻不在那儿（即在说话的地方）。

而"have gone to+地点" 是表示去某地了，此刻在路上或已经到了那个地方（即不在说话的地方）。

注意：这两个句式后接副词时，需省to。

E.g. He has gone there.
五、忘记把already变成yet
例：I have already finished my homework.(变一般疑问句)
Have you already finished your homework?
答案：Have you finished your homework yet?
解析：现在完成时态中，肯定句中有already，变否定句或疑问句时通常要改为yet．
六、在条件、时间状语从句中用一般现在时表示将来
例：I'll go with you when I finish(finish) my homework.
答案：have finished
解析：在条件、时间状语从句中表示将来完成的动作，用现在完成时。

但注意，此时表示这动作将在另一动作之前完成，若两动作同时发生，或几乎同时发生，则一般不用现在完成时。

另外，现在完成时易与一般过去时弄混，前边已经讲过,这里不在重复．
