英语语法动词总结:
1.时态
1)现在完成进行时态 (have/has been + -ing 分词构成): 动作或状态从过去某时开始,继续到现在,可能继续下去,也可能刚刚结束.I’ve been writing letters for an ’ve been sitting in the garden.
2)过去完成进行时(由had been + ing分词构成): 过去某个时刻以前一直在进行的动作I’d been working for some time when he had been waiting for her for two hours by the time she came.

4)将来完成时(由shall/will have + 过去分词构成): 将来某时会业已发生的事.I shall have finished this one before ’ll have hit the year’s target by the end of October.
2.语态
1)可以有两种被动结构的类型,例如:He was said to be jealous of her was said that he was jealous of her success.
能同时适用于上述两个句型的主动词通常都是表示“估计”,“相信”等意义的动词,常见的有assume,believe,expect,fear,feel,know,presume,report,say,suppose,understand等.It is supposed that the ship has been ship is supposed to have been sunk.
担当be supposed to 与不定式的一般形式搭配时往往表示不同的意义.例如:Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你应该晓得速度限制)
2)双宾语及宾补结构的被动语态a)双宾语结构的被动语态: 双宾语结构变为被动语态时,可以把主动结构中的一个宾语变为主语,另一个宾语仍然保留在谓语后面,但多数是把间接宾语变为主语.He was asked a number of questions at the press days were allowed them for making the necessary preparations.

初一英语助动词的用法:
只有实意动词作谓语时才涉及使用助动词。以like为例:
1)当句子为肯定句时不涉及使用助动词,只涉及"主谓一致"原则。
eg : I like English a lot.
Michael likes Chinese food very much.
2)当句子为否定句时,要根据主语的人称来决定使用相应的助动词:当主语为"三单"时,要使用does;当主语为"非三单"时,用助动词原形do。例如把下列句子变否定句:
Kangkang likes math.----Kangkang doesn't like math.
They like sports.------They don't like sports.
3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句:
Michael likes Chinese Food.----Does Michael like Chinese food? Yes, he does./ No, he doesn't.
Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.
初中英语动词不定式用法:
一、用作主语
直接把动词不定式置于句首的情况不多,多数情况用it作形式主语,把真正的主语——动词不定式置于句末,特别是不定式短语较长时。动词不定式作主语,谓语动词用第三人称单数形式。带疑问词的不定式短语作主语常置于句首,复合不定式结构作主语常置于句末。如:
无论是形式主语,还是形式宾语,都要用it,不能用其他词。切记!
young adults, it is our duty to try our best to deal with each challenge... ()
it是形式主语,真正的主语是文中的划线部分。
head teacher said it was necessary to talk with his mother.()
to make requests politely is important.()
划线部分看成三单形式。
二、用作表语
动词不定式作表语,常说明主语的内容、性质、特征。如:
为什么大家写不出长句子?没有大量的积累。多背诵,多思考。
best way to improve your English is to join an English club.()
first thing is to greet the teacher. ()
