很多人在备考四级的时候都忽略了语法的备考，这就导致备考的过程中困难重重，今天我们为大家整理了英语四级语法基础知识大全，一起来看一下吧。

I' 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

3)将来完成进行时∶将来某个时刻以前一直在进行的动作.

4)将来完成时(由shall/will have + 过去分词构成)∶ 将来某时已发生的事，

语态

可以有两种被动结构的类型，例如∶

It 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 sunk.

The ship is supposed to have been sunk.

双宾语及宾补结构的被动语态

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—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.
