4）动词过去式变化规则。 a)一般情况下的词加-ed. work---worked call----called b)以不发音的字母e结尾的单词直接加-d . live----lived change----changed smoke----smoked die----died graduate----graduated drive----drove
8.过去完成时表示动作发生在过去某一时间之前已经完成的动作或状态，强调“过去的过去”，常与 by the time, by the end of…,before , by 等引导时间的状语连用。
基本结构主语+ had + 动词过去分词 + 其他成分 When I got to the cinema yesterday the film had begun already. He had learned English before he came here.
现在完成时与一般过去时的区别： 1)现在完成时侧重于对现在的影响；而一般过去时侧重于某一动作发生在过去某个时间或某段时间。即现在完成时侧重于现在的结果，而一般过去时侧重于动作发生的时间。例如：
I have seen the film. 我看过这部电影。(现在我仍记得电影的内容) I saw the film three days ago. 三天前我看了这部电影。(强调是三天前,而不是别的什么时候看的电影)
be going to含有“打算，准备”的意思，而will则没有这个意思， She is going to lend us her book. He will be here in half an hour.
be about to＋V.原形（意为马上做某事，在时间上指最近的将来） I am about to leave school. 不能与表示时间的副词连用。 They are about to set out.(√) They are about to set，变y为i加-ed. study----studied carry----carried cry----cried try----tried d)以元音字母＋y结尾的单词直接加-ed. play----played stay----stayed

做题时常见错误四、对do的理解易出错
❖ 例：根据动词完形填空 We _______ (not do) our homework in the afternoon. 我们不在下午做家庭作业。
❖ 答案：1 don't do
❖ 解析：do是一个比较难理解的词，它有三个含义: a)是所有行为动词的总称； b)是助动词，无实义； c)是一个具体的行为动词“做，干”。
❖ 时间状语：
often（经常）、 usually（通常）、 always （总是）、 sometimes（有时）等频率副词， on Saturdays（在星期六）、 in the morning(afternoon evening)（在早上（下午晚上））、every day（每天）等。
一般现在时的句子结构
动词原形变第三人称单数形式的一般规则： 1、一般情况加s 2、以ch、sh、s、x、o、结尾加es 3、以辅音字母加y结尾变y为i加es
一般现在时的句子结构
2、含有实义动词的句子，变否定句或者一般疑问句就要借用助动词来帮忙。
助动词有两个do，does，只有当主语是第三人称单数时要借助助动词does，其余人称都用do。变疑问Do/Does放主语前；变否定主语之后don't/dosen't添，借助助动词谓语动词需还原。
1、含有be动词的句子，一般现在时be（am，is， are)要变否定句和一般疑问句就根据be动词用法口诀走：
be动词有3个am/is/are,具体用哪一个根据主语的变化而变化，我是am，I am，你是are， You are, 还有We are 和They are, is 连着他她它，he is; she is; it is, 单数名词用is ，复数名词全用are，变疑问（be）往前提，句末问号莫忘记，变否定更容易be后not莫忘记，疑问否定任你变句首大写莫迟疑。

目录
PART 01
be动词基本概念与分类
REPORTING
在倒装句中，如果谓语部分含有 be动词，通常将be动词提到主语前面，例如：Here is the book you want. （你要的书在这儿。）这句话的正常语序是“The book you want is here.”，倒装后将be动词is提到了主语the book前面。
另外，在一些特殊句型中，be动词的位置也会有所调整，需要根据具体句型来判断。例如：Not only was he late， but he also forgot his books. （他不仅迟到了，还忘了带书。）这句话中使用了not only…but also…结构，并且not only位于句首，因此主句采用了部分倒装的形式，将 was提到了主语he前面。
be动词的过去完成时为had been，表示过去某个时间之前已经存在的状态或进行的动作。
使用场景：描述过去某个时间之前已经完成的动作或存在的状态，强调动作的先后顺序。
