❹ 初中英语八大时态

初中英语来中的八个基本时自态，即：一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、现在完成时、过去完成时。

时态是一种动词形式，表示经常、反复发生的动作或行为，不同的时态用以表示不同的时间与方式。在语法里，时或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式、将来式，通常也有与表示动作进行或终止的进行式和完成式等体貌一起相连用的情况。

(4)英语八下时态语法扩展阅读

一般过去时与现在完成时的转换：

在现在完成时中，延续性动词能与表示一段时间的状语连用，瞬间动词却不能。但是，可用别的表达方式：①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；②瞬间动词可改成与之相对应的延续性动词及短语，与一段时间连用。

一般现在时与现在进行时的转换
在一般现在时中，at加上名词表示“处于某种状态”，如at work（在工作），at school（上学、上课）等。此短语可与进行时态转换。

现在进行时与一般将来时的转换
在现在进行时态中go，come，leave，start，arrive等动词常与表示将来的时间状语连用表示将要发生的动作。

❻ 八年级英语几个时态的语法要点。

重点语法扫描1. 一般将来时 表示将来某个时间要发生的动作或存在的状态，也表示将来经常或反复发生的动作，常与表示将来的时间状语连用。例如：He will come to see you next month.他下个月将会来看你。Will people use money in five hundred years?500年后人们用钱吗？2. 委婉建议用should should作为情态动词，可用于各种人称，意为“应该”，用于表示劝告、建议等，其否定形式为shouldn’t。例如：You should write a letter to your mother.你应该给你妈妈写封信。He shouldn’t drink and drive.他不应该酒后驾车。3. 过去进行时 表示在过去某个时间正在进行的动作或过去某一阶段一直进行的动作。例如：—What were you doing when your mother came in? 你妈妈进来时你正在干什么？—I was playing computer games. 我正在玩电脑游戏。4. 直接引语与间接引语 直接引语指直接引述别人的原话，而间接引语则指用自己的话转述别人的话。直接引语变间接引语时，要注意在人称和时态上作适当的调整。例如：He said, “I will fly to Paris tomorrow.”→ He said that he would fly to Paris tomorrow / the next day.
