❹ 初中英語八大時態
初中英語來中的八個基本時自態,即:一般現在時、一般過去時、一般將來時、過去將來時、現在進行時、過去進行時、現在完成時、過去完成時。
時態是一種動詞形式,表示經常、反復發生的動作或行為,不同的時態用以表示不同的時間與方式。在語法里,時或時態表示行為發生的時間和說話時的關系。一般分為過去式、現在式、將來式,通常也有與表示動作進行或終止的進行式和完成式等體貌一起相連用的情況。
一般過去時與現在完成時的轉換:
在現在完成時中,延續性動詞能與表示一段時間的狀語連用,瞬間動詞卻不能。但是,可用別的表達方式:①瞬間動詞用於「一段時間 + ago」的一般過去時的句型中;②瞬間動詞可改成與之相對應的延續性動詞及短語,與一段時間連用。
一般現在時與現在進行時的轉換
在一般現在時中,at加上名詞表示「處於某種狀態」,如at work(在工作),at school(上學、上課)等。此短語可與進行時態轉換。
現在進行時與一般將來時的轉換
在現在進行時態中go,come,leave,start,arrive等動詞常與表示將來的時間狀語連用表示將要發生的動作。

❻ 八年級英語幾個時態的語法要點。
重點語法掃描1. 一般將來時 表示將來某個時間要發生的動作或存在的狀態,也表示將來經常或反復發生的動作,常與表示將來的時間狀語連用。例如:He will come to see you next month.他下個月將會來看你。Will people use money in five hundred years?500年後人們用錢嗎?2. 委婉建議用should should作為情態動詞,可用於各種人稱,意為「應該」,用於表示勸告、建議等,其否定形式為shouldn』t。例如:You should write a letter to your mother.你應該給你媽媽寫封信。He shouldn』t drink and drive.他不應該酒後駕車。3. 過去進行時 表示在過去某個時間正在進行的動作或過去某一階段一直進行的動作。例如:—What were you doing when your mother came in? 你媽媽進來時你正在干什麼?—I was playing computer games. 我正在玩電腦游戲。4. 直接引語與間接引語 直接引語指直接引述別人的原話,而間接引語則指用自己的話轉述別人的話。直接引語變間接引語時,要注意在人稱和時態上作適當的調整。例如:He said, 「I will fly to Paris tomorrow.」→ He said that he would fly to Paris tomorrow / the next day.
❼ 英語中怎麼辨別語法中的八大時態
它們有自己的時態
比如is
are
am
是現在時態
was
were
是過去時態
這些都可以看出來
還有一些要根版據語句的語境自權己推導
比如
有時候出題人會把幾個時態混合起來
讓你填時態
還有的有些固定短語或者單詞要用固定的時態
