　　時(shí)態(tài)是一門重要的語(yǔ)法知識(shí)，是我們學(xué)習(xí)句型的基礎(chǔ)。以下是小編為大家整理的關(guān)于時(shí)態(tài)的語(yǔ)法知識(shí)，希望能幫到你。

　　一、不用進(jìn)行時(shí)的動(dòng)詞

　　4) 系動(dòng)詞

　　二、用一般過(guò)去時(shí)代替完成時(shí)

　　1) 構(gòu)成will / be going to do sth.

　　2) 概念

　　a. 狀態(tài)完成：表示某事繼續(xù)到將來(lái)某一時(shí)為止一直有的狀態(tài)。

　　b. 動(dòng)作完成：表示將來(lái)某一時(shí)或另一個(gè)將來(lái)的動(dòng)作之前，已經(jīng)完成的動(dòng)作或一獲得的經(jīng)驗(yàn)。

　　They will have been married for 20 years by then.

　　You will have reached Shanghai by this time tomorrow.

　　三、過(guò)去完成時(shí)

　　1) 概念：表示過(guò)去的過(guò)去

　　----|-------|-----|---->其構(gòu)成是had +過(guò)去分詞構(gòu)成。

　　那時(shí)以前　 那時(shí)　現(xiàn)在

　　2) 用法

　　a.　在told, said, knew, heard, thought等動(dòng)詞后的賓語(yǔ)從句。

　　She said (that) she had never been to Paris.

　　b. 狀語(yǔ)從句

　　在過(guò)去不同時(shí)間發(fā)生的兩個(gè)動(dòng)作中，發(fā)生在先，用過(guò)去完成時(shí);發(fā)生在后，用一般過(guò)去時(shí)。

　　When the police arrived, the thieves had run away.

　　c. 表示意向的動(dòng)詞，如hope, wish, expect, think, intend, mean, suppose等，用過(guò)去完成時(shí)表示"原本…，未能…"

　　3)　過(guò)去完成時(shí)的時(shí)間狀語(yǔ)before, by, until , when, after, once, as soon as。

　　He said that he had learned some English before.

　　By the time he was twelve, Edison had began to make a living by himself.

　　典型例題

　　The students ___ busily when Miss Brown went to get a book she ___ in the office.

　　A. had written, left　B，were writing, has left　 C. had written, had left　D. were writing, had left

　　答案D. "把書忘在辦公室"發(fā)生在"去取書"這一過(guò)去的動(dòng)作之前，因此"忘了書"這一動(dòng)作發(fā)生在過(guò)去的過(guò)去，用過(guò)去完成時(shí)。句中when表示的是時(shí)間的一點(diǎn)，表示在"同學(xué)們正忙于……"這一背景下，when所引導(dǎo)的動(dòng)作發(fā)生。因此

　　前一句應(yīng)用過(guò)去進(jìn)行時(shí)。

　　注意：　had no … when　　　還沒等…… 就……

　　had no sooner… than　　剛…… 就……

　　He had no sooner bought the car than he sold it.
