【導(dǎo)讀】時(shí)態(tài)其實(shí)是指的兩個(gè)概念:其一是指時(shí)間,其二是指:在不同的時(shí)間條件下動(dòng)詞的形式。時(shí)間上英語主要分為三段:過去時(shí)間,現(xiàn)在時(shí)間和將來時(shí)間。動(dòng)詞的形式有五種,情態(tài)動(dòng)詞。同學(xué)們一定要掌握各個(gè)動(dòng)詞的五種變化形式,這是學(xué)好時(shí)態(tài),做好時(shí)態(tài)題的基礎(chǔ)。重要,其實(shí)他們大錯(cuò)特錯(cuò)了。時(shí)態(tài)的定義是判斷該不該用這種時(shí)態(tài)最重要的依據(jù),同學(xué)們。除了要記住而且要去理解各種時(shí)態(tài)定義的真正含義)。掌握了后再進(jìn)行全面的、深入的學(xué)習(xí)。另外動(dòng)詞原形變動(dòng)詞的三單,一定要詢問老師學(xué)會(huì)哦!一段時(shí)間+ago、,threedaysago,anhourago,twoweeksago,tenyearsago…Now=atpresent;atthemoment現(xiàn)在、目前、此刻atthismoment/time. 請(qǐng)記住下面的例句:

  

【正文】 in New York City for ten years. ( 4) It is the first / second time.... that… 結(jié)構(gòu)中的從句部分用現(xiàn)在完成時(shí)。例如: It is the first time that I have visited the city. 這是我第一次訪問這城市。 This is the first time ( that) I39。ve heard him sing. 這是我第一次聽他唱歌。 但是注意: It was the third time that the boy had been late. ( 5) This is +the 形容詞最高級(jí) +that… 結(jié)構(gòu), that 從句要用現(xiàn)在完成時(shí)。 例如: This is the best film that I39。ve ( ever) seen. 這是我看過的最好的電影。 (6) It’s / It has been + 一段時(shí)間 + since + 一般過去 態(tài)的 時(shí)間狀語從句 ” “自從 … 以來 , 已經(jīng) …( 時(shí)間 )了 ”。如 It’s / has been three months since he moved to this city.(注意 從句 的 謂語動(dòng)詞 須是終止性動(dòng)詞。 ) 4 時(shí)間標(biāo)志詞: ( 過去完成時(shí)的重點(diǎn)在于表達(dá) “過去的過去 ”,是一種相對(duì)的時(shí)態(tài),是以某個(gè)過去的事為參照對(duì)象,強(qiáng)調(diào)的是比它還要早發(fā)生。理解了這一點(diǎn),就比較容易很好地掌握和運(yùn)用這個(gè)時(shí)態(tài)。 ) By the time+一般過去時(shí)態(tài)的從句。在 …… .之前,到 … ..為止。 例句: By the time I got outside , the bus had already left . By the time he was twelve, Edison had began to make a living by himself. by the end of +過去時(shí)間。 在 …… .之前,到 … ..為止。 by the end of last year(term, month…) before+過去時(shí)間或一般過去時(shí)態(tài)的從句。在 ……… 以前。 I had never e here before yesterday .
