初二英語一般過去時(shí)語法知識(shí)點(diǎn)(2)

 

　　一般過去時(shí)表示的動(dòng)作或狀態(tài)都已成為過去，現(xiàn)已不復(fù)存在。

　　Christine was an invalid all her life.

　　(含義：她已不在人間。)

　　Christine has been an invalid all her life.

　　(含義：她現(xiàn)在還活著)

　　Mrs. Darby lived in Kentucky for seven years.

　　(含義：達(dá)比太太已不再住在肯塔基州。)

　　Mrs. Darby has lived in Kentucky for seven years.

　　( 含義：現(xiàn)在還住在肯塔基州，有可能指剛離去)

　　注意： 用過去時(shí)表示現(xiàn)在，表示委婉語氣。

　　8)動(dòng)詞want, hope, wonder, think, intend 等。

　　Did you want anything else?

　　I wondered if you could help me.

　　2)情態(tài)動(dòng)詞 could, would.

　　Could you lend me your bike?

　　9)used to / be used to

　　used to + do："過去常常"表示過去習(xí)慣性的動(dòng)作或狀態(tài)，但如今已不存在。

　　Mother used not to be so forgetful.

　　Scarf used to take a walk.　 (過去常常散步)

　　be used to + doing： 對(duì)……已感到習(xí)慣，或"習(xí)慣于"，to是介詞，后需加名詞或動(dòng)名詞。

　　He is used to a vegetarian diet.

　　Scarf is used to taking a walk.(現(xiàn)在習(xí)慣于散步)

　　典型例題

　　---- Your phone number again? I ___ quite catch it.

　　---- It's 69568442.

　　A. didn't　　B. couldn't　C. don't　D. can't

　　答案A. 本句雖沒有明確的時(shí)間狀語，但從語意上看 出，在聽的時(shí)候沒有聽懂這個(gè)動(dòng)作發(fā)生在過去，因此應(yīng)用過去時(shí)。

　　10)有些句子，雖然沒有表示過去確定時(shí)間的狀語，但實(shí)際上是指過去發(fā)生的動(dòng)作或存在的狀態(tài)的話，也要用過去時(shí)。

　　I didn't know you were in Paris.

　　我不知道你在巴黎。

　　(因?yàn)樵谡f話時(shí)，我已經(jīng)知道你在巴黎了。這句話指的是說話之前，所以只能用過去時(shí)表示。實(shí)際上，這句話暗指：But now I know you are here.)

　　I thought you were ill.

　　我以為你病了呢。

　　(這句話應(yīng)是在說話之前，我以為你病了。但是現(xiàn)在我知道你沒病)

　　辨別正誤

　　Li Ming studied English this morning.

　　(把此句變?yōu)橐话阋蓡柧?

　　(×)1.Did Li Ming studied English this morning?

　　(動(dòng)詞應(yīng)該用原形)

　　(×) 2. Does Li ming Study English this morning?

　　(時(shí)態(tài)應(yīng)該用原句子的時(shí)態(tài))

　　(×) 3.Was Li Ming studied English this morning?

　　(應(yīng)該用一般動(dòng)詞，而不是be動(dòng)詞)

　　(О) 4.Did Li Ming study Enghish this morning?

　　常見錯(cuò)誤如下:

　　一　把動(dòng)詞變成過去式易出錯(cuò)

　　例: 1 They stoped (stop) talking just now.

　　2 They plaied (play) football yesterday.

　　答案: 1 stopped 2 played

　　解析:我們可以記住下面的口訣:"動(dòng)詞變成過去式,雙寫規(guī)律要牢記;y前若是輔音字,y變i加-ed;y前若是元音字,只須直接加-ed."

　　二忘記把動(dòng)詞變成過去式

　　例: I fly (fly) kites on the afternoon of Sunday.

　　答案: flew

　　解析:我們可以記住下面的口訣:"一般過去時(shí)態(tài)里,過去形式莫忘記".

　　四易與單三人稱作主語的一般現(xiàn)在時(shí)弄混

　　例: He taughts (teach) me English last year.

　　答案: taught

　　解析:行為動(dòng)詞的過去式無人稱和數(shù)的變化.即使主語是單三人稱,也和其它人稱所用動(dòng)詞的形式一樣.

　　五易與現(xiàn)在完成時(shí)弄混

　　例: 我看過這部電影

　　I saw(see) the film.

　　答案: I have seen (see) the film.

　　解析:"我看過這部電影"說明我了解這部電影的內(nèi)容,強(qiáng)調(diào)現(xiàn)在的情況,應(yīng)用現(xiàn)在完成時(shí);

　　一般過去時(shí)態(tài)的句子只是說明我看了這場(chǎng)電影,與現(xiàn)在無關(guān)..
