九年級(jí)英語(yǔ)期末賓語(yǔ)從句復(fù)習(xí)資料

字號(hào):

這篇九年級(jí)英語(yǔ)期末賓語(yǔ)從句復(fù)習(xí)資料的文章,是特地為大家整理的,希望對(duì)大家有所幫助!
    復(fù)習(xí)目標(biāo):
    1、掌握引導(dǎo)賓語(yǔ)從句的各種連詞
    2、掌握賓語(yǔ)從句的語(yǔ)序--主句+連接詞+主語(yǔ)+謂語(yǔ)
    3、掌握賓語(yǔ)從句,主句與從句在時(shí)態(tài)上的呼應(yīng)。
    重點(diǎn):語(yǔ)序和時(shí)態(tài)呼應(yīng)
    難點(diǎn):語(yǔ)序和時(shí)態(tài)呼應(yīng);與疑問(wèn)詞+不定式的轉(zhuǎn)化;與狀語(yǔ)從句的辨析
    考點(diǎn)梳理:
    一、賓語(yǔ)從句的連接詞:
    1、連詞that,只起連接作用,在從句中不作句子成分,也無(wú)詞匯意義,在口語(yǔ)中常被省略。
    eg. He knew (that) he should work hard.
    2、連詞if 、whether,它們起連接作用,在從句中不作句子成分,作“是否”解,在口語(yǔ)中多用if。
    eg. Tom don’t know if/whether his grandpa liked the present.
    He asked me whether or not I was coming.
    一般情況下,if 和whether可以互換,但以下3種情況只能用whether:
    ①在不定式前:Whether to go there or not hasn’t been decided.
    ②在介詞前:It depends on(依靠) whether it is going to rain.
    ③與or not連用:They are talking about whether to go there or not.
    3、連接代詞who, whom, whose, what, which,連接副詞when, where, why, how, 它們起連接作用,作句子成分,各有自己的意義。
    eg. The teacher asked the new students which class he was in.
    I wonder where he got so much money.
    【注意】1、由連接代、副詞引導(dǎo)的賓語(yǔ)從句可以和“疑問(wèn)詞+不定式”結(jié)構(gòu)轉(zhuǎn)化。
    eg. I don’t know how I should do with the presents. è I don’t know how to do with the presents.
    2、要注意區(qū)分判斷由if、when引導(dǎo)的從句類(lèi)型.
    二、賓語(yǔ)從句的語(yǔ)序:
    賓語(yǔ)從句的語(yǔ)序是陳述語(yǔ)序,即“連接詞+主語(yǔ)+謂語(yǔ)+其它成分”。特別強(qiáng)調(diào):它的主語(yǔ)和謂語(yǔ)的語(yǔ)序是陳述語(yǔ)序,而不是疑問(wèn)句的倒裝結(jié)
    構(gòu)。
    Can you tell me who(m) do we have to see?(╳)
    Can you tell me who(m) we have to see?( √)
    The teacher asked the students what they were doing.(思考: what在從句中的成分)
    陳述句變?yōu)橘e語(yǔ)從句時(shí),要注意人稱和時(shí)態(tài)的變化,語(yǔ)序不變。 eg. She said, “I will leave a message on the desk.” à She said
    she would leave a message on the desk.
    一般疑問(wèn)句和特殊疑問(wèn)句變?yōu)橘e語(yǔ)從句時(shí),也要注意人稱和時(shí)態(tài)的變化,后面接陳述語(yǔ)序。Eg. “Where are the tickets?” I asked him.
    à I asked him where the tickets are.
    三、賓語(yǔ)從句的時(shí)態(tài)呼應(yīng):
    賓語(yǔ)從句中謂語(yǔ)動(dòng)詞的時(shí)態(tài),常常受到主句謂語(yǔ)時(shí)態(tài)的制約,此為時(shí)態(tài)呼應(yīng)。如果主句謂語(yǔ)是一般現(xiàn)在時(shí)或?qū)?lái)時(shí),從句謂語(yǔ)的時(shí)態(tài)不受
    限制;如果主句謂語(yǔ)的時(shí)態(tài)是一般過(guò)去時(shí),從句一般要隨著改為相應(yīng)的過(guò)去時(shí)態(tài)(一般過(guò)去時(shí)、過(guò)去進(jìn)行時(shí)、過(guò)去將來(lái)時(shí)、過(guò)去完成時(shí))。
    eg. I thought (that) you are free today. (╳)
    I thought (that) you would be free today. ( √)
    【注意】當(dāng)賓語(yǔ)從句敘述的是客觀真理時(shí),不管主句謂語(yǔ)的時(shí)態(tài)如何,從句都用一般現(xiàn)在時(shí)。
    eg. The teacher told us (that) the earth moves around the sun.
    四、其他需要說(shuō)明的問(wèn)題:
    1、標(biāo)點(diǎn)由主句決定,如主句是陳述句、祈使句,則用句號(hào);是疑問(wèn)句則用問(wèn)號(hào)。
    eg. I heard she had been to the Great Wall. Can you tell me which bus I should take?
    2、要注意個(gè)別句子中主從句人稱的一致。
    ▲五、賓語(yǔ)從句和狀語(yǔ)從句的區(qū)分:
    eg. 1) I will go out tomorrow if it is fine tomorrow.
    2) I don’t know if the train has arrived.
    句1中if引導(dǎo)的是狀語(yǔ)從句。這個(gè)從句表示“條件”,修飾主句。整個(gè)句子的意思是如果明天天氣好,我就出去。句2中if引導(dǎo)的是賓語(yǔ)從
    句,充當(dāng)謂語(yǔ)動(dòng)詞don’t know的賓語(yǔ)。整個(gè)句子的意思是我不知道火車(chē)是否已到達(dá)。
    判斷方法:
    1、可以從整個(gè)句式看。狀語(yǔ)從句一般可以放在主句的前面或后面(個(gè)別除外),賓語(yǔ)從句只能放在主句謂語(yǔ)動(dòng)詞之后。
    2、從引導(dǎo)詞看。if充當(dāng)賓語(yǔ)從句的連接詞時(shí),相當(dāng)于whether, 詞義為“是否”,充當(dāng)狀語(yǔ)從句的連接詞時(shí),詞義為“如果”。when充當(dāng)
    賓語(yǔ)從句的連接詞時(shí),意為“什么時(shí)候”, 充當(dāng)狀語(yǔ)從句的連接詞時(shí),意為“當(dāng)……的時(shí)候”
    3.從時(shí)態(tài)看。if和when作連接詞時(shí),引導(dǎo)賓語(yǔ)從句要注意:從句的謂語(yǔ)動(dòng)詞的時(shí)態(tài)應(yīng)根據(jù)主句的時(shí)態(tài)作相應(yīng)的變化。if和when充當(dāng)從屬連
    詞時(shí),引導(dǎo)條件和時(shí)間狀語(yǔ)從句,若主句的謂語(yǔ)動(dòng)詞用一般將來(lái)時(shí),則從句的時(shí)態(tài)應(yīng)用一般現(xiàn)在時(shí)表示將來(lái)。
    e.g. I think (that) differences are not important in a friendship.
    An old lady said (that) she found a job as a foreign language teacher.
    They don’t know if (是否)we are going hiking next weekend
    Could you tell me when (什么時(shí)候)the train arrives ?
    We’ll go to the Great Wall if (如果) it doesn’t rain tomorrow.
    =If doesn’t rain tomorrow, we’ll go to the Great Wall.
    They knew each other when(當(dāng)……時(shí)候)they were children.
    =When they were children
