高三原因狀語(yǔ)從句復(fù)習(xí)案例

一、情景導(dǎo)入：

跟同學(xué)們說(shuō)自己喜歡旅游度假，打算乘火車(chē)去北京看香山紅葉，問(wèn)同學(xué)們是否愿意去北京度假。從而引出以下三個(gè)句子：1.MsChensaysthatshewantstogotoBeijingforvacation.2.MsChenaskswherewegoforvacation.3.MsChenwantstoknowifwetakethetraintogoforvacation.讓同學(xué)們自讀觀察這三個(gè)句子的結(jié)構(gòu)特點(diǎn)，找一至兩名同學(xué)分析出賓語(yǔ)從句的特（語(yǔ)序和時(shí)態(tài)）。從而引出本節(jié)課的復(fù)習(xí)目標(biāo)：賓語(yǔ)從句。二、句型展示我把賓語(yǔ)從句分成兩大類(lèi)，五種句式結(jié)構(gòu)：即主句為一般現(xiàn)在時(shí)，從句分別為陳述句、一般疑問(wèn)句、特殊疑問(wèn)句和主句為過(guò)去時(shí)，從句為疑問(wèn)句以及特殊情況。每種類(lèi)型各給出三個(gè)例子，讓同學(xué)們討論句式結(jié)構(gòu)和特點(diǎn)。三、總結(jié)歸納先讓學(xué)生作出初步歸納，老師跟上適當(dāng)點(diǎn)撥和補(bǔ)充，讓同學(xué)們進(jìn)一步明確賓語(yǔ)從句的規(guī)律和特點(diǎn)。四、專(zhuān)項(xiàng)練習(xí)在每一組句型后都跟上專(zhuān)項(xiàng)練習(xí)題，就地記牢。而每一組練習(xí)題都是遵循這樣一種模式：先自主完成，然后老師出示答案，再結(jié)對(duì)或小組內(nèi)相互評(píng)定,最后老師解答個(gè)別難題。第一組：出示例句（主句是一般現(xiàn)在時(shí)，以that做引導(dǎo)詞，討論語(yǔ)序和時(shí)態(tài)）1.MsChenknows(that)weallliketravelling.

2.Ithink(that)IwilltakethetraintoBeijingforvacation.

3.Itseems(that)YuMeihaschangedhermind.先讓同學(xué)們自己讀例句，然后小組內(nèi)討論，再找2個(gè)學(xué)生分析這三個(gè)例句的特點(diǎn)，突破語(yǔ)序和時(shí)態(tài)。預(yù)計(jì)到同學(xué)們會(huì)講解不規(guī)范，所以老師作到心中有數(shù)，時(shí)刻準(zhǔn)備必要的補(bǔ)充。并緊跟上練習(xí)題加以鞏固。練習(xí)題:

合并句子：1.Youarelate.Iamafraid.2.Ithink.He’llbebacknextweek.3.Weallliketravelling.Lilysays.學(xué)生先自己做題，完成后相互交換對(duì)彼此答案的意見(jiàn)，再找2個(gè)學(xué)生出示他們的答案并說(shuō)明原因，就此進(jìn)一步分析賓語(yǔ)從句的時(shí)態(tài)和語(yǔ)序。第二組:（以特殊疑問(wèn)詞做引導(dǎo)詞，重點(diǎn)突破語(yǔ)序）。1.IaskTomwhyhedoesn’tdecidetogowithus.2.LilyasksTomwhenhe’llgotoEngland.3.Weallaskhimwhohecameherewith.學(xué)生自讀句子然后分析歸納，小組內(nèi)交換意見(jiàn)，再找2-3名同學(xué)站起來(lái)為大家分析。老師仍然準(zhǔn)備補(bǔ)充或點(diǎn)撥，強(qiáng)調(diào)陳述語(yǔ)序。練習(xí)題:1.“Wheredoeshelive?”MrHuasks.MrHuasks_________________.2.Doyouremember______youwenttoShanghaiin1980?

A.that

D.where3.Doyouknow________bikethisis?

C.what

D.whose4．---Couldyoutellme_________you’vebeenhere?---Sincelastyear.A.

howfarB.howoftenC.howsoonD.howlong先讓學(xué)生自主完成，之后同組內(nèi)兩人之間相互交換答案，老師出示正確答案，可兩人可小組內(nèi)討論就時(shí)態(tài)和語(yǔ)序問(wèn)題對(duì)答案質(zhì)疑，再找1-2人對(duì)答案進(jìn)行講解。如果仍有問(wèn)題，可給出時(shí)間再做討論或者老師點(diǎn)撥，務(wù)必突破語(yǔ)序問(wèn)題。第三組:（以if和whether做引導(dǎo)詞，重點(diǎn)討論語(yǔ)序）1.Wedon’tknowif/whetherTomwillgotoBeijingforvacation.2.Wedon’tknowwhetherTomwillgotoBeijingornot.

同學(xué)們歸納后，老師要有意識(shí)多重復(fù)幾遍whetherornot,目的讓他們對(duì)“whetherornot”形成定勢(shì)。練習(xí)題：

A.合并句子：

1.Theteacherasks.

DoesTomoftengotoschoolbybike?

Theteacherasks___Tom_____toschoolbybike.

2.DidPetercomehereyesterday?

LiLeiwantstoknow.

LiLeiwantstoknow

__Peter

__hereyesterday.B.完成句子：1.Shehasn’tdecided______shewillgoornot.通過(guò)這幾個(gè)練習(xí)題，我想讓他們學(xué)會(huì)“以一般疑問(wèn)句做從句時(shí)，引導(dǎo)詞用if/whether,并進(jìn)一步掌握主句是一般現(xiàn)在時(shí)態(tài)時(shí)，從句該用什么時(shí)態(tài)就用什么時(shí)態(tài)。第四組:（主句全是一般過(guò)去時(shí)的句型，重點(diǎn)突破時(shí)態(tài)。）LilyknewthatLucyfinishedherhomework.LilywantedtoknowwhenLucydid

herhomework.LucywoneredifLilyhadalreadyfinishedherhomework.著重讓同學(xué)們注意主句時(shí)態(tài)已經(jīng)由原來(lái)的一般現(xiàn)在時(shí)態(tài)變成了一般過(guò)去時(shí)，引導(dǎo)他們發(fā)現(xiàn)從句的時(shí)態(tài)都是過(guò)去的某種時(shí)態(tài)，并就地出示“時(shí)態(tài)一致規(guī)則”讓他們記牢。時(shí)態(tài)一致原則：

當(dāng)主句是一般過(guò)去時(shí)態(tài)時(shí)，從句必須用它相應(yīng)的過(guò)去時(shí)態(tài)；當(dāng)主句是一般現(xiàn)在時(shí)態(tài)時(shí)，從句用它所需要的任何時(shí)態(tài)。練習(xí)題：合并句子1.

Areyouhungry?Mymotheraskedme.

Mymotheraskedme_____________hungry.2.Whyhasn’tshecomeyet?Nobodyknew.

Nobodyknew______________comeyet.重點(diǎn)注意第二題，由現(xiàn)在完成時(shí)變成過(guò)去完成時(shí)難度較大，預(yù)計(jì)一定有不少同學(xué)出錯(cuò)，可以放慢速度多給時(shí)間讓學(xué)生掌握，不留困惑。第五組：（特殊規(guī)定）
