初二上冊英語語法總結(jié)

初二上冊英語語法總結(jié)

動詞不定式一.定義：

動詞不定式是非謂語動詞的一種，它沒有人稱和數(shù)的變化，在句子中不能獨立作謂語，但它仍保持動詞的特點，既可以有自己的賓語和狀語。同時動詞不定式又具有名詞、形容詞、副詞的特征，在句中可以作主語、表語、賓語、賓語補足語、定語和狀語。

二.動詞不定式的構(gòu)成：to+動詞原形

三.動詞不定式作賓語

后面能接不定式作賓語的動詞有：agree,ask,choose,decide,forget,hope,learn,want,wish,wouldlike等。

Wehopetogettherebeforedark.我們希望天黑以前到那兒。Thegirldecidedtodoitherself.那個姑娘決定自己做那件事。動詞不定式作賓語的注意事項（2點）

1.有些動詞既可跟不定式作賓語，也可跟動名詞作賓語，但含義不同：remembertodo記住要做某事

rememberdoing記得曾經(jīng)做過某事forgettodo忘記要做某事forgetdoing忘記曾經(jīng)做過某事stoptodo停下來去做某事stopdoing停止做某事

goontodo繼續(xù)做另一件事goondoing繼續(xù)做原來在做的事

Irememberseeingyousomewherebefore.我記得以前在哪兒見過你。

Pleaseremembertoturnoffthelightwhenyouleave.

離開時請記得關(guān)好燈。

2.不定式作賓語時，如帶有賓語補足語，則要把不定式放到后面，用it作形式賓語，構(gòu)成“主語+動詞+it+賓補（形容詞、名詞）+不定式”結(jié)構(gòu)。如：Hefounditverydifficulttogettosleep.他發(fā)現(xiàn)很難入睡。

四.動詞不定式作賓語補足語1.后面能接to不定式作賓語補足語的動詞有：ask,order,teach,tell,want,wish,help等。

TheteachertoldustodoExercise1.老師要我們做練習(xí)一。Iwantbothofyoutogo.我要你們倆去。

Wehelpedher(to)repairherbike.我們幫助她修理自行車。

2.使役動詞let,have,make及感官動詞see,watch,notice,hear,feel等要以不帶to的不定式作賓補。

Let’shavearest.我們休息一會吧。Isawhimcomein.我看見他進來了。

感官動詞后既可跟不帶to的不定式作賓補，也可跟v-ing作賓補，前者表示動作的全部過程已結(jié)束；后者表示動作正在進行。

Isawhimcomedownstairs.我看見他下了樓。（說明他下樓了這件事）Isawhimcomingdownstairs.我看見他在下樓。（說明他下樓時的情景）

五.動詞不定式作狀語

Laterhelefthometoworkindifferentcities.不久他離開家到不同的城市工作。Hewenttoseeafootballmatch.他去看足球比賽了。Inordertocatchtheotherstudents,Imustworkhard.為了趕上其他同學(xué)，我必須努力學(xué)習(xí)。

六.動詞不定式作定語

不定式作定語一般放在所修飾的詞的后面。Ineedsomethingtoeat.

Doyouhavesomethingtoread?

Tomwassoexcitedthathehadnowordtosay.Heisreallyafoolonlytoeat.

ThemantostandherejustnowisourEnglishteacher.Thedoctorhadnowaytosavethepatient.注意：

（1）作定語的不定式是由及物動詞組成，被修飾的名詞或代詞與不定式之間存在方位或方式關(guān)系需要有介詞。

Iamlookingforaroomtolivein.我正在找一間住房。（方位關(guān)系）Wehavemanythingstodoexperimentswith.我們有許多做實驗的東西（方式關(guān)系）

（2）作定語的不定式是由“be+adj+prep”構(gòu)成的動詞短語。Herethereisn’tanybookformetobeinterestedin.

Wehavedonemanythingstoproudof.我們做了許多引以自豪的事。

七.動詞不定式作主語Togiveisbetterthantoreceive.

Toreachthereonfootisimpossible.

動詞不定式作主語時，可以用it代替，把實際主語不定式放在后面。It’sbettertogivethantoreceive.It’simpossibletoreachthereonfoot.It’s+adj+forsb.todosth.

It’snotdifficultformetostudyEnglishwell.

It’seasyforhimtoworkoutthismathproblem.

在這個句型中，如果形容詞與不定式的邏輯主語關(guān)系密切，并且形容詞用來說明邏輯主語的性質(zhì)、品質(zhì)、特點等，由of引出邏輯主語。這類形容詞主要有nice,kind,good,wrong,right等。

八.動詞不定式和疑問詞連用

動詞不定式可以和疑問詞what,which,how,where,when連用，構(gòu)成不定式短語，可以作主語、賓語、表語、賓語補足語等。

Howtodoisstillaquestion.

Haveyoudecidedwhentoleave?

九.動詞不定式的否定形式

動詞不定式的否定式是在to前加not；不帶to的不定式則在動詞前加not.如：ZhangMingaskedmenottostayathomeallday.張明要我不要整天呆在家里。

Mymotherletmenotdoitbymyself.媽媽讓我不要獨自做這件事。

被動語態(tài)

英語有兩種語態(tài)：主動語態(tài)和被動語態(tài)

主動語態(tài)（TheActiveVoice）表示主語是動作的執(zhí)行者。被動語態(tài)（ThePassiveVoice）表示主語是動作的承受者。構(gòu)成：承受者+助動詞be+及物動詞的過去分詞+by+執(zhí)行者

一般現(xiàn)在時：承受者+助動詞am/is/are+及物動詞的過去分詞+by+執(zhí)行者一般過去時：承受者+助動詞was/were+及物動詞的過去分詞+by+執(zhí)行者承受者+助動詞shall/willbe+及物動詞的過去分詞+by+執(zhí)行者承受者+助動詞have/hasbeen+及物動詞的過去分詞+by+執(zhí)行者承受者+can/may/must/should+be+及物動詞的過去分詞+by+執(zhí)行者被動語態(tài)用法：

1）當(dāng)我們不知道動作的執(zhí)行者是誰，或者沒有必要指出動作的執(zhí)行者時，需用被動語態(tài)。

2）當(dāng)我們需要強調(diào)動作的承受者時,常用被動語態(tài)。

3）如果需要說出動作的執(zhí)行者,用by引導(dǎo)出動作的執(zhí)行者。主動語態(tài)變?yōu)楸粍诱Z態(tài)時，其謂語動詞的時態(tài)要與原句時態(tài)保持一致，其謂語動詞的數(shù)要與新主語保持一致。

主動語態(tài)變?yōu)楸粍诱Z態(tài)時有以下幾種情況：1）主語＋謂語動詞＋賓語

將主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語。（主動）Weboughtabookyesterday.（被動）Thebookwasboughtyesterday.

2）主語＋謂語動詞＋間接賓語＋直接賓語

將主動語態(tài)中一個賓語變?yōu)楸粍诱Z態(tài)的主語。多數(shù)情況下將間接賓語變?yōu)橹髡Z。如果直接賓語變?yōu)橹髡Z時，間接賓語前要加介詞to/for。（主動）Heshowedmeabookyesterday.（被動）Iwasshowedabookyesterday.（被動）Thebookwasshowedtomeyesterday.3）主語＋謂語動詞＋復(fù)合賓語

含有一個由賓語加賓語補足語構(gòu)成的復(fù)合賓語，變?yōu)楸粍诱Z態(tài)時，將主動語態(tài)的賓語變?yōu)楸粍诱Z態(tài)的主語，賓語補足語保留不變，成為主語補足語。（主動）Ifoundhimagoodpupil.（賓語補足語）（被動）Hewasfoundagoodpupil.（主語補足語）4）短語動詞變?yōu)楸粍诱Z態(tài)

有些短語動詞相當(dāng)于一個及物動詞，其后可以接賓語，因此它們也有被動語態(tài)，但短語動詞是不可分割的整體，變?yōu)楸粍诱Z態(tài)時不可去掉其后面的介詞或副詞。（主動）Weshouldlookafterthepatientsverywell.

（被動）Thepatientsshouldbelookedafterverywellbyus.5）賓語從句變?yōu)楸粍诱Z態(tài)

若主動語態(tài)中是賓語從句，變?yōu)楸粍诱Z態(tài)時常用it作形式主語，而把真正的主語放在后面。

It’ssaidthathepassedtheexam.被動語態(tài)應(yīng)注意的幾個特殊問題：

（1）不及物動詞帶介詞和介詞賓語，在變?yōu)楸粍诱Z態(tài)時，仍然要帶上介詞。（主動）Thestudentsinclasslistentotheteachercarefully.（被動）Theteacherislistenedtocarefullybythestudentsinclass.

（2）當(dāng)動詞帶有復(fù)合賓語時，并且賓補是省去“to”的動詞不定式時，在被動語態(tài)中應(yīng)加上“to”。

（主動）Theymakedoallthework.

（被動）Weweremadetodoallthework.

（主動）WeoftenhearhersingEnglishsongs.（被動）SheisoftenheardtosingEnglishsongs.（主動）Iseehimwalktoschool.（被動）Heisseentowalktoschool.
