九年級英語語法知識點整理歸納一
一、過去完成時與現(xiàn)在完成時的區(qū)別
現(xiàn)在完成時表示的動作發(fā)生在過去，以現(xiàn)在的時間為基點，但側(cè)重對現(xiàn)在產(chǎn)生的結(jié)果或造成的影響，與現(xiàn)在有關(guān)，其結(jié)構(gòu)為“助動詞 have (has) + 過去分詞”;過去完成時則是一個相對的時態(tài)，已過去時間為基點，它所表示的動作不僅發(fā)生在過去，更強調(diào)“過去的過去”，只有和過去某時或某動作相比較時，才用到它。
比較：I have learned 1000 English words so far.到目前為止我已經(jīng)學(xué)會了 1000 個英語單詞。
I had learned 1000 English words till then.到那時為止我已經(jīng)學(xué)會了 1000 個英語單詞。
— I'm sorry to keep you waiting. 對不起，讓你久等了。
— Oh, not at all. I have been here only a few minutes.沒什么，我只等了幾分鐘。(“等”的動作從過去某一時間點持續(xù)到現(xiàn)在)
二、過去完成時與一般過去時的區(qū)別
雖然這兩種時態(tài)都表示過去發(fā)生的動作或存在的狀態(tài)，但在使用時應(yīng)注意以下幾點：
1. 時間狀語不同：過去完成時在時間上強調(diào)“過去的過去”;而一般過去時只強調(diào)過去某一特定的時間。
比較：They had arrived at the station by ten yesterday.
They arrived at the station at ten yesterday.
2. 在沒有明確的過去時間狀語作標志時，謂語動詞動作發(fā)生的時間先后須依據(jù)上下文來判斷：先發(fā)生的用過去完成時，后發(fā)生的則用一般過去時。
She was very happy. Her whole family were pleased with her, too.She had just won the first in the composition competition.
3. 當(dāng)兩個或兩個以上接連發(fā)生的動作用 and 或 but 連接時，按時間順序，只需用一般過去時來代替過去完成時;另外，在 before ， after ， as soon as 引導(dǎo)的從句中，由于這些連詞本身已經(jīng)表示出時間的先后，因此也可以用過去時來代替過去完成時。
He entered the room, turned on the light and read an eveningpaper.

九年級英語語法知識點整理歸納二
語法：直接引語變間接引語。
直接引用別人的話叫直接引語，用來轉(zhuǎn)述別人的話叫間接引語。例：
Hesaid,"HewillgotoBeijingtomorrow."(直接引語)
HesaidthathewouldgotoBeijingthenextday.
直接引語變間接引語時時態(tài)、人稱及一些時間或個別詞都要做相應(yīng)的改變。
①時態(tài)：
一般現(xiàn)在時→一般過去時一般將來時→過去將來時
現(xiàn)在進行時→過去進行時一般過去時→過去完成時
現(xiàn)在完成時→過去完成時
_真理性的句子時態(tài)不變。例：
Hesaid:"Thesunrisesintheeast."
Hesaidthatthesunrisesintheeast.
他說太陽從東方升起。
?、跁r間：
now→then,lastmonth→themonthbefore.
today→thatday,threedaysago→threedaysbefore.
tonight→thatnight,tomorrow→thenextday.
yesterday→thedaybefore,thedayaftertomorrow→intwodays.
?、燮渌兓?/p>
this→thatthese→thosehere→there
come→go
句式的改變：
?、僦苯右Z是陳述句加"that"可以省去。例：
Hesaid,"Mysisterwasherethreedaysago."→
Hesaidthathissisterhadbeentherethreedaysbefore.
?、谥苯右Z是一般疑問句，變成用if/whether引導(dǎo)的賓語從句，人稱時態(tài)等作相應(yīng)改變。
Motheraskedme,"Didyoubuyanymeatforlunch?"→
Motheraskedmeif/whetherIhadboughtsomemeatforlunch.
?、壑苯右Z是特殊問句，變成由原來疑問詞一樣的連接詞引導(dǎo)的賓語從句，時態(tài)人稱等作相應(yīng)改變。例：
"Whatdoyoudo?"heaskedme.
HeaskedmewhatIdid.
?、苤苯右Z是選擇問句變成由whether或if引導(dǎo)的賓語從句。
"DoyoulikeEnglishorChinese?"Heaskedme.
HeaskedmewhetherIlikedEnglishorChinese.
語法：被動語態(tài)
1.英語中動詞有兩種語態(tài)：主動語態(tài)和被動語態(tài)
主動語態(tài)表示主語是謂語動詞動作的執(zhí)行者，被動語態(tài)表示主語是謂語動詞動作的承受者。
當(dāng)我們強調(diào)誰是某個動作的執(zhí)行者，即"誰做了某種事情"時，用主動語態(tài)。
eg:Danielboughtanewcomputer丹尼爾買了一臺新電腦。(不是別人)
如果主語不是動作的執(zhí)行者，而是動作的承受者時，就是被動語態(tài)。
eg:AnewcomputerwasboughtbyDaniel一臺新電腦被丹尼爾買了。
被動語態(tài)的謂語由be+動詞的過去分詞構(gòu)成，其中be是助動詞，隨時態(tài)改變。
一般現(xiàn)在時的被動語態(tài)由"am/is/are+動詞的過去分詞"構(gòu)成。
一般過去時的被動語態(tài)由"was/were+動詞的過去分詞"構(gòu)成。
2.被動語態(tài)的用法：
當(dāng)不知道或沒必要說明動作的執(zhí)行者時，用被動語態(tài)。
eg:RiceisgrowninSouthChina.華南種植水稻。(沒必要說明是誰種)
Thisbridgewasbuilt100yearsago.這座橋是100年前建的。(不知道誰建的)
Passivevoicewith'by'
在被動語態(tài)中，如果我們也要把動作的執(zhí)行者表達出來的話，我們就在被動句子的后面，用"by+動作的執(zhí)行者(賓格)"來表示。
e.g.Jackbrokethewindow.(主動語態(tài))
ThewindowwasbrokenbyJack.(被動語態(tài))窗戶是被杰克打碎的。
Mealsarecookedbyhermotherathome.在家飯是她母親燒的。
Thebookwaswrittenbyhimseveralyearsago.這本書是他幾年前寫的。
3.難點：
1).當(dāng)一個含有復(fù)合賓語(賓語+賓補)的句子變?yōu)楸粍诱Z態(tài)時，只能把賓語變?yōu)楸粍诱Z態(tài)的主語，賓補還放在原來的位置。
e.g.WecallhimXiaoWang.---HeiscalledXiaoWang.
Hecuthishairshort.---Hishairwascutshort.
2).帶雙賓語的動詞變?yōu)楸粍诱Z態(tài)時，常常把間接賓語變?yōu)楸粍诱Z態(tài)的主語;如果直接賓語變?yōu)楸粍诱Z態(tài)的主語時，間接賓語前要加介詞to或for.
e.g.Someonegavetheboyanapple.--Theboywasgivenanapple.
Anapplewasgiventotheboy.
Hismotherboughtapresentforhim.---Hewasboughtapresent.
Apresentwasboughtforhim.
3).在let,hear,watch,see,help,have等詞的句子中，主動語態(tài)不加to,被動語態(tài)要加to.
e.g.Thebossmakesuswork12hoursaday.---Wearemadetowork12hoursaday.
Theyheardthechildrensingthatmorning.---Thechildrenwereheardtosingthatmorning.
⑤直接引語是祈使句，根據(jù)說話語氣變成ask/tell/orderwarnsb.todosth.的結(jié)構(gòu)。例：
Shesaidtome,"Standup."→
Sheaskedmetostandup.
Fathersaidtohisson,"Don'tplayfootballinthestreet."→
Fathertoldhissonnottoplayfootballinthestreet.
語法：祈使句
表示命令、叮囑等的句子叫祈使句。祈使句省略主語，以動詞原形開頭，常加please表示客氣。常有以下三種結(jié)構(gòu)：
(1)行為動詞開頭。例：
Sitdown,please.(Pleasesitdown.)
Comehere.
Gothere.
(2)系詞be開頭。
Becareful!
Besilent.
(3)Let開頭。例：
Let'sdoitatonce.
Lethimdoit.
注：(1)祈使句的否定式在句首加don't。例：
Don'tspeakinChinese.別用漢語說。
Don'tbeheresoearly.別來這太早。
(2)在祈使句前可以加never或always。
Neverclimbuptoohigh.It'sdangerous.
Alwayscomeontime.總是準時。
Alwaysbepolitetoothers.總是對人禮貌。
語法：并列句
由并列連詞but，and，or，so，while等構(gòu)成的并列句，例：
HehelpsmeandIhelphim。
Hewasill，buthestillworkedon。
Helikescookingwhilehiswifelikestravelling。
語法：條件狀語從句，以if引導(dǎo)。
if在英語中可以構(gòu)成條件狀語從句，意為“如果”，也可以構(gòu)成賓語從句，意為“是否”。例：
Idon‘tknowifhewillcometomorrow。(賓從)
我不知道他明天是否來。
Ifhecomes，I’llletyouknow。(條從)
如果他來，我讓你知道。
_1)在if構(gòu)成的條件狀語從句中，如果主句是將來時，或祈使句或有情態(tài)動詞，從句通常用一般現(xiàn)在時。如上面的例句，再如：
Hecanpasstheexamifhestudieshard。
如果他努力學(xué)習(xí)會通過考試的。
(2)if構(gòu)成的條件從句可以放于句子前面，也可以放于后面。例：
Ifitrains，Iwon‘tgowithyou。
如果下雨我就不和你去了。
Iwon’tgowithyouifitrains。
