⑴ 初二英語語法有哪些啊、

一、意義與構成
1. 意義:表示過去
1) 發生或已經完成的動作對現在造成影響或後果
2) 某一時間開始並一直持續到現在的動作或狀態
2. 基本構成:have/has+ done (過去分詞)
3. 句型
基本結構:主語+have/has+ done (過去分詞)
a. 肯定句:主語+have/has+ done (過去分詞)
b. 否定句:主語+have/has+not+ done (過去分詞)
c. 一般疑問句:Have/Has+主語+ done (過去分詞)
d. 特殊疑問句:特殊疑問詞+have/has+主語+ done過去分詞

二、過去分詞
與動詞的過去式一樣,動詞的過去分詞有規則動詞過去分詞和不規則動詞過去分詞兩種。
1. 規則動詞:規則動詞的過去分詞的構成規則與規則動詞的過去式的構成規則相同
1) 一般動詞,在詞尾直接加「 ed 」
如:work—worked—worked; play—played—played; enjoy—enjoyed—enjoyed.
2) 以「e」結尾的動詞,只在詞尾加「d 」
如:dance—danced—danced; live—lived—lived; place—placed—placed.
3) 以「輔音字母 + y 」結尾的動詞,將 「y」 變為 「i」 ,再加「ed」
注意:母音字母+y結尾的動詞的過去分詞的變法參見一般動詞。
如:carry—carried—carried; hurry—hurried—hurried; cry—cried—cried
4) 重讀閉音節結尾,末尾只有一個輔音字母,先雙寫這個輔音字母,再加「ed」
如:plan—planned—planned; stop—stopped—stopped; drop—dropped—dropped

2. 不規則動詞
不規則動詞的過去分詞有5種形式:
A-A-A 如:cost—cost—cost; cut—cut—cut; hit—hit—hit
A-B-B 如:bring—brought—brought; build—built—built; catch—caught—caught;
keep—kept—kept; sell—sold—sold; smell—smelt—smelt;
learn—learnt—learnt; say—said—said; meet—met—met;
make—made—made; leave—left—left
此類變化涉及到的動詞較多,需要同學們認真記憶。
A-B-C 如:begin—began—begun; blow—blew—blown; drive—drove—drive;
break—broke—broken; forget—forgot—forgotten; eat—ate—eaten;
take—took—taken; do—did—done
此類變化涉及到的動詞較多,需要同學們認真記憶。
A-A-B 如:beat—beat—beaten
A-B-A 如:come—came—come
不規則動詞的過去分詞變化規則多,但是還是有一定的規律所循,希望同學們多花心思,細心記下,這是使用完成時態的基礎。

三、用法
1. 現在完成時用來表示過去已發生過或完成的動作或狀態,但其結果卻和現在有聯系,也就是說,動
作或狀態發生在過去但它的影響現在還存在。
I have spent all of my money. 我花光了身上所有的錢。
(含義是:I don』t have any money now.)
Jane has laid the table. Jane已經把桌子擺好了。
(含義是:We can sit and have dinner.)
Michael has been ill. Michael病了。
(含義是:He can』t come to school.)
He has returned from abroad. 他已經從國外回來了。
(含義是:He』s at home now.)

2. 現在完成時可以用來表示發生在過去某一時刻的,持續到現在的情況,常與for(+時間段),
since(+時間點)連用。
Mary has been ill for three days. Mary已經病了三天了。
I have lived here since 1998. 我從1998年起一直住在這。
I have been a teacher for 10 years. 我當老師已經10年了。
注意:點動詞(buy, die, join, finish等)不能直接與for, since 連用,需要改變動詞。
1) have代替buy
I have bought new car. 他買了輛新車。(含義:他自己有車,不用搭別人車等。)
I have had this bike for almost 7 years. 我買這輛自行車七年了。
2) 用keep或have代替borrow
He has kept the book for a long time. 他借這書好長時間了。
3) 用be in替代come to/ join/ move to等
How long have you been in America? 你來美國多久了?
4) 用be+副詞 替代start/ get up/ return to/go back to
The show has been on for half an hour. Hurry up!
演出已經開始了半個小時了。快點!
I』ve been up for an hour, but I still feel sleepy.
我起床已經一個小時了,但是我還是覺得很困。
He has been back to his hometown for a year, but he』s still missing the life in the
city.
他回到故鄉都一年了,但是他還是很懷念城市生活。
總之,後加時間的完成時表達中,都表達一個動作所延續的時間,而點動詞只表達那一動作,動作之後所處的狀態,應該用相應的狀態詞來表達,如come是「來」的意思,而來之後的日子都是「在…」因為不能用come表達,應該用be in…來表達,意為「一直處於…」。

3. 現在完成時的時間狀語
現在完成時屬於現在時范圍,故不能和過去的時間狀語連用。如:yesterday, last Sunday,
in1990, three years ago等。但是,在強調動作產生的後果和影響時,可以和一些表示不確定的時
間狀語連用。
如:I have finished my homework yesterday. (×)
I finished my homework yesterday. (√)
1)副詞already和yet
already一般用於肯定句中,yet一般用於否定句和疑問句中。
如:I』ve already slept for 12 hours but I』m still feeling tired.
我都睡了12個小時了可是我還是很累。
I haven』t finished working yet.
我還沒有完成工作。
Have you found your lost cat yet?
你找到你丟了的小貓了嗎?
2)ever和never
多用於否定或疑問句中,表示「曾經」或「從未」。
如:---Have you ever been to the Great Wall? 你曾經去過長城嗎?
---No, I haven』t. I have never been to the Great Wall. 沒有。我從未去過長城。
3)用表示到說話為止的過去時間狀語,如:just, before, up to now, the past few years等。
如:I have just finished my paper. 我才寫完我的論文。
I』ve dream about that before. 我以前夢到過那個情景。
Up to now, he has got 3 gold medals in the Olympic Games.
到現在為止,他已經在奧運會中取得了三塊金牌。
He has been there three times the last few days.
近幾年他去過那裡三次了。
4)用包括「現在」在內的時間狀語,如:now, today, this morning (month, year, term)等。
如:---Have you met him today?
---No, I haven't.
---今天你見過他嗎?---沒有。
How many times have you been there this year?
今年你去過那裡多少次?

二. 完形填空特點及解題思路
(一)題型分類與特點
完形填空試題是在給出的一篇短文中有目的地拿掉若干個詞,留下一些空格,要求考生藉助短文保留的部分,從所給的短文整體出發,在正確理解短文意思的基礎上,根據句子和句子間的內在聯系、詞的用法和習慣搭配等,用適當的詞或詞語填空,使補全後的短文意思通順、前後連貫、結構完整。這種題型測試的內容從形式上看是單詞或短語的填空,但它必須注意到短文中上、下文意思連貫、詞語搭配和語法結構正確,所以在空格上所填的詞必須符合語義適用和語法正確兩條原則,只考慮某一側面都可能導致錯誤。中考中完形填空試題的基本題型分兩類:完形填空選擇題和完形填空題。
1. 完形填空選擇題:該題型的特點是將一篇短文中若干詞語抽掉留下空格,對每一空格提供若干個選擇項,要求考生通讀短文後,在理解短文意思的基礎上,運用所學的詞彙、句型、語法等語言知識,從所提供的備選項中選出一個最佳答案,使短文內容完整正確。中考完形填空主要以這種題型為主。它所給的短文一般與初中英語教材難易程度相當,字數在150-200個單詞之內,多數設置10個左右空格,所設考點涉及詞彙、語法及對短文內容的理解。短文的第一句一般不設空,以期提供一個語境,對每一空格設置的選項基本都屬於相同或對等的詞類,給判定選擇帶來一定的干擾,側重考查了考生准確運用詞彙的能力及對短文的整體理解和邏輯推理能力。
2. 選詞填空題:該題型的特點是把抽出的詞打亂順序,不按原文順序排列,放在短文前面或後面的方框內,有時還增加幾個文外的詞,要求考生從中選出適當的詞以正確的形式填入短文空格內。
(A)
Jack wanted to ask for two days off, 1 he had only learnt the phrase (短語)「have a day off」. He 2 , then he had an idea. 「Grandmother is ill. May I have a day off, 3 ? 」he asked the teacher. 「Of course, you can. 」replied (答復)the teacher at once. After a while, the boy came to 4 at the teacher』s door. 「May I have a day off 5 ? 」The teacher was very surprised, 「Didn』t you 6 it just now? 」「Yes, sir. But I can』t be here 7 , either. 」The teacher understood him and could not help 8 . Then he said with a smile, 「Why didn』t you say『May I have two days off? 』」The boy answered quickly 9 a loud voice. 「But you only 10 us『have a day off! 』」
( )1. A. but B. and C. or D. for

( )8. A. laugh B. to laugh C. laughed D. laughing
( )9. A. with B. on C. in D. by
( )10. A. teach B. taught C. are teaching D. were teaching

(B)
請根據內容從所給的15個單詞中選出最恰當的10個填入空白處,使短文完整,有些詞要根據需要作適當的詞形變化。
than, so, tell, us, them, report, beause, love, composition, understand, to, that, much, for, what
A generation gap (代溝)has become a serious problem. I read a _______(1)about it in the newspaper. Some children have killed _______(2)after quarrels (爭吵)with parents. I think this is _______(3)they don』t have a good talk with each other. Parents now spend _______(4)time in the office. _______(5)they don』t have much time to stay with their children. As time passes, they both feel _______(6)they don』t have the same topics(話題)to talk about. I want to _______(7)parents to be more with your children, get to know them and understand them. And for children, show your feeling _______(8)your parents. They are the people who _______(9)you. So tell them your thoughts (想法). In this way, you can have a better _______(10)of each other.

完形填空選擇題的一般解題思路是:
1. 跳過空格、通讀全文、把握大意。先跳過空格,通讀試題所給的要完形填空的短文,獲得整體印象,做到弄清文脈、抓住主旨,較好地把握短文大意。要在閱讀理解短文意思的基礎上才開始判定選擇,切忌倉促下筆。
2. 結合選項、綜合考慮、初定答案。在理解全文意思的基礎上,再結合所給備選項細讀全文,聯繫上、下文內容,注意從上、下文的語法結構和詞語搭配及從選擇項中尋找解題的提示,以詞、句的意義為先,再從分析句子結構入手,根據短文意思、語法規則、詞語固定搭配等進行綜合考慮,對備選項逐一進行分析、比較和篩選,排除干擾項、初步選定答案。
3. 瞻前顧後、先易後難、各個擊破。動筆時要瞻前顧後、通篇考慮、先易後難。對比較明顯直接的、自己最有把握的答案先做,一下子不能確定答案的,先跳過這一空格,繼續往下做,最後回過頭來再集中精力解決難點。這時可結合已確定答案的選項再讀一遍短文,隨著對短文理解的深入,可以降低試題的難度,提高選擇的正確率。
4. 復讀全文、逐空驗證、彌補疏漏。完成各道題選擇後,把所選的答案代入原文,再把全文通讀一篇,逐空認真復查。看所選定的答案是否使短文意思前後連貫、順理成章,語法結構是否正確,是否符合習慣表達法。如發現錯誤答案或有疑問的,應再次推敲、反復斟酌、做出修正。
完形填空試題的一般解題思路是:
1. 跳過空格、通讀短文、了解大意。解題時先跳過空格,通讀完形填空的短文,了解全篇的內容和要旨。要重視首句,善於以首句的時態、語氣為立足點,理清文脈,推測全文主題及大意。
2. 復讀短文、確定語義、判斷詞形。把握短文大意後再認真復讀短文,利用上下文的語境,結合所學過的知識,先確定空格處所需詞語的意義,再根據空格在句子中的位置,判斷其在句中充當的成分,從而確定所填詞的詞性,再依據詞語搭配和語法規則,判斷所填的詞的正確形式。
3. 三讀短文、上下參照、驗證答案。在短文的每一空白處填上一個詞後,將完成的短文再細讀一遍,上下參照,連貫思考。把所填的答案放入短文中進行檢驗,可從上、下文內容是否協調一致、順理成章,語法結構是否正確無誤等進行綜合驗證,凡有疑問必須重新推敲考慮。

⑶ 初二的重要英語語法有哪些

反義疑問句(The Disjunctive Question)又叫附加疑問句。它表示提問人的看法,沒有把握,需要對方證實。反義疑問句由兩部分組成:前一部分是一個陳述句,後一部分是一個簡短的疑問句,兩部分的人稱時態應保持一致。

1. 陳述部分肯定式+疑問部分否定式

2. 陳述部分否定式+疑問部分肯定式

They work hare, don』t they?

She was ill yesterday, wasn』t she?

You didn』t go, did you?

He can』t ride a bike, can he?

請注意以下句型的反義疑問句的用法:

1. 當陳述部分的主語是I , everyone, everything, nobody 時,後面的疑問句應表示為:

I am a student, aren』t I

Everyone is in the classroom, aren』t they?

Everything begins to grow in spring, doesn』t it?

Nobody will go, will they?

2. 當陳述部分有never,seldom, hardly,few,little,barely, scarcely, nothing 等否定詞時,後面的疑問句則表示為:

There are few apples in the basket, are there?

He can hardly swim, can he?

They seldom come late, do they?

3. 當陳述部分是I think 加從句時,疑問句應和從句的人稱時態保持一致。

I think chickens can swim, can』t they?

I think Lucy is a good girl, isn』t she?

I didn't think he was happy, was he?

4. 陳述部分有had better 時,疑問句應用hadn』t開頭:

you』d better get up early, hadn』t you?

5. 當陳述部分是祈使句時,疑問句要根據語氣來表達:

Let』s go out for a walk, shall we?

Let us go our for a walk, will you?

Turn on the radio, will you?

6. 反義疑問句的回答用yes, no, 但是,當陳述部分是否定形式時,回答要按事實。如:

They don』t work hard, do they? 他們不太努力工作,是嗎?

Yes, they do. 不, 他們工作努力。/No, they don』t. 對, 他們工作不努力。

一、反意疑問句的一般情況
1.當陳述部分的主語是:等everyone, everybody, someone, no one, nobody, somebody合成代詞時,附加疑問句的主語非正式文體中往往they用。(也可以按語法一致原則用單數。)

2.當陳述部分以one不定代詞做主語時,附加問句的主語在正式常場用one,非正式場合用he。

3.當陳述部分的主語是不定式、動名詞、從句、this或that,附加疑問句的主語用it。(是those, these則用they)

4.當陳述部分的主語是表示物的不定代詞everything, anything, nothing等,附加問句的主語用 it。

5.陳述部分帶有否定詞或半否定詞,例如:never, hardly, scarcely, seldom, no, none, no one, rarely, nowhere, nothing, nobody, few, little等,附加疑問句的動詞要用肯定形式。

6.如果陳述部分中的否定詞僅帶有否定的前綴或後綴,那麼該陳述句應作肯定句處理,附加疑問句應用否定形式。

二、常見句型的反意疑問句
7.當陳述部分是there be 存在句型時,附加疑問句的主語也用there。

8.感嘆句的附加疑問句,其謂語要求用否定句。

9.祈使句後面的附加疑問句問題
A) 祈使句是否定形式,附加疑問句只能用will you。
B) 祈使句是肯定形式,附加疑問句用肯定、否定均可。
C) Let開頭的祈使句要注意:
1.Let』s 在意義上包含談話的對方在內,表示提出建議或徵求對方意見,其反意疑問句往往用shall we。
2. Let us 在意義上一般不包含談話的對方在內,表示請求對方允許做某事的含義,let 有allow的意思。附加疑問部分用will you。
3. Let me 開頭表示請求,附加疑問句用will you,或用may I。

三、復合句的反意疑問句
10.當陳述部分是一個(帶that引導賓語從句的)主從復合句時,附加疑問句的主謂要和主句的主謂保持對應關系。但是,當陳述部分的主語是:I suppose, I think, I believe, I imagine, I expect等結構時,附加疑問句的主語和謂語要和從句的主語,謂語保持一致關系。而且要注意到否定的轉移問題。

11.當陳述部分是I』m sure that,;we are sure;I』m afraid that;We are sure that;I feel sure that 等後面跟賓語從句時,反意疑問句與後面的賓語從句一致。

12.當陳述部分是並列句時,附加疑問句的主謂語要和離它最近的句子的主謂保持對應關系。

四、關於情態動詞的反意疑問句
13.陳述部分中有have一詞,且表示「所有」含義時,附加疑問句部分既可用have也可用do。

14.陳述部分中有have to,附加疑問句部分用do。

15.含有ought to 的反意疑問句,陳述部分是肯定的,疑問部分用shouldn't / oughtn't +主語。
He ought to know what to do, oughtn't he? / shouldn't he?

16.陳述部分有used to,附加疑問句部分可用used 也可以用did 。

17.陳述部分有needn』t時,附加疑問句部分用need但有時也可用must。

18. 陳述部分有must,且表示「必須」時,附加疑問句部分用mustn』t,如果表示「必要」則用needn』t。

19.陳述部分中是mustn』t表示「禁止」時,附加疑問句部分用must。
陳述部分中的must表示「一定」、「想必」等推測意義時,附加疑問句部分而是根據陳述部分的謂語動詞或其助動詞來定。

20.陳述部分是I wish, 表示詢問或徵求意見,附加疑問部分用may I。

21.弄清陳述句中的』d rather = would rather;』d better = had better附加疑問句部分前者用would,後者用had。

其它特殊結構的反意疑問句
22.陳述部分的主語是each of...結構時,附加疑問句在強調整體時用they,當作個別時用he。

23.陳述部分有neither...nor...(either...or...)做並列主語,附加疑問部分根據其實際邏輯意義而定。
Neither you nor I am engineer, are we?

24.陳述部分是:I』m ....結構,附加疑問句一般用aren』t I?

28. 帶情態動詞dare或need的反意疑問句,疑問部分常用 need (dare ) +主語。
We need not do it again, need we ?
He dare not say so, dare you?
當dare, need 為實義動詞時,疑問部分用助動詞do + 主語。
She doesn't dare to go home alone, does sh

⑷ 初中八年級英語所有語法

現在完成時
1.構成
現在完成時是由助動詞 have(has)+動詞的過去分詞構成。助動詞說明該謂語是屬於現在時范圍。它和主語的人稱、數要保持一致。過去分詞是主要的謂語動詞,說明句子的意義。
2.用法
(1)表示動作發生在過去某個不確定的時間,但對現在留下了某種影響和結果。常被just, already, yet 等副詞修飾。常與非延續性動詞連用。 如:
-Have you had lunch yet? -Yes, I have. I've just had it. 你(已經)吃午飯了嗎? 我剛剛吃過。(現在我不餓了)
(2)表示從過去某一時刻開始一直持續到現在的動作或狀態。這個動作可能剛停止,可能仍然在進行。常用延續性動詞,常帶有for和since(自從)等表示一段時間的狀語。
如:He has taught here since 1981. 他自1981年就在這兒教書。(可能還要繼續教)
I haven't seen her for four years. 我有四年沒見到她了。
(3)表示說話前發生過一次或多次的動作,現在成為一種經驗,一般譯為漢語「過」,常帶有twice, ever, never, three times等時間狀語。
如: I have been to Beijing twice. 我去過北京二次。
3.結構
1)陳述句結構:主語+have( has)(not)+過去分詞+其它。have not=haven』t has not= hasn』t.
2) 一般疑問句結構:Have( Has )+主語+過去分詞+其它?
3) 特殊疑問句:特殊疑問詞+have(has) +主語+ 過去分詞+其它?
e.g. He has already finished his homework.
He hasn』t finished his homework yet.
Has he finished his homework yet? --Yes, he has. / No, he hasn』t. / No, not yet.
4.現在完成時的時間狀語
1)現在完成時屬於現在時范圍,故不能和過去的時間狀語連用。如: yesterday, last Sunday, in1990, three years ago等。但是,在強調動作產生的後果和影響時,可以和一些表示不確定的時間狀語連用。
a. 用副詞already和yet。already一般用於肯定句中,yet一般用於否定句和 疑問句中。如:We have already finished our homework.我們已完成作業了。
They haven't finished their homework yet.他們還沒有完成作業。
b. 用ever 和never。多用於否定或疑問句中,表示「曾經」或「從未「等。 如:-Have you ever been to the Great Wall?你曾經去過長城嗎?
-I have never been to the Great Wall.我從未去過長城。 c. 用表示到說話為止的過去時間狀語,如just(剛剛), before(以前), up to now(直到現在)/ until now, in the past (few years/ three days 等), so far (迄今為止) recently 等。 例如:I have seen her before, but I can not remember where. 我以前見過她,但記不起在哪裡見過。
He has been there three times the last few days. 近幾年他去過那裡三次了。 d.用包括「現在」在內的時間狀語,如:today, this morning (month ,year, term等.例如:-Have you met him today? - No, I haven't. 今天你見過他嗎?我沒有。
How many times have you been there this year? 今年你去過那裡多少次?
2) 現在完成時可以和帶有since或for等表示「一段時間」的狀語連用,表示動作或狀態從某一時刻開始,一直持續到現在。如:I haven't seen him for two years. 但是,像come, arrive, buy等終止性動詞不能與表示「一段時間」的狀語連用。要用,必須改為「be(在)」等延續性動詞來表述。現歸納總結一下由非延續性動詞到延續性動詞的轉換:
arrive → be here begin (start) → be on die →be dead come back → be back leave → be away fall ill (sick, asleep) → be ill (sick, asleep) go out →be out finish →be over put on →wear 或be on get up →be up join →be in / be a member of… open → be open close →be closed go to school→ be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study → study come to work→ work
如:He has been a soldier for three years.他參軍三年了。或He has been in the army for there years. 不可以說He has joined the army for there years.
His father has been dead for two years.他父親去世二年了。(不可以說has died)
The film has been on for ten minutes.電影已開始十分鍾了。(不可以說has begun)
We have studied English for three years. (不可以說have begun) 我們(開始)學英語已三年了。
5. 現在完成時和一般過去時的區別
現在完成時和一般過去時都表示在過去完成的動作。但現在完成時強調的是這一動作與現在的關系。如對現在產生的結果或影響等,而一般過去時只表示動作在過去某一時刻發生,不表示和現在的關系。試比較:
I have lost my new book. 我把新書丟了。(現在還未找到)
I lost my new book yesterday. 我昨天把新書丟了。(昨天丟的,現在找到與否沒說明)
6.幾點注意事項 (1)have been(to)與have gone( to)的區別:have been(to) 表示「去過某地(現在已經回來了)」,可用於各人稱;have gone(to) 表示「去某地了(說話時某人不在當地)」,常用於第 三人稱,前者可與once ,never, several times等連用,後者則不能。如:They have been to Beijing twice.他們去過北京兩次。 He has gone to Beijing . 他去北京了。 (2)「It is或has been + 一段時間+ since引導的時間狀語從句」表示「某人干某事已經多長時間了」。since從句的謂語要用非延續性動詞 若動詞延續,則譯成相反的意思。如:It is two years since his father died. =His father has been dead for two years.他父親去世已有三年了。 It is two years since his father lived here. 他爸爸不住這兒已有三年了。 (3)終止性動詞現在完成時的否定式,已變成一種可以延續的狀態,因此可以和表示一段時間的狀語連用。如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。 (4).提問for短語或since狀語用how long。
(5).完成時的否定形式與比較級連用表達最高級含義。如:
I have never seen a better film.我從未看過一部更好的電影。(這部最好)
註:否定式與比較級連用表示最高級含義不一定用於完成時態。如:
--- What about going fishing? --- I can』t agree more.(我再同意不過了哦)
.語法—直接引語變間接引語(多數情況下變為賓語 從句)
(1). 直接引語如果是陳述句,變為間接引語時,用連詞that 引導(口語中可以省略引導詞)賓語從句。把下列句子變為間接引語或直接引語:
a. 「I』ll visit my aunt tomorrow.」 Lily said. ____________________________.
b. Our teacher often say to us,」 It』s important to finish your homework.」
_______________________________________________________
c. They said they would meet at 9:00 p.m. that night.
「_______________________________________.」they said.
d. Lana said that she wasn』t mad at Marcia anymore.
Lana said』」_______________________________.」
(2). 直接引語如果是一般疑問句,變為間接引語時,變為由連詞if 或whether引導的賓語從句。把下列句子變為間接引語或直接引語:
a. 「Will you have a surprise party for me?」 he asked me.
_______________________________________________
b. She asked Tom,」 Can you help me?」 ___________________________ c. He asked me if I knew who killed the cat.
He asked ,」__________________________________?」
(3). 直接引語如果是特殊疑問句,變為間接引語時,疑問詞不變,賓語從句用陳述語序。把下列句子變為間接引語或直接引語:

______________________________________________.
b. 「When will you find out the time?」 she asked me.
______________________________________________.
c. 「What』s the matter with you, Alice?」 he asked.
_____________________________________
d. They asked me where my friends were.
____________________________________________
(4).直接引語如果是肯定型祈使句,變為間接引語時,謂語變為tell sb. to do 或ask sb. to do 等句式。把下列句子變為間接引語或直接引語:
a. 「Make sure the door is closed,」 she said to her little son.
____________________________________________________.
b. 「Tell me the news, please.」 Li Hui said to me.
____________________________________________________.

2. if 條件句 在一般將來時的句子里(指主句),時間狀語從句、條件狀語從句等的謂語動詞用一般現在時代替將來時。當主句含有情態動詞或主句為祈使句時,從句也用一般現在時。如:You must pay for it if you lose it.

附加疑問句
附加疑問句由「陳述句 + 附加疑問句」兩部分構成。一般有兩種形式:前肯後否或前否後肯。對附加疑問部分應注意以下幾點: 1)主語只能用人稱代詞;2)附加疑問句的not必須與(be /助/情)縮寫;3)附加疑問句的時態必須與陳述部分的時態一致。
Tom is a worker, isn』t Tom? (改錯) _______ You can swim, can not you? ( 改錯) ______
特別注意以下幾種反意疑問句
1.陳述部分含否定意味的詞如few,little,never,nothing,nobody,no,hardly,none,seldom等時,附加疑問句應使用肯定形式;但如果陳述句部分含有un-, in-, im-, dis-等否定前綴構成的派生詞時,該陳述句部分仍做肯定處理,疑問部分用否定形式。

6.陳述部分是there be結構時,應用be there?結構來完成。 There』s little water, _________?
7..陳述部分含that引導的賓語從句時,疑問部分通常與主句一致。但當主句陳述部分是」I / We think (believe, suppose) +賓語從句」時,附加問句應與從句一致。I』m sure + 賓語從句也是如此
1).She said I did it, _________? 2)We don』t think you are right,________?
3) I』m sure you』ll help me, ____________?
8.如果陳述部分是I am… , 附加疑問部分為aren』t I? I am older than you, __________?

10.陳述部分是感嘆句,附加問句的人稱代詞應與主語一致,疑問部分用否定形式。 What a kind girl, isn』t she? What a fine day, ___________?
11.the+形容詞表示一類人,其附加疑問句主語用復數代詞。 The poor had no right to speak at that time, did they?
12. 由neither…nor,either… or , not only…but also , both…and , not…but,…or…, …and…等連接的並列主語,附加疑問部分用復數。

13.當陳述部分含有have to時,附加疑問部分的助動詞應根據have 的變化,分別用don』t, doesn』t, didn』t。 He has to take your advice, doesn』t he?
14.當陳述部分的主語是從句、不定式、動名詞或片語時,附加疑問部分的主語通常用it。 What he said at the meeting is very important, isn』t it? Swimming in rivers is a good sport, _____________?
15.當陳述部分含有wish時,附加疑問部分的助動詞用may。I wish to use your computer, may I?
16. 當陳述部分的謂語是「used to+動詞原形(過去常常干某事)」時,疑問部分用「didn』t+主語」或「usedn』t +主語」。 He used to live in London, didn』t he? / usedn』t he?
