初三連詞教案

1、姓名學(xué)生姓名填寫時間2011-3-30學(xué)科英語年級初三教材版本人教版課題名稱中考語法之連詞第（）次課共（）課時上課時間2011教學(xué)目標(biāo)掌握各種的連詞的用法，中考這一考點(diǎn)的解題技巧教學(xué)重點(diǎn)各種的連詞的用法，中考這一考點(diǎn)的解題技巧教學(xué)過程 一、if作為連詞，引導(dǎo)條件狀語從句，它表示的意思是“假如”“如果”等。在復(fù)合句中如果主句用將來時，則if引導(dǎo)的狀語從句用一般現(xiàn)在時，主句用將來時。例如： 1. If itdoesntrain, we will go to the park next Sunday. 如果天不下雨，下周星期天我們將去公園。 2. If you ask him，he will hel

2、p you如果你求他，他將會幫助你。 二、if作為連詞還可以引導(dǎo)賓語從句。引導(dǎo)賓語從句時和whether意思相同。例如： 1. Lily asked if whether she liked it. 莉莉問她是否喜歡它。 2. She asked if whether they had a cotton one 她問是否他們有一件棉織的。3.I dont know if it will rain tomorrow. 三、用于虛擬語氣中，if從句中用過去式，表示不可能實(shí)現(xiàn)，大概不會實(shí)現(xiàn)或提出作為考慮的假定條件。例如： 1. If you were a bird, you could fly.假使

3、你是只鳥，你便會飛了。 2. If I asked him(if I were to ask him) for a loan，would he agree?如果我向他借貸，他會答應(yīng)嗎? 另外，if從句中用過去完成式，表示過去未實(shí)現(xiàn)的條件(例如由于不可能實(shí)現(xiàn)或某人之未能實(shí)行)。例如： 1. If they had started earlier，they would have arrivedin time要是他們早些動身，他們便可及時到達(dá)了。 2. If they had not started when they did，they would not be here now如果他們那時不動身，

4、現(xiàn)在他們就不會在此地了。 第三，在文學(xué)體栽中，if有時可省略，然后將主語與所用的限定動詞(尤其是were，had，should)倒置。例如： 1. Should it (=if it should)be necessary，I will go. 倘若有必要，我會去的。 2. Were I(=if I were) in your place，I would do the same 如果我處于你的位置，我也會這樣干的。 3. Had I(=if I had)known earlier，I would come如果我早一點(diǎn)知道，我就會來。四、if與其它一些介詞的連用。 首先，as與if連用，它的意思

5、是：“仿佛、好像”同樣引導(dǎo)從句。例如： 1. It isnt as if we are rich(We are not rich)我們不像富有的樣子。(即我們不富有) 2. It isnt as if he doesnt know the ruler(ieHe does know the rulers)他不像不懂規(guī)則的樣子。(即他懂得規(guī)則) 五.另外as if還可以引導(dǎo)感嘆句。例如： As if I would allow it!(ieI would certainly not allow it!)好像我會答應(yīng)似的!(我才不會答應(yīng)哩!) 其次, if與only連用。常表示愿望或一個未實(shí)現(xiàn)的條件

6、，尤其用于感嘆句中。例如： 1. If only he arrives in time!他若能及時到達(dá)就好了! 2. If only she would marry me!但愿她能嫁給我！ 3. If only she had known about it!（But she didnt know.） 她那時要是知道（但她不知道）這事就好了!一、連詞的定義 * 連接詞與詞、短語與短語、句子與句子的詞，叫連詞。例如：* It is neither too cold nor too hot in spring.（neithernor連接兩個詞）* You can read either in the

7、 morning or in the afternoon.（eitheror連接兩個短語）* Hu Lan was late yesterday because she woke up too late. （because連接兩個句子）二、連詞的種類和?？歼B詞的用法* 從連詞本身的含意及其所連接的成分的性質(zhì)來看，可分為兩類：并列連詞和從屬連詞。* 一）并列連詞。用來連接有并列關(guān)系的詞、短語或分句的連詞是并列連詞；并列連詞連接分句構(gòu)成并列句。（一） 常用來并列同類性質(zhì)的詞與詞、短語與短語的并列連詞and,or, neither.nor,either.or,not only.but also, b

8、oth.and：* 1. and 和，并且* My uncle lives and works in Shanghai. 我叔叔在上海居住和工作。* He's big and tall. 他很高大。* 2. or 或（非否定句中）、和（否定句中）* Are you a teacher or a student? 你是老師還是學(xué)生？* You can take some food or some money. 你可以帶點(diǎn)吃的或帶點(diǎn)錢。* I dont like reading or writing. 我既不喜歡讀，也不喜歡寫。* 3.either.or, 要么要么，或者或者*

9、neither.nor, 既不也不* both.and, 既又* not only.but also.不僅而且* You can come to see me either on Sunday or on Saturday. 你要么在周日來，要么在周六來。* I don't like its color, it is either too dark or too light. 我不喜歡它的顏色，不是太暗就是太淺。* The boy is both tall and fat. 那個男孩又高又胖。* My daughter can not only sing but also dance.

10、我的女兒不僅能唱，還會跳。*（二） 常見的并列分句構(gòu)成并列句的連詞有and，or，but，so* 1. or 否則 相當(dāng)于一個否定條件句。* Hurry up, or youll be late. 快點(diǎn)，否則你就要遲到了。* (If you don't hurry up, you'll be late.)* 2. and這樣的話，就會，相當(dāng)于一個肯定條件句* Study hard, and you can get good grades.努力學(xué)習(xí)，你就會取得高分。* (If you study hard, you can get good grades.)* 3. but 但是

11、，可是，而 前后分句是轉(zhuǎn)折關(guān)系* Mr Mott is very poor, but he feels happy. Mott先生很窮，但他感到快樂。* 4. so于是，因此 并列具有因果關(guān)系的兩個分句。* We wanted to learn the English songs, so we asked the teacher to teach us.* 我們想學(xué)英文歌，于是請老師教我們。 *（三） 從屬連詞。引導(dǎo)從句的連詞叫做從屬連詞，分連接代詞和連接副詞兩種。* 1. 引導(dǎo)賓語從句的有that, when, where, who, why, what, if, whether* 1).

12、that用于引導(dǎo)陳述句的賓語從句，可以省去，如：* She says that she likes watching TV very much.* 2). when, where, who, why, what等連接副詞連接由特殊疑問句轉(zhuǎn)化過來的賓語從句。如：* Do you know when the train arrives?* Can you tell me where you come from?* 3). if, whether連接有一般疑問句轉(zhuǎn)化過來的賓語從句。 * They are wondering if they can get the money back.* She a

13、sked the librarian whether she had to pay for the lost book.* 注：下列幾種情況下不能使用if來引導(dǎo)賓語從句。* 介詞后的賓語從句不能使用if 引導(dǎo)* Are you interested in whether she will come here?* 后跟or not時，不能使用if引導(dǎo)* Im not sure whether or not the shop is open.* 當(dāng)后跟動詞不定式時，不能使用if引導(dǎo)* Do you know whether to go to the Great Wall tomorrow?*2.

14、引導(dǎo)狀語從句的連詞有when，until，after, before, as soon as, since, for, although，if，because，so that，as if, sothat, while等。 * 1) 引導(dǎo)時間狀語從句的連詞有when，while, until，after, before, as soon as, since* 2) 引導(dǎo)條件狀語從句的連詞有if, unless* 3）引導(dǎo)原因狀語從句的連詞有because* 4）引導(dǎo)結(jié)果狀語從句的連詞有 so.that/suchthat* 5）引導(dǎo)比較狀語從句的連詞有than, asas* 【目標(biāo)導(dǎo)航】 * 中考
