period 4 grammar學(xué)習(xí)目標(biāo) 1.復(fù)習(xí)狀語(yǔ)從句的用法 2.狀語(yǔ)從句中連詞的選用 學(xué)習(xí)重點(diǎn)：掌握狀語(yǔ)從句的用法學(xué)習(xí)難點(diǎn)：如何確定狀語(yǔ)從句中的連詞課前預(yù)習(xí)：finish activities 15 about adverbial clauses on pages 4445.使用說(shuō)明與學(xué)法指導(dǎo)：借助預(yù)習(xí)案中的語(yǔ)法講解，復(fù)習(xí)狀語(yǔ)從句的用法，完成時(shí)間15分鐘。教材助讀：i. 觀察教材44頁(yè)上 activity 1中的例句，找出連詞，并結(jié)合已學(xué)的狀語(yǔ)從句知識(shí)完成下列表格。一、狀語(yǔ)從句考查要點(diǎn)簡(jiǎn)述。狀語(yǔ)從句主要用來(lái)修飾主句或主句的謂語(yǔ)。一般可分為九大類(lèi),分別表示時(shí)間、地點(diǎn)、原因、目的、結(jié)果、條件、讓步、比較和方式。盡管種類(lèi)較多,但由于狀語(yǔ)從句與漢語(yǔ)結(jié)構(gòu)和用法相似,所以理解和掌握它并不難。狀語(yǔ)從句的關(guān)鍵是要掌握引導(dǎo)不同狀語(yǔ)從句的常用連接詞和特殊的連接詞即考點(diǎn)。1、時(shí)間狀語(yǔ)從句（1）as、when、while用法一覽表。類(lèi)別作 用例 句asas 表示“當(dāng)?shù)臅r(shí)候”，往往和 when/ while 通用，但它著重強(qiáng)調(diào)主句與從句的動(dòng)作或事情同時(shí)或幾乎同時(shí)發(fā)生。1.she came up as i was cooking.( 同時(shí) )2.the runners started as the gun went off.( 幾乎同時(shí) )whenwhen (at or during the time that )既可以表示在某一點(diǎn)的時(shí)候，又可表示在某一段時(shí)間內(nèi)，主句與從句的動(dòng)作或事情可以同時(shí)發(fā)生也可以先后發(fā)生。1.it was raining when we arrived.( 指時(shí)間點(diǎn) ) 2.when we were at school, we went to the library every day.( 在一段時(shí)間內(nèi) )whilewhile意思是“當(dāng)?shù)臅r(shí)候”或“在某一段時(shí)間里”。主句中的動(dòng)作或事情在從句中的動(dòng)作或事情的進(jìn)展過(guò)程中發(fā)生，從句中的動(dòng)詞一般要用延續(xù)性動(dòng)詞。在when 表示 a period of time 時(shí)，兩者可以互換。1.please dont talk so loud while others are working. 2.he fell asleep while/ when reading. 3.strike while the iron is hot.( 用 as 或 when 不可，這里的 while 意思是“趁” ) （2）引導(dǎo)時(shí)間狀語(yǔ)從句的連接詞除上述外還有：till, not until , until, before, sincedont get off the bus until it has stopped.he waited for his father until(till)it was twelve oclock.it will be five years before he returns from england.hardly / scarcely when, no sooner than, as soon as once表示“一就”as soon as i have finished it , ill give yu a call.once you show any fear, he will attack you.we had hardly got / hardly had we got into the country when itbegan to rain.no sooner had he arrived / he had no sooner arrived than she started complaining.directly, immediately, the moment, the minute that 一就he made for the door directly he heard the knock.each time, every time, by the timeeach time he came to my city, he would call on me.注意：表示未來(lái)情況，主句用將來(lái)時(shí)，從句用現(xiàn)在時(shí)。2、讓步狀語(yǔ)從句 （1）although與though可以引導(dǎo)讓步狀語(yǔ)從句，不能與but連用，但可以與yet連用。although they are poor,(yet)they are warm-hearted.（2）even if或even though引導(dǎo)讓步狀語(yǔ)從句，表示“即使”，“縱然”，用來(lái)使人注意下文所強(qiáng)調(diào)內(nèi)容的性質(zhì)。ill get there even if(though)i have to sell my house to get enough money to go by air.（3）no matter后接上who、what、where、how等疑問(wèn)詞，也可以在這類(lèi)疑問(wèn)詞后面加上ever構(gòu)成whoever、whatever、wherever、however等。 dont trust him, no matter what / whatever he says.whoever breaks the law will be published.no matter how hard the work is, youd better try to do it well.（4）as也可以引導(dǎo)讓步狀語(yǔ)從句。要用倒裝。 child as(though)he is, he knows a lot.much as i like it, i wont buy.try as he would, he couldnt lift the heavy box.3、原因狀語(yǔ)從句：because, for, as, since, now that項(xiàng)目 區(qū)別位置內(nèi)涵語(yǔ)氣能否回答whybecause因?yàn)橹骶淝盎蚝笾苯拥囊蚬P(guān)系強(qiáng)能as由于 :主句前或后雙方都知道的原因弱 不能since/ now that既然主句前 for因?yàn)椋ú⒘羞B詞）主句后推斷的因果關(guān)系下列情況下只能使用because:在回答why的問(wèn)句時(shí)；在用于強(qiáng)調(diào)句型時(shí)；被not所否定時(shí)。例如： my friends dislike me because im handsome and successful.now that everybody has come, lets begin our conference.the higher income tax is harmful in that it may discourage people from trying to earn more.considering that he is no more than 12 years old, his height of 1.80 m is quite remarkable.4、地點(diǎn)狀語(yǔ)從句：where, wherevermake a mark wherever you have any questions.we will go where the party directs us.5、目的狀語(yǔ)從句：that, so that, in order that注意：目的狀語(yǔ)從句的謂語(yǔ)動(dòng)詞常與情態(tài)動(dòng)詞連用，否則可能是結(jié)果狀語(yǔ)從句。不可置于句首。特殊引導(dǎo)詞:lest, in case, for fear that,in the hope that, for the purpose that, to the end thatthe boss asked the secretary to hurry up with the letters so that he could sign them.the teacher raised his voice on purpose that the students in the back could hear more clearly.6、結(jié)果狀語(yǔ)從句：that, so that, so that, such that 注意：so + 形容詞/副詞 + that從句；such +名詞 + that從句。例如：he got up so early that he caught the first bus.its such a good chance that we must not miss it.to such an degree was he excited that he couldnt sleep last night.7、方式狀語(yǔ)從句：as, as if(though)ill do as i am told to.it looks as if it is going to rain.8.比較狀語(yǔ)從句：than, asshe is as bad-tempered as her mother.the house is three times as big as ours.the more you exercise, the healthier you will be.9、條件狀語(yǔ)從句：if, unless, so (as) long as, in case, once, a far as, on condition that.注意if與unless的區(qū)別：不能用and連接兩個(gè)unless從句，即不能有 unless ,and unless 。但if not and if not卻不受此限。 you wont lose your weight unless you eat less and unless you exercise more.()但可以說(shuō) unless you eat less and exercise more.well start our project if the president agrees.you will certainly succeed so long as you keep on trying.provided that there is no opposition, we shall hold the meeting here.10、注意狀語(yǔ)從句中從句的省略現(xiàn)象（1）連接詞 + 過(guò)去分詞dont speak until spoken to.pressure can be incrased when needed.unless repaired, the washing machine is no use.（2）連詞 +現(xiàn)在分詞look out while crossing the street.（3）連詞 + 形容詞/其他常見(jiàn)的有it necessary、if possible、when necessary、if any等。examples：(1) i dont think ill need any money but ill bring some _.(nmet 2000)a. as last b. in case c. once again d. in time解析：答案為b。句意為“帶些錢(qián)以防萬(wàn)一”，只能選擇in case。引導(dǎo)的條件狀語(yǔ)從句，后面省略了i should need it。(2) the wto cant live up to its name _ it doesnt include a country that is home to one fifth of mankind.（nmet 2000）a. as long as b. while c. if d. even though解析：答案為c。本題考查狀語(yǔ)從句的用法。句意為“假如世貿(mào)組織不包括占世界人口五分之一的中國(guó)的話，那它就名不副實(shí)”。as long as語(yǔ)氣過(guò)于強(qiáng)烈，while和even though不符合句意。(3) someone called me up in the middle of the night, but they hung up_i could answer the phone.(nmet 2000)a. as b. since c. before d. until解析：答案為c。題意為：半夜里有人打來(lái)電話，我沒(méi)來(lái)得及就掛了。but暗示在接話前就掛了。課內(nèi)探究：質(zhì)疑解疑，合作探究ii.practice review of adverbial
