Warming up by discovering useful words and expressionsStep 3 Learning about grammar同位語從句講義及練習(xí) 一、理解同位語從句的含義，把握同位語從句的實質(zhì) 在主從復(fù)合句中作同位語的從句稱為同位語從句。同位語從句一般用that,whether，what, which, who,when, where, why, how 等詞引導(dǎo)，常放在fact,news,idea,truth,hope,problem,information,wish, promise, answer, evidence, report, explanation, suggestion, conclusion,等抽象名詞后面，說明該名詞的具體內(nèi)容。換言之，同位語從句和所修飾的名詞在內(nèi)容上為同一關(guān)系，對其內(nèi)容作進一步說明。 例：The news that they had won the game soon spread over the whole school.他們比賽獲勝的消息很快傳遍了整個學(xué)校。 析：they had won the game說明The news的全部內(nèi)容，因此該句為同位語從句。 二、正確運用同位語從句的引導(dǎo)詞，準確把握同位語從句 1.如同位語從句意義完整，應(yīng)用that引導(dǎo)同位語從句。（that 不充當(dāng)成分，只起連接作用） 例：The general gave the order that the soldiers should cross the river at once.將軍下達了戰(zhàn)士們立即過河的命令。 析：the soldiers should cross the river at once是the order的全部內(nèi)容，且意義完整，因此應(yīng)用that引導(dǎo)同位語從句。 2.如同位語從句意義不完整，需增加"是否"的含義，應(yīng)用whether引導(dǎo)同位語從句。（if不能引導(dǎo)同位語從句） 例：Well discuss the problem whether the sports meeting will be held on time.我們將討論運動會是否會如期舉行的問題。 析：the sports meeting will be held on time意義不完整，應(yīng)加"是否"的含義才能表達the problem的全部內(nèi)容，因此應(yīng)用whether引導(dǎo)同位語從句。 3.如同位語從句意義不完整，需增加"什么時候"、"什么地點"、"什么方式"等含義，應(yīng)用when,where,how等詞引導(dǎo)同位語從句。 例1：I have no idea when he will be back. 析：he will be back意義不完整，應(yīng)加"什么時候"的含義才能表達idea的全部內(nèi)容，因此應(yīng)用when引導(dǎo)同位語從句。 例2：I have no impression how he went home,perhaps by bike. 析：he went home意義不完整，應(yīng)加"如何"的含義才能表達impression的全部內(nèi)容，因此應(yīng)用how引導(dǎo)同位語從句。 4.當(dāng)主句的謂語較短，而同位語從句較長時，同位語從句常后肢。 如：The thought came to him that maybe the enemy had fled the city. 他突然想到敵人可能已經(jīng)逃出城了。 三、把握同位語從句和定語從句的區(qū)別，明確同位語從句和相似從句的界限 同位語從句和定語從句相似，都放在某一名詞或代詞后面，但同位語從句不同于定語從句。同位語從句對名詞加以補充說明，是名詞全部內(nèi)容的體現(xiàn)，且名詞和同位語從句的引導(dǎo)詞均不在從句中作成分；定語從句說明先行詞的性質(zhì)與特征，與先行詞是修飾與被修飾的關(guān)系，且名詞和定語從句的引導(dǎo)詞均在從句中作成分。 區(qū)分時可以在先行詞與與從句之間加一個系動詞be,使之構(gòu)成一個新句子，如果句子通順且符合邏輯，則為同位語從句，反之，則為定語從句。 如：The report that he was going to resign was false. 他將辭職的傳聞是假的。 因為the report was that he was going to resign 句意通順，所以，that he was going to resign 是同位語從句。 例1：Information has been put forward _ more middle school graduates will be admitted into universities.(NMETxx上海) A.while B.that C.when D.as 析：答案為B。more middle school graduates will be admitted into universities是Information的內(nèi)容，且Information不在從句中作成分，所以該句為同位語從句。應(yīng)將該句區(qū)別于： It is said that more middle school graduates will be admitted into universities，this is the information _ has been put forward. A.what B.that C.when D.as 析：答案為B。that has been put forward為information的修飾性定語，且information在從句中作主語，所以該句為定語從句。 例2：She heard a terrible noise,_ brought her heart into her mouth.(MET91) A.it B.which C.this D.that 析：答案為B。分析語境含義、句子結(jié)構(gòu)和句子成分可知，該句為非限制性定語從句，先行詞為a terrible noise，且它在從句中作主語。應(yīng)將該句區(qū)別于： I cant stand the terrible noise _ she is crying loudly. A.it B.which C.this D.that 析：答案為D。she is crying loudly是the terrible noise的內(nèi)容，且the terrible noise不在從句中作成分，所以該句為同位語從句。Step 4：Summing upSummarize the rules of the noun clause.1）定語從句對先行詞起修飾、限制的作用；同位語從句說明它前面的名詞的內(nèi)容。2）that在定語從句中擔(dān)任句子成分，是關(guān)系代詞。當(dāng)that 充當(dāng)定語從句的賓語時可時略；that 在同位語從句中不擔(dān)任句子成分，是從屬連詞，通常把你省略。 分層作業(yè)布置1.
