【正文】 e you this ，他說他今天下午不能來看你了。例如：The thought came to her that maybe she had left the door open when she left 。二、同位語從句前名詞的數(shù)同位語從句前的名詞通常用單數(shù)形式，并且往往帶有限定詞(word除外)加以修飾。Word came that China launched its first manned spaceship on Oct 15，中國于2003年10月15日首次成功發(fā)射了載人飛船。例如：They were all very much worried over the fact that you were ，他們都很焦慮。We haven’t yet settled the question where we are going to spend our summer 。例如：We have some doubt whether they can plete the task on 。同位語從句：that有些名詞的后面可以接that引導(dǎo)的同位語從句：We came to the decision that we must act at ：我們必須立即行動。There was little hope that he would 。He hasn’t made the decision whether he will go 。同位語從句：whatwhat可以引導(dǎo)同位語從句，而定語從句不能用what作為引導(dǎo)詞I have no idea what he is doing 。同位語從句：who等who，whom，which，when，where，why用來引導(dǎo)同位語從句The question who should do the work requires ，這個問題需要考慮。四、同位語從句的語氣在suggestion，advice，request，order等意為“建議；命令；要求”的名詞后，同位語從句中的謂語動詞通常用“should +動詞原形”的虛擬語氣結(jié)構(gòu)，句中的should可以省略。The suggestion came from the chairman that the new rule(should)be 。五、同位語從句與定語從句的用法區(qū)別區(qū)別(1)同位語從句和先行詞是同等的關(guān)系；而定語從句是用來修飾先行詞，是從屬的關(guān)系。區(qū)別(3)whether，what，how可以用來引導(dǎo)同位語從句；而它們不能用來引導(dǎo)定語從句。who，whom，which，when，where，why用來引導(dǎo)定語從句時對應(yīng)性很強，如：先行詞是“人”，引導(dǎo)詞用“who”等，而它們引導(dǎo)同位語從句是先行詞通常是“question，idea，doubt等”。例2：I have no impression how he went home，perhaps by ：he went home意義不完整，應(yīng)加“如何”的含義才能表達(dá)impression的全部內(nèi)容，因此應(yīng)用how引導(dǎo)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 析： 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。應(yīng)將該句區(qū)別于：I can’t stand the terrible noise ____ she is crying 析： 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。一、完全倒裝（主謂倒裝）是指把謂語全部提到主語的前面。這種句子中的謂語動詞通常是不及物動詞。Here he es./ Here it out , in , up ,away , down 等副詞，句子要完全倒裝。如果是人稱代詞，也不能使用倒裝結(jié)構(gòu)。注意，這時句子的謂語動詞通常是不及物動詞。如：Gone are the days when we ha nothing to ，其倒裝結(jié)構(gòu)為“so/ neither/ nor+助動詞/系動詞/情態(tài)動詞”，這里的主語同前一個句子的主語指的是同一人或物。例： Never in my life have I seen such a 。有以下幾種形式：(1)副詞置于句首Much as I like it(=Although I like it very much), I will not buy it.(2)動詞置于句首Wait as you may(= Although you may wait), he will not see you.(3).形容詞或名詞置于句首Proud as the nobles are(=Although the nobles are proud), they are afraid to see as he is(=Although he is a child), he can tell right from ：如果名詞前有形容詞修飾時，as引導(dǎo)的倒裝句中要保留不定冠詞。如： Only then did I realize the important of English./ Only when a child grows up does he understand his parents’ 修飾的是句子的其它成分，則無須倒裝Only socialism can save China.(only修飾句子的主語，仍用正常語序) only...but also...引導(dǎo)兩個并列句，前倒后不倒。May you succeed!,要部分倒裝。有時要強調(diào)so 所修飾的形容詞或副詞，常將so連同它所修飾的形容詞或副詞一起提到句首。如： Heruns so fast that he is far ahead of fast does he run that he is far ahead of is so clever that he can work out all the difficult problems in the clever is he that he can work out all the difficult problems in the book.（全部倒裝），或使上下文緊密銜接，句子要部
