24、ll”为直接引语。如果按引用人的观点来引用，则称为间接引语。因此he said that he was very ill为间接引语。said这样的动词称为引话动词，它前面的主语，例如he，可称为第一主语。引语中的主语，如i及he，称为第二主语。引语中的谓语动词称为第二动词。当直接引语转换为间接引语，或间接引语转换为直接引语时，有几个问题需要注意。a大写与标点直接引语放在引号之内，第一个字母要大写，引号前加逗号（间或用冒号），引语末加句号、问号或感叹号，但在间接引语中却不加这些。间接引语必须由that，whether（if）或疑问词（who，why，when等）开头，末尾要加句号。此外，在直接引

25、语中问句可能有倒装语序（助动词放在主语前面），但在间接引语中，问句则需变为自然语序：i say，“he will come”i say that he will comei say：“when will he come？”i ask when he will comeb引话动词与第二动词引话动词可以是say，remark，observe，claim，explain，con- firm；ask，enquire，question；answer，reply；declare，announce；beg，urge，suggest，request，demand；order，command；object，de

26、ny，admit，agree，argue；warn，threaten；think，reflect，consider；write，cable，phone，telex；shout，laugh， sneer等等。若引话动词是现在时或将来时，则当引语由直接变为间接时，第二动词照旧不变。但若引话动词是过去时，则间接引语中的第二动词，就要由现在时变为过去时，由过去时变为过去完成时等。i say（or will say）to him，“john arrives（or will arrive，arrived）on sunday”i say（or will say）to him that john arrive

27、s（or will arrive，arrived）on sundayi said to him，“john arrives（or will arrive，arrived）on sunday i said to him that john arrived（or would arrive，had arrived） on sundayc引话动词与连词1如果间接引语为陈述句，它前面通常都有：say that，know that，tell him that，state that，2如果它是问句，它前面通常有：ask（him）whether（or if），inquire（of him） whether，d

28、emand（of him）whether，wonder whether，want to know whether；或ask（him）w（即疑问词，如who，whom，when，why，which），inquire（of him）w，3如果它是感叹句，它前面通常有：exclaim that，cry out with joy that，4如果间接引语为祈使句，它前面通常有：demand that， ask that，request that，advise that，order that，且里面包含助动词should此外间接引语还可以转换为不定式短语，这时引话动词需要改为宾补动词：1i said，“

29、you are a nice boy”i said that he was a nice boyi thought，“you will fail again”i thought that he would fail again2i said，“are you a nice boy？”i asked whether he was a nice boyi thought to myself，“will he fail again？”i asked myself whether he would fail againi enquired of him，“who knows it？”i enquire

30、d of him who knew it3i said，“what a nice boy you are！”i exclaimed that he was indeed a nice boyi said，“hurrah！we have won the battle”i cried with joy that we had won the battlehe said，“curse it！you are a fool”he exclaimed with an oath that i was a foolhe said，“bravo！you have done something wonder fu

31、l”he applauded me，saying that i had done something wonderful4i said to him，“be a nice boy”i advised that he should be a nice boyi advised him to be a nice boyi said to him，“see me at the station”i requested that he should see me at the stationi requested him to see me at the stationd代词此外还要注意，把直接引语变为

32、间接引语时，代词需作改变。如果在直接引语中代词为第一人称，在变为间接引语时，将变为与第一主语一致的代词。i said，“i can do it”i said that i could do ithe said，“i must go”he said that he must goyou said，“i know”you said that you knewwe said，“we can do it”we said that we could do itthey said，“we must go”they said that they must goi said“we can do it”i sa

33、id that we could do it（we中包括i）如果在直接引语中，代词为第二人称，在间接引语中它将变成与引话动词的宾语一致的人称：i told him，“you are right”i told him that he was righti told you，“you are right”i told you that you were righthe told me，“you are right”he told me that i was righthe told us，“you are right”he told us that we were rightwe told the

34、m，“you are right”we told them that they were right”to somebody也可看作是宾语：he said to me（=told me），“you are right”he said to me that i was righthe explained to them，“you have gone the wrong way”he explained to them that they had gone the wrong way引话动词的宾语有时可以省略，但它在间接引语中可能需要说出来：they asked me when i would g

35、et marriedi said，“you will learn it very soon”i said that they would learn it very soon如果在直接引语中代词为第三人称，在间接引语中，它可以保持不变：i told you，“he is crazy”i told you that he is crazyhe told me，“she is crazy”he told me that she was crazywe told him，“they are crazy”we told him that they were crazyhe told me，“he is

36、 crazy”（这两个he代表两个不同的人）he told me that a certain person was crazy还需指出，上述代词，在直接或间接引语中，可以为任何“格”，而不仅仅是主格：he told me，“i will ask my brother to take me to the pictures”he told me that he would ask his brother to take him to the pictureshe declared “we must urge them to return our territory to us！”he decla

37、red that we must urge them to return our territory to use时间副词（短语）间接引语中的时间副词（短语）可能和直接引语中的时间副词（短语）不同，这是因为原来说话人提到的时间可能与现在引话人提到的时间不同：he said，“mary is very busy now”he said that mary was very busy thenhe said，“mary came yesterday”he said that mary had come the day before（or the previous day）he said，“mary

38、 came five days ago”he said that mary had come five days before（or five days earlier）he said，“mary will come tomorrow”he said that mary would come the following day（or the next day）he said，“mary will come in five days！”he said that mary would come five days afterwards（or later）f第一主语及引话动词的位置在新闻报导中第一主

39、语有时放在引话动词的后面：said stevens，“”comments drlee，“”boasted asia bank president john bush，“”第一主语及引话动词，除了放在直接引语前面外，还可放在其他位置：he said，“oh！ i have done my best”“oh！”he said，“i have done my best”（但不说said he）“oh！i have done my best，”he said（但不说said he）“oh！i have done my best”（如果大家都清楚这话是谁说的，第一主语及引话动词也可不必说出。）在第一主语

40、及引话动词放在其他位置时，要注意标点符号：he said，“oh，i have done my best；i have made every effortbut all in vain”“oh，”he said，“i have done my best；i have made every effortbut all in vain”“oh，i have done my best，”he said；“i have made every effort，but all in vain”如果引话动词有较长的修饰语，最好把它放在主语及引话动词前面，如果主语及引话动词在直接引语后面，长修饰语最好放在引话动

41、词后面：after a short space of silence he said，“ill consider this problem”“ill consider this problem，”he said after a short space of silence如果主语和引话动词放在直接引语的中间或后面，作主语的名词可以放在引话动词的后面或前面（若主语是人称代词，只能放在动词后面）：“i think so，”he said（or leo said，said leo）（很少说said he）“everything is ok！”she says（or amy says，says amy

42、）（很少说 says she）简单句的合并1786 两个或更多简单句可以合并成一个比较复杂的句子，这种练习对学习写作的人很有好处。两个或更多简单句可借助并列连词合并成一个复合句：he saw johnhe greeted himhe saw john and he greeted himi called on marymary was illi called on mary，but mary was illhe has not a single pennyhe has to beghe will be starvedhe has not a single penny，so he has to

43、beg，otherwise he will be starved两个或更多简单句，可以加上从属连词，把一个或更多句子变为名词从句、定语从句或状语从句，这样来合并成为一个复杂句。1变成名词从句：he has arrivedi know iti know that he has arrivedhe may have an accidenti am afraid i am afraid that he may have an accidenthow many were killed？i am not surei am not sure how many were killedhow did he ac
