14、I know the man.而这时也可以用一个句子来充当宾语，如： I know that the man is a policeman. 主句 引导词 从句宾语从句三大块: 1. 引导宾语从句的连词； 2. 宾语从句的语序； 3. 宾语从句的时态。.宾语从句的引导词一.陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：I was a good boy.

17、l me?Can you tell me what she is doing?2.Where does she live? Do you know?Do you know where she lives?三) 疑问词引导的宾语从句疑问代词：what、whom、 who、whose、which疑问副词：when、where、why、how例句：1、The book will show you what you must do .用以下开头与下列句子连成宾语从句:1.Do you know 2.I want to know 3. Can you tell me 1. What is this ?2

18、. What are you doing ?3. Where do you live ?4. When does he get up ?5. How did you go to work?6. Who will you play with?.宾语从句的语序必须是陈述语序句式连词语序例句陈述句That不变I think that we can be good friends.一般疑问句if/whether改为陈述语序I cant remember if I posted the letter.特殊疑问句特殊疑问词改为陈述语序He asked who was our English teacher

19、.宾语从句与主句的时态要相互呼应1. 如果主句的时态是一般现在时，宾语从句的时态根据具体情况来确定，可以是_时态。I dont think (that) you are right.Please tell us where well go fishing tomorrow.Do you know when Mr. Smith moved here?2. 如果主句的时态是一般过去时，宾语从句只能用相应的_时态（一般过去时， 过去进行时， 过去将来时，过去完成时）。例如：He told me that he was born in Beijing in 1992.He said that he w

20、ould go back to the U.S. soon. 特殊情况：1.从句说明的是一般真理、客观事实、自然现象、名言时，任用现在时。 Dad told us that it is better to do than to say. He told the boy that three and three is six. Could you tell me where the bookshop is.但在有些情况下，只能用whether，不能用if：1. whether引导的从句常可以与连词or或or not直接连用，而if一般不能。如： 正： Let me know whether yo

21、u can come or not. 误： Let me know if you can come or not. 2. 当宾语从句提到句首时，只能用whether引导，而不能用if。如： 正： Whether it is true or not, I cant tell. 误： If it is true or not, I cant tell. 3. whether可以引导带to的不定式，if则不能。如： 正： I dont know whether to accept or refuse. 误： I dont know if to accept or refuse. 4. whether

22、及其引导的成分可放于介词之后，作介词的宾语，但if不能。如： 正： I worry about whether I hurt her feelings. 误： I worry about if I hurt her feelings. 5. whether可以引导从句，作主语、表语或同位语，而if不能。如： 正： It was uncertain whether he would come. 误： It was uncertain if he would come. 6.若用if会引起歧义时，则用whether。Please let me know if you like the book可理

23、解为：aPlease let me know whether you like the book.bIf you like the book，please let me know.1 Miss Green didnt tell us _ in 2009. A. where does she live B.

25、e from感叹句感叹句是表达喜、怒、哀、乐以及惊奇、惊讶等强烈感情的句子。感叹句通常由 what 或 how 引导。what和how与所修饰的词置于句首，其它部分用陈述句语序。 一、 由what引导的感叹句：what意为多么用作定语，修饰名词（被强调部分），单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是： what+(a/an)+adj.+n.+主语+谓语.如： What a clever girl she is! 多么聪明的姑娘呀！ What an interesting story it is! 多么有趣的故事呀！ What good chi

26、ldren they are! 他们是多么好的孩子呀！ What delicious food it is! 多么有味的食物呀！ 二、由how引导的感叹句：how意为多么，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是： How+adj.（adv.）+主语+谓语. 如： How cold it is today! 今天多么冷呀！ How nice the pictures are! 多么漂亮的图画呀！ How happy they look! 他们显得多么高兴呀！ 可用句型：“ How 形

27、容词 a/an 可数名词单数主语谓语！”。如：How beautiful a girl she is! 她是个多么漂亮的姑娘啊！可用句型：“ How 主语谓语！”。如：How time flies! 光阴似箭！三、由 what 引导的感叹句与由 how 引导的感叹句有时可以转换，但句中部分单词的顺序要有所变化。如：How beautiful a girl she is! What a beautiful girl she is!What delicious cakes these are! How delicious these cakes are!四、 感叹句在表示激动强烈的感情时，口语中常常采用省略句，其后面的主语和谓语往往略去不讲。 如： What a fine day! 多么晴朗的天呀！ How wonderful! 精彩极了！
