1、Unit 2 I think that mooncakes are delicious!,Grammar,一、宾语从句的概念,I like my teacher.（名词作宾语) I know him .（代词作宾语） I know Mr Li teaches English. (句子作宾语）,宾语从句即句子作宾语，而不再是一个词或短语作宾语。,宾语从句： 概念：在复合句中，由一个句子充当宾语,这个句子叫做宾语从句。 宾语从句由“关联词+主语+谓语”构成。 引导宾语从句的关联词有that, if, whether, what, who, where, why和how等。 宾语从句要用陈述句语序。
2、,Grammar,总结一下吧！宾语从句的三要素：,一、关联词：that, if, whether, what, who, where, why和how等。 二、时态：1.当主句为一般现在时时态时，从句根据需 要来确定时态。 2.当主句用一般过去时时态时，宾语从句要用过去的某种时态。注意：当从句是客观真理的时候，无论主句什么时态，从句一律用一般现在时。 三、语序：宾语从句用陈述句语序，即 “主语+谓语”。如： e.g. He asked me where my school was. I didnt know who she was.,由从属连词that引导的宾语从句,注：that 在句中无词汇
3、意义，在从句中不能充当成分， 在口语当中往往省略,e.g. I hear (that) _. （一小时后他会回来） He said (that) _. （他非常想念我们） The teacher told us (that) _. （地球围着太阳转）,he will be back in an hour,he missed us very much,the earth moves around the sun,注意：当从句是客观真理的时候，无论主句什么时态，从句一律用一般现在时,由从属连词whether, if 引导的宾语从句,e.g. 1. Ask him _. （他是否能来） 2. I d
4、ont know _.（是否要下雨）,whether (if) he can come,whether it is going to rain or not,当句末为or not时，引导词只能用whether而不能用if.,If 与whether 的区别,I dont know _ he will come or not. I dont care of _ he is handsome. He wondered _ to stay here the next week. _ he will come is not decided.,与or not 连用只能用whether,介词后只能用whet

8、语中带有感叹号的句子，表示说话人惊奇、愤怒、赞美、喜悦等情绪。 近年来，感叹句的构成及转换是中考常考的考点之一。 感叹句一般是由“what” 和“how”来开头的句子，“what”修饰名词，“how”修饰形容词和副词。,结构： 1.What+a/an+形容词+可数名词单数+主语+谓语动词！ 2.What+形容词+可数名词复数+主语+谓语动词！ 3.What 形容词不可数名词主语谓语！,Exclamations 感叹句, What an interesting story it is! What 形容词 名词 主语 谓语 多么有趣的故事啊！ What beautiful flowers they
9、 are! What 形容词 名词 主语 谓语 多么漂亮的花啊！ What delicious milk it is ! 多么美味的牛奶呀！,由“what”引导的感叹句：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。由 what 引导的感叹句，其句子结构可分为以下三种： 1.“ What + a/an 形容词可数名词单数主语谓语！”。如： What a nice present it is! 它是一件多么好的礼物啊！ What an interesting book it is! 它是一本多么有趣的书啊！ 2. “ What 形容词可数名词
10、复数主语谓语！”。如： What beautiful flowers they are! 多么漂亮的花啊！ What good children they are! 他们是多么好的孩子啊！ 3：“ What 形容词不可数名词主语谓语！”。如： What fine weather it is today! 今天天气多好啊！ What important news it is! 多重要的新闻啊！,实战 _bad weather it is! A.How B.How a C. What D.What a,正确答案：C 解析：形容词后出现了非主语的名词，故这个感叹句应该由What来引导.,Exclam
11、ations 感叹句,例： How lucky we are! How 形容词 主语 动词 我们多幸运啊！ How quickly the time passed! How 副词 主语 动词 时间过得真快啊！,结构： How+形容词/副词+主语+谓语动词.,由“how”引导的感叹句：“how”意为“多么”，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，句子的结构是： How+adj.（adv.）+主语+谓语. 1. How 形容词 / 副词主语谓语！”。如： How careful she is! 她多么细心啊！ Ho
12、w fast he runs! 他跑得多快啊！ 2. “ How 形容词 a/an 可数名词单数主语谓语！”。 How beautiful a girl she is! 她是个多么漂亮的姑娘啊！ 3. “ How 主语谓语！”。 How time flies! 光阴似箭！ 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。 How beautiful a girl she is! What a beautiful girl she is! What delicious cakes these are! How delicious these ca
13、kes are!,实战 _interesting it is to go sailing in Qingdao in summer! A.What B.What an C.How D.How an,正确答案：C 解析：看出这个感叹句的结构是“形 主 动”，所以是How引导的.,Exclamations 结构比较解析, How lucky we are! How 形容词 主语 动词 What an interesting story it is! What 形容词 名词 主语 动词 点拨：如果在一个感叹句中，形容词后出现了名词且不是主语，那么这个感叹句就是以What引导的.,感叹句在表示激动强烈
