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。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 didn’t 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 don’t 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 don’t know _____ he will come or not.
I don’t 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whether与to do 不定式连用只能用whether作主语只能用whether1. ( ) —Do you know ____ Jane visits her

Grammar FocusExclamatory statements感叹句顾名思义感叹句就是英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 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.Exclamations 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！
How 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 cakes 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：① What a fine day! 多么晴朗的天呀！
 ② What an honest boy! 多么诚实的孩子呀！
 ③ What red apples! 多么红的苹果呀！
 ④ How cool! 好凉快呀！ 
⑤ How wonderful! 精彩极了！Exclamations 例题讲解◆ 请在横线上填上你认为正确的单词
1.__ great film it is!
2.___ exciting they are!
3._____ a pretty girl she is!
4._____ kind you are!
5._____ bad weather it is!
◇点拨：牢记感叹句的两个基本结构：
What+(a/an)+adj.+n.+subject+v
How+adj./adv.+subject+v.参考答案：
1.Whata
2.How
3.What
4.How
5.WhatExclamations 例题小结★ 判断一个感叹句是由What还是How引导，可以看形容词后出现的名词是不是主语，若不是，则可判定这个感叹句是由What引导的.如果名词是单数，记得在What后加a/an.
★ 同样可以根据句子的结构来判定:
1.What+形容词+名词+主语+动词.
（What 形 名 主 谓）
2.How+形容词+主语+动词.
（How 形 主 谓）填入适当的词完成下列感叹句。
