1、I think that mooncakes are deliciousSection AGrammar Focus-4c重点：1.What 和how 引导的感叹句2.that,if and whether引导的宾语从句感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用what和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。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+(it is).如

2、：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 children they are!他们是多么好的孩子呀！What beautiful flowers they are!多么漂亮的花呀！What delicious food it is!多么有味的食物呀！What heavy snow it is!多么大的雪呀由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

3、为动词，这类句子的结构形式是：How+adj.（adv.）+主语+谓语+(it is).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！How well she sings!她唱得多好呀！How hard they are working now!他们干得多么起劲呀！在表示同一意义时，英语感叹既可用what引导，也可用how引导。如：What a hot day it is!How hot the day is!多么热的天气呀！What tall bui

4、ldings they are!How tall the buildings are!多么高的楼房呀！What bad weather it is!How bad the weather is!多么糟糕的天气呀！What bright sunshine it is!How bright the sunshine is!多么明亮的阳光呀！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！What an honest boy!多么诚实的孩子呀！What red apples!多么红的苹果呀！How cool!

5、好凉快呀！How wonderful!精彩极了！How后面直接加形容词,What后面先加名词2.Object clauses withthat,if and whether一、宾语从句的概念在句子中起宾语作用的从句叫做宾语从句。We know Mr Green teaches English.She asked if these answers were right.二、宾语从句三要素引导词（连接词）语 序时 态1.I hear(that)_.2.He said(that)_.3.The teacher told us(that)_ _.he will be back in an hourhe

6、 missed us very muchthe earth moves一、由that引导的宾语从句注：that 在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。around the sunObject clauses with that二、连词that不能省略的几种情况1.从句的主语是that。如：He says that that(主语）is a real kings hat.他说那是一个真的王冠。2.that从句中含有主从复合句。如：Im afraid that if youve lost it,you must pay for it.3.主、从句之间有插入语时。如：It say

7、s here,on this card,that it was used in plays.卡片上写着，它是古代演戏用的。4.若出现两个或两上以上的由that引导的宾语从句，且由并列连词连接时，只有第一个连词that可以省略。如：She said(that)she would come and that she would also bring her son.她说她要来，还要带她的儿子来。.if和whether引导宾语从句时，作“是否”讲，一般情况下，二者没有区别，可以换用。但if常用于口语中，whether比较正式。如：Millie asked if/whether he liked th

8、is sweater.米莉问他是否喜欢这件羊毛衫。The fisherman wants to know if/whether it will rain.渔民想知道天是否会下雨。Object clauses with if and whether由if/whether引导的宾语从句.if和whether引导宾语从句时，要注意宾语从句三要素，即连词、语序和时态。由于if和whether连接的是一般疑问句，因此要注意把从句语序改为陈述句语序。如：Does Mr Zhao live in Room 208?Could you tell me?Could you tell me if/whether

9、Mr Zhao lives in Room 208?其次要注意时态变化：1.若主句是一般现在时，从句用任何所需时态。如：He wants to know if/whether they had a good journey home.他想知道他们回家旅途是否愉快。2.若主句是一般过去时，从句则用跟过去相关的时态。一般现在时一般过去时一般过去时过去完成时现在进行时过去进行时一般将来时过去将来时现在完成时过去完成时如：Did the train leave?She didnt know.She didnt know if/whether the train had left.if和whether的

10、区别二者在下列几种情况下不能换用：1.宾语从句置于句首表示强调时，应用whether，不用if。如：Whether this is true or not,I cant say.这是否对，我不能说。2.宾语从句与or not直接连用时，应用whether，不能用if。如：I dont know whether or not he will come tomorrow.我不知道他明天是否来。3.与动词不定式连用时，只能用whether。如：She cant decide whether to go to America.她不能决定是否去美国。4.从句作介词宾语时，只能用whether。如：I w

11、orry about whether I hurt her feeling.我担心是否伤了她的感情。5.宾语从句的谓语动词是否定形式时，只能用if，不能用whether。如：Tom wants to know if he wont come here tomorrow.汤姆想知道他明天是否不来这儿。6.if意为“假如，如果”时，可以引导条件状语从句，而whether没有这个用法。如：If Simon comes here tomorrow,Ill call you.假如西蒙明天来这儿，我将打电话告诉你。改为含宾语从句的复合句1.Will the train arrive on time?I w
