小学英语语法陈述句

1、小学英语语法陈述句陈述句：陈述句主要是用来陈述事实或观点,传递信息,提供情 况.陈述句又分为肯定的陈述句和否认的陈述句,简称为肯定句(TheAffirmative Sentence) 和否认句(The Negative Sentence) 两 种.陈述句在书写时句末有句号,而在朗读时那么用降调.例句：China is the largest country in Asia.中国是亚洲最大的国家.I didn't tell him anything.我什么也没有告诉他.陈述句转换感慨句详解一、如何快速掌握感慨句 学会分析五种根本句型的句子成分是快速掌握感慨句的关键,陈述句变感慨句实际上就

2、是句子成分位置的移动.例 1 She is smiling sweetly.tHow sweetly she is smiling!(移动状语)二、 哪些句子成分可能会移动位置通过对句子成分的分析我们就可以确定哪个句子成分需要挪动 位置,一般说来含有形容词的名词短语、形容词短语和副词短语 需要变动位置.位置可能会变动的句子成分：宾语、表语和状语.例 2 Mr Turner told us a funny story.t What a funny story Mr Turner told us!移动宾语含有形容词的名词短语三、如何确定使用what还是使用how?当我们做句型变换或选择题时需要自己

3、确定到底是用what还是用how, 一般可以这样来确定：位于主语之前的是名词短语时用 what,是形容词或副词短语时用how.但这种格式例外：how+ adj.+ a/ an + N例 3 What a cool bike you are riding!a cool bike名词短语例 4 How fast he is riding!fast副词例 5 How cool a bike you are riding!how + adj. + a/ an +N四、如何判断是否使用冠词、使用什么样的冠词 名词的复数形式和不可数名词之前不使用冠词,以元音音素开头的词语之前用an,以辅音音素开头的词语之

4、前用a.例 6 What beautiful sunshine it is today!(sunshine不可数名词例 7 What a useful book this is!(useful以辅音音素开头例 8 What an old house that is!(old以元音音素开头五、感慨句有哪几种格式简单地说是“两型七式:两种句型是以what开头的句型和以how开头的句型,七种格式是 what + a + adj. + N+ S +V what + an + adj. +N +S +V what + adj. + N( 不可数)+ S +Vwhat + adj. + N可数名词复数形式

5、)+ S+V how + adj.+ S +V how + adv. + S + V how + adj. + a/ an + N + S+V例 What exciting news it is!(what + adj. + N(可数名词复数形式+ S + V结构例 9 What good teachers they are!(what + adj. + N(可数名词复数形式+ S+V结构例 10 How warmly they are discussing!(how + adv. + S + V 结构)例 11 How beautiful a picture it is!(how + adj

6、. + a/ an +N + S + V 结构)六、以what开头的句型和以how开头的句型怎样进行转换 这两种句型之间的转换主要是指以下两种情况而言的：1. 含有“ a/ an + adj. + N 结构的句子方法是把形容词单独抽出来放在名词短语的前面和how搭配使用.2. 名词短语作主语而表语是形容词的句子方法是把主语当作“a/an + adj. + N 结构的中央名词而用人称代词充当主语.例 12 What an expensive glass he broke! t How expensive a glass he broke!例 13 How beautiful the birds

7、are!t what beautiful birdsthey are!(说明：N代表名词,未特别说明者代表可数名词的单数形式,S代表主语,V代表动词)七、 在感慨句中哪些词语常常省略常常省略的是充当主语的人称代词和动词be.例 14 What a naughty boy! 省略了 he is八、有什么巧妙的方法记住这些规律吗以上的解释说明似乎很复杂,其实理清了思路、抓住了要领、掌 握了规律并不是那么难的.为了便于同学们记忆我把以上规律编 成了一段顺口溜,请同学们对照阅读.陈述句述事实,感慨句表感情.陈述变成感慨句,主谓系表先分清.宾语状语移句首,表语亦须打头阵.名词之前用what,形副之前ho

8、w先行.复数名词无冠词,事先分析莫轻心.如果名词不可数,摒弃a, an不留情.冠词a, an要清楚,清音辅音是标准.句子结构要完整,标点符号亦变更.总结规律进步快,编个歌诀给你听.肯定句变否认句的方法1. be动词的否认式be动词根据不同的人称和时态有不同的形式,在一般现在时中 是am , is , are可用作联系动词,构成否认式时,一律在其后面加否认词not.He is reading. - He is not reading. They are from China. -They are not from China.2. 情态动词的否认式情态动词的否认式是在其后面直接加not.如：I

10、ic. He likes running. - He doesn ' t like running.She does her homework at home. - She doesn ' t do her homework at home陈述句由直接引语变间接引语将直接引语变为由that引导的宾语从句跟在引述动词之后that 也可省略.如:“ I don ' t love her. he says. 他 说.如：“我不爱她. t He says that he doesn' t love her. 他说他不爱她.注息：假设引述动词用的是say to sb,那么

11、通常改为tell sb .如：“It ' s a secret. he said to me.他对我说.如：“这是秘密.t He told me that it was a secret.他对我说那是秘密.2假设直接引语是两个并列的陈述句,要注意在第二个宾语从句前加连词 that.如： He says, “ I like singing and I want to be a singer. 他说.如：“我喜欢唱歌,我想当歌手. Hesays that he likes singing and that he wanted to be a singer.他说他喜欢唱歌,想当歌手.在此种情
