1、小學(xué)英語語法陳述句陳述句：陳述句主要是用來陳述事實(shí)或觀點(diǎn),傳遞信息,提供情 況.陳述句又分為肯定的陳述句和否認(rèn)的陳述句,簡稱為肯定句(TheAffirmative Sentence) 和否認(rèn)句(The Negative Sentence) 兩 種.陳述句在書寫時句末有句號,而在朗讀時那么用降調(diào).例句：China is the largest country in Asia.中國是亞洲最大的國家.I didn't tell him anything.我什么也沒有告訴他.陳述句轉(zhuǎn)換感慨句詳解一、如何快速掌握感慨句 學(xué)會分析五種根本句型的句子成分是快速掌握感慨句的關(guān)鍵,陳述句變感慨句實(shí)際上就

2、是句子成分位置的移動.例 1 She is smiling sweetly.tHow sweetly she is smiling!(移動狀語)二、 哪些句子成分可能會移動位置通過對句子成分的分析我們就可以確定哪個句子成分需要挪動 位置,一般說來含有形容詞的名詞短語、形容詞短語和副詞短語 需要變動位置.位置可能會變動的句子成分：賓語、表語和狀語.例 2 Mr Turner told us a funny story.t What a funny story Mr Turner told us!移動賓語含有形容詞的名詞短語三、如何確定使用what還是使用how?當(dāng)我們做句型變換或選擇題時需要自己

3、確定到底是用what還是用how, 一般可以這樣來確定：位于主語之前的是名詞短語時用 what,是形容詞或副詞短語時用how.但這種格式例外：how+ adj.+ a/ an + N例 3 What a cool bike you are riding!a cool bike名詞短語例 4 How fast he is riding!fast副詞例 5 How cool a bike you are riding!how + adj. + a/ an +N四、如何判斷是否使用冠詞、使用什么樣的冠詞 名詞的復(fù)數(shù)形式和不可數(shù)名詞之前不使用冠詞,以元音音素開頭的詞語之前用an,以輔音音素開頭的詞語之

4、前用a.例 6 What beautiful sunshine it is today!(sunshine不可數(shù)名詞例 7 What a useful book this is!(useful以輔音音素開頭例 8 What an old house that is!(old以元音音素開頭五、感慨句有哪幾種格式簡單地說是“兩型七式:兩種句型是以what開頭的句型和以how開頭的句型,七種格式是 what + a + adj. + N+ S +V what + an + adj. +N +S +V what + adj. + N( 不可數(shù))+ S +Vwhat + adj. + N可數(shù)名詞復(fù)數(shù)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(可數(shù)名詞復(fù)數(shù)形式+ S + V結(jié)構(gòu)例 9 What good teachers they are!(what + adj. + N(可數(shù)名詞復(fù)數(shù)形式+ S+V結(jié)構(gòu)例 10 How warmly they are discussing!(how + adv. + S + V 結(jié)構(gòu))例 11 How beautiful a picture it is!(how + adj

6、. + a/ an +N + S + V 結(jié)構(gòu))六、以what開頭的句型和以how開頭的句型怎樣進(jìn)行轉(zhuǎn)換 這兩種句型之間的轉(zhuǎn)換主要是指以下兩種情況而言的：1. 含有“ a/ an + adj. + N 結(jié)構(gòu)的句子方法是把形容詞單獨(dú)抽出來放在名詞短語的前面和how搭配使用.2. 名詞短語作主語而表語是形容詞的句子方法是把主語當(dāng)作“a/an + adj. + N 結(jié)構(gòu)的中央名詞而用人稱代詞充當(dāng)主語.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!(說明：N代表名詞,未特別說明者代表可數(shù)名詞的單數(shù)形式,S代表主語,V代表動詞)七、 在感慨句中哪些詞語常常省略常常省略的是充當(dāng)主語的人稱代詞和動詞be.例 14 What a naughty boy! 省略了 he is八、有什么巧妙的方法記住這些規(guī)律嗎以上的解釋說明似乎很復(fù)雜,其實(shí)理清了思路、抓住了要領(lǐng)、掌 握了規(guī)律并不是那么難的.為了便于同學(xué)們記憶我把以上規(guī)律編 成了一段順口溜,請同學(xué)們對照閱讀.陳述句述事實(shí),感慨句表感情.陳述變成感慨句,主謂系表先分清.賓語狀語移句首,表語亦須打頭陣.名詞之前用what,形副之前ho

8、w先行.復(fù)數(shù)名詞無冠詞,事先分析莫輕心.如果名詞不可數(shù),摒棄a, an不留情.冠詞a, an要清楚,清音輔音是標(biāo)準(zhǔn).句子結(jié)構(gòu)要完整,標(biāo)點(diǎn)符號亦變更.總結(jié)規(guī)律進(jìn)步快,編個歌訣給你聽.肯定句變否認(rèn)句的方法1. be動詞的否認(rèn)式be動詞根據(jù)不同的人稱和時態(tài)有不同的形式,在一般現(xiàn)在時中 是am , is , are可用作聯(lián)系動詞,構(gòu)成否認(rèn)式時,一律在其后面加否認(rèn)詞not.He is reading. - He is not reading. They are from China. -They are not from China.2. 情態(tài)動詞的否認(rèn)式情態(tài)動詞的否認(rèn)式是在其后面直接加not.如：I

9、can swim. - I can ' t swim. He can dance. - He can ' t dance. You should go to school at seven. - You shouldn ' t go to school at seven.3. 實(shí)義動詞的否認(rèn)句實(shí)義動詞變否認(rèn)句時,要借助助動詞 do , does ,在一般現(xiàn)在時 中用do或者does其句子結(jié)構(gòu)為：主語 + don' t / doesn' t +動 詞原形+其它例如：I like pop music. - I don ' t like pop mus

11、通常改為tell sb .如：“It ' s a secret. he said to me.他對我說.如：“這是秘密.t He told me that it was a secret.他對我說那是秘密.2假設(shè)直接引語是兩個并列的陳述句,要注意在第二個賓語從句前加連詞 that.如： He says, “ I like singing and I want to be a singer. 他說.如：“我喜歡唱歌,我想當(dāng)歌手. Hesays that he likes singing and that he wanted to be a singer.他說他喜歡唱歌,想當(dāng)歌手.在此種情
