在一篇短文中，如果句子結(jié)構(gòu)要么是“主謂賓”，要么是“主系表”，則顯得很單調(diào)，讀起來乏味。若對簡單句進行一下轉(zhuǎn)換，使其主語靈活，句子結(jié)構(gòu)活潑，則給人的感覺就大不一樣。 簡單句之間的轉(zhuǎn)換有下面三種方法： 一、轉(zhuǎn)換句子結(jié)構(gòu) [例]　李東住在南方。他的家鄉(xiāng)經(jīng)常下雨。 一般： Li Dong lives in the south.It often rains in his hometown. 較好： Li Dong is from the south.There is a lot of rain in his hometown. [分析]　“一般表達”中的兩個句子均是“主謂”結(jié)構(gòu)，比較單調(diào)。把它們分別轉(zhuǎn)換為“主系表”結(jié)構(gòu)和there be句型后，句子就顯得比較活潑。 [例]　你每天幫我學(xué)英語。你太好了！ 一般： You help me study English every day. You are very kind.

　　較好： It's very kind of you to help me learn English every day.

　　較好： How kind of you to help me learn English every day!

　　[分析]　“一般表達”句子之間的關(guān)系松散，轉(zhuǎn)換為it作形式主語或感嘆句后句子讀起來很流暢。 二、轉(zhuǎn)換句型

　　寫作中常用于轉(zhuǎn)換的三個重點句型： 1．there be句型 there be句型也是簡單句中的一種常用句型，在作文中經(jīng)常使用。在there be句型中，有時there be還可以換用there seems/seemed to be(似乎有)，there happened to be(碰巧有)，there may/might be(也許有)，there must be(肯定有)，there can't be(不可能有)，there ought to/should be(應(yīng)該有)等。 我家有五口人。 There are five people in my family. 操場上碰巧有很多人。 There happened to be a lot of people on the playground. 2．感嘆句 感嘆句是作文中很有用的一種句型，常見的感嘆句有兩種： [句型1]　What＋(冠詞)＋形容詞＋名詞＋主謂結(jié)構(gòu)＋感嘆號 [句型2]　How＋形容詞或副詞＋主謂結(jié)構(gòu)＋感嘆號 What an interesting film (it is)! ＝How interesting a film (it is)! 3．強調(diào)句型 強調(diào)句型也是作文中常用的一種句型，強調(diào)句型的結(jié)構(gòu)是： It is/was＋被強調(diào)部分＋that/who＋原句其他部分。 I met my friend in the street yesterday.

　　→It was I who/that met my friend in the street yesterday. (強調(diào)主語)

　　→It was my friend that I met in the street yesterday. (強調(diào)賓語)

　　→It was in the street that I met my friend yesterday. (強調(diào)地點狀語) →It was yesterday that I met my friend in the street. (強調(diào)時間狀語)

　　注意：強調(diào)時間和地點時，不能用when或where，要用that。 三、轉(zhuǎn)換詞語

　　[例]　杰克是我們學(xué)校的學(xué)生。他學(xué)習(xí)特別努力。 一般： Jack studies in our school. He studies very hard. 較好： Jack studies in our school. He works hard at his lessons. [分析]　“一般表達”中的謂語重復(fù)使用study，顯得呆板。詞語轉(zhuǎn)換后，句子就“活”起來了，讀起來有滋有味。 [例]　媽媽匆匆忙忙去上班，連早餐都沒吃。 一般：Mother went to work in a hurry. She didn't have breakfast.

　　較好：Mother went to work in a hurry without having breakfast.

　　[分析]　“一般表達”中的兩個簡單句之間關(guān)系松散，使用介詞短語進行轉(zhuǎn)換后使句子內(nèi)部結(jié)構(gòu)緊湊，讀起來一氣呵成。 * *
