句式變換
1.非謂語和從句的變換
非謂語動詞包括動詞不定式、動名詞、現(xiàn)在分詞、過去分詞。使用非謂語動詞可以在有限的空間內(nèi)容納更多的信息，使句子結(jié)構(gòu)緊湊、邏輯嚴謹。
【佳句選粹1】
【原文】 【優(yōu)化】
it must be realized that people should be cautious when they decide which books they should choose to read since if they read bad books，it will be time¬wasting and harmful. it must be realized that people should be cautious deciding which books they should choose to read since reading bad books is time¬wasting and harmful.
【分析】 把“when they decide”改為“deciding”，if 條件從句改為動名詞短語作主語，句子結(jié)構(gòu)變得更加緊湊，簡潔明了。
【佳句選粹2】
【原文】 【優(yōu)化】
because i was ill，i didn’t go to the party . the party was organized by my classmates yesterday. being ill，i didn’t go to the party which was organized by my classmates yesterday.
【分析】 把原句中的原因狀語從句用分詞的形式變換，又用了個定語從句把兩個句子連起來，使得句子更緊湊，更嚴謹。
2.強調(diào)句的變換
寫作中，常使用強調(diào)句來達到突出重點的目的。強調(diào)句的基本結(jié)構(gòu)是：it is/was＋被強調(diào)部分＋that/who＋句子其他成分。另外，英語中還經(jīng)常使用助動詞do/does/did對謂語動詞進行強調(diào)。
【佳句選粹1】
【原文】 【優(yōu)化】
i met a friend of mine in the street yesterday. it was in the street that i met a friend of mine yesterday.
【分析】 改成強調(diào)句后，強調(diào)說明是“in the street”而不是別的地方，句意的表達更加有力。
【佳句選粹2】
【原文】 【優(yōu)化】
we should be careful when we cross the street. do be careful when we cross the street.
【分析】 改成強調(diào)句后，語氣增強了，句意的表達更加有力，可翻譯為“過馬路時務(wù)必要小心”。
3.倒裝句的變換
句子成分在句子中都有一定的位置，但有時可以把某些句子成分前后倒置，以達到突出強調(diào)的目的或起到某種修飾作用。
英語中倒裝分為全部倒裝和部分倒裝。部分倒裝在寫作中比較常用，經(jīng)常由否定詞提前或“only＋狀語”提前引起。
【佳句選粹】
【原文】 【優(yōu)化】
everyone knows that we are busy all day . we know seldom what is happening both at home and abroad，let alone what we can do for our country. everyone knows that we are busy all day.seldom do we know what is happening both at home and abroad，let alone what we can do for our country.
【分析】 “seldom”位于句首，引起部分倒裝，突出了現(xiàn)在時態(tài)，句意表達更有力。
