句式变换
1.非谓语和从句的变换
非谓语动词包括动词不定式、动名词、现在分词、过去分词。使用非谓语动词可以在有限的空间内容纳更多的信息，使句子结构紧凑、逻辑严谨。
【佳句选粹1】
【原文】 【优化】
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”改为“deciding”，if 条件从句改为动名词短语作主语，句子结构变得更加紧凑，简洁明了。

【佳句选粹2】
【原文】 【优化】
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】　把原句中的原因状语从句用分词的形式变换，又用了个定语从句把两个句子连起来，使得句子更紧凑，更严谨。

2.强调句的变换
写作中，常使用强调句来达到突出重点的目的。强调句的基本结构是：it is/was＋被强调部分＋that/who＋句子其他成分。另外，英语中还经常使用助动词do/does/did对谓语动词进行强调。
【佳句选粹1】
【原文】 【优化】
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】　改成强调句后，强调说明是“in the street”而不是别的地方，句意的表达更加有力。

【佳句选粹2】
【原文】 【优化】
we should be careful when we cross the street. do be careful when we cross the street.
【分析】　改成强调句后，语气增强了，句意的表达更加有力，可翻译为“过马路时务必要小心”。

3.倒装句的变换
句子成分在句子中都有一定的位置，但有时可以把某些句子成分前后倒置，以达到突出强调的目的或起到某种修饰作用。
英语中倒装分为全部倒装和部分倒装。部分倒装在写作中比较常用，经常由否定词提前或“only＋状语”提前引起。
【佳句选粹】
【原文】 【优化】
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，引起部分倒装，突出了现在时态，句意表达更有力。
