对偶句是平行结构的一种特殊句型。对偶句是指由两个结构相同或近似并且表意相异和相反的两个平行分句构成的句子，对偶句表意“强劲有力”，能给人留下深刻的印象，能极大地增强话语表达的说服力。对偶句主要用于说明文、议论文及演讲等正式文体中。

7.短句、长句
英语语句的短句与长句各有其文本特点，一般而言，短句表意简单明了，而长句则长于表达复杂而严密的思想，以及形象和印象的描写。因此，短句多用于书信、广告、工作报告等应用文本中；长句则多用于政法文本和理论思辨性的文本中。
长句语例：
（1）Her mouth and chin， they said， were too large and long， and so they might be for a goddess in marble， nut not for a woman whose eyes were fire， whose look was love， whose voice was the sweetest low song， whose shape was perfect symmetry， health， decision， activity， whose foot as it planted itsels on the ground was firm but flexible， and whose motion， whether rapid or slow， was always perfect grace-agile as a nymph， lofty as a queen-now melting， now imperious， now sarcastic-there was no single movement of hers but was beautiful.（描写)
（2）I've directed Secretary Powell to work with fellow members of the Council to endorse the timetable the Iraqis have adopted， to express international support for Iraq's interim government， to reaffirm the world's security commitment to the Iraqi people， and to encourage other U.N.members to join in the effort.（表达复杂思想）
8.平衡句、失衡句
语句的前后结构，特别是主语结构和表语或宾语结构间的长度趋于大致平衡的语句称为平衡句；相反，主语结构和表语或宾语结构间，其中之一过长而另一个又过短的语句称为失衡句。人们在平常的写作中多使用平衡句。可是，有时候，偶尔使用一些失衡句也会给人耳目一新的感觉，产生另一些不一样的文本效果。
语例：
（1）Completing the five steps to Iraqi elected self-government will not be easy.
（2）Helping construct a stable democracy after decades of dictatorship is a massive undertaking.
（3）Whether this new medicine will be widely applied clinically or not is still a question.
上述主要介绍了8种英语句型分类。写作学习者应通过熟练掌握和运用这些不同的英语语句类型，来达到写作中语句的多样化。当然，在实际的写作中，句型的多样化应考虑文本特征而恰当地运用多种多样的句型，切不可为了语句的多样化而硬性地把各种句型搬到一篇文本里面。写作中，最终是内容决定形式。写作者应首先考虑的是文本的内容，其次才是形式，语句多样化更多地体现于文本的形式上。当然，如果各种语句的使用，既适合了文本语义的表达，又兼顾了语句的多样化，那就再好不过了。然而，最上乘的方法却是无法之法，当一个写作者已对英语语句掌握得炉火纯青，写作中在表达文本思想时，并未特意去考虑句型句式，而自然地就采用了各种相应的最佳句型句式。
（二）英语语句句式结构的转换
英语语句句式这里主要是指英语语句的微观的内部结构。弄清楚英语语句的微观的内部结构，对每一个英语写作者来说都是十分重要的。然而，要具备扎实的英语写作能力，在英语语句的掌握和运用方面，仅仅具备单个或一个独立语句的语法分析能力是远远不够的，英语写作者还应该对英语语句的基本句式，以及各句式内部结构间的转换规律有一个总揽性的了解，然后才能真正拓展写作中的语句运用能力，使英语语句运用达到灵活自如，随心所欲。
在英语语句的运用上，就单个英语语句而言，一个英语语句的运用尽可以是多种多样的。例如，为了表达一个师范生第一次走上讲台讲课心里感到很紧张这个意思，我们尽可以采用以下不同的英语表达句式。
语例：
（1）The teachers' college student was giving his class the first time and he felt very nervous.
（2）The teachers' college student was giving his class the first time； he felt very nervous.
（3）The teachers' college student giving his class the first time felt very nervous.
（4）The teachers' college student felt very nervous during his first class giving.
（5）The teachers' college student's first class giving made him feel very nervous.
