现在就从三方面来看看句子合成法的问题。
1. 由两三个简单句合成一个长的简单句。例如：
（1） John ran away. He escaped the danger.
→ Running away, John escaped the danger.
（2） The hunter took up his gun. He shot the boar.
→ The hunter took up his gun to shoot the boar.
（3） The king died. The queen heard about it. She fainted.
→ On hearing about the king's death, the queen fainted.
（4） Kelvin is my good friend. He is a strong supporter of social justice.
→ Kelvin, a strong supporter of social justice, is my good friend.
（5） The rascal kicked the cat. He kicked it on the back. He kicked it intentionally.
→ The rascal kicked the cat on the back intentionally.
2. 由两三个简单句合成一个并列句。例如：
（6） John was sad. He kept quiet.
→ John was sad but he kept quiet.
（7） Take the book. Leave it there.
→ Take the book or leave it there.
（8） Sean did not come to class today. He had a bad headache.
→ Sean did not come to class today, for he had a bad headache.
（9） Bruce was lying on the bed. He looked at the ceiling. He saw a lizard.
→ Lying on the bed, Bruce looked at the ceiling and saw a lizard.
3. 由两三个简单句合成一个复杂句。例如：
（10） Kelvin is getting rich. We know about it.
→ We know that kelvin is getting rich.
（11） I like this book. It contains many amusing stories.
→ I like this book which contains many amusing stories.
（12） Helen is sure to get her pay. It is due to her. Why does she complain?
→ Why does Helen complain since she is sure to get the pay due to her ?
（13） The woman was exhausted. She had not slept well the previous night.
→ The woman was exhausted because she had not slept well the previous night.
上面例子显示，简单句由“主语+谓语”（Subject + Predicate） 构成，有时还附有修饰性的短语。并列句由至少两个地位平等的并列分句透过并列连词 （Coordinating Conjunction）如“and, or, but, so, for”等连成。复杂句包括一个主句 （Main Clause）及至少一个从句 （Subordinate Clause）， 通过从属连词（Subordinating Conjunction） 如“That, since, because, when, if”等合成。从属分句因功能不同而分成“名词从句”（Noun Clause）, “副词从句”（Adverb Clause） 和“形容词从句”（Adjective Clause）。
上述诸句式中，复杂句最为多采多姿，不妨多用。为了避免句子太长，难以控制，一个复杂句最好不要超过三个从句。
