1、9BUnit4 Grammar-简单句和复合句之间的转换（二）英语中按句子的结构可分三种：简单句 (simple sentence)；并列句 (compound sentence)和复合句 (complex sentence)。简单句：只有一个主语（或并列主语）和一个谓语（或并列谓语）。e.g. He often reads English in the morning. Tom and Mike are American boys. She likes drawing and often draws pictures for the wall newspapers.并列句：由并列连词（and

2、, but, or等）或分号（;）把两个或两个以上的简单句连在一起构成。e.g. You help him and he helps you. The future is bright; the road is tortuous. 前途是光明的，道路是曲折的。复合句：主句+从句（含有一个或一个以上从句）。主句是一个完整的句子(independent sentence),它可以独立存在。从句是一个不完整的句子,它必须和一个主句连用，不能独立存在。复合句包含：名词性从句（主语从句、宾语从句、表语从句和同位语从句）、定语从句和状语从句等。下面我们看看简单句和复合句之间的转换。1、状语从句可用“介词短
