4、读长难句的化解阅读理解难点在长难句上,所谓长难句就是众多语法结构按照一定的语法顺序堆砌起来,使同学们看见就晕眩。一个英语句子之所以难以理解有许多原因,其中一个主要原因是句子太长或者句子结构复杂。句子过长或者复杂无非是该句除了主干之外还包含了一些附加部分,如插入语、同位语、分隔现象、各种从句或较长的非谓语动词短语等等。这些附属成分常由逗号或分隔符号与句子隔开,且插在一个句子中间,使本来完整的句子被断开,因而增加句意理解的难度。分析长难句的基本方法是:首先,判断该句是简单句、并列句还是复合句;然后,找出句子的核心成分,分清主语和谓语,再分清句子附属成分。下面我们来谈谈几种长难句的处理方法技巧。重点
