2、并列句(compound sentence)
英语的并列句一般情况下引不起巨大的阅读障碍,因为在分句之间往往有固定的连接词说明前后分句的关系。 这样的连接词有以and为代表的表示意义延伸的并列连词、以or为代表的表示选择概念的并列连词、以but为代表的表示转折的并列连词和表示原因的for四个类型。 遥种包括and, not only … but (also )…, neither ( nor) 。 第二种包括or , either … or …;第三种包括but , while , whereas等。 第四种只有一个for。 对此我们分别举一个例句说明问题:

(2)Not only is he himself interested in the subject but all his students are beginning to show an interest in it.
(3)Dr. Fisher neither loves the environment, nor is he accustomed to the weather.
