13、主语和谓语可以由一个词或短语充当，也可以由两个或两个以上的词或短语充当，组成并列的主语或并列的谓语。除了主语和谓语之外，简单句中还可以有宾语、定语、状语、补语等。例：Spring is the best season for planting trees.春季是植树的最佳季节。After-class2.并列句含有两个或两个以上的独立分句的句子叫并列句。并列句中的常见的连词有：表示并列关系：and，not onlybut also，neithernor as well as等表示转折或对比关系：but，yet，while等。表示因果关系：for，so，thus，therefore等。表示选择关系

14、：or，eitheror等。例：I have travelled to many places，but I still want to visit more.我已经去过很多地方旅游，但是我还想游览更多的地方。After-class3.主从复合句（1）由一个主句和一个或一个以上的从句所构成的句子叫主从复合句。主句和从句都具有完整的主语和谓语，但从句只是句子的一个成分，不能独立存在。（2）主从复合句可分为定语从句、状语从句和名词性从句三大类。定语从句包括限制性定语从句和非限制性定语从句。状语从句包括时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句和方式状语从句等。名词性从句包括主语从句、宾语从句、表语从句和同位语从句。After-class4.并列复合句两个或两个以上由并列连接词连接的分句中至少有一个是主从复合句，这种句子称为并列复合句。After-class三、分析长句的方法1.找出句子主干一般而言，一个谓语形式的动词对应其动作的发出者（主语），可以根据谓语动词的意义来确定其主语。如果一个句子中出现两个或两个以上的谓语形式的动词，则该句可以是并列句或复合句（并列谓语动词的情况除外）2.寻找并列连词英语并列句或并列复合句都是由并列连词来连接的。找准这些并列连词，就能够弄懂句与句之间的逻辑关系。Thank you!
