一并列句
由连词连接两个分句组成的句子叫并列句。这些分句平行并列,而且同等重要,能够独立成句。连接分句的有并列连词和主从连词。
并列连词:and, but, or, nor, for, whereas, while, either…or, neither…nor, not only…but(also).
主从连词:so, therefore, however, still, yet, then等。
并列句中的前后两句可以根据意思或分为四种关系。
(1)同等关系and/not only…but also/neither…nor,用连词and, not only…but also, neither…nor或者用逗号,有时也用分号连接两个简单句,构成并列句。
如:He could neither read nor write
He not only studies hard, but also likes sports.
(2)转折关系but, yet, still, while, when, 用连词but, yet, still, while, when连接两个句子时,前后两句为转折关系。
如:Tom was not there but his brother was (there).
There was no news, nevertheless, she went on hoping.
(3)选择关系or, either…or.
用连词or, either…or,连接两个句子时,前后两句为选择关系。
如:Either you didn’t understand this, or you were not careful enough
(4)因果关系for, so.
用连词for, so连接两个句子时,前后两句为因果关系。
如:He hurried, for it was getting dark.
He liked the book very much, so I gave it to him
二复合句
复合句中包括两个或更多的分句,其中一个分句是主句,其余的分句是从句。从句就是一个分句在主句中充当一个成分,如主语、表语、宾语、定语、状语等。
从句在句子中作什么成分就叫什么从句。
用作主语的从句叫作主语从句。主语从句一般都是作谓语动词的主语,偶尔也可以作分词的主语。
(1)  由what, whatever, whoever等代词引导主语从句。
如: What she likes is watching the children play
Whatever you have heard must be kept secret
