Summary
1.含 义
并列复合句
2.构 成
并列复合句是指由并列连词and/but/or等把两个
或两个以上的简单句连在一起而构成的句子。
简单句 + 并列连词 + 简单句
3.常见并列连词及其用法
1. 表并列关系：and, not only…but also, neither…nor
2. 表选择关系：or, otherwise, or else, either
3. 表转折关系：but, yet, still, however
4. 说明原因： for
5. 表示结果： so
1. 表并列
用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等, and所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系。若第一个
分句是祈使句,那么第二个分句用将来时。
and
e.g. He gave her a painting as a present, and she liked it so much.
not only…but also (就近原则)
e.g. She not only plays well, but also writes music.
Not only did he make a promise, but also he kept it.
neither...nor...(就近原则)
e.g. Neither has she changed her mind, nor will she do so.
He neither likes fiction, nor does he like poetry
【注意】neither...nor...连接两个分句，并且neither位于句首时，
两个分句的主、谓语都要部分倒装。
2. 表选择
表示在两者之间选择一个, 常用的连接词有or, or else, otherwise, either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。
or
e.g. She must be joking, or she is mad.
otherwise
e.g. You'd better go now, otherwise you'll miss the train.
or else
e.g. The book must be here, or else you've lost it.
either…or…
e.g. He either watches TV or reads books in the evening.
3. 表转折
表明两个概念彼此有矛盾、相反或者转折, 常用的连接词有 but, yet, still, however等, 前后分句时态一致。
but
e.g. The machine is old, but it is in good order.
yet
e.g. It is strange, yet it is true.
still
e.g. Although we are very tired, still we shall work.
however
e.g. I'd like to go with you, however, my hands are full.
4. 说明原因
说明原因, 用连接词for, 前后分句时态一致。
for
e.g. She must be depressed, for she failed the exam.
e.g. It's going to rain, for my knee joints are aching.
5. 表示结果
表示结果, 用连接词so, 前后分句时态一致。
so
e.g. I had a headache, so I went to bed.
e.g. It rained, so the sports meeting was postponed.
4. 使用并列复合句要注意的几种情况
(1) 并列复合句有时可不用连词, 而用分号隔开(前后句之间的关系
须相当紧密)。
e.g. We finished all day; we did not catch a single fish.
(2) 并列连词前后的简单句如果有相同部分, 则后句的相同部分
可以省略。
e.g. Snoopy lives in his own world and (Snoopy) finds real life hard
to understand.
