大学英语语法 并列与从属

第十一章并列与从属并列在大多数情况下，并列结构由并列连词连接而成。

不同的并列连词有不同的含义，因此被连接的成分就具有不同的关系。

我们需要注意的是，在一个特定的句法环境中，一个并列连接词与另一并列连接词所起作用的方式是不同的。

所以我们需要辨别并列连接词及其用法。

并列连接词最常见的并列连接词是and，or和but，它们被称为“中心并列连接词”或“纯粹并列连接词”，因为他们主要用来连接在同一句法层上的语言单位。

其他并列连接词具有中心并列连接词的一部分句法和语义特征。

“关联并列连接词”几乎总是连接两个并列成分。

此外，还有几个连接词被称为“半并列连接词”，因为它们有时用作并列连接词。

还有一类称为“边际并列连接词”，因为它们有时用作并列连接词，有时用作从属连接词或介词。

常用的并列连接词如下：中心并列连接词：and，or，but关联并列连接词：both… and, either.., or, not...but, neither...nor, not only.., but also半并列连接词：nor, so, yet边际并列连接词：as well as，as much as，rather than，more than尽管上述列举不够详尽，但这些并列连接词在连接句子成份方面起了重要作用d and，or和but是中心并列连接词，不仅因为它们用法如此，还因为它们代表了并列成分之间的三种基本关系：列举、选择和对比。

其他并列连接词相对于这三个并列连接词就边缘些。

但是，正如我们很快就会看到的那样，一个并列连接词在不同的词境中代表不同的关系，即使中心并列连接词在语义上也不那么纯粹。

and和有关并列连接词并列连接词and常用来连接一组并列成分：结构是A and B。

其他能起类似作用的并列连接词有：both…and，not only…but also，as well as, not.., or,not.., nor,neither.., nor.例如：①I gave her a cup of tea and some biscuits.我给她一杯茶和一些饼干。

It was not until I came here that I realized this place was famous for not only its beauty but also its weather. 直到我来到这里，我才意识到这个地方之所以出名不仅是因为它的漂亮还因为它的天气。

特别要注意“祈使句+and / or+陈述句”这类句式。

如：Stand over there and then you'll be able to see it better. 站到那儿去，你就能看得更清楚了。

2.表示转折或对比的并列连词表示转折或对比的.并列连词主要有but, yet, while。

如：Sophia waited for a reply, but none came. 索菲亚等候答复，但没有任何答复。

I woke up with a bad headache, yet by the evening the pain had gone. 我醒来时，头疼得厉害，但到了晚上，疼痛就消失了。

特别要注意while一词。

In some places women are expected to earn money while men work at home and raise their children. 在一些地方，妇女要去赚钱，而男人操持家务并照顾孩子。

并列连词和从属连词的用法归纳在语言表达中，连词起着连接不同部分和句子的重要作用。

其中，并列连词和从属连词是两类常见的连词。

本文将对并列连词和从属连词的用法进行归纳和总结，并给出一些例子，以帮助读者更好地理解和应用。

并列连词和从属连词的区别和用法并列连词和从属连词在英语中是常用的连接词，它们在句子中起到了承接、转折、因果等不同的连接作用。

本文将对并列连词和从属连词的区别和用法进行详细介绍。

一、并列连词的特点及用法并列连词指的是连接两个或多个并列成分的连词，常见的并列连词包括：and，but，or，nor等。

并列连词主要有以下几个特点：1. 并列连词的作用是连接意义相近或平行的成分，使得句子更加连贯和完整。

2. 从属连词引导的从句往往依赖于主句，没有主句则从句无法独立成句。

3. 从属连词引导的从句可以出现在主句之前、之后或者中间。

英语基础语法连词连词分为并列连词和从属连词两大类。

并列连词是连接主语与主语，谓语与谓语，句子与句子，分词与分词的词，它要求前后两部分有相同的形式和语法作用；而从属连词一般连接主句与从句，从句形式有名词性从句，定语从句和状语从句等。

1．并列连词并列连词可用来连接词与词，词组与词组，分句与分句。

常用的并列连词有：and(和)，as well as(既……又)，both... and(不但……而且)，not only... but also(不但……而且)，not ...but(不是……而是)，neither...nor(既不……也不)，either... or(不是……就是)，or(或者)，but (但是)，yet(然而)，for(因为)，so(所以)，while(而)，when(这时)等。

并列连词与从属连词的区别与用法详解连词是连接词组、短语或句子的词语，其中，并列连词和从属连词是常用的两种类型。

本文将详细解释这两种连词的区别与用法。

一、并列连词（Coordinating Conjunctions）并列连词用于连接同等重要的词组、短语或句子。

以下是并列连词的主要用法：1. 连接两个主题相同或相似的词组或短语：- I like to read books and watch movies in my free time.我喜欢在空闲的时间里读书和看电影。

2. 连接两个具有相同功能的句子：- She is smart, but he is intelligent.她很聪明，但他很有才智。

英语语法知识——连词连词是一种起连接作用的词。

连词是虚词，不能单独作句子成分，只能起连接单词、短语或句子（包括从句与分句）的作用。

可分为并列连词与从属连词。

一、并列连词的用法1．并列连词and的用法and可以连接两个的词，多用于肯定句中。

连接两个句子，表示因果、对比、条件、假设、目的等。

例如：（连接两个动词如go, come等表示目的）去取Go andfetch something to eat.些吃的东西来。

andLily is fond of sports.Mary likes music玛丽喜欢音乐，莉莉爱好体育运动。

（对比）One more week and we’ll accomplish the task.再一星期，我们就完成任务。

（条件）的用法2．并列连词both…and,not only…but also, as well as①both…and意为：“不但…而且…；既…又…”，是并列连词，可以并列主语、宾语、表语、状语、谓语等成份。

并列主语时谓语动词用复数形式。

not o nly…but also 可以连接两个句子，not only 位于句首时， not only 后的句子要倒装。

并列连词和从属连词的用法总结在英语的语法中，连词是连接词语、短语或句子的重要工具。

其中，并列连词和从属连词是最常见的两类连词。

本文将对并列连词和从属连词的用法进行总结，并对其在句子中的使用提供一些示例。

一、并列连词的用法并列连词用于连接具有平行关系的词、短语或句子。

常见的并列连词有"and"、"but"、"or"、"so"、"for"等。

以下是并列连词的几种用法：1. 连接两个相同成分：使用并列连词将两个名词、形容词、副词等连接在一起，表达相同的含义。

例：I like coffee and tea.He is tall but kind.She runs fast and gracefully.2. 连接两个独立句子：使用并列连词将两个完整的句子连接在一起，形成复合句。

例：I love reading, but my brother prefers watching TV.She is a doctor, and he is a teacher.3. 连接并列分句：使用并列连词将两个平行结构的分句连接在一起。

例：He is not at home, so I left him a message.You can study hard, or you can party all night.二、从属连词的用法从属连词用于引导从句，从句与主句之间形成因果、条件、目的、时间等关系。

常见的从属连词有"if"、"because"、"while"、"since"等。

以下是从属连词的几种用法：1. 引导条件从句：使用从属连词表达一个条件，明确主句的发生依赖于从句的情况。

例：If it rains tomorrow, we will stay at home.Unless you study hard, you will fail the exam.2. 引导原因从句：使用从属连词表达主句发生的原因。

并列连词和从属连词连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。

连词主要可分为两类:并列连词和从属连词。

并列连词用来连接平行的词、词组和分句.如：and，but, or, nor, so, therefore, yet, however, for, hence，as well as，both…and，not only…but also, either…or，neither…nor，(and）then等等。

并列连词并列连词用来连接属于同一层次并具有相同句法功能的词；短语或句子。

or , neither。

nor ，not only.。

and，whether.。

.or 等;介于并列连词与从属连词之间的连词；介于并列连词与从属连词或介词之间的结构如as well as , as much as, rather than , more than, no less than 等；此外还有些’半连接词’，一些语法学家把它们称为连接副词，如nevertheless, however, meanwhile, otherwise，likewise 等，它们在句中做连接性状语。

这类连词主要是从逻辑上，而不是从形式上连接句子，其关系比较松散。

英语语法什么是连词连词在英语语法中扮演着非常重要的角色。

它们用于连接词、短语、句子和句子之间的关系，帮助我们组织思维和表达意思。

在本篇文章中，我将详细介绍连词的不同类型、用法和一些重要的注意事项。

一、连词的定义和分类连词是一类词性，用于连接词、短语、句子和句子之间的关系。

根据其功能和用法，连词可分为以下几类：1. 并列连词（Coordinating Conjunctions）：用于连接同等重要的词、短语、句子或句子之间的关系。

常见的并列连词有"and"、"but"、"or"、"nor"、"for"、"yet"等。

2. 从属连词（Subordinating Conjunctions）：用于引导从属从句，并将从属从句与主句连接起来。

从属连词在句子中起到连接主从句的作用。

常见的从属连词有"although"、"because"、"if"、"when"、"while"等。

3. 连接副词（Correlative Conjunctions）：由两个或多个词组成，用于连接相同类型的词、短语或句子。

常见的连接副词有"either...or"、"neither...nor"、"both...and"、"not only...but also"等。

4. 连接代词（Relative Pronouns）：既是代词，又是连词，引导定语从句，并将定语从句与主句连接起来。

常见的连接代词有"who"、"whom"、"whose"、"which"、"that"等。

并列连词和从属连词的正确连接方式一、引言连词作为连接词组、短语和句子的重要工具，在英语写作中扮演着至关重要的角色。

并列连词和从属连词是其中两种常见的连接方式。

本文将详细介绍并列连词和从属连词的正确使用方式，以帮助读者提升英语写作的表达能力。

二、并列连词并列连词用于连接两个具有相同重要性的词、短语或句子，将它们并列起来，使句子结构更为复杂且具有层次感。

1. 并列连词的种类常见的并列连词有：and、but、or、nor、so、yet等。

这些连词在连接词、短语或句子时，需要注意其正确的使用场景。

2. 并列连词的正确使用方式2.1 使用andand通常用于连接相同类型、意义类似的词、短语或句子。

例如：- I like both apples and oranges.（我喜欢苹果和橙子。

）- He is smart and hardworking.（他既聪明又勤奋。

）2.2 使用butbut用于表示转折、对比或排除。

例如：- She is intelligent but sometimes lazy.（她聪明，但有时候懒惰。

）- I want to go to the party, but I have to finish my homework first.（我想去派对，但我必须先完成我的作业。

）2.3 使用or、noror用于表示选择关系，而nor表示否定选择。

例如：- You can choose coffee or tea.（你可以选择咖啡或茶。

）- He doesn't like vegetables, nor does he like fruits.（他不喜欢蔬菜，也不喜欢水果。

）2.4 使用soso通常用于表示因果关系、结果或推理。

例如：- He studied hard, so he passed the exam.（他学习很努力，所以他通过了考试。

）- It was raining, so we stayed at home.（下雨了，所以我们待在家里。

1、连词的含义：连接词与词、短语与短语、或引导从句的词叫连接词。

2、连词的分类：连词分为并列连接词和从属连接词两种。

1、并列连接词连接并列的词、短语、从句或句子。

常见的并列连接词有：and(和),but(但是),or(或者,否则),nor(也不), so(所以), however(然而,无论如何),for(因为),still(可是),as well as(也),both..and...(...和...), not only ...but also...(不但…而且…), either… or…(或…或…),neither… nor…(既不…也不…)等。

2、从属连接词用于引导从句,常见的从属连接词有：when(当…时候), while(正当…时候), after(在…之后), before(在…之前), since(自从), until(直到), although/though(虽然), if(假如), as(如…一样；由于), as …as…(和…一样), as far as(就…而言), as long as(只要), as soon as(一…就…), even if(即使), because(因为), unless (除非), than(比…), whether (是否…), in order that…(为了), so…that…(如此…以致), so that…(以便), now that…(现在既然), by the time…(到…时候), every time…(每当), as if…(仿佛),no matter when(或whenever)(无论何时),no matter where(或wherever)(无论在哪里)等。

［辨析］(1)because、as、since、for的用法：because(因为)表示原因的语气最强,常表示必然的因果关系,从句一般放在主句后面；另外,回答why的问句只能用because. as(因为)表示一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句可以放在句首也可以放在句尾。
