连词是英语语法中至关重要的一部分，它们连接词语、短语或句子，构建更复杂、更流畅的表达。掌握连词的使用，能显著提升写作和口语的质量。本文将对英语中常见的连词进行总结，并结合实例进行分析，旨在帮助读者更好地理解和运用。

并列连词 (Coordinating Conjunctions)

并列连词用于连接具有相同语法功能的成分，例如两个名词、两个形容词或两个句子。最常见的并列连词有七个，可以用“FANBOYS”这个首字母缩写来记忆：for, and, nor, but, or, yet, so。

For：表示原因，相当于“because”。例如：He stayed inside, for it was raining heavily.

And：表示并列、补充。例如：She likes reading and writing.

Nor：表示也不，通常与“neither”连用。例如：Neither he nor she wants to go.

But：表示转折、对比。例如：He is poor, but he is happy.

Or：表示选择。例如：Would you like tea or coffee?

Yet：表示转折，语气比“but”稍弱。例如：She is tired, yet she continues working.

So：表示结果、所以。例如：It was late, so we went home.

并列连词的正确使用能使语句结构清晰，避免句子过于冗长。

从属连词 (Subordinating Conjunctions)

从属连词用于引导从句，使从句依附于主句，形成复合句。从属连词种类繁多，功能各异，常见的有以下几种：

时间连词：when, while, as, before, after, until, since, as soon as, whenever, no sooner…than, hardly…when。例如：When I saw him, he was reading a book. After the rain stops, we will go out.

原因连词：because, as, since, now that, considering that。例如：He couldn't come because he was ill. Since you are busy, I will do it myself.

条件连词：if, unless, as long as, provided that, on condition that。例如：If it rains, we will stay at home. You can go as long as you are careful.

让步连词：although, though, even though, even if, while, whereas。例如：Although it was raining, he went out. Even if you try your best, you may fail.

目的连词：so that, in order that, lest, for fear that。例如：He studied hard so that he could pass the exam. They locked the door lest someone should come in.

地点连词：where, wherever。例如：He lives where I used to live. You can sit wherever you like.

方式连词：as, as if, as though。例如：He speaks English as if he were a native speaker.

比较连词：than, as…as。例如：He is taller than I am. She is as beautiful as her sister.

正确选择从属连词，能准确表达句子之间的逻辑关系，使文章层次分明，逻辑严谨。

关联连词 (Correlative Conjunctions)

关联连词成对使用，连接句子中两个相关的部分。常见的关联连词有：

both…and：既…又… 例如：Both John and Mary are teachers.

either…or：要么…要么… 例如：You can choose either tea or coffee.

neither…nor：既不…也不… 例如：Neither he nor she is going to the party.

not only…but also：不仅…而且… 例如：He is not only intelligent but also hardworking.

whether…or：是…还是… 例如：I don't know whether he will come or not.

as…as：和…一样 例如：He is as tall as his father.

so…as：像…一样 （通常用于否定句）例如：He is not so tall as his father.

关联连词的使用能使句子的结构更对称，表达更清晰。

连词副词 (Conjunctive Adverbs)

连词副词具有连接句子或段落的作用，同时又具有副词的含义。常见的连词副词有：

however：然而，但是

therefore：因此，所以

moreover：此外，而且

furthermore：此外，而且

consequently：因此，结果

nevertheless：然而，尽管如此

otherwise：否则，不然

besides：此外，而且

indeed：的确，实际上

使用连词副词时，通常用分号或句号将其与前面的句子隔开，后面用逗号。例如：He was tired; however, he continued working. The weather was bad. Therefore, we stayed at home.

连词副词能使文章的过渡更加自然，逻辑更加流畅。
