A conjunction is a word that grammatically connects two words, phrases, or clauses together. The most common examples are words like ‘and’ and ‘but’.
连词在语法上连接两个词，短语或者句子。最常见的连词是‘and’和‘but’。
For example, ‘I took the subway, and got off at 96th Street.’ Or, ‘I took the subway, but there was a delay.’ However, conjunctions can come in many forms with many different functions.
例如，‘我上了地铁，然后在第96大街下车了’或者‘我乘地铁了，但是我还是耽搁了’。然而，连词有多种形式，自然也有不同的作用。
They’re a part of speech that can be broken down into several categories, and we’ll explore each one in depth with examples.
连词是一种词性，可以被分成好多种类，我们将附以例子来深入探讨每一种。
Conjunctions can primarily be broken down into three categories:
连词主要可以分成三种：
Coordinating conjunctions
并列连词
Correlative conjunctions
关联连词
Subordinating conjunctions
从属连词
Coordinating conjunctions always come between two clauses in order to connect them. These are two ideas that are related and can therefore be placed into one longer sentence.
并列连词位于两个从句中间，用来连接两个句子。并列连词连接的是两种意义相近的想法，有了并列连词的连接，两个短句就可以被合写成一个较长的句子。
A coordinating conjunction is a conjunction like “and” and “but.” It joins together words, phrases, or clauses that are grammatically equal. The seven coordinating conjunctions are:

The seven coordinating conjunctions can be remembered using the acronym: FANBOYS

Using the word “for” like this, however, can sound a bit formal and unnatural in spoken English. Instead, it’s better to use subordinating conjunctions like “because” or “since,” which we’ll discuss later. Meanwhile, the word “for” can take different usages as a preposition, not a conjunction. For example:
在英语口语中这样使用‘for’听起来有点正式甚至不自然。相反，使用从属连词‘because’或者‘since’可能会好一点，这一点后期我们会进行讨论。同时‘for’这个词作为介词用法完全不一样。例如：
