ALevel专业文章写作中的连词（一）并列连词

同学们在学习A Level的过程中，一定会遇到写的问题：数学和物理的解题过程，经济学中的论文，等等。这里的写，不仅仅是数字和符号的问题。如何才能清晰明了的表达自己的意思，也决定了在考试中能不能得到更高的分数。

       A Level文章写作中的连词。

　　在这个系列中，Richard老师将提供一些常用的连接词组、短语及相邻句子的连接词在A Level文章中的用法。这些表达特殊意义的语言成分可以是单词，也可以是短语。

　　首先我们来看：组合(Combinations)。Richard老师将用一个简单的数学例子来说明，看看如何用连词将下面两个论断组合起来：

　　2. Absolute values are non-negative numbers.

　　and (不强调其中任何一方)

　　Squares and absolute values are non-negative numbers.

　　Squares, as well as absolute values, are non-negative numbers.

　　not only … but also (强调有多于一个可能性)

　　Not only squares but also absolute values are non-negative numbers.

　　apart from/in addition to (强调多于一种方法;比用also稍微更强调平方，但比用not only … but also强调弱些)
