上一次我们为大家介绍了数学语句中表示连接关系的连词。今天易伯华国际教育小A要说的是：隐含或解释(Implications or Explanations)。因果关系，简单直白点，就是因为……所以……的那些事。说到因为和所以，每个人脑海里一下子闪出来的一定是because和so，非常好!但如果通篇都是because和so，尤其是像数学这种逻辑性超强的学科来说，这两个词会不会累到罢工了呢?来看下面的例子吧：

1. The gradient of astraight line is positive.

直线的斜率是正数。

2. The straight line isincreasing.

直线是上升的。

as/because/since (最常见的用法)

As (Because, Since) the gradient of a straight line is positive, this line isincreasing.

· due to (比用as更强调)

The straight line isincreasing due to its positivegradient.

· in view of/owing to/on account of (比用as更强调)

In view of (Owing to, On account of) positive gradient of astraight line, it is increasing.

· given (所述条件不可避免的结果)

Given positive gradient of a straight line, it is increasing.

· it follows that (对原因给出比用as更多的强调)

The gradient of astraight line is positive. It follows that this line is increasing.

· consequently/therefore/thus (强调性居于as和it follows that之间。Consequently和therefore在句子开头比thus更合适)

The gradient of astraight line is positive and consequently (therefore, thus) this line is increasing.

大家是不是很常用because和since呢?这当然没有问题。但当一页纸里有过多的because，便会使文章读起来生硬，所以，我们要学会合理的应用as，due to，it follows that等连接词或短语。

同样的情况也出现在therefore和hence的运用中。我们也可以使用不同的说法，如consequently和it follows from ... that，以免重复。另外，because后面跟的是从句，若只跟名词或动名词，则用because of。
