1. (10 points) Calculate: $\frac{2012 \times\left(2010^{2}-9\right) \times 2014}{2007 \times\left(2013^{2}-1\right)}=$
【Analysis】First, simplify the numerator and denominator of the complex fraction separately according to the difference of squares formula, and then solve it.
【Solution】Solve: $\frac{2012 \times\left(2010^{2}-9\right) \times 2014}{2007 \times\left(2013^{2}-1\right)}$
$$
\begin{array}{l}
=\frac{2012 \times(2010+3) \times(2010-3) \times 2014}{2007 \times(2013+1) \times(2013-1)} \\
=\frac{2012 \times 2013 \times 2007 \times 2014}{2007 \times 2014 \times 2012} \\
=2013
\end{array}
$$

Therefore, the answer is: 2013.
