8. (10 points) The calculation result of the expression $2013 \times \frac{2015}{2014}+2014 \times \frac{2016}{2015}+\frac{4029}{2014 \times 2015}$ is ( )
A. 4027
B. 4029
C. 2013
D. 2015
【Solution】Solution: $\frac{2015}{2014}>1$, then $2013 \times \frac{2015}{2014}>2013$; $\frac{2016}{2015}>1$, then $2014 \times \frac{2016}{2015}>2014$, $2013+2014=4027$, so $2013 \times \frac{2015}{2014}+2014 \times \frac{2016}{2015}+\frac{4029}{2014 \times 2015}>4027$. Among the options, only $4029>4027$, so this option must be correct. Therefore, the answer is: $B$.
