1. (8 points) The calculation result of the expression $\frac{25 \times 8+1 \div \frac{5}{7}}{2014-201.4 \times 2}$ is ( )
A. $\frac{1}{5}$
B. $\frac{1}{6}$
C. $\frac{1}{7}$
D. $\frac{1}{8}$
【Solution】Solve: $\frac{25 \times 8+1 \div \frac{5}{7}}{2014-201.4 \times 2}$
$$
\begin{array}{l}
=\frac{200+1.4}{201.4 \times 10+201.4 \times 2} \\
=\frac{201.4}{201.4 \times(10-2)} \\
=\frac{1}{8}
\end{array}
$$

Therefore, the correct choice is: D.
