某校去年有学生1 000名，今年比去年增加了4.4%，其中住宿学生增加了6%，走读生减少了2%。若设该校去年有住宿学生有x名，走读学生有y名，则根据题意可得方程组（      ）

A：$\left\{\begin{array}{c}x+y=1000\\ \frac{6}{100}x-\frac{2}{100}y=\frac{4.4}{100}\times 1000\end{array}\right.$

B：$\left\{\begin{array}{c}x+y=1000\\ \frac{106}{100}x-\frac{102}{100}y=\left(1+\frac{4.4}{100}\right)\times 1000\end{array}\right.$

C：$\left\{\begin{array}{c}x+y=1000\\ \frac{6}{100}x+\frac{2}{100}y=\frac{4.4}{100}\times 1000\end{array}\right.$

D：$\left\{\begin{array}{c}x+y=1000\\ \frac{106}{100}x+\frac{102}{100}y=\left(1+\frac{4.4}{100}\right)\times 1000\end{array}\right.$
