在直角坐标系 $xOy$ 中，直线 $l$ 的参数方程为 $\text{{}\begin{array}{c}x=3+t,\\ y=\sqrt{3}t\end{array}$ （ $t$ 为参数），以原点为极点， $x$ 轴正半轴为极轴建立极坐标系，圆 $C$ 的极坐标方程为 $\rho =2\sqrt{3}\text{sin}\theta$ .

    Yesterday I stepped into a restaurant for lunch. As I was waiting my order to come, I noticed the old man in a wheelchair roll himself over to a table. No one and me seemed to notice him. I got up and go over to his table and asked if that I could get him something to drink. He smiled and said," Thank you. You are generously. I'd like any orange juice, please."When I was getting ready to leave, I walked by the old man's table to saying goodbye. He thanked me again and told me I had made his days, coming over and helping him out. I gave him a hug and told him he had made my day, either.
