赏析诗歌，回答下列各题。
                                                                                                      行路难  (李白)
                                                                                    金樽清酒斗十千，玉盘珍羞直万钱。
                                                                                    停杯投箸不能食，拔剑回顾心茫然。
                                                                                    欲渡黄河冰塞川，将登太行雪满山。
                                                                                    闲来垂钓碧溪上，忽复乘舟梦日边。
                                                                                    行路难！行路难！多歧路，今安在？
                                                                                     长风破浪会有时，直挂云帆济沧海。

在平面直角坐标系 $xOy$ 中，直线 $l$ 的参数方程为 $\text{{}\begin{array}{c}x=-\frac{\sqrt{3}}{2}t,\\ y=1+\frac{1}{2}t,\end{array}$ （ $t$ 为参数），以原点为极点， $x$ 轴正半轴为极轴建立极坐标系，曲线 $C_1$ 的方程为 $\rho =\frac{36}{4\sqrt{3}\text{sin}\theta -12\text{cos}\theta -\rho }$ ，定点 $M\left(6,0\right)$ ，点 $N$ 是曲线 $C_1$ 上的动点， $Q$ 为 $MN$ 的中点.

    James Cook, at the age of forty, was sent by England to explore the Pacific Ocean. On his third voyage, as captain in charge of two ships, the Discovery and the Revolution, he came upon a group of unknown islands which he named the Sandwich Islands after his friend, the Earl (伯爵) of Sandwich. Today the islands are known at the Hawaiian Islands.

    When Cook sailed into a protected bay (海湾) of one of the larger islands, the natives greeted him with curiosity and respect. Some historians said that the islanders welcomed him, believing he was the god, protector of peace and agriculture.

    The islanders were short, strong people with a very well-organized social system. The men fished and raised crops. The women prepared for the children and made clothing for the men and short skirts for the women.
