阅读下列短文，从每题所给的四个选项（A、B、C和D）中选出最佳选项。

    Are you sorry for not traveling during the National Day? If you stay at home at that time, I think you are very lucky. Why? Because there are too many people everywhere. In many places of interest in China, it's too crowded to do anything.

    Look at the picture. It was too crowded on the Great Wall on October 1st, 2015. You even couldn't take photos for you or your friends. All what we could see were people. It was reported that there were about twenty people every meter on the Great Wall. My friends told me they could see nothing but many people on the Great Wall. "We couldn't walk if the people in front of us didn't walk," he said. He showed us a photo on the Great Wall. In the photo, we hardly found him out, there were too many people.

    So some people give the advice that we should not have the gold week any more. But other people say no about this advice. What's your idea of it? Are you sorry now for not traveling during the gold week? I love staying at home more than traveling next National Day.

央视《朗读者》第二期节目主持人的开场白：“草，在结它的种子；风，在摇它的叶子；我们站着，不说话，就十分美好。”在顾城的诗里，陪伴就是这样简单而美好。而在我们每一个人的生命里，会遇到各种各样的陪伴，比如说这会儿，你我之间是一段短暂的陪伴；比如说我们的学生时代，和我们的同学，那是几年的陪伴；还有一种陪伴，是生命里血脉注定一生的陪伴，那是我们和父母，和孩子之间的陪伴。在这个世界上没有一个人是孤岛，失去了陪伴，也失去了生存的意义，所以陪伴也是一种力量。

你的世界也处处有陪伴的倩影，你也有许多时候享受陪伴的美好，他人给予你的，你给予他人的。请你以“陪伴”为题，写一篇文章。

要求：①立意自定，感情真挚，不得抄袭；②除诗歌外，文体不限；③不少于600字；④文中不得出现真实的人名、校名。
