Today, more and more people think about whether to travel alone or with friends. As to me, I’d like to travel alone. There are several reasons. 
现在，越来越多的人考虑是独自旅行还是和朋友一起。至于我，我喜欢独自旅行。原因如下：

Firstly, travelling is a process of decision making. When I travel alone, I can choose to visit my favorite place at first and stay there as long as I want. But as I travel with my friends, it's hard to decide where to eat and live. Not to mention where to visit at first. 
首先，旅行是一个做决定的过程。当我独自旅行的时候，我可以选择先去我最喜欢的地方，然后在那里想待多久就待多久。但是当我和朋友一起旅行时，经常会很难决定去哪里吃饭、住在哪里。更不用说先去哪里了。

Secondly, it's so difficult to book tickets and rooms for many people at a time, especially during long holidays. But if I travel alone, this problem can be easily solved. 
其次，很难在同一时间给许多人预订机票和房间，尤其是在长假期间。但是如果我独自旅行，这个问题就很容易解决了。

Thirdly, why do I want to travel? It's because I want to know more about the outside world. If I travel alone, it will be easier for me to communicate with the local people and get to know new culture and customs. More importantly, when I travel alone, I feel so free and independent. I can do anything I want and go wherever I like. I think it's a good way to develop my ability of independence. 
第三，为什么我想要去旅行？因为我想更多地了解外面的世界。如果我独自旅行，我将更容易与当地人交流，了解新的文化和习俗。更重要的是，当我独自旅行时，我感到很自由和独立。我可以做任何我想做的事，去任何我想去的地方。我认为这是培养我独立能力的好方法。

That's why I always enjoy travelling by myself. If I'm rich and free, I'd like to travel around our country to increase my knowledge, enrich my experience, and widen my horizon.
这就是为什么我总是喜欢独自旅行。如果我有钱也有自由，我想周游我国，增加我的知识，丰富我的经验，并拓宽我的视野。
