People’s whole life is not too long or too short. They have experienced many things in their life journey, such as, success, fail, happy, sad, and excited and so on. What about dreams? Some people think that they have so many things to deal with in the limit time. How can they spend time for dream? It is a waste of time. However, some people regard dreams are as important as their life. People can’t live without dream. In my opinion, I agree with the latter idea. 
人的一生不長也不短。在他們的人生旅途中他們會經歷很多事情，例如，成功，失敗，快樂，悲傷，激動等。那夢想呢？有些人會覺得他們有那么多東西要做而時間卻是有限的。哪還有時間花在夢想上？純屬浪費時間。然而，有些人把夢想當作自己的生命一樣重要。沒有了夢想人們難以生存。在我看來，我同意后者的觀點。
First of all, dreams provide life motivation for human beings. If a person has a dream, he will try his best to take every chance to reach it. Even though he will meet many difficulties on the way, even has to give up, but he will renerve in the end. It is because he has dreams, and he has the desire to see the day his dream come true. So no matter what obstacle he meets, he has the motivation to overcome. This is the power of dreams.
首先，夢想為人們提供了生活的動機。如果一個有夢想的人，他會努力抓住每一個實現夢想的機會。在這路上雖然會遇到很多困難，甚至被逼放棄，但是最后他會重新振作的。因為他有夢想，他希望有夢想成真的一天。所以無論遇到什么障礙，他都會有克服的動機。這就是夢想的力量。
In addition, life without dreams is meaningless. We often see that when someone talks about his dream, his face is full of smile. It is because dreams give him hope and fun. No matter the dream is easy to make it or not, when the people think of it, they will have the beautiful vision to fight for. But if a person who don’t have a dream, he would not know what he should do and can do. His life is confused and meaningless.
此外，沒有夢想的生活是沒有意義的。我們經常看到當別人談論他們夢想的時候，他的臉上是堆滿笑容的。這是因為夢想給了他希望和樂趣。不管實現夢想的難易程度是多少，只要人們想起來的時候，就會為了這美好的愿景去奮斗。但是如果一個沒有夢想的人，他會不知道應該做什么或者是能做什么。他的生活會充滿了困惑和無意義。
In a word, dreams look like the lighthouse in the ocean. It gives people motivation and the meaning of their journey. It is so significant that everyone needs dreams. 
總之，夢想就像是大海里的燈塔，給予人們動力和人生旅途的意義。它是那么的重要，所以每個人都需要夢想。
