    (1)我们生活在一个充满竞争的世界里. Our parents compete (竞争) with others in their offices, our

brothers and sisters compete with others in their colleges, and we compete with our classmates in school.

her own advantages (优点). Don't look at things from a single (单个的) point of view. Try to discover your

own advantages, and believe that you can do better than others in those ways. 

than you. (2)Remember that self-confidence is the first step to success. Believe in yourselves, and you will

be successful one day.
