Today I want to talk about my ambition。I have always wanted to be an engineer because my father is an engineer。 I wanted to be a qualified scientific worker like my father。 Even when I was four or five years old， I tried to build various houses and palaces with my toy bricks。

When I was in school， I studied very hard。 I was one of the best students in my class。 My grades in every subject were excellent。

Now I am a college student。 I am doing my best to learn all I can that is necessary for an engineer to know about。 I am confident that I can make my contributions to our country in the near future with what I have learnt。
