求翻译：My dream is to be a scientist because I like challenging tasks and would really want to research and discover new solutions that could cure many illness that are currently terminal. I feel a sense of responsibility to keep fighting with bacterias that kills many people such as the SARS virus. I would really want to achieve my dream and I am preparing to achieving and will be doing this by working hard at school right now. Also I will start to participate in other biological interest projects to help me decide the area I want to specialise in.是什么意思？
