答案：
Optimism is important in all aspects of our life. If you can change your mind from pessimism, you can change your life.
Up to the beginning of Senior Grade Two, I did poorly in my English but I didn’t give in because I was always encouraged by both the people around me and myself. I kept practicing speaking, listening, reading and writing. When I was fed up with reading or writing, I usually entertained myself by reading some interesting English stories, jokes and humors or seeing English films. When I had some trouble in reciting or memorizing, I tried to amuse myself by playing word games or singing English songs. By this means, I always made myself cheerful and optimistic, full of splendid and colorful dreams of future. I kept practicing. Gradually, I made progress in my English. .
Thanks to the optimism, I have become one of the top students in my class by now.
题目分析：本文写作属于提出主题，然后对主题进行发挥题型。这类题型给学生腾出了很宽的写作空间。对于本文的写作，首先说明乐观的重要性，然后结合自己生活中的事例，比如自己在学英语过程中自己是如何通过积极的做法来保持乐观的，再说明这种做法给我的学习带了很大的好处，最终我得以成功或提高。最后进行一句话的总结，这样文章就比较完美了。
点评：对于高三的写作，写的过程中注意避免使用中式英文，要对所写的句子变换表达，对于表达内容层次时需要使用平时积累的层次关系的短语，多使用被动，倒装、虚拟来提升作文的美度。在平时写作时应该多进行阅读，对阅读过程中写的好的表达要进行积累，并且学以致用，勤积累，多背诵，这样才能作文才能稳步的提升。
