补充翻译：
学习是个循序渐进、长期的过程，我会在知识的宝库中不断探索，丰富自我。去年暑假，我参加了职场体验活动，我从中受益匪浅，获得了真正的社会技能，这也正是这种活动的意义所在吧。Learning is a gradual and long-term process. I will explore and enrich myslef in the treasury of knowledge. Last summer vocation, I participated in a career experience activity and really learned a lot, acquiring practical society techniques. This is what the meaning of the activity must be.
除了课外实践活动，我还通过课外阅读来净化自己的灵魂。正如凯勒所说：一本好书像一艘船，带领我们从狭隘的地方驶向无限广阔的生活海洋。所以我挑选了课外名著如《傲慢与偏见》《红高粱》等图书开阔我的视野。Besides after-class practical activity, my soul gets purified through extracurricular reading. Just as Caylor said, a new book is like a boat steering people from a narrow stream to a vast ocean of life．So I specially chose masterpieces like Pride and Prejudice, Red Sorghum, etc to expand/widen my vision.
我每天都锻炼身体，保持健康和充满活力。毕竟，我们还是要德智体美全面发展。
I do exercises every day to keep fit and vigorous. All in all, we shall make all round development of morality, intelligence, physique and art, etc.
