College life is a crucial period for college students to form a systematic world outlook, outlook on life and values. First of all, college students should focus on learning. No matter how society or classmates around us reject learning, don't forget that we are still in the stage of accumulating knowledge. After leaving campus, we won't have such time, atmosphere and energy to study. However, we should also understand that learning does not mean memorizing textbooks, but learning everything that may be useful or interesting in our future. You know, when you are at school, you will feel that you have nothing but a lot of time. When you are in the society, you will find that you lack nothing, and you will lack time for study.

(A) establish a pioneering and innovative attitude towards life

(B) establish a positive and optimistic attitude towards life

(C) establish an honest and modest attitude towards life
