You can compare your feelings or experiences with your primary school teachers and high school teachers. You might mention the teaching style, personality, or the relationship you had with them. It's okay to say you liked both, or that you preferred one over the other, but try to give a reason for your answer.
你可以比较一下你对小学老师和中学老师的感受或经历。你可以提到他们的教学风格、个性,或者你们之间的关系。你可以说你喜欢他们两个中的任何一个,或者更喜欢其中一个,但请尽量给出你的原因。
