参考答案:
From elementary school to middle school, what has been learned is nothing but some basically common knowledge.Even what you are imparted during four-year university is also something superficial.Universities are usually referred to “the highest educational institution”which tends to breed the illusion that there is no more to learn after university.The research institutes of universities are just the places where knowledge is primarily studied.But even there you get only the first taste of learning where emphasis is on research methodology and practice.There is no satiety in study,and one's whole life is still not enough for learning.That's why ancient people continued with study even when their hair had turned hoary.However,indeed there was strong interest in this process.
