Significant differences were shown in the observation times of females during the peak and the middle of the reproductive season at different densities. The observation time of the females was much longer in low density population than that in high density population. For males, there was no significant difference in observation time between or among population densities. At both low and high population densities significant seasonal variation was found in the duration and frequency of male plateau pikas observation behavior, nor was that of females.

Listening and reading can be regarded as input and accumulating. They belong to observation-based learning. You should try your best to imitate very pronunciation and intonation, every word and sentence. You should imitate and absorb from the rough to the subtle with a let-go attitude. It's a personal matter to determine when you should have rest for a period of time and let imported language materials can be processed in your brain according to your own character. When you feel that your head is stuffed with many language materials just like a teacup full of water, it will overflow if you continue to pour water into it. OK, grasp that turning point and begin to rest.

听和读，是输入和积累，也可以说是基于观察的学习(observation-based learning)，应该尽力模仿，每个音调和语调，每个字词和句子，从粗到细地模仿和吸收，要抱着一种不求甚解、顺其自然的态度才好，究竟什么时候该休息一段时间，让输入的语言材料在大脑内部按照个人的特点进行加工处理，这完全是因人而异的事情，当你觉得你的头脑被很多语言材料充满，就像茶杯已经倒满了水，如果再继续往茶杯里倒水，只会溢出来，好了，抓住那个临界点，开始休息。
