The time and frequency of the polecat searching different preys and burrows were nearly the same. The polecat attacked virtually all prey offered and thus exhibited opportunistic foraging behaviour. However, it did not captured all prey with equal sequence. It first captured the zokor, then the pika and last for the root vole. In addition to using the typical musteline killing method of biting the nape of the neck, the polecat evolved a variety of killing methods suited to a range of prey types depending on the activity, size and anti-predation ability of prey. The zokor was bitten on the head, whereas the pika was killed by bites to the head or throat and the root vole was killed by bites to the head or chest. The time polecats pursued the root vole was the longest, followed by that used in pursuing the pika and the zokor.

实验结果表明：艾虎对三种猎物的搜寻时间和搜寻频次基本一致，在搜寻猎物的过程中并非已知洞道系统中所存在的食物信息，是一种机会主义的捕食者；艾虎除了具有典型鼬科动物捕杀猎物的方法外，能够根据猎物的大小、活动性和反捕食能力采用不同的捕杀方法，在捕杀猎物的过程中首先捕杀高原鼢鼠，其致死部位全部为头部，其次捕杀高原鼠兔，其致死部位除了头部外，明显增加了颈部的比例，最后捕杀根田鼠，其致死部位主要是头部和胸部；艾虎在捕杀猎物的过程中，追击根田鼠的时间最多，追击鼢鼠的时间最少，而用于捕杀根田鼠的时间最少，用于捕杀鼢鼠的时间最多，艾虎捕杀高原鼠兔后单位时间内获得的能量值最大，其次为捕杀高原鼢鼠，而捕杀根田鼠后单位时间内活动的能量值最小。

Chapter 2 centres around the spiritual contents of her works. It penetrates through the skin to their core, that is, the tragic sense. Her works take the most ordinary people as characters. Unexpectable elements befall on these people, change their fate considerably. The helplessness of being fooled by destiny overshadows most of her works, leaving readers sign in vain. Then, her portrayal of characters bears a tinge of rootlessness, unsteadiness loneliness, filling the works with deep pensive mood. And finally, she exposes the ugliness of man from this covering of brilliance. Man dares not face his true being. What he shows and sees of himself tends to be his bright side. But his ugly side steels out, which gives himself a deadly blow.

第二章围绕作品的精神内蕴展开论述，侧重于由表及里的层层挖掘，悲剧意识构成王安忆作品精神内蕴的核心，其作品多写芸芸众生，在展现这些人的人生际遇时，难以预料的偶然因素总是改变着他们的命运，宿命感使作品笼罩在虚无的阴影之中，令人怅然；其次作家在写人物时，那种无根的漂泊感、孤独感，使作品有着深深的悲凉意蕴；再次就是对隐藏在绚烂表象之下的人的丑陋本质的发现，人总是无法面对自己真实的存在，看到的或表现出的总是冠冕堂皇的一面，但是那丑陋的一面总会在不经意中呈现出来，给人以毁灭的打击。
