根据短文内容，选择正确答案。

阅读《安恩和奶牛》选段。

      ①在瓦尔普峡集市的牲口交易场上，站着一位老妇人和她的奶牛。她牵着那头孤独的奶牛悄悄地站在一边，也许是太腼腆害羞，也许是故意要吸引更多的人的注意。

      ②她身上穿着样式老掉牙的旧衣服，可是很干净；一条手染的蓝裙，还带着乡下染缸中的那股土味儿。一块棕褐色的绒线方披肩交叉地盖在她那干瘪瘪的胸上。她戴的那条头巾颜色褪得泛白，七皱八褶，好像是撂在抽屉里有了年头。脚上的木屐连后跟都磨平了，皮面上却抹了油，擦得锃亮。她那瘦骨嶙峋的双手拿着毛线针飞快地翩然起舞。除这几根针之外，在她的灰白的头发上另外还横插着一根。

      ③她站在那里，竖起耳朵凝神倾听着杂货摊上飘过来的音乐声，也不时抬头看看身边熙来攘往的人群和买卖交易的牲口。周围一片嘈杂喧嚣，马市上马儿嘶鸣，海滩上渔船卸货的在吆喝，马戏班鼓声咚咚，小丑们招摇地高声喊叫。然而她却站在那里晒着太阳，打着她的毛袜。哦，真是旁若无人，安闲得很。

      ④那头奶牛依偎在她的身边，头蹭着她的肘部，神情厌烦，腿脚僵硬地站在那里，翕动着嘴唇不断地反刍。这头奶牛已经上了年纪了，可这是一头很好的牲口，毛色鲜亮，连半根杂毛也没有，可以看得出来，它是出身真正高贵的纯粹良种。当然，要是存心找茬的话，那就是它的臀部和脊梁上长着一溜肉瘤，不过能挑得出来的瑕疵也就这么点儿了。它的浑圆的乳房胀得鼓鼓的，软绵绵、毛茸茸地垂在肚皮底下。它那黑白相间的美丽的牛角上点缀着几条环状的花纹。这是一头健壮结实的奶牛，曾经有过所有奶牛都有过的生活经历，它产下了小犊，然而连看它们一眼舔它们一下都没有来得及便被人带走了。这以后便吃着粗粝的草料，心甘情愿地把牛奶奉献出来。
