Reading: 动物有固定的patterns of behavior。 Listening: 1、一种小鱼：male fish会do attack dance to the finish entering its territory 而且是有red mark的，如果没有red mark就不会2、goose：female鹅生过蛋后会move its head back and forth，但是当它的egg被moved away 以后，它仍然这样。问题是：讲一讲什么是动物的这种惯性行为(文中用了缩写，好像是AFS 还是FAS记不清了)，然后讲讲lecture中间的例子如何证明的。
The reading material is about animal behavior. It is said that the animals have habitual patterns of behavior as habit behavior. In the listening material, the professor gives two examples to illustrate such patterns in detail. First example is about a kind of small fish. The male fish can do attack dance to the fish with red marks that enters its territory, but won’t do the dance to the fish without red marks. The second example is goose. The female goose will move its head back and forth after it lays eggs, but when its eggs are moved away, it will still do such behavior. These two animal behavior are both cases of habitual patterns.
