An owl(猫头鹰) is a bird. There are two basic types of owls: typical owls and barn owls. Owls live in almost every country of the world.
Owls are mostly nocturnal, meaning they are awake at night. Owls are predators——they hunt the food that they eat. Owls hunt for mice and other small mammals, insects, and even fish. Owls are well adapted for hunting. Their soft feathers make their flight nearly silent. They have very good hearing, which helps them to hunt well in the darkness. The sharp hooked beaks and claws of the owl make it very easy to tear apart prey quickly, although owls also eat some prey whole.
Owl eyes are unusual. Like most predators, both of the owl's eyes face front. The owl cannot move its eyes. Owls are far-sighted, which means they can see very well far away, but they can't see up close very well at all. Fortunately, their distant vision is what they use for hunting, and they can see far away even in low light.
Owl can turn their heads 180 degrees. This makes it look like they might be able to turn their heads all the way around, but 180 degrees is all the owl needs to see what's going on all around him.
(66) Perhaps because of the owl's mysterious appearance, especially its round eyes and flexible neck, there are a lot of myths and superstitions (迷信) about owls. Many cultures believe that owls are unusually wise. Because owls are nocturnal, some cultures associate owls with bad omens. However, owls probably do not interact with the fates of humans at all. In fact, some owl species may become extinct because of humans.
Which of the following is NOT true about owls？
A．Owls eat small animals.
B．Owls are able to fly silently.
C．Owls have very poor vision.
D．Owls have flexible necks.
For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts lead to “rewards”; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological (生理的)“drives” as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.
Papousek began his studies by using milk in the normal way to“reward” the babies and so taught them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement“switched on” a display of lights-and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would“smile and bubble” when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.
According to the author, babies learn to do things which______.
A．are directly related to pleasure
B．will meet their physical needs
C．will bring them a feeling of success
D．will satisfy their curiosity
