Read the following passage carefully until you have got its main idea, and then select one appropriate word for each gap from the box following the passage.Behavior is the way that animals act. For example, how do they get food or take care of their young? How do they find a place to live in or [protect] (1) themselves from danger? Much behavior is innate; that is, animals are born with it. [However] (2), animals learn much other behavior. There are several kinds of learned behavior.One simple [type] (3) of learned behavior is habituation. Thishappens when an animal learns to feel comfortable in a new [situation] (4) and doesn't pay attention to it anymore. For example, young horses are often afraid of noisy streets.

It is a way of learning by association —that is, by putting [together] (6) different ideas. In 1900, Ivan Pavlov, a Russian biologist, studied conditioning in dogs. Dogs innately salivate (produce liquid in the mouth) when they smell food. Pavlov [rang] (7) a bell every time he gave food to a dog.
