Animal training refers to teaching animals specific responses to specific conditions or stimuli (刺激). Training may be for the purpose of companionship, detection, protection, entertainment or all of the above. An animal trainer may use various forms of reinforcement (强化) or punishment to condition an animal’s responses. Some animal trainers may have a knowledge of the principles of behavior analysis and operant conditioning (操作性条件反射), but there are many ways to train animals and as a general rule no legal requirements or certifications are required.   Training ch填词语。 机________可失　　寸步________离　　万无________失
