The passage says that the sensory receptor is the structure that detect changes in an animal's external and internal environment. Passage also says that some sensory receptors are stimulated by physical bending or stretching caused by forms of mechanical energy such as pressure, touch, and motion.
The lecturer says that cat's whiskers are the most common example of sensory receptors. It says that cat's whiskers are long and highly sensory hair. It's twices thick, and three times deeper than other hairs. It can detected very soft movement like air condition changes. In the dim light, cats can't see the light. It just sences air condition in the dark and it helped cat improve ability to work in dark

Sung-Ho,
First of all nice job introducing the reading passage and by giving a brief definition of what a sensory receptor is. This is a great way to start any question four response.
Below are some word choice and grammar corrections:

The lecturer says that cat's whiskers are one common example of sensory receptors. He says that a cat's whiskers are long and highly sensitive hairs. These whiskers are twice as thick as, and three times deeper than other hairs. A whisker can detect very soft movement such as subtle changes in air conditions. In the dim light, cats can't see well. Instead, they just use their whiskers to sense objects in the dark. This improves the cat's ability to maneuver in dark.
