The document provides information about the functions of various parts of a car, distillation apparatus, and human body. It contains pictures and tables labeling parts and describing their functions. Students are asked to look at the pictures and complete sentences by matching parts to their functions. For example, they write that the radiator cools the engine, the brake stops the car, and the eyes enable us to see. The document aims to teach students about the relationships between structures and functions.
