The body of an animal may compare to some machine such as a locomotive. In fact, the body of an animal itself is a machine, which is composed of many parts. Each part plays a special role, with special structure supporting it. All of the parts rely on and cooperate with each other, in order to fulfill the operation of the machine. A locomotive has to be added fuel, such as coal, firewood, or other flammable substance, consuming which may provide motion or energy for the machine. The body of an animal also need fuel supplementation being called food, which may provide energy to the animal. In order to ignite the flammable substance and oxidize the food in the animal body, oxygen is essential. The locomotive is composed of special parts: the hearth to accept and ignite the flammable substance, the pipe to transport steam, the wheel to make the locomotive move on, and the chimney to exhaust gas. While the animal body is also composed of different parts: gastrointestinal tract to ingest and absorb food, the emunctory organ to evacuate waste, the arteries and veins to transport oxygen and store nutriment, and the legs and wings to move on.
听写作业：Animal and machine
The body of an animal may well to compare with some machine like a locomotive engine. Indeed, the animal body is a machine. It is a machine composed of many parts, each part doing some particular of work for which particular work kind of structure fits it. And all the parts are dependent on each other and works together for the accomplishment for the total business of the machine. The locomotive must be provided with fuel such as coal or wood or other combustible substance. The consumption of which furnish the force and energy of the machine. The animal body must be provided with fuel which was called food which furnish similarly the energy of the animal. Oxygen must be provided for the combustion of the fuel in the locomotive and the food in the body. The locomotive is composed of special parts: the fire box for the reception and combustion of the fuel, the steampipes for the carriage of the steam, the wheel for the locomotion, the smoke stack for throwing of waste. The animal body is similarly composed of parts: the alimentary cannel for the reception and similation of food, excretory organs for the throwing of the waste matter, the arteries and veins for the carriage of oxygen and food holding blood, the legs or wings for the locomotion
