Book 3 Unit 1 ,The world of our senses,Whats that smell？Do you hear that noise？Taste this！Look at me！Feel this，isnt it soft？When you hear，or even use these phrases，you probably dont stop to think about why we use them.Well，its because of our sense.Without us even knowing，our sense organs (nose，eyes，ears，tongue，and skin) are taking in information and sending it to the brain for processing.If we didnt have them，we would not be able to smell，see，hear，taste，or touch anything!,话题语篇导读,Senses are the physical means by which all living things see，hear，smell，taste，and touch.Each sense collects information about the world and detects changes within the body.Both people and animals get all of their knowledge from their senses，and that is why senses are so important. All senses depend on the working nerve system.Our sense organs start to work when something stimulates special nerve cells，called receptors，in a sense organ.Once stimulated，the receptors send nerve impulses along sensory nerves to the brain.Your brain then tells you what,to do.For example，your sound receptors are often attacked by billions of sound waves.When these signals reach the part of the brain called the cerebral cortex，we become conscious of the sounds.
