Actually, the brain is confused and not the eyes.Step 4: Discussion Read the three questions in the short passage and discuss them in groups of four. Report your answers to the whole class. We often use one or two of the five senses more than the others when we need to . For example,in the darkness, the sense of haering and the sense of touch bee more sensetive bacause we cannot see anything, when we listen to our favourite music, we may close our eyes and just listen with our ears.when we eat something, we not only taste or smell it, but look at it as well. I think that when learing english, the sense of sight and the sense of hearing help me a lot. I usually listen to the tape before I read. While Im listening to the tape, Ill look at the text. And I often read iit aloud. The bination of the senses best helps me remember what I have learned.Step 5 Consolidation Review the five senses once again and finish the exercises given on show, which, of course are related to the senses.When he got there, he _ that there was a dark hole.
