Unit 1 The world of our sense  Welcome to the unit---教案

why are  people mislead by their own eyes?
because the background or other lines confuse the eyes.
also ,what we expect to see can change what we see. 
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 become 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 i’m listening to the tape, i’ll look at the text. and i often read iit aloud. the combination 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.
