The analysis of three metafunctions of image

 

         When we take a first look at the image,obviously,we would be attracted by a boy who setting  off the ocean while finding two  empty bottles.The image is used to represent our experience that 

 there is a large amount of rubbish throwing into the ocean.At the same time,it brings the viewers a deep impression because in our commen sense the oceans is clean and blue but the reality is that many artificial things were abandoned into it.The image shows the very interesting contrast between the ocean we imagine and the ocean in fact.

         In terms of imformations value,it accented the importance of preventing people from casually throwing rubbish if we pefer to the blue ocean.What's more,it indirectly criticizes this kind of  phenomens and makes people spontaneously constraint their behaviours.
