An Inconvenient Truth

At the beginning of the narration, there is a short description of the beautiful environment. In order to let the audience have a better feeling, a lot of strong words are used to describe the river, leaves, birds and so on. There strong words make these things more vivid and we can even imagine the picturesque view. 

    The first persuasion strategy that Al Gore uses is using humorous and sardonic expression which gives us a deep impression and easy way to understanding. For instance, in order to explain global warming, he uses a humorous cartoon to make us understand global warming more easily. Meanwhile, he takes his classmate as an example to interpret some important principle. This sardonic way can make the principle not be boring and people can accept this way easily.

    The second strategy that he uses is persuading people by using comparison. In his speech, he wants to tell people the importance of solving the global warming problem. Therefore, he needs to show the damage of global warming. In order to express the damage of global warming, he shows a lot of pictures of the same glacier, taking in different periods. According to the comparison, people can greatly feel the importance of solving this problem. If not, the whole planet will be submerged by the water from the large amount of glaciers. Eventually, the humans are the victims.
