In fact, the analysis of inference questions should first analyze the problem, to clarify the problem; Second, through the analysis to be able to seize the key words or lexicons implicit in the title, accurately understand the problem, which is the breakthrough; Third, good at based on the characteristics Phenomenon of association, from the phenomenon of thinking of the characteristics of their own substances, and then infer, come to a conclusion.
