Although the relationship between understanding the contents and grasping the view is bi-directionally, it is worth trying to grasp the view of a given research first, then understand the remains. This strategy is easier, particularly for me. Never forget to look for the author's viewpoint. Ask myself: "What's the view of the research?" Now I must be able to find the goal of the research easily.
