finished exercises:L7-15

  Remember words with LP5800.After finishing the strange words remembering of high school,I will remember ST words formally.

  Doing exercise of NCE 2 is a bit difficult to me,I planed finishing it within 3 months company with reading and remembering words.

  In order to realize my goal,I should be in a long fighting,the goal should be reached by bit add bit,so,despite the boredom feeling bothering me sometimes,I will learn something every day without interspace.Only in this way,can I achieve the aim.
