adapter

I also remember clearly when we were in school, the teacher told us about the adapter in detail, and now it is very useful in our life, the last time we clean up at home saw the adapter at home, I think about the adapter we learned before, really is With the help of the computer, I will remember that now in our family, I also often remind our children to review more of the knowledge they have learned, it is really important. In the usual work and study can also use a lot of knowledge, learning is still early, there is still life to learn, adapter is a good thing.
