Today, I learned two things about PC and smartphones. First, I learned the functions of “Microsoft Excel” which is used for writing like “Microsoft Word.” I have already known this filed as role for making figures since when I was junior high school student. After entering high school, I learned that “Excel” is the tool of making sentences in the information class. My father so surprised at the unbelievable fact and I embarrassed myself. Updating my old one of the stereotypes, I am going to try to use “Excel” when I must write reports. Second, I also learned that the plan of smartphones. When I was talking with my family about whether to replace broken smartphones, I knew “the anytime exchanging program.” This is the program that the users can change their mobile phone until they pay the monthly fee. Moreover, they can exchange their smartphones to new type one starting twenty third months later. In other words, you can continue to use the brand-new phones in every releasing time by using this subscription. However, I think that it is better to continue to use the first replacing phones than repeating this system. That’s because it is cheaper than repeating Payments of the fee. How about you? Please give your opinions!
