does Mike go to read in the city library?

    Do you really care about your parents? Hearing this question, most people may give a quick answer "Of course, I do." But maybe you don't.

    It is true that all parents can remember clearly when to  their children's birthdays. However, it is a  that few children know exactly when their parents' birthdays are. Most parents can  name the food their children favor. The other way round, some students don't know  their parents like most of all.  

    Sometimes we can hear parents complain that their children don't talk with them as often as before. Children are growing and the generation gap(代沟)is widening.
