| Time flies so quickly! We become mature (成熟的) girls or boys, or at least we 1 we are. At the same time, our parents are no longer young. They 2 all they have to us but never look forward to getting 3 back. When we are all in bed, they stay with us day and night. When we're hungry or cold or sad, they 4 offer help. But what have we done for our parents? 5 we grow up, we have our own ideas and we believe we are 6 enough to think and act by ourselves, so we usually dislike their care. 7 , we don't listen to them; sometimes even quarrel with them! We must 8 something now, letting them know that we love them, too. Try our best to understand our parents, and not to make them feel hopeless. In a word, make it a duty to bring 9 to them because that's the sign that we are really mature. Children are parents' 10 and we are carrying both our dreams and theirs. The pleasure of our parents is what we should try to do! | ||||
