It is a common experience in our daily life that disagreement often exist,because of different levels of education or  different  living environment.in my opinion ,disagreement can help us learn more .it indeed brings press and discomfortable,however which in turns promote us to find our shortness and make us a better one.      shared opinions is somewhat to consolidate what we have learned or knew,which is a repeat of our thinking pattern.however,different opinions give our an opportunity to rethink ourselves and provide us another prespect to look into the certain topic,through which we may find our shortness.a good example is that  a  cook usually regard delicious a chief element making dishes,while parents think nutrition play a more important in our meals.it is hard for cook to persuade parents ,thing is the same  to parents .however after the exchange of opinions ,they may take the other factor into account when making meals next time for they can look things in another way and broaden thinking mode. we can eat deintys containing necessary nutritions in restaurant as well as having a vatamin-abundant and delicious lunch at home.we can see disagreement is not a bad thing,what we can get is a more perfect one rather than  stressed feelings.      however when the opinions is shared,we are indeed encouraged and lighten by the cogizationg from others and become confident,which will motivate us to some extent to further our study and explore more.     in sum ,disagreement is dramatically marked as a opportunity to improve ourselves.we can learn more from it.
