(众所周知，朋友在我们的学习、工作和日常生活中扮演着重要的角色)As friends we should help and trust each other and share not only joys but sorrows as well. To keep our friendship, we shouldn't only think of ourselves.   (想想我们为朋友做过什么而不是他们为我们做了什么). Once our friends are in trouble, we should try our best to help them out. Just as the famous saying goes: (患难见真情). Besides, as friends we should be honest to each other, and never tell lies. Otherwise, our friendship will end soon.

As it is with everything else, (友谊也需要被好好照顾). Once we become friends with someone, we should help, value, and respect each other. (只有这样我们的友谊才会持久). With friends around us, we are sure to enjoy a happier life.
