介绍是否应该帮助陌生人

　　Helping strangers has always been considered as a treasured virtue of human kind .We need help from others throughout our life, whenever we travel to other places or stay at home .On the other hand, helping others can make us happy .We feel great joy when we are trusted, needed and able to give a hand.

　　However ,some people are cautious when it comes to helping strangers .They say that helping others involves risks of getting hurt or cheated .Lending a hand to a stranger often puts us in a vulnerable position for it means trusting a hand to a stranger often puts us in a vulnerable position for it means trusting someone we do not even know .Moreover ,there are times when we have physical limitations- e.g. we can t swim but a girl is drowning .If we are blind to that limitation ,giving a hand would conversely take our life.

　　In my opinion, we should still offer what we can do to help needed strangers. Meanwhile, we should beware of getting cheated and use common sense to tell whether the strangers are real needed people or just professional cheats .Detecting anything unusual, we should defend ourselves or turn to the police.
