解答：

幫助陌生人一直被視為人類珍貴的美德.在我們的生活中,我們旅行到其他地方,或呆在家里,都會需要別人的幫助.另一方面,幫助別人可以使我們很快樂,我們會感到極大的滿足,當我們被信任可以幫忙并伸出援手.然而,有些人很謹慎,當談到幫助陌生人,他們擔心有風險或者受到傷害或者欺騙,這往往使我們處在一個脆弱的位置,因為這意味著我們要信任一個我們甚至不認識的人,此外,經常是在我們身體條件受到限制的情況下,比如我們不會游泳,但是有個女孩在水中溺水.如果我們被自身條件限制而去伸出援手,我們將會失去生命.在我看來,我們還是應該做些力能及的事情來幫助那些需要幫助的陌生人.同時,我們應該意識到受騙和使用常識來判斷陌生人是真正需要的人或者是騙子.檢測任何不尋常的,我們應該維護自己或找警察
