核心句型：
A friend in need is a friend indeed.
患难见真情。
A friend in need is a friend indeed.这则谚语源自古罗马诗人、剧作家昆塔斯·恩尼乌斯的作品，直译成汉语即：“在最需要帮助的时候帮助你的人才是真正的朋友”，也就是说：“患难见真情”。因此，当美国人说"A friend in need is a friend indeed."时，他/她要表达的意思就是:"A friend who can give a hand when you're in trouble is a true friend."、"Misfortune tests the sincerity of friends."。
