It never rains but it pours.一定要英文解释,不少于十句!用英文解释It never rains but it pours,不少于十句，明白？

真的很难凑十句，原意是“不下则已，下则倾盆”，翻译成中文含意当然就是“不鸣则易，一鸣惊人”喽！赶巧上个礼拜老师刚讲，绝对正确，相信我！
另附以文章（就算十句吧）IT NEVER RAINS BUT IT POURS - "One stroke of good (or ill) fortune is often followed by many other instances of luck (or misfortune) when you least expect them. The proverb dates back to the eighteenth century. In 1726, English physician John Arbuthnot (1667-1735), published a book entitled 'It Cannot Rain But It Pours.' Jonathan Swift (1667-1745) and Alexander Pope (1688-1744) collaborated on an essay entitled 'It Cannot Rain But It Pours.' The saying has been use ever since." From "Random House Dictionary of Popular Proverbs and Sayings" by Gregory Y. Titelman (Random House, New York, 1996). The saying, in a slightly different form, is the slogan for Morton Salt: ".The company developed a salt that would be free-running even in damp weather. In 1911, a little girl with an umbrella and her now-famous slogan, 'When It Rains It Pours,' were created to promote this new product in a national consumer advertising campaign. The Morton Umbrella Girl and slogan first appeared on the blue package of table salt in 1914. Throughout the years the ageless girl has changed dresses and hairstyles to stay fashionable. She was updated in 1921, 1933, 1941, 1956 and 1968. Together they have symbolized the growth and progress of the company through the years."
it...but...就是不怎么怎么样，一怎么怎么样就很厉害的意思，是固定搭配，别听前边人下掰

It never rains but it pours.= 本来从不下雨的,却下起了倾盆大雨.
也就是“祸不单行”的意思.
不知道你要十句的是什么
