查询词典 cast a damp over

During my subsequent movements in different parts of the country, and a tarriance of three busy weeks in London, I had no leisure for replying to it; and now that I am once more at home, and am clearing off the arrears of business which had accumulated during a long absence, it has lain unanswered till the last of a numerous file, not from disrespect of indifference to its contents, but because, in truth, it is not an easy task to answer it, nor a pleasant one to cast a damp over the high spirits and the generous desires of youth.

接着，我巡游全国各地，又在伦敦忙了三个星期，因此耽误了，没有时间给你回信。现在回到家中，要料理完这段时间搁置的事情，因此，我只有把成堆的文件处理完毕，才能回复你的来信，不是因为我轻视信中所言，也不是故作冷淡，而是因为回复这封信可不是件容易的事，同时，泼一盆冷水在兴致盎然、胸怀大志的年轻人头上也非悦事。
