When I have fears每当我害怕 by 济慈 英语带中文翻译：
When I have fears that I may cease to be
每当我害怕，生命也许等不及
Before my pen has glean'd my teeming brain,
我的笔搜集完我蓬勃的思潮，
Before high-piled books, in charactery,
等不及高高一堆书，在文字里，
Hold like rich garners the full ripen'd grain;
象丰富的谷仓，把熟谷子收好；
When I behold, upon the night's starr'd face,
每当我在繁星的夜幕上看见
Huge cloudy symbols of a high romance,
传奇故事的巨大的云雾征象，
And think that I may never live to trace
而且想，我或许活不到那一天，
Their shadows, with the magic hand of chance;
以偶然的神笔描出它的幻相；
And when I feel, fair creature of an hour,
每当我感觉，呵，瞬息的美人！
That I shall never look upon thee more,
我也许永远都不会再看到你，
Never have relish in the faery power
不会再陶醉于无忧的爱情
Of unreflecting love;--then on the shore
和它的魅力！——于是，在这广大的
Of the wide world I stand alone, and think
世界的岸沿，我独自站定、沉思，
Till love and fame to nothingness do sink.
直到爱情、声名，都没入虚无里。
