Conduct may be founded on the hard rock or the wet marshes, but after a certain point I don’t care what it’s founded on.
When I came back from the East last autumn I felt that I wanted the world to be in uniform and at a sort of moral attention forever;
I wanted no more riotous excursions with privileged glimpses into the human heart.
Only Gatsby, the man who gives his name to this book, was exempt from my reaction—Gatsby, who represented everything for which I have an unaffected scorn.
riotous excursions 【riotous：纵情欢闹的；excursion：短途旅行。】
If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life, as if he were related to one of those intricate machines that register earthquakes ten thousand miles away.
This responsiveness had nothing to do with that flabby impressionability which is dignified under the name of the “creative temperament.”—it was an extraordinary gift for hope, a romantic readiness such as I have never found in any other person and which it is not likely I shall ever find again.
gestures：姿态。gorgeous：绚丽的。promises:（非常好的或成功的）希望，迹象，指望。register :记录. flabby impressionability:软弱的敏感。dignified:美化。creative temperament:创造性气质。
No—Gatsby turned out all right at the end;it is what preyed on Gatsby, what foul dust floated in the wake of his dreams that temporarily closed out my interest in the abortive sorrows and short-winded elations of men.
preyed on ：make sb worry continuously。
abortive sorrows ：短暂的悲伤。abortive:失败的，夭折的。
【尼克虽然对盖茨比 是“unaffected scorn”，但总体来看，盖茨比还是无可厚非的。是那些吞噬盖茨比心灵的东西，那些在他幻梦消散后浮现出的污浊尘垢，让我对人们短暂的悲伤与一时的得意暂时失去了兴趣。】
