But the impression is fleeting, and serves only to give a greater acuteness to the enjoyment of the moment.

但这种印象并没有长久留在你的脑中，这只能使你更加敏锐地感到当前生活的欢乐。

Now that I look back I am more than ever impressed by Stroeve's acuteness.

在回想来，施略夫当时真称具慧眼了。

Sight and scent became remarkably keen, while his hearing developed such acuteness that in his sleep he heard the faintest sound and knew whether it heralded peace or peril.

他变十分敏感的视觉和嗅觉, 他的听觉也飞速进步: 睡梦中听到极其细微的一点声响, 他便可以判断知这声响预示着是平安还是凶险。

Moreover, after looking at him one would have hazarded the guess that good nature, and an acuteness as extreme as it could be without verging on craft, formed the framework of his character.

见过他的人还可能会揣度，他是个心地纯真，思维敏锐，但不至于奸诈的人。
