填空题 But let no one think that pleasure is immoral. Pleasure in itself is a great good, all pleasure, but its consequences may be such that the sensible person eschews certain varieties of it. Nor need pleasure be gross and sensual. They are wise in their generation who have discovered that intellectual pleasure is the most satisfying and the most enduring. It is well to acquire the habit of reading. There are few sports in which you can engage to your own satisfaction after you have passed the prime of life: there are no games except patience, chess problems and crossword puzzles that you can play without someone to play them with you. Reading suffers from no such disadvantages: there is no occupation—except perhaps needle-work, but that leaves the restless spirit at liberty—which you can more easily take up at any moment, for any period, and more easily put aside when other calls press upon you: there is no other amusement that can be obtained in these happy days of public libraries and cheap editions at so small a cost. To acquire the habit of reading is to construct for yourself a refuge from almost all the miseries of life.
