As a teenager, waiting for the hectograph to “freshen” between pages printed (while “freshening, ” the print would melt into a vague purple membrane which hung in the jelly like a manatee's shadow) drove David all but insane with impatience.

等他长成个十几岁的愣头小子，呆在一旁等着胶版誊写机“复原”之后才能再印下面一页（未“复原”时印出来的字会溶成紫不拉叽的一团，粘在胶版上，就像海牛的影子），戴维不耐烦得简直要发疯。
