解释：使用毒性大的药物治疗疾病时，病情十成中只能去掉六成就要停药，以免伤害正气。

The time which we have at our disposal every day is elastic; the passions that we feel expand it, those that we inspire contract it; and habit fills up what remains.

Most people are other people. Their thoughts are someone else’s opinions, their lives a mimicry, their passions a quotation.

The past does not equal the future.

诗歌的美在于它能够超越时间和空间。
