核心问题
M. Swan 在 Practical English Usage(§ 273)中说：
“表达健康以外的意思时, well 不能用作形容词。”(《牛津英语用法指南》, 外研社, p.290)
由此看来,下句中的 well 也只能作“健康”解了:
-
I hope you are very well.
-
All is well with us.
词典解答
M. Swan 的说法不够全面。实际上，用作形容词的 well，除了作“健康的”解之外，还可作“顺利的”“好的”“令人满意的”解：
-
All is well with the family. 全家一切都好。
-
All's well that ends well. 结局好一切都好。
-
It would be well to start early. 最好早点儿动身。
-
It's all very well for you to criticize, but could you have done any better yourself? 你提出批评当然很好，但你自己干难道会做得比这更好吗？
