今天看到经济学家科斯论文里的两句话:This paper is concerned with those actions of business firms which have harmful effects on others. The standard example is that of a factory the smoke from which has harmful effects on those occupying neighboring properties. 后面一句我实在读不明白。
1.The standard example is that of a factory 这个that指的什么?
2.这里The standard example is that of a factory the smoke from which...factory 后面直接跟了the smoke,这是中间省略了什么吗?
按我对句意的理解,that 值得就是the smoke,可是这里为什么the smoke又能直接接在factory后面?
希望各位赐教!
