牛津大學(xué)客座教授：概念界定從句中的關(guān)系代詞3

3. If possible use when and where in definitions only if necessary. These may seem overly informal to readers. 如果可能，僅在必要時在概念界定中使用 when 和 where。 這些對讀者來說似乎過于非正式

例如： Pollution is when the environment becomes contaminated as a result of human activity. 污染是指環(huán)境因人類活動而受到污染.

修改為：Pollution is a form of environmental contamination resulting from human activity. 污染是人類活動造成的環(huán)境污染的一種形式。

A fault is where there is a fracture in the earth’s crust and the rock on one side of the fracture moves in relation to the rock on the other side. 斷層是地殼中存在裂縫并且裂縫一側(cè)的巖石相對于另一側(cè)的巖石移動的地方。

修改為： A fault is a fracture in the Earth’s crust in which the rock on one side of the fracture moves in relation to the rock on the other side. 斷層是地殼中的裂縫，其中裂縫一側(cè)的巖石相對于另一側(cè)的巖石移動。
