for结构的介词短语在句中作方面状语还是定语判断
介词短语既可以作定语，也可以作状语，所以仅从语法上是无法判断for介词短语是定语还是状语，只能根据逻辑做出判断。在污染物水平这一点上，洛杉矶市美国最差的城市。我们可以用as far as levels of pollutants are concerned.来替换for介词短语，句义基本不变。可见for介词短语是修饰句子的状语，而不是修饰city的定语。

Keep contact with与keep in contact with中keep是系动词么？
Keep contact with中，keep为及物动词，后接宾语+状语。keep in contact with中，keep是系动词，介词短语作表语。比较 be in contact with。主语句子的逻辑，如果用系词be替换动词，句子逻辑仍然成立，被替换的就是系词。否则就不是系词。我们可以说He is in contact with sb. 但你能说 He is contact with sb吗？
