    - 根据从句中谓语和介词的搭配，并且要判断“动词 + 介词”与先行词的逻辑关系
      - The girl for whom he had fought 2 years seems no longer important to him.（fight for sb（为……而斗争），所以用for whom，在从句中做宾语）
      - I have bought many things on which I spent most of my money that I saved.（spend money/time/energy on sth（在……花费金钱/时间/精力），在从句中做宾语）
    - 根据从句中动词和先行词的逻辑关系

      - The colorless gas without which we can't live is called oxygen.（根据逻辑判断，应该加入without）
      - This is the classroom in the front of which there is a desk.（根据逻辑判断，教室前面有讲台，所以加入介词短语in the front of）
