对于“介词+关系代词”结构的使用，重点是要弄清其中的介词如何确定和判断。归纳起来，有以下几点方法： 1. 根据与定语从句中动词的搭配来确定介词。 如： Water is the natural medium in which fish live. 水是鱼类赖以生存的自然环境。(注意搭配live in) The documents for which they were searching have been recovered. 他们找寻的文件已经找到了。(注意搭配search for) This is a subject about which we might argue for a long while. 这是一个我们可能长时间争论的问题。(注意搭配argue about) 注意，对于那些由动词与介词构成的短语动词，通常不宜将它们拆开使用，此时应注意介词的位置应。如： The boy (whom) my sister is looking after is getting better. 不能说成：The boy after whom my sister is looking is getting better. 2. 根据与定语从句中形容词的搭配来确定介词。 如： Physics is the subject in our school in which every student is interested. 历史是我们学校每个学生都很感兴趣的课程。(注意搭配be interested in) He referred me to some reference books with which I am not very familiar. 他我要去参考一些我不熟悉的参考书。(注意搭配be familiar with) |
