介词加关系代词是什么？
介词加关系代词有以下用法：
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)
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.
物理是我们学校每个学生都很感兴趣的课程。（注意搭配be interested in)
3、根据与先行词的搭配来确定介词。如：
This is our classroom, in the front of which there is a teacher’s desk.
这是我们的教室，前面有老师的讲台。（注意搭配in the front of our classroom)
4、根据句意来确定介词的使用。如：

这就是那本书，从中我读到这个故事。（由于句意含有“从……”的意思，所以用介词from)
介词加关系代词的搭配注意事项
介词放在句末时，who，that，which可省，但介词在关系代词前时，只能用“介词＋which/whom”结构。含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。
介词加关系代词怎么用？
“介词＋关系代词”在从句中主要起关系副词的作用，即在定语从句中充当状语。
表示地点，时间和原因的“介词＋which”分别相当于where，when，why。I have found the book in which thenames of all the early satellites are mentioned．（SEFC 2A L．55）（＝Ihave found the book．The names of all the early satellites arementioned in it．）The earth on which ／where we live is aplanet．
way后常用that代替in which，也可省略that。I really don't like the way that hetalks．That was the way in which the old ladylooked after us．Do it the way I showed you．
“of＋which”起形容词的作用，相当于whose（用来指物），其词序通常是“n．＋of which”。They live in a house whose door ／thedoor of which opens to the south.He's written a book whose name ／thename of which I've com- pletely forgotten．

介词+关系代词是什么？
介词＋关系代词在这种结构中，关系代词若是表示人的意义，就只能用whom；关系代词若是表示事物的意义，就只能用which。
而这种结构中较难解决的问题是介词的选择问题，因为这个问题的解决取决于多种因素：
动词与介词的搭配B）名词与介词的搭配C）形容词与介词的搭配，等等。总之，要依从句的具体需要而定。
例如：
动词与介词的搭配。
He has found a good job for which he is qualified .（qualify +名词＋for "使…具有…资格＂）他找到了一份他能胜任的工作。
名词与介词的搭配
They are still living in the little house in which they've been lived for 15 years .（in the house "在屋子里＂）他们现在还住在他们已住了15年的那个小房子里。
介词加关系代词的三种情况是什么？
1、介词是跟动词搭配，动词往往不及物，或动词短语带有介词。这种情况一定要注意短语动词 look for，run into 之类的，整个视为一个单词，在句中不能拆开使用。
This is a problem most of us are likely to run into。
这是我们大多数人都可能遇到的问题。
2、介词跟形容词搭配使用。
Every student should do the assigned tasks for which they are responsible independently。(be responsible for)
每个学生都应该独立完成分配给他们的任务。(负责)
3、介词跟在名词后面
He had a wonderful chilhood，about which he wrote many stories。(stories about )
他有一个奇妙的童年，为此他写了许多故事。(关于的故事)
4、状语是一个介词短语
The professor wrote for him a letter of recommendation with which he applied for a position in that company。
教授为他写了一封推荐信，他随信申请了那家公司的一个职位。
