“介词+关系代词”引导的定语从句
在定语从句中，当关系代词作动词短语或介词的宾语时，为了使关系代词与先行词的关系更加密切，通常用“介词+关系代词”引导定语从句。
1. 若介词放在关系代词前，关系代词指物时只能用which，关系代词指人时只能用whm。 eg The man by whm the thief was caught was a gd pliceman. This is the reasn fr which I was praised by my chemistry teacher.
2. “介词+关系代词”引导的定语从句中关系代词不能省略，但介词后置时，限制性定语从句中的关系代词可以省略。
3. “介词+关系代词”中的介词根据从句中谓语动词的搭配习惯、先行词与介词的搭配习惯或句子要表达的意思来选用。 eg He is the persn frm whm I learn a lt. (learn frm) Testing is still the usual means by which students’ prgress is measured. (be measured by) Air, withut which man can’t live, is really imprtant. 
4. 当定语从句中的谓语动词是带介词的短语动词时，短语动词中的介词一般不能前置。判断正误The baby whm the nurse is lking after is very healthy. The baby after whm the nurse is lking is very healthy.
引导定语从句的“介词+ which”有时也可以用关系副词来代替。eg Beijing is the city, in which (= where) he has lived many years. I remember the day n which (= when) I went abrad. The reasn fr which (= why) he didn’t cme isn’t clear. 
“介词+ which / whm”前还可加sme, any, nne, all, bth, neither, many, mst, each, few 等。eg She has tw sns, bth f whm are dctrs.  There are many kinds f birds in this cuntry, many f which are endangered.
