“介詞+關(guān)系代詞”引導(dǎo)的定語從句
在定語從句中，當(dāng)關(guān)系代詞作動(dòng)詞短語或介詞的賓語時(shí)，為了使關(guān)系代詞與先行詞的關(guān)系更加密切，通常用“介詞+關(guān)系代詞”引導(dǎo)定語從句。
1.?若介詞放在關(guān)系代詞前，關(guān)系代詞指物時(shí)只能用which，關(guān)系代詞指人時(shí)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.?“介詞+關(guān)系代詞”引導(dǎo)的定語從句中關(guān)系代詞不能省略，但介詞后置時(shí)，限制性定語從句中的關(guān)系代詞可以省略。
3. “介詞+關(guān)系代詞”中的介詞根據(jù)從句中謂語動(dòng)詞的搭配習(xí)慣、先行詞與介詞的搭配習(xí)慣或句子要表達(dá)的意思來選用。 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. 當(dāng)定語從句中的謂語動(dòng)詞是帶介詞的短語動(dòng)詞時(shí)，短語動(dòng)詞中的介詞一般不能前置。判斷正誤The baby whm the nurse is lking after is very healthy. The baby after whm the nurse is lking is very healthy.
引導(dǎo)定語從句的“介詞+ which”有時(shí)也可以用關(guān)系副詞來代替。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.?
“介詞+ which / whm”前還可加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.?
