介詞+關系代詞思考：什么情況下考慮用介詞+關系代詞？如何選擇介詞？介詞后可以使用那些關系詞？ImportantpointsA.Theperson(who/whom/that)youshouldwritetoisMr.Ball.B.ThepersontowhomyoushouldwriteisMr.Ball.2.A.Thegames(which/that)hecompetedinwereswimmingandshooting.B.ThegamesinwhichhecompetedwereswimmingandshootingWhatarethedifferences?B.Forexample,itisthecountryinwhichsilkwasfirstinvented.3.A.Forexample,itisthecountry（which/that)silkwasfirstinventedin.4.A.Heisaman(who/whom)Chinacanbeproudof.B.HeisamanofwhomChinacanbeproud.

Conclusion當從句不缺主語或賓語時，可考慮用介詞＋關系代詞。當確定用介詞＋關系代詞時，介詞的選用可考慮介詞與從句中動詞、形容詞的搭配或與先行詞的搭配。3.當介詞放在關系代詞前時，介詞賓語只能用which和whom。如先行詞是物，引導詞用which，先行詞是人，引導用whom。不可用that或who代替1)看定語從句中動詞與介詞的搭配Thisisthebookwhichyouaskedfor.Thisisthebookforwhichyouasked.(askfor)

注意：有些“動詞+介詞”短語，如lookfor,lookafter等不可拆開，不能把介詞置于關系代詞之前如：TheoldmanwhomIamlookingafterisbetter.如何選擇介詞2)看定語從句中形容詞與介詞的搭配

HereferredmetosomereferencebookswhichIamnotveryfamiliarwith.

HereferredmetosomereferencebookswithwhichIamnotveryfamiliar.(befamiliarwith)3)根據(jù)先行詞判斷,所用的介詞與先行詞搭配

Inhisroom,wesawabigtablewhichthereallkindsbookson.Inhisroom,wesawabigtableonwhichthereallkindsbooks.
