定語從句引導詞前面的介詞一個用什麼
Later they may give performances in pubs or clubs，for which they are paid in cash .這裡為什麼for .They may start as a group of high-school students，for whom practicing their music in someone’s house is the first step to fame.這句也是

第一句是paid（pay）.for固定短語
第二句for whom對於他們來說

定語從句中的介詞提前，介詞+whose引導的定語從句的用法
關係代詞whom和which在從句中作介詞的賓語時，與介詞放一起只用whom和which，那介詞+whose怎麼用？

以下是你要的句子：第一步This isMr.Smith.Wework in his company（把這兩句合併起來）：第二部This isMr.Smith，IN WHOSE factory we work.又如We are visitingMr.Wang.Peopletalk a lot aboutMr.Wang's f…

定語從句中何時能用介詞+which代替when，where，whose，why？
看看下列句子用括弧內的詞能否成立？
1.The brige where（in which）this photo was taken has been rebuit.
2.What is the address of the firm whose（of which）advertisement we noticed the other day？
3.The reason why（for which）they now charge more is that prices have kept rising.
4.It was raining on the day when（on which）taey arrived.
5.Living in a house whose（of which）walls are made of glass would be horrible.
6.There weren't any movie theaters in the town where（in which）I spent my last summer.

1.The brige where（on which）this photo was taken has been rebuit.
2.What is the address of the firm whose（of which the）advertisement we noticed the other day？
3.The reason why（for which不可換reason作先行詞時後常用why引導從句當然只有reason在從句中做狀語時）they now charge more is that prices have kept rising.
4.It was raining on the day when（on which）taey arrived.
5.Living in a house whose（of which the）walls are made of glass would be horrible.
6.There weren't any movie theaters in the town where（in which）I spent my last summer.

定語從句中“介詞+which+名詞”結構具體怎麼用？什麼情况下“介詞+關係詞”中的介詞必須在關係詞前？
一、“介詞+which+名詞”結構具體怎麼用？和單獨用which有什麼區別？
如句1-1:It rained all night and all day，during which time the ship broke in pieces.
不是說時間狀語就用when=介詞+which麼？那我改成句1-2對否？
句1-2:It rained all night and all day，during which the ship broke in pieces.
句2-1:I called him by the wrong name，for which mistake I should apologize.
同理改成句2-2呢？I called him by the wrong name，for which I should apologize.
二、什麼情况下“介詞+關係詞”中的介詞必須在關係詞前？
句3-1:She will never forget the day on which she was married.
據說句3-1中on就必須在which前，於是有結論說介詞+關係詞可以等同於關係副詞時，介詞必須在關係詞前，但也見句3-2成立：
句3-2:This is small house（which）I used to live in.
於是暈了，
三、還有些關係副詞可以當介賓用，這是怎麼回事？如句4-1的where.它什麼時候能當介賓？when能當介賓嗎？
句4-1:She climbed up to the top of temple，from where she could see some things in the distance.

一·你可以試著把從句改成陳述句，which用the替換，句1-1的從句就可改為the ship broke in pieces during the time，如果木有time就不通了啊
二·介詞必須放在關係詞前是用來指代時間啊地點啊之類的，day就是時間.而其它的兩者皆可.其實句3-2也可以這麼表達This is the small house in which I used to live不是嗎
三·可以的句4-1中where指的是the top of the temple這樣一個方位.when也可以.比如they met each other 10 years ago，since when they have been good friends.

在定語從句中什麼時候用which什麼時候用介詞+which？
別截一大片沒用的廢話，通俗易懂的

觀察下麵句子：the house which i visited is beautiful.我參觀的房子很美The house in which i live is beautiful.我住的房子很美.都是定語從句，先行詞是名詞或者代詞，第一句用which，第二句用in which，主要的原因在…

講解介詞加which /whom/whose+名詞的區別.
同上.

我想你問的應該是定語從句部分吧.
一句話：這三個關係代詞用哪個取決於和後面名詞的關係.

名詞從句which前接介詞嗎？或定語從句中介詞後的which是否指代前面的先行詞？
a silicon valley capitalist，takes the problems so seriously that it avoids any edtech investement in which a school or school district would be the main buyer
這裡的which是否指代investement.或者這只是替換where關係副詞的固定形式？
which前面接介詞總是搞得我很糊塗.
一般我的以為，是定語從句前的介詞一定是與從句中謂語動詞有關聯，構成介詞前置.
在這裡我無法把in（which=investement）帶入從句？
還是說這裡句子某個不為人知的角落我沒有發現
而且這種句型，總是會讓我先去想後面謂語應該跟什麼介詞，然後句子就無法隨口而出。思維模式有問題。

定語從句中which指代的都是前面的先行詞，但應注意，使用分隔型定語從句時，先行詞不是直接位於定語從句前.
介詞+which引導定語從句時，要選用合適介詞，應考慮which在從句中的作用，是充當不及物動詞的賓語，還是與介詞一起連用充當從句中的時間狀語、地點狀語等.
it avoids any edtech investement in which a school or school district would be the main buyer這個句子中，which屬於第二種情况，in which即in the investment在從句中作地點狀語.
口語中不太常用複雜的定語從句，通常用分句的形式就可以表達相同的含義，可以多聽聽talk show驗證一下.

什麼樣的定語從句介詞要提前？
比如The time of year in which you were born decides your star sigh.

先行詞為the time of year，生於…片語為be born in…，囙此在which前需要加介詞in.又如this is the room which I once lived in/this is the room in which I once lived.介詞提前或不提前都可以.

定語從句中國介詞不可提前的情况
我看到資料書：“定語從句中關係代詞可以做動詞或介詞的賓語，且介詞可以提到關係代詞之前，但固定動詞短語中的介詞則不可提前.如：look after，take care of，care for，see to.”
但我完全看不懂它說什麼，有誰能解釋一下嗎？（有提高懸賞的機會）

這個很簡單，比如句子she is the girl which i am looking after.後面的after不能提前是因為look after是一個固定短語，表達的是一個固定的意思，所以不能提前.如果提前了，那麼從句的意思就不完整了，不再表達她是我照顧的那個女孩的意思
