【正文】 在句中作主語或賓語, 因此修飾人時可代替who 或whom, 修飾物時可代替which, 但that 不能直接作介詞賓語Who is the person that is speaking now?They talked about the persons and things that they remembered at is the very book that I’ve been longing ：When: 修飾表時間的名詞, 如time, hour, day, month, date, year等, 在從句中作時間狀語Do you still remember the day when you first came to school?The first time that I came to school was in can’t remember the exact time when(that)I went to visit the Great Hall of the ？不是的！要具體分析該名詞在從句中的成分，如：The day which / that I can’t forget was my first day at can’t forget the day when I first met : 修飾表示地點的名詞,在從句中作地點狀語It’s the room where I used to live in my factory where we worked last year is now being ？不是的！要具體分析該名詞在從句中的成分，如：You father once worked in the factory which we visited yesterday, didn’t he?I often think of the days which I spent together with my : 表原因, 在句中作原因狀語從句, 只修飾先行詞reasonDo you know the reason why he is absent today?三、關系代詞和關系副詞有何區(qū)別主要是它們在從句中所起的作用不同。關系代詞在從句中一般作主語或賓語。而關系副詞在定語從句中作狀語。分清楚這一關系并在做題時想著這個原則，就不會出原則性的錯誤了。四、定語從句解題步驟——重點。，也就是在定語從句中擔任何成份。這一點可以幫助我們劃分使用關系代詞還是關系副詞。eg：This is the place that/which I visited years is the place where I lived years ：這兩句的先行詞都是the place，由于第一句中的先行詞在定語從句中作visit的賓語，所以選擇關系代詞，如果作賓語時關系代詞可省略。而第二句的先行詞則在定語從句中作狀語，因為live是不及物動詞，因此選擇關系副詞where。五、關系代詞中的which和that如何區(qū)分在先行詞為物情況下，一般情況兩者可通用，但也有不可互換的情況。以下幾種情況只用that：, everything, nothing, something, anything, little, much 等不定代詞He did all that he can to help is nothing that can be done in this (that)we saw was of great interest to ’ve read all the books(that)you gave , every, no, some, any, little, much, 等修飾。The Summer Palace is the most beautiful park that I’ve been first thing that I should do after returning to China is to see my old is the best novel(that)I have ever is the first position(that)he has written in only, the very, the same, the last, the next 修飾時。That white flower is the only one that I really is the very book that I want to last place that we visited was the chemical oxygen the only gas that helps fire burn?Is this the same tool that you used yesterday?That white flower is the only one(that)I really is the very book(that)I want to last place(that)we visited was the chemical ，從句應用that,而不是其他。He talked about the teachers and schools that he had visited in talked for about half an hour of persons and things that they remembered at , which 開頭的特殊疑問句時，定語從句多用that,而不用who(whom),which。Who is the person that is standing at the gate?Who is the man that called on you just now?Which of the subjects that you are studying is the most difficult.?只用which 不用that 的情況：The bus, which was full, was surrounded by an angry This is the room in which planned our future we go to a hill at the top of which was a The room which / that we live in is very clean and Bamboo is hollow, which makes it very tried to make some excuses, which made his teacher very tried to catch the moon in the water, which was 單項填空：從A、B、C、D中選出可以填入空白處的正確答案。 is the only one of the students _____ the knows knows you know the girl _____? he often talk who he often talks that he often often talks to world _____ we live is made up of which which are no children _____ love their do does not’m one of the boys _____ never late for are is Lincoln, _____ led the United States _____ these years, was _____ of the greatest 。for。in。one。at。through。one is the girl _____ wearing a red dress?’s old man _____ yesterday is a spoke to I I spoke to him young man _____ is an engineer of our you just you just talked to you just talked you just talked dictionary _____ is sold out in the you need you need you need it this the shop _____ sells children’s clothing? is the most satisfactory place _____ we’re going to which magazine _____ Betty paid one dollar was very which two things _____ they felt very proud were Jim’s gold watch and Della’s which which was the man _____ Master of Game was who him is the museum _____ we visited last which this museum _____ we are going to visit tomorrow? one of me I saw a woman _____ I thought was my is the key you are looking which you are looking that you are are looking for which woman _____ is his whom he takes that he takes care takes care he takes care答案：1—5 ADDAB6—10 DDBBA11—15 ACCBA16—20 ADAAC難題解析：17題，要把一般疑問句還原成陳述句，This is museum…由于museum前少了冠詞不合英語語法，所以要補充完整就是：This museum is the one we are going to visit ，得出一般疑問句應該是Is this museum the one we are going to visit tomorrow?
