A. 英語語法定語從句
1.定語從句的定義：用作定語的從句叫定語從句。
2.先行詞：被定語從句所修飾的名詞或代詞。
3.定語從句的位置：緊跟先行詞(名詞或代詞)之後。
4.引導詞：引導定語從句的詞(包括關系代詞和關系副詞)。
﹙1﹚關系代詞：that/who/whom/which/as
﹙2﹚關系副詞：when/where/why
5.引導詞的位置：位於定語從句之前(先行詞之後)。【as除外】
6.引導詞的功能(作用)：
﹙1﹚連接先行詞和定語從句。
﹙2﹚在定語從句中充當一定的成分(關系代詞充當主語或賓語，關系副詞充當狀語)。
7.定語從句的類型：
﹙1﹚限定性定語從句(主句和定語從句之間無逗號)。
① 直接由引導詞引導定語從句
The man who you』re talking to is my friend.
② 由介詞+關系代詞(whom/which)引導
The man to whom you』re talking is my friend.
I need a pen with which I can write a letter.
=I need a piece of paper on which I can write a letter.
介詞的選用可根據從句中的相關片語確定，該介詞通常可以放在關系代詞之前，也可放在從句之尾。例如：
The man (who/whom/that) I talked about at the meeting is from Beijing University.
=The man about whom I talked at the meeting is from Beijing University.
The palace (which/that) I often pay a visit to was built in the 17th century.
=The palace to which I often pay a visit was built in the 17th century.
﹙2﹚非限定性定語從句(主句和定語從句之間用逗號隔開)。
① 直接由引導詞引導定語從句。
② 由介詞+關系代詞(whom/which)引導。
I live in a house far away from the city， in front of which is a big tree.
There is an apple tree standing at the gate， on which are many apples.
This is the man to whom I gave the book.
③ 由「代詞/名詞+of+whom/which」或「of which/ whom +名詞/代詞」(先行詞指
人用whom，指物用which)引導。One， some， any， none， all， both， several， many， most， neither， either等詞、數詞、分數或百分比與of whom或of which連用。
He has five children， two of whom are abroad.
(比較：He has five children， and two of them are abroad.)
We have three books， none of which is/are interesting.
(比較：We have three books， but none of them is/are interesting.)
除why和that不能引導非限定性定語從句外，其餘引導詞都可以，用法同限定性定語從句一樣。但要注意以下區別。
1.在形式上非限定性定語從句與主句有逗號隔開。
2.非限定性定語從句的作用：它只是補充說明先行詞的情況，翻譯時可譯成兩個句子。
The engineer， whose leg was badly hurt， was quickly sent to hospital.
(那位工程師被很快送往醫院，其腿部受了重傷)
The engineer whose leg was badly hurt was quickly sent to hospital.
(那位腿部受了重傷的工程師被很快送往醫院)
3.在非限定性定語從句中，任何引導詞都不能省略(包括引導詞在此定語從句中充當賓語在內)。指人做主語時只能用who， 做賓語時用whom；
指物做主語，賓語都用which； 關系副詞用when或where，也不能省略。
B. 英語語法定語從句問題
你這兩個句子都是正確的，第一個是含定語從句的句子，而第二句則是現在分詞短語做定語啊。
C. 英語語法 定語從句
1 第一題沒有where這個選項呀！如果有，當然可以選的。
2 沒有in which呀。在做此類題的時候內，可以把從句部分還原，容如：1題中，the papers are kept in the drawer,有介詞in,所以用in which或where(the papers are kept somewhere,副詞前不加介詞的）；而2題中，this idiom can be used in the situation,所以只用which不對。
D. 英語語法定語從句
單純的說定語從句的話
只要明確了什麼是定語
而什麼是句子便可以了
二者綜合成為顧名思義的定語從句
值得一提的是
定語從句基本上充當的是名詞或形容詞性
自然在意義上也屬於名詞或形容詞
祝學業有成！
E. 英語語法定語從句
注意到前面指示代詞those了嗎？those只和WHO搭配。
those用作先行詞的定語從句
一、those who型
當代詞 those 後接定語從句時，定語從句通常用關系代詞who來引導。
如：
Those who earn most pay most tax.
掙錢最多的人交稅也最多。
Thanks are e to all those who helped.
向所有幫過忙的人表示感謝。
Thanks are e to all those who took part.
向所有參加的人表示感謝。
We kept seats for those who might arrive late.
我們給可能來晚的人留了座位。
Apologies to those of you who wrote in to complain.
向那些寫信來投拆的人致歉。
Life goes on for those of us who remain here below.
對於我們凡人來說，生活依舊。
This statue commemorates those who died in the war.
這座雕像是紀念戰爭死難者的。
Only those who had booked in advance were allowed in.
只有那些預先訂票的人可以進去。
Early settlers paved the way for those who arrived later.
早期的移民為後來者奠定了基礎。
Tickets are limited and will be allocated to those who apply first.
票數有限，先申請者先得。
There are plenty of restaurants for those who tire of shopping.
厭煩購物的人有很多餐館可去。
Those who wish to come here will do so at their own risk.
願意來的人都可以來，但責任自負。
He was one of those people who take delight in conveying disagreeable news.
他是那種專喜歡報憂的人。
Inevitably those who suffer the most are the mothers and children.
不可避免的是遭受最大痛苦的是母親和兒童。
The market favored those who had property and discriminated against those who did not.
市場偏愛那些有財產的人，歧視那些沒有財產的。
二、those whom型
當those 後引導定語從句的關系代詞用作賓語時，可以省略作賓語的whom。
如：
He could imitate in speech or writing most of those he admired.
他能模仿大多數自己崇拜的偶像的講話和寫作風格。
Eric was a gifted teacher beloved by all those he taught over the years.
埃里克是位天才的教師，多年來他一直受到所以學生們的熱愛。
He sought reconciliation with those he had stolen from.
他想與那些曾被他盜竊的人尋求和解。
Build on the qualities you are satisfied with and work to change those you are unhappy with.
以自己滿意的優點為發展基礎，努力改變自己不滿意的地方。
三、those whose型
當those 後引導定語從句的關系代詞用作定語且表示所屬關系時，關系代詞用whose。
如：
The syndrome is more likely to strike those whose immune systems are already below par.
這種綜合征更容易對那些免疫系統已經低於正常水平的人構成威脅。
四、those that / which型
許多人認為，those 後的定語從句只能用who 來引導，不能用that 或which，其實是誤解。
1. 當先行詞those 指人時，其後的定語從句可以用who 來引導，也可以用that 來引導，但以用who 引導為普通。
如：
None are so deaf as those that will not hear.
最聾的人莫過於不願聽別人意見的人。
His simple message was that God will punish those that do evil.
他的意思非常簡單：上帝將會懲罰作惡者。
2. 當先行詞those 指事物時，其後的定語從句不可以用who 來引導，可以用that 來或which 來引導。如：
The votes in the marginals are those that really count.
邊緣席位的選票才是最關鍵的。
The design of the new house is similar to those that have already been built.
這棟新房子的設計與已經建好的那些房子相似。
We must try to find out those which may be attacked most easily.
我們必須設法找出容易受攻擊的東西。
You are asked to indicate those which most describe your personality.
要求你指出最能表明你性格的那些方面。
另外注意，those後可接定語從句，但these後習慣上不接定語從句。

G. 英語語法 定語從句
這明顯是語法錯誤，書中例句是有問題的，因為從句完整，所以應該用關系副詞when
H. 英語語法定語從句
因為我們不說on the year
I. 英語定語從句，語法
定語從句中，連接先行詞和定語的叫關系代詞或關系副詞。有一些情況下，關系代詞可以省略：
1、當關系代詞所代替的先行詞在定語從句中做賓語，關系詞可以省略。Whoistheman(that/who/whom)youweretalkingto? 剛才和你講話的人是誰？
2、當關系代詞that在定語從句中用作表語時，可以省略。
Chinaisnotthecountry(that)itwas. 中國已不是過去的中國了。
3、關系副詞when用於day,year,time少數詞後時可以省略（也可換成that）Thatwastheyear(that)Ifirstwentabroad. 就是那一年我第一次出國。
4、關系副詞where用於place, somewhere, anywhere, everywhere, nowhere少數詞後時可以省略(也可換成that)。
Thisistheplace(where)theymetyesterday. 這就是他們昨天碰頭的地方。
5、當關系代詞that在定語從句中用作賓語補足時，可以省略。
I』mnotthemadman(that)youthoughtme. 我並不是你所認為的那個瘋子。
6、關系副詞why通常只用於the reason後引導定語從句，且通常可換成that或for which，這些連接詞都可以省略。
That』s the reason (why, for which, that) he came. 這就是他來的原因。
Give me one reason (why) we should help you. 給我舉出一個我們應當幫助你的理由。
如有疑問，請追問，滿意，請採納，謝謝。
J. 英語定語從句語法
定語從句是在句子中充當定語成分的從句，修飾名詞和代詞，即主語和賓語。下面是我認為比較要的點（從網上找的）。
That 指人或物 which 指人或物（定語從句中）
[注意] 1、because與so；(al)though與but；if與so不可以同在一個句子中成對出現。
2、時間、條件、原因,讓步狀語從句放在句首時需要用逗號與主句隔開。
條件狀語從句中沒有將來時，用一般現在代將來。
定語從句：在復合句中作定語用修飾句子中某一名詞或代詞的從句叫定語從句。 ① 定語從句的位置：放在名詞或代詞的後面。如：The man who has an umbrella in his hand is my uncle.
② 語法術語的改變：被修飾的名詞或代詞稱為先行詞；引導定語從句的連接詞稱為關系詞,其中that、which、who稱為關系代詞,where、when、how稱為關系副詞。
③ 關系代詞或關系副詞的作用：關系代詞who、whom 和whose指人,分別在從句中作主語、賓語和定語。which指物，that多指物, 有時也指人,它們在從句中可以作主語或賓語。定語從句中關系代詞作從句賓語時可以省略。This is the thief (that/who/whom) we have been looking for these days. / Please find a room which is big enough for all of us to live in.關系副詞when或where引導定語從句時,它們在從句中分別作時間狀語和地點狀語。如：This is the room where they had a quarrel a week ago. / I can never forget the day when I first saw you.
④ 限制性定語從句和非限制性定語從句。限制性定語從句在句中不能省略,否則主句意思就不完整。非限制性定語從句和主句之間往往用逗號分開,這種從句是一種附加說明,如果從句子中省去,也不至於影響主句的意思。如：She spent the whole evening talking about her latest book, which none of us had heard of.
[註解] 1、關系代詞只能用that的情況：當先行詞是指事物的不定代詞(all, anything等),或先行詞部分含有最高級,或含有序數詞時,不能用其他的關系代詞,只能用that. 如：All that Lily told me seems untrue. / Can you give me anything that has no sugar inside? This is the first two-story bus that runs in our city.
2、先行詞既有指人的名詞又有指物的名詞時，關系代詞用that而不用which.
Do you know the things and persons (that) they are talking about?
3.、主語是there be 句型時關系代詞用that。
There is a book on the desk that I am very interested in.
3、關系代詞在從句中作主語時一般用who(指人)、that(指物),而不用that指人或用which指物。 如：Do you know the woman who is weeping in the corner(? / Do not tell me any words that have nothing to do with me.
4、關系代詞作從句的賓語時,常用which或whom,較少使用that或who,而且,關系代詞常常省略。如：Tom』s father was the first parent whom our teacher talked to.
5、當關系代詞緊跟在介詞後面時,必須用which或whom,而當介詞移到句尾時,則又可以使用that或who. 如：This is the room in which Miss Li once lived. (= This is the room Miss Li once lived in.
6、as引導非限制定語從句位置較靈活，可以放在主語前中後，which 引導的定語從句只能放在主語之後。
As everybody knows, Shakespeare is a famous writer.
Shakespeare, as everybody knows, is a famous writer.
Shakespeare is a famous writer, as everybody knows.
The plan worked out very well, which is more than we could expect.
.
5. 只用which,不用that的情況:
引導非限制性定語從句時;
引導詞前有介詞時;
一個句子中若有兩個定語從句,一個用that引導,另一個用which引導;
e.g. He bought a book that could give him much knowledge and which could help him to kill the time.
6. 當those作為先行詞指人時,通常只能用who引導;
as 從句的先行詞是the same, such, 或被他們所修飾;多用於表示肯定意義的從句中,不用於表否定意義的從句中.
e.g. Many of the sports are the same as they were when they started.
The result was not such as he expected.
It was raining hard, which(as) was unexpected.
8. 介詞+關系代詞要根據
謂語動詞的固定搭配 e.g. This is the evidence with which the case is connected.
先行詞 e.g. I'll never forget the day on which\when I joined the party.
c. 句子表達的意思 e.g. The boss in whose department Mr King worked got sacked.
d. 在非限制性定語從句中,名詞\代詞+of+which\whom表示整體與部分的關系
e.g. The workers, some of whom stayed for four years, came from different countries.
e. 介詞的位置一般放在關系代詞之前,有時也可放在從句中原來的位置上.
e.g. We did it in the same way in which he did\which he did in.
9. That 作為關聯詞可以當作關系副詞用
e.g. This is the house in which Louis XIII lived.
This is the house that Louis XIII lived.
This is the house where Louis XIII lived.
This is house which Louis XIII lived in.
This is the house Louis XIII lived in.
