She will marry as healthy a man as she can find .她将嫁给她能找到有钱人。（作宾语） 注意：
1、先行词中有the same修饰时，定语从句也可用that引导，但意思上有区别，as表示与此同类；that表示就是那一个，同物。例如:
I have bought the same watch as you have. 我买了一块和你一样的手表。（我的手表和你的手表很像，但不是同一块。）
This is the same watch that I lost.这就是我丢的那块手表。（这手表和我丢的手表是同一块）
2.such/so…as…和such/so…that…的区别：前者引导的是定语从句，as在从句中充当成分（主语，宾语）；后者是引导结果状语从句，意为“如此…以至于…”，在此句型中，as是不充当成分的，因此在判断时关键看从句中是否缺少成分（主语或宾语）。如： This is such an interesting book ______ everybody wants to read. This is such an interesting book ______ everybody wants to read it.
分析这两个句子不难看出，第一个句子是定语从句，因为从句中缺少宾语；第二个句子是状语从句，因为从句中主谓宾齐全。所以第一个空填as，第二个空填that。
3.在whose引导的定语从句中，当whose修饰物时，“whose+名词”相当于“the+名词+of which”或者“of which +the+名词”的形式，如：
The classroom whose door is broken will soon be repaired.=The classroom of which the door is broken will soon be repaired.
Do you like the book whose cover is yellow?= Do you like the book the color of which is yellow?
4. 用those作定语从句的先行词，通常指人，当定语从句中缺少主语时，关系代词用who,定语从句中谓语动词用复数。如：
I’ll never respect thosewhodon’t respect others.我决不会尊重那些不尊重别人的人。 5. one of+复数名词+定语从句的结构，如果one前面有the (only/last/first/right等) 等限定词修饰时，则one是先行词，定语从句中谓语动词用单数，否则先行词是复数名词，定语从句谓语动词用复数。如： .John is one of the students who have the keys.（先行词是students） John is the only one of the students who has the keys.（先行词是the only one）
改错练习：
1. Those who wants to go with me put up your hands. 2. The boy, his mother died last year, studies very hard.
3. He is the only one of the students who have been invited to the English Evening. 4. That is the way which they work.
5. Those have questions can ask the teachers for advice.
答案：
1. wants→want。定语从句中谓语动词的数应与先行词一致。
2. his→whose。
3. have→has。当one of+名词复数作先行词时,从句的谓语用复数;但是当one前有the (only) 时,从句谓语要用单数。
4. which→that/which前加in或去掉which。 5. Those后加who。
★ 只能用关系代词that的情况：
1.先行词为all, everything, nothing, something, anything, few, little, much, the one等不定代词时。如：We’ll do all that we can to protect the endangered plants and animals. 2. 先行词被all, every, no, some, any, much, (a)few, (a)little等不定代词修饰时。如： You can borrow any book that you want to read in our school library. 3.先行词被序数词或形容词最高级修饰时，或本身是序数词、基数词、形容词最高级时。如：
This is the most beautiful city that I’ve ever seen. She was the first friend that I made here. 4. 先行词被the only, the very, just, the last, the right,等修饰时。如： This is the very factory that they visited last summer holiday. 5. 先行词是并列结构，既有人又有物时。如：
He talked happily of the writer and his books that interested him.
★只能用关系代词which的情况： ①当关系代词的前面有介词时.
1.A zoo is a park in which many kinds of animals are kept for exhibition. 2.Is this the room in which Mr. White lives? ②在非限制性定语从句中.
1.Crusoe's dog, which was are now very old, became ill and died .
2.More and more people are beginning to learn English, which is becoming very popular in our country.
(which指代主句)
