用列举句子来讲解下宾语。定语从句怎么辨别？

Question

我一直不清楚怎么辨别。希望帮帮忙。举例子来讲解。

Answer 1

宾语从句的上面回答很多了，就回答定语从句吧。 (定语从句)
在复合句中修饰名词或代词的从句叫做定语从句。被定语从句修饰的名词或代词叫做先行词。定语从句必须放在先行词之后，对其先行词起限定作用。
This is Tom.
Tom gave us a talk yesterday.
This is Tom who (that) gave us a talk yesterday.
先行词 定语从句
引导定语从句的关系代词有：who, whom, whose, that, which
引导定语从句的关系副词有：where, when, why
一、 who, whom, whose引导的定语从句
1. who 在从句中作主语，不可省略，它所引导的定语从句所修饰的先行词必须是人。
e.g. This is the doctor who came her yesterday.
2. whom在从句中作宾语，它所引导的定语从句所修饰的先行词必须是人，可以省略。
e.g. The man (whom) you saw last week has left the town.
注意：在从句中作介词宾语时，介词一般可放在whom之前，也可放在原来的位置上。在含有介词的固定动词词组中介词只能放在原来的位置上。e.g.
a) The man from whom I borrowed the book is Li Lei. = The man whom I borrowed the book from is Li Lei.
(前句中的whom不可省略，后句中的whom可省略)
b) The girl whom he is taking care of is ill. (take care of是固定词组)
3. whose在从句中作定语，表示所属关系，其所修饰的先行词既可是人也可是物。
e.g. I know the woman whose husband is a doctor.
He lives in the house whose window faces south.
二、 that, which引导的定语从句
这两个代词均指物，它们所引导的定语从句所修饰的先行词是物,通常情况下，它们可以互换。
1. that, which在从句中作主语，不可省略。
e.g. Hero is the film that/which was directed by Zhang Yimou.
2. that, which在从句中作宾语，可以省略。
e.g. Is this the film (that/which) you talked about last week?
注意：关系代词在作介词宾语时，只能用which且不能省略。
e.g. The house in which he once lived is a meeting-room. = The house (which) he once lived in is a meeting-room.
知识拓展：
引导定语从句的关系代词that和which，在一般情况下，尽管可以互换使用，但在下列情况下，只能用that，而不用which：
1. 先行词是复合不定代词everything, anything, nothing等时。
e.g. She didn’t forget anything (that) her mother had told her to buy.
2. 先行词被序数词或the last修饰时。
e.g. This is the first textbook (that) I studied in the primary school.
He is in the last row that is next to the window.
3. 先行词被形容词最高级修饰时。
e.g. That is the highest building (that) I have ever seen.
4. 先行词被the only, the very, the same等修饰时。
e.g. This is the very novel (that) you want to borrow.
5. 先行词是或被all, no, some, any, little, much等修饰时，
e.g. I’ve written down all (that )the teacher doesn’t allow us to do.
They haven’t got any dictionaries (that) we need.
6. 先行词既包含人又包含物时。
e.g. He told us many interesting things and persons (that) we had never heard.
7. 主句是以who, which引导的特殊疑问句时。
e.g. Who is the man (that) you spoke to just now?
Which is the book that was stolen by him?
8. 先行词是主句的表语或关系代词在定语从句中作表语时。
e.g. China is no longer the country (that) it used to be.
三、关系副词where, when, why引导的定语从句（在从句中作状语）
1. where表示地点，它引导的定语从句修饰表地点的先行词。
e.g. This is the village where he was born.
c.f. This is the village (that/which) he visited last year.
2. when表示时间，它引导的定语从句修饰表时间的先行词。
e.g. I’ll never forget the day when I joined the League.
c.f. I’ll never forget the day (that/which) we spent together.
3. why表示原因，它引导的定语从句修饰表原因的先行词。
e.g. The reason why he didn’t come yesterday is quite clear.

Answer 2

在句子中起宾语作用的从句叫做宾语从句，一般处于谓语动词后。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。 He told me (that ）he would go to college the next year 　　他告诉我他明年上大学. 　　I don’t know if there will be a bus any more. 　　我不知道是否还会有公交车. 　　Nobody knew whether he could pass the exam. 　　没有人知道他是否会通过考试. 定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 (1) Is he the man who/that wants to see you? 他是那个想见你的男人吗？（who/that在从句中作主语） 　　(2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 　　（3）The man whom you spoke to just now is our English teacher 你刚刚说话的那个男人是我们的英语老师希望你能满意
