名词性的引导词和定语从句引导词的区别 需要详细
1. 定句 引导词：① that, which, who, whom, whose, as ② when, where, why 2. 名词性从句 引导词：① that ② whether, if 词 (what, which, who, whom, whose, when, where, why, how等 ) ④ wh- ever *特别注意： ①定语从句的任一引导词均在定语从句中作成分。
②名词性从句的引导词中that 和whether\\\/if 是不作成分的；但是疑问词和wh-ever 在从句中要作成分。
怎么看句子是定语从句还是名词性从句
定语从句是形容词性从句,是用来修饰句子的,即在句中做定语,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.举个例子：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.括号内容是用来修饰the man.,即相当于一个形容词.而名词性从句分为主语从句、宾语从句、表语从句和同位语从句,下面简单举例eg:（Who will win the match） is still unknown.由who引导主语从句,作主语She will give （whoever needs help a warm support）由whoever引导宾语从句,作句子宾语That is （why he didn’t come to the meeting）由why引导表语从句,在句子中作表语I have no idea （when he will come back home.）由when引导同位语从句,在句子中作同位语,对idea作具体解释.
名词性从句可做定语么，因为名词好像也可以修饰名词或代词。
应该是不可以的...名词性从句对另外一个名词的作用应该不是修饰而是解释,或者下定义如果名词后面跟名词性从句的话,这个从句应该是表语从句或者同位语从句而不是定语从句二者的区别就在于定语从句是起修饰作用,即阐述其修饰的名词的某一方面性质.而表语从句和同位语从句是起解释作用,即就名词的实质而下定义. 至于你说的名词修饰名词的情况是存在但是那一般是跟另外一个名词一起构成一个固定搭配或者复合性名词名词性从句应该是不可以作定语来修饰名词的
名词性从句和定语从句有什么区别
两句话就可以解决所有问题,概念清晰后才可以做进一部的细分.1、名词从句：句子中某一部了少了一个名词性的成份,用了一个句子来代替它,这就是名词从句2、定语从句：从句做了定语修饰先行词,名词或代词.因为英语中没有这样的单词有这样的意思简单两个例子：一、名词从句：不管你怎么做都不可能成功.whoever came here is welcome.（无论谁到位这里都）很受欢迎.因为没有这样的词有这样的意思,那这个句子whoever came here就相当一个名词做了句子的主语.类推,代替宾语的,就是宾从,代替主语的就是主从,代替表语的就是表语,代替同位的就是同位语从句.二、定语从句：名子做定语来修饰先行词的.A girl who has long hair.（一个留长发的）女孩,看明白了吗,定从是要用句子来当一个词来修饰别的名词或代词的,因为英语中没有样意思的词（一个留长发的）.
什么是状语从句
什么是名词性从句，请分别作出解释并举例说明。
状语从句指句子作状语时，起副词作用的句子。
I will call you as soon as I arrive in Beijing.(as soon as引导时间状语从句)在句中起名词作用的句子叫名词性从句，包括主语从句、宾语从句、表语从句和同位语从句
名词性从句和定语从句的区别是什么
名词性从句包括宾语，表句，同从句，主语从句。
定语从句不属词性从句。
名词性从句包括：主语从句、宾语从句、表语从句和同位语从句，多由连词that，wh-疑问词或由what，whatever等关系代词引导。
1.主语从句 1)主语从句在句子中充当主语，句子的谓语动词用第三人称单数。
如： What is happening outside does not concern us.外面发生的事与我们无关。
2)主语从句前的that不能省略，仅起连接作用，有时为了保持句子平衡，that从句后置，而由it作形式主语。
如： It is estimated that a round-trip to Mars would take more than a year.据估计，飞到火星来回的时间要超过一年。
2.宾语从句在句子中充当宾语。
如： I don't know where the sound came from.我不知道声音是从哪里来的。
Don't be satisfied with what you have achieved.不要满足于你已取得的成绩。
3.当从句放在系动词be，look，remain，seem等后，即构成表语从句。
如： The trouble is that I have lost his address.麻烦的是我弄丢了他的地址。
It seems that as if it is going to snow.看起来天要下雪了。
4.同位语从句 1)同位语从句是对与之同位的名词中心词作进一步解释。
能接同位语从句的常见名词有：idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, problem, thought, certainty, likelihood, on condition that, on the ground, with the exception, in spite of the fact, on the pretence等。
The news that he has passed the examination is exciting.他通过考试的消息令人振奋。
I lent her the book on condition that she would return it before Sunday.我把书借给了她，条件是她在星期天之前还给我。
2)同位语从句与定语从句的区别在于：定语从句是对先行词加以修饰、限制，而同位语从句是为了说明中心词的具体内容；that在定语从句中充当成分，为关系代词，而在同位语从句中不作任何成分，仅起连词作用。
如： The fact that we talked about is very important.我们讨论的情况非常重要。
(定语从句) The fact that he succeeded in the experiment pleased everybody.他实验成功的事实使每个人都很高兴。
(同位语从句) 5. whether与if在名词性从句中的区别。
if一般只用于引导宾语从句，而whether可引导包括宾语从句在内的其他名词性从句。
1)连词whether引导的主语从句、表语从句不能用if来替换。
Whether he will attend the meeting is uncertain.他是否来参加会议并不确定。
2)宾语从句中，whether常与or not搭配，可以说whether or not，而不说if or not。
I don't care whether or not she will attend the meeting.她是否来参加会议，我不介意。
3)whether可用在介词后，或不定式前，if则不可。
She doesn't know whether to get married now or wait.她不知道是现在结婚呢还是等等。
4)在某些动词后面(如discuss)只能用whether,不用if。
We discussed whether we should go on climbing.我们讨论了是否继续攀登。
用状语，定语，名词性从句翻译下列句子
1. You can do whatever you want to (do).2. Whether you'll succeed mainly depends on what you do and how you do it.3. The teacher asked how many English songs you had learned.4. We don't understand what you said just now.5. It is unclear why he did that.6. What he wants is a book.7. It remains a puzzle how he succeeded.8. As is known to all, light travels in a straight line.9. The first English song I've ever learned is the ABC song.10. That's the doctor who saved the child's life.11. This is the pen (which\\\/that) my brother bought for me.12. Beijing is the place where I was born.13. I'll remember the day when I went to London forever.14. He was reading a book when he heard a knock at the door.15. We've lived in Beijing since we came here.16. We'll live here until his mother comes.17. Since the class is over, let's go to play basketball.18. As\\\/So long as I'm alive, I'll never give up learning.
引导定语和名词性从句，从句都得是完整的句子吗
这里不是从句，是强调句，card是被强调的部分强调句结构：It is (was) 被强调部分+ that (who) + 句子其他部分It is.....that....中it是没有意思的，that也不是引导词只是用来强调某一部分的工具
这两个句子是定语从句还是名词性从句，为什么
名词性从句，一般是充当主语、宾语或表语，也就是说，假如把它去掉，句子就不完整了。
而定语从句只是用来修饰句子中的某个成分的，所以去掉的话，主句还是完整的句子。
所以Farther was in the engine room ,where the third engineer was killed 这个句子中，where引导的是一个定语从句，把它去掉，句子还是完整的句子。
第二个尽管句子不完整，但从意思来看，应该是一个定语从句
前面应该有一个先行词吧
