What funcitn (功能) f Taiwan in these sentences?
及物动词和介词之后是宾从
抽象名词 n. 之后是同位语从句；多用that引导
We knw (that) Taiwan belngs t China. （ ） 从That Taiwan belngs t China is a fact. （ ） 从=It is a fact that Taiwan belngs t China. 3. The fact is that Taiwan belngs t China. （ ） 从 4. We knw the fact that Taiwan belngs t Chin （ ） 从
动系之前是主语从句 动介之后是宾语从句系动词之后是表语从句。抽象名词之后是同位语或定语从句
The idea that he came up with is very gd.2. The idea that we will hld a party is gd.
1. The news that he gt is very exciting. 2. The news that he is admitted int Beijing University excited us.
1.从句的作用 定语从句：修饰限定先行词 同位语从句：解释说明先行词的内容2.that 的成分 定语从句：作主，宾，表，做宾语可省 同位语从句：不做成分，不能省略
定语从句和同位语从句的区别
常跟同位语从句的抽象名词有:idea; belief; thught;news, wrdfact; truth; message, infrmatinquestin, prblemevidence, prmise;advice,suggestin,request,requirement,rder,,Dubt, chance, pssibility
同位语从句多用that引导
名词性从句包括主语从句、宾语从句、同位语从句和表语从句。考查的要点主要是连接代词和副词的正确使用、主语谓语的语序、双重连接词以及特殊句型的使用等。具体来说主要包括： 1. 名词性从句连接词的区别，尤其是what与that、 whether与if的区别。 2. 名词性从句中的语序和时态。 3. it作形式主语、形式宾语的情况。 4. whever/whatever/whichever引导名词性从句
连接代词（主宾表定） ：what/which/wh/whm/whse
连接副词(做状语）： where ; when; why ;
一、名词性从句连接词的选用
(1) that 和what 的选用
that 和 what 都可引导所有的名词性从句。但是，what除起连接作用外，还在名词性从句中充当成分，可作从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。
A.that B. what
1. ______ he wants is a bk.2. ______ he wants t g there is bvius. 3. The result is ______ we wn the game. 4. This is _____ we want t knw. 5. Is _____ he tld us true? 6. We shuld pay attentin t ______ the 　teacher is saying. 7. I have n dubt _____ he will cme. 8. I have n idea ____ he did that afternn.
a. 主语从句 b. 表语从句 c. 同位语从句 d. 介词后的宾语从句 e. whether t d 做动词宾语不能用if t d. f. 与 r nt 连在一起引导宾语从句 时不用if.
if和whether的选用
不能使用if 的情况:
Culd yu tell me where he lives? ( ) Culd yu tell me where des he live? ( )
二. 疑问词引导的名词性从句要求使用陈述句语序，不能用一般疑问句语序。
Hw was he successful is still a puzzle. ( ) Hw he was successful is still a puzzle. ( )
你能告诉我他住在什么地方吗？
他告诉我他正在为考试做准备。 He tld me _________________________________.他说他已离开家乡十年了。 老师告诉我们光是沿直线运行的。 The teacher tld us _________________________.
he was preparing fr the examinatin
light travels in a straight line
时态：如果主句谓语是过去时,从句谓语动词一般用过去的某种时态,但从句表达的是客观事实、真理、自然规律等时,从句谓语通常用一般现在时。
1.以it作形式主语的五种句型： （1）It + be + 形容词/名词词组+ that 从句（2）It + be + 过去分词+that从句。（3） It + seem, happen等不及物动词 + that从句  It happened that I was ut that day.  （4） It + desn’t matter + wh从句。 （5）It + 及物动词 + 宾语+ that从句。 It surprised me that he was half an hur late n such a shrt jurney.What surprised me ____ that…..
三. It 作形式主语和形式宾语的情况
2.以it作形式宾语的六个动词：一“使”五“认为” make, find, feel, think, believe, cnsider +it +adj/n+that 从句。
例如：He made it clear that he wuldn’t g t his party.I think it my duty that I help him.I find it easy t learn English.
He will believe whatever she says. （宾语从句不能用n matter what代替whatever）Whever breaks the law shuld be punished. (主语从句，不能用 n matter wh 代替)Whatever she says, he will believe it.（可以用n matter what代替whatever）
四：whatever, whichever, whever, 等与 n matter what, n matter which, n matter wh, 的区别:前者既可以引导名词性从句，也可以引导让步状语从句，而 n matter 加疑问词只能引导让步状语从句。
1. Sarah hpes t becme a friend f ____ shares her interests. A. anyne  B. whmever C. whever D. n matter wh
2. ____ much advice I gave him, he did exactly what he wanted t d. A. Hw B. Whatever C. Hwever D. N matter
3. It is generally cnsidered unwise t give a child ____ he r she wants. A. hwever  B. whatever C. whichever  D. whenever
The reasn _____ we didn’t trust him was _____ he ften lied．2. The reasn ____ he gave fr his absence was ______ he was ill.
reasn后面的表语从句只能用that引导, 不能用why引导, 但reasn后面的定语从句可以用why或者that 引导。
在名词性从句中，我们还需特别注意以下问题：
