D yu knw where the party will be held？(√)

4．what与that的用法
that是从属连词，在名词性从句中不充当任何成分，也没有任何意义。而what是连接代词，在名词性从句中充当成分，通常充当主语、宾语或表语。
I believe that I will succeed if I study hard.
我相信如果我努力学习我会成功的。
I believe what he said because he is an hnest man.我相信他说的话，因为他是个诚实的人。
5．whether与if的用法
(1)用whether或if均可的情况
①引导大部分动词后的宾语从句时，两者均可使用。
②it作形式主语，且主语从句在句末时，两者均可引导主语从句。
(2)用whether而不用if的情况
①引导主语从句置于句首时；
②引导表语从句和同位语从句时；
③引导介词的宾语从句时；
④引导词与r nt连用时；
⑤引导词后接t d时；
⑥有些动词如discuss，decide等后的宾语从句。
6．what，wh，which与whatever，whever，whichever 引导名词性从句的区别
(1)what引导名词性从句意为“什么”，带有疑问意味；意为“……的事情”，表示肯定的意思。wh意思是“谁”，带有疑问意味；which意思是“哪一个”，带有疑问意味。
D yu knw wh brke the windw?
你知道是谁打坏的窗子吗？
(2)whatever，whever，whichever意思分别为“所……的一切事或东西”“任何……的人”“……的任何一种东西”等，并且充当成分，相当于anything that，anyne wh等。
She is very dear t me.We have been prepared t d whatever it takes t save her life.＝She is very dear t me.We have been prepared t d anything that it takes t save her life.
她是我的至亲，我们已经准备好了不惜一切代价救她的命。
7．that不可省略的情况
(1)that引导主语从句且从句置于句首时；that引导表语从句时；that引导同位语从句时；当it作形式宾语，that引导的从句作真正的宾语时。
(2)当主句谓语后接两个或两个以上的宾语从句时，第一个that可省略，其他的that不可省略。
She said (that) her ambitin was t enter a key university，that she wuld study hard t make her dream cme true，and that she wuld live up t her parents’ expectatins.
她说她的志向是考上一所重点大学，她会努力学习，实现自己的梦想，不辜负父母的期望。

常见的抽象名词有news，idea，fact，prmise，cnclusin，thery，questin，dubt，thught，hpe，message，suggestin，wrd(消息)，pssibility，decisin等。
At first many peple were astnished at the cnclusin that the earth was nt the centre f the universe.起初很多人对地球不是宇宙中心这一结论感到惊讶。
9．why与because 引导表语从句的区别
why与because 引导表语从句时，前者强调结果，后者强调原因。
I had a cld.That was why I didn’t attend schl.我感冒了，因此我没去上学。
I didn’t attend schl. That was because I had a cld.我没去上学，那是因为我感冒了。
注意：(1)句子的主语为the reasn时，表语从句用that引导，表示原因，此时不用because。
The reasn why she was ill was that she had eaten bad meat.
她生病的原因是她吃了变质的肉。
(2)由why引导的从句作主语时，表语从句用that引导。
Why we decided t put ff the match was that the weather was t terrible.
我们决定推迟比赛的原因是天气太糟糕了。
10．as if/thugh引导的表语从句
as if/thugh引导的表语从句通常置于系动词lk，seem，sund，be等后面，从句中既可以用虚拟语气，也可用陈述语气。
It sunds as if smebdy is kncking at/n the dr.听起来好像有人在敲门。
She treats him as if he were a stranger.
她待他如陌生人。
11．同位语从句和定语从句的区别
同位语从句是用于解释说明所修饰名词的具体内容的，而定语从句是对作先行词的名词的限制、描绘或说明。that在同位语从句中只是连接主从句，没有任何意义，不在从句中充当句子成分；that在定语从句中是关系代词，不但连接主从句，而且指代被修饰的名词或代词(即先行词)，在从句中作主语、宾语和表语。
I had n idea that Brisbane has s many peple! (that引导同位语从句，不能省略)
The idea (that) he put frward at the meeting is very reasnable.(that引导定语从句，作宾语，可以省略)
